Hi. What kind of diagnosis and fix did you get from Honda?
I have a 2018 2.0T Accord 6 speed manual. The prev Thursday night I parked in the driveway as usual. Put the stick in 1st gear and applied the electronic brake, The next morning, no start.
When I opened the door, the car flashed the Honda logo on the main instrument panel, but nothing displayed on the central display, and the start/stop button only pulsed a clear/white lights (is not green, red, etc). I initially thought that the battery was somehow drained (it read 12.3V) so just attempted a trickle charge. When the battery read 13.5 off charge, then I really thought that it would start. No difference.
I went thru a bunch of basic checks that I would do on a less complicated car (eg my old 1999 Accord manual tranny), but that led me nowhere. Since this new Accord is so heavily electronics based with a bunch of sensors (ie is the parking brake on?, is the? clutch pressed?, is the brake pedal on, is the next queued song on the USB stick on the annointed music play list?, etc, etc) I had the car towed into the dealer.
By the way, I still have to learn how to deactivate the electronic parking brake when things are screwed up so that other cars in the garage blocked by the broken down Accord may get out.
I called the Honda dealer today (Monday noon) to see what their diagnosis might be. The service rep said that the tech (who actually knows what he tried) had left no details and wanted to keep the car overnight to see how things shake out tomorrow morning. I distinctly have the impression that the tech was driving in the dark (or maybe going by first principles) as to figuring out what the problem may be.
I apologize for the long story, but it is Covid-19 time, and the brandy is pretty good today.
