We have had to deal with severe overheating issues and failing parts our entire ownership of this vehicle, both of which then cause other parts to fail, as the parts are so poorly made and heat sensitive. We have replaced the turbocharger (twice), intake manifold + valve cover (twice), catalytic converter, the radiator (THREE TIMES), the cooling fan (twice), the MAF sensor (twice), and much more. All of this has been done over the course of 18months. This has easily been the most expensive car we have ever owned due to the constant repairs, all of which has been because of Failing Parts and overheating.

First problem started when radio remained on after key removed from ignition. Radio would turn on and off when car was off and drained newly replaced battery. Advised to remove fuse as temporary fix. Car was also losing power when highway driving (up to 70 MPH). I don't speed, but car struggled to go above 70 MPH. Thought I smelled something burning, had radiator checked, oil changed, fluids added at beginning of october. Three weeks later on city street, slowing for traffic when car lost power. When traffic started moving, car continued to slow to complete stop in the street despite stepping on gas. Waited 25 minutes for tow, but when tow driver came, car was able to start and move. Less than an hour later, the problem happened again and car was towed. At mechanic, computer codes indicated low/no transmission fluid (even though fluid was added at oil change only three weeks prior). No evidence of leaks. Mechanic added fluid and went for ride on suburban back road, car lost power after 10 minutes. He had to wait approx 20 minutes for car to move again. He drained transmission fluid and found metallic bits, and says transmission would likely need replacing. Car has fairly low mileage '54k miles' and has been properly maintained. Also car was previously serviced because key was stuck in ignition.

Radio is not working. Therefore, I am unable to hear any alarms (door, blinker). I am also unable to use hand free calling or on star. Also, the car will randomly attempt to start if the key is left in the ignition.

Checked car while stationed, when running always needs more cooling maybe electrical burnout of a part that connects to the radiator fan. When put the diagnose code, none is given, and temperature goes up to 225, its a hazard if a person does not know that fan is not working, putting refrigerant all the time. Read that there is a new re-design cooling fan assembly.
