Loss of acceleration. Errors. Turbo failure before 3,000k miles. Received five errors alerts at once: 1. Emergency assist not available 2. Engine speed max 4000rpm 3. Error: drive system currently unavailable 4. Error: cruise control system 5. Travel assist currently unavailable. Initial occurrence was misdiagnosed at dealership as a computer system failure. They cleared the alerts but not the problem. Returned to service a second time (currently there) and they identified the turbo needs full replacement and it is not safe to drive. No eta on a fix “due to parts back ordered”; potentially mid-March.
