Q: Radio or other electronic bits act weird

asked by on

My 2011 Volkswagen Jetta is still pretty new, with approximately 22,000 miles on it. I like the car and it does what I need, but it has a lot of quirks that make me worry about the electronics. The radio will randomly blip off or a light will illuminate on the dashboard. The Check Engine light has been coming on and turning back off a lot lately. At what point should I have it checked out? I don’t want to show up with a car that doesn’t have any lights illuminating on the dashboard and is running fine.
