During the mornings when first starting my truck, I get a stutter or hesitation to the engine when accelerating out of my driveway. This happens just about every morning. I have determined that the truck has to be off for about 10+ hours. The stutter/hesitation goes away after the car warms up in about 1 mile. Have had the truck into the shop but they can find NO problems.

Our 2018 Chevrolet Silverado 1500 was purchased new and only serviced at Chevrolet dealerships. While on vacation we were driving on a 3-lane paved road and then engine started knocking for a few seconds and then a chime could be heard and the check engine light came on. The vehicle lost power and the vehicle was difficult to control. We were fortunate that other vehicles were able to avoid us since our truck slowed quickly (without the brakes being applied). The vehicle had to be towed to a local Chevrolet dealer for diagnostics. The dealer found that the hydraulic lifters on the right bank of the engine collapsed (resulting in a misfire) and there was extensive engine damage. The vehicle was equipped with a 5.3l engine with AFM/DFM (cylinder deactivation). Mileage was 64,562. Vehicle was repaired with "upgraded" valve train parts from General Motors as this failure mode seems to be somewhat common in AFM/DFM engines (can find class action information during web search).

I have a 2018 Chevy Silverado 1500 that I bought in June of 2018, brand new from integrity Chevy in Chattanooga tn.. One ago ago I was driving home and the check engine light came in and starting running poorly and you could hear a knocking noise coming from the engine. I took it back to integrity Chevrolet in Chattanooga, the employee at the auto service counter got inside and started the truck and he new at once what the issue was, he didn-??t even take it back to the shop so the mechanic could look at it. He told me it was the lifters knocking. I left the truck with them. The next day he called me and told that the lifters where bad and had bent push rods. They had to replace everything on both sides, told me how much it would cost. It was out of warranty as I had 74,000 miles on it. The total cost that I had to pay was $5,468 dollars. The truck is less then 4 years old. The employee at the desk when I paid for it said that I just paid for a new engine! Again the truck was less then 4 years old.

Driving on highway 70 mph with out prior warning the truck begins to shake, backfire, lunging, loss of power, all the lights on the dash starting going crazy, cars behind me trying to avoid hitting me, it wouldn't speed up, having a hard time getting it off the road and out of the way of highway traffic before getting rear ended by traffic behind me. The truck only has a little over 60000 miles on it which is just beyond the 60000 mile warranty, The truck lost compression because of a lifter failure in the motor. After this I have no interest in ever buying another Chevy product, If they cant build a motor that will last more than 3 years maybe they should rethink their future in the auto industry.

Twice now GM has recalled the block heater for my truck. The first remedy did not fix the issue and had to be recalled again. This was back in July 2021. It is now the end of November 2021 and nothing more has been done. My truck requires a block heater in order to start in the upcoming cold months. This will make two years in a row I cannot use my truck when the temperatures fall below freezing. It directly affects my livelihood because I need a truck for work. What more can I do to speed this process up" How is it GM can still sell new diesel pickups with working block heaters, but are not required to fix the older diesel pickups"

The engine gave out at 60k miles. Only covered buy the extended warranty I bought. the transmission thunks on downshifts. The exhaust adaptive valve started making a terrible noise at 40k miles. I took it to the dealership for them to tell me my extended warranty doesn't cover it and to buy an aftermarket exhaust because it would be too expensive to replace it. I think they quoted me at $1200
