WAS GOING TO BACK OUT OF MY GARAGE WHEN I PUT THE SHIFTER INTO REVERSE. WHEN THE SHIFTER WAS IN REVERSE, IT SHIFTED OUT OF GEAR ON ITS OWN INTO DRIVE AND IT WENT FORWARD SLAMMING FRONT END OF THE VEHICLE INTO A REFRIGERATOR. CAUSING THE REFRIGERATOR TO BE COMPLETELY DESTROYED AND THE FRONT END OF THE HOOD TO BECOME CROOKED. THIS IS VERY DANGEROUS AND CONCERNING AS HAD THEIR BEEN SOMEONE IN FRONT OF THE VEHICLE IT WOULD HAVE MORE THAN LIKELY SERIOUSLY HURT THEM OR KILLED THEM. I HAVE ALSO HAD OTHER INCIDENTS WHEN DRIVING THE VEHICLE THAT IT WILL SHIFT FROM DRIVE TO LOW ON ITS OWN AND THIS HAPPENS FREQUENTLY AT LEAST 3 TIMES PER WEEK. *TR
