| 39060 mi | Defective turbo chargers |
| 41540 mi | after replacing turbochargers there was an airlock in the cooling system that wasn't noticed till the heating season. The car would blow cold air at an idle but heat normally when driving along. Cooling system had air lock in it causing the passenger compartment heater to blow cold air at a stop but blow warm air once moving again. |
| 66000 mi US $1200 |
Gas odor rear of car. Gasket around one of two fuel pumps leaking small but evident amount of fuel. Both pumps replaced as labor was dominant cost to repair and the same whether one or both were replaced. Pumps had to be replaced as gaskets etc are one unit! If I did not love the car I would be very upset! |

#5 fuel injector stuck open, CEL and lots of white smoke out of the tailpipe, smelled strongly of gas. |
| 129900 mi | after replacing #5 fuel injector, could smell gas under the hood after driving the car, especially if driven spiritedly. Fuel rail replaced. #4 fuel injector stuck open, shortly after the #5 fuel injector failed stuck open. The stop was originally going to eat the cost o the fuel rail, ate the cost of the second injector instead. |
