ON NOV 27, 2013, I WAS IN THE LOS ANGELES AREA ON HIGHWAY 14 TRAVELING AROUND 70 MPH ON THE HIGHWAY W/ MANY CARS AND MY SPEED DROPPED TO AROUND 50 MPH IN SPITE OF MY FOOT DOWNING THE ACCELERATOR TO THE FLOOR. I HAD TO TURN ON MY EMERGENCY LIGHTS AND MOVE OVER TO THE SLOW LANE FOR SAFETY. RETURNING HOME THAT SAME DAY ON THE SAME FREEWAY, THE CAR WOULD NOT ACCELERATE OR TRANSMISSION WOULD NOT DOWNSHIFT TO COMPENSATE FOR THE UPHILL ON THE FREEWAY IN SPITE OF STEPPING DOWN ON THE ACCELERATOR- AGAIN I HAD TO FLASH MY EMERGENCY LIGHTS ON AND MOVE TO THE SLOW LANE. THERE IS NO SENSOR LIGHT ON THE DASHBOARD FOR BOTH INCIDENTS. MY MECHANIC REPORTED IT WILL BE HARD TO DIAGNOSE THE TRANSMISSION PROBLEM SINCE THERE IS NO SENSOR LIGHT ON. ON NOV 29, 2013, I TRAVELED TO LAS VEGAS AND THE TRANSMISSION REPEATED THE DECELERATING INCIDENT AND FAILURE OF THE ACCELERATOR TO INCREASE ENGINE OR TRANSMISSION SPEED. THIS IS DANGEROUS. *TR

WHILE DRIVING THE VEHICLE, THE CHECK ENGINE LIGHT BEGAN TO FLASH RAPIDLY, THE ENGINE BEGAN TO RUN EXTREMELY ROUGH, HAD LITTLE POWER, AND WAS NO LONGER DRIVABLE. LUCKILY, THIS HAPPENED ON A SURFACE STREET AND NOT ON THE FREEWAY WHERE, I BELIEVE, IT COULD HAVE RESULTED IN HARM TO ME OR OTHER DRIVERS. THE PROBLEM WAS CAUSED BY A DEFECTIVE PLASTIC BUSHING IN THE INTAKE MANIFOLD WHICH BROKE AND WAS SUCKED INTO VALVE #4 WHICH THEN BURNED THE VALVE. AT THE TIME OF THE INCIDENT, THE VEHICLE HAD APPROXIMATELY 84,000 MILES ON IT. I WAS INFORMED BY THE MECHANIC WHO PERFORMED THE REPAIR ON MY VEHICLE THAT THEIR MB PARTS SUPPLIER STATED THAT MB IS AWARE OF THIS DEFECTIVE PLASTIC BUSHING. HOWEVER, THE PARTS SUPPLIER WAS APPARENTLY NOT PERSONALLY AWARE OF IT CAUSING THE TYPE OF EXTENSIVE DAMAGE I EXPERIENCED. MB REFUSES TO ACKNOWLEDGE, AT LEAST TO ME, THAT THEY ARE AWARE OF PAST INSTANCES INVOLVING THIS DEFECTIVE PLASTIC BUSHING OR TO EVEN CONSIDER THAT IT IS A PROBLEM THAT THEY SHOULD TAKE RESPONSIBILITY FOR BEFORE IT RESULTS IN HARM. I HOPE SOMEONE WILL TAKE THIS PROBLEM SERIOUSLY AND INVESTIGATE ITS POTENTIAL FOR HARM. *TR

