Ford Escape Hybrid Squeaks & Rattles
However, I don't think the noise is coming from the brakes as a couple of the others above have suggested. And in our case it has nothing to do with making turns. It is totally radom and naturally when we make an appointment with the dealer there is no noise. We took it to the dealer the other day when it was making the noise and they would not come out and listen. We were told again to make an appointment so we did and NO NOISE!
The reason I do not feel it has anything to do with the brakes is the chirp, chirp high pitched noise occurs with each revolution regardless of the brakes being applied or not, or applied lightly or hard or even riding them and the faster you go the more frequent the chirp, chirp. If it were the brakes or pads I would expect some change in the volume of the chirp or that it would go away as the brakes are applied.
I have met another escape hybrid owner having the same problem and his dealer could not find anything wrong but like us when he takes it in the noise does not occur.
I would appreciate any thoughts or help from others that have experienced the same problem.
