2013 Mercedes-Benz SLK250

The defect

Mercedes-Benz USA, LLC. (MBUSA) is recalling certain 2013-2017 vehicles due to a software fault that may cause the date and time for the emergency call system (eCall) to differ from the actual date and time, potentially relaying an inaccurate vehicle location. For a full list of the affected models visit: https://static.nhtsa.gov/odi/rcl/2019/RMISC-19V787-4620.pdf

The risk

An inaccurate vehicle location may delay emergency responders, increasing the risk of injury.

The remedy

MBUSA has initiated an Over the Air (OTA) remote update. MBUSA will also notify owners, and dealers will check software for a successful OTA or update the communication module software as needed, free of charge. The recall began December 23, 2019. Owners may contact MBUSA customer service at 1-800-367-6372. MBUSA's number for this recall is 2019120008.

The defect

Mercedes-Benz (Mercedes) is recalling certain model year 2013 SLK250 and SLK350 vehicles manufactured October 9, 2012, through November 20, 2012. These vehicles are equipped with an occupant classification system (OCS) that may not correctly differentiate between a child seat or a very light person being in the front passenger seat.

The risk

If the OCS incorrectly classifies a very light person as being a child seat, in the event of a crash necessitating airbag deployment, the system would deactivate the passenger airbag, increasing the 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 July 26, 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.

While passing a vehicle on a two lane road, my vehicle lost power and went into limp mode nearly causing a head on accident. The check engine light came on and i immediately went to O'Reilly's Auto parts store and had their OBD scanner read the code. AP0002 code was read. I immediately returned home and the check engine light automatically cleared. I scanned the OBD again and found code P0002 and a second code P000277 that was listed as stored and current Both codes refer to an issue with the high pressure fuel pump. I just recently purchased this vehicle with 35170 miles. I had the OBD scanned prior to purchase, there were no codes at that time so we purchased the vehicle. We've since put …

The contact owns a 2013 Mercedes-Benz SLK250. The contact stated while driving approximately 65 MPH, the convertible roof cover started to pull away from the cross-support members connected to the windshield. The contact stated that the separation failure of the roof top become more pronounced, and water there was water leaking into the vehicle, causing an electrical short circuit of the convertible roof controls and the courtesy lights located in the overhead panel. The contact had taken the vehicle to a local dealer, where it was diagnosed and determined that the convertible top needed to be replaced; however, the convertible roof top was no longer manufactured. The vehicle had not been …

SIGNIFICANT TIMING CHAIN RATTLE WHILE DRIVING IN THE 2200-2900 RPM RANGE. ENGINE HAS LESS THAN 70K MILES AND IT SEEMS THAT THE CHAIN HAS STRETCHED OR IS TENSIONER IS FAILING. MERCEDES CLAIMS THEY CANNOT FIND SOURCE OF RATTLE AND REFUSES TO FIX IT, BUT ONLINE FORUMS INDICATE THIS IS A KNOWN ISSUE FOR THIS ENGINE. I FEEL THEY ARE DEFERRING THE ISSUE UNTIL THE WARRANTY EXPIRES. I FEEL EARLY FAILURE OF THE TIMING CHAIN OR RELATED PARTS IS IMMINENT.
