That's bizarre, my 2020 Hyundai Elantra GT N-line (which has most of the same tech as the Stinger) had remote-start via the Bluelink app, in exactly the same way my 2022 Stinger has it. The EGT came with it standard a part of the tech-package and that's the same model-year.aha..you are certainly correct...but while Canada has allowed the UVO app to easily start the car, we southern cousins down here in the USA are sadly not provided the same service online....KIA did make it possible to add the $495 factory option on many of our cars delivered here. Mine had already been added when I picked it up, and it came with that small remote fob along with the usual KIA detonator key, both of which will start my car by clicking the lock and trunk buttons one after the other. But the car stops and beeps the little horn when your time expires, or suddenly when you open the door.
I often find some of the reasons given to be totally bizarre or fictitious. Like for the longest time you couldn't get a remote-start on any BMW 3 or 4 series, they only introduced it with the G20 in 2018. All sorts of rumors would float around that "well, they are made in Europe and it's illegal there". Ok, but then why does the 5-series have it? Why does Volvo have it? Why do all other sorts of cars sold in cold climates have it? It made no sense the way it was explained. This just seems like another bizarre spec decision.
