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

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.

The contact owns a 2023 GMC Acadia. The contact stated that the vehicle was taken for maintenance, and the tech informed the dealer that the passenger’s side rear suspension toe link needed to be replaced. The vehicle was taken to an independent mechanic who confirmed that the passenger’s side rear toe link needed to be replaced. The vehicle was repaired. The contact stated that no warning lights were illuminated. Upon further investigation, the contact related the failure to Manufacturer's recall number: N222364330; however, the VIN was not included. The manufacturer was not made aware of the failure. The failure mileage was 42,101.

Mileage: 42,101

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.

Mileage: 39,000

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.

Mileage: 5,200

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.

Backup camera failed. Same issue on 2021 Acadia SLT Needs to be investigated on 2023 models

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 fr

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 opt
