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 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.
