?I have a concerning noise from my car's engine that I-??ve already brought in for diagnosis. Knocking/ticking/rattling noise on stand-still acceleration at relatively low speeds/under light load. Does not duplicate when revving in park, only under light load. Sound present with HVAC on or off. Does not make noise when cold or after long trips. Honda seems to be aware of this issue and has remedied it through work involving the crankshaft bearings and possibly other components as it relates to their service bulletin 23-097. The problem is that my vehicle falls outside of the stated range of production years as mine is a 2020 model year, but the likelihood seems quite high that the engine in my vehicle is suffering from this exact problem. The service department refuses to help me and the corporate line I've contacted through email me simply refers me to the service department. I just spent $38,000 on this vehicle with 30,000 miles and I have no other recourse at this point to remedy this.

Driving in traffic, switched lanes into a turn lane and came to a stop. The van put itself in park and wouldn't do anything for 5 minutes...the van kept running. It couldn't be shifted out of park, it couldn't be turned off. After approximately 5 minutes was able to put it back in drive and drive away.

My wife was driving our honda odyssey on a state highway and it began lurching and drastically reduced speed while in 65 mph traffic. The vehicle almost created a large accident as it uncontrollably and suddenly reduced gears and instantly slowed well below the rate of travel of the vehicles on the road. She managed to pull over on the side of the road but was unable to move the vehicle. There was never a check engine indicator or any other warning signs prior to this happening. The vehicle was towed to the local honda dealership in Scranton PA. Today the service center there stated that the transmission fluid was charred and burnt up gears in the transmission. This is a huge safety concern as there was no warning signs of the issue until the vehicle rapidly and suddenly shifted down gears and slowed to almost a complete stop along the highway. The vehicle is only 3 years old and is 900 miles over the powertrain warranty. Has there been a check engine light or any indicator we could have had the problem addressed before it became catastrophic and put my families lives in jeopardy. The vehicle has been regularly maintained

My 2020 Honda Odyssey the engine stalled while I am driving. It isn-??t the first time in part two years. My first complaint to the dealer on 2020, the first time my engine stalled when I was moving to the Parking. The engine stalled and all the lights on on the dashboard with a big bang sound. I restarted the car and my car can drive again. I bought it to the honda dealer at puente hills and they told me stop to use the brake hold system while I am driving. After a few weeks later, I have the Same problem again when I made a right turn. After the turn, my car engine stalled again and I almost got rear end from the car behind me. I needed to restarted my car to drive again. After that I drove to other honda dealer at West Covina to check my car and they was unable to find any problems. They told me to take videos when the happenings again. My car was fine for almost two years. My car engine stalled again while I was driving also with the Big Bang sound and all the light on on the dashboard. But I don-??t need to restart my car on this time.because the engine start again after all the lights off from the dashboard. I just need to pass the drive button to move my car. I feel so dangerous. I bought my car honda dealer to check and they told me my throttle have carbon buildup so I paid for them to do it. But I am still feeling unsafe and it-??s a unacceptable situation.

Just experienced a serious issue with our 2020 Odyssey Elite with 24,000 miles on it. Jerked forward from a stop and then would not advance beyond 1st gear. Multiple warning lights came on: check engine/ emissions/ back up camera and sensors. Dealer reported there was an electronic defect that destroyed the transmission which they claim caused the transmission to attempt to shift into two gears simultaneously. Not sure but the jerking motion may indicate that the transmission shifted into park while moving. Dealer refused to provide a loaner car and now waiting for a transmission replacement on a $50K vehicle with 24,000 miles on it. Multiple similar transmission replacements on 2020 Honda Odyssey are reported on the Odyssey Owners Forum. Had this event occurred on a higher speed or congested area a serious accident could have occurred as vehicle could not accelerate and jerked violently initially immediately followed by inability to shift to higher gears.

Upon acceleration from a stop, transmission lags to the point of car not moving. It happens when pulling out into traffic, making a turn or pulling away from a light. Have taken to dealer twice to report..now have 7000 miles on car..dealer says its normal..there is nothing wrong with the car..its the way the transmission works.
