We have to keep spare bulbs for all lights in the car at all times. We go through bulbs like water.
High mounted brake light never has worked. Dealer can't figure it out.
Brakes seized up one day. Somehow antifreeze ended up in the brake system and the dealer doesn't know how even though they handled ALL repairs and service on the car.
Power window motor on the rear door went out.
Throttle body hesitates. To replace is $1700.00
And last, but not least, tires keep experiencing slow leaks. We've purchased several sets, but no damage to the rims has been found and the leaks keep happening.
The car drives great. The hesitation started recently and isn't a major issue at this time. It's very comfortable to drive and ride in, but has too many little quirks that are just plain aggravating... and expensive.
I think you need to find yourself another dealer to service your vehicle. Obviously, they have no clue what they are doing.
