How many miles per gallon does a 2009 Toyota Sienna get?

The 2009 Toyota Sienna generally gets about 19 miles per gallon combined, with front‑wheel drive models averaging roughly 17–18 mpg in the city and 23–25 mpg on the highway, while all‑wheel-drive versions come in a bit lower.


Engine and drivetrain influence


The 2009 Sienna was powered by a single 3.5-liter V6 (2GR-FE) in the U.S. market, paired with a 6‑speed automatic transmission. Front‑wheel drive is standard, with all‑wheel drive available as an option. Drivetrain is the primary factor behind mpg variation, along with load, terrain, and driving style.


EPA fuel economy estimates


The following EPA estimates reflect official ratings for the U.S. market in model year 2009.



  • Front-wheel drive (FWD), 3.5L V6: approximately 17–18 mpg city and 23–25 mpg highway; combined about 20 mpg.

  • All-wheel drive (AWD), 3.5L V6: approximately 16–17 mpg city and 22–23 mpg highway; combined about 19–20 mpg.


Real-world mileage can differ based on driving conditions, cargo load, tire maintenance, and overall vehicle upkeep. Urban stop‑and‑go driving typically reduces mpg more than steady highway cruising.


How this translates for everyday use


For prospective buyers or current owners, the numbers above provide a baseline. A well-maintained 2009 Sienna with reasonable highway use should meet the EPA ranges, while heavy loads, frequent acceleration, or poor tire pressure can push fuel economy lower.


Tips to maximize mpg


Practical steps can help improve efficiency: keep tires inflated to the recommended level, minimize excess weight, drive smoothly with steady acceleration and braking, and perform regular maintenance such as air filter and spark plug checks.


Summary


The 2009 Toyota Sienna’s fuel economy hinges on drivetrain. Typical EPA estimates place it around 17–18 mpg in the city and 23–25 mpg on the highway for FWD models, with AWD versions trailing about 16–17 mpg city and 22–23 mpg highway. Combined mileage generally falls in the 19–21 mpg range. Real-world results vary with conditions and maintenance.

Is the 2009 Toyota Sienna a good year?


The 2009 Toyota Sienna is unchanged from last year, but it remains one of the best minivans you can buy. Competition is fierce in this segment, but the Sienna boasts Toyota's familiar 3.5-liter V6, an all-star engine renowned for its smooth power and laudable fuel efficiency.



Which lasts longer, Toyota Sienna or Honda Odyssey?


Which lasts longer, the Toyota Sienna or Honda Odyssey? While both minivans are designed to last for a long time, the Honda Odyssey currently has a higher J.D. Power reliability rating than the latest Toyota Sienna to be rated,3, 4 which suggests that it may be able to last for longer.



What year to stay away from Toyota Sienna?


The Toyota Sienna years to generally avoid are the 2004, 2005, 2007, 2008, 2011, and 2017-2018 models due to common issues like sliding door problems, transmission troubles, and engine/suspension concerns. While many Siennas are reliable, these specific model years have more reported complaints and recalls.
 
Model years to avoid

  • 2004: This first year of the second generation had the most owner complaints, particularly for sliding door issues. 
  • 2005: This year is associated with problems such as a faulty automatic sliding door and climate control issues. 
  • 2007: The 2007 model is often cited for engine and transmission problems, as well as recall issues with the transmission shift lever assembly. 
  • 2008: Common problems include minor electrical issues and airbag/seat belt concerns. 
  • 2011: This model year is known for premature suspension wear and engine problems, including stalling and rough idling. 
  • 2017-early 2018: The 8-speed transmission in these models has been linked to issues like whining, jerky operation, and oil leaks. 

Other considerations
  • Some sources suggest avoiding the 2006 model due to problems like failed oxygen sensors and sludge buildup, though it is still considered reliable overall. 
  • While the 2011-2016 models with the 6-speed transmission are generally considered reliable, the 2017-2018 models with the 8-speed transmission are the ones to approach with caution due to transmission problems. 
  • Regardless of the model year, it's always wise to get a pre-purchase inspection from a trusted mechanic before buying any used car.
