Engine has been running very rough the last 20k miles, and East Coast Honda in Surfside Beach, SC noted engine bearing wear prior to the rough engine performance during a service visit in May 2023. In June-July 2025 driving on [XXX] driving between Washington D.C. and Surfside Beach, SC, we went to pass and the engine cut RPM's drastically and went into 'limp mode' nearly causing an accident with the sudden decrease in speed. We have asked American Honda Customer Service [800-999-1009] to provide an engine evaluation but they have declined and have stated our VIN is not included in the rod bearing recall/TSB. We did mentioned about the further investigation for 2018 Honda Odyssey's but was advised any action we take would not be compensated since the vehicle is out of warranty by date and mileage (73,000 miles).

Vehicle has a vibrating shake when you go about 26 to 40 miles per hour like it does not know on what gear to be me I took the car multiple times to the dealership, and after charging me hundreds of dollars they had the face to say it is what it is. That the design of the car. I even called the corporate and no one really cared. I am always scarred that engine or transmission will fail and cause an accident. On the last trip, as I was stuck in traffic, stop and go was hard on this condition as car wants to think on what gear to be.

The transmission is very jerky and has completely lost power before. It has refused to shift and stalled in the middle of the road. It is very scary.

Rod knock diagnosed and confirmed by dealership July 15, 2025. Van is currently at dealership and is available for inspection. I have paused work to allow Honda (case 15705425) and now this team the opportunity to diagnose and inspect first hand. Inspection and first hand visuals have only been completed by certified Honda dealerships. All warnings and my concerns are documented in our ROs with Honda dealerships. When any light or reminder came on, I immediately took the van to Honda for service. Safety: slow starts and sluggish acceleration. Noise that was not normal. Out to eat 30 minutes away from home July 13 and van wouldn-??t start. Dealership thought initially battery but then kept van overnight and nod rock confirmed. Also repaired back suspension. Additional details: Problem has been reproduced and confirmed. Have been experiencing slow start, van not driving properly. Our family went out to lunch July 13 and van wouldn-??t start. Waited handful of minutes and then started. Immediately took to dealership next day. Honda dealerships have done all servicing and repairs on this van. (I was told there are 55 repair totaling $22k for your research purposes.) Honda notified me July 29, 2025 that they will NOT offer any assistance and/or goodwill because of the age and mileage of the van. Escalating case 15705425 up Honda chain - we have been very loyal to Honda. As of today, July 31, 2025: Van sits at dealership; has been there since July 14, 2025. I have been advised not to drive the van, esp on the highway. I want to keep the van and want to drive it for many more years. Took very good care of it and followed all of Hondas recommendations for servicing. Just put brand new tires front suspension (March 2025) and rear suspension (July 2025) on it as well. Appreciate your investigation. I-??m working diligently to do the right thing and allow the proper people time to investigate the van before any work begins on the engine.

The contact owns a 2018 Honda Odyssey. The contact stated that while depressing the accelerator pedal, the vehicle failed to respond as intended. The contact stated that the failure has caused the vehicle to hesitate while attempting to accelerate. The contact stated that the failure had occurred on several occasions while driving on the interstate and the freeway. A dealer was contacted. The vehicle was taken to the dealer, where it was diagnosed, and determined that the software needed to be updated and the vehicle needed to be driven approximately five thousand miles to correct the failure. The vehicle was repaired, and the transmission was replaced once before. The manufacturer was notified of the failure; however, the warranty department failed to return the call. The approximate failure mileage was 108,900.

As reported previously to Honda the vehicle jerks when accelerating at high speeds.It was recommended to die a transmission flush which was performed and did not resolve the issue.slow acceleration at times is also a safety issue especially on highways.

Honda issued a recall on the fuel pump December 2023. They did not have any parts available to replace mine. I had brought in my Odyssey Elite to Space Coast Honda multiple times before the recall stating my engine wouldn't crank. I was unable to get the fuel pump replaced until December 5, 2024. ONE YEAR after the recall. I am now getting Emissions System Problems and Stop Driving When Safe Engine Temperature Too Hot. The dignostics that were pulled were P219A Secondary P219A, P0420, P219A. Also, my intake manifold gaskets are leaking coolant. I have had nothing but problems with this van since April 5, 2023 with my car not starting and stalling. My kids and I were stranded at their school two times and there were multiple times at my work. I don't believe I should have to pay thousands of dollars for these items to be replaced since I believe they're an issue due to me driving on a faulty fuel pump. I even called Honda Customer Service multiple times and they told me to keep driving it even though I expressed concern for my kids and having been stranded multiple times. Both dealerships said there was nothing wrong even though I brought it in multiple times for the same issue.

Transmission failure. We had issues with acceleration and hesitation. When brought to the dealership they didn-??t find anything wrong, but then the transmission ended up failing completely.

