The transmission started shifting hard on November 20th, 2021 while driving 60-70 mph on the interstate. I was on a Thanksgiving trip (Indianapolis, IN to Venice, FL) with my wife and three kids ages 8, 6, and 4. We were on I-75 north of Atlanta when the transmission shifted hard up and down around 2000 rpm. After about four hard shifts the van lost the ability to accelerate (no amount of throttle increased vehicle speed); no dash indicators or warnings. At the time we were going around 60-70 mph when we lost acceleration and I had to coast the van to the side of the road through the northern Atlanta traffic. The transmission did come back and I was able to get of the next exit and take the van to the Honda dealer. The transmission continued to hard shift on the approximately 15 minute drive to the dealer. I did leave the van with the dealer, but before I left I tried to put the van in reverse and it would not move. The dash and button suggested I was in reverse but there was no function, and at that time I got a transmission problem warning. Prior to trying to reverse the vehicle I did not get a warning. So while on the interstate when it was a real problem the vehicle did not give any indication of what was wrong; so I-??m glad I was driving and not my wife or someone less capable in a dangerous driving situation. Honda looked at the van on Monday November 22nd and told me I needed a new transmission at a cost of $9,300. The van was purchased in March of 2018 and currently has around 69k miles on it. I don-??t believe anyone would agree that a transmission replacement at 69k miles is acceptable. This transmission failure is on top of the RES problems that have persisted for multiple years now. If Honda doesn-??t contribute financially to the transmission repair, I have no reason to buy another Honda. My van has been nothing but problems. The RES is unreliable for the family and the transmission failure left us stranded 500 miles from home.

The transmission will occasionally not engage in gear in situations where the driver is accelerating slowly from a stop, and then has to let up on the accelerator as to let a car pass, and then applying pressure on the accelerator again. The minivan will stall, not because the engine died, but because the transmission will not engage in gear. It will then jerk in gear causing the tires to lose traction since the engine is reving. The last times this occurred was Nov. 1 and 2, 2021. On Nov. 1st when I was leaving a driveway, I paused to let a car cross in front on me and then attempted to accelerate onto the intersection in front of a semi. The minivan wouldn-??t move since it wouldn-??t engage in gear. My daughter was screaming at me since the semi was barreling down. The transmission then slammed in gear, tires screeched, and the minivan accelerated. I took the minivan to a Honda dealer on Oct. 1,2021, but they couldn-??t find anything. They checked software and DTC and no codes stored or active. This transmission issue has occurred occasionally since the minivan was new but has become much more frequent in the last three or four months.

My 2018 Odyssey at 62000 mileage right now, there is happen a lot of delayed response when accelerating, then start fast, it was scary while I am at middle of intersection waiting for left turn, or at stop site and or red lights. Is this an SAFETY ISSUE? I feel somedays I may get hit accident from this issue.

- Rosemead, CA, USA

The transmission on this vehicle is super jerky when accelerating at low rates of speed and decelerating. The extreme concern is when accelerating from being completely stopped. More than once I have almost been in a major accident because when I pushed the accelerator the vehicle took a second or two to begin and once it accelerated it was extreme to the point of spinning the wheels and the vehicle being moved too late and in the middle of an intersection with a vehicle headed right towards us. If the car had accelerated when the gas was pushed like it should I would have not been in this predicament. This is very concerning and not how this vehicle should perform.

I'm an owner of 2018 Odyssey ex with 9-speed trans. This is my third Odyssey I own. I have two 2016 and one 2018. I'm very disappoint about this 2018 trans and the lack of attention from Honda regarding this known issue. From the part saleperson to the advisor, all noted the issue with these 9-speed transmission. Rattle, hesitation, shuddering, jerking, were some of the ongoing issues. I completed intense research and found tons of people have the same problem. I was rear ended due to this hesitation and miss gear issue while driving. The is a safety issue and needs to be addres before someone is serious hurt.

In the middle of the night my car alarm went off for no reason and I was unable to turn it off because the car was stuck in a loop of powering on and off. An error message on the dash suggested a failure of engine auto idle. I pushed the engine auto idle override button and managed to turn car off. Next morning I jump started it and was able to drive it for a few errands. The following day the alarm went off again. This time pushing the engine auto idle override did nothing. I was able to stop the alarm, but could not break the loop of the car powering on and off. I had to let the battery die. I tried jumping it again but it now won't power on long enough to try to start. Honda told me I was on my own to get it towed in. Tow truck came but there is a serious defect in the transmission ' there is no way to manually shift this vehicle into neutral. You must be able to power the car on and use the transmission push buttons to shift to neutral. Honda is refusing to provide assistance getting the car in to be looked at. I'm lucky this power on/off loop didn't happen while driving, but a piece of trash van sitting in my driveway unable to be moved does me no good either.

The transmission seems to shift to neutral when I try to accelerate to make a right or left turn. It seems like the system is indecisive and it just revs as if it is in neutral. I bought this van new in 2017. My mechanic just did some work and noticed it on a test drive and says this transmission is made by a german company that has this known issue. This is a safety issue because I have almost been T-boned on turns because the car does not move and just rolls for 3-5 seconds. This is a known issue an needs to be fixed

What I need to do?

- Richmond, TX, USA

Car delays when attempting to accelerate when stationary. Car then lunges forward when the transmission engages. At times I'm stuck in the middle of the road as vehicles are approaching. Makes if very dangerous when attempting to cross road.

All warning lights popped up and continued to cycle through when I was driving causing the vehicle to go into a safety/limp mode. Shifting became very difficult and the maximum speed topped out at 45mph.

- North Port, FL, USA

Without warning while driving transmission failed and dropped into a lower gear. This caused a sudden reduction in speed and difficulty in safely removing the vehicle from the highway.

Odyssey transmission system problem and blind spot system problem messages and issue surfaced several times while we were driving on the turnpike, I was unable to backup the vehicle at service plaza and also was unable to backup vehicle while parking on our home driveway! not able to backup vehicle is a huge safety and security issue. I tried calling Honda roadside assistance, but was told tow truck was restricted on Ohio turnpike. Issue surfaced several times. Dealer looked at the issues and performed diagnostic service. Dealer determined ' after codes were cleared, issue could not be duplicated'. I am not convinced the problem is fixed. I would like to know if there are any known issues like this on 2018 Odyssey's with 10 speed auto, electronic press button transmission! a case 11543835 has also been opened with Honda, but have not received any response yet.

2018 Honda Odyssey with 9 speed transmission is dangerously unpredictable when accelerating. Especially from fully stopped condition. It does not matter whether advancing straight ahead or turning into either direction. Terrain conditions do not seem to affect this behavior. The driver may experience widely variable responses to a consistent application of throttle. Vehicle may, without any way for the driver to predict, 1) accelerate with a normal predictable response to throttle pressure, 2) respond to the same throttle input by very slowly accelerating (even if the driver significantly increases throttle input) or 3) immediately. Not move at all while engine revs, then moments later, the vehicle will accelerate so rapidly that it launches into traffic or the tires first lose traction before it launches. In inclement weather the condition is exacerbated into an even more dangerous lack of vehicle control.

- Beavercreek, OH, USA

- Slatrock, MI, USA

The transmission in this vehicle lags and slips regularly when shifting from 2nd to 3rd gear. It is a major safety issue. We took the vehicle in to a Honda dealer to service this problem under warranty and were told that the performance we are experiencing is normal for this specific transmission. It us unacceptable that Honda would allow this transmission to be used by so many in such an unsafe way.
