  AIR BAGS

  The contact owned a 2025 Buick Enclave. While the contact’s daughter was driving through an intersection on a green light at an undisclosed speed, a truck crashed into the front driver’s side of the vehicle. Upon impact, the air bags failed to deploy. The contact and his wife and daughter were all transported for medical attention and were checked for injuries. The contact received a CT scan and was currently undergoing physical therapy and pain management injections for back and hip injuries. The contact’s wife underwent CT scans, and the daughter was awaiting an MRI result following the follow-up with the primary care physician. A Police report was filed, and the vehicle was deemed a total loss by the insurance. The vehicle was towed to a tow lot. The dealer and the manufacturer were notified of the crash, and the manufacturer provided a case number. The failure mileage was approximately 14,300.

  SERVICE BRAKES, ELECTRICAL SYSTEM, STEERING

  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.

  SERVICE BRAKES, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING

  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.

  SERVICE BRAKES, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING

  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.

  FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, SERVICE BRAKES, HYDRAULIC

  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.

  POWER TRAIN, BACK OVER PREVENTION: REARVIEW SYSTEM BRAKING, LANE DEPARTURE: BLIND SPOT DETECTION

  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.

  SERVICE BRAKES

  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.

Might be related to PIP6005 or CSP N242473580) How was your safety or the safety of others put at risk? Not being able to take off from a stoplight could have been easily rear ended. Had it broke a came to a complete stop on the interstate, my wife and kids could have been killed from high speed impact at the rear of the vehicle could have life impacting injuries or death. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Inspected by Dealer Don Hewlett Chevrolet Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? None at all

  ENGINE

  What component or system failed or malfunctioned, and is it available for inspection upon request? The engine and/or powertrain system catastrophically failed while the vehicle was in motion on the freeway. The vehicle lost power, shut down, and became disabled. The vehicle is currently in the possession of the Buick dealership and is available for inspection upon request. How was your safety or the safety of others put at risk? The failure occurred while driving my husband and children in fast-moving freeway traffic. The vehicle suddenly lost power and shut down, forcing us to coast to the shoulder while traffic was moving around us. This created an extremely dangerous situation that could have resulted in a serious crash, injuries, or fatalities to my family and other motorists. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. The Buick dealership confirmed the engine failure and advised that the vehicle needs a replacement engine. The vehicle was towed directly to the dealership following the incident and was declared inoperable. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others? The vehicle has been inspected by an authorized Buick dealership service department. The manufacturer (GM/Buick) has been notified, and a corporate case has been opened. Were there any warning lamps, messages, or other symptoms of the problem prior to the failure, and when did they first appear? Yes. Multiple warning alerts appeared immediately before the shutdown, including critical warnings such as low oil pressure and instructions to turn the vehicle off. Moments later, the vehicle lost power completely and shut down.
