RepairPal Certified shops can diagnose and repair your 2012 Toyota RAV4. They provide transparent pricing with a minimum 12-month or 12,000-mile warranty on repairs and services.
We could throw out some idea but scanning why the check engine light is on is going to your best route. Report back with the codes and we can dive a little deeper. If you need to find a shop near by check out this link.
