Common Problems, Issues, Recalls, and Reliability

  • Failure of Front Turn Signal and DRL Bulbs

    The front turn signal and and daytime running light bulbs are prone to premature failure. Our technicians tell us that these bulbs can be very difficult to replace.

  • The Check Engine Light With Code: P0011, P0014, P0021, P0024, P0341, P0346, P0336, and/or P0391

    Vehicles with certain V6 engines may illuminate the Check Engine Light one or more of the following codes: P0011, P0014, P0021, P0024, P0341, P0346, P0336, or P0391. Our technicians tell us that some vehicles may require a powertrain control module (PCM) software update to correct this issue. Other vehicles may have excess camshaft end play on one or both cylinder heads which will need to be corrected using special procedures outlined by GM.

  • Check Engine Light Due to Loose or Worn Gas Cap

    A loose or worn gas cap could be cause the check engine light to illuminate.

  • Steering Wheel Position Sensor May Fail

    The steering wheel position sensor may fail, resulting in the service stability message being displayed.

  • Rear Axle Pinion Seal May Leak

    The rear axle pinion seal may leak causing fluid loss and possible internal rear end damage. Replacing the faulty seal will commonly correct this concern.

  • Contamination of extended life coolant

    Extended life coolant may become contaminated and require cooling system service before the recommended 100,000 miles.

  • Flush brake fluid every 60,000 miles

    Failure of brake components can be caused by contaminated brake fluid. To help prevent this the Brake fluid should be flushed at the very least every 60,000 miles.

  • Check Engine Light and Trouble Filling Gas Tank

    The 2005-2009 Cadillac STS may have issues with the EVAP system, a part of your emission control system.

    The EVAP canister vent valve or valve solenoid wiring may fail causing illumination of the check engine light , setting code P0446 , and problems filling the tank with fuel.

    To correct the issue, the EVAP canister vent valve , solenoid, and wiring must be inspected. The most common fix is replacement of the wiring connector or replacement of the vent valve assembly.
