general problems of the 2019 Chevrolet Silverado 1500 - part 2

The contact owned a 2019 Chevrolet Silverado 1500. The contact stated that while driving on the highway at approximately 40 mph, the engine started making abnormal sounds. The vehicle had experienced engine failure. There were no warning lights illuminated prior to the failure. The contact allowed the vehicle to coast to the shoulder and shifted to park(p). The vehicle was towed to the dealer and the contact was informed that the engine had imploded. The vehicle was repaired out of pocket. The manufacturer was not notified of the failure. The failure mileage was 131,000.

I am writing to formally express my frustration regarding the ongoing issues with my vehicle. The vehicle continues to overheat, the check engine light repeatedly comes on, and it has cut off unexpectedly. The tire air pressure sensors as well. These issues have persisted despite multiple repair attempts. I initially brought the vehicle to the dealership in December 2024, and again in March 2025 and now the vehicle is having the same issues to date December 2025. On both occasions, the vehicle remained at the dealership for over a month for repairs. Unfortunately, the problem has not been resolved. Each time I inquire, I am given different explanations as to why the issue cannot be fixed, which has been extremely frustrating and concerning. Additionally, I am being charged for services that I do not fully understand or agree with, especially given that the original problem still exists. Due to the lack of resolution, I have also contacted GMC directly to file a formal complaint. At this point, the ongoing delays, lack of clear communication, and unresolved mechanical issues are unacceptable. I requested a clear explanation of all charges, as well as a concrete plan outlining the steps needed to finally fix my vehicle. Please provide the appropriate point of contact and advise on how this issue will be resolved promptly. I expect immediate attention to this matter. Thank you.

I was driving on the interstate, when all my dash lights came on. When stationed, it would vibrate and have excessive smoke come from the exhaust when I would start driving again. After arriving to my destination there was an unusual burning/smokey smell when I got out of the vehicle. I got it scanned and it said it was a cylinder 2 misfire. I replaced the spark plug, coolant, gaskets. Still wasn’t fixed. Then I replaced the fuel injector. Still not working. The mechanic said the oil psi was 30. The vehicle was also burning thru gas and oil quicker than usual. Took it to the dealership and they said it needs a whole new engine and warranty is unsure if they will cover it or not.

The contact owns a 2019 Chevrolet Silverado 1500. The contact stated that while driving 45-50 mph, the oil pressure gauge suddenly dropped to zero(0), and a message stating that the oil pressure was low and to turn off the vehicle was displayed. The contact was able to pull over to the side of the road. Upon inspecting underneath the front end of the vehicle, the contact noticed that oil had sprayed underneath the engine compartment, onto the axle, and the front driver's side tire. The dealer was notified of the failure and referred the contact to the manufacturer for assistance. The manufacturer was notified of the failure and informed the contact that a claim was filed with the dealer. The contact was referred to the NHTSA hotline for assistance in adding the VIN to gm customer satisfaction program number: n212326940 (engine oil cooler lines detaching from crimp), which the contact related to the failure. The vehicle was not diagnosed or repaired. The failure mileage was approximately 106,000.

The oil cooler line was un-lodged from the metal crimp that secures it while I was pulling away causing total loss of all engine oil in a matter of seconds. Not only does the car immediately tell you to turn your car off to avoid catastrophic engine failure, but this is also dangerous for other drivers as the oil may cause a hazard for controlling the vehicle going through the oil.

Lifters failed causing complete engine failure gm won’t cover engine replacement but it goes along with the other engine failure lawsuits against gm.

While driving at a speed of approximately 55 mph, the vehicle suddenly displayed a flashing check engine light, esc error light and stability control warning light on the driver cluster. The vehicle made a loud series of noises and suddenly lost power. The loss of power reduced my ability to control the vehicles acceleration while in traffic creating an immediate traffic hazard. Garage recovered vehicle by tow and found lifter failure, camshaft and cam bearing damage with significant metal shavings throughout engine requiring engine replacement. Repair is estimated at $12,000.

The vehicle was shifting hard and eratically on the highway. All dashboard lights came on including the esc failure warning. A misfire in cylinder 2 occurred without any warning lights causing the vehicle engine to stop running on a highway. The mechanic repair shop did a disgnostic evaluation and reported a catastrophic engine failure from cylinder 2. The engine does not run and requires full replacement. The vehicle has only 80,000 miles.

While driving the engine suffered a catastrophic failure and died. Fortunately I was already coming to a stop when it happened. Had I been traveling at speed I would have been seriously injured or killed along with any other vehicles I may have crashed into. The Chevrolet dealership where vehicle was purchased new confirmed it was a catastrophic failure of the gm l87 engine which has knowingly been fraught with these failures. They cannot confirm the exact nature of the failure without dismantling the entire engine at my cost which I have not decided upon doing yet as it will be very expensive. As far as symptoms or warnings I heard a sound from the engine compartment immediately before the engine died.

