POWER TRAIN, ENGINE, FUEL/PROPULSION SYSTEM
Our 2018 Honda Odyssey repeatedly and without warning completely loses acceleration power, creating extremely dangerous driving conditions. This occurs in two distinct situations:(1)while driving at highway speeds when attempting to change lanes or accelerate, and(2)when stopped at a stop sign or intersection and pressing the gas to merge into or turn into traffic. In both situations, pressing the accelerator results in little to no response — the vehicle will roll but fails to accelerate as needed. These failures have placed our family in multiple life-threatening situations. On Interstate 285 in Atlanta, Georgia — one of the busiest and highest-speed highways in the country — our vehicle has failed to accelerate during lane changes on multiple occasions, nearly causing serious accidents. Most recently, within the past week, my husband was driving on I-285 when he pressed the accelerator and the vehicle had absolutely zero acceleration response. He narrowly avoided a collision. We have also experienced complete loss of acceleration when turning from a stop sign into traffic and when merging — situations where immediate acceleration is critical to safety. The vehicle lags for several seconds before any power is delivered to the wheels, leaving us dangerously exposed in oncoming traffic. All manufacturer recalls have been completed, including the fuel pump recall. The problem persists and has not been resolved by any dealer service or recall repair performed to date. We are aware that this is a known, widespread defect affecting 2018 Honda Odysseys equipped with the ZF 9-speed automatic transmission. Hundreds of other owners have reported identical symptoms to NHTSA and to Honda directly. Honda has acknowledged the transmission's behavior to some owners but has stated it is "how the car is supposed to drive" — a response that is wholly unacceptable given the documented near-accidents this defect is causing.We are requesting that NHTSA open or expand its investigation

SERVICE BRAKES, STEERING, FORWARD COLLISION AVOIDANCE: WARNINGS
While driving on a clear road, with or without heavy traffic, the collision mitigation warning shows up on the dashboard display. Sometimes the warning for the collision system goes off and the system tries to brake and jerk the wheel. If I have the wheel firmly I can correct it and it resolves. It can happen on a clear road with no one around or in heavy traffic. Yesterday it happened in a single lane with barriers on both sides, a road around Logan Airport in Boston, with no vehicles ahead of me. The car tried to steer me into the barrier. I was doing less than 25 MPH. The warning had been going off for a while but now that the steering and braking are involved it’s much more serious. I reported it to the dealer. They said they did a system check and couldn’t find a fault. The braking and steering problem first occurred about a month ago. The warning by itself has been happening intermittently for over a year. This happens even when the collision mitigation system is turned OFF. This is a terribly unsafe issue. If my wife had been driving I don’t know if she could have corrected. PLEASE ACT AND ISSUE A RECALL!

POWER TRAIN
I am reporting a dangerous and recurring transmission defect in my 2018 Honda Odyssey equipped with the ZF 9-speed automatic transmission. The vehicle experiences sudden and unpredictable delayed acceleration, particularly at low speeds. When attempting to accelerate from a complete stop or at speeds below 25 mph, the transmission fails to engage properly, leaving the vehicle stranded in the middle of traffic with no power response for several seconds. This creates an extreme safety hazard, as other vehicles may collide with mine while I wait for the transmission to respond. The condition is intermittent and unpredictable, making it impossible to anticipate when it will occur. It happens most frequently when accelerating from intersections, merging into traffic, or navigating through slow-moving areas. Honda has acknowledged this defect through TSB 19-124 (issued December 2019), which addresses harsh and jerky upshifts in 2018–2019 Odysseys with the 9-speed transmission. However, the TSB does not fully resolve the issue. A class action lawsuit [XXX] et al. v. American Honda Motor Co., Case No. 5:23-cv-05011-BLF, N.D. [XXX] ) is currently pending for this exact defect. I am requesting that NHTSA open a formal investigation and consider issuing a safety recall, as the delayed acceleration constitutes a serious risk of collision and injury.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, FORWARD COLLISION AVOIDANCE: WARNINGS
our honda odyssey 2018 elite - has a failed windshield monocular camera - original part (36160 - THR - A73) failure is a u3000-49 error. This failure causes most of the advanced safety features of the vehicle to not be operational. see these dashboard errors: Collision Mitigation System Problem Road Departure Mitigation System Problem Auto High Beam Problem Adaptive Cruise Control Problem Current repair cost from a dealership can exceed $2000. I've researched many forums and this seems to be a very common problem among Honda Odysseys of similar year range. I fee like Honda should issue a recall and replacement for owners since this involves many of the saftey features of the vehicle and cost is very prohibitive to fix for many of us.

The roof leaks in the LH rear of the van under the roof strip thru a bolt or bad seam rfom a bad build causing the Power Unit Liftgate Module PN - 74970-THR-A11 to get wet and sit in water causing a short to the battery, The sliding doors to fail and the rear liftgate to fail which is a safety hazard if someone cannot exit the vehicle in an emergency. It is also a fire potential. This should be a safety recall at Hondas expense. The world wide web is flooded with videos and forums pertaining to this exact issue and Honda has not stepped up to the plate and addressed this issue.

ELECTRICAL SYSTEM
Rear hatch power door issue indicated on dash display, and complete failure of powered door feature. Investigation finds many other drivers of this make/model/year have issues with faulty seals allowing water intrusion into circuitry in left rear panel where the power lift fat control unit box is, causing damage to the circuitry. Other drivers have described more widespread electrical issues, some even causing the gate to unlatch while the vehicle is in motion. Upon inspection of my personal vehicle, signs of water damage were found both in the base of the area covered by the panel and within the circuit box and panel itself, confirming these suspicions.

