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 NHTSA 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 NHTSA 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.

COMPONENT THAT FAILED & AVAILABILITY: The vehicle's primary electrical architecture and data communications network (CAN bus) failed during a safety recall service for the SRS ECU and rearview camera. After attempting to complete the recall work, the vehicle is no longer able to start. SAFETY RISK: The manufacturer's federally mandated safety recall remedy compromised the vehicle's critical safety and control infrastructure. This rendered a previously reliable family vehicle entirely inoperable, destroying its ability to communicate, start, or turn on. It poses a systemic safety risk if the corporate recall procedure itself causes severe electronic failures in consumer vehicles. REPRODUCTION & DEALER CONFIRMATION: Yes. The failure was induced directly by Williams Honda ([XXX]) during service on Thursday, XXX. The dealership's Service Manager explicitly confirmed to me that their technicians compromised the electrical architecture while performing the SRS ECU and rearview camera recall work. The vehicle has remained dead at their facility ever since. INSPECTION BY OTHERS: The vehicle has been actively inspected by dealership technicians in coordination with Honda Engineering headquarters. It has not been inspected by police or insurance representatives, as no crash occurred. I have requested an inspection by a Honda Corporate Field Technical Specialist (FTS). WARNING LAMPS & PRIOR SYMPTOMS:NONE. Prior to this appointment, the vehicle was in perfect electrical and mechanical working order. There were absolutely no warning lamps, messages, or symptoms of any starting or electrical problems. The vehicle had just safely completed a seven-hour road trip immediately prior to being dropped off for the recall work.

A warning for Power Tailgate Problem keeps coming up. It tried to open multiple times while driving, beeping at us. It wouldn’t open with the buttons at all. We had to manually open and close it. This makes the second time it’s done it. And it always has to do when it rains. Honda knows this is a well known issue with their odyssey’s and it needs recalled. The dealership wants us to pay for a well known issue. We had a friend with the same year odyssey and the same thing happened but their tailgate completely opened a few times while driving.

Early in a driving session, the accelerator pedal, when applied pressure, will not rev the engine and provide power to the wheels for 1-3 seconds. This issue happens once or twice in a driving session and then doesn't do it again until a future driving session. It is random and doesn't happen every session. This issue causes me to have concerns entering traffic, particularly left turns, as I am unsure if the vehicle will accelerate when needed to safely enter traffic. I have had Service Bulletin 19-124 completed on my vehicle and it did not fix the issue.

2018 Honda Odyssey Elite I am reporting an unresolved issue stemming from a failed recall remedy for NHTSA Safety Recall 23V-431 (Honda TSB 20-049) regarding the MOST bus fiber-optic network. My vehicle has been taken to an authorized Honda dealership twice to receive the official recall repair (replacing the FAKRA network connectors). Despite these two repair attempts, the network defect continues to escalate.The vehicle experiences sudden, violent, and near-constant loud popping and clicking noises through the audio speakers while driving. This occurs both at random and predictably when driving over bumps. Following the increase in these network pops, the vehicle's Blu-ray player completely failed and stopped working. Furthermore, the central infotainment screen frequently freezes, reboots, and displays an "Audio Connection Lost" error message, which also cuts out the FM radio tuner entirely.Crucially, this fiber-optic network failure recently caused a total loss of the digital instrument cluster and speedometer while driving. While this complete cluster blackout has only occurred one time so far, it presents an unpredictable and dangerous safety hazard, as I am left with no knowledge of my current speed or critical vehicle safety alerts while in motion.The manufacturer’s standard recall remedy of swapping plastic connector clips is ineffective for my vehicle. The recurring failures after two repairs indicate a permanently compromised factory wiring harness or a damaged network module that is continuously dropping the signal. The manufacturer needs to authorize a thorough diagnostic and full harness/module replacement to permanently resolve this safety defect before the instrument cluster fails again.

Failure of the forward-looking multipurpose camera after a simple battery change. Many safety features are now inoperative including emergency braking, lane keeping assist, adaptive cruise control, among others. Ultimately, a routine maintenance item (battery replacement) is causing the failure of vehicle safety systems.

On 7/28/26, my 2018 Honda Odyssey began displaying the following warning lights and system messages on the dash: •Adaptive Cruise Control (ACC) system error •Lane Keeping Assist System (LKAS) error •Auto High Beam system error •Collision Mitigation Braking System / forward collision error These errors were present before I replaced the 12V battery. I had the battery tested at that time and it failed a load test, so I replaced it, expecting the ADAS-related errors to resolve. After the battery replacement, the original errors remained, and additional warning lights appeared, including a transmission system problem indicator and a brake system warning light. I disconnected the negative battery terminal for approximately 10 minutes in an attempt to reset the modules, then reconnected it. After reconnection and a period of idling, further warning lights appeared that had not been present immediately after the battery swap. I have not been in a collision, and there was no impact to the windshield, front bumper, or brake components at any point during this period. The vehicle’s brake pedal feel has remained normal. Because these errors were present before the battery was replaced, the battery does not appear to be the root cause, and the underlying issue affecting the ACC, LKAS, auto high beam, and collision mitigation systems remains unresolved. I have seen reports from other Honda owners describing similar cascading ADAS and system warning lights on comparable Honda models.

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.

The contact owns a 2018 Honda Odyssey. The contact stated that while a customer on Turo was driving the vehicle, the instrument panel warning lights flashed and the climate control system failed to function. The vehicle was restarted multiple times, but the instrument panel warning lights remained illuminated. The contact stated that while being driven, the vehicle was pulled over by law enforcement because the taillights failed completely. The vehicle was taken to the dealer, where it was diagnosed that the gauge control module had failed due to corrosion from water damage. Upon further inspection during the replacement, the dealer discovered additional failures within the body control module and the taillight wiring harness. Technicians determined that the electrical failures were caused by water leaking from the rear windshield into the tailgate area. The vehicle was repaired; however, the water leak source was not addressed or sealed. The manufacturer was notified of the failure. The failure mileage was 144,411.

