Mercedes Benz Cls-class 2012

• Recall R/2017/124 [UK]: Faulty control unit may cause vehicle to perform outside specification
  Where a control unit coding was updated in a workshop between 3 december 2016 and 5 december 2016 the coding may not correspond to the specification and may trigger unplanned action in the vehicle. The safety and emissions systems may not react as design intent.
  recall the vehicles that are likely to be affected and update the software in the corresponding control units.

• Recall R/2015/041 [UK]: Fire may occur
  A seal between bonnet and engine compartment may when the bonnet is opened temporarily stick to the bonnet. If this happens the seal may detach form its fixing and can fall into the gap between engine and partition wall. It is then possible the seal can make contact with the exhaust and under certain conditions catch fire.
  on affected vehicles install additional clips to retain the seal.

• Recall R/2020/243 [UK]: Engine control unit software to be updated
  Improve the vehicle emissions via software updates.
  update the relevant control unit?S software and if necessary replace the nox sensors.

• Recall R/2019/256 [UK]: To achieve an improvement in the emissions via software updates
  Improve the vehicle emissions via software updates.
  update the diesel engine control unit software and add a supplementary booklet for the operator's manual

• Recall 2018724 [Canada]: Steering
  On certain vehicles originally sold or currently registered in areas of heavy road salt usage during winter months (quebec, new brunswick, nova scotia, prince edward island, and newfoundland & labrador), the bolts that attach the electric power steering assist motor to the steering gear housing may corrode and break. This could cause a loss of power steering assist. The resulting increase in steering effort could create the risk of a crash causing injury and/or damage to property. Correction: dealers will replace the mounting bolts and apply a corrosion protection coating to the gear housing and bolts. If the bolts bolt cannot be removed, a replacement steering gear will be installed.

• Recall 2015099 [Canada]: Lights and instruments
  Certain vehicles may not comply with the requirements of canada motor vehicle safety standard 108 - lighting system and retro reflective devices. Rear side markers may not have been programmed properly and may fail to meet the photometric performance requirements of the standard. This could reduce vehicle conspicuity, which could increase the risk of a crash causing injury and/or damage to property. Correction: dealers will reprogram the signal acquisition module.

• Recall 2012373 [Canada]: Structure
  On certain vehicles, the four bolts securing the secondary hood latch striker plate may have been insufficiently tightened and could loosen. If two or more bolts were to loosen, the secondary latch could become ineffective. If the engine hood was not closed properly, both primary hood locks were not latched and the driver were to ignore the hood open warning message in the instrument cluster, the ineffective secondary latch could allow the hood to open while driving, increasing the risk of a crash causing injury and/or property damage. Correction: dealers will inspect and retighten bolts if necessary.

• Desiccated air bag inflator rupture investigation as of 20210917

  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.

Tl* the contact owns a 2014 mercedes benz cls-550 (n/a). The contact stated that over a one-month period, all four factory tires failed and needed to be replaced because two of the four tires blew out. The vehicle was towed three times to the dealer. The dealer stated that the tires were low profile so that it would properly fit in the wheel well because of poor design. The manufacturer was made aware of the failure. The failure mileage was 13,000 to 14,000. The vin was not available.
