Lumina Stater Noise

My daugter's '96 Lumina 3.1 makes a grinding noise at the stater motor as the key is released after the engine fires. Starts and runs fine otherwise. Maybe the drive is staying engaged for a moment too long? Has anyone else had the problem - is it the ignition switch sticking or the stater drive itself sticking? How to fix???Thanks for any help.

I also I have this problem with my car thank god one day to another arrangement will not remember how but nothing solved the hope you have a good answer greetings from chile

Sounds like the armature isn't pushing the pinion as far as it should to engage the flywheel.

Worth checking.
