What is wrong
Autocar, LLC (Autocar) is recalling certain 2023-2027 E-ACTT terminal tractors. The Antilock Braking System (ABS) Electronic Control Unit (ECU) may be improperly secured, allowing the ABS ECU to separate.
The risk
A separated ABS ECU may become damaged, causing the ABS system to fail and increasing the risk of a crash.
Why brake defects matter: Reduced braking or a loss of brake assist lengthens stopping distance and increases the risk of a crash.
The remedy
Autocar will replace the fasteners, free of charge. Owner notification letters were mailed September 25, 2026. Owners may contact Autocar customer service at 1-888-218-3611. Autocar's number for this recall is ACTT-2601.
About the brakes
The service brakes are the system you use every time you press the pedal — hydraulic or air components plus the electronic controls that manage them.

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.
