Known Problems

The GMC Canyon SLE and Canyon SLT uses a throttle position sensor (TPS) which is known to fail and cause:

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.

Illumination of the Check Engine Light can be caused by a loose or worn gas cap.

GM recommends replacing the engine coolant at 100,000 miles; however, our technicians tell us that the coolant may become contaminated and require a complete cooling system flush every 60,000 to 70,000 miles.

Our technicians highly recommend that the transmission is serviced every 30,000 miles to avoid problems and maintain optimal operating order.

Brake fluid can become dirty and may cause problems in the brake system; it should be flushed every 60,000 miles.
