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.

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 Infotainment System in my 2018 Honda Odyssey is malfunctioning, just as is reported by many other Honda vehicle owners. I am experiencing the same issues as others where the speakers are crackling, the audio fails, the screen turns off intermittently while the vehicle is operating leading to the reverse/back-up camera to fail. When the screen is operational it glitches at times (I have videos of the occurrences mentioned). I am aware that a recall was issued in June of 2023 (NHTSA Recall 23V-431) but when I brought my vehicle to Honda Cars of McKinney (Dallas, TX), they said that my 2018 Honda Odyssey did not have a recall of the Infotainment System and charged me a diagnostic fee but returned my vehicle without resolving the issue.

This has been an ongoing issue with the sensors on the sliding door. When closing the door, it would start to close half way, then opens. This makes it really unsafe for children or anyone sitting next to the door as it would open unexpectedly or not close all the way without having to physically pull the door to close. When walking away from the vehicle, sometimes the car would lock automatically (as it should) but there are also times where the door would automatically open when walking away and things has been stolen from the vehicle because of it. The sensors on these sliding doors has been a real safety issue.

In the afternoon hours of [XXX]; my wife, 2 children and I were traveling away from Pageland, SC on [XXX] . My wife was driving the vehicle and hit a pothole on right side of our lane. This caused both driver and passenger side curtain airbags to deploy. Upon exiting the vehicle no visible damage was found other than a leaky passenger side front tire. This incident jeopardized the safety of everyone in our vehicle due to the powder or smoke that comes out causing a visual obstruction of the road, and the sudden unexpected deployment that scared my wife at the exit of a curve. Thankfully, she kept control of the vehicle and did not collide or wreck in to anything. I still called for the North Carolina Highway Patrol due to the incident that happened. The Trooper explained to us that he could not do a wreck report because, there was no collision. He did however do something different and provided us with a copy of it. Due to this, the insurance company totaled the vehicle and forced us to find a different vehicle. I am unsure if this vehicle was inspected afterwards by anyone other than the insurance company. Prior to this incident there were no warning lights or messages stating there was a problem. After the incident, several messages popped on the screen referencing several safety systems on the vehicle and the tire pressure system on the passenger side front tire.

I am writing to formally report an issue with my 2018 Honda Odyssey. I recently discovered water seepage in the rear trunk area, which has caused moisture buildup and potential interior damage. After researching the issue online, I learned that many other 2018 Odyssey owners have reported the same water‑leak problem, indicating that this may be a known manufacturing or design defect. Despite similar complaints, I have not seen any acknowledgement, recall, or official response from Honda addressing this issue. As a long-time Honda customer, I am disappointed that such a significant problem—one that can lead to corrosion, mold, and electrical complications—has not been proactively addressed. I am requesting: An inspection and repair at no cost, as this appears to be a widespread defect. Clarification on whether Honda is investigating or planning to address this known issue. Assurance that any related damage caused by the water seepage will also be covered. I take pride in maintaining my vehicle, and I expect a reliable, defect-free experience from a brand like Honda. I hope Honda will take this matter seriously and provide a prompt resolution

One week ago, I was driving on a highway, accelerating to the 65 MPH speed limit on that road, my van's accelerator completely stopped responding. Despite pumping the pedal repeatedly, I was unable to control my speed at all, and the car continued to lose speed. I had my three children in the car at the time, and given that people regularly go in excess of 70 MPH on that road, I was in danger of not being able to exit the road and/or being hit. I was able to coast off of onto an exit, and the car started responding at speeds of 30 MPH, but it was lurching and jerking while driving. We immediately had the vehicle inspected by an independent mechanic and have been advised that the transmission needs to be replaced. There were no warning lights for this failure. The car also had an incident about a year ago where all lights came on and it stopped responding. At that time, we had Honda dealership examine it, and they said they could not find any issues. Additionally, the car has been jerking slightly while shifting, but the issue improved when we had the transmission fluid flushed at the Honda dealership again about a month ago, and no issues were noted by them at that time. We have performed regular maintenance and safety inspections on this vehicle.

Summary: Engine seized due to internal bearing failure with metal shavings found in oil filter. Full Description: My 2018 Honda Odyssey experienced a sudden engine failure around 116,500 miles. The dealer confirmed the engine is seized and showed significant metal shavings in the oil filter and pan. I have performed all maintenance according to Honda’s recommended schedule using the correct oil and filters. Honda corporate denied assistance based solely on mileage, even though this issue matches symptoms described in current NHTSA investigation PE25-001 (connecting rod bearing failure in Honda 3.5L V6 engines). There were no prior warnings other than a brief check-engine light and rough running before the engine locked up. The vehicle was in motion at the time and could have caused a hazardous stall, serious injury, or death. Given that Honda has issued recalls for similar rod bearing defects in other model years (2015–2020) and this failure mode presents a clear safety risk (loss of power, engine seizure), I request NHTSA include my case in its investigation and compel Honda to extend recall coverage to 2018 Odyssey owners. I can provide dealer diagnostic reports, photos of the oil filter debris, and all maintenance records if needed.

