The largest single group is the driver assist & collision avoidance.
Across this model's run it ranks 7 of 18 worst.
The letter says how bad. This says what kind — whether this year drew
an unusual number of complaints, unusually dangerous
ones, or failures that arrived unusually early.
The dashed ring is 50 — the national norm. Further out is worse.
Complaint volume — 16
Against the median year of the Buick Enclave. 50 means typical for this
model; 100 means roughly double.
Severity — 91
17.5% of these complaints
involved a crash, fire, injury or death, against a national rate of
9.7%.
Early failure — 100
100% of failures with a mileage on record happened under
36,000 miles, against a national rate of

When owners complained
A spike years after the car went on sale usually means a part wearing
out on schedule across the whole fleet — the kind of pattern no single
owner can see from inside their own car.

NHTSA investigations into the 2025 Buick Enclave
An investigation is the step before a recall: the agency has seen enough
complaints to look into a pattern itself. An open one means it thinks
something may be wrong and nothing has been fixed yet.

Electronic Brake Module Component Failure
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 th...

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.

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 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.

POWER TRAIN
My wife's 2025 Buick Enclave with less than 10,000 miles (around 9,800) stranded us on the highway. Transmission was shuddering and felt like we were hitting rumble straps on acceleration. Then, we couldn't go over 18 mph, then it just stopped. Couldn't even pull off to the side of the road because the electronics wouldn't let the vehicle go into neutral to allow us to push it onto the shoulder. Eventually we got it off the Interstate to a residential area. When tow truck arrived, they couldn't get it into neutral and had to drag it onto the wrecker with generous amounts of WD-40. That can't be good for the vehicle. The vehicle is at Randy Wise Buick in Fenton, Michigan. We were lucky not to have been hit on the Interstate. Biggest worry is not the transmission problem but that we couldn't even push it off the roadway.
