ON MONDAY, 6/15/26, WITH APPROX 45,400 MILES, I WAS DRIVING DOWN THE ROAD AND TRUCK SAID SERVICE TRANSMISSION. THE GEARS WOULD SHIFT, BUT IT LAGGED A LITTLE BIT. I SCHEDULED AN APPT FOR TWO DAYS LATER, AND ONLY DROVE IT WHEN I ABSOLUTELY HAD TO, WHICH WAS ONLY TWICE BEFORE MY SCHEDULED APPT. I GET IN IT TO DRIVE AND IT SAYS SERVICE TRANSMISSION- UNABLE TO SHIFT SOON, THEN ON MY WAY TO THE DEALERSHIP, IT SAYS ALL OF THAT, PLUS SERVICE DRIVER ASSIST SYSTEM. CHAVY'S QUALITY ASSURANCE TEAM NEEDS TO GET IT TOGETHER! THIS IS ABSOLUTELY RIDICULOUS.

Engine failed and no light or warning besides check oil was shown on truck. The electrical system also went out (a year before engine failure) so car wouldn’t start.

Was driving east on i40 between Hinton and calumet when my truck through a check engine light and service parking break. I pulled over it smelt like burning wires I cleared the codes with a code reader and turn the truck on the accessory when smoke filled the cab I got out and the truck was in flames.

I was travelling on the highway at approximately 72 miles an hour in the left lane trying to pass a vehicle in the right lane. while accelerating my truck was like the brakes were slammed on and all kinds of lights starting flashing. This included the check engine light, low oil pressure light and lane assist lights. The truck shifted into Neutral and I could not place back into drive. I swerved and almost lost control of the vehicle and nearly missed colliding with the safety rails on the left of the road and then with the car on the right side. I then pulled onto the shoulder after nearly being rear ended by another vehicle approaching on the left. The vehicle would not react to the gas pedal. I pulled onto the shoulder and turned the vehicle off. Tried to restart but again nothing but mutliple lights and warnings. I checked my app for Chevrolet and it stated that the vehicle needed engine and transmission system service. Variable valve timing system needs serviced. Ingition system needed serviced. The onstar diagnostic alert indicated P0016 was detected. I opened the hood to inspect and the coolant overflow was spewing coolant. I checked the oil level at that point and it was just a little below full. I had taken this vehicle into the dealership two other times stating that the vehicle had stalled before on the highway but not to this degree. The other two times it stalled when accelerating it would allow me to pull over and restart. But both of those times I never had any flashing lights or diagnostic codes. I explained this to the dealership and how unsafe it was. Both of those times almost ended in a vehicle accident with other vehicles around me. The dealership said they could not diagnose any issues unless the truck created a diagnostic code. These issues have been ongoing with these vehicles for a long time and the dealership just did not want to deal with them. I had the vehicle go thru the recall diagnostic tests. It did not fix them

While driving, the vehicle suddenly displayed “Service ESC” and “Service Traction Control” warnings. Shortly after, the engine stalled and the vehicle became difficult to restart. Vehicle experienced rough running/misfires and loss of power. Diagnostic trouble codes retrieved included P0300, P0106, P3498, P00FF, and U1962. The issue appears intermittent but creates a serious safety concern due to unexpected stalling while driving. Concerned about possible electrical, engine management, or stability control system failure affecting safe operation of the vehicle. No prior warning before incident.
