general problems of the 2023 GMC Acadia

Vehicle would not run due to a failed fuel pump control module. With a non-running engine, the transmission could not be placed into neutral to be able to movie vehicle out of the road. Needed tow truck to move vehicle. This condition placed many people at risk as the vehicle could not be moved out of the way until a tow truck arrived.

Temperature gauge dropped to zero or no reading, message displayed on screen "steering assist reduced, drive with care", continued to drive speed limit, when parked fan runs after car is shut off, in a few days the temperature gauge started working again, then the cycle repeats about once every 2 weeks for a couple months before engine light came on last week & when checked at a local parts place was told temperature sensor malfunction. Read multiple accounts of this same issue online.

The contact owns a 2023 GMC Acadia. The contact stated that with the stop/start feature activated and while attempting to park the vehicle, the accelerator pedal was slightly pressed in order to slowly move the vehicle forward. The vehicle suddenly experienced unintended acceleration and drove forward, over a curb, and crashed into a tree. During the crash, the front end of the vehicle sustained severe damage, but no air bags deployed. No injuries were reported, and no police report was taken. The cause of the failure was not determined. The contact indicated the failure had occurred on multiple occasions. The local dealer was notified of the failure. The manufacturer was not yet contacted. The failure mileage was 5,665.

From the day that I’ve gotten this vehicle it has been burning oil and water like crazy. There is no reason I should be putting a quart of oil every couple weeks.

I've had the engine stall before coming to a complete stop on several occasions. It also has been shifting hard and has had a delayed shift. The other day all of the lights to to screen and speedometer completely went out while driving then randomly came back on. That's the only speedometer I have is the digital screen.

On 11/26/24 my wife was running errands in her vehicle when the power shut off and killed the car. She was in the left lane of a busy state highway. She was able to coast off the road slightly before the vehicle came to a complete stop. The dashboard said to press brake and start button, but the car would not start. The vehicle was also stuck in drive and would not switch to park, neutral, or any other gears. Police came and had to push her vehicle with theirs into a nearby park lot so a tow truck could pick it up. It is currently at a gm dealership waiting to be looked at.

The contact owns a 2023 GMC Acadia. The contact stated after his wife had driven 75-80 mph in the highway, she made a turn towards his residence. The contact stated that while his wife was attempting to pull in the driveway, the vehicle shut off inadvertently. A message indicating a transmission failure and other unknown warning lights were illuminated. The vehicle failed to restart after several attempts. The vehicle was towed to the dealer, where the failure could not be duplicated. The contact stated that the vehicle had been at the dealer for four months. The manufacturer was notified of the failure, but no assistance was provided. The vehicle was diagnosed or repaired. The failure mileage was approximately 6,250.

Shortly after leasing the vehicle in December of 2022 I noticed the transmission would slip when accelerating. It also jumps when down shifting as I'm slowing down - as well as after place the car into drive. I did bring the vehicle back to GMC in early 2023 explaining the aforementioned. I was told that there was too much transmission fluid which was the causing the issues I was experiencing. They reduced the fluid levels and sent me on my way. Unfortunately their assessment and solution did not remedy the problem. I intend to bring the vehicle in again, but based on past experience, I will be told nothing is wrong. Lastly, I've done some research and it appears I'm not the only person experiencing the same issue. I'm hoping that reporting this issue will lead to an investigation of potential safety issues.

Purchased vehicle oct. 21 2022. In first week, vehicle left my wife stranded twice, and myself once. When error occurs, vehicle goes into limp home mode and cluster illuminates all lights, says serivce brakes, transmission, engine, fuel tank reads "e" (when is was just full), prndl buttons are flashing and will not allow park, does not respond to throttle inputs. . . Only way to be not stranded as the vehicle will not restart is to disconnect battery or wait 15-20 minutes as the vehicle seems to incorrectly "heal" its errors and allow the engine to restart. I noticed this when the tow truck came to pick it up, and he "drove" it on to the flat bed. 45 diagnostics showed up on the scan tool, all relating to can bus communication. My concerns are the following: 1. How can a 2023 vehicle with <400 miles leave some one stranded 3 times because of a can bus comm error? there is an electrical gremlin (likely from lack of quality control) causing to leave a customer to having to limp to the side of the highway. 2. Why is the error able to incorrectly "heal" itself, ie. The fault reactions seem to debounce and allow engine to restart (as mentioned prior) after a certain amount of time. This only leads to potentially putting the customer back at risk as they just were. 3. Gm dealer is yet to start troubleshooting, its been 2. 5 weeks. Claim is that they "need a transmission guy to look at it since the codes causing the check engine light are transmission module". Although, the vehicle has approximately 45 active codes, relating to many different modules and all pointing to can bus error. The vehicle has an electrical issue, causing my wife to get stranded. First warning on cluster before being stranded : "service: transmission now unable to shift soon. " what does this even mean???? this does not tell me, what the problem is, and what I should do about it. I am an experienced obd engineer from an auto oem and this does not follow best practices. Please help.
