general problems of the 2019 Chevrolet Silverado 1500 - part 2

The contact owns a 2019 Chevrolet Silverado 1500. The contact stated that while driving at an undisclosed speed, the vehicle lost motive power. No warning light was illuminated. The vehicle was able to be restarted immediately, but the failure persisted twice, causing the contact to wait for the vehicle to restart. The vehicle was taken to the dealer, who determined that the engine had failed and needed to be replaced. The vehicle was not repaired. The contact related the failure to NHTSA action number: ea25007 (engine, engine, and engine cooling). The manufacturer was made aware of the failure. The failure mileage was approximately 72,500.

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 * compression on all cylinders**, **crankshaft and camshaft compression failure**, **pistons coated in oil and fuel with visible damage**, and a *?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 *,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. This sudden engine failure placed my family and other motorists in immediate danger, and the lack of w information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Engine problem had to get a new 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. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The engine died while in use. We were130 miles from home when the engine started making weird noises and a tapping sound. All the lights on the dash lit up and truck would hardly run. L had a independent car hauler haul the vehicle back home to a local garage. The vehicle has been repaired for $10,919 and paid $800. 00 to have it transported.

The contact owns a 2019 Chevrolet Silverado 1500. The contact stated that while driving at an undisclosed speed, the message "oil level low - turn off vehicle immediately" was displayed. Upon further inspection, the contact noticed a burning odor coming from under the hood, with an abnormal engine oil leak. The vehicle was towed to a local dealer, where it was diagnosed, and determined that the engine oil cooler line had detached. The vehicle was repaired out of pocket. Upon further investigation, the contact related the failure to the Chevrolet customer satisfaction program: n212326940 and Chevrolet customer satisfaction program: n192220080; however, the VIN was not included. The manufacturer was made aware of the failure. The failure mileage was approximately 160,000.

I was traveling home one night and the truck shut off while driving and lost all power, loosing all steering, braking power aswell as all my lights while traveling down the road in the dark. . When I went to start it again all I would get was a cranking noise but no firing. After 30 minutes of waiting the truck started again. In which I drove it 3 more miles before it shut down again. After that it would not crank nor start. I then had the vehicle towed to my local Chevrolet dealer, and they had notified me that the engine had failed and locked up. In the process it had also taken out the fpcm (fuel pump control module) aswell as the high pressure fuel pump located on top of the motor. Causing me to have a new motor from gm installed. I had no previous problems or lights before this had happened.

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!.

Out of specs crankshaft machining, excessive journaling chamfering & debri in the oil galleries have caused rod bearing failure resulting in total engine seizure. This is consistent with the NHTSA 25v-274 recall, of which identifies the 6. 2l v8-l87 engine as defective, resulting in 12 recorded accidents. However, this recall does not cover the 2019 model year.

I want to start off by saying that I have taken meticulous care of this vehicle and the intention was to keep this truck forever. However, that will not be possible after this incident. I was driving the vehicle at 60 mph when I noticed smoke coming out of the back of the vehicle and at that moment, the dash cluster started warning to shut off the engine immediately due to a lack of oil. I know there was plenty of oil in the engine because I just had the oil changed at a shop two weeks prior to the incident. I was able to verify that it was a total of 22 seconds from the time I noticed the smoke to the time I was able to pull off safely and shut the engine off. At that time, the engine had not seized, and I was able to manually shut off the engine on my own. I never tried to restart the engine and I had it towed to a shop that was nearby. 48 hours later the mechanic inspected it and discovered that the oil cooling line had somehow disconnected from the engine block, which had resulted in a catastrophic loss of oil. When that repair was made, the mechanic discovered that the engine would not start either by hand or automatically and deemed the engine to be seized. The engine in question is the Chevrolet 6. 2l l87 engine that was involved in a manufacturer recall for models made in 2020 through 2024. My vehicle is the 2019 model and although there have been numerous occasions that I’ve been able to find in only a short period of research that revealed similar issues with a 2019 l87 6. 2l engine, there still is no official recall on my specific model year. It was 1:30 in the morning, and I was rushing my sick dog to the emergency vet when this happened. Not only did it cause a major inconvenience trying to get him there in a timely manner, but our safety was also compromised in the process.

Oil cooler line leak.

While driving on highway with cruise control set at 65 mph, the engine started misfiring, lost power and multiple warning lights came on. This was the first and only time I had engine problems and I never had any warning lights come on prior to this incident. Dealer confirmed engine experienced complete failure and need to be replaced.

Oil leaking from the oil cooling lines where the rubber hoses connect to the metal lines. Thankfully caught before the rubber hoses completely blew out of the crimp. Gm issued two customer satisfaction programs (n212326940 & n192220080) for this issue, neither of which covered my vehicle. Clearly this was a much bigger issue. This is a safety issue as it can lead to a sudden oil loss, which could lead to a loss of propulsion, possibly leading to a crash. The oil is spread across the under side of the vehicle and could lead to a fire if it comes in contact with the exhaust.

Driving down road truck quit, no warning. Left granddaughter stranded on road. Towed to gm dealership. Diagnosis was complete engine failure. Vehicle is there now waiting for decision to repair.

