Rear Axle Drive Pinion May Fracture – 2021 Rosenbauer Commander & Warrior

SEOCONTENT-START

Chronology for 22V-025 Safety Recall for Meritor Rear Axle From Lisa Sampson, Compliance Manager at Rosenbauer As of April 15, 2022 On January 5, 2022 Rosenbauer was alerted in a meeting that we had recalled product from Meritor. Rosenbauer started analyzing the details from Meritor and therefore, identify where the impacted trucks are located and filed the appropriate paperwork for the recall. Rosenbauer asked for additional information from Meritor including the remedy for delivered trucks and trucks in production. The information was received and Production was alerted. Rosenbauer then worked with Meritor to remedy the trucks in Production immediately. All but one truck identified to be in production was inspected and remedied by Meritor the week of 2/14/22 at Rosenbauer’s facilities. There is one final truck that once complete at our Nebraska location, will travel back to SD and receive the inspection and remedy. Rosenbauer Compliance will maintain communication with Rosenbauer Production & Meritor to check when the truck will be available for inspection/repair. Inspection by Meritor involved using an eddy current ultrasonic testing tool to verify the pinion is intact. All inspections for trucks in Production were completed by Meritor technicians as Rosenbauer supplied indoor space and common tools as requested. On March 4, 2022, Rosenbauer Compliance was informed that we had a delivered truck in Wisconsin (VIN M12904 / SN LRS01557102) that experienced a broken pinion and after some review, this truck was not part of the original recalled population. My team and I worked with Meritor to address the problem immediately through a local shop on Monday- Tuesday. Since this truck was not originally identified as part of the recall, both Meritor and Rosenbauer expressed concern. It was agreed that Meritor would review their bookends on production timeframe and potentially expand the population. On 3/9/22, Meritor’s quality manager reached out to Rosenbauer alerting them that the population had expanded and he sent a new list of additional trucks. Rosenbauer exchanged phone calls and emails trying to tie the Meritor Serial Number to our VIN around 3/16/22. On 3/21/22, Rosenbauer Compliance requested a meeting to discuss the plan as some are in Production but most are delivered; the meeting was held the next day. Meritor shared the missing information (PO info) and Rosenbauer tied those to the appropriate trucks by end of day 3/23/22. The population for the US went from 16 to 81 on 3/23/22. Rosenbauer also received the field campaign remedy plan, however, the plan to address the additional trucks in production would be further discussed on Monday 3/28/22. On 3/29/22, Rosenbauer started a draft amendment #2 in the NHTSA portal and reached out to a NHTSA representative asking if they should submit knowing that the population and remedy might change. In this email, there is an attachment from the Meritor rep that Rosenbauer has been communicating with stating that there was a delay on their part. All Dealers were alerted via an informal email on Wednesday 3/30/22 that more trucks will be involved in the recall and that details were to-be-determined. That same day, we started coordinating the replacement of the recalled carriers for 3 trucks that were at our Dealers prior to final customer delivery in attempt to remain compliance to the federal law of not delivering any recalled trucks to a customer. These remedies were completed in the next few days by an authorized Meritor service provider. Letters were started on 3/24/22 and sent to Meritor on 3/25/22 for review. Meritor replied on 3/30/22 with their edits that were questioned by Rosenbauer. Rosenbauer expressed at that time that the majority of our trucks had exposed air brake lines which was a stipulation for seeking the remedy. Questions were sent to Meritor on Monday 4/4/22. Meritor called Rosenbauer Compliance Manager on Tuesday 4/5/22 to say that ultimately that Rosenbauer can proceed with how they see fit. However, there was still confusion on how to process the remedy and what Meritor Service Department would need from our Customers and Dealers. After some discussion with Meritor and internally, Rosenbauer determined the proper remedy and documentation/claim process. This process will be detailed in our notification letters but ultimately there are two main things that identify if the axle will be remedied with a carrier replacement: mileage under 8496 (or 13672km) and exposed air brake lines. Meritor is stating that if the truck has more than 8496 miles/13672 km and has not faced any failures, it should not be inspected or remedied as their data states the pinion would have broken by now. Furthermore, Meritor is stating that the safety risk is due to the pinion’s proximity to the air brake lines. If the pinion breaks and can be sheltered from damaging the brake lines, then it will not be remedied with a carrier replacement. Instead it will go through their normal warranty and service claim process at the time of failure. Due to this, Meritor’s Ontrac system will request the customer provides the inservice date, current mileage and photos of the air brake lines near the rear axle. These details will be outlined in our notification letters. In that same phone call on 4/5/22, Meritor informed Rosenbauer that there will be additional trucks in the recall due to their analysis into their aftermarket sales department. They were expanding the production dates which will impact our population again. The risk for failure was still considered low but now we have more to remedy in Production and in the field. The following day on Wednesday 4/6/22, Rosenbauer received the entire population and started the analysis to identify which trucks received recalled axles; On 4/6/22, NHTSA contacted Rosenbauer regarding the 3/29/11 email. Suggestions to update the timeline/schedule, chronology, and remedy. Since Rosenbauer is still trying to figure out the exact population, this will be on hold and the draft was not submitted. Thursday 4/7/22 Rosenbauer asked for additional purchase order information to help identify which truck received which suspect carrier. Friday 4/8/22 Rosenbauer identified each and every new trucks involved in the recall as well as their physical location. Additional trucks were placed on ship hold; The necessary parties at Meritor and Rosenbauer were notified. As of 4/9/22, the population for US is 125 and includes 2020 Avengers, 2013, 2020-2022 Commanders, 2020-2022 Warriors. It was previously 81. Tuesday 4/12/22 Meritor Techs arrived onsite in SD to inspect (remedy as necessary) the trucks in South Dakota Production; All passed inspection. Monday 4/18/22, Meritor may be able to inspect two to four trucks that are located at our Nebraska plant due to the timing of their techs being in Nebraska. If this can’t happen, we will have another round of trucks to inspect at our SD plant. If that is our only option, the date on that inspection is to-be-determined. Monday 4/25/22 Meritor Techs can inspect the trucks in MN Production and our Chassis Production. A second amendment was submitted to NHTSA on 4/15/22 with the final remedy plan and schedule. Official Dealer Notifications will begin 4/18/22. Letters will be revised on 4/18/22 with the plan to print and mail them 5- 7 days after.

