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. Recently contacted Toyota; no new information available. Broken springs can result in loss of vehicle control as can tire puncture. Failures I experienced occurred at low speeds; if at higher speeds, results may have been catastrophic. Noting light use and excellent condition of vehicle as well as appearance of the broken springs, Toyota parts staff and outside mechanics indicated that manufacturing issues may be cause of failures. Replacement springs included different color coding; parts staff indicated this may correspond to more recent production, suggested that new parts may be of better quality.

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.

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.

: 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. ** answer required***. 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.
