The engine starts to stall. It-??s scary. It slows down to 0 and when you step on the gas it doesn-??t want to go. We bought this van last year and it-??s done it since we bought it. I-??ve read that Honda knows it-??s a problem but there needs to be a recall before someone dies in an accident.

My Idle Stop feature on the car has become very unreliable. After the car enters the stop state, waking up the car has the following difficulties: Almost regularly, the start up process causes the car's audio and electrical to glitch and will put a warning on the dashboard that the collision mitigation system has been engaged. A few times now, the car has simply not woken up from the idle stop state, and the console will tell me to put the car in park to restart, but the shifter won't do anything. I've had to open the driver's side door to reset the electronics, close the door, and then hold the brake and push the start/stop button to get the car to restart.

I was driving my vehicle, slowing down to turn left, when my car shifted into neutral all by itself. The satellite radio went off and the collision warning appeared on the dash. This could have happened on the highway and I could be dead. I called the Markley Honda Dealership here in Fort Collins however their service department was closed for the day. I plan on calling them first thing Monday morning. Also, the heated seat problem appeared on the dash 5 days ago and it works just fine.

Twice reported transmission issues to dealer. They suggested changing transmission fluid, so we did. Issue did not resolve. Check engine light came on. Car won-??t shift gears.

My 2019 Honda Odyssey regularly hesitates from the stopped position or when quick acceleration is needed on the highway. This causes a safety hazard when making turns into traffic because I am not able to accelerate for approximately 1 second before I am able to increase speed. It is a known mechanical defect with Honda and they do not currently have a resolution. I reported this problem to my dealership and was told that this is "just how the Honda 9-speed transmissions are designed" and there is no fix. Not only does this cause performance issues, there have been several close calls when I have made a turn into traffic and when I have had to accelerate to make a lane change on the freeway.

Noticed that a check brake system light came on briefly and then when I stopped at a traffic light, the engine shut down as it is supposed to, but when I lifted my foot off the brake, the car didn't restart and I was stranded in the lane (busy road). Pressed the Engine button, but it wouldn't restart. After about 5 minutes (while I called AAA) I tried again and it restarted. Very dangerous - I see multiple other people had the same experience. AAA came to my house and the battery, alternator, and starter all tested good.

When I try to accelerate it won-??t go sometimes! It hesitates until it just blasts off. Emissions System Problem

When stopping at an intersection multiple times the idle stop turns the car off and the vehicle refuses to start again and all electronics stop working until the vehicle is turned off completely and the driver door is opened. Does not happen all the time so can't consistently reproduce to have a service center confirm. Vehicle has been inspected during other recall repairs and I was told the repairs being done would not fix that issue.

Jerks when downshifting and upshifting. Has been a problem since the vehicle was purchased new off the lot. Is dangerous because of the jerking. Also noticed a clunking noise when transitioning.

When I come to a complete stop and the start/stop motor goes into idle mode (shuts the engine down), I have a problem that occurs after it. It is unpredictable but when I come out of the idle and the engine is supposed to kick back on, my minivan stalls out. This has happened in heavy traffic areas and it takes 30 seconds to a minute to get the van to turn back on as the electrical system malfunctions. Big safety issue that can be scary in the moment. There are error messages that come up on the dash including "Collision Mitigation System Problem", "Brake System", and the center console system will restart. This problem doesn't happen when I disable the start/stop motor as it doesn't go into idle-stop mode. I have read through online forums recently and it appears this issue has happened in other Honda models dating back to 2016 models. This is clearly an issue across years/models and needs to be addressed. The local Honda dealership said they haven't heard of this problem and couldn't replicate. Therefore, there was no repair provided.

Frequently the engine will stall on restart after idle stop system cuts the engine off at a light. Occasionally the stall will lead to a full reboot of the control system taking up to 3 minutes to allow a restart of the engine.

