GMC Complaints

We purchased this vehicle New in 2018. Gear Shift Problem. The vehicle displays a persistent “Shift to Park” warning on the dashboard. This usually occurs even when the gear selector is in the “Park” position and I have difficulty in Turning Off the Vehicle. The ignition remains active despite the gear selector being in “Park.” We have to go through all the gears - Drive - Neutral then Park then try to turn it off over and over. May take 5 or 6 tries before I can leave the car safely. Unintended Vehicle Movement: We believe the car is safely in the “Park” position and have exited the car and then it rolled. We have to jump back in and try to turn it off. I'm [XXX] and husband [XXX] and this is causing us injuries. It rolled one time and hit the Handicap Parking Sign in my parking space. It just missed hitting another car in a parking lot when it rolled about 3 times now. Called around to get it fixed but everyone says "it's been a problem for years and GMC has NO fix for it." Only temporary fix is to install new gear shifter or full transmission replacement, which owner has to pay for $700 to $3000 repair! We don't have 30,000 miles as of yet. We are low income, on Social Security and this should be a Recall since there are many complaints online for years. Praying we do not have a collision or terrible injuries.

Rear tailgate randomly opens on its own while driving. Items from the rear bed can fall out causing a traffic hazard

Transmission started to shutter at 24000 miles. Dealer said couldn’t find anything. ABS and Stabilitrack light came on at about 40,000 miles off and on. Both these problems could result in a crash. On freeway or streets. The display information/ radio has a mind of its own. Connects to any phone number or start the on star call and etc. it takes your attention off the road and can result in a crash.

check engine light comes on & simultaneously the A/C will not work. when I first researched there was information stating that the grease GM used in the drive train was too thick resulting in the thermostat not working properly. even though GM first acknowledged they caused the problem they are not issuing a recall to fix the problem. instead they want me to take my car to a dealership & pay approx. $2400 to turn off the sensor

Thermometer stop properly working. Check engine light came on. Ran fhe diagnostic code which confirms the Thermometer needs replaced. This began Dec 2023 - bought the vehicle in Oct 2023. Unsure if this was an issue prior. The cooling fan would kick on, and the temp gauge would stop working. Dealership was able to replace this and so far no further issues with the tempature reading.

Shift to park alert pops up when turning vehicle off. Vehicle is in park. This prohibits the vehicle from turning off. Per my investigation other gmc acadias made in 2017 also have experienced this which results into either prohibiting them from turning their vehicle off or their battery dying. This is a safety hazard because it increases risk of being stranded due to malfunction.

AC condenser went out on my vehicle with 100,000 miles, lots of reviews online stating this is a known problem but yet there is no recall. Torch Converter going out at 80,000 miles.

The vacuum pump seized causing the breaks to not work, brake assist not working code shows. The pump was replaced and after a week the same issue happened (vacuum pump seized) breaks are not working again.
