general problems of the 2019 Chevrolet Silverado 1500 - part 1

Lifter issue with damaged cam shaft. Described to me as well known defect still being worked out with gm. Engine could have failed/exploded at any moment. It is being repaired but is very expensive.

2019 5. 3l v8 engine. Dfm lifter failed while towing travel trailer on interstate. Lifter ended up seizing in pushrod and shearing camshaft lobe. This put my family at risk while being parked on shoulder of the interstate. Research and talking to others has shown that this is a common occurrence with these 5. 3l v8 engines. Having to replace the engine with no reimbursement from gm.

Chafed or broken wiring harness (very common) — this is the most frequent cause on newer gm vehicles. The factory wiring harness to the mass airflow (maf) sensor is too short or secured with an overly tight zip tie. Engine movement causes the lin bus wire to chafe and break internally near the connector.

The engine was making a noise which was obviously coming from internally. Chevrolet dealer examined the engine and found metal shavings throughout. Lifter roller was stuck and grinding down the camshaft. The engine was at risk of failure which could have been catastrophic if it occurred while driving . Especially at higher speeds . This could have resulted in a crash.

The contact owns a 2019 Chevrolet Silverado 1500. The contact stated that while hauling a camper and driving approximately 60 mph, the vehicle lost automotive power while the accelerator pedal was depressed. The vehicle was towed to a local independent mechanic, where it was diagnosed with a rod bearing failure due to a possible collapse lifter. The local dealer was contacted. Upon further investigation, the contact associated the failure with gm service bulletins: 19-na-218 and pip5776c with contributing factors to the failure. The manufacturer was made aware of the failure. The failure mileage was approximately 90,000.

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.

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.

Dfm failure caused major engine damage and loss of power on interstate.

The contact's husband owns a 2019 Chevrolet Silverado 1500. The contact stated that while driving approximately 35 mph, the check engine warning light illuminated but disappeared the following day. The contact stated that approximately four days later, after refueling the vehicle, while stopped at a red light and attempting to make a right turn, the vehicle stalled. The vehicle was pushed to the side of the road and towed to the residence. The vehicle was then towed to a dealer where it was diagnosed and determined that the fuel pump module needed to be replaced. The contact stated that dtc: p129f was retrieved. The vehicle was repaired. The manufacturer was notified of the failure. The failure mileage was approximately 23,600.

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.

6. 2 motor failed in cylinder number 2.

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 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.

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.

The engine malfunctioned then the engine light came on. I finally got home turned it off and let cool down. Tried to restart and same issue.

I was driving my truck on a clear sunny day and the alarms started to go off and it said I had no oil pressure, so I pulled off the road quickly and turned it off. I called a wrecker service and they took it to the dealership where I live and they told me the oil cooler line had ruptured and it locked up my motor. I had to replace it with a new motor. Upon further investigation I found there was service bulletin out for 2019 silverados for the oil cooler line rupturing. I was never notified of the problem.

The contact owns a 2019 Chevrolet Silverado 1500. The contact stated that while driving 25 mph and approaching a red traffic light, the vehicle stalled. There was an oil message flashing on the screen instructing the driver to pull over. The vehicle was towed to an independent mechanic, and the contact was informed about the gm customer satisfaction program: n212326940. The local dealer was contacted and referred the contact to the manufacturer for assistance. The vehicle was not diagnosed or repaired. The manufacturer was contacted and confirmed that the VIN was not under recall. The contact was referred to the NHTSA hotline for assistance. The failure mileage was approximately 42,000.

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!.

6-12-26 while driving down the highway the engine suddenly started running rough. Multiple warning lights came on and sounded like a muffled backfire. The truck has confirmed lifter failure as well as camshaft damage enough to where they're replacing an engine I still have no eta on getting my truck back the truck only has about 72 or 73,000 miles.

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.

