Fuel pump and crankshaft sensor both went out on vehicle at same time. Repair of crankshaft sensor was a $400 and fuel pump repair was $740. Doors do not lock properly when using the key remote and lights inside the vehicle on controls flicker on and off. Heating element in leather seat on passenger side has never worked and had to replace tires due to unusual wear and tear. Cost to replace tires was $478. Driver sides door will not shut all the way due to alignment problems and this problem has not been corrected. Had to replace fuel filter due to leaking and this cost $178. Car has become a money pit and it only has 77,000 miles on it.
