See attached document for complaint.

To the Vehicle Safety Complaint Division: I am filing a safety complaint regarding brake service performed on a 2025 Buick Envista (VIN: [XXX]) by Suburban Buick GMC of Troy, 1850 W Maple Rd, Troy, MI 48084, an authorized GM dealership. Safety Issue: The vehicle was brought in on XXX with brake pulsation at 20,689 miles. Suburban performed rotor resurfacing on all four rotors and certified the repair as complete and verified on XXX. On XXX — 13 days after Suburban certified the repair — Moran Buick GMC of Sterling Heights found the rear rotors causing the identical brake pulsation symptom. [XXX]'s service advisor determined the rear rotor was rubbing against another component and stated in his professional opinion that Suburban's prior service caused the condition. The corrective repair was processed as a GM warranty claim. Safety Concern: A certified brake repair on a 21,342-mile vehicle failed within days of service. The failure involved the braking system — a safety-critical component. The original service manager dismissed the customer's safety concern by stating failure would depend on "how you drive." Dealer: Suburban Buick GMC of Troy, Registration Number XXX, operated by Lithia Motors, Inc. (NYSE: LAD) Supporting Documentation: Two authorized GM dealer repair orders documenting the failed repair and corrective service are available upon request. I respectfully request confirmation of receipt of this complaint and assignment of a case or reference number. I am available to provide any additional documentation or information required to support this complaint. The complete documentary record, including both repair orders, the independent inspection findings, and the complete correspondence record with Lithia Motors corporate, is attached. Sincerely, [XXX] Authorized Representative for [XXX] [XXX] [XXX] Attachments: — [XXX] v.

Vehicle: 2025 Buick Envista Incident Date: July 19, 2025 I purchased a brand-new 2025 Buick Envista in June, 2025 and owned it for just over a month when the brakes suddenly and completely failed while I was driving on the highway. As I exited the ramp and attempted to slow down, the brake pedal went soft and unresponsive. I had no ability to stop my vehicle, and in a moment of panic, I swerved into a curb to avoid hitting other cars or pedestrians. This caused damage to my rim and tire, but thankfully I avoided a major crash or injury. I had the vehicle towed to the dealership, where they diagnosed a master cylinder failure. The car is currently being repaired under warranty, but I no longer feel safe driving it. I suffer from anxiety and have been experiencing panic attacks and nightmares since the incident. I am deeply afraid of getting back into a car that nearly killed me. This is a brand-new vehicle and a brake failure of this magnitude should never happen — let alone within the first month of ownership. GM/Buick has offered to repair the car but not replace it, and I was informed I do not qualify for lemon law because this has only occurred once. That doesn’t change the fact that I experienced a catastrophic and life-threatening failure that could have resulted in serious injury or death. I am filing this report because I believe this is a manufacturing defect that poses a danger to others. A single failure of this kind is enough to destroy trust in the safety of a vehicle. If this happened to someone else, the outcome could be tragic. Please investigate this issue before someone loses their life.

I have not yet taken it to be checked. I will soon. The rearview camera has gone out completely, it still beeps if I am too close to something. Sometimes the infotainment screen does like a crossover screen malfunction type of issue. This put myself and others at risk because I rely on the camera and although it beeps, I still would not be able to see what is behind me. There was nothing the warned or indicated there was an issue. This is a brand new vehicle so not even sure why this would have occurred on such a newer vehicle.

Wiper blades are not compatible with after market brands due to wiper arm design. Exterior trim. The rear quarter window trim has poor adhesive. Causing chrome panel to bend and detach while vehicle was one highway.

The contact owns a 2025 Buick Envista. The contact stated that while driving during heavy rain, the windshield wiper fractured in half, resulting in poor visibility while driving. The vehicle was taken to an independent mechanic, but the part to repair the vehicle was unavailable. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 15,266.

