Problem: Mercedes-Benz USA, LLC. (MBUSA) is recalling certain model year 2015 CLS 400 and CLS 400 4matic, 2012-2015 CLS 550 and CLS 550 4matic, 2012-2013 CLS 63, 2014 CLS 63, and 2014-2015 CLS 63P.

Risk: Reduced rear side marker illumination may prevent other drivers from seeing the vehicle, increasing the risk of a crash.

I have a 2012 Mercedes-Benz CLS63 that is leaking fuel from the rear driver side by the tire. You can smell fuel inside the cabin of the vehicle very strong. On the vin plate on my door it says in my vehicle is built on April 2011 which would qualify it for the recall from Mercedes. Per NHTSA.