We started our analysis on the impacted trucks and identified where the impacted trucks are located and filed the appropriate paperwork for the recall. Rosenbauer asked for additional information from Meritor including the remedy for delivered trucks and trucks in production.

Tuesday 4/12/22 Meritor Techs arrived onsite in SD to inspect (remedy as necessary) the trucks in South Dakota Production; All passed inspection. Thursday 4/14/22, additional meeting with Meritor to discuss the field campaign and inspecting the trucks in production. The schedule will move out. Meritor expressed that the recall was launched and we could start notifications. Rosenbauer informed them of the population at our Dealers pending delivery to the customer and that we need to get these remedied soon. They agreed to support us. Friday 4/15/22: Rosenbauer informed those dealers that they can arrange for remedy on the trucks at their location prior to customer delivery as per federal law. A second amendment was submitted to NHTSA on 4/15/22 with the final remedy plan and schedule. Tuesday 4/19/22: Rosenbauer was informed by our Dealer that the impacted trucks and updated population were not updated in the Meritor OnTrac System so it showed that these were incorrectly not impacted by the recall. A follow-up meeting with Meritor occurred on Wednesday 4/20/22 to outline the schedule and finalize the details.  Tuesday 4/26/22: Meritor Techs will inspect the trucks in MN Production and our Chassis Production.  Wednesday 4/27/22: Meritor will inspect three trucks that are located at our Nebraska plant due to the timing of their techs being in Nebraska. If this can’t happen, we will have another round of trucks to inspect at our SD plant. If that is our only option, the date on that inspection is to-be-determined and possibly will entail Rosenbauer taking the truck to the local Freightliner dealership to have the carrier replaced. TBD.  Meritor needs to get their call center crews up to speed to address the influx of calls and emails to OnTrac due to this recall. They did not get their systems updated even though they were notified on April 8.  They won’t have this updated until Friday 4/22/22. Some of the claims for trucks at Dealers that are awaiting customer delivery have been able to get attention via our contacts at Meritor. Additionally, Meritor’s former Compliance Manager who helped file this recall was on the 4/20/22 call for any questions regarding the filing. After some discussion, Rosenbauer was informed that the 21E-098 Recall from Meritor is not in fact, for all OEMs that receive Meritor product and that 21E-098 is for REV group only and was filed from a compliance standpoint, not a safety risk. It is Meritor’s response to the REV group’s filing. This was not communicated when Rosenbauer was notified of the recall via a meeting with Meritor reps in January. The recent recall that was recently filed by Meritor, Recall # 22E-027 only applies to the aftermarket sale of axles which is not what Rosenbauer partakes in, therefore this recall is also not applicable to our product. At this time, Meritor is unsure if they will file a recall related to Rosenbauer’s fire trucks. Friday 4/22/22: Rosenbauer uploaded draft letters and communications on NHTSA portal. Monday 4/25/22 Meritor Techs start inspecting the trucks in MN Production and our Chassis Production. 2 fail; coordinating with Meritor and local shop to replace carriers. Tuesday 4/26/22: Noting that it seems to be taking longer than expected to receive the recall determination from Meritor, Rosenbauer reached out to Meritor about what we can expect for turnaround times so we can include that in our letters. The whole process could take 5-10 business days: 1-3 days to process claims, analyze the photos and respond, 2-3 days to build replacement carriers and then transit time (1-5 days). Due to this timing being inconsistent, Rosenbauer will continue to monitor claims that are being processed for trucks that are at our Dealers, pre-delivery as we are concerned that Meritor may not be able to keep up with the influx of claims. Final drafts were uploaded 4/27/22 with this additional information; Dealers were emailed official letters and list of trucks on 4/28/22. Official Owner Letters were sent to the print shop 4/27/22. Letters for NHTSA were mailed 5/4/22. Wednesday 4/27/22 Meritor Techs inspect 3 trucks in NE; 1 fails and needs replacement carrier. Coordinating with Meritor and local authorized shop to do the work. Chronology and schedule updated on NHTSA portal 5/6/22. As of 5/5/22, Rosenbauer continues to work with Meritor to remedy trucks prior to shipment and customer delivery. We still have a few that may need replacement carriers in Production and they will not leave Rosenbauer until resolved.

