“I have had 2 different instances where my vehicle stops in the middle of a busy intersection or traffic and have no warning what so ever. Vehicle just shuts off and I am not able to turn back on to move out of the way. First time I got it repaired it was related to the fuel pump and now I am waiting to hear back from my mechanic to see what the issue is but so far it is an indication of the fuel pump as well. …”

NHTSA complaint #11737870, filed 2026-05“Out of nowhere and driving this morning, my engine reduced power came on. Then I started losing power in the car then it died on me once out of nowhere.

NHTSA complaint #11726152, filed 2026-03“I was driving the vehicle on the highway the cruise control was on. All of a sudden I got a warning on vehicle info panel that stated vehicle power is reduced. The vehicle decelerated on its own and I could not accelerate past 55. The check engine light came on. I pulled off the road and turned the vehicle off. After about 10 minutes, I started the car back up and proceeded down the highway at normal speed. The check engine light remained on. I stopped at a Chevrolet dealer service center in Ft Stockton, TX, to have the vehicle looked at. …”
NHTSA complaint #11740102, filed 2026-05“My GMC Terrain was stopped in traffic at a Red Light. When I stepped on the gas pedal to proceed, the SUV shut-down. Could not move SUV in Traffic. Called Police and SUV was towed. SUV towed to GMC Dealer. The K111 Fuel Module was causing the problem. GMC Dealer Repair Shop removed and replaced the K111 Fuel Module. They claimed SUV is OK. I don't trust this SUV any longer. I read of similar problems with 2022 GMC Terrain and the Fuel Module defect causing the SUV to shut down. This is a safety hazard to the Driver and other vehicles on the highway.”
