There are several reasons for turbocharger failures. One is not changing the motor oil often enough. Another is running the oil chronically low. Yet another cause is the few drivers who are not happy unless they are in near full boost all the time.
Every turbocharger I’ve replaced did not die a natural death. It was killed by the car owner.
A regional office employee for Subaru did a car transfer one time from TX to OK. In roughly 450 miles he absolutely barbecued that turbocharger just from his driving habits. No wonder he was in a hurry to get to the airport and get out of town. I discovered this problem a few hours later when sales said the car would barely run.
