I had no warning or indication whatsoever that my battery was going bad. I was at a major red light and my car shut down, then started back on its on with the entire panel lite up. The light changed and when I tried to turn I had hardly any stirring and almost no brakes. I almost ran into the car in front of me. I was able to get it into a parking spot and then it still gave me no light or notice of a battery issue. Because it had a recall on it that was repaired four days prior I had it towed to the dealership. They told me it was the battery but even when I picked up the car (for AAA to install the battery), it still showed 13.6% power on a 14 volt battery. This issue almost caused me to have an accident and caused me to waste $168 for a tow.

I have received this warning a few different times “Steering Assist is Reduced". Which causes my vehicle to not blow cold air when AC is on. Fans are louder than normal. And when I turn off my vehicle fans continue to run for roughly around 8 minutes.

My Drive Assist stopped working. Then my Air conditioning stopped blowing cold. Then the temperature gauge stopped working. Upon turning the car off the fan continued to run for several minutes. Took to repair shop where it required a new thermostat housing, coolant temp sensor and coolant flush. The total cost for repair was $1,131.52. The car has 37,000 miles on it. Barely out of warranty. This is a well-known issue among Chevy owners.

When shutting off the car, the fan continued to run. I started the car up again to see if this would allow the fan to turn off. No luck. The steering assist was dis-enabled on the dash. I took my car to the dealer to find out that it has a bad thermostat and that my radiator was leaking. The thermostat was covered but I had to use my extended warranty to pay the additional repair. My deductible for my extended warranty is $300.00. My daughter has a 2021 Chevy Blazer and the same situation happened. There was a recall and all her parts were covered.
