Known Problems

The ignition module or an ignition coil may fail causing an engine misfire, the Check Engine Light may or may not illuminate. Diagnoses will be required to determine the cause and needed repair.

The power steering assist may be lost intermittently along with illumination of the "power steering" warning message. In most cases, the power steering system will return to normal when the ignition is cycled off and the engine is restarted. General Motors recommends to replace the electric power steering assist motor to correct this problem. They have extended the warranty on the power steering assist motor to 10 years or 100,000 miles on most 2004-2007 Ion models. This is not a "recall" but an extension of the original warranty.

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.

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