THIS 2013 CHEVROLET TAHOE WAS PURCHASED IN AUGUST 2013. THE CHROME DOOR HANDLE ON THE PASSENGER FRONT DOOR JUST CAME OFF IN MY HAND AND HAD TO BE REPLACED IN AUGUST 2015. IN FEBRUARY 2016 THE DRIVERS SIDE FRONT DOOR HANDLE BROKE OFF AND ALSO HAD TO BE REPLACED. THE VEHICLE WAS PARKED AND I WAS ATTEMPTING TO OPEN AN UNLOCKED DOOR FROM THE EXTERIOR. I WAS TOLD THE CHROME DOOR HANDLES HAVE HAD ISSUES WITH BEING DEFECTIVE. ARE THERE ANY RECALLS, WHAT CAN I DO REGARDING REOCCURRING EXPENSES FOR REPAIRS ?
DASH IS CRACKING AROUND PASSENGER AIRBAG. VEHICLE IS GARAGE KEPT AND A SUN VISOR USED WHEN PARKED IN THE SUN. THIS VEHICLE HAS NEVER BEEN IN A COLLISION AND NONE OF THE AIR BAGS HAVE EVER DEPLOYED IN THIS VEHICLE. THE CRACK SEEMS COSMETIC BUT GIVEN THE LOCATION, I AM CONCERNED ABOUT THE INTEGRITY OF THE AIR BAG ASSEMBLY
DASHBOARD CRACKED VERY SMALL AREA BUT NOW IS CRACKING EVERYWHERE.
THIS VEHICLE WAS PURCHASED FROM MAC HAIK CHEVROLET IN HOUSTON, TX. ONLY ONE KEY WAS PROVIDED DURING THE VEHICLE PURCHASE. THE OTHER KEY WAS PROMISED IN AN "WE OWE YOU" STATEMENT, BUT NEVER RECEIVED.

THIS VEHICLE WAS PURCHASED FROM MAC HAIK CHEVROLET IN HOUSTON, TX. ONLY ONE KEY WAS PROVIDED DURING THE VEHICLE PURCHASE. THE OTHER KEY WAS PROMISED IN AN "WE OWE YOU" STATEMENT, BUT NEVER RECEIVED. AT SOME POINT IN TIME, IT IS BELIEVED THE 2ND KEY WAS USED TO ACCESS THIS VEHICLE AT UNDISCLOSED LOCATION(S) AND OR TIME(S) IN ADDITION TO ONSTAR APP ACCESS. THE VEHICLE BEGAN TO MAKE RUBBING SOUNDS WHEN TURNING CORNERS AND LOSING A LITTLE POWER. IN JULY 2014, I NOTICED MY VEHICLE SEEMED TO SHAKE WHEN GOING OVER SPEED BUMPS IN A MANNER INCONSISTENT WITH THE WAY IT NORMALLY WENT OVER SPEED BUMPS MOST TIMES AFTER VEHICLE DELIVERY. IN ADDITION TO, THE ENGINE SEEMED TO BE IDLING TOO HIGH AT NO SPEED AND IN A MANNER INCONSISTENT WITH THE WAY IT PERFORMED MOST TIMES AFTER VEHICLE DELIVERY. ALSO, THE DASHBOARD IS CRACKED AROUND THE AIRBAG. IN AUGUST 2014, I WENT BACK TO THE DEALER FOR INSPECTION OF THESE PROBLEMS. I WAS INFORMED REPAIRS WERE MADE TO THE FRONT DIFFERENTIAL OF THE VEHICLE AND THE TRANSMISSION WAS OVERFILLED. I WAS PROVIDED A STATEMENT OF THE WORK, BUT I FELT THE VERBAL EXPLANATION FOR THE WORK WAS TOO VAGUE BEING MY VEHICLE WAS IN THE SHOP FOR APPROX. 2 WEEKS. ON OR ABOUT OCTOBER 1, 2015 I CONTACTED THE GENERAL MOTORS CHEVROLET CUSTOMER REPRESENTATIVE AT THE PHONE NUMBER LISTED ON WWW.GM.COM AS (800) 222-1020. IN THIS PHONE CONVERSATION, I WAS INFORMED REPAIRS WERE NOT DONE TO THE FRONT DIFFERENTIAL, BUT TO THE REAR DIFFERENTIAL AND OR POWERTRAIN. NO WARRANTY REPAIR INFORMATION WAS ON FILE FOR ANY SUCH REPAIRS TO THE FRONT POWERTRAIN. I CONTACTED UPPER MANAGEMENT WITH THE DEALERSHIP AND THERE WAS NO ASSISTANCE PROVIDED TO ME IN PROACTIVELY RESOLVING THIS DISCREPANCY. I BELIEVE THIS VEHICLE MAY BE HAZARDOUS BASED ON THE DISCREPANCY OF REPAIRS AND SUPPLEMENTAL DEATH INSURANCE FOR ME BEING ATTACHED TO THIS VEHICLES VIN WITHOUT MY KNOWLEDGE.
THE ENTIRE FRAME AND ALL SUPPORTING BOLTS OF THE VEHICLE IS RUSTING AND ROTTING.
WHEN TRAVELING AT HIGHWAY SPEEDS THE CAR TOTALLY SHUT DOWN. COULDN'T GET OFF OF HIGHWAY, CREATING A VERY DANGEROUS SITUATION. HAD CAR TOWED TO DEALER ONLY TO FIND OUT THAT THE ENTIRE FUEL SENDING UNIT, FUEL LEVEL SENSOR, AND HARNESS HAD FAILED AT 37000 MILES AND NEEDED TO BE REPLACED.
I NOTICED A TINY CRACK IN MY DASHBOARD ON AUGUST 15TH. SINCE THAT TIME IT HAS GROWN 4 INCHES AND VEERED OFF ANOTHER 2 INCHES A DIFFERENT DIRECTION. MY VEHICLE IS GARAGE KEPT AND I AM A STAY AT HOME MOTHER. MY CAR IS RARELY PARKED IN THE SUN FOR LONG AMOUNTS OF TIME.

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.
