My vehicle randomly swerves back and forth when driving. It is very scary and could easily cause an accident and take my life. I’ve taken it to vigo dodge and had 3 different mechanics inspect my car over 5 hours and although they each drove my car and experienced what I’m referring to, they didn’t know what the problem is. I was told to just drive it til it got worse and then maybe they could find the problem. I’m scared to drive my car over 30 mph cause the random swerve could make me lose control or even swerve into oncoming traffic. I desperately need help and don’t know what to do.

I HAD THE SLIGHTEST CLUE WHAT THE SOUND WAS, OR WHERE IT WAS COMING FROM, SO OF COURSE I GOT ON YOUTUBE TO FIND A SOLUTION TO THE PROBLEM JUST TO MAKE SURE IT WAS NOT JUST ME, AND I WAS VERY GREATLY APPALLED TO THE NUMBER OF THOUSANDS OF PEOPLE THAT ARE OWNERS OF CHALLENGERS THAT HAD OR HAS THE SAME ISSUE AND NO ONE CAN FIGURE WHAT CAUSES THIS PROBLEM. IT HAPPENS WITHOUT WARNING AND IT'S HIGHLY UNSAFE. THE CLICKING SOUND EVEN OCCURS WHILE DRIVING. I DIDN'T KNOW RATHER THE CAR WAS ABOUT TO EXPLODE OR WHAT, BECAUSE THE CLICKING SOUND IS SO INTENSE. I POP MY TRUNK AND THERE'S CLICKING. I UNLOCK MY DOORS AND THERE'S CLICKING. ON SEPT. 21, 2018 WHEN THE SOUND BEGAN, OUT THE BLUE THERE WAS A CLICKING SOUND SO LOUD, I THOUGHT THE KEY WAS GOING TO FALL OUT THE IGNITION WHILE I WAS DRIVING WITH MY CHILD IN THE BACK SEAT, AND THIS HAS NOT ONLY HAPPENED TO ME, BUT THOUSANDS OTHER. THIS IS HIGHLY DANGEROUS WHILE DRIVING. PLEASE FIND AN ANSWER TO THIS PROBLEM. PLEASE AND THANK YOU.

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.