On August 13, 2025, I purchased the 2025 Buick Envista from DeMontrond in Houston, Texas, for $31,000.00, with a down payment of $12,000. The car is a gift to my grandson who recently graduated from college and starting a job at the Emory University Hospital. On September 6, 2025, the car had to be taken to be repaired due to a “fuel filler pipe leaking”. I didn’t expect that a brand-new car would need to be repaired for something that seems to be dangerous. The fuel filler pipe is crucial for the safe and efficient transfer of fuel to the vehicle's tank. It connects the fuel cap to the fuel tank, ensuring that fuel flows properly without spills or leaks. A leaking fuel filler pipe can lead to fuel vapors escaping, which can be dangerous and illegal in most states. It can also cause issues with the vehicle's EVAP system, leading to diagnostic trouble codes related to fuel vapor leaks. I contacted General Motors Consumer Department and sent a letter to Mr. Mark Reuss, President of GM requesting that the vehicle be replaced or the money I paid be refunded. They refused to replace the vehicle or refund the money I had already paid. Through this letter, I am requesting your help to have GM recalled the vehicle and that I am provided with a brand-new and safe replacement or to refund me the money I already paid.

ON [XXX], (SUNDAY) AFTER DRIVING TO AN EAST LANSING, MI RESTAURANT & SPENDING 1-1/2 HOURS EATING BREAKFAST, I TURNED MY CAR ON AT ABOUT [XXX], AND RECEIVED AN ERROR MESSAGE ON THE DASHBOARD THAT THE POWER STEERING WAS NOT FUNCTIONING. I TRIED BACKING UP, THEN DRIVING FORWARD 3-4 TIMES & THE ISSUE WAS CONFIRMED. I ALSO TURNED THE CAR OFF & ON SEVERAL TIMES WITH THE SAME ERROR MESSAGE APPEARING. I CALLED ON STAR AND THE DIAGNOSTIC TESTS WERE ALL NEGATIVE FOR ISSUES. MY CALL TO ON STAR GOT DISCONNECTED. I TURNED MY CAR OFF. WHEN I TURNED IT BACK ON, THE POWER STEERING WAS WORKING. ON STAR CALLED ME BACK & I REPORTED THAT THE POWER STEERING WAS NOW APPARENTLY WORKING. I THEN DROVE, VERY APPREHENSIVELY, OVER 100 MILES TO MY HOME IN GRAND HAVEN, MI WITH NO PROBLEMS. THIS COULD HAVE PROVED DEADLY IF MY POWER STEERING HAD FAILED DURING THE DRIVE. ON [XXX], (SUNDAY), AT 3:22PM EST, I RECEIVED , IN MY EMAIL, MY SEPTEMBER 'DIAGNOSTIC' REPORT THAT MY ANTILOCK BRAKING SYSTEM HAS AN ALERT THIS MONTH WITH REQUIRES IMMEDIATE ATTENTION. AS OF TODAY, MONDAY, SEPTEMBER 15, I HAVE NOT CONTACTED THE DEALER YET. THIS IS MY 3RD WARRANTY ISSUE SO FAR, MAKING ME EXTREMELY UNSATISFIED (NOT YOUR PROBLEM, I KNOW). MY BACKUP CAMERA CEASED FUNCTIONING & HAD TO BE REPLACED. MY DRIVER SIDE MIRROR GLASS WAS NEVER SEATED PROPERLY AND THE ENTIRE MIRROR IS IN THE PROCESS OF BEING REPLACED.

I was driving on a Chicago expressway with my family when the tire pressure light came on, within 3 mins and before we could safely pull over the tire shredded and eventually the entire middle part of the tire came off and we were thankful there was a lot of traffic so we had to slow our speed because the inner part of the tire came off and it rolled to the side of the expressway. This could have been catastrophic if another car on the expressway tried to avoid or hit the rubber part of the tire while they were driving. We had to backup an on ramp because there was no safer alternative. We were able to put on the spare and find a tire shop that was affordable to replace the tire.
