2019 Honda Odyssey Engine Problems

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 NHTSA 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.

I was driving on a highway and all of a sudden, I see three warnings appearing on my dashboard - "Emission System Problem", "Blind Spot Info System Problem", "Transmission System Problem". I continued driving but then my vehicle started behaving weird. It started shaking while driving. Luckily, I was close to my exit and l somehow managed to take the exit but I wasn't able to move forward when the road was uphill. I somehow managed to park next to a house and walked back home. It was a really scare drive from the time those errors showed up to when I parked. This all happened few minutes ago. Here below is a thread where I can see others having this problem.

The vehicle is experiencing a dangerous hesitation during acceleration at low speeds, immediately followed by a sudden, violent forward lunging motion. When attempting to accelerate from a complete stop, or when rolling at low speeds (such as yielding at a roundabout, turning through an intersection, or merging into slow-moving traffic), the vehicle suffers from a distinct **lag or complete failure to accelerate** for several critical seconds. In an attempt to get the vehicle to move out of harm's way, the driver naturally applies more pressure to the gas pedal. The vehicle's transmission then randomly responds after a few seconds with a violent lunge forward, spinning the tires and causing the vehicle to surge unpredictably. This unpredictable behavior creates an immediate and severe safety risk to the occupants of my vehicle and others on the road: 1. Intersection Collisions: The sudden lag leaves the vehicle stranded in oncoming traffic during turns, while the subsequent lunge threatens to overshoot the intended lane. 2. Pedestrian Hazards: The sudden, uncontrollable lunging makes low-speed maneuvers in school zones, crosswalks, and parking lots incredibly hazardous. 3. Drivers behind behind me do not expect a vehicle to suddenly stop accelerating after it has begun to move forward. I have taken the vehicle to the dealership we're we were able to reproduce the issue and Honda would not offer a fix. I thought I was going to get my entire family killed the other day when I pulled out at a stop the van hesitated in the middle of the highway for a few seconds before lunging forward. This is an intermittent issueand the severity varies each time, but is commonly cited online.

On May 2nd, we drove our 2019 Honda Odyssey XL-E to church, and as soon as we pulled into the parking lot, we started to see smoke coming from our front hood. We exited the car. Within 30 seconds, the car then went into flames, and exploded and the car is now unsalvageable. When I went online, it seems like this is a common occurrence with these Honda Odysseys. There were no warming lamps, messages, or lights that would have alerted me that something this serious would occur. We have taken our care to Honda for years for regular maintenance. We don't take it to any independent shops. Strictly to Honda for years. The most recent checkup/service was performed on February 11, 2026 where they performed the following services which they had recommended. 1) Oil Change 2)Engine coolant flush with conditioner 3)Transmission fluid change: 4) wheel alignment 5)Fuel tank additive, throttle body service, and injector. This is serious safety event and our family and children could have been killed in this accident. We have pictures, videos, police report, and the car has been taken to a salvage yard. We have filed a claim with State Farm.

[Incident Description & Manufacturer's Bad Faith] On April 6, 2026, an authorized Honda dealership (McConnell Honda in Montgomery, AL) diagnosed my vehicle (2019 Honda Odyssey EX-L, 143,097 miles) with DTC P219A (Rec replacing fuel injector set and fuel feed pipe at this time), requiring a fuel injector replacement. This exact mechanical failure is documented in Honda’s official Service Bulletin 21-010. The bulletin acknowledges that defective fuel injectors can cause engine misfires, loss of motive power, and engine stalling while driving. These conditions present an immediate and severe safety hazard. Honda established a 150,000-mile warranty extension limit for this defect in TSB 21-010. My vehicle has 143,097 miles and is well within this limit. However, American Honda Corporation has arbitrarily refused to repair the vehicle. Furthermore, on April 21, 2026, the assigned Honda Case Manager left a voicemail officially denying the repair. He explicitly refused my repeated requests to provide this denial in writing. In the voicemail, he falsely stated that my vehicle at 143,000 miles is "well outside the range" for assistance, directly contradicting Honda's own written 150,000-mile bulletin. Please review the attached documents, including the official dealership diagnostic report (DTC P219A), the repair estimate, and a copy of TSB 21-010. I have also secured the audio recording of the case manager's voicemail to prove their bad faith. Honda is knowingly leaving a dangerous vehicle with a confirmed, documented fuel system defect on the road, while actively providing false information to the consumer to avoid repair costs. I strongly request the NHTSA to investigate Honda's deceptive and dangerous practice.

I was driving to work on April 7th, 2026 and parked the vehicle at my company parking lot. Prior to parking, I noticed unusual smell and then parked the vehicle. I parked the vehicle around 8.10 am and I got the call from my facilities manager around 8.30-8.40 am that my car caught on fire and by that time I noticed Houston Fire Department extinguishing the fire. There were no check engine sign and this vehicle is a brand new vehicle when I purchased. Though there is no recall associated with my VIN #, the fire issue is similar to recalls for 2019 Honda Odysey. The recall numbers are 23V-751( Engine Fire Recall) & 20V-066 ( Electrical Wiring fire Recall)

There is a delay in acceleration. When at stop light, stop sign, or moving forward after backing out of driveway, we are experiencing a 2-4 second delay in acceleration after putting pressure on the gas pedal. This has caused scary incidents when trying to turn left at stop lights or stop signs. When talking to Honda dealers, they have not been helpful in determining the cause of this.

Multiple safety systems on my 2019 Honda Odyssey Elite have simultaneously failed, including LKAS, ACC, Collision Mitigation Braking System, Auto High-Beam Headlights, and other driver-assist features. The dashboard displays warnings for nearly every safety-related system, and the vehicle disables these features without warning. **Detailed Description of the Problem:** Whenever I start my vehicle, multiple error messages are displayed related to the Lane Keeping Assist System (LKAS), Adaptive Cruise Control (ACC), Collision Mitigation Braking System (CMBS), Road Departure Mitigation, Auto Headlights, and other safety features. These warnings appear together and persist even after restarting the vehicle. Apparently, this issue is widespread among 2018–2020 Honda Odyssey owners, with many reporting the same cluster of system failures. The problem appears to be related to a malfunction in the vehicle’s electrical system, sensors/ cameras, or control modules. In my case, the failures occur without any external damage, weather event, or driver action that would explain the sudden loss of safety functionality. When these systems fail, the vehicle disables critical safety features such as automatic emergency braking, lane keeping, adaptive cruise control, and automatic headlights. This creates a significant safety risk, especially at highway speeds or in low‑visibility conditions. **Frequency:** The issue occurs whenever the vehicle is started, affecting my driving everyday.

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.