I’d like to report a serious, ongoing safety concern with my 2019 Chevrolet silverado (5. 3 v8 53,028 mi) since Dec 2025. Over the last 4 months, I have experienced at least 20 engine failures/loss of power, with no engine light illuminated after restarting truck. These failures result in a complete loss of power, including steering and braking, posing a significant risk of a crash. Chevy said it would be hard to diagnose with no engine warning light on. Feb 24th, engine failure, warning light stayed on and towed truck to chevy. Truck on standby, repaired Mar 10th, replacing 2 oxygen sensors per diagnostics. Picked it up on March 11th, but engine shutdown again the same day and 4 additional failures while driving in my neighborhood, making the truck undrivable. I reached out to chevy service supervisor, juliana, but have received no response for the last 10 days. I urge NHTSA to investigate this defect as it poses a severe safety risk. Thank you for your urgent attention.

Vehicle info: 2019 Silverado 1500 6. 2l engine with 66,xxx miles. On 3/1/26 while towing my small snowmobile trailer I was driving on I-90 with cruise control set at 65 mph. Very suddenly and shockingly I heard an extremely loud knocking noise from the engine. I then witnessed several driver info messages stating things like "low oil pressure" "engine power reduced" among others and a check engine light. Amongst freeway traffic and now under no engine power and coasting I made an emergency lane change out of the passing lane and into the right lane and subsequently on to the shoulder of the interstate. Oil pressure was also noted to be very low during these events. I called a friend to pick me up off the side of the freeway and also had a local towing company get my truck and trailer off the side of the highway ASAP. This was a dangerous scenario and could've ended much worse. The vehicle is now at my residence and I am not sure what steps to take right now. As I am very aware of the current recall on similar models with the same engine. I have followed the issues and complaints of these trucks and suvs with the l87 6. 2l engine closely. I was under the impression that my vehicle was not included in the recall and I have always been very diligent about vehicle maintenance. I've been watching my truck closely for abnormal noises, power or oil pressure loss or any other strange symptoms I have not noticed any warning signs. I even recently switched to the new dexos approved 0w-40 engine oil that gm is recommending and/or mandating. This was very sudden and scary scenario. I do have video of the engine noises if theyre. Theyre not currently formatted for this report.

Incident description: while driving at highway speeds, the oil cooling lines on my vehicle suffered a catastrophic failure, resulting in a total loss of engine oil within seconds. To ensure my safety and avoid being stranded in high-speed traffic, I proceeded less than a quarter-mile to reach the nearest exit. During the cooling process after the vehicle was stopped, the engine seized due to extreme thermal damage caused by the sudden lack of lubrication. Safety risk: the sudden and total loss of engine oil at highway speeds presents a significant safety hazard. It creates an immediate risk of sudden engine stall or seizure while in traffic, which could lead to a high-speed collision. Furthermore, a high-volume oil leak onto hot engine components represents a severe fire risk. Technical evidence & manufacturer response: there are existing technical service bulletins (tsbs) for this specific vehicle model that explicitly identify these oil cooling lines as a known failure point. These tsbs state that failure to replace these lines can lead to the engine becoming non-functional. Despite this documented manufacturing defect and the clear safety implications of a sudden engine failure on a highway, Chevrolet has refused to provide a remedy, insisting that the engine replacement be paid for out-of-pocket. Requested action: I am requesting that the NHTSA investigate this known defect for a potential safety recall, as the failure of these lines constitutes a predictable and dangerous loss of vehicle power and potential fire hazard.

Engine oil cooler line leaks and crimping does not hold hose tight enough and slipped off crimp fitting. Line came completely off of crimp fitting and leaked all engine oil. Forced engine to be turned off and low engine oil marked on dash.

The contact owns a 2019 Chevrolet Silverado 1500. The contact stated while driving approximately 30-35 mph and exiting the interstate with a speed limit of 55 mph, the instrument panel, check engine, stability control, and several other warning lights illuminated. The vehicle felt like there was a misfire coming from the engine. The contact pulled into the nearest parking lot and turned off the vehicle. The vehicle was driven to the dealer, while not exceeding 25 - 30 mph. The dealer diagnosed the vehicle and determined that the camshaft was damaged, and the valve lifters had failed and needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The manufacturer opened a case regarding the failure. The failure mileage was approximately 97,000.

Engine oil cooler line leaking at the crimps.

The contact owns a 2019 Chevrolet Silverado 1500. The contact stated that the vehicle required an oil change every 1,000 miles driven due to excessive oil consumption. Additionally, there was an abnormally loud sound coming from the lifters. The vehicle was taken to a dealer and was diagnosed with excessive oil consumption and failures with the lifters. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 198,000.

