Sienna generations at a glance

  • 2008–2010 (end of the 2nd generation): a 3.5-liter V6 with a 5-speed automatic, front- or all-wheel drive.
  • 2011–2020 (3rd generation): a 3.5L V6 with a 6-speed, plus a 2.7-liter 4-cylinder for 2011–2012 only. For 2017 the V6 was redesigned with direct injection and an 8-speed, and it gained about 1 mpg.
  • 2021 and later (4th generation): hybrid only, with a 2.5-liter 4-cylinder and electric motors.

Sienna gas mileage by year

Going hybrid nearly doubled the Sienna’s mpg in city driving. A 2020 V6 is rated 19 mpg city and the 2021 hybrid 36, because the hybrid recovers energy when you slow down and can move on electric power at low speed. Choose a year to see every EPA version:

Sienna tire pressure

Most Siennas take 35 psi front and rear when the tires are cold. Some wheel sizes take 36 psi: the 19-inch tires on 2011–2020 models, the 18-inch tires on 2017–2020 models, and the 20-inch tires on 2022–2025 models. Some AWD and 18-inch versions came with run-flat tires; Toyota lists the same pressure for them. The label on the driver’s door jamb is the final word for your tires.

A minivan full of people and luggage is close to its load limit, so check the pressure before a long trip. If the warning light comes on: tire pressure light.

Sienna towing capacity

A Sienna can tow up to 3,500 lb when it has Toyota’s towing package. Without the package, the limit is much lower: 1,200 lb on 2008–2010 models, and 1,000 lb without trailer brakes on 2014 and later 3rd-generation models. The 2011–2012 2.7L 4-cylinder is rated 1,000 lb.

  • 4th generation (2021–2026): up to 3,500 lb10
  • 3rd generation (2011–2020): up to 3,500 lb4
  • 2nd generation (2008–2010): up to 3,500 lb3

Remember that the passengers and cargo count too: the load limit is on the door-jamb label.

Recalls: check by VIN

Enter your Sienna’s 17-character VIN at nhtsa.gov/recalls to see open recalls for your exact van. The VIN is on the dashboard at the base of the windshield, driver’s side, and on your registration. Toyota dealers fix recalls at no charge.

What to record in your log

  • Every fill-up. Hybrid mpg changes with the season and the trip; a log shows your real number. The MPG calculator does the math.
  • Each oil change with the grade (0W-16 on the hybrid) and the mileage.
  • Tire rotations, pressure checks, and any recall repair with its date.

Use a fuel log and a car maintenance log. The service intervals are on the Sienna maintenance schedule page, and Toyota’s system in general on the Toyota maintenance schedule page.
