general problems of the 2019 Chevrolet Silverado 1500 - part 1

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.

Oil cooler line leak.

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.

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.

The engine experienced a failure in cylinder #5, confirmed by diagnostic trouble code p0305 (cylinder 5 misfire). The vehicle and engine remain in their post-failure condition and are available for inspection upon request. The problem was confirmed through diagnostic testing, which retrieved code p0305 (cylinder 5 misfire). The misfire is present whenever the vehicle is running and is reproducible. The vehicle has been inspected by a service center and diagnosed with a cylinder #5 misfire. The vehicle has not yet been inspected by the manufacturer or insurance representatives but is available for inspection upon request. No police inspection was required as there was no collision. The failure occurred suddenly while driving at approximately 45 mph. Immediately after the failure, the check engine light illuminated and the engine began running extremely rough. When during warranty, the vehicle was serviced multiple times for engine shuttering and skipping.

The contact owns a 2019 Chevrolet Silverado 1500. The contact stated while driving 65 mph, the vehicle experienced reduced power and failed to exceed 25-30 mph. The contact stated that the failure persisted while driving uphill. The check engine warning light was illuminated. The vehicle was taken to the dealer, where it was diagnosed and determined that cylinder #5 wall was damaged and there was oil found on the #5 piston. The dealer determined that the engine had experienced an internal mechanical failure and needed to be replaced. The vehicle was not yet repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 83,260.

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.

I have experienced a catastrophic engine failure due to the faulty gm dfm lifters and oil pump. I was advised that my vehicle will need a new engine. I know there is bulletin no. : 24-na-173 for my vehicle. I have contacted gm, and they advised that there is nothing they can do since the truck is out of warranty. I know they are under investigation for the 6. 2 l engine failure issues, and I feel as if this needs to include the 5. 3l engines as well. This is very disappointing since I purchased this vehicle new, and have meticulously maintained it. Perhaps the cpa needs to get involved as well.

Cylinder 5 missfire and I have 2 codes on my ob 2 scanner.

I am reporting a catastrophic internal engine failure in a 2019 Chevrolet Silverado 1500 at 87,600 miles. Prior to this event, there were no warning lights or symptoms. While traveling alone during the holiday on a remote, one-lane road with no shoulder, the vehicle suddenly suffered a loss of power. Every warning light on the dashboard illuminated at once, followed by shaking, misfiring, and loud knocking from the engine. Because I was on a one-lane road with no place to pull over, this created an immediate safety hazard for me and oncoming traffic. I had the car towed to the dealership ( where I bought the truck) confirmed the failure was a collapsed lifter and scored camshaft (which I found out to be a known design flaw in the 5. 3l dfm engine). The dealer said it was not under warranty. I felt held over a barrel by the dealership; they initially provided an inflated quote and told me it would cost approximately $1,200, not including tax and shop fees, just to put the engine back together if I wanted to tow it elsewhere for a second opinion. I was forced to pay over $8,395 under protest just to regain use of my primary vehicle after 42 days of downtime. Upon completion, the dealer provided a "lifetime warranty" on the replacement parts. This is a tacit admission that these components were never intended to fail during the life of the vehicle. Gm refuses to include this vehicle in its coverage list, treating a dangerous engine stall as a simple "out of warranty" repair. This is a systemic safety defect that requires a mandatory recall expansion before it results in a terrible accident. My understanding is that a class action lawsuit, harrison vs. General motors, for this same thing, but they say my car is not in it, I should have been put on notice for this so I could protect myself.

The contact owns a 2019 Chevrolet Silverado 1500. The contact stated that while driving at 40 mph, the low oil pressure warning light illuminated. An independent mechanic was contacted. The vehicle was taken to a jiffy lube, where it was diagnosed, and determined that the engine oil cooler line needed to be replaced. The vehicle was not repaired. The contact related the failure to customer satisfaction program: n212326940 (engine oil cooler lines detaching from crimp); however, the VIN was not included in the csp. The manufacturer was notified of the failure and informed the contact that the vehicle was not included in the csp and to call the NHTSA hotline to report the failure. The failure mileage was 145,000.

The engine locked up on the vehicle. Thought it was a starter issue, had it towed into a local repair show that I used. Diagnostic test showed that the engine would not turn. There was no warning lights or other symptoms. I understand that there has been a recall on the same engines from GMC from 2021 - 2024 and the case is now reopened to include the 2019 and 2020.

Original owner of 2019 Chevrolet Silverado 1500 truck with 5. 3l v-8 engine and 64,557 miles. On January 2, 2026 while driving on local state road, experienced sudden significant loss of power, engine shuddering during acceleration, ticking noise from engine compartment, and dash messages “service parking brake” and “service esc”. Could not safely maintain traffic speed as it became very difficult to drive. Was able to get vehicle off the roadway. Chevrolet service diagnosed as misfire cylinder 1, collapsed lifter, and damaged camshaft with out of pocket repair cost totaling $11,367. 16.

An apparent engine malfunction, causing the number 8 cylinder to retard and miss. Not sure if the l84 v8 engine s having the same issues as the l87. Just wondering. The vehicle has less than 90k miles and has not been abused.

Engine started misfiring and losing power and it became scary to drive this vehicle as it was not functioning properly. There was no issue prior to this immediate failure and the vehicle was recently inspected. The dealership is recommending a full engine replacement due to lifter failure.
