Known Problems

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

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 Check Engine Light may illuminate because of oxygen sensor failure. There may be no drivability symptoms detected though gas mileage may suffer.

 

The anti-lock brake system (ABS) and/or traction control light may illuminate. This can be caused by corrosion in the (ABS) wire harness connector at the right front wheel speed sensor due to water intrusion.  Corroded connectors should be cleaned or replaced as necessary to correct this concern.

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 well-documented and well-known issue with the Saab 9-3 built between 2003-2011 is harsh shifting from the 6-speed automatic transmission, and slight slippage between gears. This has been noted as hesitation to accelerate, especially from a stop.

Mainly, software issues have been to blame for these mishaps, but mechanical malfunctions related to shift solenoids and the valve body have also been major causes. Finally, the automatic transmissions in these models are sold as ‘sealed for life’, yet the transmission fluid does not seem to last the complete service life of the vehicle.

Correction of these issues often requires a simple software update, meaning the vehicle only needs to be plugged in, and the transmission controller receives new programming meant to fix these drivability concerns. In cases where this does not correct concerns, the transmission must be removed, inspected, and repaired, possibly requiring a complete rebuild.  

 

To mitigate these issues from escalating to a full transmission rebuild, many technicians recommend replacing the transmission fluid at regular intervals, yet the manufacturer has never offered this guidance. 

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.

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

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 conditioning expansion valve can fail causing poor, or no cooling from the AC system.
