general problems of the 2009 Honda Odyssey

Honda installed a vcm (variable cylinder management) in this engine which shuts down the back three cylinders to save fuel when the car warms up. You’ll know when it kicks in when you see eco on your dash. When the cylinders shut down it starts an abnormal wear and tear on those cylinders. High oil consumption, fouled plugs, the need to repair the back three cylinders and misfiring of the engine are some of the problems. Honda did repair some vehicles if they experienced rough running and misfiring on those cylinders because they knew the issue was the vcm. However, when my 2009 Honda Odyssey started having those problems in 2024 they wouldn’t fix the problem and stated it was too late to fix the engine. The timeline, according to Honda, had passed to repair the damaged engine. I never received a recall for this known safety issue. The engine would cut out and the engine light would come on and it sputtered down the road on three of the six cylinders. Honda knew this was a problem but they wouldn’t fix my engine. If I had brought it in years earlier they would have fixed the known problem with the vcm but they wouldn’t deactivate the vcm to prevent it from destroying the repaired engine. The price to fix the engine was over $4200. I feel they should have repaired the engine and then deactivated the vcm by bypassing the the temperature sensor to prevent it from going into eco mode vcm. The safety of the occupants was at risk due to the lack of acceleration and the ability to drive the vehicle in a normal manner. I feel a safety recall is justified and the sensor should be deactivated to prevent further damage to the engine.

Transmission gears, while driving gears don't engage properly. It struggles to change gears specifically between 3rd to 4th gear. Also when parked and change to drive makes a stump noise.

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.

Tl- the contact owns a 2009 Honda Odyssey. The contact stated that the vehicle violently accelerated without depressing the accelerator peal. The vehicle was taken to an independent mechanic where the failure could not be determined and the contact was informed to take the vehicle to a dealer. The vehicle was not taken to a dealer for a diagnostic test or repairs. The manufacturer was not made aware of the failure. The failure mileage was approximately 70,000. Dr.

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.

Engine light came up. Drive light flashes. Moving into drive is very noisy. Car hesitates to move and changes gear late.

Vehicle above 40 mph Honda dealer refuses to work on it anymore.

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.
