NHTSA defect investigations
Federal safety investigators have looked into a possible defect involving the 2014 Toyota Sienna:
Desiccated Air Bag Inflator Rupture
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. After prolonged exposure to high temperature cycles and humidity, inflators using propellant 2004 can degrade, causing the propellant to burn too quickly when ignited.

Wheels & tires
The van seems to prematurely wear tires out before their service life expectancy. I've owned the van for seven years, and I've had to purchase over five complete sets of tires. The front tires wear-out much faster than the rear tires, and do not last more than 15K miles. I've had several alignment jobs done, both (L&R) control arms replaced, ball joints, and struts - the van still wears out tires regardless of tire brand. I suspect the must be a design flaw causing premature wear and tear on tires on the front of the van, as I just replaced another set of tires from the Yokohama brand recommended for the van. I've asked Toyota, and they claim ignorance of such a problem. It is my desire to make this problem known, and to have the Government investigate if there is an design flaw in the Sienna van which is causing rapid part failures.
Tire pressure monitor system dashboard icon is ridiculously non-intuitive. Both my wife and daughter have been baffled by it because the icon DOES NOT LOOK LIKE A TIRE! Neither are stupid, one is a college grad and the other is a junior at ASU. The icon is a cross-section of a tire, and none of them know what a tire cross-section looks like. Because of this, they have driven on dangerously under inflated tires without knowing it. Fix the icon SO IT LOOKS LIKE A TIRE! Thank you.
