Five days after getting back our car from the Honda dealership where they -??fixed-?? the two recalls all warning lights came on and not turn off. Steering, breaking, accelerating all are difficult. There were no issues prior to the dealership -??fixing-?? the recalls. The car was just at our mechanic for brakes and they check our engine, fluids etc every time. There were no prior issues.

While driving, the check engine light appeared and the vehicle began running rough and hesitating during acceleration. The engine experienced a noticeable loss of power, which created a dangerous situation in traffic and nearly caused an accident when attempting to accelerate with surrounding vehicles. The vehicle was taken to a Honda dealership for diagnosis. The dealership confirmed a failed fuel injector on cylinder number four and a catalyst efficiency fault code (P0420). The dealership explained that the failed injector may have caused improper fuel delivery and contributed to damage to the catalytic converter. The dealer also indicated that similar fuel injector failures are addressed in Honda Service Bulletin 21-010 for this model year. However, my vehicle was not included in the VIN range covered by the bulletin even though it is a 2019 model and uses the same fuel injector part number referenced in the bulletin. The issue was confirmed by an authorized Honda dealership and the recommended repair was replacement of the fuel injector kit and catalytic converter. Honda corporate declined to fully cover the repair costs despite the similarity to the known issue described in the service bulletin. This engine malfunction created a loss of power while driving, which could present a safety hazard in traffic.

My 2019 Honda Odyssey is currently diagnosed with a connecting rod bearing failure, which matches the safety defect in NHTSA Recall 23V-751. While my VIN is excluded, I am reporting this as part of the NHTSA Investigation PE25-008. For several months leading up to the failure, I noticed a faint, repetitive knocking sound coming from under the hood. During my regular service visits to authorized Honda dealerships (including a visit in December 2025 at approximately 80,000 miles), I mentioned these unusual noises and asked the technicians to verify the vehicle's safety. On at least one occasion, repairs were made to the steering system to address noises, but the engine knocking persisted and eventually worsened until the rod bearing failure was confirmed in January 2026. This defect presents a serious risk of sudden engine seizure and loss of motive power at highway speeds.

Our 2019 Honda Odyssey EX-L was our primary family vehicle. We conducted all routine maintenance as required by Honda, including transmission fluid exchange. Our vehicle experienced rough shifting consistently and at 102,000 miles experienced a total failure in the transmission dog clutch, with Emissions lighting also being present. Vehicle required a tow to Honda and was cited" internal failure in the transmission. The confirmed related DTC's are P0841: Transmission fluid pressure sensor/switch A circuit range/performance; P0844: Dog Clutch malfunction; P0170A: Dog Clutch Abnormal operation. Parts $:5,736.73/Labor $2,385 plus fluids and freight. We were not aware Honda used the ZF transmission during this year model and experiencing rough shifting up to 102,000 miles which prompted our investigation. Thankfully, the car was parked however, had this been while on the road, this would have presented a major safety and risk to our family and others. This has set our family back quite a bit as we have to replace the transmission and cannot guarantee the new one won't provide similar issues. Honda denied our good-will assistance request. We bought a Honda under the assumption it was a reliable brand. We will never buy Honda nor recommend again. Terrible experience.

"Emissions system problem" engine warning light has been on for quite some time. I know there is a service bulletin related to this issue, but my VIN is not covered. There are also several other warning lights that occasionally pop up, and my Honda dealer believes these are all related to the initial warning light. They mentioned that sometimes these systems start shutting down so the vehicle runs properly. Recently I received "transmission system prolem" (in conjunction with the slew of warning lights I have frequently been getting). No apparent issues until recently when I was driving on the interstate. The engine started to become very loud and when I looked at the RPMs it was very high, over 5,000 RPMs. The car wasn't shifting out of first gear at 55MPH. I immediately slowed down and got off the interstate as soon as possible. After arriving home, we unhooked the battery, re-installed, and all of the warning lights were gone. Again, the Honda dealer believes all of these issues were realted to the "emissions system problem", which is part of a service bulletin that should be covered by warranty extension. I beleive my VIN should be included, and the recent transmission system problem which happened on the interstate was very dangerous and could have ended very badly, had I not been in tune with what was happening.

