On Friday, December 6, 2024, my -??check engine light-?? illuminated on my 2017 GMC Sierra pickup. The engine is the gasoline version of the 5.3 liter. I took my truck to Brogden Buick/GMC in Olathe, KS. They informed me the trouble code was 219a, indicating there was a problem with the fuel/air ratio. On Monday, December 9, 2024, I was contacted and informed the fuel injectors needed to be replaced at a cost of approx. $2700. Based upon research I-??ve conducted GM-??s fuel injectors have been a service concern since approximately 2014. Service bulletin DCS5097 (N182198000-Special Coverage Engine Fuel Injector) was issued on July 26, 2019 that included my engine configuration. However, this particular bulletin does not appear to cover my Kansas based vehicle. I just had my vehicle at Brogden for a previous check engine light two weeks ago. This required replacing the fuel cell pressure sensor at just over $700. These repairs seem to be related. I-??m reading that 2023 and 2024 Chevrolet and GMC trucks are also having fuel injector issues. This seems to be an ongoing problem that GM does not appear to be appropriately addressing. My truck is relatively low mileage with only 58,786 miles. It has never towed, is garage kept and is maintained in a pristine condition. I-??ve never experienced fuel injector issues any any previously owned vehicle.

Vehicle has a hard shift in the lower gears. I have been told by GM authorized dealers and garages that the official suggestion from GM is a transmission flush, and that this may not resolve the issue. This service usually runs around $350+, and is not reimbursed at all or in part by the manufacturer. This has caused tire spin in parking lots and low speed situations (like crosswalks), and only seems to be getting worse as time goes on. This seems to be a widespread issue, with a large number of consumers reporting the same issue, and really seems to be a manufacturer defect

Cold start after vehicle sits for a while vehicle shark bites and stutters. When you try and drive vehicle before it-??s been warmed up significantly. It-??s a safety concern because it feels very danger and could cause an accident. Alamo At caused my truck to stall out the other day with my children in it and a large accident. Dealership is dismissed my concern and says it-??s normal gmc defects that I have to deal with. I will sue GMC if I have to.

The vehicle was in motion on a city street, when the vehicle completely powered off. The steering wheel locked. This occurred on 11/22/2020 and 11/23/2020. The following message is on my dashboard 'steering assist is reduced drive with care.'
