2019 Chevrolet Silverado Engine Problems

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.

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.

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.

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 leaking at the crimps.

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.

The contact owns a 2019 Chevrolet Silverado 1500. The contact stated that while driving 15 MPH and turning left, the low oil pressure and several unknown warning lights illuminated. The vehicle was pulled over into a parking lot. The contact stated that there was no oil in the engine. The vehicle was towed to an independent mechanic to be diagnosed. The mechanic associated the failure with NHTSA ID Number: 25V274000 (ENGINE AND ENGINE COOLING); however, the VIN was not included in the recall. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 30,000.

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.

Engine Oil cooler line

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.

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.

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.
