Had my 11' for a couple weeks and loving it. One thing I've noticed which seems out of spec is I sometimes get a whoosh under the dash when pressing the brake pedal. Its not the pedal action itself, but happens after the press. Seems to happen the most when you are going downhill and pressing the brake more than once in succession. Haven't noticed any difficulty stopping, or lack of brake action but I'm worried something may be going wrong. Dealer said this was 'normal' but I'm not sure they actually drove it and heard it or thought I was talking about the pedal noise itself. Anyone else have this?
