REAR TAILGATE LATCH MECHANISM FELL OUT OF MOUNT. 2 OF 3 SCREWS WERE FOUND COMPLETELY LOOSE AFTER PARTIAL REMOVAL OF REAR TAILGATE INTERIOR TRIM. ISSUE HAPPENED IN STORE PARKING LOT LOADING GROCERIES; TAILGATE WOULD NOT LATCH SHUT AND DROVE HOME AT SLOW SPEED WITH ALL DOME LIGHTS ON (HONDA DOES NOT GIVE A POSITION SWITCH OPTION FOR ON*DOOR*OFF AS I HAVE SEEN IN MANY OTHER VEHICLES OWNED). DUE TO SERIOUS SAFETY ISSUE OF HAVING UNLATCHED TAILGATE OPTED TO EFFECT IMMEDIATE REPAIR UPON RETURN TO HOME ADDRESS. I HAVE REINSTALLED ALL 3 SCREWS AND USED BLUE LOCTITE THREAD LOCK AS IT APPEARS NO THREAD LOCK WAS PREVIOUSLY USED. I AM A MECHANICAL ENGINEER AND WAS CONCERNED THAT A) VERY SMALL DIAMETER SCREWS RELATIVE TO SIZE OF ITEM BEING SECURED AND B) NO LOCKING MECHANISM TO HOLD TORQUE ON THE SCREWS. THERE ARE MANY COMPLAINTS OF VARIOUS HONDA MODELS WITH SIMILAR ISSUE ON INTERNET AT HONDA OWNER DISCUSSION BOARDS. THERE ARE EVEN STEP BY STEP INSTRUCTIONS WITH PHOTOS HOW TO FIX POSTED ON A HONDA OWNERS DISCUSSION BOARD; YET WHEN I CHECK HONDA'S OFFICIAL TSB LIST - THERE IS NOT EVEN 1 TSB FOR THE TAILGATE LATCH LOOSE ISSUE; SO IT IS LIKELY MANY OWNERS (AS MYSELF) HAVE OPTED TO TAKE THE DIY APPROACH FOR THE SOLUTION. MY PROFESSIONAL OPINION IS THIS IS POORLY DESIGNED SINCE THE ATTACHMENT MECHANISM (3 SCREWS) TO HOLD THE LATCH BODY TO THE TAILGATE PANEL COULD BECOME LOOSE FROM NOMINAL IN-CITY DAILY DRIVING (PROOF THAT THE TORQUE ON THE FASTENERS IS NOT HOLDING UNDER NORMAL USE). *TR

I OWN AN 2008 HONDA PILOT (AUTOMATIC) AND WOULD LIKE AN INVESTIGATION OF THIS VEHICLE'S INABILITY TO HOLD IN GEAR ON AN INCLINE. THE PILOT WILL ROLL BACKWARDS WHEN IN DRIVE WITHOUT STOPPING ON AN UPHILL INCLINE, AND WILL ROLL FORWARD WHEN IN REVERSE ON A DOWNHILL INCLINE. I LIVE NEAR SAN FRANCISCO AND DRIVING IN THAT AREA IS NEARLY IMPOSSIBLE IN AN AUTOMATIC THAT WILL NOT HOLD ITS GEAR. IT IS WORSE THAN A MANUAL TRANSMISSION BECAUSE YOU CAN'T CONTROL THE GEAR ENGAGEMENT WITH A CLUTCH. I AM FORCED TO DRIVE WITH MY LEFT FOOT ON THE BRAKE AND RIGHT ON THE ACCELERATOR IN ORDER TO AVOID ROLLING BACKWARDS INTO FOLLOWING VEHICLES OR CROSS TRAFFIC. I BELIEVE THIS IS A DEFECT WITH NOT JUST MY VEHICLE BUT WITH ALL HONDA PILOTS PRIOR TO 2009, AS HONDA ADVERTISED THE 2009 MODEL WITH A NEW 'ANTI-ROLLBACK' FEATURE. THE 2008 MODEL IS LACKING THIS FEATURE, BUT I HAVE DRIVEN OTHER AUTOMATICS OF ALL OTHER TYPES AND SIZES AND NEVER HAD THIS PROBLEM. IN MY RESEARCH, IT SEEMS THERE IS A PROBLEM WITH SOMETHING CALLED A 'TORQUE CONVERTER' THAT COULD POSSIBLY BE RETROFITTED OR MODIFIED TO FIX THIS PROBLEM. I HAVE COMPLAINED TO THE HONDA DEALER IN MY AREA BUT WITH NO SATISFACTION. THIS IS AN EXTREMELY DANGEROUS ISSUE. AFTER ONE DAY IN S/F, STUCK ON AN UPHILL SLOPE IN GRIDLOCKED TRAFFIC, I COMPLETELY BURNED OUT MY BRAKES AND NEARLY STRUCK CARS BEHIND ME ON SEVERAL OCCASIONS. PLEASE INVESTIGATE AND RECOMMEND A METHOD OF RECOURSE AS I CAN NOT SEEM TO GET HONDA TO PAY ANY ATTENTION TO MY CONCERN. THANK-YOU. *TR

EA21002 · 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.

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.
