general problems of the 2017 GMC Acadia

Went to burt watson the end of may. Paid $250 to diagnose 3 problems. Trans was intermittently kicking into passing gear when starting from a stop position, a service engine light and passenger side blind spot warning would come on when nothing was there and other times wouldn't recognize a vehicle was there. Around the middle of July the battery began draining intermittently leaving me stranded at night away from home. The rear defogger began turning itself on and couldn't be shut off and was very hot to the touch. The drivers seat moved all the way forward on its own pressing me into the steering wheel and dash while I was driving at highway speed. Forcing me to change 2 lanes of traffic trying to get to the side of the road. I was told by the service manager that the rear fuse block had shorted out do to water intrusion from bad drain ports. This was replaced, and then I was told something else was draining the battery. And this was "one " of the things not covered by warranty. There is a service bulletin stating that there may be pinholes at the top of the a-pillars and d-pillars yet the dealership stated a new windshield was needed. There are several service bulletins indicating that such leaks can reek havoc on the electronics. The dealership has changed their estimate several times with still no solution in site. The vehicle has been sitting at the dealership since July. At one point it was communicated to me that gm would assist in the cost of the repairs when and if job was ever completed. They are now stating the cost to repair the issues is $5500. 00 and is my responsibility.

Manual drivers seat will not stay up. I set the seat high so I can see. Going down the road hitting normal bumps ,the seat slowly sinks all the way down. Dealership tried fixing but it did not work. Have record of repairs just in case this causes me to have a accident.

The drivers side front seat has something loose under the leather. There is something that moves when you go around turns or stops. It also makes noises and pops.

Hearing rattle sound from 2nd and 3rd row from day1 for 2017 GMC Acadia denali. Primary source seems(something inside) seats in 2nd row and may be 3rd row. Rattle can be heard when going over bumps or bad road patches on usual city roads. Seems whenever vehicle goes over a bad road patch, 2nd/3rd row seats vibrate a lot and rattle sound can be heard. Sometimes I can hear slight rattle from around passenger side 1st row door as well.

Cannot shift out of park. Ac stops blowing also. Electric seats stopped working. Replaced bcm modular, solenoid , entire shifter and more. It worked for two months. -happening again. Cannot shift out of park and the ac stops working. Seat are working at moment. It’s all intermittent. Currently dealer will not help me. No warranty anymore. Im on a site where thousands of GMC’s have this same problem. Im gonna have to bring back to another dealer but no one can figure it out how to fix this. I sent my last bill. I also had one before that with the shifter assembly and solenoid replaced. I cannot find at moment.
