Why do I have to hold the gear shift knob button to get the ignition to release

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! Dang! It sounds like you've exhausted all possibilities, but we'll get to the bottom of this! It sounds like there may be an issue with the interlock system. This system typically involves components in the shifter mechanism and the ignition switch. Since you've already replaced the shifter and lock actuators, it's possible there's a problem with the wiring or connections related to these components, or there could be a fault in the ignition switch itself. Remember, if you get a new ignition lock assembly, the ignition key will be different from your door key. If you have any other questions, please call us at 877-913-1554! We'll gladly find you a certified RepairPal shop in your area!
