It's a matter of semantics, but I object to saying a braking system isn't purely brake by wire when electronics alone can cause it to totally fail. There's a difference between a fail-safe that usually works, and a mechanical connection that's always there. Electronics can fail in many interesting ways other than simply turning off. And they do! Ever looked at nhtsa.gov? "Brakes Failed problem of the 2017 Honda Accord Hybrid Failure Date: 10/31/2018 There have been three instances of total brake failure. Initial instance occured on vehicle startup, a number of errors were given including "aadaptive cruise conrtol problem","collission mitigation system problem","road departure mitigation system problem" and "brake system problem". When I put the car in drive it immediately began moving forward. Car was towed to dealer where Honda blamed the issue on the undercaoting causing components to overheat. This was October 2018 in philadelphia. Replaced brake system and removed undercoat on affected areas. Second instance occured in February 2019 it had stopped raining but road was still wet and had puddles. Driving downtown, at a yellow light brakes completely failed, I ran the light and was able to stop with emergency brake. Car was giving the same set of errors. This time restarting the car made errors go away. Brought to the dealer, they said they did a software update but could not replicate the problem so did nothing else. Third instance was February 2nd, while driving about 30-40 mph, again either after rain had stopped or still had a slight drizzle. This time I saw the errors while driving before I needed to break and recognized the issue. Managed to use emergency brake to pull over. Again restarting the car cleared the issue, I have not brought back to the dealer yet."
