Most reported problems

Here are the complaint groups in NHTSA's file, biggest first.

These are unverified owner reports, and one complaint can name more than one part.

Recalls

Newest first. Each recall covers only certain vehicles, so not every 2008 Sienna is necessarily included.

Fuel economy

EPA ratings depend on the engine and drive. Annual fuel cost uses EPA's current fuel price assumptions, not prices when the car was new.

Complaints submitted to NHTSA by owners; unverified reports, one complaint can name several components. Complaint counts are not normalized by sales; compare years of the same model, not different models. EPA annual fuel cost uses EPA's current fuel price assumptions, not the price when the car was new. Horsepower is the rating listed for EPA test vehicles. Dimensions are Canadian-market specifications and can differ slightly from US models.
