What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2005 Mercedes-Benz AMG C55, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

From owner reports, verbatim
VEHICLE EXHIBITING SAME CHARACTERISTICS OF FUEL LEAK FROM GAS TANK AS OTHER VEHICLE MODELS INVOLVED IN NHTSA INVESTIGATION EA13-003. STRONG FUEL ODOR ORIGINATING FROM LEFT REAR SECTION OF THE VEHICLE BEHIND LEFT REAR WHEEL AFTER FILL-UP. ONLY OCCURS AFTER FILL-UP WITH FULL TANK OF GAS, I ONLY NOTICE WHEN STATIONARY BECAUSE I AM OUTSIDE OF THE VEHICLE. THE NHTSA INVESTIGATION EA13-003 NEEDS TO BE EXPANDED TO INCLUDE MY MODEL VEHICLE, C55 AMG. ALSO, PLEASE SEE THIS MBWORLD.COM THREAD: HTTPS://MBWORLD.ORG/FORUMS/C32-AMG-C55-AMG-W203/712997-C55-SMELLS-LIKE-GAS-AFTER-I-FILL-UP.HTML

From owner reports, verbatim
I AM VERY CONCERNED THAT THE AIR BAG RELEASE MECHANISM; OF MY CAR A 2005 MERCEDES BENZ C55 AMG, IS DEFECTIVE. I WAS INVOLVED IN 2 ACCIDENTS, 1ST A RIGHT FRONTAL WITH SEVERE DAMAGE NEEDING $26,000 IN REPAIRS, AND THE 2ND A LEFT FRONTAL THAT CAUSED SO MUCH DAMAGE THAT MY INSURER MAY TOTAL THE VEHICLE. THE 2ND ACCIDENT CAUSED MULTIPLE FRACTURES IN MY NECK VERTEBRAE AND COULD HAVE BEEN FATAL OR LEFT ME QUADRIPLEGIC BUT DUE TO MULTIPLE NEUROSURGERIES BY THE EXPERT IN THE FIELD, I SURVIVED. IN NEITHER ACCIDENT DID THE AIR BAGS DEPLOY AND I AM STRONGLY CONCERNED THAT THE RELEASE MECHANISM IS DEFECTIVE. THE VEHICLE IS STILL AT THE REPAIR YARD AWAITING A DECISION TO REPAIR OR SALVAGE(NO WORK HAS BEEN DONE YET) SINCE THE 2ND ACCIDENT. *TR

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
