Looking for some advice ie-regenerative brake sounds.
A few weeks ago the quiet hum my 2006 FEH makes prior to starting
changed to a loud stutter. I went to the dealer today, was told
that if I didn't have a "code" showing that nothing was wrong, but
I could pay for the diagnostic (42K-out of warranty). OF COURSE
they came back and said nothing was wrong, but I KNOW there is
a problem here. Should I ignore it until something fails, or is there
a way to get them to recognize my concerns?

(PS Haven't been on here for almost a year, but having a ball trying
to "hypermile"-34.2 currently).
