ENGINE

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.

ENGINE

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 NHTSA review whether similar engine/lifter/DFM and related powertrain failures represent a broader safety defect and whether an investigation or recall is warranted.

ENGINE

The contact owns a 2019 Chevrolet Silverado 1500. The contact stated that while driving approximately 45 MPH and attempting to accelerate to 55 MPH, the engine started choking, and the vehicle lunged back and forth, and slowly lost drive power. The vehicle was driven to a local certified mechanic while driving at slower speeds. The certified mechanic diagnosed the vehicle and determined that the Active Fuel Management (AFM) and Dynamic Fuel Management (DFM) systems had failed and caused the engine failure. The vehicle was not repaired. The mechanic informed the contact that Chevrolet vehicles with similar engines were known for engine failure. The manufacturer was not informed of the issue. The failure mileage was approximately 119,000.

At 70,000 miles the engine failed. Dealership said it was due to the current issues with the 6.2 motors but mine was not included in the recall but was being evaluated to be part of the recall so I did have to buy a new engine.

ENGINE

I was driving the vehicle and suddenly there was a loss of power and a ticking noise. I was up to date with my oil changes per dealer recommendations. Had the vehicle towed to to Chevy dealer and they said they weren’t able to find what the problem is without further diagnosing. Further diagnosing was estimated to be about $2500. I had it towed to an independent shop, Viking Motorsports, to which the owner/mechanic tore down the engine and deemed it as bearing failure in my 6.2 L87. There was no warning whatsoever, just went from running to engine dead immediately. I proceeded to an engine change that has costed me approximately $15,000 and would like full reimbursement if not partial reimbursement from GM given that this is a known issue for the problem. I did not go with the Chevy Dealership for the job since they quoted me $20,000+ for the engine swap and realistically that wouldn’t make financial sense. I have a High Country and at 102,000 miles when the engine has failed. This has put me in such a financial bind.

Wife was driving on the interstate when the vehicle revved up and then a loss of power. had to drive home while vehicle was popping and still loss of power. I took to an Independent Service Center, and they started a tune up with changing plugs. They checked vehicle and advised that it was possibly a lifter failure, but they couldn't fix it. I took to another independent service person and after a diagnostic check and looking into the engine it was confirmed it was a lifter issue. Vehicle has been in the shop for 3 weeks waiting on parts.

ENGINE

I have a 2019 Chevy high country that went into engine failure when going down the freeway to work. The engine light came on flashing and the engine was stuttering. I had it taken into the local Dealership where they first replaced catalytic converter. 3 months later I had engine failure again going down the freeway. I had them drop a whole new engine into it. I understand there is an investigation regarding a recall for 2019-2020 year vehicles. How I got the vehicle: I had previously bought a certified used Chevy Silverado 2016. It also had engine failure where it would shut off in the middle of driving. I repeatedly took it back to the dealership (different dealership) and they could not fix it; Instead had me test out another loaner vehicle for possible purchase. Driving off of the lot that loaner vehicle engine light came on. I took it back and they failed to mention to me that they dropped a new block into that one. After that I got another loaner vehicle that I was pigeonholed into purchasing as they could not figure out the issue with my previous purchase. 6 months later it started having electrical problems with rear cameras not working, sensors out, etc; Then eventually the engine failed. The amount of money I have spent and growing safety concerns I have for transporting my family and myself are beginning to grow. I do not want to incur subsequent mechanical failures/expenses in other areas due to previous engine failure.

ENGINE

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!

At 60k miles we had a lifter failure that caused an engine replacement. We were traveling home on I-10 about an hour from the Texas Border. My wife was driving about 70-75mph. We had to loud pops and the truck started shaking badly. The pickup was purchased in May 2021 with 26,450 miles. It has been well maintained, so the lifter failure was a complete surprise. We booked a room at a local hotel (3 nights total). The towing company took it to the local Chevrolet Dealership. The dealership couldn't even look at it for over a week. My brother in-law drove 6 hours from our home with a trailer and we hauled it home. We scheduled an appointment with our purchasing dealership and dropped it off. It took a week to get the diagnoses. It was a lifter failure. Our warranty company authorized an engine replacement, but the dealership wanted to just do a cam shaft and lifter. We were without our truck for over a month. It then cost us $300 plus for componets not covered.

ENGINE

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.

2019 Silverado experienced sudden engine failure while driving, creating a safety hazard. Had taken vehicle to Serpentine in Tallmadge Ohio for brake repair as well as a ticking sound a couple of times within the past 2 years. Each time the complaint regarding the noise it made was not addressed or documented as they said it was the brakes. While driving the truck, it started clanking and banging, smoking and spewed oil all over engine and ground. The truck is completely inoperable.

On Sunday, April 12, 2026, at approximately 5:00 PM, I experienced a sudden and complete engine failure while driving my 2019 Chevy Silverado equipped with the 6.2L V8 engine. Without warning, the vehicle lost all ability to accelerate, creating an immediate and dangerous situation for myself, my family, and surrounding drivers. I was forced to rely on the vehicle’s remaining momentum to maneuver to the side of the road, all while other drivers honked as I attempted to merge with no engine power. This incident caused significant stress and posed a serious safety risk. My vehicle had to be towed home and then to [XXX] Casa Chevrolet at [XXX] . After inspection, the dealership informed me that the engine requires a full rebuild, despite the vehicle having only 115,697 miles. According to the dealership, the engine shows **no compression on all cylinders**, **crankshaft and camshaft compression failure**, **pistons coated in oil and fuel with visible damage**, and a **non‑functioning timing chain likely due to a broken guide**. These findings mirror the exact symptoms currently under investigation in GM’s **EA25007** inquiry involving the 6.2L V8 (L87) engines in 2021–2025 GM trucks and SUVs GM has already issued a major recall affecting nearly **600,000 vehicles** due to defective connecting rods and crankshafts that can cause sudden engine failure, stalling, and potential fire hazards. Although my 2019 Silverado is not included in the recall, it is experiencing the same catastrophic engine failure associated with the defective components identified in the investigation. The dealership has quoted me $10,000 for an engine rebuild and has refused to assist with the cost. I have also filed a complaint directly with GM, as this failure presents the same safety risks and mechanical defects acknowledged in the recalled models.
