Seems about the same for others that are in the "engine replacement" status.
The genesis coupe has been out of production since 2015/2016 so the factories aren't making the rwd 2.0t engines as much as they use to.
I doubt they cracked it open to see what seized. If it's a connecting rod, then it would be just replacing the crank, pistons/connecting rods, and bearings.
If it's a main bearing, then it would the same, but the block would have to go to a machine shop, the journal bored/honed, and an oversized bearing put in.
This would be faster, but since techs at dealerships are paid by the flatrate system, they don't what to sink that much time in doing that, and doubt hyundai has a pay-rate for those kinds of services on their books.
Flatrate - what this means is, instead of mechanics getting paid hourly, the auto manufacturer has a "book" or system that state how long a certain service should take to do, and a mechanic gets paid that amount.
So if a mechanic can get, say a wheel bearing, replaced in X hours, and he/she gets it done faster, then they can get paid more for their time.
They get paid hourly, but that is for just being an employee of Y dealership.
