I own a 05 Terraza and have had numerous problems. From the mysterious starter problem GM can’t seem to duplicate to a transmission slip and many other small things. The big one is the tire wear after 4000k, the outside of tires were almost bald and of course GM explained it as low tire pressure so over the next 10,000 miles I had a tire rod, sway bar and barrings replaced, a front end alignment lots or tire rotations and balancing. After all this GM did replace the tires, but I did not want the Goodyears back on the van and paid the difference to upgrade to Michelins. I now have 21000 on the new tires which are considered 80,000 mile tires and they are almost bald and will need replacing within the month. The dealer assures me this is a COMMON CHARACTERISTIC of these GM vans and every Terraza, Uplander etc. owner is experiencing this same wear but the average Soccer mom just doesn’t notice the tire wear. As an educated professional woman I was offended by that comment!! Now since I did not put Good years back on the van GM puts the blame on the tire maker for the same wear I had with the Goodyears. IS anyone experiencing unusual wear with their tires???