The vehicle experienced a sudden loss of power and entered limp mode, with multiple safety and driver-assistance systems shutting down at once (adaptive cruise, braking assist, lane/road departure mitigation, EPS, etc.). A Honda dealer (Allen Honda, College Station, TX) retrieved DTC P0369 and documented that the front camshaft is worn and has thrust forward, contacting the camshaft position (CMP/TDC) sensor and damaging the thrust plate. The dealer is recommending an internal engine repair costing several thousand dollars. I am very concerned because Honda has already acknowledged serious engine defects in this same J35 V6 family under Recall 23V751 (connecting rod bearing wear leading to engine damage and stall) for 2018–2019 Odyssey, yet my dealer states my VIN is “not part of the recall” and that this is a “separate issue.” In practice, I am seeing a major internal engine failure that causes sudden derate and disables multiple safety systems, but I am being told there is no recall coverage or assistance simply because my individual VIN falls outside Honda’s current recall production range. I am requesting that NHTSA review this incident as a potential recall exclusion problem: owners with the same engine family and serious internal failures are being denied recall coverage on a technical VIN cutoff, even though the safety consequence—loss of power and shutdown of critical safety systems while driving—is similar to the failures already recognized under Recall 23V751 and the ongoing engine defect investigation. I believe this situation may warrant expansion of existing recall coverage or a new recall campaign for currently excluded VINs like mine, and reimbursement for owners who have already paid for these repairs.

All warning lights began flashing after a SRS recall fix at Honda of Joliet, Illinois. Dealer wanted to do a in depth vehicle scan for $279. I brought it to an independent care repair shop where they did the scan for $199. They found engine damage per attached report. My vehicle’s VIN was not included in the initial recall for the same problem for the same vehicle, year, and engine type. Contacted Honda Customer service a more or less ‘good luck’ response.

For a couple of weeks we have been having issues with our 2018 Honda Odyssey's back right door. When you go to open it, something happens where it makes it shut after fully opening. Our resolution for the time was to just push on the door harder and it would continue to slide open. Today, on XXX I was going to put my [XXX] son in his carseat, which is located mid van right side. He snuck infront of me and was standing in the path of the sliding door, it did what it normally does, the same door did not detect his body and began shutting on him. As it was squeezing his shoulders I was pushing back on the sliding door with all my strength, and after a few seconds it opened back up. I'm not sure whether the sensor failed, or it can't detect past a certain height, but either way it was a very scary situation. This had just happened an hour ago, so I haven't reported it to any authorities or anything. I came home and googled how to make a manufacturer report and it lead me here. If I had not been standing behind my son, I believe the door would have continued shutting more, enough to sustain serious injuries if not more. My son physically was okay, aside from a red mark on his upper arm where the door was shutting on him, he did need at least 5 minutes of consoling after, which only happens when something truly hurt him.

Recall 23V-431 (Honda 23-046) was previously performed on my vehicle to address MOST communication network failures affecting the infotainment system and backup camera. Despite the recall being marked complete, I continued experiencing intermittent infotainment failures. Symptoms include “Network Connection Lost” messages, complete loss of the center display, audio failure, Apple CarPlay disconnects, system resets, and loss of the backup camera while reversing. The failures frequently occur while driving over bumps, during turns, and recently while backing into a parking space. Because the issue persisted, I sought a second opinion from another Honda dealer. During their inspection, they advised that required portions of Recall 23-046 had not been completed by the original dealership that performed the recall. The service advisor informed me that system history had not been cleared, a factory cable reset had not been performed, and the audio unit had not been properly initialized. In a follow-up text message, the advisor described the situation as a “workmanship error” by the original dealership. The remaining recall procedures were completed, however the same symptoms returned immediately afterward. The center display, audio, Apple CarPlay, and backup camera continue to intermittently fail. I have incurred diagnostic expenses and out-of-pocket repair costs attempting to resolve this issue. My concern is that the original recall repair may not have been properly completed and that the same safety-related symptoms addressed by Recall 23V-431 continue to occur, including loss of backup camera functionality while reversing. I am submitting this complaint because I am concerned that the recall remedy was not properly performed and that the safety defect addressed by the recall may still be present.

COMPONENT: Power Liftgate Control Module (PTG module). Vehicle is available for inspection upon request. WHAT HAPPENED: On approximately April 7, 2026, while driving in rain, a "Power Tailgate Problem" warning appeared on the instrument cluster. Following that event, all powered liftgate operation became permanently inoperable — interior button, exterior button, and key fob all failed. CAUSE: An authorized Honda dealer confirmed in writing (service invoice, May 1, 2026): "Power Liftgate Control Unit has corrosion from water leak." The water intrusion originates from defective factory polyurethane seam sealer on the rear drip rail — a known manufacturing defect on 2018-2019 Odysseys documented in Honda TSB MC-10152401. SAFETY RISK: The same water intrusion that destroys the PTG module is documented to cause the liftgate to open unexpectedly while driving, posing a direct hazard to occupants and other motorists. NHTSA is already investigating this issue across 2018-2022 Odysseys. WARNING SYMPTOMS: "Power Tailgate Problem" warning on instrument panel cluster appeared during rain exposure prior to full failure. MANUFACTURER RESPONSE: American Honda Motor Co. declined to cover the repair under goodwill despite the dealer-confirmed defect, an active TSB, and an ongoing class action lawsuit (2018-2021 Odysseys) for this exact issue. Honda has not issued a recall. Estimated repair cost: $691 (module) plus body seam repair.
