The Onstar system and Wifi connectivity stopped working over a week ago. The vehicle is less than two-years old, but it had three recalls which we took it in for this past week. We were told by the GMC dealership that one of the recalls would correct the problem with the Onstar and Wifi connectivity. However, it did not and now we are being told that the Onstar module needs to be replaced, and the dealer says it isn't under warranty. GMC has tied the warranty of the Onstar module to the miles instead of the time in-service. Many other customers are experiencing the same issue. GM markets Onstar as one of their safety features and as such repairs should be covered by the manufacturer.

The contact owns a 2022 GMC Sierra 1500. The contact stated that upon starting the vehicle, the brakes warning light illuminated. The vehicle was taken to the dealer, who diagnosed failures with the rear brake rotors and brake pads. The vehicle was repaired. The manufacturer was notified of the failure, a case was opened, and the vehicle was repaired at no cost. The failure mileage was 16,000.

I attempted to start my vehicle and it turned over and at the end of trying it sounded like it wanted to start. This repeated itself with no change. I contacted the dealer which I purchased it from and the service mgr said it was the fuel pump control module. Numerous 2021 Yukon had this problem and there is both a service bulletin and a recall for this part. N212332040. My vehicle is NOT on recall. I attempted to have it towed to the local Chevy dealer and was unable to as NO local tow company had the tool to put the transmission in neutral. They all wanted to drag it onto the trailer. Bad design that it can not be put in park if it’s not running. I purchased a replacement fuel pump control module part 13554821 from the dealership. I installed it and the problem was fixed. I have the defective part if needed. This would have been much more of an issue if it happened anywhere other than my house, especially with the inability to put he transmission in neutral !!

Engine misfiring and rough idle with occasional flashing engine light. Dealer said no codes to know what to look for despite replicating issue. Eventually it threw a Cylinder 5 misfire and thus GM dealer was able to look further. They found metal in oil pan and concluded a bearing issue and would need to replace engine.

Airbags did not deploy. A car run a red light. I hit it on its passenger side. I was going about 45mph before the crash. I did slam my breaks before impact but I would guess I was still going 30-35mph at impact. Car has not been inspected yet. It is still in our possession. We have made in insurance claim. No warning light of any kind were on before the crash.

Vehicle is showing message of “shift to park” while trying to turn ignition off and currently in park. There is a current recall but it is saying this vehicle is not included in recall.

I tried to honk the horn when a car started to come into my lane and discovered that it was not working. I took it to the dealership, and they said it needed a new steering wheel as the contacts that operate the horn were faulty. they told me that the steering wheel airbag would not be operational due to this problem until it was fixed. This is a 2022 pickup with only 10,000 miles on it. I’ve never had to use the Horn before I, so to discover that the issue is pretty serious was disconcerting, and of course my 36 month bumper-to-bumper is used up. This vehicle is basically brand-new, and there should be a recall on this vehicle.
