Known Problems

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.

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

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

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

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

The passenger seat sensor may fail causing the SRS (airbag) light to illuminate. This problem has turned into a recall on some vehicles. Please contact you local dealer to see if your particular car is included. For more information on this recall, please click here»

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.

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

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

                            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.

                            The steering wheel position sensor may fail causing the Service Stability message to be displayed.
