What this means for you

Real risk of harm even if no illness or injury has been reported yet. Stop using the product and follow the agency's guidance.

Our severity reasoning: The recall involves a structural vehicle defect (missing ABS circuitry) that increases the risk of a crash, but no injuries or fatalities are reported in the source text.

Plain-English summary

Mack Trucks, Inc. is recalling certain 2010-2018 MRU and 2019-2025 Terrapro towing vehicles. These vehicles are missing the anti-lock brake (ABS) warning light and the circuitry that controls the anti-lock brake function for an attached trailer. As a result, these vehicles fail to comply with Federal Motor Vehicle Safety Standard (FMVSS) number 121, "Air Brake Systems."

Driving without a functioning anti-lock brake system may result in the trailer not braking as intended, which increases the risk of a crash. The recall affects 142 vehicles in total.

Dealers will add the missing ABS warning light and circuitry free of charge. Owner notification letters were mailed on April 28, 2025. Owners may contact Mack's customer service at 1-800-866-1177.
