Toyota Sienna Best and Worst Years

Counting owner complaints filed in each model year's first three years, the 2021 Toyota Sienna drew the most (97; most-reported area: brakes) and the 2020 the fewest (17).

Data: US EPA and NHTSAUpdated Sep 27, 2026

Every model year since 2016 in one place: EPA fuel economy, NHTSA recalls, owner complaints and crash test ratings. The best fuel economy rating, 36 mpg combined, arrived in 2021 and has held since. Every Sienna from 2021 is a hybrid.

Best and worst years, by owner complaints

Model years ranked by owner complaints filed with NHTSA in their first three years (model year Y: filed by the end of Y+2), so every year is measured over the same time on the road. Years without three full years of data, and launch or final years with very few sold, are left out. Counts are not adjusted for how many were sold.

Questions

Which Toyota Sienna years have the most problems?

Counting owner complaints filed with NHTSA in each model year's first three years, the 2021 (97) and 2022 (94) drew the most.

Which Toyota Sienna years have the fewest problems?

The 2020 (17) drew the fewest complaints in its first three years. The 2024, 2025, and 2026 are not ranked yet: they have had fewer than three full years on the road.

Which Toyota Sienna years should you avoid?

Complaint counts can't tell you whether a particular car is sound, but they show where owners reported the most trouble: the 2021 and the 2022, against 52 complaints in a typical Toyota Sienna year. Whatever the year, check the car's open recalls by VIN at nhtsa.gov/recalls before you buy. Safety recall repairs are free at Toyota dealers.

Which Toyota Sienna years have the most recalls?

The 2017 has the most safety recalls in NHTSA's file (10), then the 2019 (7). A recall can cover a problem that affects only a few cars, so open a year's page to see what each one covers. No recall for 2016 to 2026 models tells owners not to drive the car or to park it outside.

What are the most common Toyota Sienna problems?

Of the 1,148 owner complaints NHTSA lists for 2016 to 2026 models, the areas named most are seats (23%), brakes (19%), and body structure (8%). One complaint can name more than one area. The recalls and problems page for each year breaks this down further.

Which Toyota Sienna year has the best MPG?
