2013 Mercedes-Benz E-Class E350 Sport 4dr Sedan (3.5L 6cyl 7A)
I leased a 2013 E350 sport sedan about 7 months ago.
When I picked up the car the door had a scratch in it.
Great, band new car, already repainted.
TThen the car developed a pronounced rattle at idle.
The dealer fixed it by adding felt tape along side the "fuel line". (!?)
6 months later I test drove a C300 and noticed it had
less exhaust system noise/drone.
I took the E350 in and they compared it to other E350 sedans and agreed my exhaust system was make an unusually loud droning noise.
They contacted MB and were told that there were other complaints on this issue and that a "case" had been opened but there was no resolution yet.
I was told to check back in 6 months!?
Multimedia functions, very solid feel, very low road/tire noise.
Fix the exhaust noise.
Also the engine sounds as if it staining during acceleration, unlike the very smooth an effortless feel of a BMW engine.
