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

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.

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.

The contact owns a 2018 Honda Odyssey. The contact stated that while reversing at about 2 mph, the transmission went from drive to park without warning. The vehicle was taken to the genthe Honda dealer, located at 15100 eureka rd, southgate, mi 48195, where the technician was unable to diagnose the failure. The failure recurred. The manufacturer was not made aware of the failure. The vehicle was not repaired. The failure mileage was approximately 33,000. The VIN was not provided.

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.

I have had this very problem in my 2018 ex with nav res. I'll be on the highway, going 65mph+, and I will accelerate to change lanes or pass and the engine will seemingly stall for several seconds. As I press the gas, the car actually decelerates as if it's coasting in neutral. After a few seconds, it reengages, the engine revs a little, and the car begins acceleration. I also often notice that the van does a similar thing when I'm accelerating from a stop to enter traffic or make a turn. When I hit the gas, the car coasts forward for a second before actually accelerating. It is actually dangerous, especially since it has happened when there has been oncoming traffic. I have had it into the dealership multiple times and they 'can't replicate the problem.' Today my dealership told me that I should open a case with Honda, which I did. I was told that the 9-speed transmission was discontinued because consumers 'complained' and 'didn't like it.' They further said that they could not replicate the problem and therefore could not fix it. In the case of my van, it is defective and dangerous. My son is learning to drive and I am fearful for his safety. I have felt in danger in this car myself. When I asked about to whom I could speak to address my concerns, I was directed to 'page 2 of the online owner's manual.' This has happened on numerous occasions and has been into the dealership frequently without resolution.

The 10-speed transmission on my 2018 Honda ex-L Odyssey van slips. This has intermittently happened since the vehicle was new, but it is getting worse over time. The slippage occurs most often when starting after a stop. The engine will rev for to a full second before the transmission "catches" and starts to move the vehicle. Sometimes the vehicle will start with a jerk, other times, the acceleration will be slow. This unpredictable acceleration makes it dangerous to pull out into traffic. I've had several "near miss" incidents where the unpredictable transmission performance almost caused accidents. This is a safety hazard and Honda needs to repair it immediately lest lives be lost.

- Baton Rouge, LA, USA

Owner of 2018 Odyssey exl resnav w/ 9speed at wife is primary driver and we recently returned from a road trip. Vehicle performs very smoothly 95% of the time. The other 5% you can expect abrupt and violent up and down shifts. Further, this is the safety vs annoyance issue, the vehicle will hesitate when accelerating from a stop. This is a factor threat when pulling into traffic. Hesitation can and will cause an accident. Honda of na needs to get to work and take responsibility for this unacceptable safety issue. Someone is going to be hurt.

I had the Honda Odyssey in at least 8 times for a jerky transmission. It was actually replaced at 15,000 miles (1/21/19) with a new one, no problem for another 15,000. Then in Sept of 2019 the problem reappeared after 3 service calls and numerous fax and telephone calls basically Honda customer care said I did not have a problem. Then one day while driving thru busy downtown grand rapids the Odyssey downshifted on its own while the wife and mother in law were driving. My wife almost lost control but was able to pull of the road. At that point I traded the car in. And sent a letter to Honda customer care and betten Honda in muskegon that I suggest the car comes off the road. As I know the next person will have the same problem. The issue is that transmission problem is random and unpredictable and can not be recreated or detected by a computer check. But it is very real. To the point where I was willing to lose 12,000 dollars. Not an easy pill to swallow. My hope is that no one else gets hurt due to this problem, but I can see it coming.

Vehicle experiences rough shifting when slowing down and speeding up in stop in go traffic. It is like it falls into gear, and not a smooth shift. Very disappointed for a $33,000 purchase. This happens on the highway, or on residential roads.

Transmission slipping when accelerating from stationary position or whenever more speed is needed. Happens when going uphill or lane changing when more speed is needed.

- Trabuco Canyon, CA, USA

The vehicle is having intermittent issues with the transmission shifting. The speed seems to vary, the range is between 24 and 33 mph. It seem to be most prevalent after being on the highway for a longer period of time, 45 minutes and longer. Then when aaccelerating gently from a stop it can lurch when shifting, or shift hard and make an audible clunk. Other times, not having been driven for any length of time, in the same speed range, 24 to 33 mph, during gentle acceleration it does not shift easily or smoothly. There is not necessarily a clunk (there can be), but it does not shift normally or smoothly, I would describe it a miss or lurch. In both cases it will shift, but not as it should. This began around 17,000 miles. I am noticing very fine vibrations in the steering wheel and throughout the front end, its not all the time, but it does not seem right. I am unable to associate it with any particular speed or stretch of road, but it did not do this when the vehicle was new.
