| Seat Belt problems |
When turning on the car, a message pops up on the dash and will not go away. Dashboard says “ service safety restraint system”.
“service safety restraint” light comes on and the dealership cannot pin point exactly what the issue is without taking the entire seat and air bag out. It’s come on 3 times. First time was linked to the overhead console needing replaced. Months later the light came on again and a seat harness connection was bad. It was replaced and light was off. 8 months later the light is back on again and they replaced the connection again and the light is off for now. This is a safety issue and should be a recall!.
The contact owns a 2021 GMC Yukon. The contact stated that while driving at various speeds, the forward collision avoidance system erroneously activated, causing the vehicle to suddenly slow down. The vehicle was taken to the local dealer who serviced the forward collision avoidance system camera and sensors. No further information was available. Additionally, while driving at highway speeds, there was a knocking sound coming from the engine compartment, and the seat restraint failure message was displayed. The cause of the failure was not yet determined. The manufacturer was notified of the failure. The failure mileage was 20,000.
While I was driving home from the grocery store with my 4 kids our 2021 GMC Yukon xl (5. 3l v8 engine), the vehicle suffered a sudden, catastrophic mechanical engine failure without warning. The engine began violently shaking, lost major propulsion, and dropped into a severe misfire state when we were coming down the highway. This created an immediate safety hazard on the road, as I suddenly lost the ability to safely accelerate or maintain highway speeds while hauling my children. A certified technician diagnosed the issue as a complete failure of the active fuel management hydraulic valve lifters and bent pushrods, a known manufacturing defect explicitly documented in gm technical service bulletin pip5776f. The internal failure required a total engine teardown and valvetrain replacement, costing over $10,000 out of pocket. General motors has failed to issue a safety recall for this specific 5. 3l valvetrain defect, despite it causing unexpected engine stalls, severe power loss, and immediate traffic hazards for drivers. This defective component poses an ongoing safety risk to families and should be upgraded to a mandatory safety recall. I am afraid to drive it every time I get on the highway in fear it could shut down again.
Our rear seat belts no longer retract after unbuckling. We do not know if they will work in the case of an accident as they will not even retract their own weight after unbuckling.
Service safety restraint system came on my vehicle and I just purchased this vehicle 3 weeks ago.
