general problems of the 2019 GMC Sierra 1500 - part 1

I was on my way home from work and everything was driving fine and then I got 1/4 mile from my house and the motor started making a very loud grinding sound. I could barely accelerate. The issue happened out of nowhere. No issues prior to this happening. I was driving about 40 miles an hour when the issue started and I limped it to my driveway, luckily I was not very far away. I have a 3 month old baby and this was my reliable family vehicle. Who’s to say what could have happened if I was driving at a higher speed with my child in the car. When it happened it started shaking really bad. I checked everything that I could. It sounded like my motor was starving for oil. I decided to go ahead and change my oil to see if that could have been the issue. I had just changed the oil approximately 2000 miles before this. I changed the oil and filter. Went to start it up and still same very loud grinding sound, shut it back off and have not started it since cause I’m afraid to damage it further. I checked the oil that I drained out of it and looks like small metal flakes in the oil. No warning prior to this happening. Just out of no where it sounds and felt like my motor was going to blow.

The contact owns a 2019 GMC sierra. The contact stated that while driving at 20 mph, the check engine light began to flash. The driver pulled over. The vehicle was knocking. The contact stated that failure was due to premature engine failure. The vehicle was towed to the local dealer, where it was diagnosed with a cylinder 3 lifter malfunction. The vehicle had misfired. The vehicle was not repaired. The manufacturer was notified, but no assistance was provided. The failure mileage was approximately 77,000.

Engine ceased while driving and shutdown. Towed to dealership. Dealership ran diagnostic test and code p0016 came up. Its 6. 2 engine has recall on other years with similar issues.

Driving and truck started to misfire (due to collapsed lifter after shop diagnosis) that then made my truck do reduced steering assist and my wheel got super hard to turn that almost sent me in the ditch at 60mph and also turned off my electronic stability control and also turned on my service parking brake drove straight to the shop and parked it very lucky I did not crash and the fact that multiple people this has happend too gm need to recall from the 2019 and up for these lifters after reading about it.

The contact owns a 2019 GMC Sierra 1500. The contact stated while driving at approximately 70 mph on the interstate, the vehicle experienced a sudden loss of engine power and decelerated rapidly, nearly causing an accident. The contact managed to pull off the road, but the failure persisted. Additionally, the contact reported a prior history of excessive oil consumption. During a previous visit to the dealer, the contact was advised to shorten the vehicle oil change intervals from 10,000 miles to 5,000 miles to mitigate the oil loss. The contact stated that the dealer failed to determine that the excessive oil consumption was an early symptom of the current engine failure. The vehicle was towed to a dealer, where it was diagnosed and determined that the belt filter and the piston needed to be replaced within the camshaft assembly. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 80,000.

I had left work and pulled out of the parking lot to head towards the freeway. I had driven about 3 blocks and the truck made an indicator alert noise. My dash panel said reduced power mode or something to that effect. The truck felt as if it lost power. Luckily I was able to pull to the side of the road at which point I put it into park and shut it off. I waited a moment and then tried to restart it. The dash panel said something but it was too fast for me to read before it went away. The engine was cranking but it did not restart. I tried several more times before calling roadside assistance to have it towed to a nearby dealership. The dealership said that I would need to replace the engine $18,751. 92. They said the camshaft rpm are 0 while the crankshaft rpm is 2-300. Lifters and rockers are not moving. The chain is most likely broke as well. The fuel pressure is about 30 psi in the high side. It would be just as expensive if not more to try and repair the existing engine if it is even repairable which they wouldn't know until they took it apart at which point I would have to pay for that as well even if it was not salvageable. They would need to replace the oil lines and cooler as well because debris from the engine could be in them and would do more damage if not replaced. I had already replaced the oil lines and cooler within the last 6 months. The truck has 114,000 miles. My warranty still had 3 months on it but the mileage stopped at 100,000 so I am out of luck. When I researched online to see what it could be I saw there are known problems with this 6. 2 l87 engine and that many fail around 100,000 miles. There are other recalls but the 2019 was not included in the recall. If I choose to have the work done it will take several weeks in which I will now have to rent a car as well. Not much of a choice when I still owe $30,000 and they only offered me $9,000 for it as is with the bad engine.

