“Turbo failure and positive crankcase ventilation (PCV) failure. Whining noise from PCV and smoke out the tail pipes with no power. Had to pay out of pocket to remedy issues.”Owner report · Engine · Jan 2022
“Only 43,750 miles and the engine is being completely rebuilt. New cam adjusters, new timing chain tensioners, new timing chain guides... This shouldn't happen on a car with such few miles.”Owner report · Engine · Apr 2019
“I was driving at highway speed when the engine suddenly started to shudder and lose power. The check engine light immediately started to flash and the engine stalled. I was stopped in a busy highway during rush hour. I eventually got the car to a safe location and pulled the turbo air intake to inspect the turbo with a borescope. The bank 1 turbo had damaged itself. This should not happen on a car with only 50,000 miles.”Owner report · Engine · May 2018
