Chronology :
February 2020, DTNA began an investigation to review all its features related to ABA events as part of a study to develop systems for new trucks. During this study, it was identified that certain features may need further review to ensure the current product met the provisions of FMVSS 108. March 2020 through April 2020, Product Validation conducted tests on certain vehicles to identify any potential non-compliance, and an extensive engineering investigation was undertaken to understand all the features of ABA and how they interact together. During this study, it was identified that in certain situations the hazard warning signals flash at a rate of 140 flashes per min. An in-depth review of NHTSA regulations and interpretations related to this issue indicated a potential non-compliance with the flash rate provisions. May 6, 2020, DTNA determined that a non-compliance existed as to the flash rate for the hazard warning lamps and decided to file a Part 573 noncompliance information report and petition for exemption from the notice and remedy provisions of the Safety Act for this issue. DTNA believed that this non-compliance was inconsequential as it relates to motor vehicle safety, as the occurrence is extremely rare, for a very short duration and does not contribute to confusion or distraction for other motorists. DTNA also recognized that the hazards automatically flash in severe brake events but deemed this not a non-compliance, nor an issue that needed NHTSA approval, based upon the permission granted to GM in essentially similar situations.
June 4, 2020, DTNA filed a petition for exemption from notification and remedy provisions of motor vehicle safety act for non-compliance with FMVSS no. 108, lamps, reflective devices and associated equipment. Between early June 2020 to Late July 2020, DTNA communicated with NHTSA, at the agency’s request, regarding DTNA’s non-compliance information report and inconsequentiality petition.

Defect Description
Describe the defect:
On the affected vehicles, during certain Advanced Brake Assist (ABA) events that have progressed to require a full emergency brake application to avoid a collision, the hazard warning lights may activate automatically in the moments immediately before the vehicle comes to a complete stop and flashes at a rate of 140 flashes per min. FMVSS 108, requires the hazard warning signal lights to be driver controlled and flashing rate to be between 60-120 flashes per min and that the activation of the hazard warning operating unit be “driver controlled.”
If a noncompliance, provide the applicable FMVSS: FMVSS 108
Describe the safety risk:
Certain Freightliner Cascadias with DTNA’s ABA system will automatically activate the hazard lamps if the vehicle’s safety system engages in extreme evasive braking, which can increase the risk of a crash for other road users. NHTSA considers the automatic hazard activation in these circumstances, as well as the flash rate at which the hazard lamps’ flash rate, noncompliance under FMVSS 108 Lamps, reflective devices, and associated equipment.
Identify any warning, which can precede or occur: ABA events which progress to a full emergency braking stage occurs only after multiple warnings to the driver including auditory and visual warnings, haptic braking which involves partial braking along with auditory and visual warnings.

Component Manufacturer: DTNA
Chronology of Noncompliance Determination
Provide the chronology of events leading up to the defect decision or test data for the noncompliance decision.
February 2020, DTNA began an investigation to review all its features related to ABA events as part of a study to develop systems for new trucks. During this study, it was identified that certain features may need further review to ensure the current product met the provisions of FMVSS 108. March 2020 through April 2020, Product Validation conducted tests on certain vehicles to identify any potential non-compliance, and an extensive engineering investigation was undertaken to understand all the features of ABA and how they interact together. During this study, it was identified that in certain situations the hazard warning signals flash at a rate of 140 flashes per min. An in-depth review of NHTSA regulations and interpretations related to this issue indicated a potential non-compliance with the flash rate provisions. May 6, 2020, DTNA determined that a non-compliance existed as to the flash rate for the hazard warning lamps and decided to file a Part 573 non-compliance information report and petition for exemption from the notice and remedy provisions of the Safety Act for this issue. DTNA
believed that this non-compliance was inconsequential as it relates to motor vehicle safety, as the occurrence is extremely rare, for a very short duration and does not contribute to confusion or distraction for other motorists. DTNA also recognized that the hazards automatically flash in severe brake events but deemed this not a non-compliance, nor an issue that needed NHTSA approval, based upon the permission granted to GM in essentially similar situations.
June 4, 2020, DTNA filed a petition for exemption from notification and remedy provisions of motor vehicle safety act for non-compliance with FMVSS no. 108, lamps, reflective devices and associated equipment. Between early June 2020 to Late July 2020, DTNA communicated with NHTSA, at the agency’s request, regarding DTNA’s non-compliance information report and inconsequentiality petition. DTNA made several verbal updates, presentations and provided evidence and data to support the inconsequentiality petition pertaining to hazard warning signals flashing at 140 flashes per min during certain ABA events that involves full braking. July 13, 2020, upon NHTSA’s request, DTNA amended the inconsequentiality petition to include FMVSS S14.9.3.9.3 – flasher performance requirements as an additional non-compliance basis. Between late August 2021 to late December 2021, DTNA again reviewed the inconsequentiality petition with NHTSA at the agency’s request, culminating in an amendment to the Part 573 non-compliance information report and petition for exemption.
On March 20, 2023, DTNA received notice of denial of the inconsequentiality petition for noncompliance. Therefore, out of abundance of caution, and per the requirements of Motor Vehicle Safety Act, DTNA submitted a new Part 573 report in light of the agency’s response.
Identify the Remedy
Describe the defect/noncompliance remedy program, including the manufacture’s plan for reimbursement.
On the affected vehicles, parameters controlling the enablement of hazards flashing automatically at a faster frequency during an ABA Emergency Braking Event will be disabled. Customer notification will be done by first class mail using Daimler Truck North America records to determine the customers affected. Repairs will be performed free of charge by Daimler Truck North America authorized service facilities. Details of the reimbursement plan will be included in the owner’s notification letter.

