2026 Honda PassportRecalls, problems, MPG & safety

“Like many others have reported on the internet, I am now seeing the TT04 message on the dashboard inidicating that a software update was interrupted and I must see the dealer. This is concerning in that this bug has been reported for years and Honda has failed to find a solution. What exactly is not working in the car with a failed update?
