My car has 260000 miles.
My car has an automatic transmission.

Check the wiring on the starter to the ignition switch and see if they are crossed on the solenoid of the starter. If the wiring is crossed, the starter solenoid will stay engaged as the starter is engaged. If the wiring is hooked up normal, then the ignition switch maybe damaged causing the starter to stay engaged. If you need further assistance with your starter staying engaged, then seek out a professional, such as one from Your Mechanic, to help you.
