Known Problems

On some models the powertrain control module (PCM) software delays idle speed changes during cold starts causing stalling problems. A software update is available to repair this issue.

Certain models can get a brake squeal at the end of a stop due to the front brake pads leaving a film on the brake rotors. Replacing the brake pads and turning the rotors will fix this issue.

On some models the rear wire harness for the Anti-lock brake system (ABS) can fatigue and break causing the ABS light to come on. Replacing the harness with a new updated harness should repair this problem.

The automatic transmission accumulator cover can leak due to a failed o-ring. Replacing the o-ring and cover will commonly correct this issue.

A worn vehicle speed sensor driven gear can cause the speedometer not to work. Replacing the worn out speed sensor should correct this concern.

There is an issue where the transmission can have a torque converter problem, or the computer monitoring the torque converter can misinterpret the information, and in either case this can cause the Check Engine Light (MIL) to illuminate. The problem will need to be diagnosed and depending upon what is causing the issue, the transmission will have to be repaired or the computer replaced.

A Loose or worn gas cap may cause Check Engine Light to illuminate.

This vehicle is known to set false trouble codes, which causes the Check Engine Light to illuminate. To resolve the problem, the PCM needs to be re-flashed, which is covered under the vehicle's emission warranty.

A ticking noise may be noted from the engine valve train area. This is commonly caused by varnish build up in the hydraulic lash adjusters (HLA). Our technicians tell us that using Mobil 1 synthetic oil has been successful in cleaning the varnish deposits and quieting the lifter noise.

The transmission may develop a harsh shift condition with the Check Engine Light on and fault code P0717 stored. This is commonly cased by a failed input speed sensor (ISS), located inside the transmission. The wiring at the sensor may be found damaged. If so, the sharp edges near with ISS wiring should be filed smooth to protect the new speed sensor wiring from damage.

The ignition switch may fail resulting in a no start condition. Replacement of the failed switch is necessary to correct this condition.
