Question type: Maintenance & Repair

Engine will not shut off after removing key. Replaced battery three days prior. Had drove
the car for three days and about three hundred miles. Parked at house and a day later
my wife noticed odometer, oil pressure light, eml all fault lights lit on my dash. Car would
not start. Pulled all fuses and reseated them and tried starting the car and it worked.
Tried turning the engine off and it stayed running?
Bad ground, ignition switch?

I Have a Cooper S, 2003, same thing. Today I woke up to a dead battery after an 8 hr drive last night . Boosted it, started normal for -22 deg outside and then let it warm up for several minutes. I'm a mechanic and know the Coopers quite well and never had this before. I tried to shut it off and it stays running. With the key in my hand, the radio and blower fan turn off but that's it. Key feels stiff a little so am leaning towards ign switch. Heat is now also not working which happens 4 days ago so now the car it in my shop to warm up the car hoping it is just a freak frozen/no contact issue with the ign. sw. I drove car for 1 hr and it still would never shut off after several attempts and of course the interior never warmed up much. I will post back my findings...Thanks Ken

Turned out to be a bad reverse switch (manual transmission). Noticed lights would either flicker on and off or go out totally when shifted into reverse. Has been running fine for a week now.
