The sunroof exploded without warning. Driving 57 MPH on a 55 MPH road, it was a sunny day, there were no cars around me and there were open fields on both sides of me. My daughter (17-years old) was starring up at the sunroof when the sunroof exploded.....And it sounded like a gunshot. Manufacturer would not warranty the sunroof as I could not prove the glass was not broken by an object.

Driving at 30mph and all the dashboard lights turned on and all the warnings kept popping on the dashboard and 30 seconds later the brakes were not working when I was approaching a busy intersection. I was able to pump the brakes and stop the vehicle and put it in park and the vehicle shut off and nothing would work - not even the hazard lights. The vehicle is currently at the dealership being assessed.

I was driving and a variety of failure warnings popped up on my screen along with a total brake failure, unable to stop, had to coast until the vehicle was no longer moving. No accident resulted, but it could have been very serious. Mechanics diagnosed it as a loose battery cable.

The Automatic Emergency Braking (AEB) system activates unexpectedly and dangerously. Incident 1 5/7/2026: While driving approximately 2 mph in a drive-thru and rounding a curve, the vehicle suddenly applied full braking without warning. The braking force was severe enough that I struck my face on the steering wheel and my child was thrown forward in a secured car seat. Incident 2 5/19/2026: While merging onto a busy road behind a semi truck, the vehicle again applied sudden hard braking after I safely merged. This caused the vehicle behind me to nearly rear-end me, creating a high-risk traffic situation. These events occurred with no obstacle or reason that would justify emergency braking. In addition, the vehicle developed a coolant leak around 20,000 miles, raising concerns about overall reliability and potential related system issues. The unexpected braking presents a serious safety hazard and increases the risk of rear-end collisions and injury. The vehicle is being brought to a dealer for inspection, but the issue is intermittent and may not be easily reproduced.

The brakes make a squealing noise when backing up and this has been reported on many 2025 enclaves. There is also a repeated clicking noise after turning the vehicle off.

The contact owns a 2025 Buick Enclave. The contact stated that while driving at an undisclosed speed, the cruise control mode became inoperable, and the vehicle unexpectedly shut off. The contact also stated that while driving at an undisclosed speed, messages related to the braking system, forward collision system and the ABS were displayed. Additionally, the ABS was inoperable during inclement weather, and the vehicle became unsafe to drive. The contact pulled over to the side of the road because children were also inside the vehicle. The contact’s husband then drove the vehicle to the dealer, where the failure was duplicated, and several diagnostic trouble codes were retrieved. The dealer informed the contact that the failure was a known issue and that several technical service bulletins related to the failure had been issued. The vehicle was not repaired. The contact stated that the vehicle was unsafe to drive and posed a risk to the contact and other drivers. The manufacturer was made aware of the failure. The failure mileage was approximately 15,000.

The car frequently just slams on the brakes on its own when reversing. Doesn’t matter the speed, and nothing is behind me at all. It also triggers a check engine light with transmission errors if you get a car wash and it is even mildly cold. Transmission errors when it gets too cold or snow in the grill.

This happens every single day, not just today, but are two separate issues related to my brakes. 1- squealing brakes. Every single day and for several miles before they warm up. The first time I brought this issue to the attention of the dealership, they replaced the brakes, and there was no squealing for just a few days. I forced the dealership within a week to let them know, I had to bring it back in, and they said they were fine and would just squeal. To this day, I have no idea if this is safe or not, but haven’t been able to receive a message that they squeal for any specified reason, which does not ease safety concerns. 2- my app told me that I had only 18% brake pad life remaining when I was around 11k miles. I took it in and they said they just reset the sensor without fixing the brakes because they didn’t know why it was doing that - its now clear to me that this isn’t an accurate reflection of true brake life measurements and is most likely just based off of miles driven instead of a true measurement, as advertised. I love this car, but am super disappointed that my brakes are so consistently loud - it’s both embarrassing and worrisome. And to make the dealership aware and just have them reset a sensor for this completely separate concern is honestly obnoxious.

1EA26006 · Electronic Brake Module Component Failure
Opened Aug 21, 2026 · No close date supplied
Status: open (inferred from source dates) · Service Brakes
On April 11, 2024, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE24011 after receiving complaints concerning a loss of brake assist in 2023 MY Cadillac Lyriq vehicles. These complaints allege a hard brake pedal, followed by a “Brake System Failure” message at start up or while driving. GM shared records regarding several internal investigations for loss of brake assist due to alleged spindle fractures in the eBoost system. GM has stated that in the event of a spindle fracture, anti-lock brakes (ABS), stability control, and traction control remain functional until the vehicle comes to a complete stop. At this point, ABS, brake assist, stability control, and traction control functions are lost. The loss of these functions causes the vehicle to set one of three Diagnostic Trouble Codes (DTCs) based on failed performance criteria for the Electronic Brake Control Module (EBCM). These DTCs, in turn, activate several driver alerts: an audible chime, a visual “Service Brake System” message in the display, and multiple illuminated Malfunction Indicator Lights (MILs) for the ABS, Traction Control, and Brakes informing the driver of loss of functionality. The vehicle speed will also be limited to 70 KPH (43 MPH). Since opening PE24011, ODI has continued to receive reports of loss of brake assist. Some of these reports describe symptoms inconsistent with GM’s description of a spindle failure. These reports allege an immediate loss of brake assist functionality as opposed to the loss occurring after the vehicle comes to a complete stop. The sudden loss of brake assist during a braking event could result in extended braking distance, which increases the risk of a crash or injury. ODI believes further analysis is necessary to assess the potential for failures in GM’s eBoost system to resulting in safety-related outcomes. At this time, ODI is aware of the following vehicles that are equipped with this eBoost system: 2023-2026 MY Cadillac Lyriq, Chevrolet Colorado, and GMC Canyon; 2024-2026 MY Buick Enclave, Envision; Chevrolet Blazer EV, Equinox EV, Traverse; Cruise Origin; and GMC Acadia; 2025-2026 MY Cadillac Celestiq and Optiq. ODI is also aware of 2024-2026 MY Acura ZDX and 2024-2026 MY Honda Prologue vehicles that were built with this system. The Acura and Honda vehicles were manufactured by GM in a joint venture with Honda, and will be included in the Engineering Analysis as peer vehicles. ODI is opening this Engineering Analysis to further assess the safety-related consequences of a failed eBoost system. In addition, ODI is expanding the scope of the investigation to encompass all GM vehicles that share this eBoost system.
