Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“My ESC randomly comes on. Service parking brake message comes on intermittently. Messages pop a up saying steering wheel assist limited, drive with care. Again, all of these are intermittent but when they happen my steering wheel locks up. Even mid turn. Being intermittent it doesn’t always happen and weather seems to affect when it happens, or that’s a coincidence.”
NHTSA complaint #11629553, filed 2024-12“Friday July 25, 2025 I was driving my 2019 GMC Terrain SLE and when exiting the interstate the brake pedal got hard and I could not stop. After almost rear ending another vehicle, I got the vehicle into the ditch and safely off the road. After several attempts to correct the problem, I was unsuccessful. The vehicle was towed home and seen by a mechanic. The vacuum pump went out while I was driving.”
NHTSA complaint #11676573, filed 2025-07“We have been having varying issues with this GMC, and have found numerous others with the same issue. Vacuum pump went out while driving. Thankfully I was not going very fast and it stopped prior to hitting someone. This is a known issue, yet no recall from GMC. Vacuum pump is said to have been failing causing other engine and transmission issues that can never be re-created for the vehicle to be fixed.”
NHTSA complaint #11691600, filed 2025-10“I had just gotten off the highway and had gone less than a mile on a 35 mph road when the brakes acted like the antilock brakes came on for a brief second then the brake pedal became very hard to push. This resulted in me having a difficult time stopping the vehicle. The service brake light also came on.”
NHTSA complaint #11582751, filed 2024-04“Brakes got hard all of a sudden locked up, almost hit another car, front collision warning keeps going off and automatically hitting brakes with no one in front of me. I’ve read it could vacuum brake pump failure. Please recall this as many people have kids and could hurt them.”
