MY CHALLENGER IS MAKING A WIERD TICKING NOISE COMING FROM THE LEFT SIDE OF THE ENGINE. SEE RECALL BELOW CHRYSLER ANNOUNCED THIS MORNING THAT IT WILL BE EXTENDING THE WARRANTY ON 3.6-LITER PENTASTAR V-6 ENGINES IN CERTAIN 2011-2013 VEHICLES DUE TO CRACKED CYLINDER HEADS ON EARLY VERSIONS OF THE ENGINE ACCORDING TO AUTOMOTIVE NEWS, ROUGHLY 7500 ENGINES BUILT AS THE PENTASTAR V-6 WAS FIRST COMING OUT IN 2012, WERE FOUND TO BE SUSCEPTIBLE TO LEFT-CYLINDER HEAD CRACKS, POTENTIALLY RESULTING IN ENGINE FAILURE. CHRYSLER FIRST DISCOVERED THE ISSUE WHEN CUSTOMERS BEGAN COMPLAINING THAT THEIR VEHICLES WERE MAKING TICKING NOISES, STALLING, OR THAT THE INSTRUMENT PANEL WAS INEXPLICABLY DISPLAYING A CHECK ENGINE LIGHT. THE 3.6-LITER PENTASTAR V-6 COMES WITH A 5-YEAR/100,000 MILE WARRANTY, WHICH CHRYSLER WILL BE EXTENDING TO 10-YEARS/150,000 MILES ON THE LEFT-CYLINDER HEAD. THE CRACKED LEFT-CYLINDER HEAD ISSUE POTENTIALLY AFFECTS ABOUT 0.5-PERCENT OF VEHICLES EQUIPPED WITH THE 3.6-LITER V-6. CHRYSLER DETERMINED THAT SUBPAR FUEL ALONG WITH A NUMBER OF DRIVING CONDITIONS CONTRIBUTED TO THE ISSUE. A DESIGN MODIFICATION IN LATE 2012 HAS REPORTEDLY FIXED THE ISSUE IN NEWER VEHICLES. THE 3.6-LITER V-6, THE FIRST OF THE PENTASTAR FAMILY THAT NOW INCLUDES A 3.2-LITER VERSION, COMES STANDARD IN NUMEROUS CHRYSLER VEHICLES. THE 3.6-LITER PENTASTAR IS STANDARD ON THE: CHRYSLER 300, DODGE CHALLENGER, DODGE CHARGER, JEEP GRAND CHEROKEE, JEEP WRANGLER, RAM 1500, AND RAM PROMASTER. IT'S OPTIONAL ON BOTH THE PREVIOUS-GENERATION AND CURRENT CHRYSLER 200, AND DODGE AVENGER.

19V018000 · Air Bags:frontal:passenger Side:inflator Module

Jan 15, 2019

Chrysler (FCA US LLC) is recalling certain 2010 Dodge Ram 3500, Ram 4500/5500, 2010-2011 Dodge Dakota, 2010-2014 Dodge Challenger, 2010-2015 Dodge Challenger, Chrysler 300, and 2010-2016 Jeep Wrangler vehicles. Upon deployment of the driver's frontal air bag, excessive internal pressure may cause the inflator to explode.

Consequence & remedy

Consequence: In the event of a crash necessitating deployment of the passenger's frontal air bag, the inflator could explode with metal fragments striking the vehicle occupants potentially resulting in serious injury or death.

Remedy: Owners are advised not to drive their vehicle until the recall repair is complete. Chrysler will notify owners, and dealers will replace the passenger frontal air bag inflator, free of charge. The recall began February 4, 2019. Owners may contact Chrysler customer service at 1-800-853-1403. Chrysler's number for this recall is V01.

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.

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.
