I call this a "Panic breaking defect" I have experienced this on two different GMC vehicles manufactured 14 years apart. The first was a 1999 GMC suburban with mechanically operated throttle control. The second was my present GMC Yukon XL Denali with electronic throttle control. The defect: The close proximity of the accelerator pedal to the brake pedal makes it possible to have the right foot on both pedals at the same time. This results in high engine RPM and full breaking pressure, however, the anti-lock breaking system releases and re-applies the break pressure repeatedly allowing the vehicle to lunge forward a short distance on each cycle. To remove ones foot from the both pedals so as to apply it to just the break would result in the vehicle, engine being at high RPM, to allow the vehicle to speed forward resulting in a serious collision. True one could use the left foot, if able, on the break and then remove the right foot, allowing the engine to return to idle but on modern automatic transmission equipped cars where the left foot plays essentially no part in driving, such an action is not likely to occur. Also the ignition key could be turned off but with both hands employed to apply maximum pressure on the steering wheel to ensure maximum braking effort, that is not likely to occur either, besides that would result in lack of power steering and vacuum boost to the break system. A proposed solution: In a drive by wire environment it would be simple to send an idle signal to the throttle body every time the break pedal is pressed and this is the condition which occurs in a normal breaking situation. I have related this to the service manager of my local dealer and have also communicated it to General Motors Customer Support even offering to demonstrate the problem but have received no response. After all I am only a lowly customer and it matters not that I am also a retired Engineer!

Monday 5th 2022, (2pm)I was driving with the AC on high as I had just left the mall. The interior was hot. As I left the mall and came to a stop light...the car would rev at stop, and continue to do so until the light changed. I had the oil and transmission fluid changed at 135000. It is currently at 138000. I turned off the AC because it did not seem to work (to cool the car down) and rolled the windows down and open the sun roof. Tuesday 6th, I was leaving the store (4pm) and again I turned the AC on and approached a stop light. When I stopped at the light, the car started revving or idling in pulses again as it did on Monday, however as I went to turn right onto the street, there was no power steering at all. Startled, I pressed the brake, shifted into park, turned the SUV off. Then restarted the SUV and the steering had returned to normal. I kept the AC off and drove home.

Was told by my local dealer that they did not have to complete to recall unless I signed a document holding them blameless if they cracked my dashboard or cracked it worst than it already is. I declined to sign until I could investigate why I absolutely had to sign a document absolving GM of their bad design. I believe it to be unjust and insulting that we are required to choose between the safety of our vehicles vs the possible destruction of the interior due to GM's poor design. I did not get a picture of the document before I left the dealer but was told I could bring it back later if I wanted it fixed but I would have to sign the document.

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.

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.
