May 25, 2022 NHTSA CAMPAIGN NUMBER: 22V374000
Double Check Valve May Trap Air and Impair Braking
Brake component failure and increased stopping distance may increase the risk of a crash.
NHTSA Campaign Number: 22V374000
Manufacturer Daimler Trucks North America, LLC
Components SERVICE BRAKES, AIR
Potential Number of Units Affected 4
Summary
Daimler Trucks North America LLC (DTNA) is recalling certain 2022 Freightliner Cascadia vehicles. The double cccccc may trap air which can impair service brake function and lock the rear axle while the vehicle is in motion. A locked rear axle may cause brake components to fail or increased stopping distance.
Remedy
All vehicles have been remedied, therefore no owner notification letters are necessary. Owners may contact DTNA customer service at 1-800-547-2712. DTNA’s number for this recall is FL-936.
Notes
Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.nhtsa.gov.

All vehicles within this recall campaign have been repaired prior to the publication of a Dealer’s Bulletin or Owner Notification. All impacted serial numbers were inspected/repaired on 6/13/2022.
Chronology :
On or about May 5, 2022, DTNA received a notification from its Engineering group that, while testing a specific DTNA owned vehicle that had not been sold to commerce, there was a situation that resulted in an unintended brake application. At that time, DTNA believed the issue to be an isolated occurrence on only one vehicle with unknown cause and unknown population. DTNA promptly began an investigation into that vehicle and other vehicles like it, which were produced in only a very limited production run. On or about May 16, DTNA determined that the occurrence could occur on a population of 4 vehicles, as listed on the prior 573 report. On or about May 18, 2022, after DTNA verified the limited population of vehicles potentially subject to the defect to the extent necessary to declare a recall and file that 573 report, out of abundance of caution, DTNA decided to conduct a voluntary safety recall campaign for this very specific group of vehicles to remove the double check valve from the backup pneumatic circuit. As of today, DTNA is not aware of any incidents due to this defect. June 3, 2022, DTNA captured and repaired the 4 vehicles at DTNA’s own expense.

Production Dates : NOV 16, 2021 – DEC 17, 2021 VIN Range 1 : Begin : NR End : NR Not sequential Description of Defect : Description of the Defect : On a specific DTNA-owned truck used for testing purposes, the double check valve was found to be trapping air in the backup pneumatic air circuit under rare situations. Trapped air may cause unintended or prolonged service brake application, which may result in rear axle to lock while the vehicle is in motion. Out of an abundance of caution, DTNA is recalling the limited population of vehicles built to date with the same, unique valve configuration. Note as of June 3, 2022: DTNA has removed the particular double check valve from all affected vehicles, thereby eliminating the known defect. FMVSS 1 : NR FMVSS 2 : NR Description of the Safety Risk : Rear axle locking up while the vehicle is in motion may result in generation of additional frictional force, which may cause the brake components to fail prematurely due to over time heat buildup. In rare cases, especially if the axle lock up is ignored by the driver, may increase the vehicle stopping distance, increasing the risk of a crash. As of today, DTNA is not aware of any incidents due to this defect. Note as of June 3, 2022: DTNA has removed the particular double check valve from all affected vehicles, thereby eliminating the known Part 573 Safety Recall Report 22V-374 Page 2 The information contained in this report was submitted pursuant to 49 CFR §573 safety risk. Description of the Cause : NR Identification of Any Warning that can Occur : NR Involved Components : Component Name 1 : Double Check Valve Component Description : Pneumatic Valve Component Part Number : BW 278614 Supplier Identification : Component Manufacturer Name : Bendix Corp Heavy Vehicle Systems Group Address : 100 Jessica ln Del Rio Texas 78840-8527 Country : United States Chronology : On or about May 5, 2022, DTNA received a notification from its Engineering group that, while testing a specific DTNA owned vehicle that had not been sold to commerce, there was a situation that resulted in an unintended brake application. At that time, DTNA believed the issue to be an isolated occurrence on only one vehicle with unknown cause and unknown population. DTNA promptly began an investigation into that vehicle and other vehicles like it, which were produced in only a very limited production run. On or about May 16, DTNA determined that the occurrence could occur on a population of 4 vehicles, as listed on the prior 573 report. On or about May 18, 2022, after DTNA verified the limited population of vehicles potentially subject to the defect to the extent necessary to declare a recall and file that 573 report, out of abundance of caution, DTNA decided to conduct a voluntary safety recall campaign for this very specific group of vehicles to remove the double check valve from the backup pneumatic circuit. As of today, DTNA is not aware of any incidents due to this defect. June 3, 2022, DTNA captured and repaired the 4 vehicles at DTNA’s own expense.
