I checked the other board this brake booster problem was very common on the 07's, I read a post by Small Dealer about it, many cars had it before hitting 1000 miles. Mine has 37,000. Most of the problems I have had a very common, fuel rail and pump VERY common, my thermostat was not bad, they just replaced it to fix a problem they installed, air in the system, took me telling them what to do to get that one fixed on the third try. It was installed when the radiator temp sensor that feeds the ECM went bad, this one is not so common. I had a cam sensor go bad, also very common, Chuckdoc had same problem, the top was replaced, we all know that story. So most of the problems I have had a normal Solstice problems, most of these were fixed on the 08's and 09's. So all in all I have had one unusual problem, the rest were almost expected. That would be why I bought the extended warranty. I also live about a mile from the dealer and everything they do is free so why not take it in for every little thing. They take good care of me and never give me a hard time about the mods so why not.