Rosenbauer Recall # 22V-025 Page | 1 IMPORTANT SAFETY RECALL Owner Attention: Fire Chief Address City, State, Zip, Country VIN: Axle SN: Axle Model #: Meritor 180 Series April 22, 2022 Re: Safety Recall Notice NHTSA Recall ID# 22V-025 Dear Owner of a Rosenbauer Fire Apparatus: This notice is sent to you in accordance with the requirements of the National Traffic and Motor Vehicle Safety Act. This is to inform you that your vehicle may have a safety-related defect that could result in a vehicle crash. Federal law requires the Recall Remedy completed on this unit prior to customer delivery. What is the issue? Rosenbauer America is recalling certain Fire Trucks equipped with a Meritor 180 Series Rear Axle manufactured beween November 2020 and March 2022; to include: 2020 Avengers, 2020-2022 Commanders and 2020- 2021 Warriors. The axles installed on these trucks may have a defect in the rear axle drive pinion that could cause it to fracture. If this happens, the air brake lines that are routed in the proximity of the driveline could be damaged, and if sufficiently ruptured could cause the parking brakes to apply unexpectedley and without the brake lights illuminating appropriately. Brake lights that do not illuminate when the parking brake self-applies while driving could increase the risk of a crash. The driver may hear an audible noise and feel the vehicle slow down due to propulsion from the drive axle. Please exercise caution and safely get to the side of the road if this happens. How do I know if my truck has this type of equipment? Rosenbauer worked with Meritor to identify the potentially impacted trucks based on the axle series and carrier build dates. If you are receiving this letter, your vehicle may be impacted by this recall. We first ask that you check your vehicle’s mileage and follow these instructions:  If the mileage is above 8,496 miles /13,672 kilometers , you will need to write the mileage down on the postcard provided in this letter along with your customer and truck information and send it back to Rosenbauer (postage and address supplied on postcard). o You will not need to do anything further with this recall and once we have received your postcard, we will remove your truck from our population.  If the mileage is below 8,496 miles / 13,672 kilometers , you will need to follow the instructions in the next section. How do I resolve this important safety recall? We are recommending that you call your local Commercial Truck Repair Facility that is an authorized Meritor repair facility (i.e. Freightliner, Kenworth, etc) to initiate the next steps. In order for them to best serve you, you will need to provide the following 8 pieces of information : 1. Full VIN Number (per top of this letter) 2. Axle Model Number (per top of this letter) 3. Axle Serial Number (per top of this letter) 4. Your truck’s in-service date 5. Your vehicle mileage 6. Rosenbauer’s recall number 22V-025 7. Your contact information 8.