UNKNOWN OR OTHER
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

FUEL/PROPULSION SYSTEM
My Odyssey began to shudder and misfire. Luckily, I was in a parking lot when it happened. It stopped running. Several attempts to restart were unsuccessful. Once when it did start, it was missing and would barely move. After about 15 minutes, I was able to get it started and get home (a little over 2 miles). I installed my code checker to find the problem. I initially had 22 codes - including P0301-P0306, P0300 and P0087. I waited a while and re-ran the test. The P0087 continued to show. I did not attempt to drive it anymore until the next day, when I took it to Canady & Branch (Auto Repair). They checked for codes and also had the P0087 code. They called and informed me of the issue and indicated that it involves the fuel pump. They also indicated that there were recalls for the Honda Odyssey for the fuel system:fuel pump. I contacted Priority Honda to determine if this would be covered under a recall. I was told that the recall did not involve my Odyssey. I needed my vehicle, so I had Canady & Branch make the necessary repair ($874.42 - the diagnostic was an additional $77). I spoke to Honda USA today and was informed that they do not cover 3rd party work and reiterated that my vehicle was not on the recall list. I was told that IT HAD BEEN on the list but was removed in March of 2024.

ENGINE
Our 2018 Honda Odyssey (Elite) has been diagnosed by our local Honda dealer with engine failure due to rod knock (rod bearing failure). This vehicle is well maintained with only 72,500 miles when the issue became noticeable. The dealer has verbally quoted $8,800 to replace the engine with another used engine, which I refuse to pay given the relatively low mileage and age of this vehicle (and history of other costly inexcusable issues). I opened a complaint/goodwill case (#16188784) with Honda Corporate, which was denied. This Honda Odyssey was our primary family vehicle (the only vehicle we can all travel together in), and it is now siting in our garage completely inoperable. Honda America's lack of care here is beyond frustrating.

ENGINE
While driving on the highway, the engine light came on and off. Pulling over, I inspected the engine compartment and heard what I believe was cylinder knocking, but could not obtain an engine code with an OBD code reader. Oil was of sufficient level as it had just been replaced within 1,000. After this I attempted to drive it to the dealership, where on going 45 MPH, I pulled to the right lane for emergency police vehicles and when the vehicle was stopped, the engine stopped and seized up. After not being able to start the vehicle, I could not find the neutral safety switch to put the transmission in neutral to move the vehicle from the flow of traffic (turns out the switch is not readily accessible and is on the side of the transmission underneath the air intake and battery compartment. Police officers pulled behind the vehicle and assisted me in getting a tow truck to take the vehicle to the dealership for inspection. At Coggin Honda in Jacksonville, the vehicle was inspected and the engine would not turn over manually by the crankshaft. The engine was deemed to have catastrophic failure and would need to be replaced at 126,000 miles. This vehicle is a 2018 which is on TSB 24-003, however is not listed on the applicable VINs. This TSB is for connecting bearing rod failure which would lock this vehicle’s engine the way the dealership found it. I believe this to be the issue as several Honda engines have had this failure. The vehicle was maintained per Honda’s maintenance programs and even had an extended warranty of up to 100,000 miles which when the TSB the vehicle was underneath that mileage and would have been covered by Honda if they had released the full list of VINs for that year to be inspected instead of a sub list of VINs of the production. Honda needs to be investigated to see if that TSB needs to be expanded since 2023-2024 timeframe other users have had a similar failure and seized engines.

2018 Honda Odyssey rear tailgate problems, What was the issue? Problem is because water is leaking from the roof rails onto the tailgate module, causing the power liftgate control unit to short circuit, leading to unintended opening/closing or complete failure.I checked every fuse and my tail gate still wont open! tailgate module failed due to leak on the roof rail. The "holes" are three very small spots that the weld didn't cover.......

FORWARD COLLISION AVOIDANCE: SENSING SYSTEM: CAMERA
The contact owns a 2018 Honda Odyssey. While driving at an undisclosed speed, there was a loud sound coming from the vehicle with unknown warning lights flashing on the instrument panel. The vehicle was drivable during the failure. On another occasion, the brake warning light flashed on the instrument panel, and the brakes slightly depressed independently, and the driver then fully depressed the brake pedal. The vehicle was taken to an independent mechanic, where it was diagnosed with a monocular camera failure. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 125,000.

VEHICLE SPEED CONTROL, ENGINE, UNKNOWN OR OTHER
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.

ELECTRICAL SYSTEM, LANE DEPARTURE: ASSIST, FORWARD COLLISION AVOIDANCE: WARNINGS
Upon further investigation, LOTS of 2018 Honda Odysseys are experiencing the same problem I am. There is a leak coming in from the top of the van in the rear that causes water to leak through and overtime damages the control unit in the back. Damage to this causes my power lift gate to completely stop working, my passenger drive door to stop working, and a bunch of features like the front collision warning, the lane departure, sensors, fog lights, so on to fail and go on and off. I had problems here and there with it but it wasn’t until it rained 4 days straight that I made the connection with the leak and started trying to figure out the problem. I took it to the Honda Dealership to get diagnosed and they confirmed this problem. We have not been in any accidents to cause body damage to the vehicle.
