2017 Chevrolet Silverado 1500 Engine

The contact owns a 2017 Chevrolet Silverado 1500. The contact stated that while driving at an undisclosed speed, there was an abnormal metal-on-metal sound coming from the engine. No warning lights were illuminated. The contact stated that on a separate occasion, the vehicle failed to accelerate as intended while depressing the accelerator pedal, and the engine sounded rough. The vehicle was taken to two different independent mechanics, who diagnosed that the Active Fuel Management (AFM) and Dynamic Fuel Management (DFM) were impacting the lifters, which impacted the camshaft, and scraped the cylinder walls, causing the engine to fail. The vehicle was not repaired. The vehicle was then towed to the dealer, who confirmed the engine failure. The vehicle was not repaired due to the cost. The vehicle was towed to the residence and no longer driven. The failure mileage was approximately 156,000.

Our 2017 High Country 1500 Chevy Silverado is garage-kept and has very low mileage (73k). But it has the Active Fuel Management (AFM) system, which just caused lifter failure, thus causing catastrophic engine damage. In research, we discovered newer models with the AFM have been recalled for this exact problem. Unfortunately, our model truck with the AFM has not been recalled, despite the fact that the problem and damage are the same.

At 54,900K miles my truck started to experience a tapping sound from the engine. I took it to a shop and was told that the Auto Fuel Management system can cause problems with the lifters. I tried to use my 200,000/10 year Warranty, but the warranty company refused because I went over 6 months on my oil change. The cost of repairs was over $6,900 and the push rods were bent, one lifter was broke off, the cam was damaged from the lifters and a piece on the timing chain was broke. Chevy knows there's a problem with the 5.3L Engine and refuses to fix it. No warning light ever came on. This problem first appeared in December of 2025 around 54,900 miles. I have since had the vehicle repaired and I kept all the parts. Chevy should recall this engine instead of letting their customers pay the repair costs for a flawed design caused by their AFM System. I was told to stop driving my vehicle because if I continued to drive it with the tapping sound it could cause the engine to blow up. I also have an After Market Warranty which would not cover the repair because Chevy issued a Technical Service Bulletin about the problem, Bulletin No.: 19-NA-219.

I bought the vehicle with 14000 miles.had oil changed at dealership ever ,5000 miles.I drive 10 miles a day.at 55000 miles the lifters are ticking like a time bomb.It makes me sick that a vehicle with no more miles than this is in this shape.Gm should stand behind there junk motors with this afm.

The lifter collapsed causing it to scar the cam shaft due to afm/dod

Nothing yet. Between doing research and general observation the DOD/AFM is a known issue for these motors. The engine will randomly loose a valve and cause the engine to shut down causing for a major Saftey concern if traveling or towing

Loud tapping sound appears to be coming from Lifters and/or camshaft lobes from cylinder 2. Preliminary diagnosis was done by independent service center. Estimated cost to repair could be as much as $10,000. Vehicle odometer reads 72,108 miles. Vehicle started this problem early November 2025.

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.

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.

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.

The contact owns a 2017 Chevrolet Silverado 1500. The contact stated that while driving 30 MPH, the vehicle failed to accelerate as intended while depressing the accelerator pedal. The contact stated that the vehicle stalled. The contact was able to coast to the side of the road. There were several unknown warning lights illuminated. The vehicle was towed to the residence. The contact had the vehicle diagnosed by a mobile mechanic. The mobile mechanic diagnosed the vehicle and determined that there was a misfire in cylinders #3 and #7. The vehicle was not repaired. The contact towed the vehicle to B2B Fleet Services where it was diagnosed and determined that the head caskets had failed and needed to be replaced. The contact stated that the lifters were replaced; however, the failure persisted. The manufacturer was not notified of the failure. The failure mileage was approximately 65,000.

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.

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.

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

Lost power to engine while on interstate.

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

Misfiring - technician told me I have to delete the AFM and replace all lifters. $10k+ repair that I can not afford

It feels like it is licking into the four wheel drive going down the road with speeds up to 30 miles it feels like it begins to jerk I have heard other owners of this vehicle type are saying a possible recall on the transmission