Today I was driving on my road and there are small hills. I was going around a curve i take every single morning and my car kicks really hard as if it is having trouble changing gears. sometimes it makes loud noise. This has been happening for years now and Honda is not addressing it. There is an issue with the 9 speed transmission in these vehicles that have been dealing with recalls. This makes driving scary and my kids are now scared to drive to school in my vehicle. It needs to be addressed as my family is now noticing how much honda has put us in danger knowing these recalls were not really taken seriously.

On [XXX], while driving in traffic, my 2018 Honda Odyssey suddenly and without warning shifted itself into Park. The vehicle slammed to a stop in the middle of an intersection, stranding my family and creating a serious risk of collision and injury. The vehicle would not move afterward and had to be towed from the scene. After the failure, the dashboard displayed multiple warnings: “Transmission Problem,” “Stop Driving When Safe,” “Emission System Problem,” and *“Blind Spot Information System Problem.” The gear shift indicator also blinked. The Odyssey has remained undrivable since the incident. The vehicle is at Stockton 12 Honda in Sandy, Utah, where the dealer confirmed a hard transmission failure (RO #[XXX]). Honda Corporate opened two cases (#[XXX] and #[XXX]). Despite my repeated calls and emails, Honda’s assigned case manager verbally denied coverage on Sept 12, 2025, stating the denial would only be reflected in Honda’s internal case notes. This failure is identical to the defect described in NHTSA Recall 19V-299, in which the Transmission Control Unit (TCU) can reboot due to low voltage and cause the transmission to shift into Park while driving. Although my VIN is not currently flagged, my Odyssey EX-L uses the same ZF 9-speed transmission and TCU as affected trims. I have a tow record, witnesses, and video evidence documenting the event. The vehicle remains disabled, leaving my family without safe transportation. This is a serious safety defect that should require investigation and expansion of the existing recall.

The Auto Engine Idle Stop causes the car to die while at stop lights, stop signs, in the middle of intersections. Etc. when disengaging the AIS the engine stutters and then displays “Shift to Park” then it says to push the brake to start the car but it doesn’t always start up. Sometimes it requires opening the door. Sometimes the collision mitigation system turns off after as well. And the entertainment display turns off or says “No Audio”

As you are driving the car, out of nowhere, you will hear a very loud chainsaw noise coming from the engine compartment that will last a few seconds, immediately after the noise the car seems to roll as if the engine is not in gear or there is no gas going into the engine even though you are pressing on the gas pedal. This has happened around 5 times over the last month. It doesn't happen every time we drive the minivan. This can be very dangerous as you can imagine that when you are pressing on the gas pedal as you are driving at 30, 40, 60 mph, and the car engine just seems to disengage for a few seconds. I took the minivan to the Honda dealership. They first said to change the transmission oil first to see if that fix the problem. They said if by changing the transmission oil didn't fix the problem then they would need to replace the transmission. Within the first week after getting the fluid changed the problem came back. The minivan is now back at the dealership, and I expect that the transmission is going to be replaced. The minivan doesn't have even 50,000 miles yet. No warning lights has shown up. The problem seems to come and go without any warning.

The Auto Idle Stop system causes the engine to stall or fail to restart after being stopped. The error that comes on sometimes says "Collision Mitigation System Problem" on the dashboard, or sometimes "Transmission Problem. Apply Parking Brake When Parked", but either way it happens when I release the brake to drive again after a stop when the Auto Idle Stop comes on. To fix, I'll have to turn off the car and turn it back on.

During rain and snow storms I will get warning lights that the power tailgate isn’t working. Last year when I took it into the dealer they said the tailgate would open and close randomly and there was water in the rear fuse box. I thought I fixed the issue by replacing all the wires from the rear all the way to the front. They fixed my tailgate and did water testing to make sure no water was coming in through the tailgate and all was great. Fast forward to this year and the middle of February we had an all day snow and rain storm and I start having these same warning lights along with a couple others. By the end of the day the tailgate completely stops working. I take it back to the shop that had originally fixed it and water is getting in. Not from the tailgate but through some unknown opening. The fuse board is completely corroded and we have to replace it again. They could not determine where the water is coming in from. I do not want to be driving down the road and have my tailgate randomly open and have items fall on the road causing injury to someone. Nor do I want to have to pay $1000 to fix the circuit board every time it rains or snows. I live in Utah it happens frequently.
