Engine, Mar 14, 2025
On this 2018 Honda Odyssey, at 93000 miles, an abnormal noise started to occur under acceleration. Dealer diagnostic indicated the noise is coming from the bottom end of the engine, likely from the rod bearings. The dealer indicated that this specific VIN number is not included in the current Honda recall, however is exhibiting same symptoms.
Forward collision avoidance, Lane departure, Mar 13, 2025
The front facing monocular camera has failed and my 2018 odyssey has less than 55k miles on it. Without the operation of this camera you cannot use the cruise control and the dash lights up with all kinds of warnings (lane mitigation failure, acc failure, brake light continuously on). This is a known faulty safety feature that is far to common for the newer odyssey models. This is ridiculous that Honda has put this system into their vehicles, in particular the odyssey and there needs to be a service bulletin to repair this issue or recall completely. It is obviously a faulty part and needs to be resolved.

My 2018 family van purchased brand new. Exclusively serviced at dealer. Immaculately maintained records kept. Driving 70 mph on toll road while driving to dealer for service, car lost power and had to be towed remainder of the way. 100k service done at dealer, 40k miles later car had to be towed back to dealer due to broken rods. Honda says my vin# not effected yet car is inoperable for exact issue with open recall effecting rods. Recall states cars effected produced 2015-2020. Honda offered for us to pay $10k for new engine and they would cover remaining $4k. We do not believe we should get stuck with larger portion of payment when Honda has a known issue with part. Research on line states many more cars affected than the 250,000 initial recall. We appreciate NHTSA’s 2nd probe into this issue.
Forward collision avoidance, Lane departure, Mar 10, 2025
2018 Odyssey Elite with 43k miles. Apparently, the front facing camera failed and if the camera fails -- which seems to have been reported by many other owners -- it's about a $1700 fix from a dealer. Not only should the camera not fail, but this is happening to cars that are low miles, low use, and the failure affects all camera-related safety features of the vehicle: lane keep assist, adaptive cruise control, lane departure warning, forward collision warning, parking collision warning, and automatic emergency braking.

Power train, Mar 4, 2025
My 2018 Honda Odyssey experienced a heavy snowfall in January 2025. The control panel displayed an alarm, Power Tailgate Problem , and the trunk door could not be opened. I asked a professional who pointed out that it is usually due to water intrusion into the control unit located on the rear driver's side body panel, which causes the tailgate to fail to open, close normally, or even open accidentally. They believe that this is a manufacturing defect caused by the manufacturer and there is a safety hazard. For safety reasons, I went to the dealer for an inspection. They said they could not find the cause but that the control panel was broken and needed to be replaced. I had to spend a lot of money to replace it. But I still think that the problem was caused by the manufacturer itself.

There is a major safety issue that has happened a few times now. As I come to a stop, or come out of a stop, the engine stutters and completely shuts off. All electronics stop too. Immediately there is a message flashing “right sliding door problem.” I have to put my foot on the brake and restart the engine to get going again. This recently happened as the red light turned green, and a car almost slammed into me from behind.

My car has had all recommended service completed by the dealership since I purchased my Honda Odyssey in 2018. On 2/18/25, my power liftgate started malfunctioning. An error message beeps inside my car 4 times, every 4 seconds and cannot be manually turned off. I took the car to the dealership and was quoted $7500 to make the repair. My car only has 90,000 miles on it and has passed all of my previous service inspections. Supposedly, water is getting into the rear control module. I have never had water in my car so this is clearly a manufacturer's defect that is allowing water to seep into the rear control module.

