The 2009 Sienna with the 3.3L V6 is generally reliable, but suffers from catastrophic oil consumption and engine sludge issues that can destroy the motor, plus a transmission oil cooler design flaw that's a ticking time bomb for the transmission.
Excessive Oil Consumption / Piston Ring Failure
Common · high severity
Typical onset: 80,000-150,000 mi
Symptoms: Burning through 1+ quart of oil every 1,000 miles, Blue smoke from exhaust on cold start or acceleration, Check engine light for misfire codes, Carbon buildup on pistons causing rough idle
Fix: This is the infamous Toyota 3.3L oil consumption defect. Piston rings fail and allow oil past into combustion chambers. Proper fix requires engine teardown, new piston rings, cleaning carbon buildup. If caught late, you're looking at short block replacement. 18-25 labor hours for full internal engine work.
Estimated cost: $3,500-6,500
Transmission Oil Cooler Line Failure
Common · high severity
Typical onset: 60,000-120,000 mi
Symptoms: Pink milkshake in coolant reservoir (coolant mixed with ATF), Transmission slipping or harsh shifts, Overheating transmission, Engine overheating in severe cases
Fix: The internal transmission cooler inside the radiator fails, allowing coolant and ATF to mix. Coolant destroys the transmission. Must replace radiator, flush entire cooling system AND transmission, replace transmission if contamination went too far. If caught immediately: radiator + flushes = 4-6 hours. If transmission damaged: add 12-18 hours for rebuild/replacement.
Symptoms: Ticking or knocking from valve train, Low oil pressure warning, Engine runs rough or loses power, Complete engine seizure in worst cases
Fix: The 3.3L is extremely sensitive to oil change intervals. Extended oil changes create sludge that blocks oil passages and starves bearings. If caught early, aggressive engine flush treatments might help (2 hours). If sludge caused bearing damage, you're into head gasket replacement or full engine rebuild territory. 20-30 hours for complete rebuild.
Symptoms: Clunking when shifting from park to drive, Excessive vibration at idle with vehicle in gear, Visible engine/transmission movement when accelerating
Fix: Hydraulic transmission mounts fail and cause harsh shift feel. Front and rear trans mount replacement. 2-3 hours labor depending on which mount(s).
Estimated cost: $300-600
EVAP System Canister and Purge Valve Failure
Occasional · low severity
Typical onset: 100,000+ mi
Symptoms: Check engine light with P0440, P0441, P0446 codes, Difficulty fueling (pump clicks off repeatedly), Fuel smell near rear of vehicle
Fix: Charcoal canister saturates or purge valve sticks. Replace canister and/or purge valve. 1.5-2.5 hours depending on component location.
Estimated cost: $400-800
Power Sliding Door Cable and Motor Failure
Occasional · low severity
Typical onset: 70,000-120,000 mi
Symptoms: Door opens partially then stops, Grinding or clicking noise from door track, Door won't latch properly, Error messages on dash about door system
Fix: Cables fray or motors wear out on power sliding doors. Cable replacement involves door disassembly and tensioning. Motor replacement is more straightforward. 2-4 hours per door depending on what failed.
Estimated cost: $500-1,200 per door
Owner tips
Change oil religiously every 5,000 miles with quality synthetic—this engine will NOT tolerate neglect
Check oil level every other fill-up starting at 80k miles; catching oil consumption early prevents engine damage
Inspect coolant regularly for any pink tint indicating transmission cooler failure—catch this immediately or lose the transmission
Consider external transmission cooler install as preventive measure (bypasses the failure-prone internal cooler)
Keep receipts for oil changes—Toyota had extended warranty coverage for oil consumption on some VINs
Buy only with complete service records showing religious oil changes and proof the transmission cooler was replaced preventively or monitored closely—otherwise you're gambling on a $5k-7k engine failure.

Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain 2005-2007 and 2009-2010 Toyota Sienna vehicles. In the affected vehicles, due to a problem within the shift lock assembly, the shift lever may be moved out of the 'Park' position without depressing the brake pedal.
Consequence: If the shift lever can be moved from the "Park" position without depressing the brake pedal and the parking brake is not applied, the vehicle may roll, increasing the risk of a crash.
Remedy: Toyota will notify owners, and dealers will replace the shift lock solenoid and reapply the grease, free of charge. Owners may contact Toyota customer service at 1-800-331-4331. Toyota's number for this recall is H0V. Vehicles that were previously recalled under campaign 13V-429 are not affected by this recall.

Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain model year 2004-2011 Sienna vehicles originally sold in, or currently registered in, Connecticut, Delaware, Illinois, Indiana, Kentucky, Maine, Maryland, Massachusetts, Michigan, Minnesota, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, Virginia, West Virginia, Wisconsin and the District of Columbia. The affected vehicles have a spare tire carrier assembly mounted under the vehicle whose attachment cable may corrode due to high concentrations of road salt splashing onto the spare tire carrier.
Consequence: If the carrier cable is corroded due to road salt, the spare tire may separate from the vehicle, increasing the risk of a crash.
Remedy: Toyota sent owners in August 2014 an interim notification to advise owners of the recall and that dealers will perform an interim remedy to remove the spare tire and relocate it to the luggage compartment, free of charge. Owners are being mailed a second letter as parts become available and dealers will replace the spare tire carrier assembly with an improved one, free of charge. The remedy campaign is being performed in phases. The first phase of the recall began July 7, 2015. Owners may contact Toyota customer service at 1-800-331-4331. NOTE: 2004-2010 Siennas subject to this recall were subject to recall campaign 10V-160 initiated in 2010. Those owners are advised that they must have their vehicles remedied again under this campaign and that having the earlier recall completed did not remedy their vehicles. Additionally, model year 1998-2003 Siennas were recalled as part of safety recall 10V-160. Owners of those vehicles that have not had not the remedy performed on their vehicles, should contact their Toyota dealer to schedule a free repair.
POWER TRAIN:AUTOMATIC TRANSMISSION · 13V429000
