2015 GMC ACADIA Engine Problems

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...

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. *TR

IMMEDIATELY AFTER FILLING THE TANK WITH GAS, I STARTED THE ENGINE AND IT ACCELERATED TO FULL CAPACITY. THE ENGINE HAD MADE CLICKING SOUNDS, AND OTHER SOUNDS WHEN IT STARTED.

DRIVING AT 34-45 MPH LOSE ALL ENGINE POWER AND HAVE TO PULL OVER. VEHICLE TOTALLY LOSES ALL POWER. ENGINE SHUTS OFF.

AFTER PICKING UP OUR NEW TRUCK WE NOTICED THAT THE VEHICLE'S ENGINE WAS SHORT JUMPING AT LOW SPEEDS, ESPECIALLY WHEN IN TRAFFIC - AT FIRST WHEN THIS OCCURS YOU HAVE TO ALMOST ASK YOURSELF DID I HIT THE GAS PEDAL INSTEAD OF THE BRAKES. AFTER ONLY A COUPLE WEEKS OF OWNERSHIP WE DROPPED OFF OUR NEW VEHICLE TO BE REPAIRED. DEALER 'S GMC CERTIFIED TECHNICIAN HAD TO CONSULT WITH GMC CORPORATE TO HELP TROUBLESHOOT AND THEN DECIDED TO REPLACE THE LOWER AND UPPER ENGINE VALVE COVERS, AND THE TRANSMISSION CONTROL MODULE; WHICH WAS A QUICK FIX THAT LASTED A LITTLE OVER A WEEK. NOW OUR BRAND NEW VEHICLE IS ONCE AGAIN A LEMON AND REPEATING THE ORIGINAL ISSUE. AFTER CONTACTING GMC AND AFTER REQUESTING ANOTHER SAFER NEW VEHICLE SINCE ITS COMMON SENSE THAT A BRAND NEW TRUCK SHOULD NOT HAVE ANY INTERNAL ENGINE OR TRANSMISSION PROBLEMS BEING THAT WE HAVE...

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.
