2012 Mustang stalls
2012 Mustang stalls when rear seat passenger sits on drivers side.Believe it
or not. When a rear seat passenger moves from the right side rear seat to the
left side rear seat you can hear a high pitched buzzing and then in 5 to 10
seconds the engine stalls. Stay in the right side car runs fine for miles
Can you tell where the buzzing is coming from? Did you check for wiring harness close or under the seat?
Pulled the seat out. both sides have a bladder to sense when there is weight in the seat. For some reason the drivers side has a very sticky foil tape holding the bladder in place. The wiring harness leading into the bladder has a sort of electrical tape sleeve on the outside. Anywhere the electrical tape is not covering the wires that touches the foil tape causes a tweeting in the bladder and the engine dies. I will add some insulation to the wires and have already removed the foil tape. Just goes to show the power of duct tape! I hear about so many issues of stalling Mustangs I hope others read this and look towards these seat sensors for any issues.
Keep them "fat girls" out of that back seat.
