Q: 1995 Ford Taurus won't turn off

Hello! Sounds like you are now experiencing a common problem that many Taurus owners have experienced before. The problem is usually due to a broken plastic linkage in the steering column; the small plastic arm that connects the ignition cylinder to the ignition switch. It may break overtime due to aged material. That plastic arm is built into the steering column, so unfortunately the whole column must be replaced to fix the issue. In the meantime, to turn the vehicle off, you may press the inertia switch in the trunk. Pressing the switch will cut off the fuel supply to the engine and make it shut off. You can also have a mobile mechanic, such as one from YourMechanic, come out to the location of your vehicle to investigate the cause of your vehicle not shutting off.
