general problems of the 2018 Honda Odyssey - part 2

Short summary (for “briefly describe the problem”) sudden catastrophic engine failure — engine threw a rod at ~85,000 miles despite proper maintenance and fluid levels. Detailed description (for “provide details of the incident”) while driving, the vehicle began making a loud noise similar to a helicopter taking off. I immediately took it to a certified mechanic, who diagnosed that the engine had “thrown a rod,” requiring a full engine replacement. The vehicle has approximately 90,000 miles, has been regularly serviced per manufacturer recommendations, and all fluids were at proper levels at the time of failure. There were no warning lights or prior signs of mechanical issues. My mechanic and I contacted Honda to determine if NHTSA recall 23v-751 applied to my vehicle; Honda confirmed it did not. Despite this, the symptoms appear consistent with known defects covered by that recall. Honda has declined to provide assistance or repair. The sudden and complete engine failure under normal driving conditions, despite proper maintenance, suggests a potential manufacturing or design defect that poses a serious safety risk.

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

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. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

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.

The throttle can loose power at stop and then suddenly engine picks up the throttle which not normal and this is not maintenance issue as service station and Honda does not confirm the behavior a defect or a problem. This is very concerning.

Engine knock due to a spun bearing.

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. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The engine stalled while driving the 2018 Honda Odyssey van on the freeway. It happened while cruising on the freeway. Engine suddenly locked out/stalled after a loud 'thug' sound. The situation posed a high safety risk to the occupants. Luckily no vehicular accident occurred. The dealer checked it out and confirmed it is an engine problem. Their recommendation is to change the engine and charged the cost to the owner. Dealer said the problem is not covered by recall. Dealer will not specify the engine problem unless the engine is opened for inspection. There were no warning lamps and messages of the problem prior to the failure.

I have maintained 2018 Honda Odyssey regularly, getting it serviced when or before it was due. A month ago (at 90k) miles, we started to hear a noise in the engine. I took it to Honda and they said that I need an entirely new (rebuilt) engine. I did see there was a safety recall report 23v-751 regarding crank pins that were produced out of specification. This did cover some 2018 Honda engines, but my VIN was not one of them. Is there any possibility that this deffect could have effected other Honda engines of the same year? my engine should not be failing at 7 years and 90k miles. Currently the vehicle is not being driven until we figure out the best course of action.

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.

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. They suspect timing may have jumped causing major internal damage to engine, possibly bent valves. Hole found in side of engine block thought to be from cap or other component breaking off. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

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.

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.

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.
