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.
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.
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.
I bought a 2018 Honda Odyssey ex-l with around 80,000 miles. Not long after, I noticed a loud engine vibration 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 or messages — just a sudden failure. 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, often between 70,000–90,000 miles. 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 was forced to pay $1,273 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.
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.
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 interstate 95 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).
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.
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.
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.
Engine shut down driving on [xxx] in colorado just past [xxx] (xxx). Had to pull over and car towed to shop that found engine would not start, locked and could not rotate by hand.

Vehicle failed to restart after auto shut off engaged at red light. I was unable to move and had to turn vehicle off completely and restart.
Honda has issued a recall for the 2018-2019 Honda Odyssey vehicles and certain Acura, pilot, and ridgeline vehicles due to a manufacturing error on the connecting rod bearing in the engine, which can damage the engine. Might also be in service bulletin 24-003. This recall, identified as #23v751000, was announced on November 12, 2023. My VIN is not currently covered by this recall yet I am experiencing the exact same symptoms. I have 6 children that a transport in the vehicle daily and we are moving from minnesota to georgia soon. I cannot afford to pay for the repairs of this manufacturer defect out of pocket. Local Honda dealership estimates over $10,000 for this repair! I am now going to an automotive service center to see if they have a more affordable solution. It isn't looking good. I am still driving this vehicle, but the knocking coming from the engine compartment is getting louder and louder and I fear the engine could seize while driving on the road with my children in the vehicle. I also reported this to Honda corporate on March 28, 2025.

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.
See attached document for complaint.
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.
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.
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. We took the vehicle to dealer ship and they mentioned that transmission failure where vehicle just two weeks ago at the dealership for another repair and inspection report didn't specify anything about the transmission.
Did not control speed sometime up and down engine.
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.
Over a year ago, my vehicles engine began ticking. On 12/14/2024, while driving the vehicle, it developed a rod knock, went into a limp mode and was towed back to our house. I eventually took the vehicle to Honda in beaumont, TX where they did an inspection of the vehicle and verbally told me it was the crankshaft, but would not provide me any documentation stating that. According to the lady at the desk, the service tech had never seen or heard of an issue like this in these vans. I was quoted almost $10,000 to replace the engine with a salvage yard engine with almost as many miles on it. I knew prior to taking it to Honda that there was a recall that did not cover my vehicle regarding this same issue. The vehicle is still parked at my house being started occasionally to keep battery charged.
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.
Code p219b. I feel this vehicle falls into the same fuel injector issue as other 2018 Honda Odyssey. Bulletin 20-100, 21-010.
The check engine light on my 2018 Honda Odyssey has been on since January 2024. We took it to the dealer (music city Honda - mt. Juliet, TN) and they claimed the 02 sensors were bad. We paid $500 to have these replaced, but the light came back on. We then received the recall for the fuel pump module. We have tried twice since may 2024 to get the part under recall replaced but have been told both times that the part is unavailable. The dealer claimed that we could bring it in but if the issue is not determined to be related to the recall, we will have the pay the diagnostic fee. Not only is my check engine light on (it says emissions system problem), but my car stalls while driving. This poses a significant safety risk for myself and my family, and Honda is refusing to do their part to remedy the issue at no cost.
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.
Had about 4 incidences that van completely stalled while driving when coming to a stop. About a week later, was driving the van at approximately 6o mph when it completely shut down, had to pull over immediately to get off road. Came to a fast stop. Was thankful no other cars were behind us when it happened, feel they would have hit us as the vehicle shut down so quickly. There were no warning lamps or messages indicating any issues. My husband changes the oil/services it according to the manufacturer guidance. Was told by the local mechanic the engine is locked up, would need replaced. Called Honda to report, and since we do not service it at a Honda dealership, they would not assist.
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 driving approximately 35 mph, the engine made an abnormal knocking sound. The vehicle was taken to the dealer, where it was diagnosed that the timing belt had failed and needed to be replaced. The timing belt was replaced; however, the failure persisted. The dealer determined that the connecting rod bearing in the engine needed to be replaced. The dealer informed the contact that the engine needed to be taken apart to perform the repair. The vehicle was not repaired due to the cost. The contact related the failure to NHTSA campaign number: 23v751000(engine and engine cooling). The manufacturer was notified of the failure and informed the contact that the repair could not be covered under the recall because the VIN was not included. The failure mileage was approximately 86,470.
