general problems of the 2019 Honda Odyssey - part 1

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.

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).

[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.

The contact stated while the contact's husband was driving at an undisclosed speed, the accelerator pedal was depressed, however the vehicle failed to accelerate as intended. The contact noticed an abnormal knocking sound. The vehicle was driven to the shoulder of the road. The contact stated that several unknown warning lights illuminated, and the vehicle lost motive power. The contact's husband attempted to start the vehicle, the vehicle did restart. The failure reoccurred. The contact stated that the abnormal knocking sound became louder and persistent. The vehicle was towed to the dealer where it was diagnosed with a failed engine. In addition, the contact was informed that metal shavings were noticed in the oil pan. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. The contact referenced a recall, NHTSA campaign number: 23v751000 (engine and engine cooling) however the contact's VIN was not associated. The manufacturer was made aware of the failure and a case was filed. The failure mileage was approximately 130,000.

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.

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.

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.

Vehicle intermittently loses propulsion during acceleration when merging. Engine rpm remains low despite throttle input. After a delay, transmission re-engages abruptly with a metallic scraping noise. This creates unsafe merging conditions. This happened today, 2/14/2026 in 4 instances in the same trip. It has also occurred approximately 50 other times over the past six months when the mileage was as low as 66,100 miles.

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.

"emissions system problem" engine warning light has been on for quite some time. I know there is a service bulletin related to this issue, but my VIN is not covered. There are also several other warning lights that occasionally pop up, and my Honda dealer believes these are all related to the initial warning light. They mentioned that sometimes these systems start shutting down so the vehicle runs properly. Recently I received "transmission system prolem" (in conjunction with the slew of warning lights I have frequently been getting). No apparent issues until recently when I was driving on the interstate. The engine started to become very loud and when I looked at the rpms it was very high, over 5,000 rpms. The car wasn't shifting out of first gear at 55mph. I immediately slowed down and got off the interstate as soon as possible. After arriving home, we unhooked the battery, re-installed, and all of the warning lights were gone. Again, the Honda dealer believes all of these issues were realted to the "emissions system problem", which is part of a service bulletin that should be covered by warranty extension. I beleive my VIN should be included, and the recent transmission system problem which happened on the interstate was very dangerous and could have ended very badly, had I not been in tune with what was happening.

As I was driving the car computer showed overheating, brake failure, transmission failure and the car started shaking and the engine died. I had the car towed by triple aaa to a auto repair shop, but the next day when they went to fix the problem could not replicate it.

The contact owns a 2019 Honda Odyssey. The contact stated that while driving at approximately 65 mph, the vehicle unexpectedly entered limp mode, and the check engine warning light started flashing. The vehicle was able to restart following the failure. The vehicle was towed to an independent mechanic, where it was diagnosed that the connecting rods had failed. The contact was informed that the connecting rods needed to be replaced, or the engine needed to be replaced. The vehicle was not repaired. The dealer was contacted. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 105,000.

The 2019 Honda Odyssey experienced an engine failure while driving on the highway in the chicago area in illinois. The engine began knocking, then failed completely. It was towed to a local Honda dealer, where the technician noted visible metallic flecks in the oil once drained. No check engine or other warnings occurred prior to the failure.

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.
