WHILE DRIVING ON THE HIGHWAY DURING A RAIN SHOWER AT ABOUT 60 MPH, WHILE USING THE WIPERS, THE DRIVER'S SIDE WIPER MADE A LOUD CRACK SOUND AND FELL OFF! I WAS UNABLE TO SEE AND NEARLY HIT THE VEHICLE IN FRONT OF MYSELF. SINCE IT WAS LATE SATURDAY NIGHT, I STOPPED AT A LOCAL PARTS STORE (ADVANCED AUTO) AND PURCHASED A NEW WIPER. WHEN THE CLERK INSPECTED THE BLADE, HE FOUND THAT THE WIPER ARM DOES SECURELY ATTACH WITH THE WIPER ITSELF. WHEN I CONTACTED THE DEALERSHIP, THE MAN I SPOKE WITH SAID HE COULD REPLACE THE WIPER ARM, HOWEVER THIS MAY NOT RESOLVE THE ISSUE WITH IT "FALLING OFF".

I HAVE OWNED A 2013 CHEVY SONIC FOR ABOUT 6 MONTHS NOW. THE OTHER DAY I WENT OUT TO DRIVE, SO I STARTED MY CAR WITH MY KEY FOB. AS I WAS ABOUT TO DRIVE AWAY I REACHED UP WITH MY RIGHT HAND TO TURN ON THE WIPERS. I HIT THE FOB FAIRLY HARD AND IT CAUSED THE KEY TO TURN, WHICH IN TURN SHUT OFF THE CAR. LUCKILY I WAS NOT DRIVING WHEN I WENT TO PUT THE WIPERS ON. EVEN MORE LUCKY WAS THAT I WASN'T DRIVING AND HIT IT HARD ENOUGH TO LOCK THE STEERING. I'VE HEARD THAT THIS WAS AN ISSUE IN OTHER VEHICLES AND IT WAS RESOLVED BY SEPARATING THE KEY AWAY FROM THE FOB SO THAT THE FOB DANGLED INSTEAD OF CREATING A LONG, SOLID KEY THAT COULD CAUSE THE ISSUE WHICH HAPPENED TO ME. YOU WOULD THINK WITH ALL THE IGNITION ISSUES GM HAS HAD, THEY WOULD HAVE COVERED ALL POSSIBLE PROBLEMS, BUT OBVIOUSLY NOT. I FEEL THE ONLY SOLUTION WOULD BE TO SEPARATE THE FOB FROM THE KEY SO THAT IT DOES NOT LOCK AND EXTEND SO MUCH THAT IT BECOMES AN OBSTACLE WHEN USING THE CONTROLS AROUND IT. THE KEY SHOULD BE SEPARATE FROM THE FOB. WHETHER PUT ON THE SAME KEY CHAIN OR NOT, THAT WOULD BE UP TO THE CONSUMER. *TR

1EA21002 · Desiccated Air Bag Inflator Rupture
Opened Sep 17, 2021 · No close date supplied
Status: open (inferred from source dates) · Air Bags:frontal:driver Side:inflator Module; Air Bags:frontal:passenger Side:inflator Module
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 inflators was, or will be, an inflator using either propellant 2004 or 2004L that does contain a desiccant. None of these "desiccated" remedy parts (which were installed in older model year vehicles) are currently under recall for a degradation concern. Certain subsets of desiccated PSAN inflators using propellant 2004 for use as original equipment, however, have been recalled for a degradation concern. All Takata inflators produced with propellant 2004L contain desiccant, and none of these desiccated inflators using propellant 2004L are under recall for a degradation concern. There have been no reported field ruptures in any non-recalled desiccated PSAN inflators.It is understood that desiccants fully saturate at some threshold, at which point any additional moisture will not be captured. This means the degradation process observed in non-desiccated inflators using propellant 2004 may also occur in non-recalled desiccated inflators using propellant 2004, assuming additional moisture enters the inflator and high temperature cycling occurs. Based on available information, desiccant saturation can occur within the first five years in the worst environments, and the time required for full saturation is affected by multiple factors. While no present safety risk has been identified, further work is needed to evaluate the future risk of non-recalled desiccated inflators using propellant 2004.Three entities -- Takata (now known as TK Global), the Independent Testing Coalition, and Exponent -- have been studying the long-term behavior of Takata desiccated PSAN inflators using propellant 2004L (as well as 2004) in the presence of moisture and temperature cycling. The research efforts, which include development of predictive modeling techniques and field sample analysis, are ongoing. To date, none of the researchers have identified field evidence showing that propellant 2004L is undergoing a degradation process that leads to aggressive deployment and potential rupture. However, the time in service of such inflators remains short compared to that of the inflators using propellant 2004. Further study is needed to assess the long-term safety of desiccated inflators using propellant 2004L.The Office of Defects Investigation is opening this investigation to examine whether a safety defect related to propellant degradation exists in non-recalled desiccated PSAN frontal inflators manufactured by Takata. This investigation will require extensive information on Takata production processes and surveys of inflators in the field. Lists of recall actions that may have used desiccated PSAN inflators as remedy parts, as well as the makes and models originally manufactured with them, is available with the downloadable version of this document (see nhtsa.gov/recalls?nhtsaId=EA21002 -- note this information is subject to change/revision as the investigation proceeds). This investigation does not supersede EA15-001, which remains open.
