Ok, so I have had my 2000 grand prix for 7 years now and I have had all these problems Here is what I did to fix them. OK first and easiest FREE fix is for the individual that could not get the key out of the ignition or turn all the way to off. There is a little piece of plastic or something close under the steering collum, pull that out (it's bassically a cover or plug) then there is a button up in there to release the key. Push that in and bang free, now the fix is ghetto but free and works just put something in there to hold that up and put the plug back in I used a piese of paper rolled and it's worked for say the last three years now, good luck. Now on to the ABS I had the wheel speed sensor go out on the drivers side and ended up replacing both fronts since I was at it and it was gone. Now mind you it is a good idea anyhow since grand prix's have a thing for the front bearings to go out especially the passanger front. So kill two birds with one stone. I was able to look on ebay and get some good prices on hubs and even oriellys was not bad, good luck with this one as well hope this info helps you all.

If the ABS sensor wire isnt put back inthe absolute lowest position it will come unpluged or break when steering or rough road driving its tight but must be done correctly

If you had your ball joints replaced this could cause the connector to be just a fraction to short. it will still clip together but it will pull just enough to break the wire signal to cause the lights to come on. I went to the wreckers and picked up two sensor clips cut them off extra long and re-wired it myself and I had the car for another 4-5 years with no issues.

Firestone told me my GP need rotors in the front after some insistance on my part they put it on the computer and it turned out to be a rear hub, $114 at advanced auto.

The trac light on my 2002 grand prix was caused by the sencer in the wheel bearing.

I had the same problem - it has to do with your front hub. Probably best to take into the dealership
