Steering wheel locks up and jerk’s loose suddenly when making a right turn, in these moments when the steering wheel jerks loose ;hands are off taken off the steering wheel otherwise injury can occur. Battery life 2 -yrs old is not performing optimally. Can not hold a sufficient charge and ESC light flashes. Vdnt valve leaks discovered.

Driver seat belt exhibits signs of fraying in area of belt hidden from view when not in use. When extended, hair-like fibers extend out, primarily from the car-forward side of the belt in the area coming out of the B-pillar and from behind the trim. It is available for inspection. Concerned that this may continue to degrade the integrity of the seat belt over time. There could be something sharp in the retractor, or flash on a piece of plastic trim hidden from view causing this. My understanding is that if there is a small nick on the edge of a safety belt it can tear across, and concerned that this condition could lead to a similar outcome over time and if the vehicle were involved in an accident. Upon taking to local dealership, was advised that this is a normal condition and not a concern. Advisor said technician told him that it is not fraying, it is a normal condition that can be exhibited by the belt fibers, especially towards the edges. They said the central portion of the belt is not exhibiting a similar condition and therefore not a concern. The fibers seem to have grown in quantity since vehicle purchase. I first recall seeing them during the pandemic, although became more concerned over time and finally took in prior to warranty expiration for review.

I just purchased this vehicle about 2 weeks ago, and was driving through the fog/cold weather and my check engine light came on. Went to O'Reillys and had them check the code. Came up as P0299 (My car was telling me that the engine power was decreased) I had a loss of power I could feel while driving as well. The code said turbo under boost. After I got back into town and the weather was warmer and no fog was present, the turbo started working again. I brought my vehicle into the dealer where I bought it from and they took it to their mechanic and supposedly performed an "update". I will see if I continue to have the same issue in cold weather as I live in Idaho and go to the mountains often.

My service brake assist light came on and then within seconds my vehicle then said engine power has been lowered and my vehicle pretty much shut down no steering no brakes couldn't do anything. Took it into the repair shop and my vacuum pump has shattered and now damaged my camshaft. I am aware there's been many other vehicles recalled with GM's vacuum pumps and I'm not sure why my year and model has not been included when it's doing the same thing and not to mention I have seen countless other cases of people saying same things happen to them with their GMC terrains.
