My vehicle has now been at the dealer two times for issues with the engine. The first time they said my lifters needed to be replaced. They rebuilt the engine to replace the lifters and other engine parts. I picked the truck up and two days later I was driving home and the engine quit on me and I had to pull to the side of the road. I tried to restart the vehicle several times and then it started up, but only for one more mile and it completely went out again and would not restart. It had to be towed to Shumacher GM dealer in West Palm Beach. This definitely put my safety at risk since the truck shut down while driving. It seems that GM is having major issues with their engines. It is presently being inspected by the dealer and GM. I have not heard back of what the issue is, but I believe the engine will need to be replaced. I did not receive any warning messages or had no clue that the engine was going to shut down.

What 2023 GMC Sierra 1500 owners say
Most recent owner complaints, unedited.
Information related to GMC 25V274 recall for 2023 GMC Sierra 1500 6.2L. Recall oil change inspection and change of oil to higher viscosity performed summer of 2025 (prior to my ownership). On May 17, 2026 the Truck lost engine power without warning and would not start again. Fortunately I was on a road and location where I could coast into a parking lot, but again the vehicle provided no advanced warning of any issue. Towed truck to dealership and determined that exact engine problem noted in recall had indeed occurred to engine. So GMC recall efforts to inspect and change oil had NO effect on the engine defect. Engine was replaced.

My 6.2 motor in my 2023 GMC AT4 truck has blown up. As part of the recall that GM has on this motor it passed the "pico test" at around 50k miles or so ( I can provide the paperwork) and then this past week with 63k miles or so the engine developed a miss and eventually by the time I got it to the dealer there was a significant "engine knock". The service center called the next day and said there was definitely a engine failure and I was lucky to have made it to the dealer. The vehicle is at the dealer waiting on a new engine. I was quoted 2 weeks but we are passing that time frame now. GM needs to be held accountable for this mess.
My truck's engine failed in April 2026 and was replaced. Approximately 7,000 miles later, the replacement engine failed as well. After bringing the vehicle to the dealership for another engine replacement, the newly installed engine seized during the dealer's test drive before the repair could even be completed. As a result, I am facing additional delays and have been without a reliable vehicle for an extended period.
On XXX, at approximately 2:30am, about 30 hours after purchase, a 2023 GMC Sierra Denali Ultimate suffered catastrophic engine failure in [XXX] during a planned 20 hour trip. The vehicle had about 49,007 miles at purchase and 49,411 miles at the time of failure. The check engine light appeared during the trip. Over five hours into the journey, shortly after passing through a one-lane construction zone with no shoulder, the truck made noises, then lost driving power and began slowing among highway traffic. The dashboard displayed "LOW OIL PRESSURE STOP ENGINE," code P0016, and a transmission warning. I had to move into another lane to reach the shoulder. The sudden loss of propulsion at 2:30am created a serious crash risk because the truck could have been struck by nearby traffic or become disabled on the one-lane road without a shoulder. The engine had received the GM L87 recall remedy on XXX involving a change to 0W-40 oil. Despite this remedy, the engine failed while the vehicle was moving. The repair order lists replacements for the engine, radiator, oil cooler lines, intake manifold and gaskets, spark plugs and wires, water pump gaskets, high pressure fuel lines, fuel pump gasket, and battery. The GMC app currently lists a "Required Product Emission Recall" for the fuel pump power control module and states that module failure can interrupt fuel flow to the engine. However, the federal safety agency VIN lookup, refreshed XXX reports zero unrepaired recalls. The reason for this discrepancy is unknown, as is whether the fuel pump recall condition contributed to the incident. I am reporting this sudden loss of driving power and engine failure despite the prior L87 recall remedy because these conditions may pose a serious safety risk.

The contact owns a 2023 GMC Sierra 1500. While driving at 30 MPH, the vehicle jerked and lost motive power. The vehicle was restarted and driven at reduced power to the dealer, where unknown electrical repairs were performed. The failure persisted, and the vehicle was towed to a second dealer, Grissom Chevrolet (181 S Interstate 20 Frontage Rd, Pecos, TX 79772), who replaced the engine. However, the failure recurred, and the vehicle was towed back to the first dealer, who diagnosed that the spark plugs and other unknown parts needed to be replaced. After the dealer performed the unknown repairs, the check engine warning light illuminated when the contact's son-in-law picked up the vehicle. The contact's brother, an independent mechanic, diagnosed that the catalytic converter and other unknown parts needed to be repaired. The contact filed a lemon law claim. The manufacturer was notified of the failure by phone. The failure mileage was approximately 50,000.
A 6.2 engine operated as expected for 75,000 miles. I turned a corner at an intersection, and had a loud knocking in the engine occur. For the first 75,000 miles, there wasn't any unusual engine noises or oil consumption.Seconds later the engine light illuminated on the dash, reduced engine power, and every safety light within the dash was going on and off. I managed to drive slow and return to my residence and have the truck towed to the dealership to have the engine replaced. As many have learned, the recall from GM states to either pass a PICO test and change to 0W-40, or have the engine replaced if necessary. My concern is that the replacement engine is the exact same engine with the exact same components that assuredly will fail due improper design, production, and overlooked components that attribute to such failure. The crankshafts are being found to have values of "peaks and troughs" within the finish that are many times out of given specifications. The extraneous pressures created by the Dynamic Fuel management system over time are creating stresses and friction that the designated oil and oil pump are not compensating for. These mechanical stresses over different durations, seem to be part of the cause of the engines failure. The replacement engine came with a warranty that only extends to an odometer reading of 150,000 miles. I no longer have confidence in a manufacturer that is enforcing false resolve upon a customer as a solution. The new engines of replacement have been failing as well. This result exhibits a fact that shouldn't be ignored. The new engines have the same components and are due to fail, just the same as the original. I would like the manufacturer to resolve this failure by offering a "true" solution. A proven remedy and a documented warranty that assures the manufacturer stands behind the product. GM sells a new product that fails and then recalls the engines to replace with the same failed components and lack of warranty.

1) Driving on highway and lost acceleration power would only go 50 mph/went into limp mode. Dealership stated VIN number had not been released into national safety recall. Replaced crank shaft valve and was told once VIN was released I would be reimbursed, to date still in dispute. 2) low oil light came on, upon checking oil was extremely low and oil had just been changed during #1’s repair. Had towed to dealership. Engine was replaced under recall. Was charged for water pump which is in dispute. 3) shortly after and well before oil change would be due, low oil light came on again. Towed back to dealership dip stick bone dry. I asked the store vehicle inside. Called for diagnosis at 5pm stated no codes no leaks found needed to investigate further. 4) 9am following day received a vm the truck had been repossessed by GM (note there is only 10K remaining on a special order 72K truck) dealership has not responded to requests to determine if the issue was fixed or request for service ticket to know what had been done. GM Financial claimed dealership told them it “was just a part under warranty” well the warranty came from the replacement engine that was under the recall…upon talking to reinstatement dept I was informed the vehicle was not fixed. I will be redeeming the vehicle but I do not think it is right to repo during a safety recall and then auction off not fixed as that is a safety issue! Once redeemed, it is also a safety issue to get from auction lot to be repaired.
