Squeaks when I tap gas pedal??
My car (2008-under 15 k miles) recently started making a squeaking sound. At first I thought it might be the brakes as it's almost a 'squealing' but after testing and driving a bit to see where it was coming from, I found that as I tapped the gas pedal lightly in traffic it squeaks each time. Each tap on the accelerator made a squeaking sound. (I also had the a'c on that day and been driving most of the day.) It frightened me so I didn't drive much yesterday and brought it to the dealer this morning. They just called and said they can't find anything-please help! I'm in sales and drive most of the day, usually city driving, sometimes not in the best neighborhoods and am very nervous about driving the car-is it dangerous?-it doesn't sound good to me!? Any ideas on what it might be? They were great at the dealership and want me to come in Monday and take it out with the mechanic to try to replicate the sound. thanks!!!

C300 Squeeky Gas Peddle
I have a 2011 C300 4Matic with about 20K on it, when I tap the gas peddle it squeaks. I thought it might have been the shoes I was wearing but it happens no matter the temp, shoes or driving condition and only when i am tapping it. I live in Chicago so its a lot of stop and go...slow traffic and its consistent. It is driving me crazy!!!! I have not taken the car in yet for this issue as I don't beleive its anything to be concerned of, just more of a nuisance. Has anyone experienced this? Was there a fix if you took it to MB? Thanks!

u sure its from the pedal and not anything else? my 2012 c250 makes a squealing sound when at low speed...it came from my left rear wheel well. and MB says its something with the e-brake not disengaging. but ive never once used my e-brake. my car has been in the shop 7 times now and its still in the shop now going into its 4th week.
my suggestion is to see exactly where the sound it coming from. have someone stand outside on both sides to see if its coming from outside of the car.
record the sound with your phone or camera. contact your dealer (hopefully your warranty is still good). and have them fix it. good luck

Squeaks
I don't know why the long treatise on belt squeals since the first post clearly said it is heard when the gas pedal is moved slightly.

They replaced the pedal assembly itself. The C350 gas pedal is a "fly by wire" meaning there are no rods or cables as such. Just wiring attached to the pedal itself--like a switch. My dealership told me there was no way to stop the noise from the pedal so they just replaced it.

I have this same issue, except it is definitely temperature related - it only happens at what seems like temperatures below 40F. It is a clicking/squeaking noise that seems to be coming from one of my passenger wheel wells. It only begins after driving for about 2 minutes after starting the car. Anytime I park for a few minutes and start back up, the noise goes away again for that same period of time.
I really can't pin-point it. Because it's temperature, I'm thinking it has to be a fluid of some sort, but it doesn't go away as I drive, the fluids should be heating up.
Anyone have any other ideas????

The only problem with the pedal idea is that when I put the car in park and rev the engine, there is no noise that responds to the pedal. It will occasionally make the noise when I am in park and not touching anything.
The noise is also more pronounced when going up hills, almost as if it is directly related to engine output.

Sorry, got no solution right now but same problem on mine, 2008 with 41K miles and it is cold outside...
I wonder if spraying a little WD40 around the area might help? Sure sounds like a spring needs a little lubricant

Mine just started doing this when it's cold. Seems to be the plastic parts squeaking when they move. I think it just needs to be lubricated. Going to do that next time I have the chance. You could try something like WD-40, but the best option is going to be a dry silicone spray lubricant. Use it very precisely so it doesn't end up on the carpet / pedals, otherwise it can get dangerous!!

Same here, 2008 with 42K miles. Very possible it is only cold related, sprayed lubricant with nothing to loose but that did exactly that...nothing. It is not that loud and does not happen all the time. My latest fix is to turn up the radio and wait for summer

Me too. Sprayed it with WD-40 (didn't have anything better around) and it did nothing. Maybe I didn't use enough, but I don't want it pooling in the rheostat and throwing an error either. I'm too lazy to drive all the way over to the dealer for such a simple thing. It has become quieter and more rare, even in this cold snap.
