Have had this truck for 7 years and it has 135,000 km on it. Have had no issues with it. Had 70,000 km when I bought it so I average about 9300km/year. The other day I started it to leave grocery store and felt a bad miss as I was pulling out of my stall. Rolled down window and heard the clatter. Limped it home about 1 mile and investigated further. Cylinder 6 misfire, check engine light flashing and I believe traction control light on. The flattering gave it away in my mind. I did try swapping plug, coil and wire from 6 to 4 hoping the moss would move to 4 but no luck. Also compression dropped to 120lb when cylinder 1 has over 200lbs. Called tow truck to tow to local GM dealer. Failed lifter and 1 bent pushrod. Dealer changing lifters and pushrods on 2,4,6,8 and also VLOM. Think it may be time to get rid of this truck when I pick it back up from dealer. Dealer told me they do about 2 of these repairs every month.
