“Unintended surge of acceleration. Will happen randomly about once a week when under slight acceleration. It feels like the accelerator goes full throttle for one second, causing a huge surge of acceleration, almost plowing into the car in front of us multiple times. The last time it happened while in reverse. Dealer examined the car and said there are no codes stored in the computer and couldn't replicate the problem. We get the car back tomorrow and my file drives it with our 4 kids, so this is vary scary (for the safety of our family and others on the road). …”

“Vehicle started showing a po308 code. Called sewell gmc In midland where I purchased the vehical they were 2 months out on diagnostic services. So I took it to another shop. They ran a camera into the problem cylinder and for scaring on the walls. They said it was due to the afm system and the engine was unrepairable. So now I am out 17,000 dollars and stranded over 700 miles from my home due to a manufactured defect.”

“Catastrophic engine failure to the GM 6.2L engine. Mechanical issue - cam or crankshaft came apart. Safety to myself and/or others as I was driving on the road in traffic when the issue occurred and had complete loss of power. I was able to avoid traffic and get the SUV to the shoulder of the road. The issue was confirmed by my auto service provider. No warning lamps or messages prior to failure. Once failure occurred, the check engine light started to blink.”

“P0304 and P0306 misfiring and compression on both cylinders is 0. Both lifters have broke and collapsed. It started with a noise, once checked by the mechanic, we were told the lifter was going bad, before we could get it repaired it completely broke and that is when the check engine light came on and went off repeated times. At this time it is pouring out black smoke when driving and must have a complete engine replacement. The replacement work has been quoted for $10479.57.”

“There was a problem with the catalytic converter that I was not aware of when I purchased the vehicle. There were no issues with performance for a few days until the engine began misfiring on the interstate and it forced me to pull over during heavy traffic. This was all in a week and the dealer has refused to take any responsibility despite being a Chevy Certified Dealer. I am now getting the vehicle repaired by my local mechanic due to the need for this vehicle. I have made General Motors aware of the situation.”
