The defect

Mercedes-Benz USA, LLC. (MBUSA) is recalling certain model year 2013-2015 SL550, 2013-2014 SL63 AMG, 2014-2016 E350, 2014 E350 Cabriolet, E350 Coupe, 2014-2015 S550, 2015 E350 Bluetec, 2015-2016 E400, 2016 E550 Coupe, and Maybach S600 vehicles manufactured August 23, 2012, to August 14, 2015. The affected vehicles use an electric power steering system that may have improperly soldered contacts inside the control unit, potentially resulting in the power steering system deactivating while driving.

The risk

If the control unit pins lose connection, there would be a loss of electric power steering assist, increasing the risk of a crash. The increase in pin contact resistance can also increase the risk of a fire, even while the vehicle is parked and ignition is off.

The remedy

MBUSA will notify owners, and dealers will replace the electric power steering control unit, free of charge. The recall began October 13, 2017. Owners may contact MBUSA customer service at 1-800-367-6372.

The defect

Mercedes-Benz (Mercedes) is recalling certain model year 2013 SL63, SL550, and SL65 vehicles manufactured January 16, 2013, through April 30, 2013. The affected vehicles are equipped with an occupant classification system (OCS) that may not detect a very light person sitting in the front passenger seat.

The risk

If the OCS does not detect a very light person sitting in the seat, the passenger side air bag would be turned off. In the event of a crash necessitating side air bag deployment, the passenger would be at an increased risk of injury.

The remedy

Mercedes will notify owners, and dealers will replace the passenger side seat cushion including the OCS. The recall began on December 20, 2013. Owners may contact Mercedes at 1-201-573-0600.

the air bags

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.

I was driving on a country road when all of a sudden my car lost power all the warning lights camo on the dashboard. Smoke started billowing out from the back and front of the car. It turned off and I only coasted about a 100 feet. I could not safely pull off to the side of the road as the car had no power. Thankfully the road was not very busy and the tow truck collected the vehicle. Upon further inspection I saw a lot of oil on the road and the mechanics were able to confirm that the engine block was cracked and there were 2 large holes. Upon further research I was able to find a lot of similar cases with this specific M278 Mercedes engine and premature failures that happen because of bad …

The contact owns a 2013 Mercedes-Benz SL550. The contact stated while driving at an undisclosed speed, the vehicle lost power steering assist functionality. There was no warning light illuminated. The vehicle was taken to an independent mechanic, who determined that the steering rack needed to be replaced. The vehicle was not repaired. The contact related the failure to NHTSA Campaign Number: 16V899000 (Steering); however, the VIN was not included in the recall. The manufacturer was made aware of the failure but informed the contact that there was no recall associated with the VIN. The failure mileage was approximately 60,000.

The rear subframe experienced excessive levels of rust which caused the rear left side to suddenly collapse. After the collapse, the car would fish tail at low speeds (i.e., less than 15 miles per hour). I am thankful that the collapse did not happen when traveling at higher speeds such as an expressway, which would have certainly caused an accident. The Mercedes Benz dealer refused to cover the cost of the work to replace/repair the subframe. The dealer stated that they would cover the cost under an “extended warranty” if the car was manufactured for the US, but, as I found out, the car was made for Canada based on the VIN #. This is the case even though the subframe in this model had the …

Started the vehicle and used the gear selector to shift to Drive. Car did not go into gear. Towed to dealer. Dealer found faulty “ism module.” Apparently a very common issue with these cars. So common that the part is in an “indefinite back order.” The replacement part is also revised because Mercedes knows there was a manufacturer defect with the existing part. I am being charged more than $1600 on a part that the manufacturer has already acknowledged was faulty and created a replacement for it.

Cam sensor seals failed which leaked oil into the wire harness, O2 sensors, and ECM. This happens to be a common problem with M278 engine. The repair was $10,217 to fix this issue. The car would not pass emissions without this repair. Could oil into the electrical system pose a fire hazzard?
