Frequently Asked Questions (FAQs)
1. Why is Daimler Truck North America (DTNA) issuing this recall (FL-958)?
On certain vehicles, chemical corrosion could affect the functionality of the brake modulator valve, which during an Adaptive Cruise Control (ACC) braking event may result in full system pressure applied to one wheel end causing brake pull from differential in brake force. Regular service brakes are unaffected
A full system pressure applied to one wheel end could lead to a brake pull resulting in a sudden change in vehicle direction due to uneven braking on the front axle increasing the risk of a motor vehicle crash.
2. Which vehicles are included in this recall (FL-958)?

7. Why did the previous recall (FL-855) not address the issue described in this recall (FL-958)?
In 2020, Daimler Truck North America (DTNA) recalled unpainted brake modulator valves due to possible corrosion and implemented a remedy of painted valves (described in FL-855). Following two reports of vehicle pull during Adaptive Cruise Control (ACC) operation from a customer with the painted valves in September 2022, DTNA worked with this and other customers to randomly select additional painted valves to inspect. Testing results revealed varying degrees of corrosion build up on the valves installed on trucks and was most present on vehicles primarily operating in aggressive salt belt regions. Thus, DTNA initiated this new recall (FL-958) to replace painted brake modulator valve with anodized valves on the vehicles equipped with ACC
8. When and how will customers be notified of this recall (FL-958)?

Chronology :
In 2020, DTNA recalled unpainted brake modulator valves due to possible corrosion and implemented a remedy of painted valves.
On September 14, 2022, DTNA received two reports of vehicle pull during an Adaptive Cruise Control (ACC) event from a single isolated customer with the painted valves. The first report mentioned about two cases of unintended brake pull to the left side, while the second mentioned one case of unintended brake pull to the right side.
The dealer was able to isolate the failure to the painted steer single modulator valve after repairing the vehicle. The reports all center around vehicles from one limited geographic area. In or around that time, DTNA promptly opened an investigation to determine the scope of the issue.
Additionally, DTNA promptly analyzed the failed parts and found debris associated with corrosion. Around the same time, DTNA conducted a warranty seek and was unable to find claims alleging brake pull events caused by subject valve corrosion.
However, as part of its due diligence, DTNA worked with customers in various locations starting in early October 2022 to randomly select parts to inspect.
36 valves were returned from various parts of the east salt belt region in Canada and the United States and shipped to the supplier for further evaluation.
Corrosion testing results on 5 trucks (2 different customers) found through late October 2022 revealed varying degrees of corrosion build up on the valves installed on trucks operating in the aggressive salt belt region of South East Canada (Quebec). Around the same time, DTNA received corrosion testing results on valves installed on trucks based in the US’s aggressive salt belt region (Maine and New York), and there was some level of corrosion found.
On or about late October and early November, DTNA decided to recall in Canada where corrosion was first observed and then in the US where less severe corrosion was later found.

