VEHICLE STOPPING AND SHUTTING OFF COMPLETELY WHILE DRIVING (IN MOTION) EACH AND EVERY TIME ON FOUR DIFFERENT OCCASIONS. FIRST TIME IT SHUT OFF, DEALERSHIP SAID IT WAS DUE TO OIL CHANGE.SECOND TIME DEALERSHIP SAID A RECALL ON THE SHIFT GEAR IN WHICH I WASN'T NOTIFIED ABOUT THE RECALL. THIRD TIME IT SHUT OFF, DEALERSHIP SAYS ITS AN OIL LEAKAGE. FOURTH TIME IT STOPPED, DEALERSHIP SAYS IT NEEDS A NEW ENGINE. CHRYSLER REFUSES TO FIX IT. THE LAST TIME I TOOK IT TO THE DEALERSHIP, CHRYSLER RESPONSE WAS TAKE IT HOME AND DRIVE IT AGAIN AND BRING IT BACK IF IT SHUTS OFF AND MAYBE THEN WE WILL FIX IT. I HAD TO HAVE IT TOWED IN THE LAST TIME DUE TO IT NOT STARTING AND SMOKING IN THE TAIL PIPE. ON TWO OCCASIONS, THE RADIO CUT OFF COMPLETELY, SCREEN JUST WENT BLACK. MY CAR IS NOW AT THE DEALERSHIP WAITING ON APPROVAL FROM CHRYSLER TO GET FIXED. THIS JEEP IS VERY UNSAFE, DANGEROUS,AND A SAFETY HAZARD FOR MY SON AND I. IT HAS PUT ME AND MY SONS LIFE IN DANGER ON FOUR DIFFERENT OCCASIONS. I AM TERRIFIED TO DRIVE THIS VEHICLE EVEN IF THEY CAN FIX IT BECAUSE ITS NOT A GUARANTEE THAT I WILL NOT HAVE THESE ISSUES AGAIN AND NEXT TIME IT COULD COST US OUR LIVES.

THIS VEHICLE CONSISTENTLY IS 1 QUART LOW ON OIL DURING EACH OIL CHANGE, AND THERE IS NO OIL ON THE DIPSTICK, DESPITE THE FACT I GET MY OIL CHANGED PRIOR TO THE RECOMMENDED MILEAGE, AND LESS THAN EVERY 3 MONTHS. I AM USING SYNTHETIC OIL IN THE CAR. I HAVE TAKEN IT TO THE ORIGINAL DEALERSHIP, THEN AN OIL CHANGE SHOP TWICE, AND THEN ANOTHER DEALERSHIP TO LOOK AT THE ISSUE. THE LAST DEALERSHIP ADVISED ME THEY WOULD DO AN OIL CONSUMPTION TEST AND THAT I NEEDED TO CHECK MY OIL DIPSTICK FREQUENTLY AS THE ENGINE WILL SHUT OFF IF THE OIL GETS TOO LOW. NO INDICATOR LIGHT HAS EVER DISPLAYED INDICATING AN ISSUE WITH THE LOW OIL OR OIL PRESSURE. MANY TIMES THE DISPLAY SHOWS I HAVE 40% OR MORE OIL LIFE LEFT, DESPITE THE FACT THE CAR WILL BE 1 QUART LOW ON OIL, WITH NO OIL ON THE DIPSTICK. THE CAR HAS 26500 MILES ON IT. THE FIRST TIME THE ISSUE WAS NOTED WAS WHEN MY CAR DID SHUT OFF IN DRIVE, AND I PULLED IT INTO AN OIL CHANGE PLACE WHO ADVISED ME THERE WAS NOT ENOUGH OIL IN THE ENGINE. THE CAR HAD JUST HIT THE MILEAGE MARK TO BE CHANGED. THIS OCCURRED IN THE FALL OF 2018.
THE "SERVICE SHIFTER" LIGHT WILL TURN ON. IT HAS HAPPENED TWICE, THE FIRST TIME AT LESS THAN TEN MILES PER HOUR IN A PARKING LOT AND THE SECOND TIME ON THE INTERSTATE GOING 70 MPH.

THE "SERVICE SHIFTER" LIGHT WILL TURN ON. IT HAS HAPPENED TWICE, THE FIRST TIME AT LESS THAN TEN MILES PER HOUR IN A PARKING LOT AND THE SECOND TIME ON THE INTERSTATE GOING 70 MPH. WHEN THE SERVICE SHIFTER LIGHT TURNS ON, IT ILLUMINATES THE PRND LIGHTS ON THE SHIFTER TO ALL RED. SINCE THEY ARE ALL RED, YOU CANNOT TELL IF YOU ARE IN PARK COMPLETELY. THERE IS 26,650 MILES ON THE VEHICLE. IT IS CURRENTLY GETTING SERVICED, THE DEALERSHIP I BOUGHT IT FROM SAID IT ONLY NEEDED FLASHED WITH THE COMPUTER, HOWEVER THE DEALERSHIP THAT IS CLOSEST TO MY HOME (AND THE ONE WHO IS CURRENTLY REPLACING THE GEAR SHIFTER) TOLD ME THE GEAR SHIFTER HAD TO BE REPLACED AND FLASHING WITH THE COMPUTER WOULD NOT FIX THE ISSUE, AS THIS WAS A FREQUENT ISSUE THEY HAVE SEEN. IF THERE IS A FREQUENT ISSUE WITH THE SHIFTER IN THESE VEHICLES, THEY NEED TO BE RECALLED. THIS IS VERY DANGEROUS AND SCARY TO NOT HAVE ANY WAY OF KNOWING IF YOU ARE IN PARK, REVERSE, NEUTRAL OR DRIVE.
CAR CAUGHT FIRE. MANUFACTURER DID NOT INVESTIGATE. DEALERSHIP WHERE IT WAS TOWED TAMPERED WITH EVIDENCE
MY 2018 JEEP CHEROKEE LATITUDE STALLS WHILE IN MOTION. SO FAR IT HAS ONLY HAPPENED ON NEIGHBORHOOD STREETS. I HAVE 36,500 MILES ON IT. *DT CONSUMER TOOK VEHICLE TO THE DEALERSHIP ON APRIL 27TH,2019 FOR OIL CHANGE, THEY DID NOT MENTION LOW OIL BUT DID SAY MAY HAVE LOW ON COOLANT BUT WASN'T POSITIVE.*JB

1EA21002 · 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.

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.
