NHTSA investigations

NHTSA has opened 1 investigation that names the 2011 Toyota Sienna; it is still open. An investigation means NHTSA is reviewing reports of a problem. It is not a finding that the vehicle has a defect.

Desiccated air bag inflator rupture

Engineering analysis EA21002Open since Sep 17, 2021

From 2000 through 2017, Takata produced millions of air bag inflators using two types of phase-stabilized ammonium nitrate ("PSAN") propellant - propellant 2004 and propellant 2004L.

NHTSA listing: SIENNA. Component: Air bags (frontal, driver side, inflator module, passenger side). This investigation names 352 models.

An engineering analysis is a deeper review, usually opened after a preliminary evaluation. NHTSA lists investigations by make, model and model year only, so one can apply to only some versions of a model, such as one engine; its summary says which.

What owners report

Owners have filed 614 complaints with NHTSA about the 2011 Sienna. Below, they are sorted by the problems owners describe and by the areas NHTSA files them under. NHTSA does not verify complaints.

Problems owners describe

Counted from the complaint text: a complaint counts once for each problem it describes (how we match them). Some complaints describe none of these. Compare other models in the problem owners report most for every model year.

Areas named in complaints

A complaint can name more than one area, so shares add up to more than 100%. Mileage is shown where at least 15 owners reported it.

Toyota Sienna recalls and complaints by model year

The highlighted bars are the 2011 model year. Newer model years have had less time on the road, so their counts are lower. Counting complaints filed in each model year's first three years, the 2011 Sienna drew the most (136).
