When owners complained
A spike years after the car went on sale usually means a part wearing

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

SERVICE BRAKES
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!

PARKING BRAKE
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.

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.

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.

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.
