Did you get the actual GM part or the Dorman part? I was told the original part was being redesigned and wouldn't be available till August! I have been waiting since October!I have a 2014 2.5 Malibu and have been watching this for weeks. After some rough idle and odds sounds for a few days my car had the light come on. I took it in and they diagnosed this part as failed. However, they had no part. I have a couple other cars so shifted to driving those while waiting. FINALLY after a nearly month long wait my chevy dealer got in a box of 12 and called me. I had the part installed today for 350. After driving about an hour everything is fine. Another guy was sitting right by me in the waiting area and had a 2015 in getting the same part he had been waiting 6 weeks! I'm glad they finally fixed this part shortage.
