general problems of the 2019 Honda Odyssey - part 2

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).

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.

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. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

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.

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.

While driving on the interstate the engine rod blew causing the motor to blow up and sustain a hole. This was confirmed by a Honda dealership during a video inspection. Several lights on the dashboard showed up shortly before the motor expired.

The contact owns a 2019 Honda Odyssey. The contact stated while driving approximately 30 mph, the check engine warning light illuminated. The contact stated that the warning light was intermittently illuminated, and the vehicle had started idling rough. The contact stated that the vehicle was not diagnosed or repaired by a dealer or an independent mechanic. The contact stated that upon scanning the vehicle with a vehicle scanner, the contact retrieved dtc: p219a for fuel injector failure. The vehicle was not repaired. The contact stated that the failure was known to the manufacturer, who had issued TSB number: 21-010; however, the vehicle was no longer covered under warranty. The manufacturer was informed of the failure and referred the contact to the NHTSA hotline for assistance. The failure mileage was approximately 85,000.

Traveling from appointment to home, vehicle started to rattle from engine, could not accelerate and shut off in the middle of the roadway. We couldn’t start the engine and “emission system failure “ message appeared for the first time. Prior to the event, we did not have any issues with starting, operating the vehicle and no warning lights on the dash. Police arrived to block traffic and ordered the tow to the dealership. Honda did a diagnostic for 240. 00. Results were they found metal shavings in the oil and the engine needed to be replaced. We were surprised due to the fact that we just had a full synthetic oil change within the past month and no reports of metal in the oil were reported. Honda stated that recall 23v-751 addressed this issue but our VIN was not listed for coverage. Only choice is to replace the engine assembly, quoted $9,000. 00. We are just thankful this issue didn’t result in any accidents or injuries when it reduced power and unexpectedly stalled on a city road. We are 1st owners and have had all services done professionally, per the maintenance schedule. It’s a 2019 Honda Odyssey touring with 70000 miles. No prior notice or poor performance. Honda confirmed it was an internal bearing failure. Vehicle is available for inspection, currently waiting on engine replacement to arrive. Honda did complete the recall for fuel pump replacement that was needed.

Engine failure. Not available for inspection. Engine replaced and damaged engine return for core charge. While driving on the highway, without any for warning, engine stalled, loss of power and dash read “emissions system problem “. Vehicle was towed to Honda of denton for diagnostic testing. The engine stalling and loss of power at highway speeds caused a great risk for my family in the van. We impeded traffic and could have caused an accident. There were no warning lights and/or engine system issues leading up to the engine failure. Honda stated that it’s is a common issue with the internal engine bearing failure. They also confirmed that my VIN is not listed on the recall list for the 2 million engines effected. Honda quoted a lkq engine replacement. Declined and had replacement done at caliber collison.

Connecting rod bearings rattling at 72000 miles on my 209 Honda Odyssey. Loss of power.

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.

I was traveling approximately 65 mph on interstate 75 southbound near cincinnati, ohio with the flow of traffic. Cruise control was not being used at this time. I felt a sudden loss of acceleration and heard a shrieking sound. I also observed the check engine light illuminate. I immediately signaled and moved toward the right shoulder from the middle left lane. Upon entering the far right lane, the same loss of power and shriek sound happened. I took the exit ramp to sharon road and upon releasing the accelerator, the vehicle's engine stalled. I coasted to a stop in the far left turn lane. I personally inspected the vehicle and upon using a scope into the spark plug holes, found that the center rear cylinder shows signs that the piston collided with at least one valve, and the piston does not move with the crankshaft. However, the rear valves do move. The front center piston and valves both move. This suggests a connecting rod issue.

