Vehicle does not recognize that it's in park. Once parked a warning comes on telling you to shift to park. The vehicle does not completely shut off because it does not believe that it is in park.

Cars emergency brake locks up for no reason. Happened on several occasions but last instance burned out actuator and locked up calipers from just sitting on a hill with foot on brake. This is a huge safety issue when it locks up for no reason on a road. It-??s stranded me at least twice because it-??s hard to undue.

The contact owns a 2018 GMC Acadia. The contact stated that upon depression of the brake pedal, the brake pedal was depressed to the floorboard without warning. The contact had taken the vehicle to a dealer where she was informed that the brake pads and all four rotors needed to be replaced. The contact then called Brad Deery Motors (112 N. 2nd St, Maquoketa, IA 52060) and was informed to take the vehicle in to be diagnosed. The contact was then informed that only one of the rotors needed to be replaced. The vehicle was repaired however, the failure persisted. The contact also stated that upon attempting to park the vehicle, the shift to park warning message would illuminate on the instrument panel. The contact had to repeatedly shift the vehicle in and out of the park before the vehicle would recognize the shifter in the park position. The manufacturer had been notified of the failures but offered no assistance. The vehicle was not repaired. The failure mileage was approximately 46,000.

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. That occurred approximately 9/20/2018..

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.

Since the beginning of October, there are times that the car doesn't register that it is in park. When the car is turned off, there is an alert that comes up on the display saying to put the vehicle in park. It isn't every time the engine is turned off, but it can sometimes take up to four or five tries to get the car to register that it is in park. I shift to park, turn the car off, get the alert. So I turn the car back on, shift to a different gear, and than shift pack to park and turn the car off. And repeat this until I stop getting the alert. When it is put in park, the car will shift slightly if I get this error. I've started using my emergency break whenever I get out of the car to make sure that it won't roll.

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.

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.

GMC Acadia will not register when the driver shifts the gears into park. An error message 'shift to park' is shown on the dashboard even though the gear is in park. The driver is unable to turn the car off because of the error message. It takes several turns of switching the car on and off and flipping through all the gears in order for the message to disappear so that the car turns off. The car was taken to the dealer on June 26 for repairs and has been sitting there over a month because they are unable to correct the issue.

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.

The contact rented a 2018 GMC Acadia. While the contact's friend was driving 40 mph, the engine revved and the vehicle accelerated on its own. The brakes failed to stop the vehicle. As a result, the vehicle drove through a partition and crashed into a brick wall. The air bags deployed. All four occupants in the vehicle were injured and received medical attention. The contact suffered chest pain, another occupant sustained a cut on the head, and the other two occupants suffered fractures. A police report was filed. The dealer and manufacturer were not contacted. The cause of the failure was not determined. The vehicle was destroyed and towed to a tow lot. The failure mileage was unknown...
