Back in the fall/winner of 2024 (could have been 2025) my Honda Odyssey had a recall for a low pressure fuel pump. However, Honda and many other dealers were dealing with hundreds of thousands of recalls, and we’re only recalling the vehicles with actual symptoms. My vehicle was hesitating and experiencing sudden loss of power during acceleration therefore Honda agreed to repair my vehicle. Everything seemed to work fine after that with no issues, but approximately three months later, I was having issues with my vehicle and brought it into my Mechanic, to find out that my high-pressure fuel pump was not working properly. Upon further investigation, I found out that a bad low-pressure fuel pump starves the high-pressure fuel pump (HPFP) of required volume. This causes the HPFP to work far beyond its design limits to build pressure, leading to cavitation (vapor bubbles damaging internal components), overheating, and premature mechanical wear from metal-on-metal friction. When I dug a little deeper, I found out that many Honda owners were dealing with failing high-pressure fuel pumps after having their low pressure fuel pump recall repairs completed. Many in which were in a similar timeframe to mine. Honda offered me no good merit assistance and stated that unfortunately, I would be liable for the entire cost of the repair. It is more than obvious that the failing of my low pressure fuel pump impacted the performance and workload of my high-pressure fuel pump, causing it to fail, which I believe Honda should be liable for replacing. Please look further into this matter to help others like me that had their low pressure fuel pump recall performed, and shortly after needed to replace their high-pressure fuel pump at their own costly expense.

I own a 2018 Honda Odyssey EX-L (VIN [XXX]). The vehicle experienced a sudden loss of power and entered limp mode, with multiple safety and driver-assistance systems shutting down at once (adaptive cruise, braking assist, lane/road departure mitigation, EPS, etc.). A Honda dealer (Allen Honda, College Station, TX) retrieved DTC P0369 and documented that the front camshaft is worn and has thrust forward, contacting the camshaft position (CMP/TDC) sensor and damaging the thrust plate. The dealer is recommending an internal engine repair costing several thousand dollars. I am very concerned because Honda has already acknowledged serious engine defects in this same J35 V6 family under Recall 23V751 (connecting rod bearing wear leading to engine damage and stall) for 2018–2019 Odyssey, yet my dealer states my VIN is “not part of the recall” and that this is a “separate issue.” In practice, I am seeing a major internal engine failure that causes sudden derate and disables multiple safety systems, but I am being told there is no recall coverage or assistance simply because my individual VIN falls outside Honda’s current recall production range. I am requesting that the federal safety agency review this incident as a potential recall exclusion problem: owners with the same engine family and serious internal failures are being denied recall coverage on a technical VIN cutoff, even though the safety consequence—loss of power and shutdown of critical safety systems while driving—is similar to the failures already recognized under Recall 23V751 and the ongoing engine defect investigation. I believe this situation may warrant expansion of existing recall coverage or a new recall campaign for currently excluded VINs like mine, and reimbursement for owners who have already paid for these repairs.

When driving at speed, the car will lose power, and you cannot go anywhere until the transmission reengages Also when starting out there is a hesitation sometimes very dangerous at intersections

While driving down an interstate going approximately 70 mph, the engine, all of a sudden started losing power and showing a check engine light. I immediately pulled over to a safe location. Check the oil which appeared okay and called a tow truck. Bring my vehicle to a local shop. The shop did some inspections and found that there was some failures on the connecting rods. Nothing else has been done at this point

Summary: Engine seized due to internal bearing failure with metal shavings found in oil filter. Full Description: My 2018 Honda Odyssey experienced a sudden engine failure around 116,500 miles. The dealer confirmed the engine is seized and showed significant metal shavings in the oil filter and pan. I have performed all maintenance according to Honda’s recommended schedule using the correct oil and filters. Honda corporate denied assistance based solely on mileage, even though this issue matches symptoms described in current the federal safety agency investigation PE25-001 (connecting rod bearing failure in Honda 3.5L V6 engines). There were no prior warnings other than a brief check-engine light and rough running before the engine locked up. The vehicle was in motion at the time and could have caused a hazardous stall, serious injury, or death. Given that Honda has issued recalls for similar rod bearing defects in other model years (2015–2020) and this failure mode presents a clear safety risk (loss of power, engine seizure), I request the federal safety agency include my case in its investigation and compel Honda to extend recall coverage to 2018 Odyssey owners. I can provide dealer diagnostic reports, photos of the oil filter debris, and all maintenance records if needed.

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.

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 the federal safety agency investigation into premature rod bearing failures in Honda Odyssey and other models. However, my VIN is currently excluded from the recall. I request that the federal safety agency review this case as potential evidence that the recall should be expanded to include additional Odyssey vehicles.

The transmission is very jerky and has completely lost power before. It has refused to shift and stalled in the middle of the road. It is very scary.
