I have a 2015 Q3, and went to a self serve car wash today. No problems at all prior to car wash, but the car would not start after the wash. The ESC light, engine light and battery light all came on. We weren't sure what was wrong, but tried jumping the battery and that was it...it started and has been fine. Any ideas why a car wash would cause a dead battery? I really don't want this to happen again! Thanks!

Batteries can go quickly. Once they drop below a certain threshold, the electronics won't attempt a start. I had batteries go in both of our vehicles last year with very little warning. My wife drove her Passat to a restaurant, and it would not start when she tried to leave. The heat here in Houston is hard on batteries.
