Most turbochargers are designed to last the life of the vehicle, much like the engine. You should be able to get 150,000 miles out of the turbo if you take care of it. However, there are some signs that the turbocharger needs to be replaced sooner. If you notice any power loss, whining engine, or exhaust smoke, you might need to have the turbo checked. A failing turbo can also cause the Check Engine Light to come on.
