2012 GMC ACADIA Complaints

The power liftgate suddenly collapsed while I was standing underneath it. It dropped on top of my head pretty hard as it was a sudden drop of the liftgate. My safety was/is at risk and has caused injury to my head. Currently experiencing headaches. As condition progresses, I will be seeking medical attention. It is available for inspection. I have recorded a video of the problem. The problem is recurring and reproducing. I have not taken it to a dealer or independent service center today (9/13/2021 date of incident) as the weather is bad in my area (experiencing high rain and winds from a tropical storm). I will have it taken in on 9/14/2021. The vehicle has not been inspected by anyone. There were no warning indicators or other symptoms prior to the initial collapse.

The brakes on the vehicle have failed 5-7 times within the past year and a half. By "failed" I mean that the pedal was touching the floor of the vehicle and did NOT engage. Mechanic was unable to replicate the failure any of the three times we took it in to get it looked at. The brake pads, rotors, and fluid lines have all been checked multiple times and are all in good condition. The master cylinder was replaced and the brakes worked well for about 6-7 months. Approximately 3 weeks ago, the brakes failed entirely, yet again, this time driving on a highway at 70mph. The emergency brake had to be used in order to get the vehicle to slow down. The vehicle was then dropped off at a local dealership, who has kept it for about 2 weeks and states that they cannot replicate the problem when they take it for a test drive. We have 2 young children and this has been our primary family vehicle. There has not been a check engine light or any other warning lamp AT ALL.

THIS VEHICLE IS SHOWING ON DASH THAT ( SERVICE AIR BAGS) WHY WOULD THIS TAKE PLACE? IT HAS 175,238 MILES.IS THIS A RECALL OR WHAT? --- PLEASE ADVISE -- THIS COME UP ABOUT TWO WEEKS AGO.

Was waiting on dealership to catch up to bring in for a transmission problem. I know it is transmission related due to not wanting to shift properly and the fact my friend has same make and model only about 100000 more miles than mine does was doing same symptoms and she took to 3 or 4 mechanics and all said nothing wrong..no codes show up...needless to say after about 2 months it stalled out on her on interstate with speed limit 75 and she barely moving. I myself was at a sharp curve in turn lane waiting on traffic and when I braked to stop it made horrible sound and felt like brake was pushed through floorboard. When I was clear to go i push accelerator down to the floor and am barely inching along and am now stuck in the road in a 90 curve where its hard to see traffic coming. This was very scary and traumatic having this happen. I'm just glad it was only myself and the other drivers were being observant and paying attention to the road. This has happened a lot compared to research on blogs car complaints websites. The common problem is it doesn't give a code when diagnostic checked. 99% of cases show they best guess or find something else wrong and you pay 3 or 4 charges until you finally convince them its the transmission and then you're out 5000. Not counting the average 4500 you've already pd due to not listening to the driver of their vehicle and causing unnecessary charges and leaving you without a vehicle too long that isn't necessary.

Driving at 55mph, suddenly the Traction Control blinks on & off, the vehicle starts skipping. Next, Service Stabilitrack System appears and I almost come to a complete stop, Engine Running at Reduced Power appears. I barely made it to the side of the road, traffic was heavy at the time. This is apparently a common issue with other Owners and could be a number of different sensors, parts malfunctioning.

My air conditioning stopped working and the power steering line got so hot that it melted a pinhole in my AC line so all the freon would leak out. the power steering hose is so close that when it gets hot it melts the aluminum air conditioning line. The only way to fix it is to buy a aftermarket line and splice it together with the damaged a/c line. And the safety Hazzard is that if you're in hot car,you'll be more tempted to pull out in front of someone because you need to get some air. If you look at the setup you will see the engineer made a mistake, that's why they changed the design in later years,I think they should be responsible for making such a preventable mistake.

When the rear lift gate gets to the full open position, it immediately falls down causing a safety hazzard. Luckily no one was in the way when this happened. I haven't had it inspected yet and there are no warning lights or messages. It is available for inspection upon request.

Drl sockets melted safely issue A service bulletin was issued but not a recall , gm will now not fix it unless I pay 2,600 This is a fire hazard

A P0306 CODE APPEARED. I TOOK IT TO MY MECHANIC AND HE EXPRESSED THAT MY ENGINE WAS 'POROUS'. WHEN I START MY ENGINE THERE'S A ROUGH START. WHEN IT'S IDLE THE CAR SHAKES.

WHEN IT IS PARKED AND IDLING IT SOUNDS LIKE IT WANTS TO STALL. WHEN I AM DRIVING IT IT SHIFTS HARD AND THE TRANSMISSION STARTS SLIPPING. I TOOK IT TO A REPUTABLE MECHANIC FOR AN ASSESSMENT OF THE PROBLEM AND HE SAID HIS COMPUTER SAID THAT IT WAS THE TRACTION CONTROL MODULE IN THE TRANSMISSION AND THAT IT WOULD COST ABOUT $1500 TO REPAIR IT INCLUDING LABOR. HE CALLED THE DEALER TO SEE IF IT WAS IN STOCK AND THEY SAID THEY HAD MANY OF THEM. I WOULD ASSUME THAT THEY WOULD NOT STOCK A $700 PART IN THAT QUANTITY IF THEY WERE NOT HAVING QUITE A FEW PROBLEMS WITH THIS PART. OTHER SUV'S HAVE BEEN RECALLED AND I WAS WONDERING WHY MINE WAS NOT. I WOULD APPRECIATE IT IF YOU COULD LOOK INTO THIS MATTER FOR ME AND GET BACK TO ME WITH AN EXPLANATION. THANK YOU FOR YOUR TIME AS I MAY BE GETTING STUCK SOMEWHERE WITH MY WIFE AND CHILDREN IN THE CAR..
