At first, and only on cold/rainy/snowy weather, while driving the radio would randomly turn off and turn itself back on (i have videos of this). Sometimes it would last a few seconds, sometimes a few minutes. While this was happening, the blinker sounds wouldn't work. I brought it to Chevy in Geneva, NY for diagnostics. No check engine codes ever. They told me that the radio computer needed to be updated. I had them fix it, only to find out that the problem would still happen. Over a few months, it developed more symptoms. It started to not shut off when I pushed the button, and it also started stalling when it went into auto off, but would turn back on if I put it in park and re started. At first it would stall in auto off at random times. This caused an accident in the summer of 2019. I was at a stop sign, waiting to make a right hand turn, took my foot off the brake and car stalled. The car behind me thought I was going and rear ended me. I had to drive around in the summer with the heat on, as it was the only way to prevent the car from going into auto off. I had the car looked at a few more times after that (paying $100 diagnostic fees every time). Brought it back to chevy and the told me it was because of the damage to my trunk allowing water to get to the battery (it wasn't). Issues then turned into stalling at auto off, but not turning back on once in park. I brought it to the dealership I bought it from and they looked at the alternator and had them clean all batter
