252,867 of C-Class sedans from Mercedes have been recalled in the US because apparently some electrical issue has left the tail lights vulnerable to some default; they can either get dim or completely fail altogether. This reason for recalling such a large number of cars has been stated in the report which has been forwarded to the US safety regulators. The company is currently recalling the C300, C350 and C63 models of sedans which belong to the years 2008 through 2011.
This has been reported to the US safety authorities for obvious reasons; the tail light represents an important element in driving safety and the dimming or absence of these can lead to higher possibilities of road accidents as stated in the documents filed with the U.S. National Highway Traffic Safety Administration. Back in 2009, Mercedes received five such reports which were related to the failure of tail lights due to electrical connection loss. At that time, the cause of this had not been known and the reports were made subject to further study.
It was till last year that NHTSA brought back this issue and Mercedes replied with some information in October. Further information was requested from Mercedes last month and as a result Mercedes decided to recall these cars. As a solution, dealers are going to replace the light bulb holders as well as any corroded connectors. Parts are not so readily available at this moment so owners of these c are going to be sent an interim notification in June and a second letter will be sent when the parts are available.