Defect Description
Describe the defect:
On the affected vehicles, during certain Active Brake Assist (ABA) events that have progressed to require a full emergency brake application to avoid a collision, the hazard warning lights and headlamps may activate automatically in the moments immediately before the vehicle comes to a complete stop and hazards flashes at a rate of 140 flashes per min. FMVSS 108, requires the hazard warning signal lights to be driver controlled and flashing rate to be between 60-120 flashes per min and that the activation of the hazard warning operating unit be “driver controlled.”
If a noncompliance, provide the applicable FMVSS: FMVSS 108
Describe the safety risk:
On certain vehicles with DTNA’s ABA system will automatically activate the hazard lamps if the vehicle’s safety system engages in extreme evasive braking, which can increase the risk of a crash for other road users. NHTSA considers the automatic hazard activation in these circumstances, as well as the flash rate at which the hazard lamps’ flash rate, noncompliance under FMVSS 108 Lamps, reflective devices, and associated equipment.
Identify any warning, which can precede or occur: ABA events which progress to a full emergency braking stage occurs only after multiple warnings to the driver including auditory and visual warnings, haptic braking which involves partial braking along with auditory and visual warnings.
If applicable, identify the manufacture of the defective or noncompliant component: Hazard and Turn Signal Lighting parameters during Active Brake Assist (ABA)

Chronology of Noncompliance Determination
Provide the chronology of events leading up to the defect decision or test data for the noncompliance decision.
February 2020, DTNA began an investigation to review all its features related to ABA events as part of a study to develop systems for new trucks. During this study, it was identified that certain features may need further review to ensure the current product met the provisions of FMVSS 108. March 2020 through April 2020, Product Validation conducted tests on certain vehicles to identify any potential non-compliance, and an extensive engineering investigation was undertaken to understand all the features of ABA and how they interact together. During this study, it was identified that in certain situations the hazard warning signals flash at a rate of 140 flashes per min. An in-depth review of NHTSA regulations and interpretations related to this issue indicated a potential non-compliance with the flash rate provisions. May 6, 2020, DTNA determined that a non-compliance existed as to the flash rate for the hazard warning lamps and decided to file a Part 573 non-compliance information report and petition for exemption from the notice and remedy provisions of the Safety Act for this issue. DTNA believed that this non-compliance was inconsequential as it relates to motor vehicle safety, as the occurrence is extremely rare, for a very short duration and does not contribute to confusion or distraction for other motorists. DTNA also recognized that the hazards automatically flash in severe brake events but deemed this not a non-compliance, nor an issue that needed NHTSA approval, based upon the permission granted to GM in essentially similar situations.
June 4, 2020, DTNA filed a petition for exemption from notification and remedy provisions of motor vehicle safety act for non-compliance with FMVSS no. 108, lamps, reflective devices and associated equipment. Between early June 2020 to Late July 2020, DTNA communicated with NHTSA, at the agency’s request, regarding DTNA’s non-compliance information report and inconsequentiality petition. DTNA made several verbal updates, presentations and provided evidence and data to support the inconsequentiality petition pertaining to hazard warning signals flashing at 140 flashes per min during certain ABA events that involves full braking. July 13, 2020, upon NHTSA’s request, DTNA amended the inconsequentiality petition to include
FMVSS S14.9.3.9.3 – flasher performance requirements as an additional non-compliance basis. Between late August 2021 to late December 2021, DTNA again reviewed the inconsequentiality petition with NHTSA at the agency’s request, culminating in an amendment to the Part 573 non-compliance information report and petition for exemption.
On March 20, 2023, DTNA received notice of denial of the inconsequentiality petition for noncompliance. Therefore, out of abundance of caution, and per the requirements of Motor Vehicle Safety Act, DTNA submitted a new Part 573 report in light of the agency’s response.
On April 3, 2023, DTNA amended the Part 573 to include component manufacture’s information. In addition, there have been no known reports of claims, injuries, or accidents due to the subject non-compliance. On April 11, 2023, DTNA amended the Part 573 to include one truck that was believed still within DTNA’s possession but later determined to have been sold. Later in April 2023, DTNA re-analyzed the population and the models covered; although the total number of vehicles remains the same, the 49X model type of one affected vehicle was not listed in the recall report. The present addendum corrects that error. On May 5, 2023 DTNA updated nomenclature referring to ABA to be consistent with vehicle literature. Also added final Remedy statement. There are no claims, warranty, field or service reports. There are no death and/or injuries reported that DTNA is aware of.
Identify the Remedy
Describe the defect/noncompliance remedy program, including the manufacture’s plan for reimbursement.

