2024 Chevrolet Blazer Complaints

Sudden catastrophic drive train failure while driving. Car stopped instantly and was totally immobilized. It had to be dragged onto a flatbed tow truck. It is at dealership now for evaluation.

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.

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...
