general problems of the 2015 GMC Acadia

The engine is not shifting properly, and the vehicle loses speed while driving and hesitates to accelerate. At time, it feels as though the car is not moving at all. This issue has occurred on multiple occasions, affecting both me and my family, and has forced us to pull over because the vehicle could barely move forward. This happed once on the highway and almost caused an accident. Additionally, the check engine light remains on at all times.

I was curious about recalls because I totaled my 15 Acadia slt2 and when I hit the impact didn’t deploy airbags and I had no idea until after my accident that they were recalled!!! this incident totaled my Acadia caused my face to be slammed into my steering wheel, cutting me in 2 places and shattering my eye glasses. I now have a scar that looks like a 2nd chin from my impact to hitting the steering column! what should I do? I wasn’t or hadn’t received anything from GMC about this recall until recently and damage has already been done and I’m at a loss of tremendous amounts because my air bags could have saved $300+ glasses and doctors appointments etc….

My vehicle has a severe launch shudder in 1st gear from a stop, and while driving along when I’m in 4th gear, or during the 2-3 upshift or 3-2 downshift. It shakes the entire SUV so bad I have to stop accelerating. The vehicle becomes uncontrollable which is a major safety risk.

2nd time ac compressor motor breaks and as is in line with the serpentine belt, all other systems including electrical and engine stop working. Poor engineering or other reason causing part to break down.

Today I encountered a problem with my vehicle that not only put myself at risk but my children. This problem came out of no where since I have not had any problems with my vehicle before today. When going to leave I turned my car on to have it stall and die. I had someone come out and look at it and got it to work by pushing down on the gas pedals. Said nothing looked wrong since there were no check engine light or any codes coming up on the dash. So I proceeded to leave and go get gas. When going to start my car again it stalled yet again and showed a check engine light. The car then started to smell like smoke and gas to where I immediately turned to car off and had my kids get out. I then tried to start my vehicle again and thankfully was able to get it to work with the check engine light showing. I called the car dealership that I go to for my oil to let them know I’m coming and that it stalled again with the check engine light showing. I made it to the shop and they ran diagnostics on it to show that it was a time change in the engine that was messing up. They then proceeded to let me know that I would have to go to a GMC shop because they can’t do the work at their shop. He then proceeded to tell me not to drive in this because the car will stall in motion and will not go faster than 45 without dying or shutting off. Which to me is a major safety concern since I have to drive it to the shops and let along home with my children in the car. So the whole way I couldn’t go over 45 without my car starting to stall and shake. Thankfully it didn’t shut down with my kids in the car on a main road.

I just purchased this car three months ago, the a/c is no longer blowing cold air. The air blows but not cold and the heat works just fine. From what I've read online, this appears to be a common issue on this make and model. Please address this. .

Every time I go to the gas station after filling up my truck with gasoline, my vehicle will not start up right away. I have to press the gas pedal lightly in order for it to start up. This just started recently.

When you turn traction control on the entire car shakes. Windshield wiper fluid will not come out. Passenger window will not roll up from driver control. Tire pressure monitor system has been out for time. This car is not that old for it to have all these issues.

On 4/11/18 we took the car to the dealership for a side dtection alert. Was informed that the right side module needed replaced. We declined service due to cost of $628. 01/2019 we were have problems with the car starting. Last week multiple warning a messages started appear on the dashboard as the car was traveling and stationary. Took the car in for service and diagnoses was the right side detection model had severe corrosion and the left side model also had corrosion. Parts where not available so we drove the car home. Next day same issue with multiple warnings and alerts on the dash. My wife was able to make it home and after turning off the car it would not start even after charging the battery. Next day had the car transported to the dealership. After disconnecting the side sensor models, the car restarted and started functioning normal. Obviously this is a big saftey concern for a vehicle that is less than 4 years old, less than 50k miles, garage kept and well care for.

Service stabilitrak--traction control off! message, then car ran rough and lunged on acceleration. This happened at 5,000 miles, repaired at dealer. Again about 12,000 on a trip and reset itself. Now, at 20,000 miles sames message and is at the dealer being repaired. This is a safety hazard. Please investigate this.

Bad shifting in transmission when you slow down or come to a stop and turn right and accelerate at the same time. This happens on the 2014 and 2015 models, tranmission will stutter and abruptly shift into a lower gear. On the Acadia forums it is documented by other owners as well (approx 30-50 other owners). The transmission needs a reprogram to account for this issue. Gm appears to not be doing anything about this common issue.
