I've been hearing a metallic grinding noise when braking and it stays for a while after releasing the pedal (the car has 29K miles). The car's been into the dealership twice now, the first time they couldn't hear it and charged me $30 for the trouble. The second time I took one of the engineers out so he could hear it. Once he heard it they took it in for another day of work and 12 miles of road testing. However, after looking at the brakes, the pads and the calipers (all were in perfect shape)they came to the decision that it is all normal due to the regenerative braking. I don't buy it, there shouldn't be a metal grinding noise from a car, let alone when its breaking and after. It's like the calipers don't release fully. Has anyone else experienced the same/similar problem? I'll get a recording and post it to the thread.