On the affected vehicles, during certain ABA events, the hazard warning lights and headlights may flash
improperly, which can confuse other road users, increasing the risk of a crash. ABA events occur only after
multiple warnings to the drive including auditory and visual warnings, haptic braking which involves partial
braking along with auditory and visual warnings.
A Daimler Truck North America authorized service facility will update the software for the hazard warning lights.
The recall will take one half hour and will be performed free of charge.
IMPORTANT: When the recall has been completed, locate the base completion label in the appropriate location
on the vehicle, and attach the red completion sticker provided in the recall kit (Form WAR260). If the vehicle
does not have a base completion label, clean a spot on the appropriate location of the vehicle and first attach
the base completion label (Form WAR259). If a recall kit is not required or there is no completion sticker in the
kit, write the recall number on a blank sticker and attach it to the base completion label.

February 2020, DTNA began an investigation to review all its features related to ABA events as part of a study to develop systems for new trucks. During this study, it was identified that certain features may need further review to ensure the current product met the provisions of FMVSS 108. March 2020 through April 2020, Product Validation conducted tests on certain vehicles to identify any potential non-compliance, and an extensive engineering investigation was undertaken to understand all the features of ABA and how they interact together. During this study, it was identified that in certain situations the hazard warning signals flash at a rate of 140 flashes per min. An in-depth review of NHTSA regulations and interpretations related to this issue indicated a potential non-compliance with the flash rate provisions. May 6, 2020, DTNA determined that a non-compliance existed as to the flash rate for the hazard warning lamps and decided to file a Part 573 non- compliance information report and petition for exemption from the notice and remedy provisions of the Safety Act for this issue. DTNA believed that this non-compliance was inconsequential as it relates to motor vehicle safety, as the occurrence is extremely rare, for a very short duration and does not contribute to confusion or distraction for other motorists. DTNA also recognized that the hazards automatically flash in severe brake events but deemed this not a non-compliance, nor an issue that needed NHTSA approval, based upon the permission granted to GM in essentially similar situations.

FMVSS 108, requires the hazard warning signal lights to be driver controlled and flashing rate to be between 60-120 flashes per min and that the activation of the hazard warning operating unit be “driver controlled.” FMVSS 1 : 108 – Lamps, reflective devices, and assoc. Equipment FMVSS 2 : NR
Description of the Safety Risk : On certain vehicles with DTNA’s ABA system will automatically activate the hazard lamps if the vehicle’s safety system engages in extreme evasive braking, which can increase the risk of a crash for other road users. NHTSA considers the automatic hazard activation in these circumstances, as well as the flash rate at which the hazard lamps’ flash rate, noncompliance under FMVSS 108 Lamps, reflective devices, and associated equipment.
Description of the Cause : NR Identification of Any Warning
that can Occur : ABA events which progress to a full emergency braking stage occurs only after multiple warnings to the driver including auditory and visual warnings, haptic braking which involves partial braking along with auditory and visual warnings.

February 2020, DTNA began an investigation to review all its features related to ABA events as part of a study to develop systems for new trucks. During this study, it was identified that certain features may need further review to ensure the current product met the provisions of FMVSS 108. March 2020 through April 2020, Product Validation conducted tests on certain vehicles to identify any potential non-compliance, and an extensive engineering investigation was undertaken to understand all the features of ABA and how they interact together. During this study, it was identified that in certain situations the hazard warning signals flash at a rate of 140 flashes per min. An in-depth review of NHTSA regulations and interpretations related to this issue indicated a potential non-compliance with the flash rate provisions. May 6, 2020, DTNA determined that a non-compliance existed as to the flash rate for the hazard warning lamps and decided to file a Part 573 non- compliance information report and petition for exemption from the notice and remedy provisions of the Safety Act for this issue. DTNA believed that this non-compliance was inconsequential as it relates to motor vehicle safety, as the occurrence is extremely rare, for a very short duration and does not contribute to confusion or distraction for other motorists. DTNA also recognized that the hazards automatically flash in severe brake events but deemed this not a non-compliance, nor an issue that needed NHTSA approval, based upon the permission granted to GM in essentially similar situations. June 4, 2020, DTNA filed a petition for exemption from notification and remedy provisions of motor vehicle safety act for non-compliance with FMVSS no. 108, lamps, reflective devices and associated equipment.
Between early June 2020 to Late July 2020, DTNA communicated with NHTSA, at the agency’s request, regarding DTNA’s non-compliance information report and inconsequentiality petition(To be continued in attachment) Description of Remedy :
Description of Remedy Program : On the affected vehicles, the parameters controlling the enablement of
hazards and related functionality flashing automatically during an ABA emergency braking event will be disabled.
