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.

Several people have told me that they hear a banging or thudding heavy sound coming my 2018 odyssey engine. The sound frequency increases as the engine rpm-??s increase. I have seen many reports that state that this symptom could lead to a total engine failure which makes the car unsafe and is caused by incorrectly machined crank shafts (oversized). I called Honda and was told there is no recall at the time ( 8/23/25). In my opinion there should be a recalled. There was not warnings presented. Another failure occurred when mice ate the fuel injector wiring. This caused the engine to malfunction. The cause of this failure I have been told was caused by Honda using wire with a soy based insulation which mice eat.

There is a recall on this engine, same year, same make and model, but not my VIN number, same problem as the recall. Honda NHTSA campaign 23V751000 On [XXX] my husband and I were driving from our home in Scottsdale, AZ to Las Vegas, NV. About one hour from Las Vegas a yellow light came on the dash. I immediately pulled off the highway and looked up what the light meant. The manual said to continue to nearest service location and add oil. I restarted the car and there was a very loud clanking sound and a warning of Emissions System Failure came on. I turned the engine off, called AAA and had the vehicle towed to AAA Las Vegas. In the late afternoon of [XXX] they advised us that the car needed a new engine. Also troubling is that Right Honda did not fully evaluate the engine, but charged $180. They relied on the AAA report and wanted to sell me a used engine, one year warranty, but could not tell me about the engine, other than mileage because it "was on a pallet." 1. Report from AAA 2.

While driving on the highway at speed, without warning or any dash check lights we heard a loud pop from the front of the car followed by white smoke. The engine seized, lost all power, and the along with it the brake system shutdown so the car became uncontrollable on a busy highway. The car was towed to a local honda dealership and is currently being looked at. The vehicle was recently inspected at a honda service center where there was no indication of any engine issues. There were no check engine lights untill the engine seized.

We do not own the vehicle anymore, but I just learned of recalls for this issue and wanted to make sure I submitted this as our lives were significantly affected. In July 2023, on the way home from a trip, we began to hear knocking in the engine and shortly after the check engine light began flashing. We got to the closest mechanic, and they suspected an issue with rods due to metal filings in oil. We had it towed 2 hrs to the closet Honda dealership. Garcia Honda in Albuquerque, NM. After days in a hotel and the dealership making the repairs they thought it was, we were told it was ready to go, they just needed to do a test drive. On the test drive, the engine lights come on again, and on closer inspection, they too heard knocking, and diagnosed engine failure due to rod issues and told us we needed a full engine replacement. We were still 9 hours from home and had missed work for a few days, and being dejected and overwhelmed that we still did not have our car to get home, we made the snap decision to purchase a new car there and -??trade in-?? the odyssey for the bare minimum. We mentioned to someone today that we had a Honda with engine failure, and they brought this recall to our attention. After researching, I wanted to make sure to get this complaint failed, to hopefully help others going through what we did.

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.

High flow fuel pump failure. Discussed at length with Honda repair shop

- Mount Pleasant, WI, USA

I bought a 2018 Honda Odyssey new. When the recall for the fuel pump came out, I had it completed on the emergency basis because it said if you had been experiencing the engine cutting out, to call and get it completed soon. I had had issues with the engine cutting out. Recently, I noticed a loud engine rumbling and rough noise during idling and acceleration. I took it to a Honda dealership, and they diagnosed a failing high-pressure fuel pump that required immediate replacement. There were no warning lights. The most frustrating part is that so many other 2018 Odyssey owners are reporting the exact same issue. It-??s all over forums and Reddit -?" people with Odysseys from around this year are dealing with premature high-pressure fuel pump failures. This is clearly not an isolated case -?" it's a widespread defect that Honda has yet to acknowledge. While Honda recalled the low-pressure fuel pump, they-??ve ignored the high-pressure pump -?" even though it presents serious drivability and safety concerns. I am being forced to pay $1,775 out-of-pocket at a Honda dealership to replace this failed part. I-??m urging NHTSA to investigate this pattern and hold Honda accountable. This is not normal wear and tear -?" it-??s a systemic failure that deserves a recall and reimbursement for affected owners.

Check engine light came on while driving and engine making rattling noise. Stopped vehicle and restarted with difficulty starting and loss of engine power. Towed to nearest Honda dealer and diagnosed with cylinder 3 rod bearing damage. Engine replaced under Honda extended warrenty with used engine per warrenty company preference. Called Honda customer service to report the incident. They confirmed my VIN was not included on the recall for vehicles of the same year with similar issues. They confirmed over the phone that they would file a NHTSA report on my behalf, but I have not seen the report on this website.

While driving Oct-Nov 2023 I noticed a rod knocking sound in the engine and made an appointment with Jones Honda, Lancaster PA for inspection in Dec 2023. While driving to my base in Horsham, PA on [XXX] the engine seized and shut down leaving me stranded with my family. We had it towed to Reedman Toll Honda, Downingtown PA and it was determined by the Honda technicians that it was the same issue that affected thousands of other makes/models of the same year. Honda (American Honda Motor Co.) is recalling certain 2015-2020 Acura TLX, 2016-2020 Acura MDX, 2016 and 2018-2019 Pilot, 2017 and 2019 Ridgeline, and 2018-2019 Odyssey vehicles. Due to a manufacturing error, the connecting rod bearing in the engine may wear and seize, damaging the engine. A damaged engine may run improperly or stall while driving, increasing the risk of a fire, crash, or injury. The technicians verified this is the same issue and we opened a claim with American Honda. American Honda claims that our VIN was not affected and that the technicians do not have the authority to claim it is the same issue and refused to assist. We have service records to indicate the vehicle was maintained, oil and filter changes, other recalls, etc. There is no reason a five year old engine, at the time, should have died without it being a manufacturing issue. This issue put my family at risk and the safety of others. The engine was maintained and verified by Honda certified technicians that it is a manufacturing issue that caused this. We have been talking to American Honda for over a year and half now and they finally closed our claim about a month ago, May 2025, with no resolution.

The Auto Idle Stop system causes the engine to stall or fail to restart after being stopped. The error that comes on sometimes says "Collision Mitigation System Problem" on the dashboard, or sometimes "Transmission Problem. Apply Parking Brake When Parked", but either way it happens when I release the brake to drive again after a stop when the Auto Idle Stop comes on. To fix, I'll have to turn off the car and turn it back on.

There is a recall on other 18 model year vans for the rod bearing failure. This happened to me on my van and it has had regular oil changes and has around 139000 miles on it. This could have been catastrophic for the ones around me if I was driving on the interstate and the bearing gave out and hurt my family due to the engine seizing. The vehicle has not yet been inspected due to this just happening. I am not the only one with this model year having this issue and my vin not being covered by the existing recall. There were no warnings prior to the issue. Oil was always clean and changed on time. This vehicle has a good history report and records.

Automatic Idle Stop function causes car to stall in the middle of roadways. Idle is initiated when car comes to a complete stop at intersections, traffic lights, etc. Instead of rolling back on, engine stalls and brake seizes up, causing us to block traffic in the middle of roadways, intersections, traffic lights, etc. Car does not restart when power button is pushed. Only solution that has worked is to completely turn car off, open driver door and pretend to be ending trip by getting out, closing the door, walking away so car locks, waiting 30 seconds, then reapproaching the car and starting over from the beginning. This obviously causes major issues in the middle of roadways. On one occasion, no solutions worked, the brake pedal completely seized, and the battery had to be jumpstarted, despite the fact that it was a fairly new and undamaged battery. Problem persists even after changing battery.
