The DASHBOARD keeps changing while driving, and the dealer states they have fixed it. I have had 2 dashboards replaced since I purchased the car (1 year) and this unsafe while driving my GPS keeps changing while driving. This is VERY UNSAFE! The SUNROOF WILL NOT CLOSE, until the next day. It rains inside my car because it will not close, so I can not use my sunroof PERIOD. This is one of the reasons I purchased the car. NOW, my CHECK ENGINE LIGHT is on for EMISSIONS SYSTEM (IT IS CRITICAL THAT YOU TAKE CARE OF THIS PROMPTLY TO MAINTAIN SAFETY). The dealer held my car for 3 days, and now they state "they requested the part, but no one told them (from the manufacture) that the part is not available due to problems with the current part and they have to rebuild the part, and it's on back order". Now, I'm riding around with a check engine light on until Nobody knows when! I don't trust this dealer, who told me its okay to drive like this AND we will call you when the part comes in. They stated they fixed my dashboard and its still not fixed. They don't know when, they will have the part for my sunroof or my emissions issue, and my dashboard is still not working and I have to borrow someone car to travel because my GPS and Engine light is on. A brand new car and it has been in the shop (6 times) more than any car I have owned. I pay my car not on time and I keep my car serviced, but this not fair to me and I need help please.

Only had car since March and already had 2 issues. First, I had a check engine light in early May and took it to the shop and the problem was identified as a cracked fuel pipe. Had to wait almost 3 weeks for the park to finally get delivered to the dealership and was able to get fixed on 6/12/25. Then on 7/17/25 check engine light came on again. According to the Buick app, it was coming from my emission/evap system again. Took it the dealership on 7/21/25 and as of 7/27/25 it is still in the shop and they were unable to determine what is causing it. They have reached out to GMC which told them to do a ECU program reset which still didn’t rectify the issue. Already has been in the shop for a week now.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING

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.

Vehicle: 2025 Buick Envista Sport Touring Mileage: Under 5,082 miles Issue: Rear side window trim detachment I am reporting a rear window trim detachment that occurred after my 2025 Buick Envista Sport Touring went through a brushless automatic car wash. The driver-side rear window trim completely detached, and the passenger side is now partially detached. The detached piece was found inside the wash tunnel, confirming it came off during the wash. The trim is made of thin black metal and has sharp edges. The remaining trim is at risk of detaching during normal highway use, especially since I live near railroad crossings, and drive in Florida weather conditions including heavy rain, humidity, and heat. Automatic car washes operate at 1,000–1,200 psi, far exceeding any natural wind or rain conditions. This shows that the trim’s adhesive is not strong enough for routine car maintenance, even when used as intended. There was no warning in the owner’s manual advising against automatic car washes. Because the trim is in a blind spot, I cannot monitor it while driving. The dealership told me to retain the loose trim until replacement parts arrive, but that is unrealistic and unsafe. If the trim detaches at highway speed, it could become road debris, potentially hitting another vehicle or causing an accident. I have already reported this issue to the manufacturer, and it is being processed as a warranty repair. However, I was instructed to ensure the loose trim doesn’t fall off, as the dealership is required to return it to Buick. This expectation places unreasonable responsibility on the driver, despite the fact that the part is already failing under normal conditions. This is not cosmetic — it is a safety issue caused by insufficient adhesive or trim design. I respectfully request NHTSA investigate whether this defect warrants a Technical Service Bulletin or recall.
