I don't think powertrain warranties are worth the paper they're written on.
For most modern cars the engine/tranny won't wear out in 100k and if they do the stealership is going to claim abuse and require proof of meticulous maintenance records.
Peripheral engine component, e.g, alternators, ac, electronic fuel pumps, etc ... are far more like to falter before internal engine components, and they are not covered under the powertrain warranty.
KIA and other sub par Korean makes offer 100k powertrain warranties, but I don't see the correlation between quality and length of warranty.
Do they REALLY think the demographics that buy these types of cars will buy a HYUNDAI?
Methinks they made this car to sell to other than us markets. It might do well in other countries. The world doesn't revolve around the US anymore unf.
