NHTSA Complaint #11208273 — 2003 TOYOTA 4RUNNER

EXCESSIVE AND PREMATURE CORROSION HAS DEVELOPED AT VARIOUS LOCATIONS ON THE VEHICLE FRAME SUCH THAT I AM CONCERNED ABOUT THE STRUCTURAL INTEGRITY OF THE VEHICLE FRAME AND IT'S IMPACT ON THE OPERATIONAL SAFETY WHEN I'M DRIVING THIS VEHICLE. IT APPEARS THAT THE CORROSION HAS ORIGINATED ON BOTH THE EXTERNAL FRAME SURFACE WELDED SEAMS AND ALSO FROM INTERNAL FRAME SURFACES. I TOOK PROACTIVE MEASURES TO HAVE MY FRAME TREATED FOR CORROSION RESISTANCE BY AN AFTER MARKET VENDOR IN AN ATTEMPT TO ABATE EARLY SIGNS OF CORROSION BUT THE CORROSION FROM INTERNAL SURFACES HAS NOW WORKED IT'S WAY THRU SHOWING CLEAR HOLES/GAPS/SEPARATION IN THE FRAME STRUCTURAL COMPONENTS. RUSTING FROM THE INSIDE OUT ADDS TO MY CONCERN ABOUT THE VEHICLE OPERATIONAL SAFETY. MY VEHICLE HAS HAD ALL REGULAR, SCHEDULED MAINTENANCE PERFORMED BY A TOYOTA DEALER WHOM HAS ALSO POINTED OUT THE STRUCTURAL ISSUES RESULTING FROM CORROSION. I LEARNED ABOUT AND WAS SHOWN THE CORROSION PROBLEMS DIRECTLY FROM THE DEALER SERVICE DEPARTMENT WHILE MY VEHICLE WAS ELEVATED ON A LIFT IN A SERVICE BAY. ATTACHED ARE PICTURES TAKEN RECENTLY (5/17/19) WHILE AT THE DEALER OF THE MORE OBVIOUS PROBLEMS AT VARIOUS LOCATIONS ON THE FRAME.
