2023 GMC Acadia Owner Complaints

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.

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.

I am experiencing a recurring P04FB diagnostic trouble code on my 2023 GMC Acadia, related to the crankcase pressure sensor. GM issued Bulletin No. PIP5841C, which attributes the issue to moisture buildup freezing inside the sensor. Their recommended fix is to remove the sensor, blow out any moisture, and reinstall it. However, this is not a permanent solution—the code returns within days, suggesting an inherent design flaw in the PCV system. Additionally, the replacement sensor (Part #12718935) is on national backorder, making it impossible to obtain. Many owners across multiple GM models using this engine (such as the Chevrolet Blazer and Cadillac XT4) are experiencing the same problem, yet GM has not provided a real solution. A properly designed PCV system should not allow excessive moisture to accumulate in the sensor. Instead of addressing the root cause, GM’s bulletin merely delays the issue by temporarily clearing the moisture. This approach does not prevent the problem from recurring, and it does not fix the underlying defect. If the sensor fails or provides inaccurate readings, it can affect emissions and engine performance. The fact that the replacement part is unavailable suggests GM may be restricting access to it, possibly because they know it is defective. This raises concerns that GM is quietly managing a widespread issue rather than issuing a formal recall or warranty extension. I am requesting that the NHTSA investigate this issue, as GM's current approach does not resolve the problem. Owners should not be forced to repeatedly clear moisture from a sensor that is failing due to a design flaw. If GM has internally identified a better solution, it should be made available to affected owners instead of delaying action with ineffective temporary fixes.

I purchased my 2023 Arcadia FFWD SLT a few months ago used with 11,000 miles. During the past few months I have noticed when reaching a speed of 45-60 mph the vehicle vibrates. I took the vehicle to the dealership on 10-10-24 and they said they could not find anything but they did not do an intensive problem search. I am concerned the problem may be related to a transmission recall dated 6/23. I did a search but no recalls came up my VIN but the vehicle has a major vibration when going 45-60 mph.

Car's back up camera screen has gone black on several occasions. The vehicle has been in the repair shop , this is my fourth time trying to get it repaired. The screen goes black with a red circle and triangle on the screen when the car is put in reverse. This makes backing up difficult because of the vehicle size and blind spot . This problem developed in the first month of having the vehicle and again the vehicle is back in for repair the fourth time for the same issue I've had the vehicle in service for eleven months.

Whenever the vehicle's windshield washer is used the smell of the fluid enters the vehicle. This is particularly acute when the HVAC system is used at the same time. Since the label on the washer fluid container says the fluid is poisonous and the vapors are harmful and cannot be made nonpoisonous, I feel I should report this. I have had 4 GMC representatives confirm this is indeed happening. One rep was the Field Engineer Supervisor. All of this is documented as I have had this examined 4 times at the request of the GM customer service representative.

While driving under normal conditions, the vehicle experienced a sudden, violent deceleration. The emergency braking and collision avoidance systems activated spontaneously, as if the vehicle had struck or was about to strike an object. There was no obstacle, impact, or external threat present. This uncommanded braking caused significant physical stress and injury to the occupants. Critically, multiple safety systems failed during the event: The seat belts did not lock, failing to restrain the occupants; The airbags did not deploy, despite the severity of the deceleration; no warning indicators or diagnostic alerts were present before or after the incident. These failures directly contributed to physical injuries, including TBI (concussion, spinal trauma, etc.) which required emergency medical treatment and ongoing care.
