2019 Honda Odyssey engine problems

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.

1- engine fully restart after auto idle feature engaged. 2- this has happened multiple times over the past couple of weeks. With one instance- it attempted to restart when I removed my foot from the break. I was on a downward incline leaving a parking lot, pulling in to a busy road. My car rolled in to traffic and I was unable to start the engine. I had a disabled vehicle, in traffic. The second time, I was also at a slight downward incline at a stop light in a less than desirable part of town. When my foot was removed from the brake, the engine would not engage and car would not move. I was blocking a lane of travel. Multiple warning light occurred, with a written warning that stated “transmission problem. Apply parking break when parked.”

I am reporting a severe engine issue on my 2019 Honda Odyssey that matches the exact failure profile of the federal safety agency Recall 23V‑751 and the ongoing investigation PE25008 / RQ24-013. While driving, the vehicle randomly began experiencing a loud, progressive metallic knocking and ticking noise from the engine, sometimes it was a squeal, the engine stalled while in motion and wouldn't drive anymore. This presents a severe safety hazard, as an unexpected engine stall or failure while driving increases the risk of a crash. My VIN currently shows as "excluded" from Recall 23V‑751. However, given that this vehicle has the exact same 3.5L V6 engine and is exhibiting the textbook symptoms of premature connecting rod bearing wear and crankshaft-related failure, I request that the federal safety agency review this case to expand the recall parameters to include my vehicle batch.

My wife was driving our young daughters and the vehicle had multiple warning lights come on. then several messages stated transmission drive unavailable. then the vehicle stopped moving and stalled in a busy street. it would re-start but was idling at 3000rpm. however it would not move from where it died. it had to be towed to the Honda dealer. It was a very dangerous situation because it went from a check engine light to a dead vehicle in 30 seconds. very unsafe!

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.

When I am sitting at a traffic light and the auto engine idle stop gauges it very frequently completely shuts off the engine and will not restart. I will hit the power button to try and turn the vehicle back on, but it won’t work. I have to put the car into park, completely turn off the car battery, open the car door, while sitting in the middle of traffic, and then shut the car door and restart the car. If I do not open the car door, I cannot restart the car. I have taken this into Honda twice to have an evaluated and they “cannot find“ the problem despite their being a bulletin out specifically about this problem. It is now shutting off on me three and four times in a single trip. I was almost in an accident trying to restart my car when a light turned green and I couldn’t get my vehicle to restart as all the cars around me went. This has been an ongoing problem for years.

I'm filing a formal safety complaint regarding my 2019 Honda Odyssey, VIN [XXX], & requesting an engineering-level review by American Honda. I've brought this vehicle to an authorized Honda dealer numerous times for recurring & increasingly serious electrical, engine/power-loss, & transmission problems. Despite thousands of dollars in repairs, the problems continue. The vehicle has unexpectedly shut off/lost power; the power sliding doors have failed & required manual opening; low-battery warnings have appeared; & the radio/infotainment system repeatedly loses power and resets. I have photographs showing the message: “Anti Theft System–This system has lost power.” More seriously, the vehicle has malfunctioned in Park, Reverse, while shifting into Drive, & while turning. Most recently, the transmission would not engage properly and the vehicle had to be shut off and restarted multiple times before it would go into Drive. Delray Honda documented this transmission failure/no-drive incident on its August 2026 repair order. In May 2026, I brought the vehicle to Delray Honda for a Check Engine Management System warning. Repairs were performed, but the warning returned within days. Delray Honda then replaced the power distribution module, costing me approximately $2,000. I've spent thousands more dollars addressing these recurring problems without resolution. I understand Honda/the federal safety agency Recall 19V‑299 involved certain 2018–2019 Odysseys and a loss of power to the Transmission Control Unit. My Odyssey appears to have been manufactured around the time of those Hondas that were covered by that recall. I'm not claiming without diagnosis that the defect is identical, but the similarity of the symptoms warrants an urgent investigation. I request that Honda open a formal safety case, review my complete service history, DTCs and TCM/PCM data, determine whether my vehicle has the same or a related defect, and review my prior repair costs for reimbursement. Thank you. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT

When driving the vehicle it always has a lag in acceleration when pressing on the gas pedal. There are numerous times I can press the gas pedal and the car will not move. I've taken back to the dealer to see what their service department says.

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.
