On this 2018 Honda Odyssey, at 93000 miles, an abnormal noise started to occur under acceleration. Dealer diagnostic indicated the noise is coming from the bottom end of the engine, likely from the rod bearings. The dealer indicated that this specific VIN number is not included in the current Honda recall, however is exhibiting same symptoms.

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.

There is a major safety issue that has happened a few times now. As I come to a stop, or come out of a stop, the engine stutters and completely shuts off. All electronics stop too. Immediately there is a message flashing -??right sliding door problem.-?? I have to put my foot on the brake and restart the engine to get going again. This recently happened as the red light turned green, and a car almost slammed into me from behind.

I took my 2018 Honda Odyssey to the dealership for a fuel pump recall repair. The next day, the engine warning light turned on, and I heard a loud abnormal noise from the high-pressure fuel pump.I scheduled an immediate service appointment. The dealer charged me $230 for a diagnostic but claimed no fault or error code was found. They turned off the warning light without explaining why it was triggered.The abnormal noise from the high-pressure fuel pump persisted, and the dealer recommended replacing the high-pressure fuel pump for $1,942.78 while denying any connection to the recall repair. Component/System That Failed: High-Pressure Fuel Pump Engine Management System How Was Safety Put at Risk" A fuel system failure can cause engine stalling, leading to sudden loss of power while driving and an increased risk of a crash. Has the Problem Been Confirmed by a Dealer? Yes. The dealership acknowledged an abnormal noise from the high-pressure fuel pump but denied any connection to the recall. They only reported a DCA-8000 code, which is not a standard fuel system error code. Has the Vehicle Been Inspected by the Manufacturer? Yes. The dealership inspected the vehicle but refused to take responsibility. Honda Corporate was also contacted, but they denied warranty coverage. Any Warning Lamps or Symptoms Before the Failure" No prior issues before the recall repair. The engine warning light turned on the next day, and the abnormal noise from the high-pressure fuel pump began immediately after. Why This Needs to Be Investigated: The issue began right after the recall service, suggesting a possible defect. The dealer charged me $230 but failed to explain the warning light activation. If other vehicles experience this, it may indicate a recall defect. A fuel system failure can create serious safety risks for drivers and passengers. NHTSA must investigate whether the recall service contributed to high-pressure fuel pump failures, as this could pose a significant safety hazard.

The contact owns a 2018 Honda Odyssey. The contact stated while driving 70 MPH, the vehicle lost motive power and failed to accelerate as intended. The check engine warning light was illuminated. The vehicle was then steered over to the side of the road and restarted; however, the failure persisted. Additionally, the contact observed a knocking sound coming from the engine compartment. The vehicle was taken to the residence. The vehicle was then taken to a dealer where it was diagnosed that the control rod had fractured, and the engine needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 144,000.

2018 Honda Odyssey engine failure due to a 'spun' connecting rod bearing. This is a known issue with this particular make and model and should be considered in the recall for these vehicles.

- Portland, OR, USA

The vehicle has recently and suddenly developed a loud engine knocking sound which sounds like an engine bottom-end knock (crankshaft or connecting rod). The sound is dependent upon engine RPM and is most noticeable at low RPM and when the engine is warm. The knocking sound is severe for the first 1-2 seconds on cold engine start, until oil pressure is developed. There are two known incidents believed to be caused by this issue: 1. While driving on a public highway with a 75 MPH speed limit, the engine knock became severe and the check engine light began flashing. The car would not accelerate, and once speed was reduced it would not accelerate at all and "limped" home at much-reduced speed. Prevailing traffic had to take action to avoid colliding from behind. 2. While driving up a very slight incline on a public highway with a 65 MPH speed limit, the engine knock became severe and the check engine light began flashing. The engine was unable to produce power and struggled to climb the hill at around 33 MPH with prevailing traffic coming up quickly and swerving to avoid colliding. The vehicle "limped" home again. The problem has been confirmed by an independent service center specializing in Honda and Acura vehicles, and confirmed that the knocking sound does indeed sound like a connecting rod and referred me to Honda service bulletin 23-097. I called American Honda to inquire as to whether my vehicle's VIN qualifies for the associated recall, and they said the vehicle does NOT qualify, and that it was a very narrow range of VINs which do qualify. The vehicle has not yet been inspected by the manufacturer, police, or insurance, only the independent service center who did NOT open the engine bottom end for inspection, only listened and did non-invasive troubleshooting before referring me to Honda. Please add this to the Office of Defects Investigation's investigation RQ24013

Emission error code which is part of recalls due to Fuel pump and suddenly check Egin light came on and vehicle couldn't shift from Park Mode to Drive Mode.

Did not control speed sometime up and down engine.

- San Jose, CA, USA

The engine failed without prior indication. The dealer says the engine is destroyed and needs to be replaced. Once the engine stopped working the vehicle would not go into neutral and was immovable preventing the vehicle from being moved to a safe location. The dash had a message that said the engine must be running to shift to neutral but the engine was blown. The owners manual has no solution to put the vehicle in neutral with an inoperable engine.

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.

My 2018 Honda Odyssey stalls or hesitates when I go from a stop to accelerate. The vehicle will lose all power for 3-6 seconds and when the engine catches up to the pedal, the vehicle accelerates hard, spinning the tires and jerking the vehicle. I've had the vehicle inspected at my local Honda dealership and they've said the vehicle has no open recalls. This includes the fuel pump recall and the engine recall, neither recall has been issued for my vehicle. The results of the inspection was the technician explaining that "the vehicle just does that." My vehicle has not produced any warning lamps for the engine. My vehicle has produced several warnings lamps and warning messages on the infotainment screen about the side doors being open. I've had several instances where the door will not close and or will not open properly.

Engine has been -??hiccuping-?? for a few months and making a knocking sound. Brought it to Honda on 3 separate occasions and they -??could not replicate-?? the sound. And said it-??s normal. I-??ve had 2 non Honda mechanics look at it and they agree it sounds like a rod knock and engine failure is going to happen sooner rather than later.

During the hurricane Milton evacuation my wife and our 3 children suddenly lost power on I75 North in the dark and had to pull to the side of the road with speeding cars flying by in near pitch black. we later discovered that the control rod in the engine is broken according to a Honda dealership and we would need a new engine. The dealership said it is very strange for this to happen with how well it appears to be maintained and that there was a previouse recall on the 2018 and 2019 Honda Odysseys and mine might need to be included however upon speaking with Honda they said there was nothing they could do. Dealership quoted me $9,100 for new engine.

While driving down the interstate, the engine started to make a loud squealing noise. I pulled over to investigate. Not being a mechanic, I couldn't determine anything. I attempted to start going again and the engine had no power. I was barely able to get it off the highway and we called for help. In the van were me, my wife, and daughter. It was scary with cars and semitrucks driving past us at high speeds. I was concerned. We were able to get the van towed after several hours of waiting. It was a hot day and I had a tick on me while waiting. The van took over a month to repair. The dealership confirmed the cause of the engine failure as the cylinder #2 connecting rod bearing. There were no warning lights when we pulled over the first time. When we started going, the check engine light came on.

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.

Either the engine or something else keeps failing and i completely lose power. I got the car towed back to my house. The car starts but a lot of the time it will keep shutting down while I'm on the road. I went to the dealership twice to get it checked out and they say that they do not know what the problem is and can not guarantee that they can fix the issue.
