Summary

The Office of Defects Investigation (ODI) opened this investigation based on 20 consumer reports.All of the vehicles were E55 AMG models and the complainants alleged fuel leaks or a strong odor of gasoline both inside and outside of their vehicle, particularly after refueling.Some complainants alleged that the leaks may be related to a 2008 Mercedes Benz emission recall (Campaign No. 2008020001) on the fuel filter module. This recall pertained to model years 2003-2006 E and CLS AMG models only.These AMG models use a different fuel pump and fuel filter module than the non-AMG E-class, however, they share other fuel system components, including the fuel tank.Since opening the investigation ODI has received an additional 350 reports relevant to this investigation.Of those reports, 116 reports are on the E55 AMG model.The remaining 234 reports are on other E-class models (i.e., E320, E350, E500, E550 and E63) which are now included in the scope of EA13-003.The investigation has been upgraded to Engineering Analysis, EA13-003, for further study.The ODI reports cited above can be reviewed at www-odi.nhtsa.dot.gov/owners/SearchNHTSAID under the identification (ODI) numbers cited on the following page.

An NHTSA investigation looks into whether a safety defect exists. Opening one is not a finding. Outcomes can include a recall, closure without action, or further inquiry.
