Does anyone having the Enclave 08 Camshaft problem know what the build date on their car is? We are having that problem, 36 days in the shop, were encouraged when we read they were coming back running great, got it back and it runs HORRIBLE, clanky, sluggish, power steering noise, not to mention the dent on the passenger door! We're hoping to get a new Enclave, we do love the car, but are hoping to avoid the same problem. We'd like to know what the "build dates" are of cars having this problem in order to avoid it all together. Thanks in advance for your help!
