Vehicle shakes when driving, especially on highway, sluggish to accelerate, making highway driving fearful. Vehicle also is rough at idle, with possible dying of engine at stop lights. 8 repairs since July, 2017 - all relative to same issue - camshaft/exhaust. This current repairs has been for the balancing shaft/water pump chain, tensioner and gaskets, seals, etc. I have done a timeline of issues/repairs to try to take on gm. Good luck I realize. From the 7 dealership trips in the last year they appear to all have been related to the initial damage to the exhaust/camshaft repairs as each and every time since then, either the exhaust of the camshaft has been repaired in one way or another. The initial issue was sluggish acceleration, engine light on. Repaired exhaust and intake camshaft actuators. Then the alternator/belt went out (not counted in the 7 - had repaired elsewhere). I didn't know they failed from oil all over them until they started to fail again and looked under hood and saw oil all over the thing. Took to dealership where they replaced r+r seal, pulley, belt and balancer. Since then we have had the balancer 2x, timing chain 3x, tensioner 3x.
