First issue was front suspension coils. Replaced both. Biggest issue was once the weather became very cold, car would not start. Ended up being a victim of the bad intake valves provided by gm. Now, after a complete valve job and having the car run great from March 2017 to Dec 2017. . It appears it may have a cracked block. Car never overheated. Fluids were always maintained. Looked into that and apparently there were some casting issues as well. Thanks gm.
