I was driving in a city at 30 miles per hour no acceleration and no load. I lost oil pressure, dumped all the oil out of the crankcase and then the engine locked up. I had it towed to my mechanic shop that i have work done. The technician diagnosed it as a failed oil cooler pressure supply line. Where the solid steel line crimps to a rubber oil hose, that connection had not been applied enough pressure and the rubber line became separated from the steel line.
Power train, Engine, Fuel/propulsion system, Mar 13, 2026
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.

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.

Power train, Engine, Mar 7, 2026
The oil cooler line is leaking, and the vehicle is available for inspection upon request. This safety concern is addressed under GM Program N192220080. The Hazard is Present: The leak is active. The risk of total line detachment and engine seizure is the same in Texas as it is in Alaska (the US state the GMC recalled the exact same part). An engine seizure and loss of propulsion is an immediate danger to passengers within the effected vehicle, as well as the other vehicles on the road. The Admission of Defect: GM’s offer to provide the part (Part #85136335) confirms that my vehicle’s hardware is part of the failed batch. The vehicle was inspected by an authorized GMC dealership on 01/14/2026, confirming the leak and potential safety hazard with continued driving of the vehicle. The issue was submitted to the GM Customer Care team, Case #[XXX]. The only warning of the defective oil cooler line leak was oil on the ground underneath the vehicle after driving.

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

On Wednesday, January 7th, 2026, my wife and I were traveling North on the Northeast Extension of the Pennsylvania Turnpike (476) at approximately 9:00 pm. A check engine light came on with no other symptoms, we start to get off the next exit. While still on the highway, the motor turns off with a warning to put it in neutral and restart. It would not restart and coasted off the exit and into a convenience store parking lot. There was noise, just turned off. We got stuck in the town for over 2 days before getting a tow 209 miles to the mechanic shop. We were miles from any mechanic shop and tried to troubleshoot while waiting and to no avail. First mechanic had to send it to a second because it looked like the engine had seized and that was confirmed at the second mechanic shop. Apparently the bearings in the lower end seized. The only thing they could offer was to replace the motor. It had proper amounts of fluids and didn't overheat. The motor replacement is approximately $10,800.00 in addition to having no vehicle there was additional towing and breakdown expenses (food and lodging for 2 nights and 3 days)

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.

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

While pulling a small trailer to go hunting, the engine just lost all power while merging onto the freeway. I had to pull over to the shoulder in high speed traffic because the truck had no power and had an odd clanking sound. When I took it to the dealer for repair, they stated that the lifter failed and also damaged the cam. This required a full engine rebuild. When the dealer went to test drive the truck with the new parts, ANOTHER lifter failed and also affected the cam again which required another rebuild.

On January 15, 2026, my wife was driving our 2019 GMC 1500 Sierra Denali and the lights on the dash came on with the truck losing power. I made to my wife later in the day and was able to drive the truck to the dealership only achieving 15mph for about 5 miles. The Mike Bell Chevrolet Dealership in Carrolton GA stated that my engine was knocking and needed to be replaced. I took my truck the John Thornton Buick GMC dealership on January 22 to get a second opinion and they stated the exact same thing stating the engine needs to be replaced. The dealership is stating the remanufactured replacement issue is over $10,900. My truck has over 271,000 miles.
