2017 Chevrolet Silverado Engine Problems

The vehicle has experienced persistent engine performance issues that have not been resolved through standard repairs. Initial diagnostics indicated knock sensor faults, which were replaced at significant cost. However, the issue persisted and additional codes related to air fuel imbalance (P219B) appeared. The vehicle continues to exhibit reduced power, hesitation, and inconsistent acceleration while driving. This creates a safety concern, particularly when merging into traffic or attempting to accelerate in situations requiring reliable engine response. The dealership has quoted a minimum repair cost exceeding $7,000, with the possibility of increasing to $10,000 depending on further findings once the engine is opened. Due to the high cost and uncertainty of repair, the vehicle may remain in operation with an unresolved defect. Research indicates that similar issues have been reported by other owners of this vehicle generation, suggesting a potential broader defect that may impact vehicle safety. This issue affects the vehicle’s ability to deliver consistent power and safe acceleration. Given the relatively low mileage and the severity of the repair required, this may represent a defect that warrants further investigation.

My truck only has 72,000 miles on it, yet the lifters in the engine are failing/ malfunctioning. While in drive, it has a hard time shifting into higher gears causing the engine to continue revving but not picking up more speed. A quick google search shows this to be a common issue. GM was made aware of the problem but did not offer much help in resolving the matter. GM specifically stated the NHTSA needs to say it is a safety issue before they will do anything about it.

I was driving in the rain 3 nights ago when my Chevy Silverado unexpectedly started shaking very bad , jerking while trying to brake, surging forward and total loss of acceleration. My dash lights were blinking and I was scared ,I had no idea what was going on. Since our family are loyal Jba customers( we own 2 silverados) and payed for the extended warranty and certified warranty I drove straight there and explained what happened. I was scared and crying, just diagnosed with Vulva Cancer stage lllC. Well the truck has been in the shop at jba diagnosed with bad Cam shift rod and lifts. They want $10,300.00 for repair. Even though we've been with them so long and had every maintenance done through them they weren't helpful in helping. Can someone help me? I need to be able to get to John's Hopkins for my cancer treatments. I've looked up this issue and it looks VERY common. Please, help me. Jba had me sign a document so the dates can be verified.

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.

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.

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.

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

Truck started making a solid bass thumping as driving then got worser as days went by, then I spent money at 4 places to get opinions but no1 wasn't definitely, so I had the engine opened up and there it was a SPLIT CRANKSHAFT, I knew it was something there bcas I pull oiled and I seen metal themes/ grit in my oil, And there's no recall on my truck, then I did research online and yesss it's alot of issues like that, plus DOD is defeated on those chevys, so I need a whole other motor

making a ticking noise on the engine

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 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.

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.

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

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

The contact owns a 2017 Chevrolet Silverado 1500. The contact stated that while her husband was driving at 70 MPH, the engine had a misfire, and the vehicle started shaking. The check engine warning light was illuminated. The vehicle was parked at the workplace and a handheld scan tool retrieved DTC: P0300 and P0324. The vehicle was towed to the residence and then was towed to a dealer to be diagnosed. The contact was informed that the lifters and camshaft needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was unknown.

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
