ELECTRICAL SYSTEM
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
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.

FUEL/PROPULSION SYSTEM, ENGINE
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.

FUEL/PROPULSION SYSTEM, POWER TRAIN
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
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.

FUEL SYSTEM, GASOLINE
The contact owns a 2018 Honda Odyssey. The contact stated that when the vehicle was started, there was a loud vibrating sound coming from the engine compartment. The contact stated that when the vehicle was shifted into drive(D) and the accelerator pedal was depressed, the sound was louder. Additionally, the vehicle lost motive power during acceleration for approximately 10 minutes and then drove normally. The vehicle was taken to a dealer where it was diagnosed and determined that the high-pressure fuel pump needed to be replaced. The vehicle was not repaired. The vehicle was taken to an independent mechanic for a second opinion and the contact was informed that the high-pressure fuel pump needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 17,163.

The contact owns a 2018 Honda Odyssey. The contact stated while driving 70 MPH, the vehicle lost motive power and failed to accelerate as intended. The check engine warning light was illuminated. The vehicle was then steered over to the side of the road and restarted; however, the failure persisted. Additionally, the contact observed a knocking sound coming from the engine compartment. The vehicle was taken to the residence. The vehicle was then taken to a dealer where it was diagnosed that the control rod had fractured, and the engine needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 144,000.

UNKNOWN OR OTHER
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.

ELECTRICAL SYSTEM
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
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

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, FORWARD COLLISION AVOIDANCE: WARNINGS
Regularly maintained my Honda Odyssey Elite. Suddenly get warnings for all safety elements while driving - adaptive cruise control, Lane keeping assist, collision mitigation system, road departure mitigation system, auto high beam headlight. Recommended to report as this seems to be a common thing with Honda and needs to be a recall. Dealership wants me to change out the radar sensor in the front which seems to be the root cause. Lots of other Honda Odysseys having the same safety issue as reported on NHTSA website.

STRUCTURE:BODY
Our 2018 Honda Odyssey has continued to experience power sliding door issues that were initially addressed by NHTSA campaign numbers 18V795 and 20V437000. Our vehicle underwent the recommended repairs in both campaigns. The vehicle is available for inspection upon request, and the problem was reproduced by a dealer. In short, after undergoing both warranty repairs, the same problems gradually cropped up again. When attempting to close the door with the power-close button, the sliding door would sometimes stop about three-quarters of the way, and then open fully again. This would happen even when nothing was obstructing the sensor. This happened on both sides of the vehicle (i.e., both sliding doors), and eventually the doors ceased working altogether (albeit at different times) and we brought the vehicle to Honda for a non-warranty repair. The dealer was able to reproduce the problem in both doors, and they made the necessary repair in both cases (see attached invoices). Now, very similar issues have cropped up again, and our concern is that the initial warranty repairs may not have sufficiently addressed the root cause of the issue with these sliding doors. Once again the door sounds like it isn't latching completely. It's hard to describe, but everyone knows the sound in a vehicle when a window or a door is cracked just a little bit. The sound is exactly like that. The dealer told us that moisture intrusion and/or a latching issue may have caused this problem, and we also experienced a severed cable. Word for word, these are almost exactly the issues that campaign numbers 18V795 and 20V437000 were intended to address. If these are indeed the same issues that were the focus of the two recalls, then our vehicle is at risk of the same safety failures, i.e., the sliding doors opening while driving, failing to latch, and/or the snapping of the outer door handle cables due to moisture intrusion.
