Numerous occurences especially recently of shift vehicle to park when vehicle has been parked, turned off and already shifted into park position. Several occurrences where almost every time within 24 hours I use my cruise control and air conditioner at the same time my check engine light will come on as well as the stability trac indicator which then causes my air conditioner not to work and inability to start the vehicle due to having a check engine light on.

I have numerous warnings, shift to park, steering, cross traffic, this endangers myself and anyone else around me, i have read several class action suits involving these problems and it could cause my vehicle to pose a danger, I have taken my vehicle in to a certified dealer and they state there is no known recalls associated with my vehicle which is strange because GMC knows that there are thousands of vehicles having the same problem, did I buy a lemon? These problems are clearly manufacture related and in no way normal wear and tare. I should not have to compensate these issues when I paid near 40,000 for

This vehicle has always since we bought it gave us tremendous problems while driving during a snowy day. Brakes typically do not work, at times even going through a red light and thankfully not been in an accident. Recently, the stability control system and the antilock braking system stopped working while under a snow storm. Unfortunately, we took it to the nearest delearship to get it fixed and we were told that the problem was due to the snow, but after the snow everything was good. Unfortunately, people do not have the money to pay for a vehicle and have it parked during the winter, that is what is happening to us. Because nor the dealership or GMC has done anything to help. This has been reported since December 2018, the vehicle has 34500 miles on it and is relatively new now, but we should not have these issues. It is of our knowledge that many people who bought this vehicle have the same issues. It would be good if they accept these vehicles have issues and correct them prior to promoting and selling to customers. Since they did not correct these issues prior to some individuals to purchase the vehicle, they should work on a solution via a re-call to avoid any injuries to families of their vehicle's owners.

It is epidemic in their Acadias. Stationary and putting it into park. It doesn't recognize it's in park! it's been occurring off and on over a week, not today, every time I try to turn off the vehicle.

On separate occasions, both parked turned off and running down highway, the dash lights lit up and alarms chimed. Car wouldn't start, no cold A/C. the "service power steering" message displayed. Car didn't turn as well. Couldn't shift. After doing so for a about 2-3 minutes it would go back to normal.
