2024 Chevrolet Blazer Complaints

SERVICE BRAKES — Filed 07/01/2026

While driving my 2024 Chevrolet Blazer EV, the vehicle suffered a sudden, complete failure of the power braking assist system. The failure was accompanied by a rapid cascade of three sequential dashboard warning messages in immediate succession: First Warning: "Service ESC" illuminated alongside the "Brake Park" warning light. Second Warning: "Brake Assist Failure. Press Hard to Brake. Speed Limited" illuminated with "Brake Park" remaining on. Third Warning: "Brake System Failure. 62 MPH Top Speed" illuminated with "Brake Park" remaining on. Immediately upon these warnings triggering, the power braking assist and emergency mechanical reserve failed completely. When pressing the brake pedal, the vehicle did not slow down, and the pedal failed to engage the brakes. To avoid a catastrophic intersection collision and bring the vehicle to a halt, I was forced to deliberately steer the vehicle into a concrete curb to use friction to stop the car. The vehicle is a total loss of braking safety and cannot be driven. Safety Risk: The sudden loss of braking assist creates an immediate crash hazard, as stopping distances are severely multiplied. Limiting a vehicle to a maximum speed of 62 mph while experiencing zero brake assist on active roadways places the driver and surrounding traffic in extreme danger.

ELECTRICAL SYSTEM — Filed 03/21/2026

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.

UNKNOWN OR OTHER,FORWARD COLLISION AVOIDANCE — Filed 08/01/2025

The front camera lens cover — located in the grille below the Chevy bowtie logo — has developed a spiderwebbed/shattered crack pattern. There is no impact damage to the surrounding grille or bodywork. The vehicle was garaged and not in use when the damage was discovered. The camera appears to still be working and parts of the image are crystal clear but the cracks in the cover distort the picture and make it impossible to use reliably. This is consistent with a material defect, not road damage. I have opened a case with GM Customer Care regarding this defect. My case number is: XXX. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I fear this will leave me stranded and my only course of action will be to rip the door off in anger. Many others are experiencing this issue. Chevy needs to address this.

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!
