What stands out
No new NHTSA suspension complaint has been filed on this vehicle in over 6 years — the issue may be aging out of the active population.
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.

The failure pattern owners describe
The 2006 Sequoia has a well-documented frame rust problem that owners describe as severe and safety-critical. Multiple owners report large holes in the frame, rust at weld seams, and rust on the rear axle housing and suspension components. The rust is aggressive enough that pieces flake off and end up in driveways. One owner hit a pothole and discovered the frame damage had progressed to the point where the vehicle now drives rough. Vehicles exposed to road salt (Kansas) or mag chloride (Colorado) seem especially affected, even when kept in covered parking.
Toyota issued a warranty program (campaigns ZH8 and HOF) acknowledging that frames were not properly treated during manufacture. However, owners report frustration getting repairs completed—one dealer said parts would be available, then later said the frame needed complete replacement and the campaign had ended before work could begin.
Separately, owners report front strut failures with broken and cracked components, ball joint failures occurring suddenly at both low and highway speeds, and one instance of a rear suspension link detaching during highway driving. One owner experienced excessive outside-edge tire wear on all four tires despite multiple alignments and ball joint replacement, suggesting possible underlying suspension geometry issues. A 2007 recall for front lower ball joints (Campaign 07V013000) had parts on back order as of late 2007 and wasn't completed in a timely manner.

Failure modes owners describe
Frame rust and corrosion
Owners report excessive, premature rust corrosion on frames, welds, and suspension attachment points. Multiple owners describe rust holes compromising structural integrity. One owner noted rust damage revealed after hitting a pothole. Toyota issued a warranty enhancement and service campaign (ZH8 and HOF) to address frames that were not properly treated at manufacture.
When: Noted at various mileages; one vehicle had 150,000 miles; salt/de-icing chemical exposure noted as accelerant in snow climates (Kansas, Colorado)
Symptoms owners cite: Large holes in frame; Rust at weld seams; Rust on rear axle housing and suspension components; Rust flaking off frame pieces in driveway; Rust on undercarriage; Rust on inside of rear hatch; Rough driving after pothole impact revealed frame rust damage
Repairs/costs cited: Toyota's HOF (Limited Service Campaign) offered CRC spray application at no cost within 2-year window from October 2018. One vehicle required full frame replacement; dealer work availability limited (one technician reported). Campaign ended January 2019 per one complaint.
Recalls/TSBs owners mention: Warranty Enhancement Notification ZH8 and Limited Service Campaign HOF issued due to frames not properly prepared and treated against rust corrosion at manufacture. Campaign had 2-year timeframe; one owner reported campaign ended January 2019.
Front strut failure
Owner reported front right strut bottom broken off and front left strut cracked and ready to break. No evidence of manufacturing defect or recall was found by independent mechanic.
When: Discovered during inspection for knocking noise at unknown mileage
Symptoms owners cite: Knocking noise from front right wheel area when going over bumps; Noise present even at very slow speeds over speed bumps; Bottom of front right strut broken off; Crack in front left strut
Repairs/costs cited: Front right and left struts replaced by independent repair garage. Owner retained broken strut piece showing fracture.
Ball joint failure
Two separate owners reported ball joint failures. First incident occurred at low speed during left turn; second incident at highway speed, resulting in loss of vehicle control and crash into median. Both failures were sudden and without warning.
When: One failure at 5 mph; second failure at 70 mph approximately one year later; another vehicle failed after 30 feet of driving at 15 mph
Symptoms owners cite: Ball joint failed without warning; Loss of vehicle control at highway speed; Ball joint broke and car fell to driver side
Repairs/costs cited: Ball joint replaced after low-speed failure. Second vehicle totaled after highway crash; no repairs performed.
Recalls/TSBs owners mention: NHTSA Campaign ID 07V013000 (Suspension: Front: Control Arm: Lower Ball Joint) recall issued March 2007 for lower ball joints. One dealer reported parts on back order as of November 2007 and had not completed repair by January 2008.
Premature and excessive tire wear
Owner reported unusual outside-edge tire wear on all four tires becoming bald, despite multiple dealer alignments and ball joint replacement. Issue persistent across tire brands (BF Goodrich, Bridgestone, Dunlop). Owner suspects suspension geometry flaw.
When: Observed between 10,000 and 21,000 miles; owner had been reporting issue for 11,000 miles
Symptoms owners cite: Outside edge wear on all four tires; Tires becoming bald; Wear present across multiple tire brands
Repairs/costs cited: Vehicle aligned three times by manufacturer dealers. Front ball joints replaced. District-level manufacturer inspection performed with no findings.
Recalls/TSBs owners mention: Dealer alignments performed three times and inspection conducted at manufacturer district level; no defect found despite owner's research indicating complaint pattern since 2002.
Rear suspension link detachment
Owner reported rear driver suspension link detached from vehicle during highway driving. Vehicle exhibited death wobble phenomenon with VSC warning lights. No repairs performed; manufacturer not notified.
When: Approximately 298,000 miles
Symptoms owners cite: Death wobble at 65 mph; VSC OFF and VSC traction and brake warning lights illuminated; Abnormal noise while driving; Rear driver suspension link detached
Repairs/costs cited: Vehicle not diagnosed or repaired.

Common questions
How serious is the suspension problem on the 2006 Toyota Sequoia?
It's a meaningful issue. 13 complaints have been filed and the failure mode causes operational problems for owners. Repairs average $900.
At what mileage does the suspension typically fail?
Across the 9 complaints that reported odometer mileage, most suspension failures cluster between 64,000 and 145,000 miles, with the median around 82,785. A quarter of owners report trouble before 64,000; a quarter make it past 145,000. Maintenance history matters more than the odometer alone — this is the reported failure window, not a guarantee.
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.
