• Desiccated air bag inflator rupture investigation # EA21002

  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.

• Front roof panel detachment investigation # PE21001

  On january 8, 2021, after ongoing review with mercedes benz, the national highway traffic safety administration (nhtsa) office of defects investigation (odi) opened pe21-001 to assess allegations of front roof panel detachments while driving at highway speeds in certain 2015 mercedes-benz (mercedes) c-class vehicles.The subject front roof panel is a stationary panel composed of polycarbonate and is attached to the vehicle via adhesive at the time of manufacture. The panel is found on subject vehicles equipped with panoramic sunroofs. Over time, the subject panels may exhibit cosmetic degradation leading to replacement of the panel, a procedure which entails: removal of the old panel and adhesive, site preparation, and installation of a replacement panel with new adhesive.The consumer complaints that prompted the opening of pe21-001 all described detachments of front roof panels that had been replaced after the vehicle was put into service.Mercedes internal investigation identified a broader scope of affected vehicles (2014-2020 cla, gla, c, s, glc, and gle class) and found the following potential service procedure- related causes of front roof panel detachments:- improper surface pretreatments such as the use of the wrong primer or cleaner or scoring of the surface; or - use of the incorrect adhesive.These conditions lead to a front roof panel bond that, even if sound at the time of repair, cannot maintain its strength over time and environmental exposure.Mercedes updated its service and parts ordering systems to reinforce the proper use of specified kits and procedures via webinars, shop foreman meetings, and explicit reference to the risks incurred by diverging from the repair procedures. Mercedes is also furnishing parts ordering assistance, and will hold dealerships accountable for improper repairs.Odis analysis of the ten complaints it has received from the public (voqs) and mbusas complaint data submitted in response to the information request letter for pe21-001 identified a total of 57 non-duplicative reports alleging incidents in which the front roof panel detached from the vehicle while in motion. Included within the 57 reports are incidents where consumers state the panel detached "...And flew off into traffic."on march 19, 2021, mercedes notified nhtsa that it would recall subject vehicles with front roof panels known to have been replaced after the original sale of the vehicle. In total, the recall (designated as recall 21v197) covers 15,099 vehicles that were ever registered in the united states. Based on recall 21v197 and the remedy implemented by mercedes, further investigation does not appear to be warranted at this time.Accordingly, this investigation is closed.The odi complaints cited above can be viewed at www.Nhtsa.Gov under the following odi identification numbers: 11376425, 11352686, 11351629, 11349158, 11341541, 11337594, 11324100, 11311591, 11222127, 11404183

My sister was driving across town and came across some uneven payment near a construction zone. She hit a small-medium sized pothole and it somehow triggered both the front and rear passenger airbags to deploy. There was no damage significant impact when it happened and no damage to the exterior of the car (tire, wheel, fender). It happened today (saturday) so it was taken to a local independent repair facility. Will know more monday. Parts available for inspection upon request, of course.

While driving the other day i opened the sunroof when it suddenly made a strange sound and stopped. When i tried to close it i noticed that the left side was raised but the right side was down. It made a whirring sound and moved a little but refused to close. When i got home and looked at it it looks like the windscreen has come loose and looks like it was pushed forward and broken by the linkage that makes the roof go up. It looks like the linkage is bending forward when i suspect it should bend backwards. This has been happening since i bought the car in 2016. Sometimes it opened and while driving i'm afraid it might blow out into the high way. Causing an accident

When i bought my 2nd cla, i have noticed whenever i am driving & turn on the driver's heated seat, that it always burn my left leg, so i would always turn it off. This has been ongoing for quite some time. Fast forward to last night (2/20/21), i turned on my heated seats & i smelled something burning then it felt like my leg was on fire. This time the pain from the burning was worse than the other times. I immediately turned the heated seat off. I could not tell if the seat was giving off smoke because it was dark. I noticed the next day that there were a hole in that area on my drivers seat where the problem occurred. After seeing the hole in my seat, i thank god i turned the heated seat off because had i moved my leg from that burning area on my seat, ignored it & kept driving, i believe the seat would have created a fire! This most definitely screams a fire hazard, unsafe & should be deemed as a recall on all mercedes.

When accelerating hard to overtake, the engine lurches, and the car fails to accelerate further and slows down. The engine fault light then illuminates which switched off by itself after switching the engine off twice. It seems i am not the only person to have this problem as you can see in the comments to this video describing the problem and claiming the problem is a faulty high pressure fuel pump: https://youtu.Be/-sbr28zbofs this seemingly common issue is clearly dangerous as drivers lose the power when they are most depending on it and it seems to be occurring in cars that are not particularly old.

While driving out of a driveway, a car pulled near my car. At that time, the car was stationary. My wife heard the pre-collision warning. The the car completely shutoff or stalled. Turned off the car completely by turning the key. Then turned the car back on. Lucky there was no accident.

My son had to be cut out of the seat back because it was too tight and wrapped around him. The seatbelt strap was locked and would not extend out at all to loosen for extra length on the strap. The seatbelt strap was so tight my sons stomach was was cinched to the point where he couldn't breath. I'm not sure why the suspension on the strap was locked every other seatbelt had extended strap. This was a scary experience and could have severely hurt my son. This is unacceptable for the price i paid for this vehicle and not to mention my child's safety. I didn't take any pictures of the strap around my sons stomach because he was in pain and was frantically trying to get it loose and cut. I have pictures of where i had to cut the seatbelt. I also have a defect with my electrical which i causing my battery to die. The car will stay on completely without the key in the ignition or started. I have video of that as well. This is completely ridiculous for a luxury vehicle. My main concern is the safety of my passengers andy son simply unbuckling a seatbelt and getting strapped in because the suspension of the strap would not loosen and was locked is unacceptable. I tried everything to putting the car in drive pressing the brake to see it the strap would unlock and nothing worked. My son was in pain because of this defect o had to cut the seat belt strap off frantically. This is not okay!
