2019 Honda Odyssey: check engine light

Filed Sep 15, 2026 · Fuel system · OH

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.

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!

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 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 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)

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.

"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.
