NHTSA Complaint #11154401 — 2015 TOYOTA SIENNA

BRAKE SHAKING/SHUTTER UPON BRAKING DOWN A STEEP HILL. THE 2015 SIENNA AWD HAS 45,000 MILES. THE SIENNA HAS MOSTLY BEEN DRIVEN ON FLAT TO MILD SLOPED INTERSTATE ROADS THAT DO NOT REQUIRE BRAKING. RECENT INSPECTION BY A TIRE SHOP REPORTS 12/32 REMAINING ON BRAKE PADS SHOWING MINIMAL TO NO WEAR. UPON DRIVING DOWN A STEEP ROAD REQUIRING BRAKING TO CONTROL SPEED THERE WAS VIOLENT SHAKING/SHUTTER IN THE FRONT END. THINKING SOMETHING WAS BROKEN, REDUCED THE SPEED AND USED TRANSMISSION TO CONTROL SPEED TO REDUCE BRAKE APPLICATION. THIS RELIEVED THE VIOLENT SHAKING. CHECKING INTERNET THERE IS A TOYOTA TSB FOR THIS PROBLEM REPLACING BRAKE PADS AND ADDITIONAL WORK. THE PROBLEM HAS TO BE REPORTED TO TOYOTA WITHIN THE 36,000 MILE WARRANTY TO HAVE THE PROBLEM FIXED BY TOYOTA. THIS PROBLEM NEEDS TO BE FIXED BY A SAFETY RECALL WHEN OEM REMAIN ON THE VEHICLE.
