New Fiesta - Speed Warning Tone? - Jack
Has anybody noticed a strange intermittent whistling noise which comes and goes if your speed drifts up between 75 and 80 MPH (allegedly) on recent fiestas. It sounds like a wind resonance (not another tellytubbie I hope!!).

It's so consistent on various hire cars it could be construed as a cunning Ford design to deter speeders.

Are Ford that clever, or is it just a resonance overlooked during design, perhaps the aerial?

Any ideas?

This noise comes from the windscreen surround. Your dealer should fix it.

This could be the answer. If so however, it must be a production quality issue as it has ocurred on 5 different rental cars.

Maybe I shouldn't complain as it serves as a good speed reminder, even with the radio on.
