Hello,
I have a 2003 Honda Pilot, 230k miles, automatic, which has developed an unusual trait that the local Honda dealership cannot pinpoint or fix.
During normal acceleration from 0 thru to, say, 55 (e.g., from sitting at a stoplight), there can be a very loud "growl" that seemingly eminates from somewhere under the middle of the car that occurs when the speedometer reaches approx 35 mph and then again around 48 mph.
This growl stops if I cease pressing the accelerator pedal, and make sure that I'm not maintaining the vehicle speed around those mph points. It doesn't seem to be present when decelerating back thru those mph points.
Any thoughts please?
Many thanks.
Why are you taking a 22-year-old vehicle to a dealer for service? That will usually be the most expensive option, frequently not even the most skilled. With a vehicle that old chances are most of their technicians were in diapers when that thing was manufactured. A good independent mechanic would be best. (Chain shops such as Midas, Pep Boys, and Firestone are also to be avoided.)
You might first check the obvious things like wheel bearings, drive axles, universal joints and propeller shaft center bearing. Check that nothing in the brakes is dragging, like rusted dust shields. You could also use a noise-locating device such as the ones Scotty has demonstrated in his videos. (Noise can telegraph all over a car and the source is not always where it seems.)
