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.

Honda issued a recall on the fuel pump December 2023. They did not have any parts available to replace mine. I had brought in my Odyssey Elite to Space Coast Honda multiple times before the recall stating my engine wouldn't crank. I was unable to get the fuel pump replaced until December 5, 2024. ONE YEAR after the recall. I am now getting Emissions System Problems and Stop Driving When Safe Engine Temperature Too Hot. The dignostics that were pulled were P219A Secondary P219A, P0420, P219A. Also, my intake manifold gaskets are leaking coolant. I have had nothing but problems with this van since April 5, 2023 with my car not starting and stalling. My kids and I were stranded at their school two times and there were multiple times at my work. I don't believe I should have to pay thousands of dollars for these items to be replaced since I believe they're an issue due to me driving on a faulty fuel pump. I even called Honda Customer Service multiple times and they told me to keep driving it even though I expressed concern for my kids and having been stranded multiple times. Both dealerships said there was nothing wrong even though I brought it in multiple times for the same issue.

The seam seals on the rear driver's quarter panel of the vehicle are faulty and allowed water to flow into the cabin of the vehicle. The resulting damage was loss of function to the rear power lift gate, front seats, remote start and other key fob functions, as well as a dead battery(assumedly due to arcing on wet circuitry). The damage rendered the lift gate inoperable as I it initially closed but came open during operation. We continued to receive a power lift gae problem on the "Heads Up Display" but the power gate would not open or close, electrically or manually. After a few days the gate opened but would not close, rendering the vehicle unsafe to operate. Furthermore, the battery was dead and would not start. Had this incicdent not occurred in our driveway we could have been susceptible to being stranded in sub-freezing temperatures with kids. The vehicle was taken to a dealer and they confirmed a roof leak was a cause of the water incursion. The power lift gate module and floor harness were damaged causing failures to lift gate operation and other electronics. It will cost $7000 to have it repaired at the local Honda dealer. Pending completion of repairs and paperwork for submission.

This vehicle has had numerous electrical issues, culminating in the need for three batteries in a six year. Period. From day one there were electrical issues with the auto stop start and the car in one occasion the battery completely died. Honda was unable to identify the issue and electrical issues. Continue to happen. in the last 18 months I’ve had numerous occasions where this auto stop start would engage at a stoplight stop sign in the middle of busy traffic, but would not start back up. I took it in for service and they cannot re-create or identify the issue. This is very scary when it happens as I have been on start and go traffic on the interstate on busy intersections and the car will not move nor can it be restarted for 5 to 10 minutes. Honda offers no solution to this dangerous problem. After months of not being able to fix this. Identify a problem the car no longer moves into reverse consistently Honda recommends new transmission.

When the vehicle’s auto start-stop feature is active, the feature will malfunction causing the engine to not start properly. Instead, the vehicle stalls and must be restarted manually. However, there are many occasions when the vehicle does not start manually either. In these cases, it takes many attempts to restart the vehicle. While these events are happening, the vehicle displays an error message for the auto start-stop feature on the instrument cluster, and the instrument cluster will flicker on and off. The events often occur during the middle of an intersection and attempting to turn in front of oncoming traffic. It creates a very dangerous situation. the vehicle or component has not been inspected by the manufacturer, police, insurance representatives or others because the issue occurs regularly, and the dealership has asked us to come back when the problem is occurring. The problem has not been reproduced or confirmed by a dealer or independent service center. However, there are other Honda vehicles (e.g., Honda Pilot) which have the exact same issue, and a recall has been issued for those vehicles but not the Honda Odyssey.

several times when stopped at a light, the vehicle's auto idle engine engages and shuts the car off. When the brake has been released, the vehicle has failed to start. Most recently, this occurred while waiting in a car line of traffic and it took many different attempts to get the car engine back on - about 10 minutes before the engine could be started, resulting in myself and my children stuck on the road while we opened doors, the hood of the car, tried to start the car and turn it completely off. It was in a stuck position until it wasn't. that was the first time the vehicle wouldn't start after numerous attempts to start the engine. We have been told there is no way to fix this - only to manually turn the function off every time the car is started.
