Warnings problems of the 2023 Chevrolet Tahoe

To NHTSA, I am reporting a serious safety defect in my 2023 Chevrolet Tahoe purchased from criswell Chevrolet (gaithersburg, MD). Defects include a documented brake system failure while driving and repeated electrical/shift faults preventing shifting out of park. The issue is ongoing even after the dealer/manufacturer stated it was fixed. Key events: Feb 3, ~12:45 while traveling ~35–39 mph on a five?lane road, brakes failed. I slowed by coasting uphill and using maximum pedal force to ~5–7 mph before stopping. I have video of the incident and two other times this has happened with pictures as the car was in park. Three prior start-up incidents: all dash lights illuminated (including brake failure and forward collison system unavailable); vehicle stuck in park. First required towing; dealer could not replicate despite reported stored codes. Subsequent event stranded my family. I have notified Chevrolet and the dealer; their offer does not address safety or recurrence. Please record this complaint, assess broader risk, and advise on related recalls/investigations. If there is a path forward to ensure the safety of my family, please respond with that guidance. My phone number is [xxx] . Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Vehicle was around empty with 40miles remaining and would not start via keyless remote. Upon starting the vehicle all lights on the dashboard came on, this has happened previously and it fixed itself. When this happens, I have 0 brakes. Forward collision unavailable, service brake pads monitor, service traction control, service steering column, but most importantly brake system failure.

While driving to my appointments via the freeway, all of a sudden the vehicle slowed down, I noticed most of the warning lights were on including the check engine light that was blinking. I happened to be near a GMC dealership which previously did repair work on my vehicle and left it with their service center for a diagnostic inspection. A week later my service advisor contacted me with their vehicle condition report that my vehicle had camshaft and internal engine group issues. He quoted repairs but recommended replacing the engine. Repair or engine replacement $21,296. 51. Six months before this issue I had the same issue the warning lights and it resorted in replacing the brake control cylinder. Once repaired no issues/messages or symptoms with my vehicle until this current engine problem/replacement.

First the front collision warning systems kept coming on and off. Then the engine died on the highway and I had to restart. I drove a little further and it died again and would not restart. I had it towed to the dealer and they are telling me the engine has seized and needs to be replaced. I have 40,000 mile and the car is 2 years old. It was very dangerous to have the car die twice while at speed on the highway.

Vehicle 1 pulled out into vehicle 2s lane and cut them off causing vehicle 2 to slam on the breaks causing my vehicle ( vehicle 3 ) to collide into the back of vehicle 2. No emergency breaking a-curd and no airbags deployed durring contact at rate of speed of 45-60mph. Total damage to vehicle 2 rear end and total damage to vehicle 3 front end.

The infotainment screed goes black. To get it to go on you have to turn the car off, get out of the car with the key fob so the vehicle is completely disconnected and wait 10 to 15 minutes. After it starts working the infotainment systems "crashes" in about 30 to 45 minutes. It is a constant problem. The infotainment system includes all vehicle safety systems settings and speaker. The warnings will not work because the speaker is not working. Also the on star system will not work in case of an emergency. On star uses the infotainment system to work. I can not stop all the time so it dangerous while driving. I took it to the dealer and they said gm knows about the problem but does not have a fix. The problem started near the end of June, 2024. The issue was reproduced by the dealer.
