2014 Honda Odyssey touring elite began violent jerking when accelerating on 84 degree day after an hour of stop and go city driving. Occurred nearly 20 times when accelerating from stop light to moderate speeds of 25/35mph. Felt as if hit from behind each transitioning/accelerating 1st to 2nd gear. Very scary. Had my two young children in van who were equally alarmed over violent jerking. Not a single service light went on during these episodes. Had van towed to Honda dealership where they claimed to have failed to duplicate this issue. Do not feel safe with my children in this vehicle. Found other 2014 Odyssey owners experiencing same problem. M.carcomplaints.com/Honda/Odyssey/2014/transmission/vehicle_jerking_loud_clunking_noise.shtml.

When the vehicle is at 5 to 20 mph during acceleration, transmission makes clunk noise and jerks. When this happens there is no response from transmission for few seconds and suddenly shift gears with jerk and pushes the vehicle (feels someone is hitting from back). This issue is random during traffic lights, heavy traffic and freeway merge. Having kids on the vehicle and driving is bigger safety concern and this behavior will likely hit other vehicles as acceleration is exceptionally sluggish and will not respond. When the vehicle is above 45 mph and drives without any issues. Vehicle been to dealer service center twice but they said we are unable to reproduce it and it's really frustrating. This issue has been raised to Honda by many owners but so far no update from them.

From a stop or yield, upon acceleration van jerked. It did this several times all the way back to the dealership. Technicians could not get the van to duplicate this action, so they could do nothing.

The contact owns a 2014 Honda Odyssey. The contact stated that while shifting from park to reverse or drive, the vehicle intermittently rolled without the brake pedal being depressed. The contact had to depress the brake pedal numerous times to prevent the vehicle from rolling. The vehicle was not repaired and the manufacturer was notified. The approximate failure mileage was 4,000. Updated 8/14/14 the consumer stated the engine would shut off when the vehicle was in reverse or drive. When on a hill the vehicle would roll requiring brake action. The dealer advised the failure may be normal. Updated 09/3/2014

Barely over 1 month ago I purchased a brand new Honda Odyssey. This is first new vehicle I have bought in years. Big mistake. I started having trouble with acceleration, the vans jerks, shudders and make loud clunking noises. After I start the van and try to engage in reverse it goes no where...the same thing started happening when I put it in drive. I took it too the dealership that weekend and they told me there was a computer update that should fix the problem... it didn't. two days later I took it back to them and told them it was unacceptable and I wanted it fixed. That was 2 weeks ago. That is 2 weeks that they have had my "new" van that I am paying dearly for. They have admitted to feeling the problems and claim they called the Honda tech line who states I am the only person in the United States that has had this issue. Next week they are installing a new transmission and will continue to try new things until they find a solution. I love the fact that I am making a payment for them to play with my van as the test dummy. If I wanted a van with all these replacements I would have bought an old one and had everything rebuilt and saved alot of money and time that a working mother of 3 kids does not have. This is a nightmare!!!!! please do you homework before you purchase this year model of van.

Transmission makes loud clanking noise and shudders violently at 10-20 mph during acceleration. Acceleration throughout range is exceptionally sluggish and will not engage "passing gear" at highway speeds, making the vehicle dangerous to drive at low and higher speeds. Problem stops when vehicle is stopped and re-started, but may reappear. Dealer has not been able to duplicate problem and states Honda has had no other complaints of same. However, I found almost exact same/similar complaint at www.carcomplaints.com within seconds of searching. I suspect it's happening to more people. In my opinion, this is a safety issue and potentially dangerous situation, especially driving in heavy traffic and the fact this vehicle is very likely to be used for hauling children.

I've noticed on cold nights/days (temps below 40 degrees). The engine temp is slightly lower than normal. The vehicle at a complete stop (at stop lights) then go that while I accelerate it stalls, the gas pedal would go down but would not accelerate then after a few seconds would jerk into speed. I've had 4 other Honda's and this is the first one that has done this.

Driving approx 25mph through town when engine rpms increased a bit as it briefly slipped out of gear, then it caught itself and abruptly went into approx 5th gear (6 speed transmission). From there vehicle was only using 2 gears (~2nd and 5th) and every time it up shifted into 5th (from a stoplight, etc.) it was very abrupt, and made a loud clunk noise - it was so hard it felt like the powertrain was going to be ripped off the engine mounts and out of the engine compartment (seriously). Immediately limped vehicle to closest dealer. Dealer replicated event and determined transmission fluid was overfilled (approx half a quart). This was an issue from the factory and manufacturing process. The selling dealer did not cover/discover this overfill as part of the vehicle sell checklist process (if I were them, not sure I would have noticed a half-quart either). Apparently a half quart makes a big difference in the internal pressure of the transmission which caused this issue. If this would have happened on the highway or otherwise it could have been worse or caused an accident. It was bad enough limping through town. Dealer removed excess fluid and appears to be operating fine (although I now question the longevity of the transmission after this incident). This was obviously an issue during assembly and I am sure I am not the only one that may have been affected. I only assuming that a robot was inadvertently overfilling the fluid on a bunch of transmissions along the way. Can provide VIN as necessary.
