2018 Honda Odyssey Engine

2018 Odyssey EXL engine seized up at 111k miles. There's now a bunch of metal shavings in the oil. The engine will not turn over.

A small "knocking" noise was noticed a couple weeks or so ago in my 2018 Honda Odyssey. Noise got progressively worse. Vehicle was taken to the Honda Dealership for assessment/repair. Was notified by a service technician that a rod knock was present on the lower end of the engine and that the engine needed to be replaced. Options were: new engine, used engine, or trade in my vehicle towards purchase of a new one. All maintenance records are meticulous and performed by a certified Honda service department.

This is in relation to Investigation PE25008. The engine in my 2018 Honda Odyssey Elite failed at 91,307 miles due to a connecting rod bearing issue, despite perfect dealership maintenance.

The contact owns a 2018 Honda Odyssey. The contact stated that while stopped at a stop light and attempting to make a left turn on an exit, there was a knocking sound coming from the engine. The contact called 911 and the Fire Department; however, there was no fire. A dealer was contacted. The vehicle was taken to the dealer to be diagnosed, and it was determined that the engine and starter needed to be replaced. The vehicle was not repaired. The contact related the failure to NHTSA Campaign Number: 23V751000 (ENGINE AND ENGINE COOLING); however, the VIN was not included in the recall. The manufacturer was notified of the failure and confirmed that the VIN was not included in the recall. The failure mileage was 167,000.

A rattle noise when initially pressing the accelerator pedal. When starting a vehicle, I had to press the start button multiple times. Kept stalling. All the lights on a dashboard started flashing. Saying check engine! We took it to the dealership and they confirmed engine problems. This was their diagnosis: Confirmed concern - found noise coming from engine internally due to CYL NO 2 rod knocking - oil heavily contaminated w/metal particles - recommend engine replacement! Mileage is only 93805.

The vehicle started running rough and the check engine light with other error lights were coming on the dashboard display. 1. Engine Failure due to connecting rod/bearings 2. Vehicle ran rough and struggled to start 3. Problem was reproduced and confirmed by dealer (as seen in attached invoice) 4. Vehicle has been inspected 5. No warning lamps or messages prior to incident Sortly after I replaced my engine (per dealer recommendation) Honda released a recall (NHTSA Recall No. : 23V-751) but said that my vehicle was not covered under -- even though it appeared to have the exact same issue as my vehicle... they said that the recall was only for a smaller set for engines produced as a specific manufacturing plant... and I believe that it is likely more wide spread.

Before my vehicle reached the 100,000-mile mark, the check engine light began appearing intermittently. I brought the car to my local dealership multiple times, but they were unable to provide a diagnosis and repeatedly reset the light. Once the light remained on permanently, the dealer finally identified a known Honda recall/extended warranty issue and replaced the spark plugs at no cost. However, approximately six months after that repair, the check engine light returned. The dealership has now diagnosed a failure in both the front and rear catalytic converters at a cost of $5200 to replace them. I need to replace to pass my state of Illinois car emissions tests. I have been working with Honda Goodwill Assistance (Case #161-655-70), but their offer to cover only 20% of the replacement cost is unacceptable. This failure is not a standard "wear and tear" issue; it is a direct consequence of the spark plug issues I repeatedly attempted to address before my warranty expired. I was told the 20% determination was based on my vehicle exceeding 100,000 miles, but this fails to account for the fact that I brought the car in for this specific issue multiple times while it was still under warranty. I am looking for Honda corporate to acknoweldge the new spark plugs they directed my dealer to install caused this issue and cover the cost of the repairs. My local Honda dealer service manager, Brian, is willing to speak on this issue on my behalf. He can be reached at [XXX] .

Engine failed while driving, will no longer start. Mechanic believe it is either connecting rod or main bearing failure. It has not been inspected by the manufacturer and will be sold to another person as is. No warning lamps or messages were present prior to the failure and didn't appear until after the failure.

Engine has a rod knock problem at 72,000, miles. Vehicle will likely need a full engine replacement.

Engine knock due to a spun bearing

Rod bearing knock

My car needs a complete engine replacement due to "rod knock" or "bottom-end failures." It's my understanding that some Honda vehicles were recalled due to this (Recall 23V-751). And that there were other vehicles having issues beyond the scope of this recall (Query RQ24013). I'm disappointed because my Honda mechanic and independent mechanic have cited my impeccable service records and have told me there is nothing more I could have done. This feels fraudulent.

Engine damage from connecting rod bearing wear. The dealer inspected the vehicle. The dealer confirmed that the damage was caused by a connecting rod bearing. The engine had to be replaced. I was told by the dealer that the VIN did not fall within the recall range. Therefore, I had to pay for the engine replacement myself. The engine damage was the same as the NHTSA ID Number: 23V751000 recall.

