NHTSA Complaint #11575789 — 2022 CHEVROLET TAHOE

Transmission Failure/Windshield Wiper Failure- While traveling approximately 48mph, the vehicle completely locked up. Tires screeched, vehicle came to a grinding halt. Two of my children were in the vehicle (15yrs and 7yrs of age.) This was sudden and without warning! The vehicle almost rolled, and we were lucky that no vehicles were behind us or we would have been rearended. At that time, we pulled over and the vehicle was towed to the service department at the local dealership. Just days before, the windshield wipers completely failed while driving, in the middle of a downpour. I had to pull the vehicle over and wait for the rain to calm before returning home. Also, the entire display panel went blank while driving, as if the vehicle was turned off. I was unable to determine speed etc. There had been a cascade of odd malfunctions days prior to the major events, the clock stopped working, the compass stopped working. The service department informed me that there was a "Bad Valve Body." I was told by the service manager that he had "never heard" of a vehicle doing this. My children and I are terrified to get back in the vehicle, as we almost had what could have been a fatal accident. I am in contact with GM/Chevrolet on possible remedies. I should note again that there are several other defects with the vehicle, that all seem to surround microchip/electrical components. They all seemed to have failed at once, which leads me to believe there is a larger systemic problem with this vehicle, the processors, and components. Again, this was a sudden cascade of failures. I have video of the windshield wipers non-functional during the rain. I was able to take the video after I had stopped. This is exceptionally dangerous. This vehicle is available for inspection. There were NO warnings lamps or messages. NO insurance has been involved. To my knowledge the dealer has not re-created the failures, but I have video of the panel black out as well.
