The oil in the engine constantly sludges even with regular maintenance with full synthetic oil, I went over a pot hole and two of the rear lights went out and won't go back on even after replacing bulbs and wiring harness, and the worst of all is the suspension, the lower control arm and the trailing arm both have gone out after only 20k miles of light mostly highway driving, this car offers nothing but problems it's no surprise that they discontinued the model it's an absolute nightmare. I bought it brand new and it feels like I'm going to die in it, every speed bump or pot hole I go over feels and sounds like I'm hitting a wall, I've replaced the ball joints and am thinking about replacing the control arms because I'm worried they are going to break. …
