MY VEHICLE IS ONLY 3 YEARS OLD AND THIS SHOULD BE REPLACED UNDER WARRANTY AND/OR A SAFETY RECALL. DUE TO IT BEING OUTSIDE ITS 36K WARRANTY, GM WILL NOT REPAIR IT.

BY DESIGN THIS TRUCK WILL TURN OFF MY TRAILER BRAKES WHEN THERE IS AN ISSUE WITH ANYTHING ASSOCIATED WITH THE ANTI LOCK BRAKE SYSTEM. I HAVE HAD TWO NEAR MISSES, CATASTROPHIC ACCIDENTS IN THE LAST TWO WEEKS AS A RESULT OF THIS CONDITION. I LOAD THIS MACHINE UP TO ITS MAXIMUM TRAILER CARRYING CAPACITY ON A DAILY BASIS. THIS MACHINE IS OPERATED IN THE MOUNTAINS OFTEN. THE 2 NEAR MISSES WERE AS DESCRIBED HERE. 1ST: I WAS APPROACHING A STOP SIGN WITH A HIGHWAY CROSS ROAD. CROSS TRAFFIC DID NOT HAVE TO STOP. WHEN I APPLIED THE BRAKES TO STOP AND I HEARD A TONE ACTIVATE THEN THE DIC INDICATED ABS NEEDS SERVICE, STABLI-TRAK NEEDS SERVICE, SERVICE THE TRAILER BRAKE SYSTEM. LUCKILY NO ONE WAS COMING BECAUSE AT THIS POINT MY TRAILER BRAKES WERE TURNED OFF BY THE TRUCK ON A FULLY LOADED TRAILER. I COULD NOT STOP AT THIS INTERSECTION. 2ND: I WAS TRAVELING DOWN A SLIGHT INCLINE TOWARDS A RED STOPLIGHT. I APPLIED THE BRAKES AND RECEIVED THE SAME WARNINGS AND THE TRUCK TURNED OFF THE TRAILER BRAKES ON A FULLY LOADED TRAILER AGAIN. THIS TIME I HAD A SEMI TRUCK COMING FROM THE RIGHT. THEY HAD TO PERFORM AN EMERGENCY STOP TO AVOID COLLIDING WITH ME AS I TRAVELED THROUGH THE RED LIGHT. THIS SYSTEM IS DANGEROUS AND NEEDS TO BE CHANGED.

EVEN THE DRIVERS DOOR SWITCHES ALL HAD TO BE REPLACED WHICH TELLS ME THAT THIS IS RELATED TO AN ELECTRICAL PROBLEM AND WITH SO MANY COMPLAINTS THE MATTER HAD FORCED CONSUMERS TO PAY FOR REPAIRS THAT WERE DESIGNED TO FAIL WITHOUT REGARD TO THE CONSUMERS SAFETY NOR FINANCIAL BURDENS. IT APPEARS THAT THE ELECTRICAL ISSUES WHICH MOST ARE DIRECTLY LINKED TO THE DEFECTIVE ENGINE WIRING HARNESS AND GROUNDING ISSUES AS MANY TECHNICIANS ARE REPORTING. AT THIS POINT THE TRUCK NEEDS TO BE TOTALED.

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.
