2010 sonata service light is on

Craig Sherman

Asked by Mar 13, 2016 at 08:16 AM about the 2010 Hyundai Sonata Limited

Question type: Maintenance & Repair

My service engine soon light is coming on and off.  Hyundai said most likely
the gas cap.  My car is still under the warranty plus added 6 year bumper
to bumper warranty.

Any ideas on how to stop this light from keep coming on?

Hyundai is just guessing it can be the gas cap. You have to scan for the codes. Any sensor on your car can be detecting a problem. Your local auto part store can scan the car for free. Post the 4 digit codes back here and we'll help figure out what to do next. Once you fix the problem, the light will go out.
