My brand new Audi Q5 also had engine failure. 3 days old with 110 miles. Started making loud clacking and rattle that increased with acceleration. Had to creep home with engine sounding like ready to blow - glad didn't happen to my wife or daughter driving at speed on highway. Dealer didn't bother to open up and see what specific issue was but said if kept driving could throw a piston. So they ordered a complete new engine - but not from Mexico where mine was built. Awaiting to hear when engine received and how long will take to repair. Have heard the same dealer had another Q5 implode with same issue. Either Mexico workers are taking revenge on us and/or Audi quality control is lacking. I know anything can happen to any car but think Volkswagen/Audi would recognize they have a serious issue on hand.

This is a perfect, all around car for a family that has only one vehicle. The size is perfect for a trip as the trunk is large and can fit enough stuff for a week's time away. The inside is very nice, and everything feels solid. It is extremely fast and quiet on the highway.
