I bought a 2015 Rav 4 with 38,000 miles on it a few months ago. I have been very pleased. Until yesterday. The check engine light and the AWD light came on at the same time. I have searched threads all over the place and saw that it could be as simple as a loose gas cap. I tightened it, no luck. I bought the Rav from a small dealer but called the initial dealer and they reported that the extended warranty came with the car and not the dealer so that is in tact. Any suggestions?