I purchased my 19' Odyssey in March, almost two months ago. It was used with only 19k miles. During the test drive I mentioned to the sales guy (sitting in passenger seat) a strange noise that sounded like fluttering, but only when accelerating 1k-1500k RPM. I didn't think much of it so I made the purchase. Come May 2nd I got the Oil changed (at the same dealership). I couldn't help but notice the same sound mentioned earlier, but even louder. Since then I've recorded numerous videos of the sound, also worth mentioning the speaker crackling. On Monday of this week I took the car in, showed the mechanic the video of the engine noise and speaker crackle. He mentioned he's only worked on one other odyssey with the same engine sound, resulted being the short block. After they were done, I was told by the service writer that they couldn't replicate the engine noise but did change fiber optic connectors for my speaker crackling (crackle still occurs but only on HD signal). I went over to the Service Manager and showed him the videos, we went for a drive around and heard the noise. He said to drop off the car Friday (today) and he'll have a loaner ready for me. I dropped off the van, spoke with the senior mechanic and the manager, they saw the videos and said they are going to take care of it. They wanted to test drive the car, however the sound is much louder when my car is either cold, or before reaching it's regular temps. I will attach two links to this letter that better show the problem at hand. One being my YouTube channel and the other of the forums where many others just like myself share the same problem. https://youtube.com/channel/UCuOrw9CP7Njl2O_EAF4fsFA https://www.odyclub.com/threads/rattle-noise-on-acceleration-revisited.347853/page-36

Six months or more ago, my van started acting as though it is stuck in a gear before it finally shifts to the next gear. At first is happened every once in a while, but it now happens several times every trip and always at speeds between 25-40mph. Additionally, when I press down on the gas pedal, there sometimes tends to be a delay in it responding, so I've been very careful about pulling out in traffic. But recently, it seems to be happening while the van is already in motion. And, just yesterday, when accelerating from a stop, the car lurched forward and the wheels screeched. Regarding electrical issues, just this past December, we were driving home from vacation, and as we were passing through downtown Nashville, the car suddenly lost all electrical power. As the car began to slow, my husband pumped the gas as we were on an interstate junction and had no other alternative. Thankfully, after a 10-15 seconds, everything turned back on and we continued to our way. I've owned the van since Oct 2020 and it only has 57K miles on it. We've had several Hondas over the past 25 years (this is our 3rd Odyssey), and have loved them all. But, I'm very concerned about safety as well as the money spent.

Our car has failed to start 3 times in one week. Our battery has been throughly inspected and nothing appears to be wrong with it. We have jump-started our car in July, and twice this week. (Once yesterday and once today.) We are not sure why this is the case.

The vehicle hesitates. It chokes so badly that it is a danger to drive. I do not know if this is a result of the new transmission type or a problem with the engine. I suspect that the problem is related to the transmission because of how you reach the point where it chokes. Plus the two dealers it was sent to for repair hinted to me that the issue is the new style transmission. Here's one typical example. Sitting at an intersection waiting to turn left. If I take my foot off the brake and apply my foot to the gas pedal without hesitation it typically works fine. However, if I touch the gas, back off the pedal then hit the gas pedal again, I'm left in the intersection not moving for a few seconds. This has become critically dangerous. I have taken my vehicle to two Honda dealers within the first 10,000 miles. I explained the problem and both dealers said the exact same thing. "Yes, we hear this from all the customers with that transmission. It's normal and nothing can be done to correct it." They did nothing further for it. Since the dealer made no diagnosis of it the manufacturer will not address it. I experienced this issue from the very first day of ownership and there are no warnings.

Car accelerates or bucks when changing gears whilst driving. Returned car to Honda garage twice and they claim there is no fault unless engine light illuminates. Car has only 14,000 miles, front tires have worn prematurely and car shakes when applying brakes.

The contact owns a 2019 Honda Odyssey. The contact stated that while driving at approximately 5 mph, the vehicle abruptly shutoff as several warning lights illuminated on the instrument panel. Once the failure occurred, the contact stated that she was unable to place the vehicle into neutral as the engine would not restart. The contact also stated that a warning message that read; place car in neutral, please turn on engine, also appeared on the instrument panel. The contact had the vehicle towed to ken garff Honda riverdale (950 w riverdale rd, ogden, ut 84405) however, the vehicle was not yet diagnosed. The vehicle remained in the possession of the dealer. The manufacturer had yet to be notified of the failure. The vehicle had yet to be repaired. The failure mileage was approximately 34,000.

While driving 25-35 mph there is a hard shift to the next gear. It jerks you forward in your seat. There is also an issue while the heat/air fan is on it continuously cuts out. Also notice a knocking noise at time from the engine.
