Bought the truck brand new, after 20,000 miles started vibrating. Took it to the dealership said it was the transmission shutters. They changed the fluid. At 50,000 miles did it again, they said GM came out with a thicker fluid, but it in there. Was fine for a while. At around 135,000 miles getting the vibration again. Also, at 140,000 miles cylinder 8 misfiring. Took it in and they tore it apart and said cylinder 4 and 8 lifter failure. Damage to cam and bent rods. Had to replace all lifters, cam and rods. Cost over $10,500, but had BG warranty used that additive every oil change so BG covered $4,000. I went by the oil life indicator on the truck to determine when I needed to change it, but apparently for engine for life you have to change it more frequently at 6,000 miles, so they wouldn’t cover that part.

The AFM system is a faulty system that starved my lifters of oil and they ended up collapsing causing a flat spot on my cam. The engine code would come up as a misfire but the code is caused by the flat spot created on the cam by the lifter it's a faulty system that cost me $7,000. My 8spd transmission also has a hard shift from 1st to 2nd pushing the vehicle forward and jerking it when it shifts. The dealer and GM said this was natural with this type of transmissions which we now know is a lie.

The truck suddenly started misfiring, running rough and lost power while driving. All the dash lights illuminated and the check engine light began flashing. We were a couple hours from home so we had to have the truck towed home. This could have been much worse as we were towing a trailer on a busy highway but luckily we were able to pull over to the side of the highway. Upon returning home we had the truck checked at the local Chevrolet dealership service department and were told we needed a whole new engine. After about 5 months after the initial incident we paid to have a new engine installed at the same dealership that inspected it. The truck had not exhibited any signs of any problems prior to the incident.

experienced several years of misfire problems , replaced spark plugs twice which seemed to fix the problem short term. while out of my home state(retraining for a new job in the Airforce) the misfire became significantly worse and made the truck undrivable. brought the truck to a local mechanic and they told me that I had bad misfires on the AFM/DOD cylinders and need to replace them all. chevy confirmed the diagnosis also stated there not going to offer coverage for this know issue. this know failure has costed me 15k in total costs when GM has know about this for years and could have fixed it before costing me so much money . I've also received no help from the chevy dealership or corporate regarding this know problem and I've been told its going to be an out of pocket repair and there's noting they will dop to help.

Stalling with no power transmission is putting me at risk since I first purchased this vehicle. Transmission needs to be replaced because of the defective drive shaft on all 2017 models . Really serious problem with a hard shift and multiple misfire. Just not sure what to do at this point. I’m still paying for a truck that’s not working.
