One problem related to ignition has been reported for the 2001 GMC Jimmy. The most recently reported issues are listed below.
I purchased a 2001 GMC Jimmy. Problem is ignition lock. Key stays in lock, have to fiddle with ignition move car, turn wheel to find just the right place. Thought just my car,but have seen others with same problem, local dealer said can fix for about 100 dollars they never looked at vehicle. Was told by gm on phone to push button on column to get key out, I don't have one was told book shows one any suggestion the vehicle fits my needs was really super low miles.
