I'm having some trouble with 2 units this week. one is a 2015 honda civic,at, pts with evo-one, Thar-one-hon3 with dsm550 smartstart. The other is a 2015 VW golf, key, at, Jan/15, gas. Both worked flawlessly until it reaches its time to timeout and shut down. Set for 15 mins, go outside 35 mins later to find them still running. Cannot shut off with App, oem remote, brake pedal, hood, or key. When stepping on brake or putting key in and trying to shut off, the instrument cluster reads "key system error". The only way to shut vehicle down was to remove fuses/relays related to ignition to stop engine, then unhook battery. Then key operation of vehicle returns to normal. I do not have the service number for the Civic handy as its back with customer. The service number for VW is 002B04 267057. It's almost like its caught in some kind of data loop and cant get out. Any advice is appreciated.
