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.

- Wake Forest , NC, USA

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.

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.

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)

2 times total electrical and engine failure while driving.

- Paducah, KY, USA

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

- Garner, NC, USA

Engine shuts down on its own causing steering wheel to jerk and almost locks preventing control. Has been doing this for three weeks and is now getting much worse. Seems to do when making slow speed sharp turn. Almost hit another car in intersection yesterday due to steering control loss. I have seen numerous mentions of this on the internet but seems GM does not have a fix. The truck is now dangerous to drive as it can completely shut down in the middle of an intersection.

While turning vehicle at slow speeds the trailer warning, no trailer on vehicle, stability control hill assist radio and steering stop working as well as vehicle will stall out. Depending on when it happens it may stall while turning into traffic. I have searched the issue and found there is a ground problem under dash near windshield. It has happened multiple times like 15 as of this date.

- Danville, IL, USA

In reverse my brakes dont work, its like they are grinding, ive changed the rear brakes hoping to fix the issue, i have no codes. It has almost made me wreck due to failure to stop with my kids in the truck, also the afm system is defective in order to keep my engine as safe as possible i had to put a afm deactivate plug into the obd port. Ive tried to figure out the brakes but no one can explain. Spending 34 thousand dollars i expect to have my vehicle safe for my children. I have been strictly chevy my whole life but this is unacceptable. Where we live in alaska id expect the vehicle to be in order and it does it mainly at steep hills and it hasnt done it when ive had people look at it.

Torque Converter

- Princeton, KY, USA

Torque converter clutch system stuck in -??off-??; and won-??t engage when commanded by system-??this is apparently a known and common issue. Causing gears to not engage properly and a safety hazard when driving on freeway and higher speeds.

- Dublin, CA, USA

Complete loss of electrical system power and engine power, vehicle stalls and Coast to a stop. This has happened seven different times in the last 4000 miles driven. Possibly due to faulty ground connection electric power steering system and or stabilitrak I don't know but it is very dangerous. And there has been many other people experiencing this on Silverado Facebook groups.