Number 3 lifter spun into housing & ruined camshaft, send metal throughout engine. On trip to another state pickup started ticking, service motor light, service parking brake light and service traction icons came on and also messages on them. Had to drive slow to get to next town. Decided to go back home six hours away, very slow the ticking became knocking. Pulled over multiple times. Contacted dealer to look at next morning. In shop about two months. Dealer said number 3 lifter spun into housing and ruined camshaft that sent metal throughout engine. Had to have engine replaced for $12172. 42. Dealer replaced engine and other parts that needed replacing also. Our trip was ruined and had to purchase a cheap used pickup to get to and from work. Could only travel under a certain speed without ticking and knocking. Had to take different roads home because of slow speed. Trip had to postpone because of this motor issue. All icons, messages, ticking and slower speed all happened at same time. Had no warnings ahead of anything wrong.

Engine oil cooler line.

My husband, [xxx] son, my [xxx] mother-in-law, and I were traveling on the expressway at approximately 70 miles per hour in our 2019 Chevrolet Silverado 1500 with the 5. 3l engine when the dashboard suddenly lit up with warning lights and alarms. My husband looked in the rear-view mirror and saw a large amount of smoke coming from the truck. We immediately had to cross two lanes of heavy traffic to reach the shoulder and get off the roadway safely. When I opened my door, I could see that engine oil was pouring from the truck and running down the expressway. We were stranded on the side of the expressway for over an hour before my brother was able to come pick us up. The tow truck company advised that it would take several hours before they could arrive. During that time, vehicles continued traveling at highway speeds and did not slow down despite our disabled truck being on the shoulder. The truck was shaking from the wind and force of cars and trucks passing by at high speeds. This created an extremely dangerous situation, particularly with our [xxx] child and my elderly mother-in-law in the vehicle. The truck was eventually towed to a local repair shop, where the mechanic determined that the engine oil cooler line had broken at the crimp, causing a significant oil leak. The repair required replacement of the oil cooler lines and related components at a cost of $2,109. 92. Had we continued driving even briefly, the engine likely could have been severely damaged or destroyed due to the rapid loss of oil. This appears to match the known issue described in gm customer satisfaction program n212326940 regarding oil cooler lines detaching from the crimp on 2019 Chevrolet silverado trucks. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The oil cooler lines cracked due to cold weather and oil spouted out of the engine. Truck was immediately pulled over when the chime went off, however the engine still seized up and needs to be replaced. No warning lights before, just the chime at 0 oil pressure. I see that canada and alaska has this part recalled and I want to know why it’s not recalled everywhere. No oil was leaking prior to this incident. This left us stranded on the side of the highway and we now have to purchase a new engine with only 65,000 miles on it.

Engine was running at the mechanic shop after getting serviced for spark plugs ,wires, new radiator was installed,and transmission service. The engine was running on the lift for the mechanic to top off transmission fluid. The engine stop by itself. Went to restart the engine no start just extending cranking. The mechanic shop has the truck trying find the issue why did engine stop while running.

"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.

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.

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.

6. 2 gas engine was knocking and shaking while driving it engine is currently being replaced , but not finished yet mechanic thinks some rod bearings are bad and maybe some pushrods no warning lights came on.

The contact owns a 2019 Chevrolet Silverado 1500. The contact stated that while driving at an undisclosed speed, the check engine warning light illuminated. The vehicle was parked in the driveway, and the contact became aware of a puddle on the ground underneath the vehicle. The contact thought that the puddle was coolant, but discovered that the vehicle was leaking oil. The vehicle was taken to the dealer, who determined that the oil cooler line had failed and needed to be replaced. The vehicle was not yet repaired. The contact related the failure to the customer satisfaction program: n192220080 (engine oil cooler lines detaching from crimp – canada and state of alaska only); however, the vehicle was not included. The manufacturer was made aware of the failure and advised the contact to file a complaint with the NHTSA hotline. The failure mileage was approximately 118,000.

Motor only has 41000 miles and uses 1 quart of oil every 700 miles.

Engine oil cooler line blew off of engine while at highway speed. Lost oil and seized engine.

As I’m driving, the vehicle began shaking and ticking sounds could be heard inside the cabin. A check engine light lit up on the dashboard. The idle was rough and it sounded like metal thrashing in the engine so I turned on my hazards and shut the vehicle off in the middle lane of the street. It didn’t want to turn over a couple times but when I was finally able to get it to start again it made the loud ticking and thrashing sounds. To prevent more damage I put it into neutral and had to push it with the help of bystanders to the closet parking lot putting us and other drivers at risk. I had the vehicle towed to the local chevy dealer for a diagnostic and they claim a catastrophic engine failure and recommend complete engine replacement. There were no symptoms of this prior.

The contact owns a 2019 Chevrolet Silverado 1500. The vehicle was taken to the dealer for an oil change and the contact was informed that the engine oil coolant line had detached from the crimp joints, causing an oil leak. Prior to the maintenance service, oil stains were found on the ground of the garage floor. The vehicle was not repaired. The contact stated that a week prior to the failure, there was an abnormal coolant odor coming from the vehicle and was entering the cabin from the a/c vents. The vehicle was taken to the dealer, where a pressure test was performed, and the contact was informed that the radiator was cracked. The vehicle was not repaired. The vehicle was taken to firestone for a second opinion, and it was confirmed that the radiator was cracked. The vehicle was repaired. The manufacturer was made aware of the failure and referred the contact to the nhsta hotline for assistance. The failure mileage was approximately 40,000.