The 2019 vehicle experienced a significant engine failure consistent with widely reported issues involving gm 6. 2l v8 engines in GMC sierra and Chevrolet silverado platforms. Prior to failure, the vehicle developed abnormal engine noise including ticking/knocking sounds, followed by loss of engine performance and mechanical failure. Vehicle diagnosis indicated internal engine damage requiring major repair or full engine replacement. The failure occurred despite normal maintenance and relatively low mileage for a modern full-size truck. The vehicle had no prior abuse, modification, or racing use. Based on technician feedback from December 2025 service call and publicly reported incidents, the failure appears consistent with commonly reported gm 6. 2l issues involving: connecting rod bearing failure crankshaft/bottom-end damage lifter or valvetrain failure internal metal contamination sudden engine seizure or loss of propulsion this issue presents a serious safety concern because sudden engine failure can occur during normal roadway operation, potentially resulting sudden loss of power inability to accelerate vehicle shutdown while driving increased crash risk in traffic conditions I am aware of numerous similar complaints involving gm 6. 2l v8 engines across multiple model years, including investigations and recalls affecting related vehicles and powertrains. My vehicle appears to exhibit the same or substantially similar failure characteristics. I request that NHTSA continue investigation into 2019 model-year GMC sierra 6. 2l engine failures and evaluate whether these earlier vehicles should be included in broader recall or warranty coverage.

The contact owns a 2019 GMC Sierra 1500 denali. The contact stated that while driving at an undisclosed speed on a local roadway, the oil pressure warning light illuminated. The contact stated that oil was leaking from the vehicle. The vehicle was towed to the residence. The vehicle was then taken to the dealer, where it was diagnosed, and it was determined that the engine had seized. The manufacturer was not notified of the failure. The approximate failure mileage was 71,000.

I have a 2019 GMC at4 and it has stalled on the highway multiple times and smokes every time I started. I have read that the engine in it has been recalled on multiple other years but the one I purchased needs a $25,000 repair and it’s not safe to drive. There is not a current recall, but I’ve read that this engine on almost all the other trucks and suvs that have it have had problems.

Engine knocking, constantly kicking into limp mode, shaking when driving. Taken to GMC and local repair shops. Limp mode will not stop kicking on. Now other issues will mean total engine replacement needed. Mechanic says it’s not worth repairing at this point. Only 109k miles on it.

My vehicle is at the dealership now - it wasn’t starting properly, started always getting low on oil which I took to the dealership for them to monitor- and then the check engine light came on- once that came on just last Thursday I did not drive the vehicle except to the dealership to be inspected - which my appt was Monday and they found metal shavings in the oil and said the whole engine needs replacement!.

While I was slowing down when approaching a red light, the engine abruptly shut off and had no warning or anything. Then once stopped the engine would no longer crank leaving me stranded in the middle of a busy roadway.

The contact owns a 2019 GMC Sierra 1500. The contact stated that while stopped, there was an abnormally loud sound coming from the vehicle. The vehicle was consuming an excessive amount of engine oil. The engine and transmission warning lights were illuminated. The vehicle was initially taken to the local dealer; however, the dealer was unable to determine the cause of the failure. The vehicle was later diagnosed, and it was determined that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the issue and referred the contact to the NHTSA hotline for assistance. The failure mileage was approximately 106,000.

The engine suddenly seized and now needs to be replaced. Regular oil changes, no leaks, and the engine just seized up and won't run. 5. 3l v8.

Lifter failure and camshaft failure twice.

Lifter failure cylinder #8, this is a 2019 GMC sierra denali 4x4. It has a 6. 2l engine. With 92823 miles on it. It would be nice if gm would do a recall on this year motor as well.

I was driving my vehicle on the highway doing normal highway speed, when I began to hear an odd noise coming from the engine area. I slowed down and moved into the slow lane at which time the noise became worse. The vehicle then lost power and I wasn’t able to get the vehicle to do over 40mph. I was able to exit the highway and limp my vehicle home. I had the vehicle towed to a GMC dealership the following morning. After about ten days, I was contacted by the dealer and was advised that I had an engine failure and that my vehicle required a new engine.

Dangerous lost of propulsion in traffic while my minor daughter was in the vehicle, I was driving my truck that has a 6. 2 engine GMC that is currently being reviewed engineering analysis ea25-007, I bought engine back in October 2025 and incident happen early March 2026 around 10,000 miles.

Engine shut off while driving and steering wheel wouldn’t let me turn and I drove up on a curb into someone’s yard , there should be a recall on these trucks with the 6. 2l in the year 2019, this is very dangerous I could of injured myself on injured someone else. This needs to be addressed!!.

While driving down the highway experienced a partial loss of engine power causing jerky/rough operation, harsh shifting, and unpredictable behavior. Was told by the dealer service manager that it was likely a misfire in one of the cylinders. After diagnostics and servicing that included changing spark plugs, wires, and a full engine service it was later confirmed to most likely be due to a stuck lifter and will require a complete engine replacement. I have subsequently learned that this is a common problem with this l87 engine and may be an early indicator of failing crank bearings associated with a recall for later model years of my same vehicle. Seems to me that recall ought to be expanded to include earlier models with l87 engines.

Driving down the interstate 35 in tarrant county, texas. Engine locked up. Towed to dealership. Dealership determined that engine is locked up. Had dealership verify oil level was okay and they confirmed that it was. Oil had been services two weeks ago. Engine is a 6. 2 l but not the l87 block. Milage on the vehicle is 149,752.

