ELECTRICAL SYSTEM
My 2023 GMC Acadia experienced a complete electrical system failure while driving on an interstate highway. During the incident, the vehicle lost all electrical power, including hazard lights and steering assistance, and could not be shifted into neutral. The vehicle became immobile in active traffic and required police-ordered towing due to safety risk. This incident was the second alternator failure within six months. The second failure involved a GM-installed replacement alternator that failed prematurely. Both incidents required towing, and the second created a significant roadway safety hazard.

SERVICE BRAKES, SEAT BELTS, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
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.

The contact owns a 2023 GMC Acadia. The contact stated while driving 55 MPH, while attempting to depress the brake pedal, the contact heard an abnormal sound coming from the brakes. A dealer and independent mechanic were contacted. No warning light was illuminated. The vehicle was taken to an independent mechanic to be diagnosed, and the contact was informed that the brake pads wear was uneven on the driver’s side and the driver’s side front caliper needed to be replaced. The vehicle was then taken to the dealer where it was diagnosed; however, the result was not provided. The brake pads were replaced; however, the caliper was not yet replaced. The manufacturer was notified of the failure, and informed the contact to take the vehicle to the dealer for assistance. The approximate failure mileage was 39,000.

STRUCTURE
The contact owns a 2023 GMC Acadia. The contact stated that after purchasing the vehicle, it was discovered that there was water and condensation inside the rear middle brake light assembly. The contact later discovered that during rainstorms, rainwater had leaked into the rear seating and hatch area of the vehicle. The vehicle was taken to the local dealer who determined that the failure was due to a manufacturing structural error and the vehicle needed body work to be performed to correct the failure. The vehicle was not yet repaired. The manufacturer was notified of the failure. The failure mileage was 5,200.

UNKNOWN OR OTHER, FUEL/PROPULSION SYSTEM, ENGINE
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.

VISIBILITY/WIPER
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.

Since late 2023/early 2024, I started to notice that my liftgate was open, while the Acadia, a lease with less than 15K miles, was parked in the driveway, off. At first, I thought it was a mistake on our part, that we had accidentally hit the button on the remote to open it or had forgotten it open. As time went on, the incidences continued and I realized it was happening on its own, while the car was off! When the Acadia was at the dealership this fall for a warrant repair (a pump that GM knew was problematic but only has alerts out about for now), I mentioned the liftgate. Thankfully, the problem happened at the dealership too so workers could witness it. It's a major safety issue and a public safety issue. When the pump repair was occurring, I got a text from the dealership that the problem with the liftgate was my fault, that how I clean the inside of the car had affected the mechanics and that I would be on the hook for over $300 in repairs. I had no way to prove otherwise and opted to instead disable the open function using the dial on the driver door set to off and it has not opened. Fast forward to last week and GM has a recall on GMC and other pickups where this kind of issue appears to happening to tailgates and it instantly felt similar. I believe GMC Acadia's have the same faulty wiring and I should not be on the hook for this repair but GM should fix the problem.

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.

We purchased a 2023 GMC Acadia AT4 new in October 2023. There is currently a little over 19,000 miles on the AT4. As of today November 13, 2024 the SUV has been to Blaise Alexanders, for at 3 times with same issues. Between the speeds of 50-65 there is a shudder, which in August 2024, the Chevy garage changed the fluid However, You can now feel this at any speed through out a trip. The SUV was return to the shop for increasingly worse shudder between 50-65 and a new issue of "hunting" between 25-35. There are times that the SUV does not want to propel forward (like the AT4 cannot get out of its own way) Also, when making a sharp right turn followed by an immediate left turn, onto uneven surface, the AT4 acts as though it is confused as to what gear it should be. The garage was then notified that I know have whining sound. At one point the garage had the AT4 for a week, the general manage drove it, did not feel anything. I then returned, took him for drive and he felt it. Left the car for him to take one of the "transmission" repair individuals out on a drive with the scan tool hooked up. Results of that test drive---"the car did it once, slightly but it was not picked up on the scan tool." Troy, from the service desk informed us they called GM to have their traveling engineer come look at the AT4 in a few day. GM's representative stop at the garage, DID NOT look at the car or speak to us, but has Troy tell us to keep driving the car. We are now in November and unfortunately, I got a little behind on bugging them due to the loss of my brother, father and step -father. But then again they have made no attempt at resolving this issue. This is frustrating. We are asking for any assistance that you can provide. I find it hard to believe that we are the only individuals that are experiencing these issues. I love my car. Why did they change the fluid if nothing was wrong the first time?? It has progressively been getting worse and winter is coming......

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.

Today is Aug. 24, 2024. On [XXX], as my wife and I were preparing to leave on a vacation trip, our leased 2023 GMC Acadia would not move out of Low Gears moving forward. I soon discovered that it also would not shift into Reverse. When I took the vehicle to the GMC dealership near my home in Grand Rapids, Michigan, the service advisor told me that the Check Engine light was on. The dealer has had the car since the date of this occurrence, on [XXX], giving me a smaller car as a loaner. My service advisor told me that he was able to get the car into Reverse. When I have called, he tells me they are trying to identify the problem. I see on the Internet that this model of vehicle has had multiple "transmission issues" and that there has been a Recall due to the transmission. I have not been alerted to a Recall. Yesterday, on Aug. 23, I received an Onstar Diagnostics Report saying there is a "diagnostics alert" requiring "immediate attention." I leased this vehicle in October 2023 from Todd Wenzel Buick GMC, where the vehicle now is located in the Service Department.

BACK OVER PREVENTION: WARNINGS, BACK OVER PREVENTION: REARVIEW SYSTEM BRAKING
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.
