1. After driving the car and turning it off, I get a loud bang coming from a gas tank. 2. Sometimes when making a hard right or left turn steering wheel vibrates, and the warning light for all wheel drive system comes on. When I turn the car off and restart it, it gs away. 3. After software installs due to recalls, when I accelerate my radio occasionally shuts off on its own, and then well come back on on its own. 4. After turning the car off when I restart it occasionally the clock in calendar revert to 00:00 for the time and the date resets to 1/1/20.
