2015 Chevrolet Silverado complete engine failure. At 143,000 miles the engine failed because of the displacement on demand fuel injection system/lifters. Lifter failed without warning, destroyed the camshaft, cam bearing and crank and crank bearings. Chevrolet/GM were no help at all and took on responsibility for building defective engines they knew would fail after the warranty expired. I ended up spending nearly $17,000 to have a remanufactured engine installed.

AFM/DFM on my 2015 Chevrolet Silverado 1500 LT had to lifters collapse without warning and no engine light was hole I had my 7 year old daughter and 10 year old son in the vehicle while I was driving. My kids got scared and I had to react quick and go into a drive way. While I was driving my vehicle gave out without warning and could-??ve caused a serious accident to my kids and myself including other vehicles.

86K miles smelled gas. Dealer replaced one fuel injector on the 6 cylinder rail. At 108K miles, catastrophic engine failure caused by misfire in the #6 cylinder. No compression or diagnostic testing done at initial fuel injector replacement. It is now my understanding that it is good practice when replacing one fuel injector, all should be replaced. After truck was inoperable at 108K miles, ran a borescope into the 6 cylinder shaft and noticed massive wash and scoring. Goodwill from GM was denied for an engine swap. Subsequent diagnostic testing revealed low pressure in all cylinder heads. I don-??t put a lot of miles on this truck per year and suspect the problem compounded over time without notice. There was gas mixture in the oil, however this issue was never brought to my attention during routine maintenance and oil changes. I know there were issues with the 6.2L and didn-??t know of parallel or residual issues with the 5.3L. Long story short, I had to go with an engine swap on a truck with relatively low mileage.

I have had a problem with the theft deterrent system which, shuts the truck down and issues a message saying "turn the driver side window down and then up". After 5 minutes the truck starts back up by itself? This has occurred sitting in Popeyes drive thru line in August 2024 in Benton Harbor, Mi. This has occurred 3 times in the past week, 09/25/25 driving on Garrett road it shut down during the entry into a "s curve" 09/26/25 driving into my drive way 09/28/25 driving into my drive way Took the truck into Wimberley Chevy dealer and they searched for error codes and checked some of the ground wires not connected properly and found the negative cable on battery was ok. I don't know if any other wire connectors were checked, however I have had this before and the dealer said they would have to keep the truck as it may take quite some time in confirming all connections were good. the service manage of LeValley Cheverolet stated that they would require a $1,000 deposit for them to start looking into the problem and again require another $1,000 deposit to continue and then another etc. I will not drive my truck on any major highway or in any very busy large city for fear of having a return of another shutdown and no place to pull into as I was only coasting when I entered the "S curves" and had space.

The contact owns a 2015 Chevrolet Silverado 1500. The contact stated that while driving at various speeds, the engine started shuddering and the vehicle decelerated unintendedly. Additionally, the check engine and traction control warning lights were illuminated. The vehicle was taken to the local dealer, who diagnosed the vehicle with engine failure. The contact was informed that the engine needed to be replaced. The engine was replaced, but the failure reoccurred. The contact was informed that the engine shudder was due to a faulty fuel management system, which caused the lifters to remain in the open or closed position. The manufacturer and local dealer were notified of the failure, but no assistance was offered. The failure mileage was 75,000.

2015 5.3 with afm related failure / lifter collapse still within warranty by mileage (5 yrs, 100,000 miles I think), out by years in service, was diagnosed by a GM authorized dealership by a GM Master Certified Technician and under the supervision of service manager. Issue Description On 6/18/2025, the dealership diagnosed a failure in the #7 lifter due to afm / afm related failure / lifter collapse. The vehicle-??s engine, diagnosed at approximately 58,000 miles and minimal idle hours. While the GM Master technician is confident that only one side of lifters require immediate replacement, there is a possibility of damage to the camshaft lobe, which cannot be inspected without significant additional labor. There is also a concern about potential metal contamination in the oil, which could further impact the engine-??s performance. I also have many documented repair orders indicating my concern with the transmissions performance.

