Problems with 2004 Toyota Sienna SUSPENSION

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 owners?

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.

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

2004 sienna le: failure of driver side front suspension spring in january 2012, passenger side in january 2013. each spring cracked causing vehicle to drop while in motion. metal in cracked areas appeared porous possibly suggesting flaws in metal during manufacture. 2013 failure included crack near middle of spring, with a sharp broken piece sticking out close to tire. thankfully occurred while parking/at low speed; failure at high speed may have resulted in puncture of tire/loss of vehicle control. 2012 failure included crack near top. photographs of the 2012 spring are available upon request. vehicle is in good condition, with only ~65,000 mi at time of first incident. driven on paved roads, light loads. body rust free with minimal surface corrosion of unpainted/undercarriage items. contacted toyota in 2012, filed case. was informed similar issues had not been reported, failure was not covered. noting extreme hazard posed by broken spring puncturing tire, encouraged further evaluation. obtained/replaced at my cost spring from local toyota dealer, had aligned. contacted toyota in 2013 regarding second failure. noted was second occurrence/extreme hazard posed by puncturing tire, encouraged further evaluation. obtained replacement/had aligned at my cost. ...

2004 toyota sienna xle minivan was at a body shop for another problem. the technician drove the van around and noted some strange feel in the steering and examined the front suspension. the rubber bushings in both control arms were cracked and falling apart leading to slop in the steering and movement of the front end. the shop advised that this could lead to loss of control and was a danger to driving. repairs had to be made that included replacement of both control arms since they come as an assembly. there are other reports of similar rubber bushing failures from other 2004 toyota sienna owners. this is a critical safety and quality problem a the vehicle should be subject to a manufacturer recall for repair. other symptoms are that the front tires (80k mileage warranty) are worn out after just 25k. *tr

I had taken my sienna to the dealer to fix the last recall for the liftgate. they must have done an inspection and told me i needed to replace the warn control arms at a cost of $1,755.00 and the high pressure power steering hose at a cost of $699.00. i was there in april to have work done and none of this was mentioned. i have 54,473 miles and asked at what mileage do the control arms usually break down and i was told simply at any time. *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 repairable. the vehicle did not come equipped with a spare tire. *jb

Run flat tires are unsafe. 2004 toyota sienna xle awd has oe dunlop sp sport 4000t dsst 'run flat' tires. car has 19,500 miles of moderate driving. dealer refused to rotate and perform alignment at 19,000 miles because tires were too worn. referred to dunlop who elected to do nothing. now, at 21,500 cords are visible on inside edges of front tires. a. the only available replacements (from tirerack.com) are $845 plus mounting and balancing ($142). b. 'run-flat' cars do not have spare tires, jacks or tire well for storage, so there is no practical way to switch to regular tires. c. dealer says that toyota will sell a kit that includes a mini-spare. requires reconfiguring rear of van. result means that there is no more storage well under rear seats. toyota will not give the kit to affected owners. they sell it for $1,300. d. a decision to stay with (and replace) the 'run flats' means an out-of-pocket expense of ~$1,000 every year. e. if toyota abandons the 'run flat' consumer is absolutely victimized. f. if ...

2004 all wheel drive toyota sienna wears tires down to metal cords on inside edges were extremely chopped at 11,000 miles and worn to metal by the time toyota replaced at 23,000 this is not a safe condition ,no one can expect to see seperated tire cords at 23,000 on ant production vehicle,,vehicle came with dunlops dsst 22560-17 and were replaced with bridgestone b380 runflats at toyotas expense .however this is a desiegn flaw in our opinion ,does the all wheel drive push and pull on suspension causing tire wear???,,we feels toyota needs to retofit suspension or come up with a runflat tire that can have normal wear.
