I HAVE A REMOTE START SYSTEM ON MY TRUCK, I REMOTE START MY TRUCK. THE TRUCK WAS PARKED ON A LEVEL SURFACE, NOSE POINTING IN TOWARDS HOUSE. THE DRIVEWAY DROPS OFF INTO A SLOPE, BUT THE TRUCK WAS ON THE FLAT SURFACE AREA. WE GO OUTSIDE TO GET IN IT, AND IT'S GONE. IT'S NOT IN THE DRIVEWAY AND IT'S NO WHERE TO BE SEEN. I LOOK OVER TOWARDS THE CREEK, NOPE NOT THERE. LOOK OUT FRONT, THERE'S MY TRUCK AND IT IS BACKED UP ON HALF IN THE STREET HALF IN THEN THE FRONT YARD. IT'S SITTING WHERE OUR MAILBOX SHOULD BE. IT IS RUNNING AND SIDE MARKER LIGHTS ARE LIT. I GO LOOK, OPEN THE DRIVERS DOOR TO SEE IF ANYBODY IS IN IT, NOPE, NOT A SOUL. IT'S IN PARK, THE 4 WD LO ALARM IS BEEPING, THE 4LO LED IS LIT ON THE DASH, HOWEVER, THE SWITCH/KNOB IS STILL ON THE 2WD MODE POSITION. I PRESS THE BRAKE PEDAL AND THE MOTOR CUTS OFF. SO THE REMOTE START SAFETY FEATURES WERE WORKING PROPERLY. I HAVE PHOTOS AND A VIDEO (DAY AFTER) SHOWING WHERE THE TRUCK LANDED AND THE PATH IT TRAVELED. I DO NOT HAVE ANY DOCUMENTS YET AS THIS OCCURRED LAST NIGHT. DEALERSHIP HAS THE TRUCK AND WILL BE EVALUATING THE REAR END AND DRIVE SHAFT, BUT INSURANCE WILL NOT PAY FOR INSPECTION OF THE TRANSMISSION. CAUSE OF ACCIDENT IS UNKNOWN, BUT SPECULATE SOMETHING IN THE TRANSMISSION FAILED WHILE PARKED.
