Since buying the car in 2024 I have experienced multiple incidents where the system hard brakes for no reason, including times while driving. The emergency recall on this vehicle was repaired last year and since that repair this issue has occurred 2 more times, once earlier in 2026 and then most recently as yesterday despite claims by GM the issue has been fixed. My daughter currently drives this vehicle and is afraid she is going to get into an accident because of this issue. I tried to initiate a buyback but due to the miles on the vehicle GM would only settle for 4k.

The car just stopped while I was driving. I was in an intersection. The car would not turn back on

"While attempting to merge onto a high-speed freeway on-ramp, the vehicle suffered a sudden and catastrophic loss of engine power, rendering it unable to accelerate and creating an immediate life-threatening safety hazard. The vehicle was restarte and driven home, where an onboard diagnostic check revealed an emissions system failure. The dealership later confirmed that BOTH close-coupled catalytic converters on the 3.6L V6 were damaged. The check engine light was a solid light. Not flashing.

Vehicle: 2024 Chevrolet Blazer VIN: [XXX] Component: Engine Cooling System (Radiator) Description of Incident: On XXX the vehicle was brought in for a routine maintenance service at approximately 20,000 miles. During the inspection, technicians at Hamilton Chevrolet in Warren, Michigan discovered a premature radiator leak. The servicing technician noted that this is a common failure on modern Blazers due to a manufacturing material mismatch, specifically where the plastic end tanks meet the aluminum radiator core. This structural component failure poses a severe safety risk. A rapid loss of engine coolant can cause immediate engine overheating, thermal management failure, and a sudden loss of vehicle propulsion while driving at highway speeds, significantly increasing the risk of a crash. Corrective Action: The defect was located and the radiator was subsequently replaced under the factory warranty by Hamilton Chevrolet (Warren, MI). However, this failure occurred far too early in the vehicle's lifecycle, indicating a structural or material defect in the OEM radiator seams. Please investigate this issue, as premature cooling system failures on this model year present an ongoing safety hazard.

Driver Information Centre (DIC) and Infotainment go dark. This has happened twice now over the last 2 months. While driving suddenly the infotainment goes blank and loses the radio and then the DIC follows by going blank (dark). So I was left with no speed indication. The car drives normally during that time. After 30 seconds to a minute the screens come back on as if it rebooted while driving.

On February 4, 2026, my wife drove to the bank, a trip of about 10 to 15 minutes, and turned off the car at the ATM. When she tried to leave, the vehicle wouldn't start. After a while, she opened and closed the door and locked and unlocked the car twice with the remote control, and the vehicle started and she was able to drive, but all the warning lights on the dashboard remained on. It is currently at a Chevrolet dealership for diagnosis.

On 10/29/25 I brought the vehicle in to Richard Lucas Chevrolet due to the alert from my insurance co that there was a recall with parking brake system. The dealership checked the car and told me they had to order the part that was needed due to the recall. Prior I also made the dealer aware that the car had recently stalled on me in the middle of the street, I was told by the dealership that this was apart of the recall! The dealership allowed me to drive the car and stated to me that they would call me when the part comes in! 2 days later on 11/1/25 while driving the car lost control, the brakes wouldn't stop and I crashed into 2 parked cars and landed on top of the second parked car which was a pickup truck! All of the airbags deployed and my body is pretty messed up from this horrific crash and this has caused fear in me of driving!

The car due to the parking brake system recall lost control, the brakes would not stop and caused the vehicle to crash into 2 parked cars, landing on top of the 2nd vehicle which was a pick up truck

My 2024 Chevrolet Blazer EV AWD has experienced two separate incidents involving sudden loss of propulsion without warning. First Incident – XXX While driving in [XXX], the vehicle suddenly lost propulsion without warning while I was in a turn lane in front of a medical center. Following the loss of propulsion, the Driver Information Center displayed warnings associated with the AWD system, shift system, and high-voltage system. The vehicle could not be driven or shifted and became disabled in the roadway, creating a potentially hazardous traffic situation. An expedited tow was required because of the location of the disabled vehicle. The vehicle was taken to a Chevrolet dealership in Novi, Michigan. I picked it up on XXX. I was informed that a vehicle-wide reprogramming had been performed, the vehicle had been updated with the latest available software, and the condition should be resolved. Second Incident –XXX Only 12 days after the vehicle was returned following the reprogramming, the vehicle experienced another sudden loss of propulsion without warning while my cousin was driving on [XXX]. Following this event, warnings were displayed indicating that the AWD system, Electronic Stability Control (ESC), traction-control system, and high-voltage system required service. During this incident, the vehicle could be shifted into Neutral. Good Samaritans pushed the disabled vehicle from the roadway into a nearby parking lot. OnStar was contacted, and the vehicle was towed back to the same Chevrolet dealership that had serviced the vehicle following the XXX incident. The vehicle has therefore experienced two sudden losses of propulsion within approximately two weeks, with the second event occurring only 12 days after a vehicle-wide software reprogramming intended to address the first event.
