Check engine light came on first and then the infotainment went blank for three days. Took to dealership for the software update which shut the infotainment system down completely.

We experienced a spontaneous sunroof explosion. Vehicle was towed to the dealership. Sunroof is being replaced under warrenty. The vehicle is presently stored underroof at Barkley GMC, Tuscaloosa, AL. After the very loud explosion, I pulled to the side of the road and engaged On-Star for a wrecker. There were no warning lights... just a spontaneous explosion ... blew out the entire sunroof.

I was driving on the interstate and the car just shut off. I was on the left lane and cars were honking and tailing me as I was trying to get off. I could not get off on the left and had to drift across to the right side. Thank God it was downhill. I drifted to the exit and went off onto the grass. My safety was at risk to the fullest. I am very lucky I was not killed as well as my sister! It was the most frightening experience. The car was towed to Pensacola Step one dealership. The manager of service says it needs a new engine. The car is only 6 months old! No warnings until it shut off, the gas peddle didn't work and I don't remember what it said I was a wreck.

Completely lost all power brakes while on the road today. Owned it for about 11 months. Looking like the master cylinder. We've been having random electrical issues when we're cranking it up. Weird sound coming from the dash when the AC is on on occasion. Like the car wasn't fully kicking over even though the engine was running. Sometimes turning it off and turning it back on would make it work.

I wanted to update a previous report. The vehicle had had some odd electrical issues. The brakes ended up failing while driving but no electrical issues at the time proceeding it. What I wasn't able to report before was that the brake pedal sunk to the floor with no effort to stop the vehicle at all. The emergency brake is a button on the left side of the vehicle which was attempted to be engaged to stop. It made no effort to stop whatsoever. The vehicle is a danger to society. I just got it back from the dealership and they made an update to the computer or console but replaced no parts. These all need to be recalled no one should be driving these.

as someone who has been in the car business his entire life, the below TSB is utter bullshit. My 2025 enclave with 3400 miles on it had a catastrophic and copious amount of transmission fluid. on my tile floor in my garage and all over my driveway a minimum of 5 to 7 quarts.. had my wife been driving the car with my grandchildren as a guarantee it would’ve locked the transmission up and evacuated all the oil as it is on the high-pressure side of the pump. Based on my knowledge of recalls, this should be a stop sale and a recall, not a TSB why have they been given a pass on this? https://static.nhtsa.gov/odi/tsbs/2025/MC-11014291-0001.pdf

Super Cruise system malfunctioned and is available for inspection. The vehicle came close to colliding with a guardrail as explained below. Since I believe the issue is not with the vehicle itself, but with Road Information used by Super Cruise, I have reported this to GM Customer Service but not to a dealer. Monday August 25, 2025 Canada – Nova Scotia and New Brunswick While driving on Super Cruise (SC) at 75 MPH in the right lane of a 4 lane freeway (2 lanes each direction), three times the vehicle attempted to enter a non-existent right lane, driving onto the right shoulder and heading for a guardrail. In each case SC warned me of the lane change with normal alerts of seat vibration, right turn signal activation and the DIC display showing an image of a right lane, in green, indicating the lane was safe to enter. However, in each case there was only a partial lane or no lane at time the vehicle crossed the white line. I was alert, and surprised of its action which I did not initiate; and before taking control I waited about 3 seconds to see if SC would stop the maneuver and return to the proper lane. But in each case the vehicle entered the shoulder and appeared to continue, getting close to a guardrail. •The 1st incident occurred on Nova Scotia Hwy 104 at exit 29 where the vehicle attempted to enter the entrance lane at the point where it ended, at 9 AM ADT. •The 2nd incident occurred on New Brunswick Hwy 2 at exit 211 where the vehicle attempted to enter the entrance lane at the point where it ended, at 12 PM ADT. •The 3rd incident occurred again on New Brunswick Hwy 2, at exit175 where the vehicle attempted to enter the exit lane at the point where it ended at, 12:30PM ADT. Weather was sunny and dry with good visibility. Traffic was extremely light. I have since driven on SC approximately 400 miles without incident. And since most of my driving is on freeways, I have probably driven on Super Cruise for over 4,000 miles without incident.

The failure occurred intermittently. The vehicle was taken to the dealer four times; however, the dealer was unable to determine the cause of the failure. The mirror was replaced; however, the failure persisted. The manufacturer was informed of the failure and informed the contact that the mirror was designed for the sensor to activate within a certain proximity, and if the vehicle or object was not within that range, the driver would not receive a signal. The contact was referred to the dealer, who confirmed that the indicator was working intermittently. The failure mileage was unknown.

Driving down the street after a short trip this morning with no one on the road in front of us the vehicle had an alert like we were about to impact someone and braked pretty hard 2x back to back with the collision alert popping up. The person behind us had to slam on their brakes and BARELY avoid hitting us. There was NOTHING in front of us. This vehicle is dangerous to everyone around us and should be taken off the road.
