When owners complained
A spike years after the car went on sale usually means a part wearing
out on schedule across the whole fleet — the kind of pattern no single
owner can see from inside their own car.

NHTSA investigations into the 2024 Chevrolet Blazer
An investigation is the step before a recall: the agency has seen enough
complaints to look into a pattern itself. An open one means it thinks
something may be wrong and nothing has been fixed yet.

Electronic Brake Module Component Failure
On April 11, 2024, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE24011 after receiving complaints concerning a loss of brake assist in 2023 MY Cadillac Lyriq vehicles. These complaints allege a hard brake pedal, followed by a “Brake System Failure” message at start up or while driving. GM shared records regarding several internal investigations for loss of brake assist due to alleged spindle fractures in the eBoost system. GM has stated that in the event of a spindle fracture, anti-lock brakes (ABS), stability control, and traction control remain functional until th...
Recalls on the 2024 Chevrolet Blazer
A complaint is one owner's allegation. A recall is the point at which
the manufacturer or a regulator agreed the defect is real and dangerous
enough to fix for free — however old the car is.

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.

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 radiator had a crack that nobody located even though I had been smelling antifreeze since I purchased it at 24,000 miles just over a year ago. I brought it in for an oil change today because I was leaving town for the weekend tomorrow and now a hole had blown through the bottom of the radiator. Had this happened when I was in a remote area of the mountains without cell service this could have been a very big problem. Or had it blown while traveling up the mountain pass it would have put my life and others passing me on the road at risk. There weren't any warning lights on and the car never overheated. There weren't any outward leaks up until the hole was blown in the radiator. I have had it in several times for oil changes and there were never any visible leaks noted. Luckily my engine never blew because I've been driving with a cracked radiator for at least a year now.

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.

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.

I am filing a complaint regarding my 2024 Chevrolet Blazer EV (VIN: [XXX] ) due to an unresolved defect and repeated unsuccessful repair attempts. My vehicle has been presented to the dealership on four separate occasions for the same recurring mechanical noise issue. Despite these repair attempts, the defect has not been corrected. In total, the vehicle has been out of service for approximately thirty cumulative days. After the most recent repair, the same issue has again returned. I now have video documentation of the recurring defect. Additionally, during one of the repair visits, I was provided a gas-powered rental vehicle and incurred out-of-pocket fuel expenses, despite owning an electric vehicle. General Motors has declined to offer reimbursement for these expenses. Due to repeated unsuccessful repair attempts and the amount of time the vehicle has been out of service, I have formally placed General Motors on notice under Michigan’s Lemon Law and am pursuing review for repurchase or replacement eligibility. I am requesting assistance from the Attorney General’s office in obtaining a fair resolution, including reimbursement for expenses incurred and proper resolution of the ongoing defect.