The 2019 GMC sierra at4 with the 6. 2l v8 engine began making a rattling or tapping noise at 45 mph. No warning lights appeared on the dashboard. When starting the engine and idling, a similar noise can be heard from the engine. I bought the vehicle used from a dealership one month ago, with 80,000 miles, and the second issue is the complete failure of the blind spot warning system on both mirrors. It was a one-owner vehicle with a clean carfax. I am scheduled to take the vehicle to the dealership's service department for a full inspection.

This truck is equipped with the 6. 2l l87 and the motor seized up and shut off with no dash light warning and I stalled and rolled over a curb! this is very dangerous and now I have to pay 10k + out of pocket for an engine replacement! truck has low miles this is unacceptable and it needs to be in the recall , this is dangerous and it hurts people !.

The contact owns a 2019 GMC Sierra 1500. The contact stated that while driving at various speeds, the vehicle lost automotive power; however, the vehicle maintained electrical power. The check engine warning light was illuminated. The vehicle was towed to a local service center, where it was diagnosed and determined that the battery needed to be replaced. The vehicle was repaired; however, the failure reoccurred. The vehicle was taken back to the same local dealer and remained for additional investigation. The contact attempted to restart the vehicle several times and shift into different gears; however, the failure reoccurred. The local dealer was contacted, but the vehicle was not diagnosed or repaired. The manufacturer was notified of the failure and referred the contact to the NHTSA hotline for assistance. The failure mileage was approximately 103,000.

Engine light came on, along with 'service esc' and 'service parking brake' I drove it to my local GMC and it continued smoking and they told me that if I drove it like that it could blow up the engine. They mentioned a recall on these types of trucks but they said the warranty on my vehicle had expired at 60000 miles. Yes, I took it to rogers GMC in hermiston and the diagnostic is, "mechanical: valve lifters - remove and replace" totaling repairs to about $7000 before this nothing was wrong, I drove it to work everyday and one evening when I turned it on the dashboard lit up and it started smoking.

Engine oil pump solenoid. Diagnostic code p06dd.

The dfm program in the engine caused the lifters to fail and bend a pushrod which in turn scared the cam shaft. There were no signs leading up to this. It caused the traction control and brake systems to be compromised. I took vehicle into a gm dealer and had it diagnosed.

Engine loss of power many different engine code took it to the dealership. Now they say lifters, rockers are loose and worn,broken,the cylinder 5 misfire, engine needs rebuild at 88,000 miles. Dealer wants over ten thousand dollars to take apart and repair.

The contact owns a 2019 GMC Sierra 1500. The contact stated that the vehicle made an abnormal rattling sound while idling. Additionally, while driving at 45 mph, the message "reduced power" was displayed, the check engine warning light illuminated, and the vehicle stalled. The contact was able to coast to the shoulder of the roadway. The vehicle failed to restart and was towed to the dealer, where it was diagnosed and determined that there was no compression in the engine. The dealer determined that the engine needed to be replaced. The dealer advised the contact that the repair was not covered because the VIN was not under recall. The vehicle was not repaired. The manufacturer was not contacted. The failure mileage was approximately 126,000.

While driving my 2019 GMC sierra with approximately 119,000 miles the engine suddenly made a loud bang, started shaking violently, backfiring, and missing out. Took it to dealer. They diagnosed the problem as a rod failure with camshaft damage. Quoted repair cost $12,000. After repair, they were doing a 25 mile test drive before returning the truck to me. After only 20 miles, the engine completely failed. Now it needs an entire new engine. I am waiting for them to reply what the cost is. The truck was maintained exactly as required in the owners manual at general motors dealers.

After a really bad cold snap noticed oil spots on my driveway, after further inspection noticed the oil cooler lines were leaking from the crimps. Got in contact with gm because there was a customer satisfaction program for my year model- n212326940- they told me it did not apply to my truck but it is a know issue, and now I’m having to come out of pocket for it.

The contact owns a 2019 GMC Sierra 1500. The contact stated that while driving at 45 mph, the vehicle stopped unintendedly. The message “low oil pressure - shutoff engine” was displayed. The contact stated that the vehicle was towed to an independent mechanic, where it was determined that the failure was due to rod bearing failure. The local dealer was contacted and confirmed that there was no warranty coverage on the vehicle. The vehicle was not diagnosed or repaired. The manufacturer was contacted and confirmed that there was no warranty coverage. The failure mileage was approximately 105,000.

Catastrophic engine failure. Engine failed while driving and lost all oil pressure. Nearly cause accident.

For the past month I have noticed my truck has been dripping oil, I pulled the shield off and saw my engine oil cooler lines leaking at the crimp points. I’ve seen gm put out customer satisfaction notice but when I tried to have the dealership fix mine they said mine is covered under any recall or warranty. If the line comes uncrimped at highway speeds I’ll lose all my oil where the trucks engine could lock up and lose all forward motion and in my eyes could cause a crash.