Rosenbauer Recall # 22V-025 Page | 1 IMPORTANT SAFETY RECALL Attention: Dealer Name 04/22/20222 Re: Safety Recall Notice NHTSA Recall ID# 22V-025 Dear Rosenbauer Dealer: This notice is sent to you in accordance with the requirements of the National Traffic and Motor Vehicle Safety Act. This is to inform you that a vehicle in your network may have a safety-related defect that could affect the safety of a person. Federal law requires the Recall Remedy completed on this unit prior to customer delivery. If there are any units in your posession at the time you have received this letter, please contact us. Owner notification letters will be in the next 7 days. What is the issue?: Rosenbauer America is recalling certain Fire Trucks equipped with a Meritor 180 Series Rear Axle manufactured beween November 2020 and March 2022; to include: 2020 Avengers, 2020-2022 Commanders and 2020- 2021 Warriors. The axles installed on these trucks may have a defect in the rear axle drive pinion that could cause it to fracture. If this happens, the air brake lines that are routed in the proximity of the driveline could be damaged, and if sufficiently ruptured could cause the parking brakes to apply unexpectedly and without the brake lights illuminating appropriately. Brake lights that do not illuminate when the parking brake self-applies while driving could increase the risk of a crash. The driver may hear an audible noise and feel the vehicle slow down due to propulsion from the drive axle. Please exercise caution and safely get to the side of the road if this happens. What we are asking the customers to do: Due to the complexity of this recall, we have detailed instructions on how our customers will navigate the next steps to help determine and then resolve the recall.  If the mileage is above 8,496 miles (13,672 km), the customer does not need to seek the recall remedy due to Meritor’s research. However, we will need to know if that is the case so we are asking for postcards back.  If they have below 8,496 miles (13,672 km), they will need to contact their local authorized Meritor service provider to file the claim. To initiate the request, they will submit 8 pieces of information to their repair facility including photos of their brake lines in relation to the rear axle and driveline since that close proximity is dictating that a remedy is required.  Meritor will inform the repair shop the decision so they can either move forward with securing a repair kit to replace the carrier or complete the warranty claim even if a repair isn’t sought due to the requirements listed above.  We recommend contacting the local Commercial Chassis Dealer (Freightliner, IH, etc) ahead of time to ensure they are an authorized Meritor service provider and that repair shop files a claim with Meritor directly.  We are asking for postcards back with this information and will submit SRS tickets as we receive them.  For ease, we have included the customer’s how-to-resolve details on Page 3. What do we need from our dealers? If you are submitting claims and performing the remedy as an authorized Meritor service provider, we will ask you to submit an SRS ticket in case the customer does not send us a completed postcard. We also ask that you ensure you can file claims through Meritor’s OnTrac System. More information can be found on meritor.com/warranty, by emailing ontrac@meritor.com or calling 1-866-668-7221. Additionally, it is important that any repair shop helping the customer with their recall are authorized with Meritor ahead of time and can file claims directly. Rosenbauer Recall # 22V-025 Page | 2 Please note that we estimate the repair will take 6 hours since it involves a carrier replacement. We are asking customers and dealers to schedule accordingly. All repairs will be provided to the customers free of charge . What if the customer already paid to have this repair completed? The customer should contact Rosenbauer or their Dealer with the details of the repair and they will receive reimbursement. If you performed the repair, make sure to file directly with Meritor and submit an SRS ticket. What if the customer listed no longer owns this truck ? The Dealer or customer should contact Rosenbauer to provide the new owner information. Rosenbauer will then contact the new owner.

I will be in contact with each Dealer if that doesn’t happen soon enough.  Until we figure out the plan to fix trucks in the field, please alert us if any drivers hear an audible noise and feel the vehicle slowing down due to loss of propulsion. We can check if that truck is on the recall list.  More info is in the attached form. 2 Feel free to reach out should you have any questions regarding recalls or technical service bulletins at recalls@rosenbaueramerica.com.

