My ignition key has been getting stuck in my 99 S70 Automatic. The ignition switch seems not to be turning all the way off, so the key won't come out. I have to restart the car, change from drive to park a few times, make sure the steering wheel is straight & after a few tries, the key comes out. WD 40 didn't help. Is this a common problem? If the switch is bad, is this an expensive job to fix? The car has 165k on the clock, so I've become accustomed to repairs "here & there".<p>Thanks for any help.