The contact owns a 2019 Honda Odyssey. The contact stated that while her son was driving at 70 mph, he crashed into a deer. The air bags did not deploy. After investigation, the contact linked the failure to NHTSA campaign number: 24v064000 (air bags). A police report was filed. There was no reported fire. The driver struck his head on the steering wheel and sustained head injuries, and medical attention was provided on the military base. While driving, the vehicle stalled at the entrance of the military base. The vehicle was towed to an auto body repair facility. The vehicle was being recalibrated. The air bag light was illuminated. The mechanic determined there was an issue with the seat belt pretensioner. The mechanic determined that the air bag sensor was not hit during the crash. The contact called the local dealer, who confirmed there were no recalls. The vehicle was not diagnosed or repaired. The manufacturer was not notified. The failure mileage was approximately 77,000. The VIN was not available.

My engine lights started flashing. I was stranded with my children. Had to coast into a nearby gas station. I’m told it’s a failed monocular camera causing all of it. When I google that it looks like it has happened to so many people! a recall needs to happen.

While traveling in my 2019 Honda Odyssey (40,000 mile) the vehicle completely shut off and placed itself into neutral. The warning lights for emissions system problem, brake problem, and parking assist problem lit up on the dashboard. The vehicle went into neutral and would not allow me to drive at all. Then the vehicle shut off all within 30 seconds. The vehicle would then not restart and now I have to get the vehicle towed to the Honda service department. After looking through other complaints there is a known recall for manufacturer defected fuel injectors for my year model Odyssey but does not appear when I search for recalls. This was an insanely dangerous situation here in oahu where the traffic is very bad. The vehicle gave no warning or check engine light and we have completed every service for the vehicle. The vehicle just randomly completely shut off and would not restart leaving my family of 5 stranded.

While accelerating from a complete stop at a red light, immediately after refueling, the vehicle suddenly lost all propulsion power and forced itself into neutral without any driver input. The dashboard lit up with numerous system warnings at once, including: •emissions system problem •brake system problem •abs problem •brake hold system problem •electric parking brake problem •vehicle stability assist (vsa) problem the engine won't start, leaving me stranded in the middle of an active intersection. I attempted to restart the vehicle multiple times with no success. Police responded to the scene, confirmed the vehicle could not be driven, and a tow truck transported it to a nearby Honda dealership. The tow truck driver suspected an alternator failure, but the dealer’s inspection the next day could not reproduce the issue. They reported that the alternator and battery “tested fine” and that no trouble codes were stored in the ecu. No repairs were performed, and no cause was identified. Safety concern: this incident created an immediate traffic hazard. The vehicle’s sudden loss of propulsion in traffic, combined with the inability to restart, could easily have caused a collision. Multiple critical systems were reported as failed simultaneously, indicating a possible electrical, fuel system, or control module failure. I am aware of similar complaints from other 2018–2019 Honda Odyssey owners in which sudden power loss occurred, often accompanied by numerous system fault messages. Many reports link these events to fuel pump failures, loose battery/ground connections, or transmission control malfunctions. This suggests a broader pattern of intermittent safety-related defects. Requested action: please investigate this incident and similar cases for potential design or component defects.

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.

Was driving on my way to work and I heard a sharp sound while going up a hill. I then got warnings that said transmission issue, pull over immediately when safe and the car shifted itself into neutral. I was in the middle of traffic and lost all acceleration controls, while being forced out of the drive gear. I lost all speed and had to move through traffic and get to a side street. The same thing happened to me about a year and a half ago. It was covered by a warranty but I still was experiencing losses of car power or stalling.

Car shut down for idle stop when I let foot off break the car did not start back up. Car died and I needed to restart car.

Intermittent hesitation to accelerate.

Upon coming to a complete stop on the freeway, the idle engine feature stopped the engine. Upon letting go of the gas, the engine wouldn't restart and the electrical systems in the car malfunctioned showing a restart of the car would be needed. After trying to restart the car, the engine wouldn't turn over. After pushing the off button and starting the car again, it finally restarted. This created a hazardous situation as there was the potential for the car behind us to rear end us since we were at a complete stop on the freeway. After the software update, this happened again at a right turn on a local street.

