i pulled on to the road and i heard a loud knocking and my vehicle started skipping and wouldn't go. the lights on the dash lit up and said, "brake failure" and "emergency brake failure" and i had no brakes. I managed to coast into a parking lot. The engine light was on. I turned the vehicle off and waited about 5 minutes and turned it back on, The engine light remained. The first time this happened I was going down the road and the vehicle started sputtering, the emergency brake light came on the dash and the car shut off. It has a rough idle when you start it. I am terrified of this car. I have grandbabies in the car with me, Had i been on the highway either time i would have caused a terrible accident. The dealer says they can't get the car to do it so they can't fix anything. It has happened twice so you know it will again.
The check engine light came on at 14k miles indicating there was an emissions error. The brakes squeal and have had to be replaced 3 times since the original purchase in March of 2024. After the third replacement of brakes they still squeal. Even if the car is not braking it makes the noise. The radio shuts on and off constantly. Chevy reported they are aware of the issue but there is no fix at this time. The dealerships reset the radio but the issue persists. I've had to park the car because I'm afraid the brake issue is much more than they're willing to admit.

I was driving south on Highway 395 with 2 of my friends on our way home from vacation, which is a 2 lane road in the mountains. About 45 miles north of Victorville, CA. As I was accelerating, my vehicle all of a sudden dropped adaptive cruise control, the engine light started blinking, traction control errored, and I got a service ESC message on the dash. I let off the gas a little and everything seemed fine but when I reapplied pressure to the gas pedal the engine started making a loud ticking sound and had barely any propulsion. I had to keep going and was luckily able to find a safe place to pull off the road (which had many blind curves and minimal shoulder space along the highway). Had there not been a safe place to pull over before the engine completely died we could have been hit by any of the many semi trucks traveling on that road. …