Engine powered down and I was able to safely move to the side of the road and wait for a tow truck. Lifters on the truck failed which also damaged the camshaft that is currently being replaced.

Component or system failure: the engine valvetrain (camshaft and lifters) sustained severe internal damage, including camshaft scouring, confirmed during inspection and teardown by an authorized Chevrolet dealership. In addition, the rear differential was found to contain no gear oil when the fill plug was removed during inspection. The vehicle and components are currently at a Chevrolet service center and are available for inspection upon request. Safety risk: the vehicle experienced persistent drivetrain vibration and abnormal operation that worsened over time and ultimately rendered the vehicle non-operable. Internal engine damage and a rear differential without lubrication present a risk of sudden drivetrain failure, loss of propulsion, or loss of vehicle control, particularly at highway speeds. The vehicle is currently unsafe to operate. Problem confirmed: yes. Engine damage has been confirmed by the dealership during teardown. The absence of gear oil in the rear differential was directly observed during inspection. Inspections by others: yes. The vehicle has been inspected by an authorized Chevrolet dealership and by third-party inspectors associated with the extended drivetrain warranty administrator. Two inspections have been completed, and a third inspection has been ordered. No repairs have been completed as of this report. Warning lamps or prior symptoms: beginning around approximately 21,000 miles (2022), the vehicle developed drivetrain vibration. The vehicle was taken to a Chevrolet dealership at that time, but the cause was not identified or corrected. No warning lamps or messages are recalled.

Oil cooler line separated.

Originally the ecs message came up on the dashboard. The truck started running rough with the engine shaking and white smoke started blowing out of the exhaust. The problems started showing just as I was entering the interstate. I pulled over to the emergency lane. The truck was towed to a local dealer. They ran the diagnostic on the engine and found the #8 cylinder has no pressure and fuel was dumping into the engine. The engine had to be replaced. There was no warnings before this happened.

My 2019 Chevrolet silverado has experienced repeated engine issues, including a confirmed timing chain failure. The vehicle has been taken in for repairs approximately 6–7 times for the same or related engine problems. Most concerning, the vehicle has stalled while driving, creating a serious safety hazard. Loss of power while in motion puts me and others at risk of an accident. Despite multiple repair attempts, the issue has not been permanently resolved. The timing chain failure is a major engine defect and not expected for a vehicle of this age and mileage. I am filing this complaint due to the safety risk associated with engine stalling and failure.

Engine oil cooler lines leaking crimps. Crimps could completely fail losing engine oil and causing an accident. Dealer has confirmed the issue at last visit.

I was driving to work in the morning and started to accelerate to the speed limit of 45, and at about 35mph my truck completely shut off. I tried to push the start button while coasting with no avail. I pulled to the shoulder and tried to start it and it would slowly crank similar to a dead battery. I towed it home, then tried to start it later in the day and it started no issues, however ever since then there is a knocking noise from the lower end. I have had it parked for a few weeks and Monday December 15th it will go in to a chevy dealership for a diagnostic appointment. No there was no lights or warnings related to this, and this did put my life in danger being stranded on the shoulder of a road with limited room to pull off too early in the morning dark out.

I own a 2019 Chevrolet Silverado 1500. While driving 35 mph entering the flow of traffic, the vehicle lost power with the engine misfiring. The messages "service parking brake" and "service esc" were displayed. The check engine warning light was also illuminated. I drove to the nearest dealership the vehicle was diagnosed that cylinder #5 lifters had collapsed. The dealer informed me that the cylinder lifters needed to be replaced. Additionally, the camshaft would be replaced as necessary. The vehicle was being repaired. The manufacturer will be notified of the failure. The failure mileage was approximately 88,000. And I was informed that my service contract had expired less than 2 months ago.

“2019 silverado 5. 3l – engine knock + oil leak post-warranty install = fire/breakdown risk”.

"the vehicle has developed a recurring ticking/knocking noise in the engine, worsening under acceleration, accompanied by excessive oil consumption. This is a repeat issue after a warranty repair on June 6, 2022, where all 8 lifters on the right bank were replaced due to afm/dfm lifter failure. I believe the current problem is caused by metal debris from the initial failure scoring cylinder walls, rings, and bearings, leading to lower-end damage. Gm denied coverage under special coverage adjustment n242498000 despite the prior repair and matching symptoms in bulletin pip5623. Johnson motor sales quoted $14,893. 89 for engine replacement. The noise and oil loss pose a safety risk of sudden engine failure or loss of power while driving, potentially causing a crash. ".

