Apparently rodents have gone to the engine and ate the soy wires to the harness. This in turn has cost me over $1000 to fix. The only warning was when the warning lights came on and four runner started to shake when started.

PURCHASED VEHICLE BRAND NEW WITH 18 MILES ON IT. I GET IT SERVICED LIKE CLOCKWORK AND HAVE NEVER MISSED A MAINTENANCE APPOINTMENT. A LITTLE OVER A WEEK AGO, THE ELECTRICAL LOCKING SYSTEM ON THE DRIVERS SIDE DOOR STOPPED FUNCTIONING. TOYOTA IS TELLING ME THAT THERE ARE NO RECALLS AND IT WILL COST ME ALMOST $1000.00 TO REPAIR. NOW, THE ELECTRIC LOCKING SYSTEM FOR THE PASSENGER SIDE DOOR IS NOT WORKING AND TOYOTA IS STILL SAYING IT IS NOTHING THEY CAN DO BECAUSE THERE IS NO RECALL AND THE VEHICLE IS NO LONGER UNDER WARRANTY. THIS IS NOT ACCEPTABLE. ONE MINUTE THE LOCKING SYSTEM WAS WORKING WITH NO OBVIOUS SIGNS THAT SOMETHING WAS AMIDST, THEN ALL OF A SUDDEN, MY 4 RUNNER DOORS ARE NOT LOCKING. NOW THE COST IS DOUBLE AND THEY ARE SAYING THAT THE OTHER DOORS WILL SOON FOLLOW.
