2019 GMC Sierra 1500 engine complaints
Page 11 of 12: complaints 281 to 310 of 335, newest first, as owners wrote them.
While driving the vehicle, had a sudden “thud” from the engine compartment and immediately started getting error messages on the dashboard. When the codes were pulled, it said a misfire from cylinder number 8. The initial shop it was taken to was unable to diagnose the problem and referred me to the dealership. Upon inspection at the dealership, they stated that the camshaft and all the lifters needed to be replaced. The vehicle is still at the dealership waiting for this to be done. Upon doing some research, I have found that lifter issues are a very common occurrence in these vehicles. I was reading this morning about the investigation that the federal safety agency has started into issues with the L87 engine, which my vehicle has. If the investigation is concentrated on another issue, I would recommend that the lifter issue gets looked into as well. There is no reason that a vehicle with just over 100,000 miles and has had all the oil changes done on time, should suffer a failure like this that costs thousands so dollars to fix. I apologize for not including videos of the issue, I can’t save the ones that the dealership took. Please feel free to contact me if you need any further information or if I can be of further assistance. Thank you.
So August 29, 2023, at 46,000 miles, my engine failed completely with no warning or anything, while driving to work, was at the dealership until October 4th. Then December 10th, 2024 with 83,000 miles my engine failed again while my little brother and I were driving home late that night, on the highway at 70mph , suddenly losing power, causing us to be stranded on the side of the highway at 2am. Has been at the dealership since December 11th, with no eta in sight, and we're at 36 days and counting. A spac case was opened to escalate getting a part. This truck has been a problem and I want to get rid of it as its a safety hazard to myself, family members, and other on the road. GM customer service has also been giving me a runaround as well.
My 2019 GMC Sierra AT4 - Driving home from work on the highway car lost sudden power, All engine notifications appeared on dash and a very loud screeching sound happened. Was able to pull it onto the side of the road barely. Diagnosis from nearby shop was a lifter failure in cylinder 5 causing metal shavings to lock crank up. Total engine replacement. Car has 122,000 miles and every oil change done at 3,000 miles by GMC service technician since new and documented. GMC offered nothing when notified about the issue.
Engine failure with no prior warning 11/21/2023. We were on the highway. Truck made some noises and hesitated and stalled within 2 minutes. Thankfully, there was an off ramp and we were able to roll into a gas station. Had it towed to a GMC dealer. GMC dealer confirmed engine was blown. Dealer confirmed it's a known issue.
I was driving and my vehicle started to give me warnings to pull over due to low oil. When I safely pulled over and check. the engine oil cooling line was detached from crimp joint and leaked all the oil. Called the tow truck and took the truck to the dealer (Charles hardy chevrolet in Dallas GA) And they telling me that the engine is locked and it need to be replaced. There is a recall for the part but they telling me that my vin number is not part of it. Even though is exactly what the recall said it would happen
I have a 2019 gmc sierra 1500 elevation. The dash indicated low oil with 60lbs of oil pressure. I stop park my vehicle and see there is a puddle of oil underneath my truck. It appears to be leaking (extremely high flow rate) from the oil cooler lines where the rubber has given way from the metal crimping. Apparently after calling the dealership and reading online there isn't any type of recal for this issue even tho there is a Customer Satisfaction Program N212326940 implemented for Alaska and Canada due to the cold weather climate causing the failure. I live in western Pennsylvania and currently had a cold snap of 11°F. The dealership wants me to pay out of pocket and take my vehicle in to get diagnosed for service , which also means paying to have it towed to the dealership since it is un-drivable . Then pay for the very obvious service and file to see if I can be potentially reimbursed. This vehicle has less than 70,000 miles on it and is outside of the warranty. However this is a reported common issue online and even through the service department in Zelienople Pennsylvania because the tech. Told me they have the parts in stock because they do alot of them when I was inquiring into the issue.
While driving the transmission lurches forward when I give it gas after slowing down or when I come to a complete stop. Also it makes a shuddering type noise randomly when driving and it feels like the truck is about to shut off. These issues happen on multiple occasions.
Oil line separates causing massive oil leak causing engine to fail
2019 GMC SIERRA 1500, Fuel Injectors. This was a recall back in April of 2021. My vin is not on the recall list but am having the same problems. While driving the check engine light came on alone with no power check abs system and parking brake.
While driving the vehicle caught engine fire later exploding within seconds.
Right lifter went out & damaged the CAM Shaft which in turn damaged the engine The vehicle has been sitting at the dealership since August 1, 2024 & confirmed on August 9, 2024, stating that a new CAM shaft would need replaced or a new engine, which ever we choose. NOTE: Vehicle only has 40,298 miles on it I was driving to work on August 1, 2024, service engine light came on & was blinking & the breaking system lights came on, this was the only warning that I received.
The engine of the vehicle malfunctioned. The vehicle is available, but however it was taken to a certified dealership to be repaired. My safety and the safety of my three nieces, who were in the vehicle at the time, were put at risk as the vehicle all of a sudden staled in the middle of the Interstate while driving at 75 miles speed rate. The dealership repaired the vehicle by replacing the engine because the camshaft was scored, one of the lifters had failed, and a pushrod was bent. The only warning lamp/message was at the time of stale which read service ESC, Service parking break, and there was a third message but could not remember. I have only had the vehicle for sixteen months. The vehicle was taken in for it regularly scheduled oil changes and tire rotations. There were no issues or warnings prior to the engine replacement which cost me $8623.00.
