Filed Sep 23, 2026 · Engine · FL

vehicle has been to the dealership many times for issues with the engine and burning oil, we have brought it in to chevy wallace dealer for all this and have paperwork for all this, however torque convertor has been replaced 2x in one year due to faulty parts. the dealeership finally told us that the afm lifters cause the engine to go and needed a engine replacement. my wife has been so upset over this matter because she loved the truck. all this has been inspected by dealer so many times and we kept geting the run around. we had multiple check engine lights and misfire codes. then the last straw was when the engine had a horrible knocking noise which we have on video.now that she traded the truck in because dealer said it was not covered under warranty because it lapsed by 1 month we had to get a different vheicle due to knowbody helping us and now were screwed with a insane payment. we have been dealing with this for a few years and no help from chevy even with a extended warranty that covered it all. i am not asking for the world but chevy has to be responible for something. my wife really needs help with this we lost a damn nice truck and want some kind of compinsation for it

I was driving my 2019 Chevy Silverado TrailBoss with 81,000 miles at 65MPH on I-80 East in Omaha, NE, when 3 warning lights came on. The first was the Service Parking Brake. The second was Service ESC. The final was a flashing Check Engine light. My truck started backfiring/misfiring, making a loud ticking noise, and running extremely rough. I was trying to merge off the interstate, but it was running so rough that it made it very difficult to do so safely. Eventually, I just had to finish going where I was headed and park it in the lot. I did some research and called my local shop. They said to stop driving immediately and have it towed to them for inspection. They used a diagnostic tool and diagnosed the issue as a DFM lifter failure. But they could not fix it there and recommended I take it to a different shop. I had it towed again, and they did their own diagnostics and have the same idea, but without taking the engine completely apart, they can't tell for sure. They want to charge me $1,250.00 to inspect it further. I called the dealer where I purchased the truck back in 2019 and am working with them on next steps. The last shop quoted me $7,800 repair if it is indeed the DFM lifters. Based on what I know, this is a known issue with these trucks. GM has an "Out of Warranty Policy Assistance" in place just for these know lifter issues. This is very concerning that GM hasn't done a recall on these parts as it has shown to be a safety issue when driving the vehicle in traffic on the interstate. I just hope that GM assists me with the repair costs because it is not guaranteed and I cannot afford $7,800 right now.

I am reporting a potential safety defect involving my 2019 Chevrolet Silverado 1500 Z71 Trail Boss (VIN [XXX]), currently at approximately 63,000 miles. My truck suddenly developed a rough idle, engine ticking, and a cylinder 3 misfire. The check engine, traction control, parking brake, and “Service ESC” warnings appeared. The transmission also began shifting extremely hard, at times feeling as though another vehicle had struck the truck from behind. The oil pressure gauge also stopped functioning. Due to these symptoms, I stopped driving the vehicle. A diagnostic scan produced P0303, P0449, P0498, P0499 and P0500. After replacing a failed cylinder 3 spark plug, the truck initially ran perfectly for approximately 20 minutes before the rough idle and warning lights returned. The vehicle was subsequently diagnosed by a Chevrolet dealership. The dealership determined that the engine suffered a collapsed lifter that damaged the camshaft and other internal engine components. The engine repair estimate is approximately $10,000–$12,000. The dealership has also reported that the transmission is slipping and believes the torque converter/transmission requires approximately another $6,300 in repairs. I am concerned that a lifter/DFM-related failure causing a misfire, rough running and potential loss of engine power could occur while a vehicle is traveling at highway speed and create a significant safety hazard. The severe transmission shifting and subsequent slipping are also concerning because unexpected vehicle behavior during acceleration or while in traffic could increase the risk of a crash. The truck has been regularly maintained and has relatively low mileage for its age. I am requesting that the federal safety agency review whether similar engine/lifter/DFM and related powertrain failures represent a broader safety defect and whether an investigation or recall is warranted.

I was camping at a state park outside of Kenton Ohio. On Sunday July 19 2026 while backing up my travel trailer I lost power steering to my 2019 Silverado 1500. then a message came on my display saying service power steering soon and then a check wiring harness warning. I turned off truck and restarted it and warnings cleared and power steering came back. The following morning July 20th started the truck, no power steering and service engine light was on drove to Kenton and had codes read. Had multiple codes for different control modules. Power steering came back and I was able to drive home. Called my dealer and was able to get appointment on July 24. Tried to start truck and it would crank, start run rough for a few seconds then stall out. Had to have it towed to dealer for repair. End result faulty ground strap from body to frame, loss of electric power steering ability while driving due to a ground cable could have been a very dangerous situation for everyone in the vehicle and on the road

While driving, my 2019 Chevrolet Silverado 1500 with the 5.3L V8 suddenly lost engine power approximately a quarter mile from my home. The vehicle has only 35,000 miles. A check engine light indicated a misfire, and I confirmed cylinder 7 was misfiring. I replaced the spark plug, plug wire, and coil pack, but the misfire continued. The dealership diagnosed a failed lifter in the Active Fuel Management (AFM) system and is disassembling the engine to assess further damage. This matches the widely documented AFM lifter failure pattern in GM 5.3L V8 engines. The sudden loss of motive power while driving created a safety hazard. All maintenance was performed at GM dealerships.

