According to Au7o's analysis of 5,485+ owner reports, the 2011 Toyota Sienna has 6 documented known issues. No issues are rated critical, indicating generally reliable ownership. The most commonly reported issue is Power Sliding Door Malfunction with 3,200 owner reports. Across all issues, repair costs range from $50 to $3,800. DIY maintenance guides at au7o.io.
On the 2004-2016 Toyota Sienna, power sliding doors on 2nd and 3rd gen Siennas are prone to cable fraying, motor failure, and latch mechanism issues. Doors may refuse to open/close, reverse mid-travel, or make grinding noises. The cable assembly inside the door wears and eventually snaps.
Replace the power sliding door cable assembly (Toyota 69631-08012 left, 69630-08012 right). Motor assembly replacement may also be needed (69634-08020). Latch assembly (69350-08021) is another common failure point. Some owners disable the power function and operate manually as a temporary fix. Labor is significant due to door panel and inner mechanism access.

On the 2004-2020 Toyota Sienna, the power sliding doors on the 2004-2020 Sienna are a chronic failure point. The steel cables that operate the door mechanism fray and break, the door motor burns out, and the roller assemblies seize. When the cable breaks, the door may become stuck partially open or closed, or the door may open/close erratically. The center cable is the most common failure point. Repeated use in cold weather, door obstruction events (hitting the safety reverse), and age all contribute to cable and motor wear. This is one of the most commonly reported Sienna issues across all model years.
Replace the failed sliding door cable assembly ($150-$300 for parts). If the motor has also failed, a complete door motor and cable assembly runs $400-$700. Labor is 2-4 hours ($300-$600). The door can be operated manually by disabling the power function until repaired (switch on the door jamb or dashboard). Lubricate the door tracks and roller assemblies annually with white lithium grease to extend cable life. Both sides should be inspected when one fails, as they wear at similar rates.

On the 2007-2020 Toyota Sienna 3.5L 2GR-FE, the 3.5L 2GR-FE V6 commonly develops oil leaks from the VVT-i oil line, timing cover, and valve cover gaskets. The VVT-i oil hose fitting loosens over time, dripping oil onto the exhaust manifold creating a burning smell and fire risk.
Tighten or replace VVT-i oil line and sealing washers (Toyota 15679-31010). Replace valve cover gaskets (Toyota 11213-31040 front, 11214-31030 rear). Timing cover reseal if leaking from that area. The VVT-i line fix is a $50 repair; valve cover gaskets run $300-600 due to rear cover access.

On the 2007-2020 Toyota Sienna 2GR-FE, the 3.5L 2GR-FE V6 in 2nd and 3rd generation Siennas can consume 1 quart of oil every 2,000-3,000 miles. Worn piston rings and valve stem seals are the primary causes. The issue is more prevalent in vehicles driven primarily in city stop-and-go conditions where the engine rarely reaches full operating temperature.
Perform an oil consumption test at the dealer (Toyota procedure involves sealing the oil fill and measuring consumption over 1,200 miles). If consumption exceeds 1 quart per 1,200 miles, piston ring and valve stem seal replacement is warranted. Using 0W-20 full synthetic oil and shorter 5,000-mile intervals can reduce consumption.

On the 2011-2020 Toyota Sienna, the front AC evaporator core in 3rd generation Siennas develops pinhole leaks from internal corrosion, causing gradual refrigerant loss. The AC system blows warm air intermittently, then fails completely. The rear AC system (if equipped) has a separate evaporator that can also fail independently.
Replace the front AC evaporator core, which requires dashboard removal (8-12 hours labor). Replace the receiver/drier and expansion valve at the same time. Evacuate and recharge the system with the correct amount of R-134a refrigerant (or R-1234yf on later models).

On the 2004-2020 Toyota Sienna, the hydraulic power steering rack on 2004-2020 Sienna models (non-hybrid, pre-2021) develops internal seal leaks that allow power steering fluid to weep from the rack boots or the input shaft seal. The leak starts slowly but progressively worsens, leading to low fluid level, groaning pump noise, and eventually heavy steering effort. The leak is typically visible as fluid dripping from the rubber boots at either end of the steering rack or from the area where the steering column connects to the rack.
A leaking steering rack should be replaced or rebuilt. A remanufactured steering rack runs $250-$500 for parts, with labor at $400-$800 (3-5 hours including alignment). A new OEM rack is $600-$1,200. As a temporary measure, topping off the power steering fluid and adding a stop-leak additive (Lucas Power Steering Stop Leak, $10) can slow a minor leak for several months. A four-wheel alignment ($100-$150) is required after rack replacement. The 2021+ Sienna uses electric power steering and does not have this issue.
