Toyota Sienna

Which Toyota Sienna years should you avoid?

Going by 8,554 owner complaints filed with NHTSA, the Toyota Sienna years to avoid are 2004, 2005, 2006, 2011 and 2010.

• 20042,062 complaints, 10.0× a typical Sienna year, most often about the body and frame.
• 20051,130 complaints, 5.5× a typical Sienna year, most often about the body and frame.
• 20061,017 complaints, 4.9× a typical Sienna year, most often about the airbags.
• 2011615 complaints, 3.0× a typical Sienna year, most often about the airbags.
• 20102.5× the usual share of fires, crashes and deaths for a car of its age (2 fires, 15 crashes, 1 death).

2 more years cleared the same bar; they are marked in the table below.

Better bets: among years old enough for a low count to mean something, the 2019, 2018 and 2014 drew the fewest complaints without an unusual share of serious ones.

How this is worked out: each year is compared with a typical year of the same model, which takes most of the difference in sales out of it, and its share of serious failures is compared with every other car of the same model year, because older cars were complained about differently. A year needs 25 complaints to be judged at all. Complaints are unverified owner reports. Full method →
