Buick Envista Acceleration problems by year

It was in the shop 9/19/24 for the screen going blank while driving causing a safety concern as was unable to tell how fast was going, screen slowly came back on and they found had internal fault and replaced telematics control module. All was fine until July 2026. Picked up from Glen Polk GM in Gainesville Texas 7/15/26 they state reprogramed radio, and USB file. The screen went out 7/19, 7/21, 7/29. 7/31 we dropped car back to dealership 7/31 and they kept it until 8/4/26. This time they state the repair...

See attached document for complaint.

On January 15, 2025, my front panel went completely blank (black screen) moments after driving off a parking lot. I pulled over, turned the car off to try to reset it, but didn't work. Tried this 3-4 different times in different locations. I also had no exterior lights working. My main lights, brake and headlights were not functioning. This was very stressful and luckily it was still daylight, so I returned home immediately. I took a video of this incident for my records. Next day, the panel is working properly.

While driving down the road to work on the expressway both my screens blacked out couldn't see my speed and then came back on it did this multiples times on my 30 minute drive to work one way and multiple times on my 30 minute drive home. It's done this for the last week. It's very scary to know you can't see your speed or don't know if your car is suddenly going to shut off going down an expressway that people are going 75 mph and could hit me. It shows my vin is not part of the recall but is doing exactly what the recall is describing.

The instrument panel intermittently blacks out during vehicle startup or while driving. I haven't had my vehicle for 30 days and it's happened many many times, almost caused an accident due to the distraction it has caused. No warning signs prior to the screen blacking out. Service calibrated/reprogrammed the radio but issues have continued. I have several photos and videos of the numerous times this has happened.

The Cruise control do not adapt to the speed of the vehicle in front of me like it's supposed to and all of sudden windows won't go up or down. Car is falling apart even though it's new how is that possible.
