Mack Trucks, Inc: Missing ABS Function for Trailer/FMVSS 121

Agency Publication Date: January 23, 2025

Sign in to monitor this recall

Summary

Mack Trucks, Inc. is recalling 142 towing vehicles, specifically certain 2010-2018 MRU models and 2019-2025 Terrapro models. These vehicles were manufactured without the required anti-lock brake (ABS) warning light and the circuitry needed to control ABS functions for attached trailers. Dealers will install the missing warning light and circuitry free of charge to bring the vehicles into compliance with federal safety standards.

Risk

Driving a towing vehicle without a functioning trailer ABS may cause the trailer's brakes to perform unpredictably during heavy braking. This lack of anti-lock control increases the risk of trailer wheels locking up, potentially leading to a loss of control or a crash.

What You Should Do

  1. Check your vehicle's model and year to see if it is a 2010-2018 Mack MRU or a 2019-2025 Mack Terrapro towing vehicle.
  2. Contact any authorized Mack Trucks dealer to schedule a free appointment for the installation of the ABS warning light and necessary circuitry.
  3. Refer to Mack recall number SC0474 when speaking with the dealer or customer service.
  4. Verify the repair: Dealers will add an ABS warning light and circuitry, free of charge. Owner notification letters were mailed April 28, 2025. Owners may contact Mack's customer service at 1-800-866-1177.
  5. If you have additional questions, contact the NHTSA Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153) or visit www.nhtsa.gov.
