OBDII codes indicated the thermostat required replacement. Due to awkward location on this vehicle, I elected not to do it myself. also indicated front O2 sensor was failing. This is an easy replacement, but as it was going to the dealer, I had it done ny them. While in dealers another issue was diagnosed, and I authorized getting this taken care of too (can't remember details).
