Known Problems

The Check Engine Light may come on because the electronic throttle body has failed. Other symptoms include loss of acceleration, a high idle or failure to return to idle, and difficulty starting.

The 2008-2009 SAAB 9-7x and 9-7x Aero use a throttle position sensor (TPS) which commonly fails and 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.

If the HID head lights are flickering or have failed, it may be caused by the window washer fluid leaking onto the HID modules. The washer fluid check valve for the head light washers develops the leak and drips onto the modules mounted under the head light assemblies.

The Check Engine Light may illuminate because of air injection pump, and/or check valve failure. There may be no drivability symptoms detected.

The thermo contact in the AC compressor can fail, which means the compressor may fail to engage or disengage.

The direct ignition cassette can fail causing the engine to die while driving, and/or it will crank but not start. The engine may also have a rough idle and run roughly. Diagnosis may discover trouble codes for random misfires.

The wiring for the transfer case speed sensor can fail causing sporadic operation of the AWD (All Wheel Drive) system.

Oil leaks from the timing cover, valve cover, and/or rear main seal may be due to excessive crankcase pressure. An updated PCV (Positive Crankcase Ventilation) kit was released to fix this concern.

If the ignition switch is turned to the "lock" position when the vehicle speed is over 5km/hour, the ignition key cannot be removed from the lock cylinder. This is not a defect, but a normal design feature. In order to remove the key: Turn the ignition to the "on" position, wait several seconds, turn ignition to "lock" and remove the key.

The shaft for the air blend door can fail creating the inability to adjust the AC or heating temperature. The AC or Heat will not maintain the proper temperature.

Our technicians report failures of various components in the audio system. Speaker, control unit, and steering wheel button failures are all possible.

The trunk module can fail causing the tailgate to malfunction when opening or closing.

Oil can leak from the oil pressure sensor causing a loss of pressure at the sensor and illumination of the oil light.
