2004 Saab 9-3 Problems
RepairPal has identified the most common problems with the 2004 Saab 9-3 based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
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.
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 thermo contact in the AC compressor can fail, which means the compressor may fail to engage or disengage.
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.
The air blend system in the heating, ventilation and AC (HVAC) system can have problems, which can cause the AC controls to be stiff, or a lack of HVAC control.
The exhaust flex pipe can fail causing excessive exhaust noise from the front/center area of the vehicle. The flex pipe is a flexible joint in the exhaust that allows for engine movement.
