5 safety recall campaigns, 321 owner complaints filed with NHTSA.
Complaints are reports from owners of this model year, not findings about any particular vehicle, and a model that sold in large numbers will collect more of them. They are counted here as filed; nothing is inferred from them.
Missing bolts on the start-stop accumulator endcap could result in a transmission oil leak and may progress to a loss of propulsion, increasing the risk of a crash. A transmission fluid leak in the presence of an ignition source may increase the risk of fire.
A reduction of braking performance can increase the risk of a crash.
A damaged fuel line can create a fuel leak, increasing the risk of a fire.
If the SDM becomes inoperative, it will not detect a crash or command the necessary air bag deployment, increasing the risk of injury in the event of a crash.
If the front right intermediate drive shaft assembly separates while driving, the vehicle will lose propulsion, increasing the risk of a crash. If the assembly separates while parked on a grade, without the park brake engaged, the vehicle may move unintentionally, increasing the risk of a vehicle roll-away.
Two 2018 GMC TERRAINs can have entirely different histories, and a recall campaign usually covers a build-date window rather than a whole model year — which a VIN does not encode, so only the door-jamb label settles it. Scanning the VIN adds the decode, the crash tests, the fuel economy and the complaints matched to that exact engine, trim and assembly plant.