Auto stop start feature caused car to stall at a traffic light. Could didn’t not restart when brake pedal was released. Car did not restart until door was opened and key was cycled several times.

The contact owns a 2019 Honda Odyssey. The contact stated that while starting the vehicle, the contact heard a ticking sound coming from the engine compartment. There was no warning light illuminated. The vehicle was taken to the dealer where it was diagnosed that the rod bearings had failed, and the engine needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 103,000.

Nothing has happened yet, but I have been unable to get the connecting rod bearings inspected per the Honda safety recall notice. I contacted the Honda dealer in January of 2025 to have the bearings inspected, as well as to have the fuel pump replaced (also under recall). I wanted them both done at the same time. I set up an appointment for may 21st of 2025, because that date was the first mutually available date for the dealer and me. Later in the day, on may 21st, I got a call from the service department that my fuel pump was done, but they did not do the bearing inspection. I went to pick up the vehicle at the dealership only to find that the check engine light was on, so I had to leave the vehicle overnight so that the check engine light problem could be corrected. It was then that I was told that they could not do the connecting rod bearing inspection because the procedure requires a "special tool" and Honda had to send it to them. I find this strange because of the number of months that went by, from when I first contacted the dealership until the appointment date, and I thought that they would have been better prepared to complete the work. I was also informed by Honda that all of the parts necessary to do the bearing inspection were available. I received that notification on September 4th of 2024. I also find it strange that, out of nearly 250,000 affected vehicles, I am the first to request this service at this dealership. I was not told how long it would be until the dealership service department would receive the tool. In the recall notice from Honda, a connecting rod failure could potentially result in ". . . A fire, crash, or injury". That's the risk. I was told by Honda to continue driving the vehicle if I was not having any symptoms of failure. I have had no indications, but I would like to have this recall taken care of as soon as possible.

I am filing this complaint to report a recurring and costly defect involving the starter system in my Honda Odyssey. The vehicle has been experiencing starter failures every few months, requiring repeated repairs and part replacements. Each time the starter fails, I am left stranded without warning, creating a serious safety hazard, especially when the failure occurs in public areas, on road shoulders, or during emergencies. The defect has caused extreme inconvenience, financial strain, and raised serious concerns about the reliability and safety of this vehicle. Given the frequency and cost of the problem, I believe this constitutes a systemic defect that should be investigated for a potential recall or manufacturer responsibility. I urge the NHTSA to thoroughly investigate this matter to determine whether this ongoing issue with the starter poses a broader public safety concern and qualifies for regulatory or enforcement action.

This vehicle is horrible and should be bought back by Honda. They knowingly put this bad engine in the 2018-2019 year models for the Odyssey. The transmission grinds. The read door opens. The engine shuts off while driving at high rates of speed. You then have to pull to the side of the road and turn the ignition off, open the door, and restart the vehicle. I have complained to Honda for a buy back and they flat out said no! please help.

The contact owns a 2019 Honda Odyssey. The contact stated that upon starting the vehicle, the messages "emissions system failure", "brake system failure", "brake hose system failure", "power steering failure", "eps failure, "vehicle stability assist (vsa) failure", "hill start assist failure" and "road departure mitigation system failure" were displayed. The vehicle was taken to the dealer, where it was diagnosed that the fuel injectors had failed and needed to be replaced. The vehicle was not repaired. The manufacturer was informed of the failure and a case was filed. The manufacturer referred the contact to the NHTSA hotline to file a vehicle safety complaint. The failure mileage was approximately 120,000.