The contact owns a 2019 Chevrolet Silverado 1500. The contact stated that while driving, the vehicle failed to exceed 6 mph. The check engine warning light was illuminated. The vehicle was taken to the local dealer, where it was diagnosed and it was determined that the abs module needed to be replaced. The dealer had retrieved dtc: p2074. The vehicle was repaired, but the failure reoccurred. While driving in stop-and-go traffic, the vehicle failed to accelerate and unexpectedly shifted into park(p). The contact stated that the vehicle failed to restart, and the battery was disconnected and reconnected. The vehicle was then taken back to the local dealer, and additional diagnostic tests were recommended. The contact was informed that the torque converter and transmission needed to be replaced. The vehicle was taken to an independent mechanic, who stated that the failure was related to technical service bulletin: 23-na-018. The manufacturer was contacted and informed that the dealer should use a flow chart. No assistance was provided. The failure mileage was approximately 100,000.

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.

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.

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.

The lifters failed at 106634 miles. This caused the motor to lose power while driving. The dealer confirmed and said a new engine was needed. There were no warnings just immediate failure of a part Chevrolet knows very well is an issue but won't do anything about.

Engine oil cooler line leaking from crimp. Same issue csp n212326940 gm distributed but my truck was not covered for some reason.

While driving home from my way to work, an esc sensor alert went off on the dashboard display. My truck was sent into limp mode, could not accelerate anymore and as soon as I pulled off onto the side of the road the truck died. I was never able to start the truck again. Determined it was an engine lock up when I tried to turn the crankshaft by hand.

Own a 2019 Chevrolet Silverado 1500 with approximately 76,896 miles. The vehicle experienced sudden coolant loss and overheating while driving and became disabled to the point it would not restart. The vehicle required towing to a repair facility. The symptoms appear substantially similar to known gm cooling system/oil cooler line issues addressed in other silverado programs and complaints, however my VIN is excluded from coverage. I am requesting review for goodwill assistance and escalation due to the nature of the failure, the maintenance history of the vehicle, and the safety concern created by sudden overheating and loss of power.

This truck has a recall on it but by specific VIN numbers mine doesn’t fall into the VIN number but had the same catastrophic oil cooler line failure, which is in the recall which caused the engine tool expire with 40,000 miles on it. Truck is like brand new general motors will not honor the warranty even though it’s the failure that’s in the warranty makes no sense.

Was driving along at 65mph when I heard a pop and then truck shut off said loss of oil pressure along with a few other warnings. Managed to cost to the side of a hwy that has no shoulder msg came up saying put in neutral to start did so the motor cranked but would not turn over like it had lost all compression. Got towed to a local repair shop spun a main bearing which in turn broke the timing chain that then took out the oil pump. Had no prior issues have kept up and regular maintenance well before the recommended time intervals. The hwy I was on is very busy two lane road with no shoulders and very limited passing opportunities could have very easily been hit. This has left me with a need for a total engine replacement that are quite expensive on a vehicle that was bought because it was not part of the gm recall as it is outside the listed as effected yrs.

On Tuesday April 28 while I was driving the engine suddenly started making a strange noise and the engine died. It would not restart. I had it towed to the dealer and was told the cam shaft “spun” and destroyed the engine. I am now having to replace the engine at a cost of $11,000!.

I have a 2019 Chevrolet high country, have always kept it serviced and maintained. Driving down the road it randomly lost power, wouldn't let me (driver) give gas, started shaking and making loud clanking noise from the engine. Was able to pull over to the side of the road, recorded the noise it was making. Called a tow company to get it towed to the nearest Chevrolet dealer ship and they confirmed that the engine was no longer good. Related problem to the 6. 2l motor issues. They are requested for a new motor.

: experienced engine failure. : as of now, vehicle is at the dealership since ( April, 24 2026 ) dealership - sunshine Chevrolet - arden nc 28704 ( vehicle is available for inspection ) : I was on my way to work on interstate 26, near asheville nc when I noticed sudden shaking and loss of power. I had to immediately get the vehicle into slower lane of traffic, before exiting the interstate. : problem has been confirmed by the dealer : yes > warning lights did appear. ( service engine ) also ( oil pressure warning light ).

I have a 2019 Chevrolet trialboss with a 5. 3 l engine and the lifters went out on this vehicle! now it’s needs a new engine! and there seems to be a huge trend with this.
