Known Problems

Vehicles with a 6speed automatic transmission may develop one or more of the following faults related to a broken 35R clutch wave plate inside the transmission: Illumination of the Check Engine Light with code P0716, P0776, P0717, P0777, P2714, P2715, and/or P02723, loss of reverse gear, slipping or harsh 3rd or 5th gear shift. Removal and dis-assembly of the transmission will be required to replace the broken 35R wave plate. It is also extremely important that all debris from the failed part be cleaned from the transmission while it is disassembled in order to try and prevent future problems.

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.

A Loose or worn gas cap may cause Check Engine Light to illuminate. At this time, RepairPal cannot confirm a recall for this gas cap issue.

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 hoses commonly leak fluid. Any leaking hoses should be replaced.

The Saturn Astra may display the warning message "A/C off for Engine Protection" on the instrument panel. This may be accompanied by illumination of the check engine light and the temperature gauge reading cold at all times. This is a feature of the engine that is activated by the power control module when it detects the engine warming up too slowly. The OBD trouble code P0128 may also be stored. 

The cause is simply a worn out thermostat that stays open at all times, preventing the engine from reaching the proper operating temperature. 

Replacement of the thermostat will correct the issue. 

The 1996-2001 Saturn SW1 may display the warning message "A/C off for Engine Protection" on the instrument panel. This may be accompanied by illumination of the check engine light and the temperature gauge reading cold at all times. This is a feature of the engine that is activated by the power control module when it detects the engine warming up too slowly. The OBD trouble code P0128 may also be stored. 

The cause is simply a worn out thermostat that stays open at all times, preventing the engine from reaching the proper operating temperature. 

Replacement of the thermostat will correct the issue. 

The Saturn L100 may display the warning message "A/C off for Engine Protection" on the instrument panel. This may be accompanied by illumination of the check engine light and the temperature gauge reading cold at all times. This is a feature of the engine that is activated by the power control module when it detects the engine warming up too slowly. The OBD trouble code P0128 may also be stored. 

The cause is simply a worn out thermostat that stays open at all times, preventing the engine from reaching the proper operating temperature. 

Replacement of the thermostat will correct the issue. 

Many electrical problems can be caused by a failing Body Control Module or BCM. Before replacing, the system should be properly diagnosed to verify there are no other issues, such as electrical shorts or other failing modules. Remedying the condition requires replacement and programming of the Body Control Module.

The 2007-2008 Saturn Aura is known to 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.

The 2005-2007 Saturn Relay is known to 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.

The 2007-2009 Saturn Sky Redline is known to 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.
