Was driving down the freeway when the check engine light went on. I tried to pull over but car lost power and I heard a loud bang noise. Smoke came from the engine and the car stopped in the fast lane. Luckily i was not hit by any other cars. Once we got the car towed you can see a hole in the bottom of the engine. these 2017 hyunadi santa fe’s have crankshaft failure, we even received a letter from Hyundai stating this.
