NHTSA defect investigations
Federal safety investigators have looked into a possible defect involving the 2016 Toyota 4Runner:
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.

Air bags
We were traveling down the mountain of Mt. Nebo in Dardanelle, AR, around 1:08pm on Friday, May 22, 2026. It had been misty rain for a few hours. As we were traveling down the switchbacks of the mountain, we pressed on the brake to slow the vehicle; however, the vehicle did not slow down any. Since we were coming to the next curve in the switchback, the decision was made to drive the car into a tree vs. risking flipping the car over the side of the mountain. When the vehicle collided with the tree, none of the air bags deployed. The point of impact was the front driver corner of the car. The car was traveling around 20 MPH at the time of impact (to the best of our knowledge). Problem #1-brake system failure Problem #2-Air bags failed to deploy -What component or system failed or malfunctioned, and is it available for inspection upon request? The brake system & air bags. …
On March 6, I was on South bound on Rt 29 in Culpeper County VA at the posted speed limit of 55mph when I hit a debris item on the road. I do not know what it was but it impacted the front skid plate and seems to be no other damage from the impact. There was no contact with the bumper, wheels or otherwise. There was no sudden change in speed or loss of control at all. The most dangerous result of this was the deployment of all the airbags (except passenger front airbag, there were no passengers). A police report was filed with Culpeper County Sheriff (case# 2603-0033) and my insurance agency (USAA claim # 016632631-800). The shop where the vehicle was towed (Ace Collision in Madison, VA) expressed surprise at the total deployment of the air bags given the scenario. …

This is a very common issue with 2015-2017 Toyota 4Runner TRD-Pro, it is a design defect in the way the coil spring terminates and sits on the top hat and bottom spring perch. Toyota has discontinued the defective parts and redesigned the spring perch on the updated strut and uses a different spring, but it is not recalled and should be as this is a safety defect. A broken coil spring can cause sudden loss of control of the vehicle resulting in a crash and even death.
