2009 Chevrolet Tahoe

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.

I have contacted [XXX] for my concerns. I sent pictures and videos. the metal harness that is usually located behind the car seats is stuck under the seat and I can't unloosen my daughters straps now thats she's grown some. its concerning because she can't even use her car seat at this moment.

The dash and front and rear lights keep going on and off. And I changed all my lights on from and rear and it still happens there is a smell coming from my glove box. I can show you in person so we can see what can be done to fix this problem.

The contact owns a 2009 Chevrolet Tahoe. The contact stated that while driving at an undisclosed speed, the contact noticed oil leaking from the vehicle with the transmission warning light illuminated. The vehicle was taken to an independent mechanic, where it was diagnosed that the JB Weld and the driveshaft had failed, causing the transmission to fail and needed to be replaced. . The vehicle was not repaired. The dealer was contacted;. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was not available. The VIN was not available.

Dash cover is falling apart, a well known defect. I worry that an airbag deployment could cause dangerous shrapnel to be projected throughout the passenger compartment causing injuries like skin cuts and eye injuries.

I Keep getting code p2138 car stalls check engine light turns on, stability control flashes. I have to erase code to get it drive again, but will do it again soon. Been doing it for 4+ years now. The worst time it has done it is when I'm in the freeway where I have to pull off to the side if I can, I almost got into a bad accident because of this issue. Took it to my mechanic and he says take it to the dealer. I've replaced gas pedal, throttle body and it still does it.

Incident

May 12, 2020

My vehicle's throttle position sensor malfunctioned while I was driving on a busy highway at 55-60MPH, causing it to suddenly enter limp mode and display the error code P2138. This resulted in a rapid and unsafe reduction of speed to 30MPH, then down to 15MPH posing a hazard to myself and other drivers. Despite replacing both the gas pedal and the sensor itself in an attempt to rectify the issue, the problem persists. There are no prior reports made to the police, dealership, or insurance company regarding this matter.
