Investigation of Instrument Cluster Failure

Subject: Instrument cluster failure
Components covered:
  • Interior lighting
Investigations Summary: This investigation was opened on Nov. 10, 2005. It was closed on Feb. 8, 2006. Note: this investigation has resulted in a vehicle safety recall.
The office of defects investigation (odi) opened this investigation based on seven reports indicating that the instrument clusters in model year (my) 2000-2001 mercedes-benz s class vehicles failed in that consumers were unable to read any of the gauges while operating their vehicles at any speed during the day or night. In its 573 report to NHTSA dated February 1, 2006, mercedes-benz USA, LLC (mercedes-benz)states that there are three instrument cluster failure modes that would result in undesirable operation. These three failure modes are specific to certain dates of production (see below) for the subject vehicle, and mercedes-benz is recalling those vehicles within those dates. Specific information regarding the failure modes is described in mercedes-benz's report (see NHTSA recall 06v028). Three of the odi complaints submitted to mercedes-benz involve vehicles that were produced before the dates of production of vehicles affected by the three failure modes. Based on review of those three complaints, mercedes-benz was unable to identify a relation of those three to the defects identified in the recalled vehicles. All of the mercedes-benz complaints with vins identified were within the recall population (only 2 vehicle vins were not available to positively identify vehicle build date). The recall population will include 36,911 s class and cl class mercedes-benz vehicles built in the production dates ranging from June 2000 through November 2000, January 2002 through April 2002, and may 2004 through September 2004. These dates of production cover vehicles from the 2000-2002 my and the 2004-2005 my. To correct the condition, mercedes-benz will replace all affected instrument clusters with improved ones that are not subject to the failure modes. Mercedes-benz will begin owner notification during the 1st quarter of 2006.
