As a simple, no cost option... disconnect the negative ( black ) battery terminal from the 12v battery and wait 15 minutes. Then reattach. This will reset the car computer control memory, and the car should go back to inital factory settings.

It may not "fix" your problem, but it for sure can't hurt.
It's a cheaper and quicker way to find out before going to a dealer.
The dealer will probably try that also!