The contact owns a 2018 Honda Odyssey. The contact stated while driving 60-62 MPH, there was an abnormal sound coming from the front of the vehicle, and the vehicle lost drive power. The check engine warning light was illuminated. The contact pulled over to the side of the road. The vehicle failed to restart and was towed to Tire Choice Auto Service Centers, where it was diagnosed and determined that one of the engine banks had failed. The mechanic determined that the engine needed to be replaced with a used or brand-new engine. The vehicle was not repaired. The contact related the failure to NHTSA Campaign Number: 23V751000 (Engine and Engine Cooling); however, the VIN was not included. The dealer was notified of the failure and informed the contact that he would receive a call back later. The manufacturer was notified of the failure and informed the contact that a case would be filed, and the contact would receive a call back later. The failure mileage was approximately 132,000.

I have a 2018 Honda Odyssey, with 66,855 miles. I maintain my vehicle with regularity at my Honda dealership. On [XXX], I was driving home from Las Vegas, NV to Pasadena, CA, when near the state line at Primm, NV, I started hear sounds from my engine and it started losing power. I had to pull over and then had my van towed to a dealership in Las Vegas, NV. The van is available for inspection. The problem has been confirmed by the dealer where i paid for a diagnosis to be performed. The engine light did turn on prior to me noticing the engine problem and a low oil light came on later.

At highway speed on cruise control the engine went out. Van only has 118,000 miles on it.

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.

My 2018 family van purchased brand new. Exclusively serviced at dealer. Immaculately maintained records kept. Driving 70 mph on toll road while driving to dealer for service, car lost power and had to be towed remainder of the way. 100k service done at dealer, 40k miles later car had to be towed back to dealer due to broken rods. Honda says my vin# not effected yet car is inoperable for exact issue with open recall effecting rods. Recall states cars effected produced 2015-2020. Honda offered for us to pay $10k for new engine and they would cover remaining $4k. We do not believe we should get stuck with larger portion of payment when Honda has a known issue with part. Research on line states many more cars affected than the 250,000 initial recall. We appreciate NHTSA’s 2nd probe into this issue.

The contact owns a 2018 Honda Odyssey. The contact stated that while parked on the shoulder of a busy interstate, the vehicle failed to restart. The vehicle was later towed to the local mechanic who diagnosed that the rod bearings had failed, and the engine needed to be replaced. The vehicle was not yet repaired. The local dealer was notified of the failure and informed the contact that the VIN was not included in NHTSA Campaign Number: 23V751000 (ENGINE AND ENGINE COOLING). The contact stated that the vehicle had experienced the failure listed in the recall. The manufacturer was not yet contacted. The failure mileage was 100,000.

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.

While driving vehicle, check engine light began to flash. Vehicle was moved safely to side of road and turn off. Vehicle was allowed to sit for more then five minutes and started again. no check engine light or other indicators were illuminated. Vehicle was driven another 60 miles when suddenly multiple warnings appeared with a solid check engine light. Vehicle was moved to a safe location and parked. Vehicle was transported to a Honda dealership the following day and was discovered to have metal in the engine oil due to connecting rod bearing failures with grooves worn in the crankshaft.

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.

My Van has only 110,000 miles on it. Yesterday I was driving my family home from a sports event my wife myself and my four kids. I got a flashing check engine light and was able to pull over, but it was an unsafe area on the side of the interstate. After sitting there for a while. we were able to get the vehicle to Honda. Honda is telling me that it is bad rod bearings. But that my vehicle falls outside of the recall that is already issued for bad rod bearings in a van that is the same year as mine. This rod bearing issue put myself and my kids in an unsafe position.

My 2018 Honda Odyssey (VIN: [XXX]) experienced a catastrophic engine failure due to a spun connecting rod bearing in Cylinder 4. While driving, the engine suddenly began making a loud knocking/tapping noise. I immediately drove the vehicle to the Honda dealer, and as I was pulling into the service bay, the engine completely seized. The dealer confirmed that the engine suffered a spun bearing in Cylinder 4, with severe crankshaft and connecting rod damage. The failed parts and metal debris in the oil system are available for inspection if requested. This failure occurred without any prior warning lights, messages, or check engine indicators. There was no advance notice other than the sudden onset of knocking just before failure. The defect caused loss of engine power and risk of stalling in traffic, which could have easily resulted in a crash or fire. This type of failure is consistent with Honda Recall 23V-751, which covers connecting rod bearing defects caused by crankshaft machining errors, and also matches the ongoing NHTSA investigation into premature rod bearing failures in Honda Odyssey and other models. However, my VIN is currently excluded from the recall. I request that NHTSA review this case as potential evidence that the recall should be expanded to include additional Odyssey vehicles.

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.
