2019 Honda Odyssey: engine failure

Filed Nov 7, 2026 · Engine · CA

I am reporting a serious premature engine failure in my 2019 Honda Odyssey EX-L at approximately 88,000 miles. The vehicle has its original factory-installed engine and has been regularly maintained, including routine oil changes. While driving with my wife and young children, the vehicle experienced an engine stall and loss of power, creating a significant safety hazard. An unexpected loss of engine power while in traffic or at highway speeds puts the driver, passengers, and surrounding motorists at risk. Following the incident, a Honda dealership performed a diagnostic inspection and identified abnormal noise originating from the lower engine block, consistent with rod knock. Metal debris was also found in the engine oil, indicating significant internal engine damage. The dealership recommended engine block replacement, with an estimated repair cost of approximately $14,000. The vehicle was deemed unsafe to operate. Honda informed me that my VIN is not covered under the existing engine recall. However, I am aware of the federal safety agency Preliminary Evaluation PE25008, which investigates connecting rod bearing failures in certain Honda and Acura vehicles, including 2018–2020 Honda Odyssey models. Given my vehicle's model year, original engine, internal engine damage, and loss of power while driving, I believe this incident warrants investigation in connection with PE25008. I am requesting that the federal safety agency review this failure, determine whether it is related to the connecting rod bearing issues under investigation, and evaluate whether additional vehicles excluded from the existing recall may be affected by the same safety defect. I can provide dealership diagnostic findings, maintenance records, photographs, videos, and repair estimates.

Vehicle began to misfire on cylinder 3. As the issue continued more cylinders stared to misfire. Next was number 6, then 2 increased up the engine. Air fuel ratio was 1.6. Assuming it was fuel/air/electrical in nature, the spark plugs, and fuel injector were changed and air intake and upper valves were cleaned of carbon build up. All gaskets replaced by new. Discovered and replaced a bad egr valve. Last codes that the car displayed before towing to dealer were many misfire codes and 2 engine/transmission communication errors. Dealer shop discovered air fuel ratio of 1.35 and checked all work before. Discovered fuel pooling and some shiny areas in the engine from scoping it. Decided that if was a bad engine with internal failure and transmission. Quoted me $17000 (about the same value as the vehicle if it was jn very good condition) for a new engine and transmission or $6800 for a used engine alone at risk of replacing transmission as well assuming communication errors do not go way or transmission fails further. I have called honda corporate my reference # 16624114. I requested goodwill repair due to recalls and class action lawsuits related to connecting rods in engines of similar cars and model years. And transmissions recalls for similar cars and model years. Goodwill is unlikely but pending.

Hello, my 2019 Odyssey 3.5L V6 engine has a severe knocking noise/engine failure identical to Recall 23V‑751, but my VIN was excluded. The car has only 81,100 miles and started the knocking out of no where a week ago. I had an independant mechanic take a look at it and he said the same thing that it was the connecting rod bearing and the knock was coming from the engine. I dont think it is fair that I should be held liable for an engine repair that is a factory fault and just becuase my vin number is not inlcuded. The vehicles oil was also just changed at the dealership prior to the knock starting. Please have this strongly considered to have HONDA cover this repair.

The connecting rod bearings failed, resulting in engine damage. The failed bearings, crankshaft, and oil pan debris have been retained and are available for inspection on request. The vehicle developed a loud ticking noise from the engine. A Honda dealer initially diagnosed the noise as coming from the timing belt tensioner and replaced the timing belt and tensioner. The noise was unchanged after that repair. The dealer then traced the noise to the bottom end of the engine and performed a teardown on 07/16/2026, which confirmed connecting rod bearing failure with significant metallic debris throughout the oil pan. The dealer documented the failure with photographs. The engine is not driveable. The problem has therefore been confirmed by an authorized dealer through disassembly. The manufacturer has been notified but has not physically inspected the engine. There has been no police or insurance involvement. Warning symptoms: an audible ticking noise from the engine was the only symptom. No warning lamps, dashboard messages, or other indications appeared at any point before or during the failure. Safety: this failure mode is the subject of the federal safety agency Preliminary Evaluation PE25008, opened 08/20/2025, covering connecting rod bearing failures leading to complete engine failure in the 3.5L V6, including MY2018-2020 Odyssey. It is also the failure mode described in Recall 23V‑751, which states that engine failure may cause loss of motive power and increase the risk of crash and fire. My vehicle falls outside that recall's build range and the manufacturer has declined coverage on that basis. Had the bearing seized while driving rather than being found during shop diagnosis, the engine could have lost power or stalled without warning. This vehicle carries family passengers on highways. No crash, fire, or injury occurred.

The vehicle engine developed a rod knock at around 105,000 miles. Failing connecting rod bearing(s) has been diagnosed as the source of the sound by several different mechanics independently, including the Honda dealership, and engine replacement has been recommended. This first occurred while I was away for an extended period on military orders. My wife, not realizing what the sound was, continued driving on it for 1-2 weeks. Fortunately, no accident occurred, but at any moment the engine could have seized, causing serious bodily harm or death. Leading up to this issue, there had never been any check engine lights, low oil or low oil pressure warnings, or any such notifications that this issue was developing. Oil changes were performed regularly without any concerning oil quality findings. There is a known connecting rod/bearing safety recall involving my make, model, year of vehicle, but Honda is telling me the manufacturing date is not applicable. Despite my formal requests, Honda has been unwilling to acknowledge and help rectify the issue. I submit that the defect in manufacturing is more widespread than they are owning up to.

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
