While driving my vehicle, with around 85,000 miles, the engine suddenly began running rough and felt jerky and sluggish. This was concerning and potentially dangerous situation, as the engine failure happened while I was travelling at high speed. A sudden loss of power on the highway put me and other drivers at serious risk. The check engine light came on, so I pulled over as soon as I could safely do so. Shortly after, the light started flashing, so I shut off the engine and contacted the dealership service department. They advised having the vehicle towed in for inspection. Prior to this event, I had not had any issues with the vehicle nor had the check engine light come on. After looking into it, the dealership initially suspected a thrown rod but said they wouldn't know the full extent of the issue until they could tear down the engine. Upon further inspection, they determined that the lifters had failed and would need to be replaced. The dealership has performed all regular maintenance and oil changes on my vehicle. When I asked what could have caused this, they explained that it's a known issue with these lifters and engines - one that Chevrolet has experienced for years, even in models prior to my 2017.

Lost power to engine while on interstate.

- Moneta, VA, USA

Electronics for hands free stopped working. This part was already replaced once. When backing up, the whole truck shut down. I restarted, it said to roll drivers side window down and up. Truck started up again. Few days later... returning from trip, lost power, windshield wipers came on, electronics in truck started blinking. Pulled over, rolled driver's side window up and down. started back on road. This has happened numerous times. Whenever I gave it extra gas, asking for power to pass, same thing mentioned above happened. Very stressful! Next day, hit a hole, truck totally shut down again. Husband was able to safely coast off road, however, if he had been pulling out at a major intersection, this could have been bad. Warning light that comes with shutdown says "stabltrack issue". I have not seen our dealer service department yet, but plan to very soon. VERY unsafe... and I love this truck!!!!

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.

Lifters caused engine failure at 114000 miles resulting in needing a new engine

- Bailey, CO, USA

After remotely starting my truck, I was met with a strange noise that was both noticeable and unprecedented. The certified Chevy dealership provided three different estimates for tearing down the engine to verify the faulty lifter. Unfortunately, the dealer and warranty provider are unwilling to accept that these issues are inherent to the AFM system. Given the vehicle's relatively low mileage of 89,000 miles, such repairs seem premature.

The contact owns a 2017 Chevrolet Silverado 1500. The contact stated while driving approximately 65 MPH, the engine started misfiring and the vehicle was shuddering. The check engine warning light was illuminated. The contact pulled over to the side of the road. The vehicle was taken to the dealer, where it was diagnosed with cylinder #4 lifter failure and a bent push rod. The vehicle was repaired; however, the failure recurred while driving. The vehicle was taken to a Toyota dealer, where it was diagnosed with a bent push rod. The vehicle was then taken to Spradley Chevrolet (2146 U S 50, Pueblo, CO 81008), where it was diagnosed with cylinder #4 lifter failure and a bent push rod. The vehicle was not repaired due to the cost. The manufacturer was notified of the failure and offered to partially cover the repair. The failure mileage was approximately 60,000.

The steraring wheel shutters, after a few transmission flushes, it went away but still kicks hard when going through gears. The lifters failed in my vehicle 2 times, rods were bent.

- Mount Prospect, IL, USA

My truck is a 2017, but only has 46,000 miles on it. The engine light came on and it started banding loudly. I lost power and it would not go over 30 miles per hour. The dealer informed me the lifter failed and destroyed the cam shaft. Upon research, I have discovered this is a problem for many of the 5.3 engines. Many people are stuck now. I realize I have no warrantee, but I take excellent care of the truck and it only has 46,000 miles on it. It should not need a new motor, especially if it is due to a defect from GM. They knew about this issue and are doing nothing. I am now faced with an $11,000 quote for a new engine. This is wrong on so many levels.

- Wind Gap, PA, USA

Engine push rod was bent which caused lifters and 1cam shaft to be destroyed. Vehicle is tore down at dealership right now. The immediate decrease of speed and power while in traffic. Then a loud bang and engine missing. Yes, dealership. No No, but once it failed check engine light was flashing, anti lock brake lights came on. In the last few weeks four other trucks, besides ours, have been into the same dealership with similar problems. At the time when our truckcame in another truck was in for similar problems. The years of the vehicles are from 2017, 2018, 2019, Chevy Silverado 5.3 liter engines.

- Tenstrike , MN, USA

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.

Engine failure in December, 2024. Lifters, Cam Shaft and Cam Bearings. Working with my dealer now for an engine replacement.

- Hot Springs National Park, AR, USA

I spent 40k cash for my 2017 high country to find out GM great idea of AFM and no good 10 speed transmission/torque converter was made with low quality and careless parts. I'm definitely getting me a lawyer to fix this [XXX] because all I've ever wanted was this body style but all they care about is money over quality. GM and they're retail sellers knew about AFW problems and sold us [XXX] anyway. They are saying that transmission issues aren't they're fault and actually getting away with that answer. Who's else fault could it be when it's the same problem with the same model. To be an American and get [XXX] by our own is getting old. If I can get sold [XXX] I can at least get a shovel with it...so I'm getting a damn good shovel/lawyer. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
