According to GM, Aveos should have their timing belts replaced at 60,000 miles - mine broke at 55,000. Apparently this is a huge issue with 2004-2007 models (see http://aveosfail.com/). Anyone else have this expensive problem? (I'm up to $2,000 in damages - all 16 valves were broken, the timing belt of course had to be replaced, plus a few other parts; I was quoted $3,500 by the dealership, and they hadn't even noticed all 16 valves were broken!)
