What is wrong
Daimler Trucks North America, LLC (DTNA) is recalling certain 2020-2023 Freightliner Cascadia and 2022 Western Star 49X vehicles previously repaired incorrectly under recall numbers 23V073 or 22V817. The brake modulator valves on the front axle may corrode and cause the vehicle to pull to one side during braking initiated by Electronic Stability Control (ESC) or Roll Stability Control (RSC).
The risk
Brakes that pull to one side may cause a sudden change in vehicle direction, increasing the risk of a crash.
Why stability control defects matter: If stability control does not work as designed, the vehicle may not correct a skid it otherwise would.
The remedy
Dealers will replace the brake modulator valves, free of charge. Owner notification letters are expected to be mailed November 8, 2026. Owners may contact DTNA customer service at 1-800-547-0712. DTNA's number for this recall is F1039. Vehicles repaired under the prior recalls will need the new repair completed.
About the stability and traction control
Stability control uses steering-angle, yaw and wheel-speed sensors to detect a skid and correct it automatically.

What to do
- Enter your VIN in NHTSA’s lookup (below) to confirm that your vehicle is included and that the repair has not already been done.
- Call a dealer for the brand and book the repair. Quote NHTSA campaign 26V-583 and the manufacturer’s number F1039.
- Note any stability or traction warning lamps and drive with extra margin on wet or slippery roads until the fix is done.
- Safety recall repairs are carried out free of charge by the manufacturer’s dealers. If you already paid for this repair yourself, ask the manufacturer about reimbursement and keep your receipt.
Check by VIN
A campaign rarely covers every vehicle of a model year. Enter your 17-character VIN to find the recall campaigns filed for your make, model and model year. The VIN is on the driver’s side of the dashboard (visible through the windshield), on the door-jamb label, and on your registration and insurance documents.
Is a recall still open on your vehicle? Only NHTSA’s official VIN check can say whether a campaign applies to your exact vehicle and whether the repair has already been done.
Your VIN is decoded with NHTSA’s public vPIC service to identify the make, model and year. It is not stored and is not added to any page address.
