I EXPERIENCED A PROBLEM WITH 2006 TACOMA LURCHING. PREVIOUS INCIDENTS WERE MINOR IN NATURE WITH VEHICLE LURCHING FORWARD WHEN STARTING FROM A STOPPED POSITION. NO REAL PATTERN WAS NOTED SO THE PROBLEM WAS NOT REPORTED TO DEALER. MY HUSBAND ADVISED ME TO REPORT THE PROBLEM TO THE DEALER DURING NEXT SERVICE VISIT. TODAY (NOVEMBER 20, 2008) WHILE PARKING IN FRONT OF A WENDY'S THE VEHICLE SUDDENLY LURCHED FORWARD CAUSING THE VEHICLE TO GO OVER THE CURB AND STRIKE THE BUILDING DOING CONSIDERABLE DAMAGE TO THE TACOMA AND THE BUILDING. THE VEHICLE HAS 33,356 MILES AND WAS PURCHASED NEW IN SEPTEMBER 2006. I NOTED SIMILAR REPORTED INCIDENTS INVOLVING THE TACOMA WHILE SEARCHING THE INTERNET -- INCLUDING A NHTSA ACTION ITEM DP08001 FOR WHICH THE AGENCY INVESTIGATOR WAS UNABLE TO DETERMINE A CAUSE FOR THE REPORTED PROBLEM. WE BELIEVE IT IS IMPORTANT TO REPORT OUR EXPERIENCE TO ENSURE THAT A POTENTIAL DEFECT IS FULLY INVESTIGATED AND THE PROBLEM CORRECTED. IF A PERSON WAS IN FRONT OF MY TACOMA WHEN IT LURCHED FORWARD SOMEONE COULD HAVE BEEN SERIOUSLY INJURED OR KILLED. A POLICE REPORT WAS MADE, WHICH CAN BE PROVIDED UPON REQUEST. WE ALSO TOOK PICTURES OF THE DAMAGE. *TR
