2019 Honda Odyssey: sudden loss of power

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.

By August 1, 2026, the check-engine light was on in my 2019 Honda Odyssey. I reported that the light was steady and the van was running normally, with no noticeable drivability problems. On August 31, 2026, at 141,126 miles, an authorized Honda dealer recorded DTC P0430, performed an air/fuel test, documented that the fuel injectors failed, and recommended replacing them. The dealer noted that failed injectors can cause P0430. The injector-specific parts-and-labor estimate is $1,849.06. No injector repair or post-repair test is documented yet. There was no crash, fire, injury, fatality, or police report. Honda Service Bulletin 21-010 provides a 10-year/150,000-mile injector warranty extension for certain 2018-2019 Odysseys. For P0430, it directs an air/fuel test and injector replacement if the test fails. Honda says this vehicle's VIN is ineligible despite the dealer's matching diagnostic pathway and offered 50% goodwill. This bulletin is a warranty extension, not a recall. I ask the federal safety agency to examine whether the eligible VIN population adequately captures 2019 Odysseys with this documented failure pattern. The attached evidence summary identifies 27 public the federal safety agency complaints that report injector or matching-code concerns together with VIN-based coverage exclusion; those are owner allegations, not confirmed failure rates. Some other owners allege hesitation, power loss, or limp mode, but I have not experienced those symptoms. I am concerned that continued injector deterioration could create a future drivability or loss-of-power risk. Please compare Honda's production, warranty, goodwill, dealer-test, and failure-analysis data for included and excluded vehicles. The dealer findings and evidence summary are attached.

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

Failed Component: Direct Fuel Injector Set. The components are currently on the vehicle and are available for inspection upon request. Safety Risk: The failing fuel injectors create a severe engine air/fuel imbalance, which causes engine hesitation, engine stumbling during acceleration, and unpredictable power loss. This puts my family at high risk of a collision, particularly when merging onto highways, crossing busy intersections, or accelerating from a stop. Furthermore, dumping unburnt fuel into the exhaust risks overheating the catalytic converter, creating a potential fire hazard. Dealer Confirmation: Yes. The problem was confirmed by AutoNation Honda 365 in Memphis, TN, on [XXX] (Mileage: 83,452). Manufacturer Inspection: The vehicle was inspected by factory-trained technicians at an authorized Honda dealership. A case was opened with Honda Corporate, but they refused to cover the repair, stating my specific VIN batch was excluded from their warranty extension, despite suffering the exact same failure. Warning Lamps & Symptoms: An "Emissions System Problem" warning and the Check Engine Light illuminated on [XXX]. Incident Description & Cause: Honda is fully aware of this dangerous defect. They issued Service Bulletin 21-010, acknowledging that "debris from the high-pressure pump or the fuel injector machining process can cause internal wear or clogging" in 2018-2019 Odysseys. Following the TSB 21-010 protocol, the dealer pulled code P219A and performed a "Cylinder AF Test." My vehicle failed the test (Cylinder 3 running rich). The Honda technician’s official notes state: "Fail air fuel test need injector set internal failure." Honda extended the warranty to 10 years/150,000 miles for this known manufacturing defect, yet they are arbitrarily excluding my 2019 Odyssey, which has the exact identical internal failure documented by their own dealer. Honda's refusal to issue a full recall leaves all affected drivers at risk. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C.

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 the federal safety agency 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.

I am writing to open a formal complaint regarding a serious transmission defect in my 2019 Honda Odyssey (VIN: [XXX] ). My vehicle is currently exhibiting symptoms that directly match the 'Transmission Programming Defect' documented in ongoing litigation, specifically symptoms: while accelerating produce rough and delayed shifting; sudden jerking, sudden, harsh accelerations and decelerations; and a sudden loss of power. I am aware of Case No.XXX (XXX v. American Honda Motor Co.) and Case No. XXX (XXX v. American Honda Motor Co.), which allege that the 9-speed ZF 9HP transmission in my model year suffers from a design defect. These transmission failures create a significant safety hazard. Recently my van report code as transmission system problem the second time. We got mechanic checked and confirmed it is transmission issue. The first time when it happened, we drove the van on highway and suddenly it lose power and slow down by itself. there was no response even we applied gas. We went down highway and drove to a close-by repair shop. they replaced some part for us but it didn't resolve the issue. This time since the error comes, it won't speed up in lower speed except the speed goes beyond 40-50 miles plus. when we back the car, it responses slow or none. it comes with big noise also now. it definitely gets worst. The very common issue when you stop and start to move, it never responses from the beginning even we applied gas, even the passenger can feel the reluctance. it also happens when the van turns. we also had the experience when driving on the highway, it speeded automatically without driver applied the gas. It feels like someone pushing us behind. there was Transmission Control Unit recall for 2018-2019 Honda Odyssey (Touring/Elite). Honda actually knows the issue but they didn't reveal this to their customer. This brings life threatening concerns on the highway. I hope this complaint can save lives and family INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(

My 2019 Honda Odessey has had transmission issues since the very beginning. I've experienced jerking/shaking, hesitation before accelerating, delayed shifting, sudden loss of power. Fortunately none of this has resulted in any accident or injury. Unfortunately, yesterday (4/4/2026) I got charged $271.34 to have to transmission warning light read only to be told, "we cleared all dtc then test drove the vehicle. No dtc found after we drove the car...if the consumer complain again he will have to replace the transmission." Of course the warning light appeared again today. The dealership seems to be completely unaware of the multitude of transmission issues documented even though this appears to be a known and well documented defect based on the class action lawsuit Browning, et al. v. American Honda Motor Co., Inc., et al. They charge me for the analysis and send me on my way as if they have no idea what is going on with my vehicle. I am the sole owner and have kept the vehicle well maintained at Leith Honda, 3940 Capital Hills Drive, Raleigh, NC 27616 and I have had all manufacturers recalls handled in a timely manner. I'm sure they can provide service records if needed. The bottom line is they are not being fully transparent and I am paying for their lack of transparency and more importantly putting me and my family at risk by not disclosing the potential risk due to the faulty transmission in these vehicles.

I am reporting a safety issue involving my 2019 Honda Odyssey transmission. Since early ownership, the vehicle has had ongoing hesitation and delayed response when accelerating, especially during gear shifts. Over time, this condition has worsened and now includes intermittent loss of power when pressing the accelerator, followed by sudden jerking or lurching forward. The most serious incident occurred recently when the vehicle unexpectedly shifted into park while moving in a parking lot, creating a dangerous and unsafe condition. Additionally, there have been multiple instances where the vehicle hesitated in intersections, creating a risk of collision due to lack of response when attempting to accelerate. Honda dealership technicians have acknowledged that these vehicles are known to have rough or problematic shifting, indicating this may be a broader issue. The final issue has resulted in the vehicle being towed to the dealership for a full evaluation.

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.

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).
