In past 6 weeks, and in 5 repair visits at dealer:
Internal short in coils 2 and 3 cylinders and ignition coil replaced.
Internal short in low fuel pressure sender, and it was replaced after the car broke down and had to be towed (Roadside Assistance thought it was OK to leave me in a dangerous crime area for 2 hours, despite telling me the truck was 20 minutes away).
Exhaust valves replaced, and fuel injectors replaced.
With these engine problems, the car is unreliable.
We had the same problems. It went from the coils to a blown head gasket. STILL dealing with.
