2019 Honda Odyssey engine problems

“The contact owns a 2019 Honda Odyssey. The contact stated that the vehicle was serviced under Technical Service Bulletin: 23-008; however, the vehicle experienced the failure stated in the TSB. The contact stated that while driving 10 MPH, the vehicle lost automotive power. The vehicle was towed to the dealer to be diagnosed, and the contact was informed that the failure was not duplicated. The manufacturer was notified of the failure. The failure mileage was 94,800.”

“I am reporting a severe engine issue on my 2019 Honda Odyssey that matches the exact failure profile of NHTSA 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 NHTSA 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…”

“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…”
