Open the full vehicle complaint log (all categories)On March 21, 2026, I rented a Chevrolet Tahoe (approx. 24,450 mileage driven). While operating the vehicle on a freeway at approximately 40–50 mph, the braking system and ABS failed suddenly without any warning. Barely no brakes were able to apply to stop the vehicle. It also started to show that ECS service (Electronic Stability Control) and Service Brake Pad Monitor. Many faults started to show.
While I was driving, my vehicle suddenly lost all power I encountered a misfire with the engine light flashing, and diagnostic codes P0353 and P0300 indicated a misfire on cylinder three. The coil pack and spark plugs for that cylinder were replaced, yet issues persist and problems continue. There is a strange popping and cracking noise coming from my dash. My brakes are also making it loud sound randomly when pressing on breaks yet brake pads are fine
My 2025 Chevrolet Tahoe Z71 3.0L LZO Duramax with approx. 3,380 miles experienced a sudden and complete engine failure while towing my camper on the interstate at night, in the rain, while traveling alone 375 miles from home. The vehicle lost power, displayed warnings, and became inoperable, forcing me onto the shoulder in unsafe conditions. The engine has been diagnosed as requiring full replacement due to a defective crank end play / thrust bearing, under Technical Service Bulletin (TSB) 25-NA-307. This is a significant safety concern for a new vehicle and could have caused a crash. GM has multiple documented issues with this model year, and the car has also experienced unresolved infotainment defects, as outlined in TSB #PIT6393F. Requesting NHTSA to investigate a potential safety defect.
After my vehicle experienced a brake system failure 3 weeks ago and I got my vehicle back from the dealership. I noticed that my vehicle has no emergency brake so in the event of this failure and/or future brake system failures there was no way to stop my vehicle. Their emergency brake is technically a parking brake that can only be applied when the vehicle is completely stopped. I'm not sure how a vehicle this unsafe would be even legally sold or allowed to operate on the roads.
I was driving and the driver dash frozen. I couldn't tell my speed, it didn't indicate blinker or hazards. It would say i was in "D" when the car was parked. The center dash shut down completely. The seat belt indicator didn't work, none of the charging ports worked. **THIS IS A RENTAL CAR**** I do have video of the dash.
