I bought a 2019 Chevy Impala Premier with 45,000 miles. It's been garage kept since April, I've driven it about 10 times due to owning a Wrangler and it's summer! But I noticed the passenger mirror driver assist light would flash on and off inconsistently and sometimes it would stay on for no reason and then it wouldn't work (not showing a car when there was one). I took it to the dealer I bought it from who took it to their sister Chevy dealer and said there was nothing wrong with it.

It has been throwing the driver assist off on its own. I knew it wasn't throwing a code. I took it closer to home and the Chevy dealer told me today they've never seen this and not sure what's going to happen. I hope warranty covers this. I plan on using this to commute to work (I'm an educator) and will be driving interstate. While I use my mirrors responsibly, this car has a lot of BLIND SPOTS, but I am short too so that could be a problem.

This car is fun to drive and have had no other problems with it (hope I won't after this).