Recall ID 22V-025 Page | 1 UNOFFICIAL DETAILS April 14, 2022 Re: Inspection / Remedy for Pre-Delivery Trucks Prior to Recall Launch 22V-025 Thank you for your help in resolving the recall of this fire truck prior to delivery. We will send an official notification letter to you and the customer in the next 7-10 days regarding the rest of the trucks in this recall. However, federal law requires the recall remedy be completed on all recalled trucks prior to customer delivery. What is the issue: Rosenbauer America is recalling certain Rosenbauer Chassis that have the Meritor 180 Axle identified by Meritor. The axle may have a defect in the rear axle drive pinion that could cause it to break. If this happens, the air brake line could be damaged and cause the parking brakes to engage suddenly and unexpectedly. It is possible that when this happens, the brake lights will not function due to the severing of brake line and loss to system air pressures. This is a safety risk. How to remedy trucks during Pre-Delivery Inspection: We are recommending that you call your local Commercial Truck Repair Facility that is an authorized Meritor repair facility (i.e. Freightliner, Kenworth, etc) to initiate the inspection and/or remedy of the recalled carrier. If for some reason, you can not find an authorized Meritor repair facility, you or your local shop can seek authorization by contacting Meritor Ontrac and submitting their W9. Once you have located a repair facility, you will need to provide the following 7 pieces of information:  Full VIN  Axle Model # Meritor 180 Series  Axle Serial Number (found in my email)  The vehicle mileage  Rosenbauer’s recall number 22V-025  Your contact information  A photo of the air brake lines (similar to page 2). The Repair Facility will open a case with Meritor’s OnTrac Technical Call Center and will use this information to verify that the truck is part of the campaign population. Meritor will order the replacement parts (Carrier with Driveline Yoke, Carrier to Housing Kit, and replacement Driveline fastener kits) to be shipped to the repair facility free of charge. The Repair Facility will then call you when the parts arrive. Please note that we estimate the repair will take 6 hours. Next Steps: Please complete an SRS ticket with the name of the repair facility that completed the inspection and/or repair, the date of service, the results of service and the photos you sent in. Please contact Rosenbauer America if for some reason you have any issues. We are here to support you in resolving this recall prior to delivery.

We have also included a list of the trucks impacted in your network. Due to the complexity of this recall, we have included the exact wording we are giving the customers which mirrors some of the details provided to you.  Claims will be filed directly to Meritor from the authorized Meritor service provider that the customer chooses.  In order to file a claim, the customer must provide critical information like VIN, Axle SN, the vehicle’s mileage and photos of the rear axle area at the time they call their repair shop to initiate the claim.  The service provider will take this information and submit it to Meritor’s OnTrac system. Authorized Meritor service providers should be familiar with this process. If you are performing the claim and remedy work and have any questions, feel free to reach out.  Meritor will review the information/photos and decide if the truck requires the remedy or if the truck is exempt. The review process should take 3 days. Replacement carriers can be shipped in 2-3 day, not including transit times.  Finally, Rosenbauer is requesting notification of either events and are asking the customer to mail the postcard back to us included in their letter. This will help us retain record retention as required by the government. We will enter SRS tickets as we receive the postcards. I’m always available for any questions.

