2019 Honda Odyssey Transmission and drivetrain Problems

“The 9 speed transmission jerks and bangs while moving. Driving from slow speed the car jerks and stalls. At hwy speeds the car bangs very hard - it seems like it is being bumped. We thought it stalled at hwy speed after it banged very hard. Honda service says they cannot find problem. We have been driving car for 2.5 years - and the issues are getting more frequent and harder.”

“Vehicle jerks at about 25mph when it’s idled in 1-2rpm. Sometime at acceleration and won’t move up rpm. Vehicle got fuel injectors and transmission fluid replaced and still have issues. Vehicle in shop now with less then 2,000k before power train warranty up even though I’ve been dealing with it for over a year. Dealer said transmission fluid was down quart 4 months after they changed the transmission fluid. They were able to replicate jerk but couldn’t replicate sound of something clicking over while idle. I have it on video. …”

“I was driving my 2019 Honda Odyssey up a slight incline and then suddenly I lost all power. The minivan automatically put itself in neutral and the dashboard screen switched between saying, stop driving when safe. Transmission problems. See manual and transmission problem.

This is to such a level that the vehicle cannot engine brake itself. You absolutely have to hit the brakes because it will not slow itself down. So, when coasting down a 6% and steeper grade with no accel pedal at all.....the transmission does not gear down on its own at all. It will free wheel. Which is fine. …”

“The vehicle down shifts to a lower speed during travel. It occurred while driving 45 miles/hr, at 70 miles/hr and when the vehicle is on cruise. First time it happened I thought the transmission broke. It was in the middle of the traffic. A couple of messages popped on the dash, 'transmission system problem' and 'blind spot info. System problem'. I pushed the reverse button it was inactive, neutral was working. Took the car into a parking lot and called the dealer. Dealer asked if I turned the engine off and on. I did that and the issue went away. …”
