On 18 January 2023 the tailgate on our 2020 Odyssey refused to open. Neither the inside switch nor the outside switch does anything. I crawled in the back and checked the fuses and both are good. I also discovered that the emergency tailgate release did not function. Took it to the dealer, Greenway Honda in Florence, Alabama, an hour from home, and they weren't able to find the fault with a cursory check and a reboot of whatever computer system is applicable. They said they need to keep it for at least a half day and "really tear into it." But we could not leave the vehicle at that time, having no transportation home. Eventual diagnosis determined the tailgate control module, the tailgate closure motor, and the tailgate latch had all failed. Parts were on backorder and no estimate on availability. After I contacted Honda corporate the parts suddenly became available at the dealership within a few days. Repairs were effected on 27 February at Greenway Honda, Florence, Alabama. We were without the full use of our vehicle for approximately six weeks. Occupants could become trapped in the vehicle if the front doors were disabled in a collision and electrical power was lost, rendering the sliding doors and the tailgate inoperative. The emergency release lever also would not function and this could trap occupants completely. Examination of the tailgate electronic control module shows water infiltration which conceivably shorted the closure motor and jammed the latch, making it impossible to open the tailgate. Photos of the failed electronic module were provided to the dealership and to Honda corporate. The failed parts are in my possession and are available for inspection.

While driving on a surface street at approximately 35 MPH on a 100+ degree afternoon, the glass moonroof suddenly exploded. I did not observe any object striking the car or the roof. The shade was closed, so glass did not enter the cabin. However, driving the car above 30mph became impossible due to air impinging on the shade and making it more likely that the shade would open and glass would fall onto me.
