2019 Chevrolet Silverado 1500 POWER TRAIN,ENGINE

Afm lifters has failed in my vehicle 3 times as of date. Being that its a costly repair this should be recalled. Information provided is the latest mileage.

"Approximately four months ago, I noticed an oil leak coming from the midsection of the engine/transmission of my 2019 Chevy Silverado LTZ with the 6.2-liter engine. At the same time, I noticed a slight knocking or rattling noise coming from, I believe, the front of the engine. Upon taking it to the dealership, they replaced the engine oil coolant lines, only to find out that the engine was still leaking oil and still making the knocking and rattling noise. They then discovering that it was the rear main seal, they have since replaced it about one week ago. Yesterday, February 6th, about 12:15 pm in the afternoon, while I was getting off the I-405 in Renton Washington and merging onto the southbound lanes of 167. I was in the left lane and I made it about a quarter mile down 167 doing about 60 to 65 miles per hour and I lost power suddenly. As I started to merge into the right lane, I noticed the engine light came on, and then the truck seemed to kick down into first gear while I was doing 50 miles per hour, which instantly slowed it down. This forced me to cross over an on-ramp lane to get to the shoulder and come to a complete stop. After that, the truck would not start at all. I then had to sit on the side of the road for three and a half hours waiting for a tow truck to take me and my truck back to the dealership, which is also the same dealership where I bought the truck back in 2019. They have not diagnosed it yet as I just dropped it off at 4 pm on 2/5/2026. My truck has approximately 155,000 miles on it.

While driving the vehicle I began to hear a ticking noise in the engine (lifter tick) and the check engine light came on. The vehicle began to lose power and started shaking. I stopped the vehicle and turned it off and restarted it and began to drive as I was not far from home. I found that the vehicle did not have full power and was not firing on all cylinders. After getting the vehicle home a diagnostic code showed cylinder 2 was not firing. The vehicle was towed to the dealership who confirmed there was a bad lifter and roller that dug into the camshaft. The sudden loss of power and shaking of the vehicle while driving is the safety concern. It seems that this is a common problem with these engines that GM is aware of and has failed to address.

Component or system failure: The engine valvetrain (camshaft and lifters) sustained severe internal damage, including camshaft scouring, confirmed during inspection and teardown by an authorized Chevrolet dealership. In addition, the rear differential was found to contain no gear oil when the fill plug was removed during inspection. The vehicle and components are currently at a Chevrolet service center and are available for inspection upon request. Safety risk: The vehicle experienced persistent drivetrain vibration and abnormal operation that worsened over time and ultimately rendered the vehicle non-operable. Internal engine damage and a rear differential without lubrication present a risk of sudden drivetrain failure, loss of propulsion, or loss of vehicle control, particularly at highway speeds. The vehicle is currently unsafe to operate. Problem confirmed: Yes. Engine damage has been confirmed by the dealership during teardown. The absence of gear oil in the rear differential was directly observed during inspection. Inspections by others: Yes. The vehicle has been inspected by an authorized Chevrolet dealership and by third-party inspectors associated with the extended drivetrain warranty administrator. Two inspections have been completed, and a third inspection has been ordered. No repairs have been completed as of this report. Warning lamps or prior symptoms: Beginning around approximately 21,000 miles (2022), the vehicle developed drivetrain vibration. The vehicle was taken to a Chevrolet dealership at that time, but the cause was not identified or corrected. No warning lamps or messages are recalled.

This truck has been very jerky when shifting. Transmission issue plus engine had valves done but still is a problem mostly jerky really bad to the point seat belt is a good thing.

The 6.2 Eco tech V8 is failing. Chevrolet new car of Lowell Massachusetts reports that motor needs to be torn down due to component failure. Also transmission is whining and will need replacement transmission shifts hard between gears and lunges forward while down shifting.

Was driving on the highway, heard loud bang followed by a violent metal-on-metal slapping or knocking sound, and a sudden loss of engine power. Came to find it was crankshaft/connecting rod issue that is common in these vehicles. Have a picture of the broken rod and am waiting the get it repaired.

The transmission failed at 100,000 miles and the engine failed at 130,000 miles. Available for inspection. Yes the dealer confirmed both failures. No warnings. Immediate failure with engine light. Barely made it home with the transmission and the engine just stopped out of nowhere due to the dynamic fuel management system and oil consumption starvation.