I WAS DRIVING HOME AND NOTICED THAT WHEN I WOULD ACCELERATE AFTER COMING TO A STOP THE CAR WAS EXTREMELY SLUGGLISH. I WOULD HAVE TO ALMOST FLOOR THE GAS PEDAL IN ORDER FOR THE CAR TO BEGIN MOVING. I PULLED OVER AND THEN PUT THE CAR IN NEUTTRAL. THE JERKED VIOLENTLY AND SHIFTED VERY HARD AS I THEN TRIED TO PUT IT IN REVERSE AND THE INTO PARK. I TRIED TO PUT THE CAR BACK INTO DRIVE AND IT WOULD NOT ACCELERATE AT ALL. I HAD TO TURN THE CAR OFF AND THEN BACK ON AGAIN IN ORDER TO GET IT MOVING. THE GEARS CONTINUED TO SHIFT VIOLENTLY. HOWEVER, WHEN I FINALLY GOT MOVING AGAIN, THE CAR WOULD NOT GO OVER 35 MPH. THE CAR WAS INSPECTED AND AN ERROR CODE FOR THE INTERNAL SPEED SENSOR CAME UP, WHICH IS PART OF THE VALVE BODY FOR THE TRANSMISSION. MY CAR ONLY HAS 59,000 MILES ON IT. MERCEDES IS VERY AWARE OF THIS PROBLEM ON 2006-2007 C230 MODELS! IN FACT, THEY ARE HAVING A DISPUTE WITH THE MANUFACTURER OF THE VALVE BODY BECAUSE IT IS POOR QUALITY AND DEFECTIVE. I HAVE SEEN NUMEROUS OTHER COMPLAINTS RELATED TO THIS ISSUE. MY LOCAL MERCEDES DEALERSHIP QUOTED ME $2,400 TO REPAIR THIS DEFECTIVE PART. I WAS LUCKY IN THAT I WAS NOT DRIVING AT 60 MPH ON THE HIGHWAY WHEN THIS MALFUNCTION OCCURRED. THIS IS AN EXTREMELY DANGEROUS ISSUE AND A RECALL SHOULD BE ISSUED FOR THIS PART. *TR

THANK GOD THE RIDER WAS NOT BADLY HURT AND JUST HAD A FEW SCRAPES AND MY CAR WAS OKAY SO WE WENT OUR SEPARATE WAYS. THERE ARE SO MANY COMPLIANT ABOUT THIS SAME ISSUES ABOUT THE CAR NOT ACCELERATING AND GEARS GETTING STUCK IT IS BECOMING RIDICULOUS. I AM SURE THERE HAS BEEN CASES WHERE PEOPLE ARE SEVERELY INJURED OR PASSED AWAY BC OF THIS ISSUE BUT ONES THAT DIDN'T SURVIVED ARE NOT HERE TO FILE THEIR COMPLAINTS. THIS IS A SERIOUS MATTER AND A RECALL NEEDS TO BE DONE BEFORE BODIES ACTUALLY START PILING UP. MERCEDES.BENZ ARE KNOWN TO BE HIGH END LUXURY CARS AND THEY NEED TO ACTUALLY DRIVE LIKE ONES..

THE GEAR SHIFTER IS IN "D" DRIVE, GAUGE BETWEEN THE ODOMETER/TACHOMETER SHOWS "D" DRIVE AS WELL, HOWEVER THE CAR ACTS AS IF IT WAS IN NEUTRAL!!! SHIFTING INTO NEUTRAL, REVERSE, OR PARK, OR BACK INTO DRIVE - DOESN'T HELP! IT'S LIKE A TRANSMISSION IS STUCK IN NEUTRAL!!! ALSO, SHIFTING INTO D+/- TO ENGAGE MANUAL SHIFTING DOESN'T WORK! AND AS FAR AS YOU KEEP MOVING THE SHIFTER INTO REVERSE, NEUTRAL, MANUAL SHIFT, DRIVE - THE CAR ELECTRONIC GEAR DISPLAY ON THE DASHBOARD STILL SHOWS THAT THE CAR IS IN "D" DRIVE REGARDLESS OF WHAT POSITION YOU MOVE THE SHIFTER; AND THE CAR BEHAVES AS IF IT WAS IN NEUTRAL ALL THIS TIME (YOU ACCELERATE, RPMS GOES UP, REMOVE THE FOOT FROM THE PEDAL - ENGINE IDLES). THE ONLY WAY TO MAKE THE TRANSMISSION WORK AGAIN IS TO SHIFT IT INTO PARK "P", AND THEN TURN OFF THE ENGINE, AND THEN TURN THE ENGINE BACK ON, AND THEN TRANSMISSION WORKS WELL AGAIN FOR TENS OR HUNDREDS OF MILES BEFORE IT GETS "NEUTRALIZED" PARALYZED AGAIN. THIS ALSO HAPPENED TO ME WHILE DRIVING DOWN THE I-5 IN CALIFORNIA AROUND 70 MPH'S AND I HAD TO PULL TO THE SIDE OF THE ROAD AND TURN THE CAR OFF AND BACK ON, IN ORDER FOR IT TO START WORKING NORMAL. THAT IS DANGEROUS, WHAT IF I WOULDN'T HAVE BEEN ABLE TO STOP ON THE SIDE OF THE ROAD IT WOULD HAVE CAUSED AN ACCIDENT. *JB

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.

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.
