Based on the evidence I've seen Audi is doing ok, though they could of course do better. The A4 seems about average. The 2012 A6 is doing pretty well so far, but it hasn't been on the market that long yet. Traditionally the A6 is Audi's most reliable model, though. The Q5 definitely had some teething issues but seems to have improved. No lemons reported in True Delta's survey. I wouldn't recommend a first model year Audi though, and I just wouldn't recommend a VW, period. 3 series BMWs seem to be holding up about as well as the A4, I guess they've finally dealt with all of those fuel pumps as the difference between 328s and 335s seems to have mostly leveled off. The new 5 also seems ok, not great. The E-class was doing very well for awhile, but it seems not anymore. The old adage of German luxury cars being better to rent than own still seems largely true. Lexus' sterling reputation is not what it once was. The GS350 AWD was the first Lexus to lose a CR recommendation over poor reliability. The last ES also launched with transmission problems. Lexus is probably still better than any of their competition overall, but the days when you could nail the hood shut and drive it forever are over.
Heard some bad/disturbing things from a Audi/VW tech a few days ago. R8 Engine failures and swaps after 200 miles. Bent aluminum frames from hitting potholes. Horrid QC from the factory shipping cars w/ only one half side of a car functional. On and on.....
