2023 Gmc Terrain Complaints

My son was making a left onto a freeway on ramp after traffic cleared and the steering wheel completely locked up resulting in him going over the curb and rolling completely over in a steep ditch. This occurred at a low speed (no more than 25mph), confirmed by the Life369 app. My son's description was that it felt like the wheels were against a wall and the wheel wouldn't turn even though he was using both hands in an attempt to turn. My son said there was no warning lights or any other indication that he noticed, other than the complete locking up of the steering. The resulting rollover into the ditch has totaled the vehicle so it was not inspected by any collision shop. I attempted to check the steering in the tow yard but the vehicle had no power.

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.

The contact owns a 2023 GMC Terrain. The contact stated while driving 15 MPH, the message "Engine Power Reduced” was displayed on the instrument panel. The contact stated that the vehicle the lost motive power in the middle of the roadway. The check engine warning light was illuminated. The vehicle was towed to the dealer, who diagnosed a failure with the high-pressure fuel pump, causing fuel to leak into the oil, resulting in damages to the catalytic converter and Oxygen sensor. The vehicle was not repaired. The manufacturer was notified of the failure, a case was opened, and the contact was referred to the NHTSA Hotline for assistance. The failure mileage was 41,000.

While driving 40-45 mph the engine light came on and 50% loss of power was displayed on screen. Thankfully I wasn’t far from home and was in limp mode for the last 2 miles. The mileage of vehicle is 42,000 miles. The codes are reading low fuel pressure and faulty fuel pump. Any help would be appreciated as this shouldn’t be happening to this new of a vehicle.

At stop light turning right, the car stalled, cut on and cut back off, cut on and back off with about 30 cars behind me. Sputtering. On the dash board it said “Engine power reduced”. I had to be pushed out a main highway by police, and thankfully my [XXX] daughter wasn’t in the back seat. I have had this car 12 days with 48256 miles on it. I’m extremely concerned with the safety of this car. And when towed was leaking gas like fluid. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
