2009 Honda Odyssey. Issues on the automatic transmission. On 4th gear just shudders either downshifting or up shifting while driving. And besides all this also makes a knocking sound either backing up or moving forward. Besides makes a humming sound from transmission when driving.

While stopped at a 4 way traffic intersection w/light and with foot on the brake, the engine raced on it's own causing the car to surge ahead unexpectantly. I had to take it out of gear to avoid an accident.

My 2009 Odyssey 06/05/15 it currently has 115,000 miles on it. This is the second engine light dealing with the transmission. When I first got the car I had it routinely serviced at the dealership. The first time it was the clutch this time it is the torque converter, so all internal. The gears are fine until 5th or overdrive.

On May 12, 2012, I was driving about 50 mph when the van started to sputter. I came to a red light and the car acted as if it were about to cut off. The check engine light started blinking along with the vsa light. It rode very rough all the way to the closest Honda dealership as I was not in my hometown. They informed me that one of the spark plugs needed to be replaced. I went ahead and replaced all of them to the tune of $308.23. On November 23, 2012, I was driving about 60 mph when the same thing happened. The mileage was 105,001. Again, I was out of town and drove the car to the nearest Honda dealership. They said the #3 spark plug had fouled out. I told them to replace only the #3 plug. On my receipt it says, "retrieved code P0303...misfire #3 cylinder...found spark plug fouled out. Possible faulty valve seals...replaced spark plug and performed PCM software update." That cost me $138.76. On the drive home the air conditioning started to act up. It would run but sometimes it was cold and sometimes the air was not. On November 24, 2012, I took the car to the Honda dealership that I normally use. They couldn't figure out what was wrong with the air conditioning except for a dirty cabin filter. They replaced it and charged me $131.97. However, they said my brakes were worn out. That cost $359.68. Then there was the brake fluid exchange, transmission fluid exchange, and power steering flush. All in all the visit cost me $1049.61. Funny, on November 19, 2012, I had taken the van in for an oil change and they did a courtesy inspection. No mention of brake problem. November 26, 2012, car dead, wouldn't start. They replaced the battery under warranty. December 3, 2012, car dead again. Invoice reads, "A/C clutch relay stuck killing battery making A/C compressor run even when A/C off." Fixed for free due to all the problems.

I just bought 2009 Odyssey from used car dealer at 37125 miles and on the first day itself I noticed few problems with the van which is still under power train warranty. 1) it makes a noise with little jerk during startup, seems like transmission issue 2) steering wheel gets lots of vibration between the speed of 45mph and 57mph and looks like van is being dragged... 3) at the speed of 40-50mph there is wind sound coming underneath of the van looks like it has some kind of resistance by the badly designed aerodynamic body and which makes you feel that car will be dragged by the wind. I hope Honda should consider this issue seriously as transmission may cause accident any time, even wind drag and steering vibration may definitely cause an accident.

Transmission downshifts are extremely rough, especially from 45 mph. When slowing down from this speed and re-accelerating from 25 mph (as in slowing for an intersection or traffic), the downshifting and upshifting are both rough - to the point of wondering whether the transmission will fall out, or not. This condition has existed from the day I purchased the car. Took it to the dealer in February 2010 for a Honda-requested transmission programming update. That didn't do anything.

2009 Honda Odyssey LX. 2 times I was stopping and pushed the brake and accelerator at same time. Motor was racing and ABS was coming on - very frightening as I did not know what the problem was and motor is very powerful. Almost rolled into busy 55 mph intersection first time and almost hit basketball post in driveway second time. Have never had this problem with a vehicle and have been driving for over 30 years. Plain sneakers were being worn - not winter boots. Seems to be little difference in height or location of brake pedal with respect to gas pedal.