Engine, Fuel/propulsion system, Feb 14, 2025
I took my 2018 Honda Odyssey to the dealership for a fuel pump recall repair. The next day, the engine warning light turned on, and I heard a loud abnormal noise from the high-pressure fuel pump.I scheduled an immediate service appointment. The dealer charged me $230 for a diagnostic but claimed no fault or error code was found. They turned off the warning light without explaining why it was triggered.The abnormal noise from the high-pressure fuel pump persisted, and the dealer recommended replacing the high-pressure fuel pump for $1,942.78 while denying any connection to the recall repair. Component/System That Failed: High-Pressure Fuel Pump Engine Management System How Was Safety Put at Risk? A fuel system failure can cause engine stalling, leading to sudden loss of power while driving and an increased risk of a crash. Has the Problem Been Confirmed by a Dealer? Yes. The dealership acknowledged an abnormal noise from the high-pressure fuel pump but denied any connection to the recall. They only reported a DCA-8000 code, which is not a standard fuel system error code. Has the Vehicle Been Inspected by the Manufacturer? Yes. The dealership inspected the vehicle but refused to take responsibility. Honda Corporate was also contacted, but they denied warranty coverage. Any Warning Lamps or Symptoms Before the Failure? No prior issues before the recall repair. The engine warning light turned on the next day, and the abnormal noise from the high-pressure fuel pump began immediately after. Why This Needs to Be Investigated: The issue began right after the recall service, suggesting a possible defect. The dealer charged me $230 but failed to explain the warning light activation. If other vehicles experience this, it may indicate a recall defect. A fuel system failure can create serious safety risks for drivers and passengers. NHTSA must investigate whether the recall service contributed to high-pressure fuel pump failures, as this could pose a significant safety hazard.
Power train, Fuel/propulsion system, Feb 12, 2025
In several occasions there is a delay in acceleration. This typically is happening when I take off from a stop sign and turning, others I have literally been on highway merging and loss all acceleration Al though I can hear rpm ramp up, there is no action till 10-15 seconds later. I am very lucky no was injured in that instance and could have been a terrible accident going 70+. I see this is an ongoing issue, and because it is not consistent in manner people fail to repair/research issue.
Air bags, Feb 10, 2025
The airbag system malfunctioned, causing the airbags to deploy unexpectedly while driving. The vehicle is currently at the Honda dealer for repairs and the airbags, as well as related components, are available for inspection upon request. The unexpected deployment of the airbags posed a significant safety risk. It startled me, which impaired my control of the vehicle suddenly as I was driving on the highway. Afterwards, I noticed fumes in the vehicle and I began feeling nauseous and light headed. I managed to pull over on the highway and stepped out of the vehicle. This could have led to a loss of control of vehicle, increasing the risk of collision or injury to not only myself but others on the road as well. The problem has not been reproduced or confirmed by a dealer or independent service center yet. However, my insurance appraiser inspected the vehicle immediately after the incident and confirmed that the airbags deployed without any signs of a collision or impact. The cause of the deployment remains unknown, and the appraiser recommended that Honda investigate the issue further to identify any potential malfunction in the airbag system. The issue has been inspected by my insurance appraiser, who concluded that while the airbags deployed, there were no visible signs of a collision or any impact that would typically trigger airbag deployment. The inspection of the vehicle’s exterior panels, undercarriage, and suspension showed no signs of damage. The cause of the airbag deployment is unknown, and the appraiser recommended that Honda investigate further to determine if a malfunction within the vehicle’s airbag system is responsible. I believe Honda is at fault, as this issue appears to be related to a malfunction that they need to address. There were no warning lamps, messages, or symptoms prior to the airbag deployment. However, after the airbags deployed, warning lights appeared on the dashboard, indicating a potential issue.

The Tailgate Control Module (TCM) was infiltrated with water due to a crack in the seam on the rear driver side panel. This caused the tailgate to be unusable and no longer latch as a result of no power to the tailgate latch. The TCM (Part #: 74970-THR-A12) had to be replaced as well as all seams needed to be sealed.
Engine, Jan 24, 2025
The vehicle has recently and suddenly developed a loud engine knocking sound which sounds like an engine bottom-end knock (crankshaft or connecting rod). The sound is dependent upon engine RPM and is most noticeable at low RPM and when the engine is warm. The knocking sound is severe for the first 1-2 seconds on cold engine start, until oil pressure is developed. There are two known incidents believed to be caused by this issue: 1. While driving on a public highway with a 75 MPH speed limit, the engine knock became severe and the check engine light began flashing. The car would not accelerate, and once speed was reduced it would not accelerate at all and "limped" home at much-reduced speed. Prevailing traffic had to take action to avoid colliding from behind. 2. While driving up a very slight incline on a public highway with a 65 MPH speed limit, the engine knock became severe and the check engine light began flashing. The engine was unable to produce power and struggled to climb the hill at around 33 MPH with prevailing traffic coming up quickly and swerving to avoid colliding. The vehicle "limped" home again. The problem has been confirmed by an independent service center specializing in Honda and Acura vehicles, and confirmed that the knocking sound does indeed sound like a connecting rod and referred me to Honda service bulletin 23-097. I called American Honda to inquire as to whether my vehicle's VIN qualifies for the associated recall, and they said the vehicle does NOT qualify, and that it was a very narrow range of VINs which do qualify. The vehicle has not yet been inspected by the manufacturer, police, or insurance, only the independent service center who did NOT open the engine bottom end for inspection, only listened and did non-invasive troubleshooting before referring me to Honda. Please add this to the Office of Defects Investigation's investigation RQ24013

Emission error code which is part of recalls due to Fuel pump and suddenly check Egin light came on and vehicle couldn't shift from Park Mode to Drive Mode. We took the vehicle to Dealer ship and they mentioned that transmission failure where vehicle just two weeks ago at the dealership for another repair and inspection report didn't specify anything about the transmission.
