On Sunday while driving on North Gayton Road at 45 MPH the car started making a terrible sound almost like one makes when overheating and there was a popping type sound. I looked at the dash and it showed a large red "P" which I initially thought was an error code of sometype. I quickly pulled over into the next available turn and noticed when I stopped that the electronic gear shift was in Park and not Drive. That was what the big red "P" was on the dash. It had tried to shift into Park while we were driving. It scared us to death. It has had other minor erratic electrical type problems. The flashers will suddenly be on when no one was near that button, or we will be driving down the road on a bright clear day and the wipers will come on briefly and then usually turn off after a few wipes. I do not know if it is the prom, or the computer, or a short somewhere. This morning it says the battery is low, but it is a brand new battery. We have 67196 miles on the car.

Hesitation of the transmission, the car doesn't go or hesitates. According to the dealership this is "normal" for this type of transmission. This is not normal for a vehicle and if this is "normal" for this type of transmission, there is something wrong with it. I've been lucky that an accident hasn't occurred, but I've been scared it would on multiple occasions. This happens typically in stop and go traffic.

While driving, if I don't make a complete stop (say at a yield sign), and I accelerate, there is a 1-2 second gap between when I press the pedal and the van actually goes. This can happen while fully stopped, while yielding, or even while getting onto the highway. Taking it back to the dealer has yielded only firmware upgrades to the software and recommending a $400 transmission flush. This happens more frequently while in economy mode, but also happens in sport mode. This has been going on for about a year now. The dealer has stated there is nothing wrong with the vehicle, but if I ever have to suddenly accelerate it could mean I will get into an accident.

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.

My van regularly hesitates from the stopped position. This often causes a safety hazard when turning right into traffic or making a left turn because I am not able to accelerate for several seconds and the vehicle feels as if it is stalling out. It is a known mechanical defect with Honda and they do not currently have a resolution. When reported, I was told the mechanical system defects to switching through all the gears before accelerating, causing the delay. I have brought the car into the dealership once regarding the issue and have been dealing with Honda headquarters with no resolution. Not only does this cause performance issues, there have been several close calls when I try to accelerate entering highway or making sharp turns

Vehicle shifts hard in low gears creating a safety risk

- Stafford, VA, USA

The contact owns a 2019 Honda Odyssey. The contact stated that while at an intersection and attempting to make a left turn, the accelerator pedal was depressed however, the vehicle failed to respond. The contact waited approximately 3-4 seconds and depressed the accelerator pedal again and the vehicle responded. There were no warning lights illuminated.

Car has 22,000 miles. And has intermittent transmissions issues. After a stop, I accelerated thru and intersection then when I pulled my foot off the gas to slow down the car engine revved up so loud, really loud. But there was no movement. Also coming off of a stop the car doesn-??t go sometimes. I have to push the gas more. If I-??m on the freeway at high speeds and I release the gas because I know the traffic is slowing up ahead. The car will shift down loudly and sometimes jerk.

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

The Emission Control System error keeps coming on and going off. This time (08/22/21) van stopped while I was driving it. The Honda Darcars in Bowie, MD has stated they will not look at the van and they can't diagnosis the problem without the system error being displayed on the van when it is brought in for service. No, the van has not been inspected yet. The Emission Control System error light comes and has come on several times, but it keeps going back off. As, mentioned before the Honda Darcars in Bowie, MD has previously stated they will not look at the van. I've contacted the Honda Corporation prior to this incident to complain about the dealer not wanting to look at the van.

Our 2019 Honda Odyssey transmission failed while driving my kids in early 2020. The minivan was towed to Grappone Honda in Concord, NH and the transmission was replaced. The new transmission now jerks and stutters particularly at low speeds (20-40 MPH). I am afraid it is going to fail again and place me or my family at risk for being in an accident. I took the minivan in for service on January 6th of this year and was told that the transmission was working fine. This transmission is clearly not working correctly and I am concerned we will be in an accident.

- Londonderry, NH, USA

Highway driving straight on level ground at 70mph. Hit gas to change lanes and van slowed to 55mph before it picked up speed again. 1300 miles later on same trip driving 60 mph up a small incline hit gas and van slowed down to 45mph before it picked up speed again. Two different Honda dealers told me they couldn't help with this issue. 36,485 miles on van when first problem occurred.

- Maplewood, MN, USA

Transmission is slow to get into first gear. There is a noticeable and significant delay when going from a complete stop and pressing the gas to go quickly. This occurs more frequently before the engine warms up. I have spoken to the local Honda dealership and they say its just how the transmission is supposed to work. This has occurred since the vehicle was brand new and has persisted til now with thousands of miles on the van.

- Duncan, SC, USA

The 9 speed transmission jerks and bangs while moving. Driving from slow speed the car jerks and stalls. At hwy speeds the car bangs very hard - it seems like it is being bumped. We thought it stalled at hwy speed after it banged very hard. Honda service says they cannot find problem. We have been driving car for 2.5 years - and the issues are getting more frequent and harder.

- Port Saint Lucie, FL, USA

Experienced issues when trying to accelerate from a stop, merging into traffic, driving uphill and changing gears at low speeds. Here are the specifics: Sudden, unexpected and violent shaking and jerking (commonly referred to as 'juddering' or 'shuddering') hesitation when pressing on the gas pedal surging, clunking or hard 'downshifting' also after a recent recall service done on the doors, I did not notice any change, the door does not respond well upon pulling the door handle, sometimes it needs to be pulled upon multiple times for the automatic side door to open.

When the vehicle is parked, the head unit malfunctions and stays on, especially after being used for apple car play. It has left us stranded and had to be towed once, two other times, jumped as a brand new vehicle. More importantly, the transmission has issues. Between 20-30 mph, the vehicle disengages with the transmission, loses power, then 'clunks' back into gear. It makes the driver and passengers unsteady, and causes unanticipated slow downs and speed ups. Adult passengers in my vehicle have yelled out in confusion over the loss of power and speed. When the vehicle is stopped, it sometimes hesitated to go into first gear, and then 'clunks' into first, experienced as a 'neutral drop' as if one is driving a manual transmission. Overall, the transmission is clunky, and leads to unexpected vehicle movements, unsteady feedback, and extreme discomfort and worry.

While in motion on the highway the speedometer and center infotainment system crashed, went black, and began to restart shortly after. While rebooting the car shifted into neutral and there was no warning of the gear changing. The car was able to get off the highway, and had to be towed per the dealers recommendation for safety.