Component that failed Lifter failure causing camshaft damage. I was driving my truck at the time the engine failure and loss of propulsion. The problem was later linked to lifter failure. Car started to lose power and surge forward while I was in oncoming traffic. I pulled over and had my truck towed to the Jamestown Chevy Dealership. I have had all of my services done at the certified Chevrolet dealership. Their professional diagnosis was lifter problem with camshaft damage. The vehicle was inspected by mechanics at Sierra Motors in Jamestown Ca. No prior warning to the vehicle failure. Once the truck lost propulsion and was surging the check engine light and road traction light came on.

I was driving my truck on a interstate when the torque converter broken and forced me to stop on a "No parking" area, The cars couldn't see me until I got really close to my car and almost caused an accident, the sheriff had to intervene and signal that there was a car stopped on the interstate, it wasn't the first time that it happened, it happened 5 times since I got the truck( I have it for 5 months) I already fixed it and replaced the torque converter but it's not safe to be on the side of the road every month, it need to be fixed because it can cause many accidents

My engine shakes when shifting into the V4 from the V6 and my transmission shifts hard as well as a dieseling affect when shifting from 2nd gear to 3rd gear. Rear main seal was replaced 1000 miles ago and now has to be replaced again due to the rapid shaking of the V4 cylinder deactivation(which was a terrible way to make the reliable 4.3 Lt engine unreliable)

Experienced a problem with electrical theft deterrent system and it shut the vehicle off while driving. I tried to start the vehicle and nothing happened except it said theft deterrent system. I took the key out tried starting again and it turned over immediately. The dash said theft deterrent and I clicked dismiss but the dash icon (a car with a lock light) remained on. I then drove 11 miles home. I turned on my directional proceeded to brake upon approaching my driveway. As I attempted to turn the steering wheel the vehicle completely shut off. The info system stating theft deterrent active. I lost power steering and brakes. I needed to press the brakes with great force because the vehicle was headed towards the sidewalk and a road sign. Steering was virtually unresponsive. Vehicle stopped as the tires reached the curb and approximately 1 ft from the sign. Placed vehicle in park and started it back up. Pulled into my driveway and the info system stated I need to roll the drivers window down and the up to deactivate. I have checked all battery connections are intact and tight. The battery, starter and alternator were all checked and fine. I have no idea what caused this dangerous behavior. The incident happened on MA Rt. 126 988 S. Main st Bellingham MA 02019

I bought this truck a little over a year ago. Mileage 89,392. 2 weeks later the truck started to run poorly, shaking badly, misfiring. Took it to the garage. They told me the had to replace coil packs one one side lifters and one push rod. Truck ran good for 1 year. I know this because I had just gotten it inspected. A couple days later the truck started doing the same thing. Now it-??s in the garage again. They tell me the camshaft is shot and needs replaced including all the lifters. The truck now has just over 100,000 miles on it. The repair is about $6600. GM will allow the garage to do some work under a warranty type citation and GM will pay approximately $535. For a total of about $1000. Now my concern is this truck could break down on the highway and cause an accident just like a current recall for crankshaft and or connecting rods. If there can be a recall for that there should be a recall on this issue also. The garage has informed me they have done a lot of these repairs. Some even had to come back a second time.

While driving at 55-60 mph on Saturday, [XXX], the vehicle made a distinct engine sound and lost power, but continued to run with a pronounced misfire, and a -??check engine-?? light came on. Our safety was put at risk because we were merging into high speed traffic and I had to abruptly slow and move as far out of the travel lane as possible. I had the vehicle towed to Champion Chevrolet in Reno on Wednesday October 16 for evaluation. The mileage in was 44,252. I was told that the camshaft and some lifters had failed, and I opted to have the engine replaced with a remanufactured unit at the total cost to me of $14,660. I picked the vehicle up on 10/28/2024 with 44,259 odometer miles. I have since learned on the internet that this particular -??Active Fuel Management (AFM)-?? failure is known to Chevrolet corporate office and is the subject of a class action lawsuit against Chevrolet. I have also learned that there is the possibility of repayment to affected owners in early 2025. I am submitting this letter to bring my situation to your attention so that I am included in any list of owners that may be reimbursed as a result of this known engine issue.

Vehicle shuts off when stopping. Everything goes dead. It will eventually start again, but very annoying. What happens when it shuts off going down the highway? No power steering or power brakes, that's what!
