The contact owns a 2016 GMC Sierra 1500. The contact stated while driving 60 MPH, the power steering assist became inoperable. While driving at slow speeds, the power steering assist was intermittently inoperable. The power steering warning light was illuminated was intermittently inoperable. The local dealer was contacted, but the vehicle was not diagnosed or repaired. The manufacturer was not contacted. The failure mileage was approximately 90,200.

Approx 17 months after purchase, tailgate release button (the lower button on the tailgate that is used to open (fully) the tailgate) stopped releasing the tailgate, however tailgate releases randomly when opening one of the truck doors. Based on the "fix" that has been subscribed for existing Chevy & GMC trucks with recalls for this same problem (although my truck isn't covered by current recalls) , my mechanic has ordered a new tailgate release switch (or whatever it is called) which they are installing tomorrow.

The contact owns a 2022 GMC Sierra 1500. The contact stated while driving at approximately 55 MPH, the contact observed a loud sound coming from the front passenger’s side of the vehicle. The contact stated that the steering wheel then pulled to the right. The vehicle was steered to the side of the road and inspected. The vehicle was towed to a dealer where it was awaiting a diagnostic test. The manufacturer was notified of the failure. The failure mileage was approximately 32,000.

Vehicle will not shift to park- The cars engine is off and will not turn on, while the car physically will not turn off. I have to move the shifter until vehicle recognized it was in park. resulting in me getting stuck in my vehicle. Multiple reports from other owners with no fix provided by GMC.

Code P0711 appeared during a scan after noticing some roughness during acceleration. Code shows transmission temperature sensor failure which is a known issue and recall for this vehicle model.

The paint delaminated from the clear coat in certain locations (mainly hood and roof) although the vehicle body has been well maintained. This has caused a foggy scratched appearance to the affected areas where the rest of the car looks great. This problem is well known across many GM vehicles in the 2015-2019 range and has led to significantly decreased value of the vehicle itself

The AFM/DFM system in these trucks are making the engines and transmissions go out around 70k miles. The lifters fail right around the same time factory warranty runs out then your left with a 6 thousand dollar bill to have it fixed. I hope this becomes a recall because numerous people I talk to are getting rid of they're gmcs and chevys and going elsewhere.

In late February/early March, my GMC Sierra with around 9000 miles had the following to occur on a cold start: check engine light came on as well as the service esc light & traction control light, truck shuddered and shimmied. Took for service on March 4, 2024 with 9774 miles on odometer, where service tech said they couldn't duplicate concern (see attachments: March Service Invoice Pg 1 & 2). Took truck home & same issues kept occurring especially on cold mornings & days. Took the truck back for service on April 1, 2024 with 10895 miles on odometer. Told them to keep it till its fixed & to start it on cold mornings because thats when problem occurs. They had truck till April 12, 2024 and were able to duplicate the concern. Dealer changed the fuel injector (that was not the problem). Service tech finally found the cylinder 8 has a misfire until vehicle gets to operating temperature. They replaced all 8 lifters in bank 2 (right side) & gave me an oil change. This seems to have fixed the problem, but I won't really know until winter 2025. My problem with this lifter issue is that this engine will probably only last for 3 maybe 4 years tops because of all the metal shavings that are roaming around in the engine. This has been a problem with GM engines for some time & GM has yet to fix it or at least take responsibility for their poor engineering. I paid over $70,000 (of which GM made around $17,000) for this truck only to have the engine probably make it for a few years. My last truck I kept for 10 years. I don't see this happening with this truck.
