"Good Luck!" and let us know what problem is, when/if found.
We have a Nissan that had brakes done couple years ago. Took back complaining squeal noise after drive awhile and let off brake, not applying brakes. Both times we took it back the shop said they could not duplicate the noise. I explained you had drive good 10 to 15 miles in town traffic but doubt that was ever done.
Still dose it, embarrassing when folks hear it and say need new brakes. But, have only put a bit over 1K miles since brake pads replaced.
