Multiple failures. Brakes problem, transmission, rough idle & engine surging, steering column controls and others. The automatic door would not open or close, the transmission did not shift properly and the dealer was unable to duplicate the problem. The brake pedal shuttered, the brakes would catch without being applied. The consumer was told the steering column control switch had a short, however the next day the horn honked and there was an odd noise in the steering column and the interior lights flashed multiple times.
When shifting up from a lower gear (from 1st to 2nd) most notably at low speeds, around 20 to 25 mph, the engine feels like it is revving higher than normal before shifting into the next gear. When it does shift, it shifts hard and makes a clanking noise. It feels as though the transmission is sticking, preventing it from changing gears in a normal fashion. I have not noticed it occurring at any specific time, it seems to happen at random intervals when driving at lower speeds. I have taken the van in for inspection and the technician could not recreate this problem. Took van on July 08, contacted Honda, the problem still has yet to be resolved. This is one of six problems I had to take the van in for. After having the van for two weeks, only two non-mechanical problems were partially resolved and one non-mechanical problem was resolved completely.
