Verbatim from NHTSA complaints, newest first
“Reviving the p2138 code for throttle/accelerator sensor. Still getting code after replacing 3 accelerator peddles. Possible manufacture issue with wiring that water gets into connectors shorting out that system”
“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.”

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.

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.
