This was an emergency purchase (with Buick Rendevous trade-in...another GM horror story) for 2008 family summer trips. DVD system a plus with four kids; averaged 26 MPG highway driving...very comfortable seats. Lack of seating flexibility (no fold-down 3rd row seats, and 2nd row seats don't slide forward) a major minus. Removing 2nd/3rd row seats is hernia territory. Repairs in 18 months ownership: (1) replaced front stabilizer links ($270); (2) reprogram PCM to address extended crank time, Bulletin #05-06-04-076B ($90). Still fighting Dealer on the flickering headlamps & interior lights, Bulletin #05-06-03-003C, that may require either replacement voltage regulator or alternator (ouch)
Hands-down: the front seats (quality leather and very comfortable) and the DVD system with wireless headsets (did I mention 4 kids earlier?). Was surprised with highway fuel economy in 25 and 26 MPG range on 1000+ mile trips, and have even averaged in low 20's around Tampa (city driving).
Can GM build a 100K mile vehicle? Well documented electrical problems appear fixable...concerned about engine/transmission/suspension long term reliability. Our 2002 Buick Rendevous traded-in for this Terraza blew-up at 60K; first vehicle I've owned that did not reach 100K miles. Can GM compete??
