Typical engine symptoms owners report
- Engine stalls or shuts down suddenly at highway speed, sometimes while decelerating or exiting a ramp, with no warning lights.

- Vehicle loses power and cannot exceed a low RPM or speed ceiling, resembling a limp-mode condition, before turbo failure is confirmed.
- Oil separator failure produces a loud whistling sound at idle and rough running, which owners describe as a known issue.
