TWO KEY SAFETY SYSTEM WARNINGS ARE NOT DETECTIBLE UNDER NORMAL DRIVING CONDITIONS: 1) STEERING WHEEL SHAKE IF YOU DRIFT OUT OF LANE IS NOT FELT DRIVING UNDER NORMAL HIGHWAY CONDITIONS. 2) AUDIBLE ALARM IF YOU ACTIVATE THE TURN SIGNAL WITH A CAR IN YOUR BLIND SPOT CAN NOT BE HEARD OVER THE NOISE OF THE AIR CONDITIONER OR RADIO UNDER NORMAL VOLUME.

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. The rapid burning can cause the inflator to rupture during deployment, potentially causing serious or even fatal injury to vehicle occupants. See 2016 Blomquist Report at www.nhtsa.gov/sites/nhtsa.gov/files/documents/expert_report-hrblomquist.pdf.Consequently, all frontal inflators using propellant 2004 that do not contain a "desiccant" (a substance that traps and holds moisture) in US vehicles are under recall. These "non-desiccated" inflators either have been or are required to be replaced.In some cases, the remedy part for these recalled…
