Recalls, owner-reported complaints, investigations and safety data

Data refreshed

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.

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.

As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 208, “Occupant Protection.”
The risk: Without an owner's manual to consult, owners may not know how to safely use and operate the vehicle, increasing the risk of injury in a crash.
The remedy: Dealers will reset the vehicle radio, which will facilitate automatic download of the electronic owner’s manual, free of charge. Owner notification letters were mailed April 16, 2026.

Recent owner complaints

Reports submitted to NHTSA, shown in the owner's own words

Other / unspecified
Filed Aug 29, 2026

The vehicle was delivered from the factory with a severe size mismatch between its primary rolling stock and its emergency spare tire. The truck features factory-installed 20-inch wheels and tires but was manufactured and shipped with an undersized 18-inch spare tire assembly secured underneath the bed. On a heavy-duty 3500-series truck built for heavy towing and hauling, utilizing a drastically different tire diameter during an emergency road event forces the rear differential and transfer case to spin at mismatched speeds. This creates an immediate risk of sudden mechanical drivetrain failure, loss of vehicle control, or compromised braking stability while operating under load on public highways. Consumers relying on factory equipment during emergency roadside scenarios should not be exposed to hidden mechanical hazards due to factory assembly omissions. Upon discovering the factory defect, the local dealership attempted remediation by supplying a shop take-off wheel and an aged, three-year-old tire (DOT 2223). This highlights that while individual dealerships scramble to fix these factory omissions with makeshift inventory, consumers purchasing new heavy-duty vehicles are still absorbing compromised, aged safety equipment due to lack of manufacturing quality control. I have also filed a complaint with GM and have requested immediate remediation with a correct new tire and wheel and am waiting for a response.

Have been driving it on four separate occasions and the engine will start running rough and shut off leaving me with no power brakes or power steering. Once when I was going about 30 miles an hour the other three times when I was coming to a stop with a trailer on just took it in Kendall Chevrolet for the first time they are still working on it but unable to duplicate the problem this is a very serious safety concern for myself and possibly for others that have the same issue
