I bought this vehicle used and before delivery the dealership found oil leaks that they deemed a safety issue and they fixed at no charge.

At what mileage does the engine typically fail?
Based on the 5 complaints filed, engine issues most often appear around 120,377 miles. Some report problems earlier; some make it well past 150,000 with no symptoms. Maintenance habits matter — vehicles that received timely fluid services and were not regularly overworked tend to last longer.
