Known Problems

The Check Engine Light may illuminate with stored codes P0133 and/or P0153. These may be "false" codes which can be corrected by reprogramming the powertrain control module (PCM) with upgraded software.

A squeak type noise may be noted from one or both front seats. Squeaks can be caused by contact between the seat track locating pins and the vehicle floor pan. Our technicians tell us the repair involves removing some of the seat locating pins.

The electric trunk release may not function correctly. Our technicians tell us an additional ground wire can be added which should correct this concern.
