I PURCHASED MY TRUCK ABOUT 1 YEAR AGO AND IT HAD 32,00 MILES ON IT, IT NOW HAS 40,000 MILES. EVERYTHING WAS FINE WITH IT UNTIL ABOUT MID-APRIL. I WAS DRIVING TO KALAMAZOO TO SEE MY DAUGHTER ON I-94 AROUND 72 MPH WITH THE CRUISE CONTROL ON. I TURNED ON MY LEFT TURN SIGNAL TO CHANGE LANES TO PASS THE PERSON IN FRONT OF ME AND TO MY DISMAY MY SPEED DROPPED DRASTICALLY AS THE CRUISE CONTROL DISENGAGED. THIS HAPPENED SEVERAL TIMES ON THE WAY TO KALAMAZOO THAT DAY. IT ALSO GOT WORSE ON THIS TRIP, SOMETIMES THE DOOR LOCKS WOULD LOCK AND UNLOCK, ALL OF THE LIGHTS ON THE DASHBOARD TURNED ON AND OFF AND EVERY TIME ANYTHING HAPPENED THE SPEED DROPPED, WHICH TO ME IS A SAFETY HAZARD AND SHOULD BE PART OF A RECALL. WHEN I GOT HOME THE NEXT DAY, I CALLED LEVALLEY GMC TO TAKE A LOOK AT MY TRUCK (WHERE IT'S BEEN SERVICED SINCE PURCHASE). WHEN I EXPLAINED THE SITUATION TO THEM, THEY CLAIMED THEY NEVER HEARD OF IT. THAT'S STRANGE BECAUSE IF THIS SITUATION IS GOOGLED, THERE IS A LOT OF INFORMATION ABOUT WHAT COULD BE WRONG. LO AND BEHOLD A DAY AND A HALF LATER MY TRUCK WAS FIXED AT A COST OF $1069.71 FOR DIAGNOSIS AND 3 CABLES, ALL POSITIVE AND NEGATIVE BATTERY CABLES. I CONSIDER THIS SITUATION A SERIOUS SAFETY ISSUE. I SENT A LETTER TO GM CUSTOMER SERVICE. LOU CONTACTED ME AND LEFT A VOICE MAIL WITH CASE NUMBER 8-4206988703 (6/4/18). I CALLED CUSTOMER SERVICE AND SPOKE WITH TONI ALSO 6/4/18. TONI REVIEWED THE CASE AND ASKED WHAT I WAS REQUESTING. I TOLD HER THAT THIS IS A VERY SERIOUS SAFETY MATTER THAT SHOULD BE ADDRESSED AND I WOULD LIKE TO BE COMPENSATED SOMEHOW. TONI STATED THAT THERE IS NO RECALL FOR THIS SITUATION AND THERE IS NOTHING THAT SHE CAN DO. I TOLD HER MAYBE THERE SHOULD BE A RECALL AND I AGAIN STATED THAT THIS IS A SERIOUS SAFETY ISSUE

ENTERING A HIGHWAY FROM A STOP, PROCEEDED TO ACCELERATE NORMALLY AND GRADUALLY. AFTER APPROX. SHIFT BETWEEN 1ST AND 2ND GEAR, THE GAS PEDAL WAS 'SUCKED' DOWN TO THE FLOOR AND REMAINED STUCK IN THAT POSITION. THE TRUCK LURCHED FORWARD AND BEHAVED LIKE IT WAS IN 'PASSING' GEAR. I TRIED TO TAP THE PEDAL TO RELEASE IT, BUT HAD NO EFFECT. I TURNED THE CRUISE CONTROL ON THEN OFF (DID NOT SET A SPEED) AND HAD NO EFFECT. I DEPRESSED THE BRAKES FAIRLY HARD WHICH SLOWED THE TRUCK DOWN, BUT THAT DID NOT RELEASE THE GAS PEDAL; AS SOON AS I LEFT OFF THE BRAKES, THE TRUCK AGAIN ACCELERATED AT FULL SPEED. ALTERNATING BETWEEN THE BRAKES AND TAPPING THE GAS PEDAL EVENTUALLY UNSTUCK THE GAS PEDAL.. NOTE THAT MY 'SPEED' WAS 0-50MPH WHEN I WAS ABLE TO UNSTUCK THE GAS PEDAL. I STATED THE INCIDENT OCCURRED AT (APPROX) 15MPH, THE SPEED WHEN SHIFTING BETWEEN FIRST AND SECOND.

On June 24, 2023 and as supplemented on June 25, 2023, the petitioner notified NHTSA he was withdrawing his petition. The petitioner indicated that, based on his review of data, there is no justification for asserting potential benefits that could be derived from actions sought by my petition. Based on the petitioner's withdrawal, DP22-005 is closed. Closure of this DP does not represent a determination by NHTSA regarding the subject matter of the petition.
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.

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.