I was driving on the highway at a speed of around 65 miles an hour and I heard a loud noise and the truck did a hard jerk and slowed down abruptly I then had to struggle to get over to the shoulder as cars around me were moving at high speeds then I found out that it was the lifters that failed and I started doing research on this problem and it seems to be a problem that a lot of people are having with these trucks as well as transmission issues which I was having before this happened

The contact owns a 2019 Chevrolet Silverado 1500. The contact stated while driving at an undisclosed speed, the vehicle jerked. Additionally, the transmission shifted abnormally rough, and the check engine warning light was intermittently illuminated. The contact stated that the failure could have pulled the vehicle off the road. The vehicle was taken to Napoli Kia, which was a third-party dealer assigned by the warranty company to be diagnosed. The vehicle was diagnosed with transmission failure. The contact also stated that metal shavings were found in the transmission. The contact was informed that the transmission needed to be replaced. The vehicle was not repaired. The contact was informed that parts had on back order for over eight months. The manufacturer was made aware of the failure and a case was filed. The failure mileage was approximately 70,000.

The first thing that happened was the transmission, driveshaft, and rear end all blew at the same time while I was on the freeway. I had to swerve over and get out of the lane I was in and part of the driveshaft was still sitting in the road and cars were hitting it. There was no lights or anything until it happened. I got out of the passenger side of the vehicle and looked under the truck and there was a flame coming out of the rear end. I was able to extinguish it. It was inspected by delta transmission and they said that the rear end gave out first and damaged the rest. Not even 2 weeks later the second thing that happened was my engine gave out. I was driving on the freeway and the engine stalled out on me and I barely got off an exit before the truck stopped moving. I had to get it towed to a shop where they told me that the 2 rods on cylinders 1 and 7 had given out and that I needed a new engine. Again no warning lights or anything until it happened. This all happened in February of 2025.

Leaking oil cooler lines that had a customer satisfaction campaign but it’s over and now they are leaking.

Transmission is shifting and shaking and vibration funny whines when driving and hard shifts makes clunking noises when shifting or down shifting. Engine ticks very loud and loses power

Oil coolant line detached from the crimp. GM customer satisfaction program N212326940 is exactly what has happened and GM states it is not associated to my VIN so they can't (won't) do anything about it, even though the bulletin clearly indicates 2019 Silverado 1500 (new model). This occured as I was on the interstate. I pulled over as soon as the warning came up telling me to turn the vehicle off. I had to wait on the side of the interstate for several hours for a tow to a local mechanic shop. The mechanic diagnosed the issue and took photos and described the issue in writing. Prior to the incident there was no vehicle warning light that there was an issue, nor did I receive a letter warning of the issue. This catastrophic failure of the coolant line ejected oil, coating the undercarriage and passenger running board. The program bulletin states: Condition: Certain 2019 model year Chevrolet Silverado 1500 (New Model) and GMC Sierra 1500 (New Model) vehicles, may have a condition in which the engine oil cooler (EOC) lines may leak and detach from the crimp joints. Exposure to cold temperature may also aggravate this condition. If the EOC lines leak, there may be an oil leak on the ground and if the EOC lines detach while operating the vehicle, there will be an immediate decrease in oil pressure. This will coincide with a warning on the driver information center display (“Oil Pressure Low Turn Vehicle Off”), along with warning chimes. If the customer continues to operate the vehicle, a loss of propulsion is possible. Correction: Dealers are to replace the engine oil cooler lines, oil, oil filter and refill the coolant.

vehicle's cam shaft failed resulting in major engine damage and costly repairs, vehicle less than 100k miles, same issue as recent GM recall, but this was not included in recall

The contact owns a 2019 Chevrolet Silverado 1500. The contact stated that on several occasions while driving at various speeds, the vehicle lost motive power and ran sluggishly with an abnormal knocking sound coming from the engine compartment. The check engine, traction control, and two other unknown warning lights illuminated. The contact stated the “Service ESC”, engine, transmission system, and emissions notification were displayed on the Chevrolet App. The vehicle was taken to an independent mechanic where it was diagnosed and determined that the lifters had fractured and damaged the cam shaft. The contact was informed that the cam shaft and lifters needed to be replaced. The vehicle was not repaired. The contact stated that while the vehicle was parked on several occasions, the engine was idling rough. The manufacturer was notified of the failure. The failure mileage was 112,000.

