Warnings would appear on the dash that different functions were not working and to visit the dealer, then they would go away, then reappear again, over and over. Technicians and the Service Writer at Stephen Wade were excellent. The appearing and then reappearing of these warnings was perplexing. That the Service Department could find the cause of these warnings goes beyond service. They determined that a previous enactment was the cause, nothing to do with the manufacture of the Rav4. Brilliant! Permanently repaired. Thank you service department techs at Stephen Wade Toyota.