When driving normal speeds to work on a county road, engine light comes on, service light comes on. There was a tapping noise and reduced power. Luckily, there was a sports field parking lot that I could pull into to get out of traffic. We had the truck towed to our house through our roadside assistance program so that we could determine what to do. If we had not been able to pull off the road as quickly as we did, we probably would have been hit by the semi that was barreling behind us. The truck had reduced power.

While driving down the road the engine quit. There were no indicators of anything wrong. Check engine light was not on. It just quit while driving. I didn’t have any notice. I wasn’t even able to get it off of the road. When it did come to a stop. The engine would not restart. I was stranded and had to get a tow. I had it towed to my mechanic and upon inspection, he says it needs a new motor. My truck has ran fine with all the regular maintenance up to this point.

As I was driving the vehicle it seems to be hesitating or jerking and when I tried to start it,it would say put your foot on the brakes to start,but my foot was on the pedal and it was slow starting. Days later the engine light came on,took it to the dealership and they told me it was a problem with the brake system. I bought the vehicle brand new,only 41,000 miles,on it now,warranty went out in June of this year. I very rarely drives it and now they saying its a 4,000 job to get it fixed.

While driving on 401 east the vehicle started to shake and the service esc error code came on. This vehicle has had all service completed at GMC and had no issues. Stopped at dealership and they ran diagnostic tests to report back the engine has failed and requires replacement. 6,2l l87 is all ready on recall replacement but this same engine is not covered even though same symptoms and diagnosis was determined by dealership.

Engine failure.

As I was driving down the highway the engine warning light came on and engine quit running immediately so I began to pull off of the road but couldn't get all the way off so it was sticking out on the highway I did put in park and checked oil level which was good, so I was going to try to push vehicle off the road more because there was semi-trucks and other vehicles going by at a high rate of speed but the shifter would not shift unless vehicle was running. So for the safety of my wife and myself we had to stand off into the ditch for about an hour waiting for help hoping no one slammed into our vehicle and there was some close calls.

One day when headed out of town I stopped and got gas immediately once getting back on the highway my dash lit up like a christmas tree, driving became uncomfortable as it sputtered when trying to give gas. I looked up a couple of the dash warning lights and it alluded to emission problems. I take the truck to the mechanic and he says that a head is cracked and the cam shaft needs to be repaired. This issue came out of nowhere, no prior issues as far as over heating or any dash lights on.

My 2019 Chevrolet Silverado 1500 with the 5. 3l engine developed a severe tick, misfire, and rough idle at only 93,000 miles. This was diagnosed as a collapsed afm lifter on cylinder 2. Gm 5. 3l afm lifter failure is extremely common in these trucks and causes sudden loss of power, misfires, and unsafe driving conditions. This is a known widespread defect, yet gm has not issued a recall. The failure happened without warning and required major engine disassembly. This should be investigated as a safety and reliability issue.

Component/system failure and availability for inspection: while driving at 70 miles per hour on the interstate, the vehicle suffered a complete loss of oil pressure. The engine warning light illuminated, and the vehicle simultaneously stopped operating. The vehicle and its components are available for inspection upon request. Safety risk: this failure posed a severe risk to my safety and the safety of others. The sudden and complete loss of engine function at highway speed could easily have resulted in a serious accident. I was fortunate the incident occurred in an area that was not heavily populated at the time. Under different circumstances, this failure could have led to life-threatening consequences. Reproduction/confirmation of the problem: the issue has not yet been reproduced or confirmed by a dealer or independent service center, but the nature of the failure was sudden, significant, and left the vehicle inoperable. Inspection by others: the vehicle has not yet been inspected by the manufacturer, police, or insurance representatives, but it remains available for review. Warning lamps/messages/symptoms: the only indicator prior to the failure was the immediate illumination of the engine light as the oil pressure dropped. This warning appeared at the same moment the vehicle lost power and stopped operating, leaving no opportunity to respond before the vehicle was disabled. Numerous comments and complaints with the same issue. Cust satisfaction n212326940, does it take someone getting injured or dying before this administration makes the compnay do the right thing?.

The contact owns a 2019 Chevrolet Silverado 1500. The contact stated that the “low oil” warning light was illuminated often, and the contact was adding oil to the vehicle every 2 weeks.

While driving "no oil pressure" alarm went off on my 2019 Chevrolet silverado. I had to immediately pull off to the side of the road, upon inspection the oil cooler line separated at the crimp joint. This is the exact failure mode as described in "n212326940 - customer satisfaction engine oil cooler lines detaching from crimp". I have my truck at a gm dealership and they said my VIN is not included on the TSB. I also contacted gm customer service and was told the same that my VIN was not effected by this issue. My failure is the same mode as the documented issue, it has to be related to part quality issue as described on n212326940. The gm dealership is charging me $2000 to replace the line.
