Common Problems, Issues, Recalls, and Reliability

  • Steering Wheel Position Sensor May Fail

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

  • Check Engine Light Due to Gas Cap Issue

    Illumination of the check engine light may be the result of a loose or worn gas cap .

  • Front and Rear Light Bulbs may Fail

    The front and rear light bulbs are prone to premature failure. Our technicians tell us that the front bulbs can be very difficult to replace.

  • Reduced Power and Check Engine Light

    The throttle position sensor (TPS) on the Cadillac CTS-V is notorious for failure which causes:

    • Check engine light
    • Reduced Power message
    • OBD trouble code P2135

    This issue is related to the throttle position sensor, and can be caused by faulty wiring to the TPS, bad connection at the TPS, or a failed TPS.

    To correct this issue, the wiring harness, connector, and throttle position sensor must be inspected, tested, and/or replaced. The most common cause is a faulty TPS.

  • 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.

  • Contamination of extended life coolant

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

  • Check Engine Light Due to Gas Cap Issue

    A loose or worn gas cap may cause check engine light to illuminate.

  • 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

    Brake fluid can become dirty and may cause problems with the hydraulic system parts in the brake system . We recommend flushing the fluid at least every 60,000 miles.

  • Stalling or Low Engine Idle Speed Due to Dirty Throttle Body

    A dirty throttle body may cause a lower than normal idle and possible stalling condition. Performing a throttle body service will commonly correct this concern.

  • 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 Due to Restricted Secondary Air Injection Check Valves

    One or both secondary air injection check valves may become restricted causing poor air flow resulting in illumination of the Check Engine Light . It is often recommend to replace both check valves even if a fault code is set for only one bank of cylinders. Replacing only one valve may result in a return trip to the repair shop.

  • Replace spark plugs every 100,000 miles

    The spark plugs should be replaced every 100,000 miles. Our technicians recommend replacing the spark plug wires also at this time