Defect Information Report (Section 573.6) FL-958 Date of Submission: November 1, 2022 Manufacturer: Daimler Truck North America LLC P.O. BOX 3849 Portland, Oregon 97208 Type of Report: X Safety Defect Non-Compliance Vehicle Information Model Yr. Start: 2017 Model Yr. End: 2023 Make: Freightliner Model: Cascadia Production Dates: Begin: 03/08/2016 End: 06/18/22 Type: Truck/Tractor Descriptive Information: Only certain Cascadia vehicles equipped with painted modulator valves and Adaptive Cruise Control (ACC) technology are included in this recall. Number potentially involved: 217,468 Estimated percentage of involve with defect: N/A Defect Description Describe the defect: On certain vehicles, chemical corrosion could affect the functionality of the brake modulator valve, which during an Adaptive Cruise Control (ACC) braking event may result in full system pressure applied to one wheel end causing brake pull from differential in brake force. Regular service brakes are unaffected. If a noncompliance, provide the applicable FMVSS: N/A Describe the safety risk: A full system pressure applied to one wheel end could lead to a brake pull resulting in a sudden change in vehicle direction due to uneven braking on the front axle increasing the risk of a motor vehicle crash. Identify any warning, which can precede or occur: Driver’s may get an ABS light prior to complete valve contamination. If applicable, identify the manufacture of the defective or noncompliant component: Braking System Involved Components Component Name: Single ABS Modulator Valve Component Description: Quick Release Pneumatic Valve Component Part Number: WAB472 196 037 0, WAB472 196 025 0 Supplier Identification: ZF CV Systems North America LLC 1220 Pacific Dr Auburn Hills, MI, 48326 USA Daryl Sinclair Head of Field Quality and Customer Service Mobile +1 (248) 807 7561 daryl.sinclair@zf.com Component Manufacturer: ZF CV Systems North America LLC Chronology of Noncompliance Determination Provide the chronology of events leading up to the defect decision or test data for the noncompliance decision. In 2020, DTNA recalled unpainted brake modulator valves due to possible corrosion and implemented a remedy of painted valves. On September 14, 2022, DTNA received two reports of vehicle pull during an Adaptive Cruise Control (ACC) event from a single isolated customer with the painted valves. The first report mentioned about two cases of unintended brake pull to the left side, while the second mentioned one case of unintended brake pull to the right side. The dealer was able to isolate the failure to the painted steer single modulator valve after repairing the vehicle. The reports all center around vehicles from one limited geographic area. In or around that time, DTNA promptly opened an investigation to determine the scope of the issue. Additionally, DTNA promptly analyzed the failed parts and found debris associated with corrosion. Around the same time, DTNA conducted a warranty seek and was unable to find claims alleging brake pull events caused by subject valve corrosion. However, as part of its due diligence, DTNA worked with customers in various locations starting in early October 2022 to randomly select parts to inspect. 36 valves were returned from various parts of the east salt belt region in Canada and the United States and shipped to the supplier for further evaluation. Corrosion testing results on 5 trucks (2 different customers) found through late October 2022 revealed varying degrees of corrosion build up on the valves installed on trucks operating in the aggressive salt belt region of South East Canada (Quebec). Around the same time, DTNA received corrosion testing results on valves installed on trucks based in the US’s aggressive salt belt region (Maine and New York), and there was some level of corrosion found. On or about late October and early November, DTNA decided to recall in Canada where corrosion was first observed and then in the US where less severe corrosion was later found. As DTNA moved quickly to determine a recall, some facts remain unknown. DTNA is continuing to investigate the impact of other external braking events, such as Electronic Stability Control (ESC) and Anti-lock Braking System (ABS). Identify the Remedy Describe the defect/noncompliance remedy program, including the manufacture’s plan for reimbursement. Affected vehicles will receive an anodized valve. Repairs will be released in phases based on locations of the vehicle and repairs will be performed by Daimler Trucks North America authorized service facilities. Customer notification will be done by first class mail using Daimler Trucks North America records to determine the customers affected. Daimler Truck North America shall be offering a refund for owner-paid repairs covered by this recall if the repair was performed prior to the date indicated in the reimbursement plan, which will be posted with owner’s notification letter. Owners are directed to seek reimbursement through authorized deal. Identify the Recall Schedule Describe the recall schedule for notifications: Customer notification will be made by first class mail using Daimler Trucks North America records to determine the customers affected.

The DIR was updated on November 9, 2022 by DTNA to include the most accurate affected population based on the best-known registration domicile location and the best-known supplier identification information. On September 25, 2023 DTNA updated the description of the remedy campaign to reflect prioritization of repairs for vehicles currently registered in certain states where road salt is regularly used in the winter.

