MY 2014 MERCEDES GLK 250 WITH 16,705 MILES, ON 11/03/2015 EXPERIENCED THE ENGINE WARNING DISPLAY STATING TO ADD BLUE. I DID THIS BUT THE WARNING DID NOT REMOVE BUT STATED I HAD 10 STARTS REMAINING. I WAS 700 MILES FROM HOME SO RETURNED CONSERVING MY REMAINING STARTS. FOUND MULTIPLE PROBLEMS WITH THE BLUE TECH EMISSIONS SYSTEM INCLUDING DEF INJECTOR NOZZLE FAILING TO SPRAY. ALL COVERED BY WARRANTY. ON 06/15/2019 WITH 58,129 MILES, THE ENGINE WARNING LIGHT AGAIN CAME ON TO ADD BLUE. I CHECKED BLUETEC LEVEL TO BE NEARLY FULL. THE WARNING STATED I HAD EIGHT REMAINING STARTS. BEING 700 MILES FROM HOME, I RETURNED. HAVING THREE REMAINING STARTS.I TOOK THE VEHICLE IN FOR IMMEDIATE REPAIR. FOUND NOX SENSOR 2 FAULTY AND WAS REPLACED. ON 6/28/2019 WITH 58,126 MILES, THE ADD BLUE WARNING AGAIN APPEARED. THE BLUEDEF WARNING ONLY 10 STARTS REMAINS. THE NEAREST MERECEDES DEALER WAS IN DENVER BEING 173 MILES AWAY. I TOOK IT THERE WHERE THEY REPLACED DEF MODULE, THE PREHEATER AND TANK TEMP AMOUNG OTHER FAULTS. ON 7/15/2019, WITH APPROX. 58,300 MILES, THE SAME WARNING APPEARED. RETURNED TO THE SAME DENVER DEALER WHO THEN REPLACED THE NOX SENSORS IN THE EMISSION SYSTEM. I WAS INFORMED THAT THE FREQUENCY OF REPAIR FOR THIS MODEL IS VERY HIGH AND EXPENSIVE (MY LAST TOTALED $5,000). THIS VEHICLE IS TOTALLY UNRELIABLE AND SHOULD HAVE BEEN RECALLED. BECAUSE OF THE EMMISION SYSTEM UTILIZED, NUMBEROUS OTHER PROBLEMS OCCUR SUCH AS THE COMPLETE WINDSHIELD WASHER SYSTEM WAS REPLACEDDUE TO THE EXTREME HEAT CREATED BY THE SYSTEM. SAME WITH OIL LEAKS, ETC.. MERCEDES COULD HAVE AT A MINIMUM EXTENDED THEIR SKIMPY WARRANTY OF 50,000 MILES BUT THEY REFUSE TO ACKNOWLEDGE ANY FAULT CLAIMING "THE BEST OR NOTHING"!

BLUE TEC SYSTEM FOR DIESEL FUEL EMISSIONS IN MY 2014 MERCEDES BENZ GLK250 MODEL IS INHERENTLY FLAWED WITH REPEATED FAILURES THAT CAUSE THE CAR TO "GO LIMP" (UNABLE TO START AFTER 10 OR LESS STARTS WHEN THERE IS A FAILURE IN THE BLUE TEC SYSTEM.) AS A RESULT, THE CAR IS NOT ONLY UNRELIABLE, IT IS UNSAFE SHOULD THE CAR "GO LIMP" WHEN NEEDED FOR EMERGENCY OR ON A ROAD TRIP OR UNABLE TO DRIVE OUT OF AN UNSAFE AREA, ETC., SINCE ONLY A MERCEDES BENZ DEALER CAN RE-SET THE SYSTEM AFTER REPAIRS SO THAT THE CAR WILL START AGAIN. TO DATE (5/16/19) MY 2014 GLK250 HAS 28,388 MILES AND HAS BEEN RETURNED TO THE DEALER 6 TIMES (FIRST TIME, DEC. 6, 2014 AND 5 MORE TIMES SINCE) DUE TO THE ELECTRONIC WARNING MESSAGE "10 REMAINING STARTS/ADD BLUE" WHICH HAS ALWAYS TURNED OUT TO BE AN ELECTRONIC FAILURE IN THE BLUE TEC SYSTEM. THE MESSAGE MAY APPEAR WHEN THE CAR IS PARKED AND THE IGNITION IS TURNED ON OR WHILE DRIVING. SOMETIMES, THE CHECK ENGINE LIGHT MAY FIRST APPEAR FOLLOWED BY THE "REMAINING STARTS" MESSAGE A FEW DAYS LATER. THERE IS NO LOGIC OR SET SEQUENCE. AND WHEN IT APPEARS, THERE IS NO ALTERNATIVE BUT TO IMMEDIATELY GO TO THE DEALER FOR REPAIRS AND TO RE-SET THE COMPUTER SO THE COUNT DOWN STOPS AND THE CAR CAN BE STARTED. THE REASON THIS IS NOT A WIDELY KNOWN PROBLEM IS THAT THERE WERE NOT MANY GLK 250 BLUE TEC CARS SOLD IN THE U.S. AND MERCEDES BENZ NO LONGER BUILDS THIS MODEL AND HAS STOPPED OFFERING DIESEL PASSENGER CARS IN THE U.S. FOR MORE INFORMATION ON COMPLAINTS, SEE LINK.: HTTPS://MBWORLD.ORG/FORUMS/GLK-CLASS-X204/517220-2014-GLK250-CONTINUED-ISSUES-BEWARE.HTML NOTE: THE DATE BELOW IS THE START DATE OF THE BLUE TEC PROBLEM FOR MY CAR AND THE MILAGE BELOW WAS FOR THE FIRST TIME THE CAR WAS TAKEN TO THE DEALER TO FIX THE PROBLEM FOLLOWED BY 5 MORE TIMES AFTERWARDS SINCE 12/6/14

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.