Production Dates : JAN 25, 2021 – JAN 21, 2022 VIN Range 1 : Begin : 54F2FBCL9MWM12934 End : 54F8JECH9MWM12938 ✔ Not sequential Part 573 Safety Recall Report 22V-025 Page 2 The information contained in this report was submitted pursuant to 49 CFR §573 Description of Defect : Description of the Defect : The drive pinion is possibly suspectible to fracturing due to the pinion and yoke spline interacting which may result in an overstress condition. The fracture of the pinion may hit the brake drop hose which may unintentionally apply the parking brake without detection or brake lights coming on, possibly resulting in a crash. FMVSS 1 : NR FMVSS 2 : NR Description of the Safety Risk : A fractured drive pinion may contact the brake drop hose and unintentionally engage the parking brake without detection or without the brake lights activating, increasing the risk of a crash. Description of the Cause : Meritor is still investigating but it could be due to the pinion and yoke spline interaction during the assembly process. Identification of Any Warning that can Occur : The driver may hear an audible noise and feel the vehicle slowing down due to loss of propulsion from the drive axle should the pinion fracture. Involved Components : Component Name 1 : Rear Axle Carrier Component Description : Pinion 180 Series Component Part Number : NR Supplier Identification : Component Manufacturer Name : Meritor Address : NR NR Country : NR Chronology : On January 5, 2022 Rosenbauer was alerted in a meeting that we had recalled product from Meritor. Rosenbauer is in the process of locating all the impacted trucks and will reach out to Meritor for remedy trucks in Production prior to shipment. All but one truck identified to be in production was inspected and remedied by Meritor the week of 2/14/22 at Rosenbauer’s facilities. There is one final truck that once complete at our Part 573 Safety Recall Report 22V-025 Page 3 The information contained in this report was submitted pursuant to 49 CFR §573 Nebraska location, will travel back to SD and receive the inspection and remedy. On 3/9/22, Meritor’s quality manager reached out to Rosenbauer alerting them that the population has expanded and he sent a new list of additional trucks. As of 3/21/22, we still have not decided on how to fix these trucks and Rosenbauer and Meritor will meet to discuss the plan as some are in production but most are delivered. Description of Remedy : Description of Remedy Program : Rosenbauer will provide the remedy at free of charge to our customers and dealers. We will work with Meritor on any reimbursement. As of March 21, 2022, the final remedy is not solidified with Meritor and I have requested a meeting to discuss further. One option is to have the customers take their truck to a Meritor-approved service provider and that service provider can replace the carrier. However, I am unsure if parts will be available so the customer will need to plan ahead. How Remedy Component Differs from Recalled Component : Unknown at this time. Identify How/When Recall Condition was Corrected in Production : We are in the process of working with Meritor on a remedy and applying that to trucks in Production. The trucks in production were tested by a Meritor representative using an ultrasonic test machine. We had 2 failures that were remedied by a local approved Meritor service provider who replaced the carriers provided by Meritor. TBD how the additional trucks will be remedied. Recall Schedule : Description of Recall Schedule : Rosenbauer will notify customers and dealers within 60 days of today. We will alert our dealers with an informal notification via email if we have trucks in the field that are impacted. We may have to send an interim letter to our customers if we can not identify the remedy in time.

Description of Remedy : Description of Remedy Program : Rosenbauer will provide the remedy at free of charge to our customers and dealers. We will work with Meritor on any reimbursement. We will advise the customer and dealers to check their truck’s mileage and if it’s above 8496 miles, they can call ahead to their local Meritor authorized repair facility (that is typically a Kenworth, Freightliner, Commercial Truck dealer) to schedule the repair. They will need to provide some pertinent information like VIN, serial numbers, model numbers and mileage so that the repair facility can coordinate getting parts from Meritor to replace the carrier. They will also be asked to provide a photo of the air brake lines in proximity to the rear axle. Meritor or the repair shop will review the photos for exposure to a potentially fractured pinion and decide if a fracture could be sheltered from puncturing the brake lines and therefore eliminating the safety risk. Once the remedy is scheduled and complete, the customer will notify Rosenbauer by mailing us a prepaid posted postcard with the pertinent information. If the mileage is less than 8496 miles, they will need to notify Rosenbauer of the mileage and that they did not seek the remedy per our instructions. Any and all repairs will be provided to the customers free of charge. The repair shop who performs the remedy will file a claim directly to Meritor via their ontrac system. Part 573 Safety Recall Report 22V-025 Page 5 The information contained in this report was submitted pursuant to 49 CFR §573 How Remedy Component Differs from Recalled Component : The replaced carrier and parts will be from properly assembled and inspected product passing Meritor’s additional QC inspections. Identify How/When Recall Condition was Corrected in Production : Rosenbauer will continue to work with Meritor and Dealers to remedy the trucks in production prior to customer delivery. If the truck is already at the Dealer for Pre-Delivery Inspection, the Dealer will seek the remedy which is the same process that will be in our notification letters. Recall Schedule : Description of Recall Schedule : Rosenbauer will start officially notifying Dealers on Tuesday April 19, 2022 with a list of their impacted trucks. At that time, owner notification letters will be revised with the new remedy details and then printing can start on Wednesday April 20, 2022 with the intent that letters are mailed to customers 7 days later. Rosenbauer realizes that this is more than 60 days after notification were due to the customers and that an interim letter should have been mailed. We were still working on the details with Meritor and they were solidified Thursday 4/14/22. We will work to rectify the problem within our systems to ensure that we can streamline interim notifications.
