What stands out
Among the 9 model years of Toyota Sienna in our records for suspension problems, this one ranks #2 by owner-complaint volume.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering suspension on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
Region Letter: Toyota will be sending Safety Recall Follow-Up Notices to remind owners whose vehicles have not yet had campaign repairs completed. Please note the following information for Regional and PD associates.

Toyota will be sending Safety Recall Follow-Up Notices to remind owners whose vehicles have not yet had campaign repairs completed. We request your assistance in completing the applicable campaign repairs as owners receive the Follow-Up Notice and contact your dealership. Please note the follow-up activity may cause an increase in your current campaign owner appointments. Toyota will continue with additional follow-up activities in the months to come.

The failure pattern owners describe
Coil spring failures dominate complaints about this generation Sienna's suspension. Rear springs corrode and fracture at the bottom coil or internal vein, sometimes both springs failing at once around 66,000 miles, sometimes one failing and its replacement failing identically months later. Front springs also break prematurely—one snapped at 82,700 miles mid-drive, another while parked in the garage. Owners describe rust visible at the fracture site and missing coating before failure. Repair costs run $1,000 for both rear springs; the pattern repeats so consistently that one owner, a materials engineer, views it as a design or production defect rather than bad luck.
Rear axle misalignment causes excessive tire wear; one owner replaced rear tires three times in 29,000 miles after a dealer identified the axle was out of spec but only swapped tires, not the underlying problem.
VSC and traction control lights activate randomly starting around 110,000 miles, triggering unexpected brake engagement during normal highway driving—curves, hills, speeds of 30–70 mph—with no fault codes stored. One owner rebuilt the front suspension and replaced CV shafts with no resolution.

Failure modes owners describe
Rear coil spring failure — corrosion and metal degradation
Both rear coil springs fail prematurely, typically with rust eating through the bottom coil or vein of metal in the wire, causing fracture at the coil support or 3/4 turn above the bottom. Owners report both springs failing simultaneously at the exact same location in some cases, or one spring failing, then the replacement failing in identical fashion months or a year later.
When: 66,000 miles (both rear springs); recurrence after replacement at ~110,000 miles in one case; varies by vehicle
Symptoms owners cite: Loud noise during driving or while parked; Loss of suspension support on rear axle; Uneven ride height; Visual rust or corroded vein visible at fracture site
Repairs/costs cited: $1,000 for both rear coil springs replacement at Toyota dealer; independent shops also performed replacements
Front coil spring fracture
Front passenger or driver side coil springs fracture without warning, typically at the bottom coil or 3/4 turn above the bottom. One spring breaks while parked in the garage overnight; another breaks at 30 mph. Corrosion and coating defects are observed at failure points.
When: 82,700 miles (front passenger side fracture); one failure while parked; one at 110,000 miles (driver side replacement that failed again in May 2013)
Symptoms owners cite: Loud noise and sudden fracture; Loss of front suspension support on one side; Visible rust or missing coating at break site
Repairs/costs cited: Front passenger side replaced by independent mechanic; driver side replaced under warranty on first failure, then owner paid for second replacement, then failed again
Rear suspension misalignment — excessive tire wear
Rear axle alignment drifts out of spec, causing rapid and excessive wear on rear tires. Dealer identifies the misalignment but does not repair the underlying axle, only replacing the tires. Rear tires must be replaced three times within 29,000 miles of service.
When: First identified at 12,000 miles; issue continues through 41,000 miles
Symptoms owners cite: Rapid rear tire tread wear; Rear axle out of alignment per dealer inspection
Repairs/costs cited: Tires replaced three times; underlying rear axle misalignment not repaired by dealer
VSC and traction control malfunction — spurious activation
VSC (Vehicle Stability Control) light and traction control light illuminate randomly during normal driving. When activated, the system unexpectedly applies brakes without driver input, potentially during highway curves or while accelerating uphill or downhill. No diagnostic trouble codes are stored; lights and brake engagement occur without apparent cause.
When: Beginning at 110,000 miles; on vehicles with lower mileage as well
Symptoms owners cite: VSC warning light comes on randomly; Traction control light activates without cause; Sudden brake application during curves (30–70 mph); Vehicle brakes on hills and straightaways; Loss of acceleration when VSC system engages; No codes stored in vehicle computer
Repairs/costs cited: Front end suspension rebuilt; CV shafts replaced; no resolution reported
Rear suspension recall — unsafe to drive
Manufacturer issued a recall for rear suspension (number unknown to owner). Recall notice stated vehicle is unsafe to drive. At time of complaint, no actual failure had occurred yet, but owner refused to drive vehicle due to safety concern stated on recall.
When: At 2,000 miles; recall issued
Symptoms owners cite: Recall notice for rear suspension safety
Repairs/costs cited: Owner requested manufacturer authorize dealer to tow vehicle for recall repair due to stated unsafe condition
Recalls/TSBs owners mention: Recall issued (campaign number unknown); manufacturer contacted but towing authorization unclear

Common questions
How serious is the suspension problem on the 2007 Toyota Sienna?
It's a documented issue but not catastrophic. 11 complaints have been filed. Repairs average $900 and most owners catch it before it causes a breakdown.
At what mileage does the suspension typically fail?
Based on the 11 complaints filed, suspension issues most often appear around 53,558 miles. Some report problems earlier; some make it well past 150,000 with no symptoms. Maintenance habits matter — vehicles that received timely fluid services and were not regularly overworked tend to last longer.
What does it cost to fix?
Independent shops typically charge around $900 for suspension repairs on this vehicle. Dealer pricing tends to run 20-40% higher. The exact figure depends on the specific failure mode, parts availability, and your local labor rates. If you're outside factory warranty, an extended service contract often covers this category.
Are there any recalls related to suspension?
No active recalls currently cover suspension issues on this vehicle. The complaints filed represent owner-reported failures that haven't risen to the level of a manufacturer-issued recall — but they're still worth knowing about before you buy or budget for repairs.
