With my vehicle stationary and shifter in the park position, i turn my car off and the vehicle turns off but the instrument cluster says "action required - shift to park". this message also does not allow the day time running lights to turn off and if the lights don't turn off the battery drains if parked for long stretches. i have to turn the car on/off several times before it engages and the message disappears.
Tl* the contact owns a 2017 gmc acadia. while driving approximately 25 mph, the brake fluid low and brake indicators illuminated. in addition, the brake pedal traveled to the floorboard and did not stop the vehicle. the vehicle was taken to suburban cadillac of troy (248-643-0070, located at 1810 maplelawn dr, troy, mi 48084) where it was diagnosed that the master cylinder failed and caused brake fluid to leak into the booster pump. the manufacturer was made aware of the failure and the contact was not called back. the vehicle was not repaired. the failure mileage was approximately 37,500. *bf*jb *ln*jb
Shift to park issue as described by others. gm dealer says it needs to replace a $20.00 harness + labor of over $200.00. "service parking brake" issue that randomly presented itself one day. i was unable to use the parking brake. gm dealer had to "upgrade" my ebcm for a whopping $200.00. how does gm think the consumer should have to pay for this. they have a monopoly because they are the only ones that can fix this!

We have had numerous issues with the cars brakes automatically locking up when something triggers the collision safety break. specifically when crossing rail road tracks after a train has past. as a result the car stops completely and automatically while on railroad tracks and won't allow you to move. you have to put the car in park, wait (on railraod tracks) and then attempt to move but it may activate it again so you have to do it again. meanwhile you are on tracks, with cars behind you honking and screaming. this has happened numerous times, reported it to our dealer, service and gmc corporate where nothing was done. they said they would put in a "black box" like device but never did. it is a major safety concern for my family and one that gmc is not addressing adaquately.
I was driving my 2017 gmc acadia on the highway with my son in the vehicle when it slammed on the brakes for no reason. when i first took it to the dealership they did not believe me. they researched the issue then informed me that gm was aware of the "phantom braking" problem and issued a bulletin to the dealers. they said the way to fix it was to reboot the computer. they would not give me a copy of the bulletin that showed the issue or the fix. gm knew this was happening in their vehicles and they did not tell the car owners. it is a miracle that it did not cause and accident and that no one was hurt or killed. i do not feel safe driving this car but they will not let me out of my lease early.
Parking brake failed to engage--was told by dealer the modular for the parking brake system failed.vehicle was stationary at the time
Was found brake fluid in the brake booster vacuum hose and brake booster is leaking from master cylinder and being drawn into the brake booster .
Vehicle had multiple (more than 2) warning lights flashing on and off, while rpm and mph needle would fluctuate simultaneously. this would happen while in the driveway and also while in motion. vehicle would not accelerate with accelerator pedal fully pressed, especially on an incline. while this was occurring i had to exit the highway and turn around in an adjacent subdivision. i could not get out of the way of a car in the neighborhood because i was trying to go forward on the street due to a slight incline. it would also jerk into gear when moving from reverse and drive. had this happened in a traffic intersection, it would have been deadly. this car is unsafe. after 6 months of being 'fixed' it has started happening again. the dealership has had the vehicle for a week this time without being able to fix it. the last time it was at the dealership for around 10 days.
The vehicles brakes became defective and stopped working which caused an accident.
Engine feels like its going to stall when stopped at stop signs or red lights. the car lunges forward when in park on an incline.
This issue has happened 3 times now and is becoming a safety concern for my family and i and for others on the road. i purchased the car brand new in may 2017 and the issue occured for the first time on october 02, 2017. second time was february 15, 2018 and the third time happened around early april 2018. while driving at a slow speed (entering a parking lot, in the middle of an intersection when i was about to make a left turn on a green light, and while driving in a parking lot after getting gas) the car made a grinding/clunking sound and was brought to a very abrupt stop. i tried to press the gas but the car would not move. i changed the gear from drive to park and then drive again and would still not move. i turned the car off and then back on and still nothing. i ended up figuring it out by pressing the parking break button 1-2 times and was then able to proceed to drive. it seems as though something may have triggered the parking brake but while i was in drive and while the vehicle was moving. i was almost rear ended when this happened in the intersection and also during the time i was unable to move in the intersection, my light had changed to yellow and then red and oncoming traffic was honking because they could not go on their green light due to me being stopped in the intersection. it was very scary and dangerous as it almost caused an accident 2 out of the 3 times it has happened. i told service dept at the dealership about it twice. they have "looked into it" one time but since they were not able to replicate the issue (obviously), there is nothing they can do. i am concerned about my families safety if this continues to happen.
Stopped at an intersection for a red light, upon green light, accelerator tapped to enter intersection and forward collision braking system applied brakes. nothing was in front of vehicle at time of forward collision braking system application. tapped accelerator again and vehicle hesitated but slowly accelerated to normal speeds. the vehicle behind at the time barely stopped which would have rear-ended my vehicle and caused a chain reaction. continued on to work, carefully applying accelerator after each stop. very scary for the vehicle to stop in the middle of a busy intersection with traffic behind and not immediately allowing driver to control acceleration.
