Vehicle randomly throws Stabilitrak, Traction control and ABS codes. Engine derates to limp mode. Transmission goes to full line pressure shifts. A cycle of the ignition system will reset the system a majority of the time. There is no "recall" but the general consensus in the mechanical world is two things cause this issue. Throttle body is bad and/or the steering position sensor fails causing the stabilitrak system to be disabled (which in a 2013 Tahoe, stabilitrak cannot be turned off) I have replaced the throttle body with an OEM part and the problem still occurs with our vehicle. It is a big enough of a parts failure/equipment failure that most of my mechanic buddies I've talked to knew exactly what I was talking about and said I replaced these two parts and the problem was solved. May not be enough for a recall but a TSB really should be issued because I've found a lot of information online that a lot of people are having this same issue. Between this website's complaint section and other Chevy/GM forums, I'm estimating 5000-10000 people have had similar issues with the stabilitrak being disabled somehow while driving. Manufacturers need to be held accountable for parts failures like this, as when recalls do finally happen, it is next to impossible to get the vehicle in and repaired in a timely matter (Takata air bag inflator issue is a great example, our local dealer cannot give me an estimated date they can get the vehicle in for repairs because its a mass parts recall and the replacement parts are unavailable) Incident has happened over a dozen times in the past 6 months but the additional details will not let me select multiple dates

Without warning on several occasions the the gps/radio screen, door locks, lights, gauges, etc start cycling and going crazy and power to the vehicle goes on and off. While the electrical storm is happening I can press the gas pedal which only causes the car to sputter and lurch forward. It has occurred suddenly while pulling into traffic or while traveling on the highway at normal speeds. I have contacted GM and was told there are no recalls open. After researching on my own there are several forums with countless complaints of the same nature. To state the obvious...this is dangerous and the fact that GM is aware and continues to ignore the problem is highly unethical and unsettling.

The contact owns a 2013 Chevrolet Tahoe. The contact stated that while driving at various speeds, the vehicle would stall with several unknown warning lights flashing on the instrument panel. The contact also stated that other electrical features such as the exterior lighting and the power locks would activate on and off independently during the failure. The contact had taken the vehicle to the dealer and was informed that since there were no active warning lights displayed on the instrument panel, a diagnostic test could not be performed. The failure persisted and the contact discovered NHTSA Campaign Number: 14V614000 (Electrical System) which she linked to the failure. The contact took the vehicle back to the dealer and was informed that the VIN was not included in the recall. The manufacturer was not notified of the failure. The vehicle was not repaired. The failure mileage was approximately 120,000.

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.

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.
