“While getting an oil change at my Gmc dealer they discovered that a rear brake pad was separating from the back metal plate it was attached. They said it was a serious safety issue. They said it was a manufacturing issue and not the result of wear. The dealer said the car should not be driven. They did not have the repair parts so I took it to tuffy muffler who fixed it. They confirmed it was due to a manufacturing issue.”
NHTSA complaint #11352883, filed 2020-09, 30,000 miles“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. …”
NHTSA complaint #11396267, filed 2021-02, 34,300 miles“When the car is shifted into park, the dashboard shows a warning that the car is not in park. I have to move the shifter back and forth before the car registers that it's in park. Happens on nearly every occasion that I turn my car off.”
NHTSA complaint #11206079, filed 2019-05, 18,000 miles“I have been having issues with the Gmc Acadia's shift to park function. On a daily basis while driving, when I stop the car and shift it into park, take my foot off the break, and turn off the ignition, the car beeps continuously and displays a message that the car is not in park. I typically have to turn the car on and off multiple times or pump my foot on the brake multiple times for the message and sound to clear. The car has even continued to roll forward a few times as well when shifted to park and the ignition off.”
NHTSA complaint #11351858, filed 2020-08, 41,000 miles“I place vehicle in park and the computer does not recognize so the bell comes on. I have to go in and out of park several times before it engages. This occurs when I am turning the engine off, I first place in park then push the ignition to shut off. We had a prior issue where the emergency brake was on, auto backed in a driveway with slight incline, and when we tried to disengage it was simply stuck, we called to tow the care; once driver arrived we went through the release one more time and it finally released. Since that time, I never use the parking brake. …”
