2010 jeep Cherokee wont shut off when key is out.
If you cannot get it to shut off, pull the negative battery cable.
You likely have a faulty ignition switch.
I’d pull the Ignition or fuel pump fuse first, let the engine die then take the negative cable off. if it’s a bad ignition switch the engine just might continue to run. An I don’t know how tolerant Jeeps are to running without the battery connected.
