The 2008MERCEDES-BENZS63 carries 6 consumer safety complaints in NHTSA's Office of Defects Investigation database for this specific model-year cohort. Within that volume, owners reported 0 crashes, 0 fires, 0 injuries, and 0 fatalities. No NCAP 5-star crash-test rating is available for this model year in the federal database.
Component-level analysis is where model-year complaints become actionable: the top complaint category for the 2008 S63 is engine with 2 filings, followed by wheels (1) and electronic stability control (esc) (1). Concentration in one or two component groups is the classic signature of a systemic defect; a flat distribution usually reflects normal aging, warranty complaints, or isolated build-plant variability.
NHTSA currently has 15 investigation files overlapping the 2008 S63. Owners comparing this cohort against neighboring years should pair the counters above with the complaint-by-year trend on the parent model page — a spike in a single year often tracks to a platform refresh, a new transmission supplier, or an updated ECU calibration.

About 2 to 3 weeks ago I suddenly started smelling faint gas outside the vehicle on the driver side. Over 2 weeks it got stronger and finally I was able to smell it inside and immediately investigated. I discovered the fuel filter underneath the rear seat behind the driver was leaking and the foam under the seat was soaked in gasoline. I did not find my vehicle to be in recall for this safety issue. However, I did find recall 12V-557 for other models that have similar issues with a defective fuel filter. I believe my vehicle should be covered by this recall. I resolved this issue by visiting the dealership and after being told my vehicle was not under recall, I purchased the fuel filter myself from the parts department and replaced it. Included are 2 pictures. One showing crack in the filter that cause gasoline to spray against a cover and leak into the vehicle. And a second picture taken showing the fuel filter soaked in gasoline prior to its removal.

THE ENGINE HYRDO LOCKED AT 66000 MILES AND FAILED A PISTON ROD ACCORDING TO MERCEDES. CAR WAS MAINTAINED AND SHOWED NO ABNORMAL FUNCTIONALITY, JUST PRIOR TO INCIDENT AT HIGHWAY SPEED. ENGINE LOCKED UP. THIS APPEARS TO BE A COMMON PROBLEM WITH THIS CAR AND COULD BE ASSOCIATED WITH FAILED HEAD BOLT STUD.
