CHILD SEAT:VEHICLE LATCH ANCHOR
General Motors, LLC (GM) is recalling certain 2020-2023 Chevrolet Equinox and GMC Terrain vehicles. The four rear-seat lower child seat LATCH anchorage bars may have excessive powder coating, which could prevent a child seat from being installed with the anchorage bars. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 225, "Child Restraint Anchorage Systems."
Risk: The inability to install a child seat with the LATCH anchorage bars could result in an unsecured child seat, increasing the risk of injury in a crash.

ID: 2110243LANE DEPARTURE: ASSIST
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.

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)