2019 GMC Sierra 1500 SLT. Truck would not start on several occassions. By playing with brake, shift, and steering wheel truck would start again., Also would show warning notices, last one being {engine oil low-add oil}, even right after I just had the oil changed. This last time it would not start I paid to have my mechanic come to me to check it out. He tested a lot and thought it might be the starter so I then had to pay to have it flat-bedded to their garage. What he finally found was a BUNCH of wires worn through in a major wiring harness. It was caused by the wiring harness being next to the steering knuckle and the steering was wearing through the wires exposing bare wires. The mechanic and I see this as a major safety concern and a possible fire hazard. He has told me others have had similer problems . I believe this should definitly be a safety recall for these vehicles. My mechanic states that a new wiring harness olone is about $1500.00 plus a LOT of labor to install it. I do not believe that I should have to pay for a defect in GMC building this truck I have a picture of this mess of wires if you can help me with this. Don't know how to upload the photo I have but would gladly send it to you, Please respond back to this. Thank You Dennis Dorn
Check Engine Light came on while driving system scan states misfire cylinder 6 but resulted in the lifter being damaged as well as the cam shaft on a vehicle that has 108,000 miles. Prior to this I reported multiple times that it seemed that the transmission would slip and stuttered when on a incline and put in reverse. I was told it was a computer program issue and was charged for a software update which obviously did not fix the issue but ruined the engine.
Driving on the highway coming home from brother in laws house and the truck suddenly popped check engine, brake service and ESC lights came on dashboard while engine power was reduced causing sluggish performance. Made it home and put a scan tool and pulled a cylinder 3 misfire. Replaced spark plug and confirm it’s not an ignition coil problem. Brought to dealer and was confirmed the DOD lifter failed in other words AFM. Overwhelmed and couldn’t do anything but to pay and get truck back to working order told go ahead for replacement of parts for nearly $6k.
Lifter cam failure. Twice
Complete system failure while driving. Lost control of vehicle, no breaks. Had it brought to dealership. Lifter failure and bent rod, top engine failure which caused everything to malfunction. Vehicle has 88K miles on it. This is a defect. We had taken it in for the ticking problem in the past and they did nothing for us. Everything is documented. We are afraid that bottom half of engine was compromised. Do not feel safe driving this vehicle anymore. I do not want it to blow or lose control of vehicle again. This is a known issue and must be addressed. There was a service bulletin put out for my engine and there is an exact part by part that needs to be replaced, however GM is unwilling to listen to us at this time. Please look into this because this will happen to more and more consumers. This is very scary. What is the cost of a life?
Engine oil cooler line crimp connections are not properly crimped and leaking oil whether the truck is operating or sitting off. It also appears the flare or threaded connection has failed. I went to the GM dealership who said my truck wasn’t part of the recall but my lines are very clearly the same affected parts and would not be available for repair under the recall. I suspect there are other trucks like mine that were missed in the initial recall. I had the lines inspected at another repair shop but all the GM oil cooler lines were unavailable and no back order was permitted. There have been no warning lights for low oil pressure yet but the worst level I have seen so far was only 3 of 8 in quarts in the oil pan. I’m afraid of the lines blowing out on the road and causing a total uncontrollable engine failure and oil slick for other drivers.
With only 89K miles on my vehicle I’m having to replace 13K dollars worth of parts due to a known issue with the 5.3L V8 engine with the AFM DOD system that GM hasn’t fixed and refuses to help cover the cost cause I’m outside my warranty. I feel they need to extend the warranty miles and time frame due to the common occurrence of this issue
Engine Oil Cooler Line detached from Crip fitting. Vehicle: 2019 Sierra 1500 powered with 6.2L L87. GM has a published policy for a specific 530 vehicles, GM Claims my VIN was not covered hence no recall police "Customer Satisfaction Program N212326940" letter was released for subject VIN. It's clear, this issue exists beyond the scope of 530 vehicles. No know warnings existed prior to the incident. Vehicle has been repaired at owners expense and not supported by GM.
The lifter valves for the dynamic fuel management system have failed twice resulting in an immediate loss of power, rough driving, and low speed. To replace the first time, it cost $3500 at a mechanic. The 2nd time that it happened (8 months later), we now have to have the engine replaced and it cost almost $10,000. GM has refused to take any ownership in these faulty lift valves and someone is going to lose control of their vehicle when this occurs.

Oil cooler line detached from crimp while driving at highway speeds forcing the vehicle to an emergency stop on the side of the road. All oil pressure was lost immediately and entire underside of vehicle including tires, brakes, and wheels were all coated in oil. Known issue for same year, make, and model that has already been listed from the federal safety agency. But, apparently this VIN was not in the affected range.
According to inspection by my local GMC dealership, the engine oil cooler lines leaked/detached, as a result the engine assembly needs to be completely redone. When driving on the highway the car began flashing to immediately pull over and turn the vehicle off, the engine became very hot and was smoking and oil was found all over the ground upon inspection after immediately stopping the vehicle. This vehicle has been inspected by the Carlsbad GMC/Buick Dealership. There were no warning messages prior to this event. The car has consistently received all recommended preventative maintenance and oil changes. As a consumer I am now on the hook for over $15,000 in repairs, after complying with all maintenance recommendations from the manufacturer. There is an active recall for an identical model and make as this car for the same issue, the recall number is: N212326940 (customer satisfaction program number) and DCS5833 (Global safety field investigations number). I am very confused as to why this recall has not been applied to my vehicle.