Vehicle intermittently loses propulsion during acceleration when merging. Engine RPM remains low despite throttle input. After a delay, transmission re-engages abruptly with a metallic scraping noise. This creates unsafe merging conditions. This happened today, 2/14/2026 in 4 instances in the same trip. It has also occurred approximately 50 other times over the past six months when the mileage was as low as 66,100 miles.

Life-Threatening Acceleration Lag: The vehicle is experiencing severe power loss during critical driving moments, for example, while entering intersections or attempting to re-accelerate into moving traffic. When I attempt to speed up, the engine fails to respond initially, leaving the vehicle stranded in the path of cross-traffic. The engine finally engages only because I am forced to floor the accelerator pedal out of necessity, which then causes the tires to squeal when power eventually returns. Intermittent Starting Issues: The vehicle frequently fails to start smoothly on the first attempt; a known symptom associated with the fuel pump impeller deformation described in Recall 23V-858. VCM Shudder and Hesitation: I am experiencing the distinct vibration and rhythmic shudder associated with the Variable Cylinder Management system. This symptom is most prominent during deceleration or coasting; specifically, when I lift my foot off the accelerator without applying the brakes, the system triggers a noticeable shudder as it incorrectly manages cylinder engagement/deactivation. Suspected Catalytic Failure (Codes P0420/P0430): Both catalytic converters are exhibiting inefficiency codes simultaneously, which are highly atypical and occur well before the expected component lifespan. This clearly points to upstream defects. Specifically, the catalytic substrate has been poisoned by carbon and phosphorus deposits from the documented oil-burning defect and has suffered thermal damage due to the improper fuel mixtures caused by the defective high-pressure fuel pump (Recall 23V-858).

Service engine light has been lit up and it says -??emissions system problem-??. I have had it tested at the shop and it states code P219A (air-fuel ratio variation of cylinder [bank 1, rear bank) which I am told has a warranty extension from Honda for 10 years or 150k miles. I am told my VIN does not quality. If other 2019 Odyssey-??s have the same issue and qualify, why doesn-??t mine? The fuel injectors are clogging and failing way too early for 66k miles. This has been going on for around 6 months Safety concerns - Potential engine failure, reduced performance, and increased emissions

I am getting a failing fuel injector that is not covered in Hondas openTSB. I am unsure how it was determined that only VIN are covered when it is the same engine for all 18 &19s. Honda is denying work but reporting because many others are having same problem and not covered on an odyssey forum. I believe it is an issue with more than the VINs in the extension. Recommending that NYSB collect data on all odyssey and see the failures

On November 27, 2025, my 2019 Honda Odyssey experienced a sudden and catastrophic engine failure while traveling at highway speed. The vehicle had been serviced at an authorized Honda dealership the previous day (oil change and tire rotation), and the failure occurred approximately 55 miles after that service. While driving on the interstate, the engine abruptly lost power, expelled a large quantity of engine oil onto the roadway, and then caught fire in the engine compartment. The driver managed to pull over safely and extinguish the fire. This was a significant safety hazard to the driver, passengers, and surrounding motorists. The dealership later reported that the engine suffered internal mechanical failure involving broken connecting rods, which caused extensive engine damage and oil loss. I reviewed public information and discovered that certain Honda 3.5L V6 engines from similar model years have been recalled for internal engine defects that may lead to connecting-rod issues or catastrophic engine failure. However, my vehicle-??s VIN is not currently included in those recalls, despite experiencing a similar failure pattern. This incident involved: Sudden loss of engine power at highway speed Immediate oil loss onto the roadway Engine compartment fire Risk of collision or injury Given the severity of the incident and the similarities to known recalls for related engine failures, I am submitting this report to request that NHTSA review this event as part of potential broader safety concerns involving this engine family. The underlying cause should be evaluated to determine whether a defect or pattern exists that could affect additional vehicles not currently included in recall campaigns. No injuries occurred, but the incident posed a serious risk to life and traffic safety.

