Electronic throttle control (etc) warning light comes on speradictly. Still runs ok. The etc warning light did not come on for the dealership (so they claim). I had a coolant system leak and had to replace 2 thermostats, coolant housing and have the coolant system flushed and filled at dealership. Not covered under warranty. Not cheap. Picking up the car tomorrow.
