2023 GMC Acadia Problems, complaints & recalls

On [redacted] my Acadia started flashing dash lights and messages and had significantly reduced engine power and power steering. This caused it to come near to a stop in the middle of the [[redacted]] eastbound span. There is no area to pull over so I limped the car the rest of the way at 20 mph with hazards on. Vehicle was leaking oil and had camshaft trouble codes. I took it to a mechanic and was told it should go to a GM dealer because it needed major engine work. The dealer replaced the oil pan and other...

The back windshield randomly made a loud pop out of nowhere and completely shattered while I was driving in my car with 2 people in the backseat. This put everybody safety at risk bc the glass popped and shattered into the vehicle. There were no objects thrown at the vehicle and nothing hit the back window at that time.

My 2023 GMC Acadia has a toe link issue in the rear suspension. This is according to the GMC Service Department in Marquette MI. Is this a possible safety issue, I really don't know. It does make a horrible clunking sound when I steer sharply which vibrates the car. So I definitely believe this does affect the steering. No question I will have to get this fixed ASAP.

Vehicle Information: 2023 GMC Acadia VIN: [[redacted]] Description of Safety Defect: While operating the vehicle, a sudden and total loss of propulsion occurred without warning. The transmission completely disengaged from the drive gears while the vehicle was in motion. When depressing the gas pedal, the engine freely revved up to approximately 3,000 RPM, but no power or torque was transferred to the wheels, leaving the vehicle entirely stranded and unable to move. This severe mechanical failure matches the exact...

While driving my 2023 GMC Acadia, I experienced intermittent abnormal brake pedal behavior. When applying the brakes normally, the pedal would travel partway and then suddenly encounter resistance/catch accompanied by a click, causing the vehicle to brake abruptly and unexpectedly. The vehicle remained straight, but the braking action was significantly harder than intended. This problem has created a serious safety concern. On one occasion, the unexpected braking behavior nearly resulted in my vehicle being...

I find the location of the lower gear shifters + and - to be physically far away from a driver's normal reach, making a driving hazard. If you want to change gears as is typical in mountain driving in steep descents, the driver has to lean awkwardly away from all mirrors and standard driving position making it a potentially hazardous situation for the driver and occupants to be in. It has nothing to do with comfort, but rather normal functionality, keeping the driver and their attention unadjusted on the road,...

I was driving on the highway, and the sunroof was closed and the cloth screen that would allow or not allow sun to come through was also closed. Then out of nowhere there was this explosion sound which scared me so much, I almost wrecked the car and at first, I thought maybe someone shot at my car and shot one of my windows but as I got to the side of the road I realized that none of my windows in the car had been shot and that it was the sunroof and I noticed that cause pieces of glass came into the car from the...

Infotainment system freezing, screen shaking, touch screen not working, disconnecting from android auto, unable to connect to phone.

My 2023 GMC Acadia consistently makes a sound at lower speeds when it is changing gears. For example, accelerating or accelerating for stoplights. The sound is kind of a ka clunk. The technician can find nothing and does hear the sound when we go for a test ride. I am worried that the sound indicates a transmission problem. The VIN search does not show a recall for my vehicle.

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

Telematic control module went out. On research, it is a common problem and there is no fix because the module is back ordered. No time given for when available.

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.

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...
