The years in question are the 2006-2008 Odysseys. The problem being looked at is whether air entering the brake lines is degrading brake performance. Honda says air might enter the lines, but that wouldn't change the operation of the brakes. This is not a recall, merely an analysis, and there is no indication yet that a recall will be necessary. Later model vans are being looked at most closely, and NHTSA should release its findings soon.
