RepairPal has identified the most common problems for 6 Saab models based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
Leaks in the air suspension can cause the air compressor to run constantly.
The trunk module can fail causing the tailgate to malfunction when opening or closing.
2.0L engines may become low on engine coolant with no cause found for the coolant loss. Our technicians tell us than in some cases the engine block may require replacement due to porosity.
A knocking noise while turning and/or a banging noise when driving on rough roads may develop in the front suspension. This type of noise is commonly caused by a front strut thrust bearing damaged due to water intrusion. Our technicians tell us revised thrust bearings are available to correct this concern.
Our technicians report failures of various components in the audio system. Speaker, control unit, and steering wheel button failures are all possible.
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.
If the engine will crank but not start, it may be the fuel pump has failed. Diagnosis may find no fuel pressure when attempting to start the engine.
The wiring for the transfer case speed sensor can fail causing sporadic operation of the AWD (All Wheel Drive) system.
Rear spring sensor malfunction can cause the rear suspension to sag requiring recalibration of the sensors.
The 2008-2009 SAAB 9-7x and 9-7x Aero use a throttle position sensor (TPS) which commonly fails and causes:
- Check engine light illumination
- Reduced Power message
- OBD trouble code P2135
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 thermo contact in the AC compressor can fail, which means the compressor may fail to engage or disengage.
