The failure pattern owners describe
The 2008 Sienna steering system spawns consistent complaints across multiple failure modes. Clicking and clunking noises in the steering column appear as early as 1,000 miles and worsen with age, particularly during right turns. Dealers have replaced CV shafts, driveshafts, and clock springs without success; one dealer applied special grease to the intermediate shaft with only temporary relief.
Power steering rack and pinion seals leak fluid, typically on the passenger side, starting as early as 57,000 miles on regularly serviced vehicles. Owners report replacements costing $900–$2,000 and recurring within 50,000 miles of the prior repair. One owner needed three rack replacements in six years.
Traction control and VSC engage without warning during normal highway driving, curves, and slight turns on dry pavement, triggering rapid braking, audible alarms, and sideways lurching. Multiple owners report dealers and mechanics cannot diagnose the cause or find any diagnostic codes. Recalibration and steering angle sensor recommendations have not fixed the issue.
Vehicle drift to the right requires constant steering correction and causes arm strain. Owners report decreasing turning radius and alignment fixes that don't hold. One filed a successful lemon law claim.
Intermediate steering shaft issues manifesting as choppy steering and alarming column noises have been documented; owner research indicates TSBs exist for other model years but Toyota states none apply to the 2008 Sienna.

Failure modes owners describe
Steering Shaft Clicking/Noise During Turning
Clicking, clunking, or chattering noise emanates from the steering wheel or column when turning, particularly to the right at low speeds or in parking. Owners report the noise starts early (around 1,000 miles) and worsens with mileage. Multiple dealers replaced CV shafts, driveshafts, and clock springs without resolution. One dealer attributed it to the intermediate steering shaft and applied special grease, with temporary relief (1,500 miles) before noise returned.
When: Low-speed turning, starting around 1,000 miles; worsens progressively
Symptoms owners cite: Clicking noise in steering wheel or column; Noise primarily when turning right; Noise felt and heard on steering wheel; Noise worsens with mileage
Repairs/costs cited: CV half shaft assembly replacement (unsuccessful); driveshaft replacement (unsuccessful); clock spring replacement recommended but owner declined; lower steering shaft replacement with special grease (temporary relief, ~1,500 miles); Toyota indicated special grease was ordered with high regional demand
Recalls/TSBs owners mention: One owner reported Toyota indicated it is a known common issue on all 2008 Sienna AWD vans; dealer requested special grease as a repair solution; TSB exists per owner research
Rack and Pinion Seal Leakage
Power steering fluid leaks from the rack and pinion assembly, typically on the passenger side. Leaks appear as fluid puddles under the vehicle or discover during service inspections. Multiple owners report needing rack and pinion replacement well before 120,000 miles. One owner required two replacements within 6 years; another needed replacement at 57,000 miles on a regularly serviced vehicle. Owner research indicates the problem is widespread among 2008 Siennas.
When: Starting as early as 57,000 miles; recurring within 50,000 miles of previous replacement
Symptoms owners cite: Power steering fluid leaking; Leak visible under vehicle; Typically passenger-side location; Rack boot torn or seal failed
Repairs/costs cited: Rack and pinion replacement cost ranges: $1,200–$1,300 (2011), $400–$900 (2013), ~$2,000 (estimated 2014); boot replacement temporary fix; replacement lasting approximately 50,000 miles before recurrence
Recalls/TSBs owners mention: Toyota covered $900 of $1,300 repair cost in one case (2013); owner noted it should have been full coverage; dealer indicated it is a very common defect; extended warranty (Cost Guard) expired and did not cover defect
Traction Control / VSC Unwanted Engagement
Vehicle stability control (VSC), traction control, and anti-lock brake system (ABS) engage unexpectedly during normal driving, triggering rapid deceleration, audible beeping alarm, and sideways vehicle lurching. Activation occurs on flat roads, curves, inclines, and declines with no actual loss of traction. Events happen at speeds from 25–60 mph, often during highway curves or slight steering input. Multiple independent mechanics and dealers cannot diagnose the cause, and diagnostic testing shows no codes.
When: Intermittent initially, becoming more frequent (daily after 6 months in one case); mileage 110,000–170,000 reported
Symptoms owners cite: VSC/traction control light illumination; ABS engages without brake application; Audible beeping alarm; Sudden braking/deceleration; Vehicle lurches to one side; Loss of acceleration during steering input; Slip indicator light activation; Occurs on curves, inclines, declines at 25–60 mph
Codes mentioned: Zero calibration code recorded in one case
Repairs/costs cited: No successful repairs reported; tire replacement attempted; brake and rotor replacement attempted; recalibration performed without permanent resolution; steering angle sensor installation recommended but not completed in one case
Recalls/TSBs owners mention: Steering angle sensor installation diagnosed by Fox Toyota; no repairs completed; manufacturer case number issued; Toyota customer service reported TSBs exist for prior/post-year vehicles but not specifically for 2008 Sienna
Steering Drift and Alignment Issues
Vehicle drifts or pulls persistently to the right even on straight, level roads and in the center of the road. Drivers must constantly hold the steering wheel to the left to maintain straight tracking, causing arm strain on longer drives. Problem occurs independently of road crown or surface conditions. One owner filed a lemon law claim; another reports decreasing turning radius over time.
When: Observed from early ownership; may relate to alignment or underlying steering component wear
Symptoms owners cite: Vehicle pulls/drifts right; Requires constant steering correction; Arm strain from continuous correction; Decreasing turning radius; Passenger-side steering fluid leak may accompany
Repairs/costs cited: No specific repairs documented as resolving the issue; alignment performed without permanent correction in at least one case
Recalls/TSBs owners mention: Dealer attributed to road crown; owner filed lemon law claim and received compensation; Toyota stated vehicle cannot be repaired per owner
Steering Column Noise and Intermediate Shaft Failure
Abnormal sounds originate from the steering column, ranging from ticking to alarming noises, particularly during turns at moderate to highway speeds. One owner reports almost losing steering control due to intermediate steering shaft failure, with very choppy, difficult steering. Research by owners indicates intermediate steering shaft corrosion as a known issue with TSBs for other model years.
When: Observed at 175,000 miles and other high mileage intervals; intermediate shaft issues common as vehicle ages
Symptoms owners cite: Abnormal ticking or alarming sound from steering column; Very choppy steering feel; Almost lost steering control in one case; Noise during turns
Repairs/costs cited: No repairs completed in the reported case; intermediate steering shaft corrosion identified in owner research as requiring replacement
Recalls/TSBs owners mention: TSBs issued for prior and post-year vehicles but not documented for 2008 Sienna per owner contact with Toyota customer service
Steering Wheel Centering and Braking Interaction
Steering wheel physically turns to the right when braking, especially noticeable as vehicle speed decreases or on downhill grades. Steering fails to center properly at all times, creating false feedback about road conditions (blamed on road crown when actually a vehicle defect). Issue particularly dangerous in snow, where driver may overcompensate thinking it is road surface.
When: Intermittent, most noticeable during braking, downhill driving, or low-speed maneuvers
Symptoms owners cite: Steering wheel turns right during braking; Steering does not center properly; False sense of steering feedback; More pronounced at lower speeds or on grades; Pulls to right during braking
Repairs/costs cited: No successful repair documented; one owner pursued lemon law claim
Recalls/TSBs owners mention: Dealer initially attributed to road crown; no repair solution provided