I was getting on the freeway and all of a sudden a lost power and heard a loud clunking noise. I drove as fast as I could to get in a safe area. Afterwards I had my vehicle towed to my mechanic. They said engine failure and possibly transmission failure. They found metal shavings in the oil. I had changed it myself a few weeks prior. I then took it to a gm dealer. I was just outside my powertrain warranty at about 70k miles. They said the same thing. 24k to repair. I had to junk the vehicle.

When driving normal speeds to work on a county road, engine light comes on, service light comes on. There was a tapping noise and reduced power. Luckily, there was a sports field parking lot that I could pull into to get out of traffic. We had the truck towed to our house through our roadside assistance program so that we could determine what to do. If we had not been able to pull off the road as quickly as we did, we probably would have been hit by the semi that was barreling behind us. The truck had reduced power.

1. engine/transmission 2. while driving and acceleration vehicle stalls/hard shifts. The truck was running just fine one day then the next day upon starting the truck, Vehicle warnings for "service" Parking brake system and ECS started showing up and the truck started running rough, smoking exhaust, smelling, and the air conditioner went out. all at the time/day. 3. An independent service center provided a diagnosis that stated the "motor was shot" oil was getting passed the rings/seals and entering cylinder 6.

The contact owns a 2019 Chevrolet Silverado 1500. The contact stated while driving at various speeds, the vehicle jerked and vibrated while shifting into gear. The check engine warning light was illuminated. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure and informed the contact that the VIN was not included in an Extended Warranty coverage related to the failure. The failure mileage was 200.

While driving on the highway with my four year old with me the truck jerked and then triggered 3 lights on my dashboard, this made getting to a safe spot uneasy as it was jerking and sounded like it was reving up and down and overall sounded not good. Truck was towed to mechanic and was discovered the lifter failed due to the Active Fuel Management (AFM) or Dynamic Fuel Management (DFM) in that engine model. That failure caused further engine damage to the cam shaft and needs an entire rebuild of the top part of the engine. There were no other indicators that this would happen until it did. I contacted Chevy and they are aware of the situation and offered "cost assistance" only if it was brought to a GM dealership. Given the engine had to be taken apart to figure out what was wrong they said the only way to get assistance was to have the garage put it back together and then tow it there and have their mechanics look at it to determine if they could cover part of it. This isn't a viable option to me seeing how there isn't a guarantee of any assistance and would potentially cost more long term.

The contact owns a 2019 Chevrolet Silverado 1500. The contact stated while driving at various speeds and accelerating from being idle, the vehicle aggressively started jerking and the vehicle lost motive power. The contact coasted to a safe place and waited before attempting to restart the vehicle to continue driving. The vehicle occasionally restarted immediately, and other times took a long time before restarting. The contact also experienced unintended acceleration. The vehicle was shifted into neutral to decelerate. The contact stated that the failures occurred without warning. The vehicle was taken to the dealer who diagnosed that the transmission and lifters had failed. The six lifters were replaced; however, the failure persisted. The lifters were replaced a second time, but the failure recurred. The vehicle was returned to the dealer, who then diagnosed that the radiator fluid was leaking into the engine. The engine was replaced. The failure persisted, and the TCM was replaced; however, the failure persisted. The wiring harness was replaced for the second time. The failure persisted, and the vehicle was returned to the dealer; however, the vehicle was not diagnosed or repaired. The manufacturer was informed of the failure, and a case was opened. The failure mileage was 10,000.

Lifters froze up on #4 piston twice, both times going down the highway. Transmission would jerk after shifting gears, had bad torque converter shudder from 18 mph on up. Can’t pull trailer over 55mph without the whole cab vibrating like crazy

Bought my truck with 29,000 miles on it. Was making a noise in rear tire. Took it in and it was the break calilper. Dealership wanted $1500 to replace it a week after I bought it. Stated that it was not covered. After a week of arguing, they did not charge me for it. Around 40,000 miles, every once in a while, it would feel like I was being rear ended when I came to a stop. It was not often, but around 55,000 miles, was more frequent. I took it to the dealershp at 62,000 miles and they said that it was a torque converter and would not be covered. Fixed it at a shop $2700. Lifter and Cam in the UP of michigan $5000. Oil lines at 110,000 $700. Torque converter again at 130000, and now lifter and camshaft again at 145,000 miles. I feel that GM should back their product. I had a 95 Chevy Silverado that I sold with 360,000 miles and never had any issues except fot transmission at 250,000 which is expected. I have all receipts showing proof
