Fuel economy data from fueleconomy.gov (EPA / U.S. Dept. of Energy). Annual cost based on 15,000 mi/yr at 55% city driving and current fuel prices. MPG is U.S. gallons; L/100km converted.
The dominant pattern in 2024 Sienna complaints centers on brake behavior. Owners frequently report the vehicle lurching or surging forward while the brake pedal is depressed, sometimes at a complete stop. Several describe the vehicle momentarily adding power or losing braking force mid-application, with no warning lights present, and the issue recurring across multiple incidents. Seats and vehicle structure each draw a smaller cluster of complaints, though at lower volume than the brake concern. A separate thread involves driver-side mirror vibration at highway speeds that owners say interferes with visibility during lane changes, with dealers in multiple reports characterizing it as normal operation. One isolated report describes a highway power-down event where multiple warning systems triggered simultaneously and the vehicle would not accelerate above 10 mph until towed.

By System
The 2024 Toyota Sienna has 3 recalls, all related to occupant and passenger restraint, with the most serious risk being that an unsecured wheelchair or loose restraint hardware could allow a passenger to move or be injured in a crash.
Two of the recalls affect wheelchair-accessible conversions. On vehicles converted by Rollx Vans, the wheelchair restraint latches may not secure the chair properly, allowing it to shift during transit. On BraunAbility-converted vehicles, tie-down pucks that anchor wheelchair occupant restraints may not have been tightened correctly and can detach in a crash. The third recall affects Sienna Hybrid models only: bolts on the third-row seatback recliners may not be properly tightened, meaning the seatback may not hold an occupant in place during a collision.
