2025 Buick Enclave

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.

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.

The wireless charging tray on my Enclave gets the phone very hot. It gets so hot that my phone shuts down. This happens with Pixel, Samsung and Apple devices. There are several reports on the web regarding this issue. I even tried to charge my phone without a case same issue. This is a concern because it can cause a vehicle fire. The batter gets so hot that it can easily catch on fire

The contact owns a 2025 Buick Enclave. The contact stated that while attempting to switch lanes, the blind spot indicator on the passenger’s side mirror failed to illuminate to signal a nearby vehicle or object. 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.

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.

The contact owns an Evenflo Safety Seat, Model Type: Revolve Extend 360 Rotational All-in-One Convertible Car Seat, Model Number: 25701756, manufactured in October 2022. The safety seat was being utilized in a 2025 Buick Enclave. The contact stated that while driving at approximately 35-45 MPH, the vehicle was T-boned by another vehicle on the passenger side. The air bags did not deploy. The safety seat was located on the rear driver's side, and another safety seat was on the rear passenger's side; however, the rear passenger's side safety seat showed no visible signs of damage. There were no passengers in the safety seats. The contact stated that the rear driver's side safety seat was in rear-facing position, but after the crash, the safety seat had rotated to forward-facing and had separated from its detachable base, landing on its back. The contact sustained mild whiplash and received medical attention. A police report was filed. The vehicle was towed to a tow yard but not yet deemed totaled. The contact related the failure to NHTSA Action Number: AQ24001 (Child Seat). The safety seat manufacturer was not made aware of the failure.

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.

I had it towed to a local GMC /Buick service department. My safety and the safety of others were put at risk if the car did not brake. Could have led to a crash. The problem has been confirmed by the dealer. They indicated the Brake Master Cylinder needs to be replaced. ( 7/28/2025 I was told it was on back order, when available is unknown) Warning lamps etc have been described above. I had just pulled into the driveway of a friend and got all the warning lights.
