I had a slight vibration on my 2015 at idle, at a stop light, this past summer summer with the AC cycling.I my not have even noticed it if I hadn't saw and read about this TSB 15 046.
I did take it to the dealer a few weeks back and left it with them to analyze it. I picked it up at the end of the day and they said they needed to check with the Honda Territory service Rep. They said the car was out of warranty by a couple of months and I have 37,500 miles.
I called them yesterday to check what the territory service rep said. He said they would cover it at 70/30. For me the symptom is so minor I am not willing to pay anything for the improvement. If it was covered 100% I probably would have them do it.
Must be these TSB's expire with the cars 3yr 36,000 warranty.
