2017 Traverse
 

I have a 17 Traverse that seems to be bipolar. For the last few months when I get gas as soon as I take off the gas cap it runs so rough until the cap is back on. If I turn the car off to get gas it doesn't start for 10 mins or more. A few days ago while driving the radio volume cranked up by itself repeatedly then later turned off and wouldn't come back on. Then every dash light came on, gauges all stopped working once I got home still no change but once I shut it off the blower was still on, side detection lights on drivers mirror still on but car will not start again!! Have tried for days and still won't start and side detection light is still on. This car is 4 years old and such a pos. Anyone else having the same issues ?
