2019 Chevrolet Silverado 1500 Engine Problems

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

My head, my transmission in my Silverado 1500 6 speed has had rough shifting since I bought it had 29,000 miles on it. It also has been looked at for the rough and they said it was normal now at 100,000 miles by train ships out of gear while driving and coming to an idle at random spots, took it into a train shop Westland transmission. They said I need all new transmission which I think this should've been fixed a long time ago with the rough shifting the recall and lawsuit needs to add the six speed trans to the eight speed intense speed that GM is officially getting served on.

V8Component Affected: Electrical System / Power Train (Transmission) / Engine Cooling & WiringDescription of the Safety Defect and Incident:While operating the vehicle, severe electrical degradation occurred due to a catastrophic failure of the factory body-to-chassis grounding system. Upon professional inspection by a certified mechanic, it was discovered that the primary ground wires had suffered extreme thermal degradation, with the mechanic stating that the wiring components "almost melted in his hands" upon physical touch.Because the vehicle's manufacturing-defective ground strap severely corroded and failed, the high-amperage electrical current redirected itself along an unintended path of least resistance: directly through the transmission shifting cables and internal wiring harnesses. This extreme electrical bypass caused extensive thermal damage, melted critical electrical insulation, and permanently fried the Transmission Control Module (TCM) and internal transmission components, causing total mechanical failure.Why this is a Critical Safety Hazard:Fire & Thermal Risk: The failure created an active thermal event under the hood. Electrical current reaching temperatures high enough to melt heavy-duty wiring harnesses poses an immediate vehicle fire risk while operating or parked.Sudden Loss of Propulsion: The electrical short directly compromises transmission communication, risking an uncommanded shift into neutral or total loss of motive power while driving at highway speeds, creating a severe crash hazard.Manufacturer Action / Request for Investigation:General Motors recently issued Customer Satisfaction Program #N252515590 specifically to address this exact "body-to-chassis ground strap corrosion" defect on 2019–2024 Silverados.

The company had a complimentary repair of the known issue of bad oil cooler lines. It oblast short period. I now own the vehicle and it still has leaking oil cooler lines why should it not be replaced by GM since the lines leaking or coming apart and possibly blowing up and engine is a known problem. Would like gm to replace it under the program they already had offered

AFM causing engine tick. I am reporting a radiator failure on my 2019 Chevrolet Silverado 1500 equipped with the 6.2L V8. The vehicle developed an active coolant leak from the radiator assembly. The coolant reservoir level dropped significantly after normal driving, and coolant was visibly leaking and collecting underneath the vehicle. The truck initially began running warmer than normal, approximately 215–220°F, before the leak was fully identified. After topping the system with the correct DEX-COOL coolant, the coolant level continued to drop and an external leak became clearly visible. The vehicle was subsequently parked to avoid engine overheating or further damage. The original radiator carries GM part number 84152439. I have since been advised that the current GM replacement radiator is part number 85575815. I was also informed by GM dealership personnel that radiator failures involving this application are currently being investigated. My concern is that a sudden radiator failure can result in rapid coolant loss and overheating, potentially causing engine damage or vehicle disablement while driving. This is particularly concerning because the temperature gauge may initially remain near normal even while coolant is being lost. I am requesting that NHTSA review radiator failures on 2019 Chevrolet Silverado 1500 models, particularly vehicles equipped with the 6.2L engine and heavy-duty/enhanced cooling package, to determine whether there is a pattern of premature radiator cracking, tank/seam failure, or other coolant-loss defects that warrant a safety investigation, service campaign, or recall.

At 82,000 miles, cylinder number 6 lifter collapsed resulting in a bent push rod. I have since replaced the cam, lifters, push rods with an AFM delete kit for Texas Speed knowing that the same problem would occur if factory parts were used again. One would think that a newer vehicle should last longer than 82K miles with all the technology today. Oil changes were always on time between 3 and 5k miles. Unfortunately, I'm cursed with knowing how to work on vehicles. Is there anything that GM can do with my out-of-pocket material costs of $2500.00? Love the truck ... but very discouraged and may have to go back with a Ford!

We recently had a brand new engine installed In our truck that only had 70k miles and only 7 years old due to white smoke coming out of tail pipe. The day after receiving the truck back after having the brand new engine installed the truck was not operating properly then gave me a bunch of warnings and then the brakes wouldn’t work and the steering wouldn’t work. I informed the dealership that installed the brand new engine and they had the truck towed back to their shop just to look at it for 3 days and proceed to tell me there was no issues they could find. Picked the truck back up just to have the same issue happen not even a month later. I was able to document the warnings and issues while they were happening and provided those to the dealership when we drop it off for the second time after getting a brand new $13k engine installed. If you would like the video I captured of the warnings I will happily send them.

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

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.

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.

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.
