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.
Steering, Electrical system, Engine, Jul 2, 2024
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.

Lifter cam failure. Twice
Electrical system, Service brakes, Engine, Feb 28, 2024
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.

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.

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.

While driving on the highway, I got a message that said "low oil pressure, turn off engine" with red flashing lights. I could also smell burning oil and metal. I immediately pulled over and turned off my engine. When I exited my truck, I could see all of the oil that remained in my engine leaking onto the ground. My truck was towed to a local repair shop and they advised me that this is a common problem in this truck. The oil line blew likely due to a defective crimp. The mechanics can't repair the problem right away because this line is on a national backorder and there is no aftermarket option. This obviously happens too often if this part is on backorder. The mechanics believe there may have been damage done to the engine as a result of losing all of the oil on the highway.

Engine began having ticking noise. I took it to dealer for repair. Service department finds the lifters in my engine have failed and destroyed my cam shaft. They call me and explain it will cost $10,000 to repair. The service writer explains to me that they have 4 of these each week come into the shop. It is so common that they keep the parts in stock to repair. While I was waiting in the waiting room another person came in with the exact same problem. I later found that a repair bulletin has been issues for this issue but for some reason it does not apply to my vin even though it is the exact same problem.