My 2019 Honda Odyssey has only 63,545 miles on it. The vehicle recently began making strange "rattling" sounds from inside the engine block when driving. I took the car into the dealership (Honda of oakland) and learned from the technician that the rod bearings and/or connector rods are damaged. The engine needs to be completely torn down. To repair the car, I will need to purchase a new engine. The cost estimate is $13,000. Looking online, I discovered there is an ongoing recall for this issue affecting many 2018-2019 Honda Odysseys. Somehow, my vehicle has been excluded from this recall despite exhibiting the exact same problem(s) that the other recalled vehicles are experiencing. It appears that the existing recall parameters for the cars being affected by this bearing rod issue are too narrow. Many more Honda Odysseys are experiencing this same problem. I called american Honda for further assistance and they declined saying that the vehicle is outside of the warranty period and they are not obligated to help. I purchased this vehicle from the Honda of oakland dealership - during my ownership, the car has passed many multi-point inspections. Nothing I have done (or did not do) has contributed to the problem - it is purely a manufacturing defect. The technician tells me that, if I don't make this repair, the engine could "seize-up" on the road while driving. This condition poses an active safety hazard for Odyssey owners.

The contact owns a 2019 Honda Odyssey. The contact stated that while driving at an undisclosed speed, the contact noticed an unknown message displayed. The vehicle was taken to the dealer where it was diagnosed that the timing belt tensioner had failed and needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure and referred the contact to the NHTSA hotline for assistance. The failure mileage was approximately 90,400.

I have had a recurring problem for years that the dealership has been unable to resolve. Occasionally while we are at a stop, and the engine auto off system kicks in, and then I tried to go again, the car stalls completely. Battery tests fine. It does not restart until sometimes after I open and close my driver side door a couple of times which I assume reboots the electrical system in some manner. The car then starts up again and is okay. This is extremely dangerous as it happens in the middle of driving down the road, and the dealership has been unable to identify a solution or what the real problem is.

The automatic engine start stop when at a stop while driving creates dangerous conditions. The engine stalls during the re-start and it seems to pull the voltage all the way down to where every controller is dead and restarting. Cycling ignition switch while cluster is black or restarting or throwing up bunches of fault messages as traffic is now moving and you are still stopped. Sometimes this re-boot process can take around 30 seconds (guessing, I'm freaking out during those moments so time is tough but it feels like a long time). I have not had an accident yet but definitely some very scary moments with wife and kids in the vehicle. This auto stop feature can be disabled but requires you hit the button with each ignition cycle and I don't always remember to do that. The Honda Odyssey currently has 80,000 miles on it, we bought it new in 2019 and this has been happening since it was new. We have had this reviewed at two different dealerships; there seems to be a dismissive attitude by the service departments. They have replaced batteries and there was a software update in early 2024 but this issue is definitely still present.

2019 Honda Odyssey - since about 100,000 miles, a knocking sound has begun to present itself, and has gotten progressively worse. The vehicle is now at 129,000 miles and the sound has been diagnosed by 2 different repair shops as "rod knock" due to premature bearing wear. This is exactly what 250,000 vehicles were recalled for back in January 2024, however, this vehicle's VIN was not included in said recall. The repair shops have quoted the vehicle owner $9000 for full engine replacement with a used Honda engine that could potentially have the same manufacturer defect that the engine being replaced has.

Vehicule does not respond when push the gas pedal. There is a delay on the vehicule respond after push the gas. Creating false idea of not pushing the gas enough. Suddenly the vehicule react loosing control.

Since purchasing the vehicle, I've had several incidents where my safety and those inside my vehicle are compromised due to the loss of drive power and stalling of the vehicle while driving. I've complained to the dealer for which they continued to assure me that there was no problem detected during the safety inspections. Recently I received the recall notice to replace the fuel pump module which was causing the issues that I've experienced with my vehicle. I took my vehicle to the dealer on 11/11/24, where it was serviced to correct the recall issues. However, I continue to have the same problems of stalling and loss of drive power when driving the vehicle. There are no warning lamps or other issues detected by the dealer according to their safety inspection. My safety and the safety of my passengers, continues to be put at risk. While driving in the highway it is especially dangerous because when I'm changing lanes the vehicle will not accelerate putting me at a risk for a collision. When I am turning left into a street, I feel that it looses power and am stalled in the middle on the street risking yet again a collision. These incidents occur at least 90 percent of the time when driving.
