THE BRAKE PEDAL ON THIS VEHICLE GOES TO THE FLOOR WHEN BRAKING ON GRAVEL ROADS. IT RETURNS FUNCTIONING AFTER PUMPING THE PEDAL. THE DODGE DEALERSHIP IN LAKE HAVASU CITY, AZ HAS HAD THE VEHICLE TWICE FOR A WEEK OR TWO AND LAST WEEK TOLD US THAT THESE VEHICLES SHOULD NOT BE DRIVEN ON DIRT ROADS BECAUSE THE DUST GETS ON THE ABS SENSOR AND CAN CAUSE THIS PROBLEM. THIS CAR HAS BEEN DRIVEN ON THIS SAME ROAD FOR SEVERAL YEARS AND HAS JUST STARTED DOING THIS IN THE LAST YEAR. THE DODGE DEALERSHIP HAS NOT BEEN ABLE TO DUPLICATE THE PROBLEM, SO THEY ARE SAYING THERE IS NOTHING WRONG. I PAID THEM TO CHANGE THE MASTER CYLINDER ON THE FIRST VISIT TO THE DEALERSHIP BECAUSE I HAVE EXPERIENCED SIMILAR PROBLEMS CAUSED BY THE MASTER CYLINDER IN THE PAST. OF COURSE THIS WAS BEFORE ABS AND CARS BECOMING SO COMPLICATED THAT I CAN NO LONGER WORK ON THEM. CHANGING THE MASTER CYLINDER DID HAVE AN EFFECT ON THE PROBLEM, BUT IT DID NOT CURE IT. I BELIEVE THIS IS A POTENTIALLY DANGEROUS PROBLEM AND I AM CONCERNED THAT DODGE HAS NOT TAKEN THIS PROBLEM AS SERIOUSLY AS THEY SHOULD. THE FIRST CASE NUMBER THAT DODGE GAVE ME WAS 79023033. THEY WERE SUPPOSED TO SEND A TECHNICIAN TO THE DEALERSHIP TO HELP, BUT I DON'T KNOW IF THAT HAPPENED. THE SECOND CASE NUMBER IS 79309555. THEY SAID WE COULD TAKE IT TO OTHER DEALERSHIPS FOR A SECOND OPINION AT OUR EXPENSE WHICH OF COURSE WILL BE EXTREMELY EXPENSIVE. THANK YOU FOR ANY HELP YOU CAN GIVE.

THE ELECTRICAL SYSTEM ON THIS VEHICLE SHUTS THE VEHICLE DOWN WHEN THE BATTERY ISN"T STRONG ENOUGH TO SUPPORT THE COMPUTER. THIS HAPPENS WHILE DRIVING. CAUSING LOSS OF STEERING AND CONTROL OF THE VEHICLE. THE TRACTION CONTROL SHUTS OFF AND BECAUSE THE ENGINE SHUTS DOWN THE POWER STEERING IS GONE AND THE POWER BRAKES . THIS HAPPENED TO ME COMING AROUND A SHARP CORNER OF AN OFF RAMP. I LOST ALL CONTROL OF THE VEHICLE AND ALMOST WENT OFF THE ROAD. I CALLED THE SERVICE DEPT. OF MY DEALERSHIP AND THEY TOLD ME THIS IS COMMON WHEN THE BATTERY CHARGE ISN'T POWERFUL ENOUGH TO SUSTAIN THE COMPUTER. BUT THERE ARE NO WARNING SIGNALS OR ANYTHING WITHIN THE CAR TO TELL YOU THE BATTERY IS LOW. I DID A SYSTEM CHECK WHEN I PULLED OVER AND THE SYSTEM SAID "OK". I FEEL THIS IS A SERIOUS SAFETY ISSUE. SOME ONE CAN SERIOUSLY BE HURT OR KILLED.

ON MAY 30TH I WAS HEADING HOME AFTER A LOG DAYS WORK WHEN I NOTICED THAT THE BATTERY LIGHT HAD TURNED ON, THINKING IT WAS JUST THE BATTERY NEEDING TO BE RECHARGED I KEPT DRIVING. MINUTES AFTER THE CHECK ENGINE(MIL), BRAKE (PARKING BRAKE?), ABS, ESP BAS, TRACTION CONTROL LIGHTS CAME ON AND GUESS WHAT HAPPENS NEXT!? I LOSE MY ABILITY TO STEER AND BRAKE MY VEHICLE GOING 60 ON THE HIGHWAY! LUCKILY I LIVED 8MIN AWAY FROM MY PLACE AT THE TIME AND MANAGED TO GET TO MY HOME WITH NO POWER STEERING ON BRAKING ABILITY! SO I WENT TO AUTOZONE AND BOUGHT MYSELF A BATTERY BECAUSE IT WAS TESTED AS A BAD BATTERY IT WAS INSTALLED ON MY CAR & IT TURNED ON AS NORMAL, UNTIL I ACTUALLY DROVE MY CAR TO SCHOOL THE FOLLOWING MORNING, SET IT ON PARK & SMOKE STARTED COMING OUT OF MY ALTERNATOR. KNOWING HOW MUCH A ALTERNATOR FOR MY CAR COSTS I SAVED ENOUGH MONEY TO BUY A AFTERMARKET ALTERNATOR SO I WENT TO AUTOZONE TO BUY ONE AND THE GENTLEMEN TOLD ME THAT IT GIVES HIM THE OPTION TO ORDER ONE BUT WHEN HE DOES THEY DON'T HAVE ANY BECAUSE SINCE THE CAR IS NEW THE ONLY I COULD GET IS THE MANUFACTURED ALTERNATOR WHICH THEY SELL FOR $545 AND ARE ON BACK ORDER!? REALLY DODGE REALLY? IT TOOK ME A MONTH TO SET ASIDE MONEY FOR WHAT I THOUGHT I COULD BUY A ALTERNATOR AND COME TO FIND OUT YOU'RE THE ONLY ONES THAT SELL IT, SHAME ON YOU GUYS! I'M FATHER A HARD WORKER AND A STUDENT AT UTI AND YOU GUYS DON'T ALLOW ANYONE TO SELL YOUR ALTERNATORS. DOESN'T MAKE ANY SENSE BEING THAT YOU'RE ON BACK ORDER. THIS COULD'VE ENDED WAY WORSE WHEN I WAS ON THE HIGHWAY. IF YOU'RE READING THIS AND HAVE THE SAME PROBLEM, PLEASE SUBMIT A COMPLAINT AS THEY WILL EVENTUALLY SEE A TREND ABOUT THIS AND HOPEFULLY RECALL THESE BAD ALTERNATORS THAT DENSO MANUFACTURES. *TR

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.

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.
