2018 Honda Odyssey: complete transmission failure

Filed Nov 2, 2026 · Engine · IN

I was driving and my check engine. Light came on, the car was slow to accelerate. I pulled over and I had it towed to a honda dealership, the closest one. They diagnosed it with needing a transmission replacement and replaced a transmission. Then, after the transmission was replaced, suddenly there was a knock in the engine. The dealership sent me a video with them. Revving, the engine very strongly, and I couldn't really discern any knocking noise, but the engine revving was excessive. Then, I asked for an additional video to try and hear what they were hearing. They sent me another video where there was a clear knock. This did not get disclosed to me at all, because they said it was hard to get it into, because it wasn't really accelerating, they couldn't barely get it into the bay after the cart was towed to the facility. If the cart was making a knocking noise at that moment, it should have been noted initially, but it was not noted until after the transmission was replaced. I never had a knocking sound prior to having my car. Delivered to this dealership.

While driving the car lurches as it shifts gears. This had gone on for quite some time but no codes have been thrown. This last time the car lurched so badly at the beginning of acceleration that I thought it was going to stall. It did not, but lights began flashing on the dash and when codes were (finally) thrown I was told I needed a new transmission altogether.

I purchased a 2018 Honda Odyssey and reported during my 7-day inspection window that the transmission was acting sluggish. The Carvana-authorized inspection service (Pep Boys) claimed the transmission was fine. Over time it showed more and more signs of failure until it completely failed. On the directive of the seller (Carvana) and warranty administrator (SilverRock), the vehicle was taken to an authorized Pep Boys facility for a complete transmission replacement. Less than two days after picking up the vehicle, the replacement transmission suffered a complete failure on a public roadway. The vehicle suddenly lost all acceleration and forced itself into 'limp mode' on a highway, and loss of steering control, nearly causing a severe collision. The vehicle is inherently unsafe, and the authorized repair network has failed to provide a merchantable or safe repair, creating an immediate life-threatening hazard.

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.

Bought vehicle new at Millennium Honda, Hempstead New York.Vehicle is not going into reverse when vehicle gets hot. My mileage is 40,512 took it Millennium Honda on October 4, 2025, for diagnostic testing error code P0736 was diagnosed and that my transmission would need’s replacing at a cost of $11,495 for parts and labor, because I was a couple months out of warranty. I have since reached out to Corporate but negative response. I am unable to use my vehicle since which have been at an additional expense to me as I have to maintain insurance and pay for bus, train and taxi services. Not sure what kind of assistance you can offer or even assist in investigating why a vehicle with 40,000 would need a new transmission after moderate use. Thanks for your consideration on this matter.

The main incident was when traveling around 50 miles per hour on a highway, the van shifted into neutral on its own and the accelerator would not respond. An error message of transmission failure showed on the dash briefly. The van had to coast through traffic an eventually push off the road.

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 the federal safety agency 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.

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.
