Recalls, owner-reported complaints, investigations and safety data

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.
0
Safety recallsA safety recall is issued when a manufacturer or NHTSA determines that a vehicle has a safety-related defect or does not comply with a federal motor vehicle safety standard. Recall repairs are free. Whether a specific vehicle is covered depends on its VIN — a recall listed for a model year does not necessarily apply to every vehicle of that year.

InvestigationsNHTSA opens an investigation to examine whether a safety defect may exist. An open investigation is not a determination that a defect exists, and many investigations close without a recall. Investigations can, however, lead to one.
0
Crash or fire reportedComplaints whose submitter recorded that a crash or a fire occurred. These are the reporter's own answers on the NHTSA form, not verified findings.

EXTERIOR LIGHTING:TURN SIGNAL

Aug 25, 2023
27,418 units potentially affected
The defect: Mack Trucks, Inc. (Mack) is recalling certain 2015-2023 GU and GR vehicles. The turn signals may be positioned incorrectly, reducing their visibility. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 108, "Lamps, Reflective Devices, and Associated Equipment."
The risk: Low turn signal visibility may not alert other drivers to a turning vehicle, increasing the risk of a crash.
The remedy: Dealers will add additional turn signal lighting, free of charge. Owner letters were mailed September 25, 2024. Owners may contact Mack's customer service at 1-800-866-1177. Mack's number for this recall is SC0448.

Service Campaign: On certain Mack GR model trucks built between May 10, 2021, to March 28, 2023, it has been determined that the air horn and battery cable could interfere with each other causing the horn to rub through the insulation on the battery cable. To correct these findings, install a new battery cable securing bracket that improves the routing of the battery cable away from the horn.

They are not recalls: repairs described in a bulletin are usually only free if the vehicle is still under warranty or the manufacturer has extended coverage.
