Rear mount is broken
Was told by Honda dealer that all 3 engine mounts may need to be replaced, but recommend replacing the rear engine mount first. Cost = $1,000.

There was allot of engine vibration to our van. After taking the Van to the dealer, the mechanics found that all three mounts were destroyed and needed to be replaced. I am glad the mounts were still covered under and extended warranty.
