Shake, Rattle and Roll!
It sounds like it is coming from inside the passenger compartment somewhere around the rear seats. Or possibly underneath the car below the rear seats.
I do have split/folding rear seats, but cannot isolate the problem. The MB dealer conveniently can't get the car to squeek when they drive it either.
It is driving me nuts!!!
Anyone on here have the same problem? Is it common with all E350's or just us unlucky few with the split/folding rear seats.
Thanks.
Unfortunately I have an outstanding rattling noise with the instrument cluster near the steering column and though I drove with the shop foreman and they claimed to have fixed it, it is still there so I have to take the car back in and do this all over again. I'm going to drive with the same foreman again so he hears the sound.
I know how frustrating and annoying a rattling sound can be and I hope you are able to get it fixed. These cars are generally very quiet so you hear ANYTHING inside the car that might rattle or make any noise. Blessing and a curse!
Sounds like you are still under the original bumper to bumper warranty so they should be able to fix this no matter what it takes. I am now under CPO warranty and I don't think that technically covers rattles but my dealer has been exceptionally accommodating about making an effort to resolve rattling noises.
Try and see if it only happen when you have the air on, doesn't have to be a/c.
I think it's the propeller on the blower motor on mine, seems to be slightly loose or something and squeak like you're describing.
I have three thing son my list next time I bring it in for a check up...sunroof, broken key and this.
