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.
What 2014 Lexus IS 350 owners say
Brakes
While driving on a major highway, I needed the brakes to be applied very rapidly as a vehicle cut me off and immediately slammed on their brakes. Upon my full and rapid pressing of the brake pedal, the emergency brake force distribution system braking did not appear to apply as on previously vehicles I've had or have including two large SUV's. Brake pedal was applied and pressed with full and complete force to the point that it no longer went any further. Continued in motion, no sliding, minimal ABS kicked in. And accident did occur as vehicle did not stop in time. Prior to and since then, I've paid more attention to the peddle pressure and level and sure enough, unless I prepump the peddle, the peddle must be pressed beyond what IS considered standard. If I prepump the peddle, then drive, the braking IS ultra sensitive. …
I purchased a 2014 Lexus IS 350 f sport from fort worth brothers, llc/Alfa Romeo Fiat in fort worth, texas on July 20, 2018. I noticed the next day while driving the car at highway speeds that when applying the brakes, there IS a "rumbling/grinding" noise and the car was hard to stop. I went back to the dealership the next day and told them. They checked the car and said they found nothing wrong and that they resurfaced the rotors. When I left the dealership, I continued to have the same problems with the brakes. I also told them that the car "shimmied/shaking" and "vibrated" very badly while driving and that the car needed new tires. They told me they had put new tires on the car, when, in fact, they had not. I continue to have problems with the car riding with a "shimmy/shaking" feel while cruising at 30-40 miles per hour. I finally took the car to sewell Lexus on August 1, 2018. …
