The starter started dragging about a year ago and on November 12 the 2019 GMC truck would not start. We had it towed to Harper GMC in Minden, La. They told us the motor was locked up. This vehicle has a little over 40,000 miles on it. Has always been parked in a carport out of the weather and still looks brand new. I see where 2021 GMC trucks have a recall on the motor and this is the same problem with our 2019.

Truck cut out going across the road almost got hit due to the vehicle stalling then about a mile down the road the check engine light came on parked it took it to my mechanic and after the incident it was throwing a cylinder misfire code. Cylinder one when the mechanic got in there was completely shot and I had to have a new motor. No warning no lights could have potentially caused a major accident.

It is the same issue with 2021-2024 6.2L engines that have already been recalled. I have to replace lifters and cam because of the issue.

- Lewiston, ME, USA

My truck had a ticking, knocking on the bottom end of the engine as I was driving home with my children. When i pulled into my driveway, the low oil pressure light came on and the truck began to stall while the back of the truck was till in the roadway. Several cars had to come to a complete stop to avoid hitting us, right where my children were seated in the back. I was able to limp the truck into my driveway. The following day I attempted to start the truck. It started hard and immediately gave me a low oil pressure light. I shut the truck off and called the dealership. The dealer wanted $3000 to just diagnose the problem. I had to pay out of pocket to get the truck towed to a private shop. The private shop started the truck and attempted to drive it to reproduce the issue. The truck engine seized and I had to pay to have it towed back to the shop. I then had to purchase a brand new crate engine from GM and pay to have it installed. The seized engine would not even roll over, so the cost of labor was increased due to them not being able to unbolt the torque converter on the engine. My engine is a 6.2l and GM told me based on by truck being a 2019, that it was not included in the recall. So far, the engine replacement has cost me $19,000.

Was driving at about 55 mph and vehicle popped up with warning and said shift into neutral to restart. I tried to and all power turned off. This was at around 8 p.m. so no headlights or anything. Luckily got it stopped without hitting anything. Had vehicle towed and motor was locked up. Spun bearing they said. Same issue apparently as other 6.2 liter engines have been having.

I keep getting low oil warning even after oil change

- Fort Mill, SC, USA

Engine suddenly lost power at highway speed. Truck was still running so I was able to get off the highway. Engine failure was caused by bent lifter. Lifter failure also caused damage to the camshaft. Vehicle was at dealership for significant time with a large repair bill that GM is not willing to cover due to the vehicle being 5 weeks out of warranty

- Canton, MI, USA

Engine Failure. 1. The lifter in cylinder 5 failed (dropped) this prompted me to bring the truck in initially. 2. Upon further inspection all the cam bearings were scored and out of spec. Waited 4 months for an engine replacement from GM. Eventually I cut my losses and sent the block to a machine shop. This was all paid out of pocket. Truck had 74,000 miles on it.

- Hudson, NH, USA

Sudden lost of power while driving. I was driving on the i95 and out of nowhere the vehicle shut off in the middle of the highway. It was a scary moment because I could of been in serious accident. All the engine signs were displayed on the dashboard.

- Hollywood, FL, USA

At approximately 61,500 miles, the engine malfunctioned while cruising on a 4-lane highway at 45 MPH. The problem was diagnosed by an independent mechanic as a crankshaft rod bearing failure. This failure happened despite all recommended maintenance being performed with specified parts. This failure caused a safety concern as the vehicle was in motion at the time of the failure, increasing the potential for a collision due to the vehicle becoming disabled on a highway. The engine was replaced at a cost of approximately $13,500 parts and labor. Vehicle was out of service for two months due to a waiting list on replacement L87 engines.

- Pomona Park, FL, USA

Defective out cool oil return line on v8 6.2L engine. Causing the truck to lose oil immediately due to being under pressure. Caused complete engine failure and required a new engine. That took 4-5 months to complete. Located in park city Utah a cold weather location. Not part of the 2019 recall for the same failure that gmc did in Canada and Alaska for a defective cool oil return line. When I called gmc to talk about it they referenced my vin and said it had no open issues and that they couldn-??t talk about it.

While towing a trailer on Highway 77 in northern Wisconsin, my 2019 GMC Sierra 1500 experienced a sudden engine failure. The dashboard lit up with alerts for the engine, transmission, ABS, and traction control. I safely pulled over in a 55 mph zone with narrow shoulders and heavy truck traffic due to nearby road construction. The truck lost all power, and I had to block the driving lane to transfer the trailer to another vehicle, creating a hazardous situation. There were no prior warnings or issues. The truck had regular service at independent shops, and I had checked and topped off the oil that morning. Lahti Towing & Service recovered the vehicle, changed the oil (no metal shavings), and replaced the camshaft sensor, but the truck still wouldn-??t start. They then towed it to Rhinelander GMC, where a broken timing chain was diagnosed, requiring a full engine replacement. The vehicle is currently at Rhinelander GMC and available for inspection. I have photos of the dashboard alerts and data from the GM app documenting the incident.

My engine has a loud knocking/ticking noise. I have had one mechanic look at it. He has me taking my truck to a dealership this week. He believes the known issue with GMC's 6.2 engine is taking place in the engine in my 2019. From a verbal conversation with the dealership, they believe the same. I was advised to complete this form ASAP.

- Dwight, IL, USA

Pulled up to a stop sign, the engine shutoff and would not restart. Had the vehicle towed to the dealership. Received a call that the engine will need to be replaced. The code is a P0016. Same code as the other 6.2 L87 GM motors, but is not currently under the recall. They found no metal in the oil pan and the engine only has compression on cylinders 2 & 8. Make no mechanical sense. Before this, I had no engine lights, I had no oil burning, I had no smell of oil and the truck ran fine. No loss of power or any other issues.

- Norcross, GA, USA

I have a loss of power in the motor with engine codes diagnosed by the dealership of P0016, P0017. These are the same codes and symptoms that are included in the 2021 through 2024L 87 6.2 L motor recall. My motor is a 2019 edition but having the exact same issues. I know these are the same motors and is having the same issue. started having loss of power in May 2024 with engine codes coming in September 2025.

- Leaf River, IL, USA

Engine developed a clicking sound. Took to dealership and was diagnosed with rod and bearing damage requiring an engine replacement. Was fortunate to have inspected before engine failure while driving. No warning before the failure. I believe there is a known issue with the 6.2 L engines.