The engine was the component that failed. While accelerating, I first noticed a slight knocking sound. At steady speeds the noise went away, but during the same drive it became progressively more frequent until it occurred under all driving conditions. When stopped at a light to make a left turn, the vehicle shut off immediately as soon as I released the brakes. There were no warning lights, diagnostic messages, or prior symptoms before the failure. Because the vehicle lost all power in the middle of a multi-lane intersection, my family and I were stranded in the roadway for approximately 1.5 hours until a tow truck arrived. The vehicle could not be moved out of traffic. After towing, a retired mechanic who operates his own shop inspected the vehicle. He performed a brief, approximately 15-minute preliminary evaluation and reported that the engine is seized. Based on his initial observation (without engine teardown), he believes the cause may be a failed crankshaft bearing, but this has not been confirmed. No dealer or manufacturer inspection has been performed. Insurance declined involvement because mechanical failure is not covered. No police report was filed.

2019 Honda Odyssey (VIN: [XXX] ) - Fuel injector failure at 51,000 miles, November 2025. Cost: $1,260. KNOWN MANUFACTURING DEFECT: Honda Service Bulletins 20-100, 21-002, 22-002 acknowledge widespread fuel injector failures in 2018-2019 Odysseys caused by debris from manufacturing process. Honda extended warranty to 10 years/150,000 miles for certain VINs. My VIN excluded despite identical failure. EVIDENCE: (1) Same symptoms/codes as covered vehicles (2) Fuel pump replaced under recall same visit - proves manufacturing defects (3) Proper maintenance with receipts (4) Dealer admitted injectors shouldn't fail at this mileage (5) Hundreds of similar complaints online HONDA DENIED COVERAGE: American Honda denied goodwill because I don't have dealership service records. This makes no sense - manufacturing debris in injectors isn't caused by where you get oil changes. SAFETY ISSUE: Sudden power loss, multiple warning lights, stalling risk while driving. REQUEST: Investigate why Honda excludes certain VINs from warranty coverage for acknowledged manufacturing defect. Require expansion of coverage and reimbursement program. Pattern of defects (fuel pump recall + injector failure at 51k miles) indicates quality control problems. Thousands of owners affected.

We bought this van new and twice since owning it-once in 2019 at 5,418 miles and this month (November 2025) at 136,947 miles-we have been driving down the interstate with a van full of people, when without any previous warning, suddenly multiple warning lights come on all at once (the check engine light, the transmission light, the vehicle stability assist light, among others-what I have been told in LIMP mode) and the van becomes difficult to drive. The engine revs and the multiple warnings keep flashing. It has been extremely dangerous to be going at interstate speeds and suddenly thrown into a driving status where our speed is crippled to a slow pace and trying to get to an exit or shoulder without causing an accident. We have had to have the van towed both times in order to get it to a dealer to have it looked at and fixed. Both times we have been told by 2 different Honda dealership service departments that it was the rocker arm oil pressure switch and the most recent time (2025) we were told they had to also replace the rear spool valve to make the error codes go away. The code P2652 was a code that had to be cleared both times with the repairs that they made. In Nov. 2025 the dealer scanned the vehicle and found codes p0301, p0302, p0303, p0306 cylinder 1 2 3 and 6 misfires. They found code p2652 rocker arm pressure switch to be stuck on. They checked the circuit and found the wiring to be ok. They replaced the rocker arm pressure switch and rear of cylinder head problem did not change. Oil levels were where they should have been. They removed the rear rocker bridge and rear spool valve to inspect the rear spool valve and found the rear spool valve to be sticking causing the vehicle to be in constant vps. They installed a new rear spool valve and cleared codes. We do not have the components to be inspected.

I am writing to file a formal complaint regarding a serious engine failure on my 2019 Honda Odyssey, which experienced a rod bearing failure that has rendered the vehicle inoperable. This failure occurred despite the vehicle being properly maintained and driven under normal conditions. As a result of this engine failure, my Odyssey is currently parked and unusable, yet I am still required to make ongoing auto loan payments while I attempt to find a solution to cover the cost of repairs. This issue was first detected at 63,000 miles.

The power sliding door on the driver-??s side failed and will not open, even manually. The mechanism engages and stops after about an inch. This creates a significant safety risk because passengers cannot exit through the door in an emergency. This appears to be a widespread defect in 2018-?"2020 Honda Odyssey models. Repair cost is approximately $1,000. Honda needs to address this as a safety issue.
