2018 Honda Odyssey fuel system problems

Filed Oct 8, 2026 · Engine, Fuel system · VA

The vehicle was stalled on highway local about seven times. My car got stranded and almost got into serious accidents. This happened multiple times and Honda couldn’t fix it. I spent $9000 and couldn’t find the problem. Honda changed fuel injectors, pump, regulator, high pressure. But the car is still stranded on highway which is very dangerous

The Fuel Injectors are failing which is causing a safety concern with regards to moving the vehicle. There was a warranty extension on these items that does not go far enough to remedy the issue. The components have been inspected and confirmed by the Burns Honda Dealership in Marlton, NJ. Because the vehicle does not consistently accelerate, it is a safety risk.

1. Component failed: The low-pressure fuel pump failed. The vehicle is currently sitting at my residence and is available for inspection upon request.2. Safety risk: The vehicle stalled completely while driving, causing an immediate loss of propulsion on a public road, creating a severe collision risk.3. Confirmation: The problem has been pulled and confirmed by an independent service center (AutoZone diagnostic scan tool), which pulled a code to replace the fuel pump.4. Inspection: The component has not yet been inspected by the manufacturer, police, or insurance representatives, as the manufacturer is currently refusing to authorize an inspection due to a salvage title.5. Warning lamps/Symptoms: Immediately prior to the stall, a complete cascade of warning lights appeared on the dashboard simultaneously, and the vehicle sputtered aggressively upon attempting to crank and restart.Assessment: This is the identical, textbook physical failure condition of the federal safety agency Campaign 23V‑858 regarding defective factory-installed Denso fuel pumps in 2018 Honda Odysseys. American Honda Corporate is using an automated salvage title database filter as a pretext to deny mandatory federal safety recall remedies on a vehicle with zero structural fuel system damage.

This vehicle is actively immobilized on private residential property with its central ADAS safety networks and Advanced Driver-Assist networks completely crashed and offline (DTC U3000-49) and active short-to-ground circuit failures (DTC B2035) rendering the passenger sliding doors completely inoperable, creating an immediate entrapment and safety hazard. These progressive component failures cascade directly from severe environmental moisture intrusion inside the rear tailgate enclosure. This exact water migration vector intersects directly with active federal safety campaign the federal safety agency Recall 26-V-423 (Rearview Camera Failure), which isolates moisture intrusion into the panel housing as the root factory manufacturing defect. A manufacturer franchise location documented active water leakage onto the Power Tailgate Control Unit and heavy corrosion on the wiring connector under a previous Repair Order but performed zero interim moisture sealing, corrosion cleanup, or terminal mitigation, allowing progressive water migration to completely destroy the wiring system harness. Furthermore, American Honda Corporate Case Management explicitly stated on a recorded verbal line that the manufacturer is denying all repair assistance to remedy these cascading safety campaign electrical defects under an active corporate case. The manufacturer is in open default of its statutory federal obligation to remedy a safety recall defect free of charge to the consumer.

I am reporting American Honda’s ongoing failure to safely remedy critical safety defects and recalls on my 2018 Honda Odyssey (purchased new), resulting in severe vehicle degradation and a life-threatening traffic hazard. The vehicle has been to an authorized dealer over 21 times.SAFETY RECALL NEGLIGENCE & POWERTAIN DAMAGE: At 95k miles, the vehicle displayed active check engine codes P0087 (Low Fuel Pressure), P0420, and P0430. The dealer replaced injectors, but severe fuel issues persisted. The dealer utilized stall tactics, claiming they "could not duplicate" ongoing stalling/hesitation symptoms. When the official fuel pump recall was issued, the bulletin mandated priority service for vehicles actively displaying symptoms. My vehicle met these parameters. However, when I attempted to get the recall performed at 111k and 120k miles, the dealer denied service due to part shortages, instructing me to drive the vehicle until it "completely broke down." Because Honda failed to supply recall parts to a symptomatic vehicle, I was forced to drive it a defective car for an additional 46,000 miles. A replacement pump was installed at 166k miles, but the prolonged forced operation directly caused the high pressure pump to fail and raw fuel to melt both catalytic converters. The dealer issued a $6,000 repair estimate for damage engineered entirely by Honda's recall delays.LIFE-THREATENING TCM FAILURE: One day after a related service visit, the Transmission Control Module suffered a catastrophic electrical failure. The engine completely shut off without warning while I was actively facing four lanes of oncoming traffic, creating an immediate, severe collision risk.BROKEN SLIDING DOORS: The power sliding doors failed under 12 months of ownership. Despite 7+ repair attempts, they remain broken, posing a severe structural/occupant safety hazard. Requests for trade-in intervention since 60k miles were systematically ignored.

Back in the fall/winner of 2024 (could have been 2025) my Honda Odyssey had a recall for a low pressure fuel pump. However, Honda and many other dealers were dealing with hundreds of thousands of recalls, and we’re only recalling the vehicles with actual symptoms. My vehicle was hesitating and experiencing sudden loss of power during acceleration therefore Honda agreed to repair my vehicle. Everything seemed to work fine after that with no issues, but approximately three months later, I was having issues with my vehicle and brought it into my Mechanic, to find out that my high-pressure fuel pump was not working properly. Upon further investigation, I found out that a bad low-pressure fuel pump starves the high-pressure fuel pump (HPFP) of required volume. This causes the HPFP to work far beyond its design limits to build pressure, leading to cavitation (vapor bubbles damaging internal components), overheating, and premature mechanical wear from metal-on-metal friction. When I dug a little deeper, I found out that many Honda owners were dealing with failing high-pressure fuel pumps after having their low pressure fuel pump recall repairs completed. Many in which were in a similar timeframe to mine. Honda offered me no good merit assistance and stated that unfortunately, I would be liable for the entire cost of the repair. It is more than obvious that the failing of my low pressure fuel pump impacted the performance and workload of my high-pressure fuel pump, causing it to fail, which I believe Honda should be liable for replacing. Please look further into this matter to help others like me that had their low pressure fuel pump recall performed, and shortly after needed to replace their high-pressure fuel pump at their own costly expense.
