2017 GMC Acadia

The transmission in my 2017 GMC Acadia needs to be replaced. According to an article from Qulll&Arrow, LLP, transmission problems affected the 2017, 2018, 2019 and some 2020 models, however, my VIN number is not included in this. I am reporting this so it can be documented in case other owners come forward and a pattern can be established.

Shift to park. Car will not register as in park. Have previously had issue fixed and has started again. Was told this is a common reoccurance and would likely happen again over time even if I pay to have it fixed again. Yesterday I spent 45 minutes trying to get the car to turn off. If it says shift to park the car will not shut completely down and there is nothing that can be done. I spoke with gmc for 30 min and was finally told to unhook the battery because they have no way to make it shut off without going to a dealership which was closed at the time.

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

Shifting car into park and the car does not register that it is in park. Display reads "shift to park" and lights do not shut off. Car will sit for 15 or more minutes before the car registers it is actually in park. I try to start it, shut it off, of start it, put in gear and then switch back to park and shut it off but still reads "shift to park". Battery is going to die if this keeps happening. GMC should be responsible for doing a complete recall on this, especially since they are aware of the problem. I have been stranded in parking lots waiting for this car to correct itself. this has been going on for over 4 years.

After shifting to park and attempting to turn off my vehicle, I receive an “Action Required Shift to Park” error message. I’m assuming the vehicle is in park but I’m not certain and worry about it moving or rolling. It is difficult to get it to turn off by jiggling the shifter and turning the vehicle on and off. At times, I am not able to get it off and then the vehicle will not lock and the battery goes dead. According to my VIN there is not an active recall but brief internet search states there has been numerous reports, recalls, and lemon law returns due to this.

The vehicle keeps shaking specially at the first and second gear, up to 40miles/hr and at any up hills roads. I took it to the mechanic and he said that it’s an issue in the transmission and needs to be replaced. Also the engine fan randomly turns on automatically, and a warning message stating “Steering assist reduced. Drive with care”
