Problem Mack Trucks, Inc. (Mack) is recalling certain 2010-2018 MRU and 2019-2025 Terrapro towing vehicles. The vehicles are missing the anti-lock brake (ABS) warning light and circuitry that controls the anti-lock brake function for an attached trailer. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 121, "Air Brake Systems." Risk Driving without a functioning anti-lock brake system may result in the trailer not braking as intended, increasing the risk of a crash. Fix 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. Mack's number for this recall is SC0474.

Two numbers, one recall

Every safety recall carries two identifiers. SC0474 is the number Mack assigned in its own system: it is what appears on the owner letter, on the dealer’s service screen and on the repair order. 25V030000 is the number NHTSA filed the same recall under when the manufacturer reported it, and it is the one every federal record, this site included, is keyed on.

The repair is free by federal law for vehicles up to fifteen years old. Whether one particular vehicle is included is settled by its VIN against the manufacturer’s build list, not by its model year.

Both lookups check a VIN against the manufacturer’s own list and say whether the repair is still outstanding on that vehicle.

Common questions

Which vehicles does SC0474 cover?

2010–2025 Mack MRU and 1 other Mack model, 142 vehicles by the manufacturer’s count. A recall covers a build range, so the VIN decides whether one particular vehicle is in it.

Does the SC0474 repair cost anything?

No. The manufacturer must remedy a safety defect at no charge for vehicles up to 15 years old from first sale.
