What 38 owners told NHTSA about the 2024 Chevrolet Blazer

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.

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.

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!

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.

Contining with issue referenced in 11701484. This morning (1/28/26) when leaving my home, I backed out of my driveway. Once I put the car into drive, the forward collision warning went off and locked up my car. The brakes would not release and I could not move out of the way of oncoming traffic. I do not know what allowed the brakes to finally release. I changed over to 4x4, put it into park and back to drive. My car finally was then allowed to move.

I have found multiple times that the Instrument Panel (IPC) display and the center Infotainment displays have gone dark while driving. This has put me in unsafe driving situations because I am unable to monitor my speed and other important information displayed on the dashboard, or to control critical safety controls such as headlights, and other ADAS safety controls. Several software updates have been installed by the dealership, but the problem has persisted, suggesting a hardware issue with the radio unit. The manufacture insist it is a software problem and that they are working on a solution. Declining to replace the radio under warranty, additionally, they want me to wait until a new update is released, and in the meantime, my bumper-to-bumper warranty is about to expire. I have found that the radio unit is the main control module for both displays, multiple ADAS controls, and Headlights, and it should be recalled, with the manufacturer extending the warranty or including the radio as a safety feature under the extended powertrain warranty.

To Whom It May Concern, I am submitting this complaint regarding my **2024 Chevrolet Blazer** and the handling of my case by GM, GM Financial, and affiliated dealerships. In **sub-zero temperatures**, the heating system in my vehicle completely failed while I was transporting my **newborn child**, creating a serious safety concern. I immediately sought assistance at **Moran Chevrolet**, where I was denied service, told no loaner vehicles were available, and advised to continue driving the vehicle despite the dangerous conditions. Out of necessity, I drove over **30 miles** to **Al Serra Chevrolet**, where my vehicle was finally taken in. I was provided a **gas-powered loaner** and was explicitly told that fuel expenses would be covered through **GM Executive Concierge**. Unfortunately, my experience with GM Concierge has been unacceptable. I was assigned a representative but have **never spoken to her live**, despite numerous calls and clear communication of my availability. I have spent **hours** attempting to obtain reimbursement and assistance, without resolution. My vehicle is now **back in the shop**, and this matter remains unresolved. Additionally, although I have paid my vehicle payment to remain current, I am requesting **reimbursement of this payment**. This expense was incurred as a direct result of GM’s failure to provide timely service, a comparable loaner, and effective concierge assistance during a documented safety-related vehicle failure. I paid under necessity to mitigate further harm, and reimbursement is appropriate to fully resolve this matter. I am requesting: • Reimbursement for fuel expenses related to the loaner vehicle • Reimbursement of the vehicle payment made under necessity • A written explanation for the concierge communication failures • Assurance that safety-related failures are handled promptly • Confirmation that this complaint has been escalated
