2008 Toyota Sienna Suspension Problems

VEHICLE WOULD ENGAGE BRAKES BY ITSELF AND VSC AND TRACTION CONTROL LIGHTS WOULD START FLASHING AND BEEPING WHEN GOING AROUND CURVES OR HITTING BUMPS IN THE ROAD. THIS WAS FRIGHTENING, AND CAUSED ME TO NOT IN GOOD CONSCIENCE SELL THE VEHICLE OUTRIGHT TO ANOTHER PERSON, SO I LOST THOUSANDS OF DOLLARS BY TRADING IT IN. THIS HAPPENED INTERMITTENTLY FOR OVER A YEAR. ESTIMATED FINANCIAL LOSS $4000.00. *TR

BOTH FRONT SPRINGS BROKE. PART OF THE LEFT FRONT SPRING CONTACTED THE TIRE, DAMAGING IT. IF VEHICLE WAS DRIVEN IT WOULD HAVE RIPPED THE SIDEWALL AND COULD HAVE RESULTED IN A CRASH. THIS WAS PRECEDED BY A CLANKING NOISE WHILE DRIVING.

SUSPENSION COIL SPRINGS BREAK AT VERY LOW MILEAGES (AROUND 40K OR 50K MILEAGES) IMPAIRING RIDE, STEERING AND BRAKING MAKING THE VEHICLE UNSAFE TO DRIVE. BESIDES THE SUSPENSION COIL SPRINGS CORRODING, THERE SEEMS TO A LARGER PROBLEM OF THE ENTIRE UNDERBODY CORRODING WITH THE TOYOTA SIENNAS.

IN 2015, HEARD A CLUNKING NOISE FROM FRONT END, TOOK TO DEALER WHO SAID IT WAS RIGHT FRONT COIL SPRING BROKEN. WAS REPLACED UNDER EXTENDED WARRANTY. IN AUGUST 2016, NOTICED CLUNKING IN THE REAR--THIS TIME THE RIGHT REAR COIL SPRING IS BROKEN. NOT COVERED.

I WAS DRIVING ON CITY ROADS AND NOTICED CLUNKING NOISE IN RIGHT FRONT PASSENGER SIDE BY TIRE ESPECIALLY WHEN I WOULD GO OVER UN SMOOTH ROADS OR RAILROAD TRACKS. PIECE OF BROKEN SUSPENSION COIL FLEW OUT ONTO THE ROAD. I WAS FORTUNATE IT DID NOT PUNCTURE THE TIRE. I TOOK INTO DEALER AND SHOWED THEM BROKEN PIECE AND FOUND THAT RIGHT REAR COIL WAS ALSO BROKEN BUT STILL INTACT. I HAD TO REPLACE BOTH COILS AT CONSIDERABLE EXPENSE. SINCE VEHICLE WAS NO LONGER MAKING NOISE I HAD TO INSIST THEY LOOK AT IT AND WAS CHARGED $69 TO JUST EXAMINE IT. THEN OF COURSE THEY SAW WHAT AN UNSAFE SITUATION IT WAS. THE BROKEN COIL LOOKED RUSTED TO ME IN SPOTS LIKE ITS A MANIFACTURERS DEFECT.

SINCE DRIVING MY 2008 SEINNA LIMITED OVER 61,000 MILES, I HAVE BEEN NOTICING METAL-RATTLING NOISES. I BROUGHT IT TO A MECHANIC, AND THEY FOUND THE FRONT, DRIVER SIDE SUSPENSION COIL SPRING WAS FRACTURED. I WAS TOLD BY THE MECHANIC THAT IT'S NOT COMMON, AND I CHECKED ANY RECALLS ON IT FROM TOYATA AND NHTSA WEBSITES. THERE ARE NO OPEN RECALLS, BUT ON THE INTERNET I SAW THE SAME PROBLEM HAPPENED TO 2008 SIENNA IN SEVERAL CASES.

THE LEFT REAR COIL SPRING BROKE. NOT SURE WHEN IT BROKE, WAS ADVISED IT WAS BROKEN BY A MECHANIC DURING AN INSPECTION.

TL* THE CONTACT OWNS A 2008 TOYOTA SIENNA. THE CONTACT DISCOVERED THAT THE FRONT DRIVER SIDE SUSPENSION COIL SPRING FRACTURED IN HALF. THE CONTACT WAS A CERTIFIED MECHANIC WHO DIAGNOSED THAT THE SUSPENSION COIL SPRING NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 87,000. UPDATED 4/6/15*CN UPDATED 2/2/2016 *JS
