Engine Knocking Noise problems of the 2015 Hyundai Tucson

I bought this car as a lease return at 36k miles. I have taken it in for all the recommended services and also the oil changes at the recommended intervals. Never had an issue with the vehicle at all till now. At just over 70k miles I was driving at 75mph and the engine lurched and the vehicle went into limp mode. The fastest I could go was 60mph. The engine had a wicked knocking sound. Fortunately I was near a Hyundai dealership so I took it there. They said it needs a new engine. Thankfully I have the certified pre-owned warranty on the engine & powertrain up to 100k, so Hyundai is eating the cost. But it is still wildly concerning to me! I'll for sure be selling this car before it hits the 100k warranty.

I've done my regular maintenance on this vehicle since I've purchased. Drove to two places today, after second place on start up oil light came on with very loud engine knocking. Checked my oil to find none on the dipstick, filled back up with recommended oil and some of the noise went away. Still has very profound knocking noises in the engine block with lack of power. Bought this vehicle with 44,500 miles now has 50,500. Shouldn't have any trouble at this mileage at all. Taking to dealership to see what will be done. This vehicle has common problem but no recall for this particular vehicle.

Driving vehicle where felt hesitation accelerating. Then heard a banging noise where engine had seized. This is first new car owned what a disappointment. This problem is known through Hyundai and they have done nothing about it. My advice stay away.

2015 Tucson engine blew after only 70,000 miles. It did not show any signs of failure but as I was driving the engine made a bang noise and just stopped and would not start again. After I did some research I found out that this is not the first Tucson to have engine failure after 70,000 miles.
