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

- Lake Charles, LA, USA

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.

Collision mitigation system problem error keeps appearing randomly on the screen!

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.

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.

- Washington, IN, USA

2019 Honda ex-L has exhibited a knocking noise from idle to around 2000 RPM under load since new. The vehicle currently has 10,000 miles and has been to 3 separate Honda dealerships a total of 7 times. Honda can replicate the engine knock, but has refused to take the actions necessary to diagnose the cause. The vehicle has been reviewed by a 3rd party ase certified mechanic that cited the noise is not normal.

On November 11, 2019, I sent my Honda Odyssey to a Honda dealer for maintenance. Everything went normally. After the maintenance, I drove my car back home. Every day, I go to work and work normally. About 10 days after the maintenance, the engine light suddenly turns on. After the car was turned on, the engine lights returned to normal. Every day when I went to work, I found that there was a pool at the bottom of the front of the car. I wonder if it was water or oil" I didn't care too much just after finishing the maintenance. In the state of the car, I drove it for another week. At the end, the engine light made a sound and I checked that my engine oil was almost gone. It's hard to believe. The engine oil that I just finished maintenance was gone within 20 days. This is too scary. The engine ran out of oil. I had driven for so many days. It's just killing. I returned the car to a Honda dealer for inspection, but just helped me fill up the engine oil without any explanation. This way I can't accept it. Please help me defend my rights. What causes the loss of engine oil" find out later I'm afraid I'll die. At present, the right rear tire of the car shows that the air pressure is not enough. I checked that the tires are not piercing, and I also performed a lot of air refills, which did not work. It should show that the air pressure is insufficient. Thank you for auditing my issue to help me complete my rights. Now I think that the engine is scared without oil.

Initially the vehicle would randomly turn off while driving, it was not the idle stop since it is deactivated before driving. The dealer eventually said it was the battery. Then the infotainment system stopped working, the radio was replaced after a week of being at the dealer. Now 3 weeks after repair, the infotainment system does not work. Has a noise that comes out of the speakers like sparks, has a chemical smell, no res usage, no cabin watch or cabin talk. Everything that made the elite trim desired does not work.

While driving at low speed in the process of shifting between 3 and 4th gear van shifts very hard. So much so that at times my body is thrusted forward which causes me to momentarily lose sight of road. While shifting it seems to vehicle seems lunge at higher speed. This occurs at low RPM and will usually occur when speed hits 24mph. Hard shift also occurs when slowing down but not as common. This occurs when driving on stop and go traffic when it requires driving at lower speeds. When vehicle was 1st purchased this was not experienced, it was until after 6 months that this started occurring. Had dealership look at vehicle and they were able to replicate issue and informed me that vehicle was operating as intended. I also contacted Honda North America and they said they couldn't help since dealership said it was operating normally. They suggested I review my consumer rights brochure if I wanted to take additional action. There are various post online with exact same issue. My concern is safety of my family and feel there is flaw in the design which Honda is not willing to accept responsibility nor willing to fix the issue
