I have a keyless system problem light that intermittently comes on. Never on the day I schedule service of course. Yesterday while driving I heard loud clunk and felt a jolt accelerating to aprox 25 mph. Once past that speed it didnt happen but all the way home any time I had to stop at a light and start again, same thing happened. Anyone have same issue. Vehicle has 113K miles and just ran out of extended warranty.
Maybe a little bit of a late reply, but the keyless system light on mine turned out to be the start button going bad - replaced and no problems with that since. There was a lady with an accord at the dealer same day as me with who had the same issue and fix. I think I paid around $250 at the dealer, but I didn't have time to research, test & fix it myself.
Also, there is a TSB on the 6-speed transmissions. Mine is a 2017 as well and was covered under the TSB. It includes a software update, draining / replacing the transmission fluid, and road test. No problems since then.
I can look up receipts later if this is still relevant to you.
