2004 TOYOTA SIENNA Suspension Problems

The slip indicator light and alarm comes on sporadically, engaging the ABS suddenly and unexpectedly, when we are on completely dry roads. Happens while driving 40-80 mph. And doesn’t matter if I’m going straight or turning.

TL* THE CONTACT OWNS A 2004 TOYOTA SIENNA. THE CONTACT STATED THAT THE VEHICLE FAILED AN INSPECTION DUE TO EXTENSIVE RUST, CORROSION, AND HOLES ASSOCIATED WITH THE FRAME (ENGINE CRADLE). AN INDEPENDENT MECHANIC DIAGNOSED THAT THE FRAME, ENGINE CRADLE, AND SUSPENSION ARMS MAY NEED TO BE REPLACED, OTHERWISE THE VEHICLE WAS UNSAFE TO BE DRIVEN AND THE PARTS MAY FRACTURE AT ANY MOMENT. THE VEHICLE WAS NOT REPAIRED. THE DEALER WAS NOT CONTACTED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE VIN AND FAILURE MILEAGE WERE NOT AVAILABLE.

THE VSC IS GOING OFF RANDOMLY, IN DRY, SAFE CONDITIONS. ALMOST ALWAYS WHEN I AM TURNING TO THE LEFT IN A LONG TURN. BUT HAS ALSO HAPPENED ON A WINDY ROAD, DRIVING 15MPH OR LESS, ON EVER SINGLE TURN SOMETIMES JUST THE ALARM, LIGHT FLASHING ON DASH & ENGINE DETHROTTLING, OTHER TIMES ADD THE STEERING WHEEL PULLING & BRAKES PUMPING THEMSELVES. WE HAVE HAD IT IN 3 DIFFERENT SHOPS & THE COMPUTER DETECTS NO CODES, ALL PARTS IN QUESTION (SUSPENSION, YAW, ROTATIONAL POSITION SENSOR, ETC) ARE IN GOOD WORKING ORDER, NOTHING LOOSE, WORN OR OTHERWISE NOT FUNCTIONING PROPERLY. WE HAVE HAD THE YAW SENSOR REPLACED AFTER READING MANY OTHER REPORTS OF THIS ISSUE, BUT IT DIDN'T HELP. WE LOVE OUR VAN, BUT IT IS NOW A DEATH BOX. WE NEVER KNOW WHEN THE VSC MALFUNCTION WILL ACTIVATE, MAKING THE CAR UNSAFE TO DRIVE. WHEN WILL TOYOTA ACKNOWLEDGE THIS & HELP...

TOOK SIENA IN TO TOYOTA FOR RECALL ON SPARE TIRE ASSEMBLY. WAS TOLD THAT WHILE UP ON THE RACKS, NOTICED BOTH REAR COIL SPRINGS WERE BROKEN AND NEED TO BE REPLACED ASAP.

WHEN I AM DRIVING MY 2004 SIENNA, ITS SHAKING SO BADLY I FEEL LIKE WHEELS GOING TO ROLL OUT. ALSO BRAKE MAKE WORSE, AND ENGINE MOUNTS AND TRANSMISSION MOUNT ARE VERY BAD CONDITION. I DON'T KNOW WHY ITS BAD BREAKING IN RAIN.

VSC SUDDEN ACTIVATION ON CURVES 35 MPH. BEEPING NOISE SLIP SENSOR COMES ON.

MY TIRES WERE GETTING WORN OUT AT ABOUT 20000 MILES, THOUGH I TOOK TO TOYOTA DEALER SHIP THEY NEVER IDENTIFIED THAT THE PROBLEM WAS WITH THE LOWER CONTROL ARM. RECENTLY IT WAS IDENTIFIED THAT BOTH THE LOWER CONTROL ARMS BUSHINGS WERE DAMAGED AND IT COST MORE THAN $1100 TO REPLACE IT. I UNDERSTAND THAT LOWER CONTROL ARMS WERE ON RECALL BUT MY VEHICLE WAS NOT PART OF THE RECALL / NEVER RECEIVED RECALL NOTICE. *TR

I HAVE CONCERN WITH TIRES AND LOW PRESSURE LIGHT ILLUMINATION . I HAD 15K SERVICE AT DEALER ON JULY 22, 2006 WITH 15,423 MILEAGE AND THEY SAID THE TIRE WEAR PATTERN FOR FOUR TIRES IS OK. ALSO DEALER ADJUSTED, INSPECTED AND ROTATED THE TIRES AT THAT TIME. BUT DURING 2,000 MILES DRIVES AFTER SERVICE, THE LOW PRESSURE LIGHT WAS KEEP COMING ON EVEN THOUGH I KEPT THE PROPER PRESSURE IN THEM. SO I WENT TO FIRESTONE FOR CHECK UP AND THEY INFORMED ME THAT I NEED NEW REAR TIRES. I WENT TO COSTCO FOR 2ND OPINION ON NOVEMBER 22, 2006 WITH 17,647 MILEAGES AND THEY INFORMED ME THAT I NEED TWO NEW REAR TIRES DUE TO WORN OUT. I WAS PRETTY UPSET AT UNUSUAL RAPID WORN OUT RIGHT AFTER MANUFACTURERS RECOMMENDED 15K SERVICE. I SEND THE LETTERS TO TOYOTA BUT THEY DON'T EVEN SEND A REPLY LETTER. *JB

DT*: THE CONTACT STATED THE ORIGINAL TIRES FOR THE VEHICLE WERE BALD AT 17,000 MILES. THE DEALERSHIP REPLACED THE TIRES WITH ANOTHER BRAND; THOSE TIRES ARE NOW BALD AT 30,000 MILES AND NEED TO BE REPLACED. THERE HAS BEEN NO INSPECTION FOR THE PROBLEM WITH THE VEHICLE.

2004 TOYOTA SIENNA DEVELOPED PROBLEMS WITH THE TIRES. ***NO ANSWER REQUIRED***. *MR AT 12,000 MILES, THE TIRES STARTED TO MAKE A RUMBLING NOISE IN THE REAR OF THE VEHICLE. UPON INSPECTION OF THE VEHICLE, IT WAS DETERMINED THE TIRES WERE SHOWING SIGNS OF WEAR ON THE OUTSIDE AND THE INSIDE, 1/3 OF THE REAR TIRES WERE CUPPING SO BAD THAT THE TREAD WAS WORN OFF IN SEGMENTS ALL AROUND THE INSIDE EDGE, OVERALL THE TIRES WERE DOWN CLOSE TO THE TREAD MARKERS. THE FRONT OF THE VEHICLE WAS SLIGHTLY OUT OF ALIGNMENT AND WAS THE CAUSE OF ALL THE PROBLEMS. THE CONSUMER ALSO STATED THAT THE RUNFLAT TIRE HAD LOW AIR PRESSURE DUE TO THE WARNING LIGHT ILLUMINATING. WHEN THE VEHICLE WAS TAKEN TO THE DEALER, HE WAS TOLD THERE WAS A NAIL IN THE TIRE AND THE RUNFLAT TIRE WAS UN-REPAIRABLE, HOWEVER THE OWNERS MANUAL STATED THE TIRE WAS...
