2008 CHEVROLET SUBURBAN. CONSUMER WRITES IN REGARDS TO THE DISAPPOINTMENT IN THE MANUFACTURER DUE TO NUMEROUS VEHICLE REPAIRS. *SMD THE CONSUMER STATED THE VEHICLE WOULD RUN ROUGH, THE CHECK ENGINE LIGHT ILLUMINATED, THE SERVICE STABILITRAK AND TRACTION CONTROL LIGHTS ILLUMINATED WHEN SOME OF THE CYLINDERS SHUT DOWN, THE LIFTERS WERE NOT PROPERLY LUBRICATED, CAUSING THEM TO FAIL. THE ENGINE CONSUMED LARGE AMOUNTS OF OIL. THERE WERE NOISES COMING FROM THE OIL PAN AND TRANSMISSION AREA, 3 OF THE 4 DOOR LOCKS ACTUATORS WERE REPLACED, THE REAR LIFTGATE BROKE FOR THE 4TH TIME, THE RIGHT RETRACTABLE MIRROR WAS INOPERABLE, THE CRUISE CONTROL WORKED ABOUT 505 OF THE TIME, WHICH WAS PROBABLY TIED THE THROTTLE POSITIONING SENSOR GOING BAD AS WELL. ALSO, THE VEHICLE HAD SIGNIFICANT ELECTRICAL PROBLEM, WHERE CERTAIN LIGHTS WOULD ILLUMINATE ON THE DASHBOARD, THERE WAS AN AUDIBLE CLICKING NOISE, THAT SOUNDED LIKE A RELAY FIRING VERY QUICKLY. *JB

I PURCHASED A 2008 SUBURBAN LTZ IN JULY 2011. SHORTLY AFTER WE PURCHASED THE VEHICLE 3 OF THE DOORS LOCKS HAVE STOPPED FUNCTIONING COMPLETELY, THE 4TH DOOR WORKS SPORADICALLY (DRIVER SIDE, PASSENGER). THE LOCKS DO NOT WORK AT ALL WITH THE KEYLESS ENTRY NOR THE MAIN LOCK BUTTON FROM THE DRIVER SIDE DOOR. I HAVE BEEN TOLD THAT IT IS A PROBLEM WITH THE LOCK ACTUATORS MALFUNCTIONING AND THAT IT IS ALSO A WELL KNOWN ISSUE FROM VARIOUS DEALERS AND PER MY RESEARCH ON THE INTERNET. IN ORDER TO UNLOCK THE DOORS, I MUST MANUALLY USE THE KEY TO UNLOCK THE DRIVER SIDE DOOR THEN UNLOCK ALL THE OTHER DOORS BY HAND ONE BY ONE. THEN WE MUST LOCK ALL DOORS MANUALLY AFTER ENTERING BECAUSE THE LOCKS ALSO DO NOT LOCK AUTOMATICALLY WHEN YOU TAKE THE CAR OUT OF THE PARK POSITION. ALTHOUGH THE POWER LOCKS ARE A LUXURY, THIS ALSO BECOMES A SAFETY ISSUE. A VEHICLE WITH AN ORIGINAL ASKING PRICE OF OVER $55,000 SHOULD NEVER HAVE THIS ISSUE AND I'M NOT SURE WHY CHEVROLET FAILS TO TAKE ACTION FOR A CLEAR SAFETY DANGER. AS A MOTHER OF 3 CHILDREN I FIND THIS TO BE A VERY SERIOUS SAFETY ISSUE. A CHILD COULD EASILY OPEN THE DOOR AND FALL OUT OF THE MOVING VEHICLE OR IF WE WERE INVOLVED IN A CAR ACCIDENT ANY ONE OF MY FAMILY MEMBERS (ADULT OR CHILD) COULD POTENTIALLY BE EJECTED FROM THE VEHICLE, CAUSING EITHER SERIOUS INJURY OR WORSE!! I REALIZE THE CHILD SAFETY LOCKS CAN BE ACTIVATED TO KEEP A CHILD FROM OPENING THE DOOR ACCIDENTALLY, BUT THAT WILL NOT PREVENT A CARJACKER OR ANYONE ELSE FOR THAT MATTER FROM JUMPING IN AND STEALING THE CAR OR KIDNAPPING A CHILD. IN MY OPINION, THEIR DEFINITELY NEEDS TO BE A RECALL ISSUED FOR THIS MAJOR LOCKING MALFUNCTION BASED ON MY EXPERIENCE AND HUNDREDS OF OTHERS I HAVE RESEARCHED. *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.