Purchased 2019 Chevrolet Silverado High Country Edition with the 6.2L engine and 143K miles for my son. The vehicle had a clean service history on Car Fax. On the day we purchased the vehicle, we drove it home and noticed it was shuttering at times. I used my computer scanner and it came back with a misfire cylinder #5. I troubleshot the issues and noted that the most common thing was a spark plug. Therefore, I replaced the spark plug and it drove much better. Two weeks later, my son was driving vehicle on I-40 near Nashville TN and without warning, vehicle stalled, locking steering wheel in place! Check engine lights came on and instructed him to place in neutral and restart, which he promptly did. The vehicle started, but went in limp mode making loud noises in engine before shutting off again. Luckily, traffic was minimal at 8 pm and he was able to get it over to the shoulder and avoid any injuries or accident. Towed it to Nick Mayer Chevrolet in Dickson, TN where they diagnosed it with catastrophic engine failure and needed to be completely replaced. This is the same issue that GM is being sued for and have somehow managed to take the stance that the lifter/cam/DFM issue only existed in 2020-newer models. The 2019 is when they changed to the newer body style and the new Gen V L87 engine in the 6.2. Despite the clean vehicle history, dealership reached out to GM and they stated they would not help cover any repairs but would gladly take 14K to fix it. The 2019-2026 models all need to be recalled due to this safety issue and fixed before catastrophic engine failure claims another victim financially or worse!

The engine in my truck failed while driving down the interstate highway (I-10) on May 28, 2026. At the time of failure, a loud popping noise emitted from the engine. Power and speed were reduced as the result of the failure. The Check Engine Light and Service Engine lights illuminated as quickly as the failure occurred. As many vehicles were simultaneously traveling along the highway at speed, my vehicle suddenly slowing down without indication (brake lights) could have inadvertently caused an accident. As a result, I continued driving the vehicle under reduced power to my home which was only approximately 2 miles away. During the 2-mile drive to my home, the loud popping noise intermitted but reduced power was consistent. Diagnostic checks revealed a code P0305 indicating that cylinder #5 was misfiring. Checking the components of that cylinder revealed the intake valve of cylinder #5 was not actuating when the engine was running indicating a failed lifter & camshaft.

I own a 2019 Chevrolet Silverado with approximately 84,000 miles. Prior to the engine failure, I noticed abnormal engine ticking noise, especially during cold starts. I reported this concern to the dealership during a service visit. The technician verified the engine noise but stated that the noise was normal and no repairs were performed. Over time the condition worsened and the vehicle began experiencing engine misfires and internal engine damage. Diagnostic inspection later revealed oil contamination and cylinder wall scoring requiring full engine replacement. Additionally, while driving on a public street, the serpentine belt suddenly came off the engine without warning. This created an immediate safety concern because the belt powers critical systems such as power steering and engine cooling. Losing these systems while driving could cause loss of vehicle control. At the time of the incident, my children were in the vehicle and there were pedestrians and other drivers on the road. The sudden mechanical failure created a dangerous situation that could have resulted in a crash or injury. No warning lights or messages appeared on the dashboard prior to the engine failure, and the check engine light never illuminated. Because the engine concern had previously been reported and dismissed as normal, the problem continued to worsen until catastrophic engine damage occurred. I am submitting this complaint because I am concerned that this may not be an isolated issue and that similar engine failures could pose a safety risk to other drivers.

I am reporting a catastrophic internal engine failure in a 2019 Chevrolet Silverado 1500 at 87,600 miles. Prior to this event, there were NO warning lights or symptoms. While traveling alone during the holiday on a remote, one-lane road with no shoulder, the vehicle suddenly suffered a loss of power. Every warning light on the dashboard illuminated at once, followed by shaking, misfiring, and loud knocking from the engine. Because I was on a one-lane road with no place to pull over, this created an immediate safety hazard for me and oncoming traffic. I had the car towed to the dealership ( where I bought the truck) confirmed the failure was a collapsed lifter and scored camshaft (which i found out to be a known design flaw in the 5.3L DFM engine). The dealer said it was not under warranty. I felt held over a barrel by the dealership; they initially provided an inflated quote and told me it would cost approximately $1,200, not including tax and shop fees, just to put the engine back together if I wanted to tow it elsewhere for a second opinion. I was forced to pay over $8,395 under protest just to regain use of my primary vehicle after 42 days of downtime. Upon completion, the dealer provided a "Lifetime Warranty" on the replacement parts. This is a tacit admission that these components were never intended to fail during the life of the vehicle. GM refuses to include this vehicle in its coverage list, treating a dangerous engine stall as a simple "out of warranty" repair. This is a systemic safety defect that requires a mandatory recall expansion before it results in a terrible accident. My understanding is that a Class Action lawsuit, Harrison vs. General Motors, for this same thing, but they say my car is not in it, i should have been put on notice for this so I could protect myself.
