What owners wrote
The light that comes on when you open the passenger door (under the dash) stayed on with the door shut. The light bulb, burned the plastc around the wires and started the carpet on fire under the dashboard. My husband removed the light bulb and burned his fingers to put the glowing carpet out. Then, my turn signals worked sometimes and then at other times did not. They eventually stopped working all together. I took the car for repairs and was told that a relay switch had gone out.
While on a trip, I left car sit for 1 week (approximately 7 days) in the garage of my house with no accessories plugged in, and the car would not start when I returned. The battery was completely drained and did not even have enough power left in it to even unlock the doors. Took car to dealership and they found nothing wrong with the battery, charging system, or current draw when not running. This sort of thing should not happen to a car with an msrp of $30,000.
