2021 CHEVROLET TAHOE Complaints

On three (3) different occasions, I put the SUV in Park and the car engaged, and the "P" lit up as engaged. As I took my foot off the brake, the SUV went into Drive and rolled. This last time, the SUV did this at my kid's school Ater putting it in Park, I took my foot off the brake and turned to get the kids unbuckled, and my foot accidentally pushed the gas pedal. The SUV went into drive on its own and the SUV drove over the sidewalk hitting a rock staircase causing an accident with all 4 kids in my SUV. This is the 3rd time, and I don't know what to do about it. Thankfully there were no kids in front of the SUV.

I have an on going problem with the emissions system on my 2021 Tahoe. The vehicle discharges raw diesel fuel and DEF from the exhaust tail pipe during cold startup. This discharge is overwhelming and is so strong it can be detected by smell from over fifty feet away. In addition to this issue the fumes enter the inside of the vehicle and at times it is so bad you need to open the windows. I believe this problem is unsafe as it poses a fire risk and a CO exposure risk to the vehicle occupants. The vehicle has been in the shop repeatedly for the past eighteen months with various parts replaced. To date none of the repairs have fixed the problem. In February GM issued a statement saying that this is normal operations.