- Mooresville , NC, USA

The vehicle would make noises and stalls during accelerations and decelerations. It would struggle to shift into gear, especially from 1st to 2nd gear. When the vehicle comes to a stop at traffic lights or stop signs, it's really hard to get the car to move when accelerating. In high speed on the highway, the vehicle would struggle to increase speed when accelerating and the vehicle would automatically slow down and get weighted down. This would result in having to pull over. Sometimes, the vehicle would not be able to be put into Park, and automatically shifts to Neutral not allowing it to be put into Park mode. When attempting to put it back onto Drive, the vehicle would not go and emission and transmission warning would start flashing. The majority of the time, the emission or transmission warnings would not flash. This is very frightening because I was not able to control the speed of the vehicle, and luckily when the car automatically shift to N and came to a stop, I was able to pullover to the side of the busy highway right on time. The car has been inspected for the same issues in the last 3-4 years by the dealership for the same problem. The transmission fluid got changed and that was all. Now it's happening again.

9 speed transmission issue: Ever since I purchased this vehicle around 50,000 miles in February of 2021 (mileage currently at 118,048), I noticed a very obvious delay in acceleration from a complete stop. Changing to eco drive mode and sport mode changes slightly, but still has delay. Transmission fluid has been changed 3 times since owning this vehicle and everytime it has, there was no noticeable changes in symptoms. Delayed acceleration occurs more consistently at normal operating temperatures. Brought vehicle to honda dealership after purchasing. They performed a TCM software update. Problem still occurs to this day. Multiple occasions occured where me and my girlfriend are driving and attempting to make a safe left turn only to proceed, but in process of attempt, the vehicle delays while facing oncoming traffic.

My 2018 Honda Odyssey experienced a heavy snowfall in January 2025. The control panel displayed an alarm, Power Tailgate Problem, and the trunk door could not be opened. I asked a professional who pointed out that it is usually due to water intrusion into the control unit located on the rear driver's side body panel, which causes the tailgate to fail to open, close normally, or even open accidentally. They believe that this is a manufacturing defect caused by the manufacturer and there is a safety hazard. For safety reasons, I went to the dealer for an inspection. They said they could not find the cause but that the control panel was broken and needed to be replaced. I had to spend a lot of money to replace it. But I still think that the problem was caused by the manufacturer itself.

- Belleville, NJ, USA

In several occasions there is a delay in acceleration. This typically is happening when I take off from a stop sign and turning, others I have literally been on highway merging and loss all acceleration Al though I can hear rpm ramp up, there is no action till 10-15 seconds later. I am very lucky no was injured in that instance and could have been a terrible accident going 70+. I see this is an ongoing issue, and because it is not consistent in manner people fail to repair/research issue.

I just had several recalls completed on my van. The issue that they couldn-??t fix (which I have seen on so many message boards) my car stalls when starting from a stop. If I-??m at a stop sign and press the gas nothing happens for 2-3 seconds and then it will catch and take off throwing everything in the car and the people forward. It is terrifying! I-??ve had it happen with cars approaching and just been a sitting duck, thank the Lord it engaged in time. This seems to be a very prevalent issue and I don-??t understand why a recall hasn-??t been done before someone dies. My trunk also doesn-??t work automatically anymore and they said I had a leak that would be $300 to diagnose and $500 to fix. I know ther are lawsuits for both of these issues. Recalls need to be issued.

Issue-1 High pressure fuel pump in the engine bay (no the fuel pump that was recalled for some VINs) failed at 88000 miles. There was a loud motorcycle exhaust kind of sound coming from the engine bay, which is more audible from inside the cabin than from the engine bay itself. Took it to service center for a 1500$ replacement. Wrote to Honda customer care, but they rejected by claim and goodwill refund saying there is not recall for this item. It is example of poor quality of Honda these days especially with this 2018 Nine speed model. Issue-2 MAJOR SAFETY ISSUE. The vehicle doesn't accelerate while moving from a complete stop or turning into a busy intersection, making us prone to big Collison from oncoming traffic. The vehicle lags for 3-5 seconds before it accelerate rapidly. This is an ongoing issue with this model which Honda ignores and is a disaster waiting to happen. NHTSA should look into this and recall all HONDA 2018 9 SPEEED ODYSSEYS to fix this issue. It is been 6 years and Honda comfortably ignoring this safety hazard especially for a vehicle meant for kids.

The contact owns a 2018 Honda Odyssey. The contact stated while stopped, the accelerator pedal was depressed; however, the vehicle hesitated while accelerating. On another occasion, the contact stated that while his wife was driving, the message "Stop Driving when Safe - Transmission Failure - See Owner-??s Manual" was displayed. The contact stated that his wife pulled over to the shoulder of the road and parked the vehicle, and the vehicle became difficult to shift out of park. In addition, the contact stated that the RPM occasionally fluctuated and there was a delay with the vehicle responding. The contact also stated that the transmission was shifting hard. The vehicle was taken to a local dealer where it was diagnosed with an internal cylinder failure and that the 9-speed manual transmission needed to be replaced. The vehicle was not repaired. The vehicle was taken back to the same local dealer several times; however, no failures were diagnosed. The manufacturer was made aware of the failure by the local dealer to assist with the cost of the repair. The failure mileage was approximately 36,000.

When trying to accelerate from a stop either in an intersection or from a driveway the vehicle takes a long moment before it responds... leaving my family vulnerable to cars coming from the opposite direction. I think it's the transmission but it could have to do with the fuel intake... it has been ongoing for months and months. The dealer has attempted to rectify but to not avail....very dangerous
