metallic rattle at low speeds..

Lately I've been noticing that at low speed, light acceleration, I can hear this metallic rattle coming from the front of the car...it's not so much of a rattle, but a metallic "zing", haha. I really don't know how to explain it. It's not pinging, but if I turn my A/C and radio off, I can hear it from the inside with all windows closed. It also seems like my engine is producing a slight crunchy vibration through the gas pedal thats become more apparent when accelerating, or even coasting. Any suggestions? Also, sorry for my poor choice of adjectives and verbs, they were the best that I could come up with.

That is a tough one to diagnose without being in the car. It doesn't sound good as you can hear it and feel it. I would take it to the shop ASAP.

I believe I may have recently started experiencing some of the same issues on my 350. It's a slight noise at low speeds and usually when I'm turning left or just have turned left.

Have you had yours checked out yet?

While I was waiting to pick up my car on Friday, I was talking to a woman who had her C300 4Matic in for the same thing. They had to replace something in both front struts to cure the "ping" noise. But her description was almost the same as yours.

Mines a low RPM metallic rattle that comes from what sounds like underneath the front of the car. It's not pinging, but I can hear the sound reflect off garages etc. You'd have to hear it to know I guess.

I read your post and thought I might be about to experience a "duh" moment, but that wasn't it.

It isn't a rattle so much as a whine-type noise...similar to the noise you hear when say a drive belt starts to go bad.

Whatever it is it is coming from the front left of my car. Front struts could be the problem. I've got a few other issues to get checked out so I'll add it to the list and report back what becomes of it.

Sorry to revive a 5 year old thread. But I was wondering if you ever figured out what the issue was? I have the same problem.