Frequently Asked Questions (FAQs) 1. Why is Daimler Truck North America (DTNA) issuing this recall (FL-958)? On certain vehicles, chemical corrosion could affect the functionality of the brake modulator valve, which during an Adaptive Cruise Control (ACC) braking event may result in full system pressure applied to one wheel end causing brake pull from differential in brake force. Regular service brakes are unaffected A full system pressure applied to one wheel end could lead to a brake pull resulting in a sudden change in vehicle direction due to uneven braking on the front axle increasing the risk of a motor vehicle crash. 2. Which vehicles are included in this recall (FL-958)? Model year 2017-2023 Freightliner New Cascadia vehicles (237,316 vehicles), Model Year 2020-2022 Freightliner Business Class M2s (23 vehicles) , Model Year 2020-2023 Western Star 49X (746 vehicles) , Model Year 2021-2022 Western Star 47X (32 vehicles), Model Year 2021-2022 Western Star 57X (17 vehicles), manufactured by Daimler Truck North America (DTNA) between March 8, 2016 and June 18, 2022 and equipped with Adaptive Cruise Control (ACC) technology and painted modulator valves are included in this recall. 3. How do I determine if a vehicle is included in this recall (FL-958)? As required, DTNA will issue owner notifications on or before 12/30/22 to inform customers about the recall remedy, population, and unreasonable safety risk associated with the issue. Model year 2017-2023 Freightliner New Cascadia vehicles (237,316 vehicles), Model Year 2020-2022 Freightliner Business Class M2s (23 vehicles) , Model Year 2020-2023 Western Star 49X (746 vehicles) , Model Year 2021-2022 Western Star 47X (32 vehicles), Model Year 2021-2022 Western Star 57X (17 vehicles), manufactured by Daimler Truck North America (DTNA) between March 8, 2016 and June 18, 2022 and equipped with Adaptive Cruise Control (ACC) technology and painted modulator valves are included in this recall. Also, vehicles recalled under FL-855 that are equipped with Adaptive Cruise Control (ACC) will require new anodized steer modulator valves and will be covered under FL-958. Repairs will be released in phases based on locations of the vehicle, and repairs will be performed by Daimler Truck North America’s authorized service facilities. 4. Who will pay for repairs? Daimler Truck North America (DTNA) will perform the recall remedy free of charge. 5. How quickly can Daimler Truck North America satisfy the recall campaign? Daimler Truck North America (DTNA) currently has limited stock and is working with its supplier to quickly ramp-up production of additional supply. Repairs will be released in phases based on age and operating locations of the vehicle. 6. Does this recall (FL-958) nullify the previous recall (FL-855)? This recall (FL-958) does not nullify the earlier recall (FL-855) and vehicles subject to both recalls will be reviewed when brought to an authorized service facility for the appropriate remedy or remedies. 7. Why did the previous recall (FL-855) not address the issue described in this recall (FL-958)? In 2020, Daimler Truck North America (DTNA) recalled unpainted brake modulator valves due to possible corrosion and implemented a remedy of painted valves (described in FL-855). Following two reports of vehicle pull during Adaptive Cruise Control (ACC) operation from a customer with the painted valves in September 2022, DTNA worked with this and other customers to randomly select additional painted valves to inspect. Testing results revealed varying degrees of corrosion build up on the valves installed on trucks and was most present on vehicles primarily operating in aggressive salt belt regions. Thus, DTNA initiated this new recall (FL-958) to replace painted brake modulator valve with anodized valves on the vehicles equipped with ACC 8. When and how will customers be notified of this recall (FL-958)? Customer notification will be made by first class mail using Daimler Truck North America records to determine the customers affected. The start of planned customer and dealer notifications is on or before December 30, 2022. 9. When will customers be able to schedule their repairs? Following notification by Daimler Truck North America (DTNA), customers and authorized service facilities, can coordinate repair schedules. 10. Why is the issue described in this recall (FL-958) present only when vehicles are utilizing Adaptive Cruise Control (ACC)? ACC events are affected based on the best and most recent understanding. DTNA is still investigating potential effects on other vehicles. DTNA is continuing to assess the impact on other export populations that have valves mounted differently than the originally recalled vehicles. 11. Do the brake modulator valves being changed carry a new part number from the previous painted version? Yes, the former, painted front axle brake modulator vales now being substituted for anodized valves carry distinct part numbers for the replacement parts. WAB472 196 025 0 – Unpainted valves were recalled in accordance with FL-855. WAB472 196 037 0 – Painted valves were used as a remedy to address that recall. Cascadia P4s equipped with Adaptive Cruise Control (ACC), the solution for recall FL-855 that is WAB472 196 037 0, will be replaced with WAB472 196 046 0 -Anodized valves as part of FL-958. 12. What supplier provided the affected brake modulator valves? The painted brake modulator valves described in this recall (FL-958) were manufactured by ZF CV Systems North America LLC and installed on Model year 2017-2023 Freightliner New Cascadia vehicles (237,316 vehicles), Model Year 2020-2022 Freightliner Business Class M2s (23 vehicles) , Model Year 2020-2023 Western Star 49X (746 vehicles) , Model Year 2021-2022 Western Star 47X (32 vehicles), Model Year 2021-2022 Western Star 57X (17 vehicles), manufactured by Daimler Truck North America (DTNA) between March 8, 2016 and June 18, 2022 13. Do my vehicles need to be parked until repairs are completed? Daimler Truck North America (DTNA) has not issued a do not drive order associated with this recall (FL-958) as regular service brakes are unaffected and the reported incidence rate of brake pull is extremely low. 14. What is the expected financial impact to DTNA for completing this (FL-958) recall campaign? Daimler Truck North America (DTNA) won’t disclose the financial impact of this (FL-958) or any other recall.

On September 14, 2022, DTNA received two reports of vehicle pull during an Adaptive Cruise Control (ACC) event from a single isolated customer with the painted valves. The first report mentioned about two cases of unintended brake pull to the left side, while the second mentioned one case of unintended brake pull to the right side. The dealer was able to isolate the failure to the painted steer single modulator valve after repairing the vehicle. The reports all center around vehicles from one limited geographic area. In or around that time, DTNA promptly opened an investigation to determine the scope of the issue. Additionally, DTNA promptly analyzed the failed parts and found debris associated with corrosion. Around the same time, DTNA conducted a warranty seek and was unable to find claims alleging brake pull events caused by subject valve corrosion. However, as part of its due diligence, DTNA worked with customers in various locations starting in early October 2022 to randomly select parts to inspect. 36 valves were returned from various parts of the east salt belt region in Canada and the United States and shipped to the supplier for further evaluation. Corrosion testing results on 5 trucks (2 different customers) found through late October 2022 revealed varying degrees of corrosion build up on the valves installed on trucks operating in the aggressive salt belt region of South East Canada (Quebec). Around the same time, DTNA received corrosion testing results on valves installed on trucks based in the US’s aggressive salt belt region (Maine and New York), and there was some level of corrosion found. On or about late October and early November, DTNA decided to recall in Canada where corrosion was first observed and then in the US where less severe corrosion was later found.
