2011 C300 engine noise, anyone else have this?
i have a 2011 C 300 luxury model. bought it in sept 2011. everything on it. car was fantastic, quiet, drove great. last month i got a noise (sounds like wind blowing through an open window) when i slowly accelerate or decelerate. constant sound. took into dealer. service manager took it out and heard the noise. they had it for 1 week and couldn't figure it out. just left it again for 2 weeks and they had corp tech's out and they also heard the noise. they have no answers for the problem. very dissatisfied with this car. now they say that all 300's will have this sound???????? drove 2012 loaner C300 w/ 4000 miles (mine has 4000) and didn't have noise. noise was not in car after i bought it. make any sense to the forum? has anyone else had a similar problem? the sound is similar to a wining sound and is very annoying. would appreciate hearing from anyone who has this model that may be experiencing or has experienced this noise. has anyone found an answer? thanks to all for the help
