NHTSA Complaint #11450995 — 2014 AUDI A8

Turbos failed. Was traveling home on a highway, when i pulled off the engine suddenly stalls out and loss of steering occurs as the engine system automatically puts you in park. Switching to neutral leads to a very 'leaden'/heavy driving feeling (Kind of like with no Power steering, but a little better). Able to get it restarted again with some effort. Car will stall out at any point in time when RPM is 1200 or less (you have about .25s to get it back out of that range or it stalls again). Power is sluggish. To avoid stalls, shifts must be rapid and neutral-shift+gas needs to be applied to prevent RPM from being below 1200. Made it home safely, but had it towed to dealership. Dealership notified me that it was a turbo failure, both impellers have become lodged in the side of turbo casing and are stalled out. Nothing preceded this; no engine lights or anything. Effect was sudden and drastic. Temperatures were fine. Attempt to drive to repair shop led to total loss of coolant. It is believed this is a seperate issue.
