I have not, last time i had it to the dealer they blamed it on my running boards being "loose" and claimed they tightened them and it fixed it... The truck did seem better for about a day, but it came back just as bad the next day. I absolutely HATE dealing with the dealership service departments, and mine is filled with a bunch of girls that all share the same attitude as the Beavis & Butthead cartoon character Daria... so i haven't been back yet. However with the cooler weather some other engine bay noises have come back, so i'll likely be taking it back to the dealership again for all 3 noises after my short vacation this week.
