Transmition makes jerking motion while driving. During driving the transmition will shutter and make you feel as if the car is going to stop running.

Fixed: We got all parts fixed by Chevrolet dealer in Archbold. They confirmed issues presented in Ashtabula and fixed the problem. There was no cause to the issues, only faulty parts. Warning lights: Check Engine light turned on and Check Stablitrak came on during the issue.

Low oil pressure warning, engine shutoff. Vehicle was equipped with oil life monitoring. It was at 20%, when engine shutting down. Engine seized, called tow truck. Towed to shop. The only report was to the dealership and the repair shop. Possible high oil consumption. The warning was last minute, barely had time to react.

Multiple AC system failures - Rear evaporator core failed in summer 2020. Had the unit replaced at a the dealership. Nine months later the front evaporator core failed. From discussion with numerous mechanics these parts should not be failing. Vehicle has less than 40k miles on it and I am the original owner.

Air conditioning hose rubbed/melted from being too close to the engine frame. Had it replaced in 2019 by dealership. Now it is happening again in 2021 and dealership says the bracket for the engine needs tightened so it doesn't keep occurring. It will cost over $2000 to get this fixed again. Air blows hot air in rear and passenger side ac vents and driver side is getting warmer as well. Air doesn't not blow cold when stationary or while driving.

With only 49000 miles on my 2016 GMC Acadia, my check engine light came on, I took it to the dealership the next day and they told me that I had to replace my gas pedal...I have owned numerous other vehicles and never once had I have replace my gas pedal. This is a huge safety concern because according to the service adviser if not replaced it may cause my vehicle to accelerate without me pressing on the pedal.

Ac was blowing hot at less than 42K miles. It happened out of the blue when I pushed the ac button it would just blink, light would turn off and it would blow hot air. There was no warning of a leak or anything wrong before this point. The dealership found the issue to be 'leak combination manifold line rubbing against R/F body beam'. it was necessary to replace A/C combination manifold in addition to evacuating and charging the ac combination lines and it cost almost $900 for this repair. I should have leaking ac hoses or rubbing against the manifold with mileage this low.

On Saturday (8/31/2019), I noticed that the ac in my 2016 Acadia (about 79,000 miles) wouldn't turn on. My vehicle has two evaporators, one in the front for the front ac, and one in the rear for the rear ac. They are connected by an aluminum tube (GM part #23199274). When I took the vehicle into the GMC dealer, they showed me that a connector on the power steering fluid (psf) line, which runs beside this aluminum tube (see photo 1), had rubbed up against the aluminum and worn a hole in it, allowing all the refrigerant to leak out (photo 2). There is supposed to be a little rubber piece that fits over and protects the coolant line (you can sort-of see it in the pictures), but that piece is small and slides down, exposing the aluminum tube. The technician then told/showed me how he usually bends or moves the psf line so that it doesn't rub against the aluminum coolant tube. This indicates that GM is aware of the issue and has done nothing in an attempt to fix it, even though this inherent design flaw allows the entire coolant charge to leak into the atmosphere. Needless to say, since refrigerant is not exactly environmentally friendly, I find it concerning that GM is apparently aware of this issue and hasn't taken the necessary steps (like a voluntary recall) to fix it. I called the GM customer service line and made them aware of the situation, and they said "there is nothing they can do." I'm hoping this complaint forces them to resolve the issue and stop leaking full refrigerant charges into the atmosphere. Note that this would also be an issue if the situation were reversed and it was the ac coolant tube that chafed through the psf hose. If the psf connector was even 1 cm off, then hypothetically the coolant tube could rub through the psf hose and cause a failure of the power steering system. It is also desirable to avoid this as well, for obvious reasons.

There has been a couple of instances where the car just shuts off once when turning into a parking space, and once while sitting at a roundabout and then I have to put it in park and then turn it back on. It seems to work for a while after that, but it is extremely frustrating for a car that is not that old and I just got it.

My key is stuck in the ignition and will not release on my 2016 GMC Acadia. The battery had to be replaced because it was completely draining my electrical system. It has been determined that my car is not recognizing it is in park to release the key. The floor shifter needs to be replaced according to my GMC dealership. This is extremely dangerous as the car could drift at any time, not to mention the strain on the battery.

It is a shame that some other older cars like Ford receive infotainment upgrade modules to support google and apple car play and GM did nothing so far

The screen mentions the stabilitrak isn't working and the truck looses power and shuts off. The transmission isn't shifting properly. The truck looses power out of no where al so saying the traction control isn't working. It happens all at random times.

My 2016 GMC all wheel drive both front wheel bearing went out at 26,000 miles there should be a recall on these. There are really bad

My wifes vehicle which is our family vehicle has had several reoccurring issues. We have brought the vehicle to the dealership several times and have not resolved the problem as it is still on going. The problem does not happen all the time but is extremely scary. While driving the vehicle will alert that you are about to have a collision but there is nothing in front of you just a vehicle to the side of you and will break on its own. This has happened numerous times but the dealership has not been able to replicate the problem. We also had service stabilitrak, traction control off and the service traction control lights come on the dash while driving. When these came on the vehicle started to shake horribly and the RPM's dropped to under 1000 while still going 40 mph. I have also had on a few occasions the backup camera say vehicle guiding lines unavailable while reversing and while driving randomly the vehicle with say park assist off then disappear after several minutes. Just 2 weeks ago I went to start the vehicle and it said service theft deterrent system and would not start until I disconnected the battery and waited a few minutes to reconnect the battery and re-start the vehicle. We brought the vehicle to sheehan GMC in lighthouse point Florida 4 times for these specific issues and received no resolution. After contacting GMC we received no assistance until I filed lemon law which then they sent an engineer who stated after a 2 hour inspection there was no replication of problems and vehicle is operating as normal. This vehicle is a death trap and not safe to drive my family in. I will not purchase another GM product.

On multiple occasions the vehicle has completely shut-down, while sitting stationary in traffic with the brakes applied (once at stoplight, another time backing out from driveway with brake applied prior to transitioning to drive) each occasion the vehicle was restarted with no issue or warning lights. 1st time taken to dealer, no "codes" were found and were unable to re-create problem, and sent home. Currently at dealer for the 2nd time and still unable to retrieve error codes or re-create. Currently contacting GM for assistance. Vehicle purchased new in December 2016 from North star GMC in Pennsylvania, and currently has less than 10K miles.

This vehicle lack proper load restraints so that objects placed in the cargo area do not fly all over and hurt passengers in case of sudden stop or accident. Cargo netting has very poor side anchors and lacking floor anchors.
