2010 Audi A6 3.0T Premium quattro 4dr Sedan AWD (3.0L 6cyl S/C 6A)
I love driving this car but sadly have had too many problems.
1) had to replace 4 tires after hitting small potholes for flat/sidewall bubbles. Really detracts from driving enjoyment if constantly worrying about the tires.
2) total of 4 services for coolant pump, 3 engine related repairs - broken fan, loose lines, and rear view mirror falling off.
