You bring up a good point, however, how critical is it? Most of the time you are stopped foe about 45 to 90 seconds. Has it lost enough oil to be concerned? The engine warranty is still 100,000 miles so the Hyundai/Genesis engineers are not too concerned.
From a few articles I've read, seems little concern
Now that most new cars have auto-stop/start technology, are our vehicles becoming more vulnerable to engine and component failure?

If the stops on your commute route are all about 45 to 90 secs, then that might work for you. Although, not sure whether I would consider that a good thing or not.
On my own commute route, I don't have that many lights, and I usually try my best to time my approach to minimize having to sit at the light. Still, on average, I would say each light is maybe 10-15 seconds or less, which means 1/2 of them are not worth activating the ISG, if you go by Jason's 7 sec rule.
Still, what irritates most are not those redlight stops, but those very short stops, like arriving at a stop sign with no cross traffic, where I stop for at most a second or 2 before moving. The ISG doesn't know that and would shut down the engine, only to fire it right back up. Even disregarding the wear and tear, I just wasted 5-6 secs worth of idle fuel usage on that pointless ISG trigger. Same thing applies to crawling in traffic. The car doesn't know how long it would be for each stop I make, so it shuts down the engine almost every time even if I'm just creeping forward in stop and go traffic. It gets awfully annoying, and waste more fuel than it saves.
All this, of course, is assuming the wear and tear is negligible. I am sure that is true with each of those ISG firings. I am equally sure that while each firing might be negligible, it isn't nothing. Over time, all those negligible wear and tear will eventually add to something approaching non-negligible.
I highly doubt the Hyundai/Genesis engineers who implemented this system really cared that much about the long-term wear and tear of my engine. This was corporate decision done purely to improve the EPA mpg and emissions ratings of the car, since the test loops are conducted with all drive settings on default. This is why on my
Stinger, as it is on just about every one of these systems, the default ISG setting is ON, and the driver has to manual disengage it, if he/she so wishes.
At the end of the day, if you the owner likes the ISG, by all means use it. I myself will not.
. If you only stop for a second or two, it's actually worse for fuel consumption, the environment, the battery, the starter, and the engine. Plus if you have A/C on, it'd restart immediately, defeating the purpose. I always turn it off on my '22 SF Calligraphy, as part of my start-up routine, along with selecting sport mode. By the way, this is the G70 forum, so I'd move to the GV70 forum, for better answers
