Engine temp gauge stops working causing the air to stop working and the cooling fan to rev to highest rpm. Also a warning that the steering assist is reduced.

I was driving into a parking lot when my back passenger side window imploded like a rock was thrown at it, but no rock and nobody in sight. I looked all around for a cause but believe it somehow spontaneous shattered. Thankfully 3 minutes prior I had dropped my kids at school otherwise there would have been injury I am sure.

2019 CHEVROLET BLAZER

Electronically controlled thermostat and sensor fail or get stuck at a much lower coolant temperature causing the dash to display the “steering assist is reduced drive with care.” It isn’t just a message, the steering is much harder to use potentially causing an accident. The ac completely doesn’t work causing potential for sensitive, elderly, or young children and pets to overheat inside, it’s significant risk of injury or death from the hot summer temperatures. The engine coolant temperature…

2025 CHEVROLET BLAZER
Filed May 22, 2026
Just purchased a used 2025 RS EV on 5/2/2026. When I got home I found out the Google maps and on star app wasn't working. Called on star and they can't connect to the car and that the telematics module is probably bad. Checked my Chevrolet app and it reports that it hasn't connected to the car for over 6 months. Now waiting for replacement part going 3 weeks now. A little pissed off that dealer did find before they sold me the car.
