Saab 9-5 Steering problems by year

This car had a simultaneous failure involving the steering, xenon headlamps and power train, specifically the all wheel drive system. All systems need to be replaced but gm has not made replacement parts available, has not corrected production errors in current parts. Current parts on market fail with 10000 miles.

Have a 2011 9-5 aero and just hit 58k. Very recently I've been noticing the popping/thudding when driving away quickly with the wheel turned, ex: when pulling away from a stop sign and turning left/right. I also can force the car to exhibit the binding/grinding deep noise when in first with the wheel turned almost at lock either right or left with very little throttle depression. Reading any saab forum I could, and speaking to dealers and reading service bulletins in relation to this car, all other saab vehicles...

Steering column lower u-joint became loose causing vague steering. U-joint is not correctly sized to take loads of steering input and over time becomes loose and noisy. This looseness causes the driver to overcompensate when driving. First notified in june, 2014. *Tr

I have owned a 2004 saab 9-5 sport combi wagon since 2006. Twice, over the last several years (2011, 2014), my husband and I have been on the highway and had an ignition switch incident where he was the driver and I was the passenger. In both incidents, I turned around to talk to my daughter (2011) and then daughters (2014) and inadvertently bumped the key in the ignition with my knee. The ignition switch is located in the center of the car by the console. It only took a slight tap of my knee and my car shut off while going at speeds of 75-80 mph on the highway. Fortunately, both times my husband was able to put the car into neutral and get the car off to the side of the road. *Tr

My saab was totalled on 11/15/99 because it began to roll from side to side when I made a quick lane change. This rolling had happened twice before in similar situations but I managed to regain control both times. The last time I was not so lucky. I h
