I dont undertand why there isnt a recall on all these motors! 180 thousand miles 2nd owner and motor blew. (First owner was elder couple) Known and common problem from timing chain. Recall put out for 2009 but 2010 not covered! I still owe 10 grand!! Just recently spoke to another 09 enclave owner 120 thousand miles stretched timing chain. And another owner of 09 Acadia motor blown because of timing chain they both owe more than 3 grand! And no one wants to do the work! Even if you have the money for the repairs! Buick do something about this. Not No extended warranty thats just crap! Throw out some recalls an make customers happy. If not y'all better do something before you create more unhappy customers. I see bankrupt happening in your near future!
