2012 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.

The contact owns a 2012 Chevrolet Tahoe. The contact stated that the rear driver’s side and passenger’s side doors failed to open manually or while using the power door lock button. The contact was concerned because rear-seat occupants could be trapped and injured during a crash or a vehicle fire. The dealer and an independent mechanic were contacted and provided an estimate for the repair. The vehicle was not diagnosed or repaired. The manufacturer was not contacted. The failure mileage was approximately 85,000.

The AC in the front stopped working on and off but the AC in the back continues to work that's one warning a situation. The second is the oil light constantly shows low oil even when you get an oil change. The park tire pressure always moves back and forth to 40% to all the way down to 30.

The contact owns a 2012 Chevrolet Tahoe. The contact stated that while driving at an undisclosed speed, the vehicle lost motive power with the check engine warning light illuminated. The vehicle was towed to an independent mechanic where it was diagnosed that the engine had failed and needed to be replaced. The vehicle was not repaired. The vehicle was towed to the dealer, where the same diagnostic information was provided. The contact was informed that the engine needed to be replaced. The vehicle was repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 81,000.

The contact owns a 2012 Chevrolet Tahoe. The contact stated while driving at approximately 30 MPH, the brake pedal was depressed to slow for a traffic light and the vehicle jerked while shifting into low gear. The contact stated that while depressing the accelerator pedal when the traffic light had changed, the vehicle hesitated before responding and was jerking and shuddering while changing gear and accelerating. There was no warning light illuminated. The contact stated that the failure became a recurring failure. The contact had taken the vehicle to a local dealer, where it was diagnosed and determined that the transmission needed to be replaced. The vehicle was not repaired. The manufacturer was informed of the failure and had referred the contact the NHTSA Hotline. The failure mileage was approximately 86,000.

My 2012 Chevy Tahoe Dashboard is completely cracked up. This seems to be a very common issue as I read online. I am very concerned about the Safety with the Dashboard being cracked in multiple areas. What do I need to do to get Chevy to replace this at no cost to me?

I was rear ended while stopped by another truck that was going 60+ mph. None of the airbags in my 2012 Chevy Tahoe deployed. The backside of the driver and passenger seats fell off - unsure if that is airbag related but nothing deployed. My car was totaled my insurance.

While barely moving, (about 2 mph), in a parking lot & preparing to make a sharp left turn, knuckle of driver's side wheel assembly suddenly broke, causing the wheel assembly to collapse, wheel top tilted inward and bottom tilted outward, causing major damage to upper and lower control arms, tie rod and significant body damage to two body parts at the wheel opening. Mechanic reported that there had been very excessive ‘play’ before the collapse At 86,000 miles, this is a very low-mileage for this degree of wear and complete failure, on a full-size, PPV SUV, with many heavy-duty features, designed to tolerate high stress usage. FORTUATELY, the car was barely rolling. If this had happened 5 minutes later, I would have been driving 65 mph and this would have caused a catastrophic wreck, could have involved several other cars, and could have injured or even killed many people. I am now very concerned about the condition of the knuckle on the passenger side. It could be developing microscopic cracks that would only be observable with X-ray. ESPECIALLY with this defect being on a very popular police model, Highway Patrol PPV vehicle, more failures will endanger many people.
