1) In May of 2025 I attempted to have the dealership complete the recall which the GM app told me to schedule. Related to the L87 engine failure. According to their own document my engine manufacture date was to be replaced a defective. The dealer told me that there was "no resolution for the issue and turned me away. (see attachments) 2) In June GM changed the procedure adding the PICO test. (see attachment) 3) In October I received the official recall notice and scheduled the test. At the prior service visit I had the dealer give me back the old oil filter. I took it apart and found metal fillings in it. I reported this to the dealer. The truck had the PICO test and passed. They told me that "the filter did its job and the metal in it was normal wear and tear". They replaced the oil cap and filled it with thicker oil. I was sent on my way, told to call if I had any issues. 4) On 2-6-25 while driving 65 MPH on the highway, the engine just shut off without warning. The dash displayed "press start again" while I was traveling at 65MPH. I was able to pull to the side and restart the engine. Service was scheduled and performed on 2-10-26. They found no codes in the computer and could not find the issue. 5) On 2-13-26 while driving 75 on the interstate the engine stopped, the display read "press start again". I was able to coast through traffic and got to the shoulder. After some time and playing with the buttons I was able to get the truck into park. Then I started the engine. I made it off the freeway and onto a side road. I drove a few miles further and stopped for a stop sign. The truck was again dead, displaying "press start again". After several attempts and my vehicle in traffic, I got it to start. It drove for a mile more and the truck was dead. I had it towed to the dealership where they are working in it. It requires a new engine. 6) GM failed and endangered my family while traveling at freeway speeds. They should buy back their failure.

There were no alerts within the interior to make me aware there was a problem. The engineer starting make a knocking sound at the time of failure. I had just gotten off the interstate when it failed. I spoke to a representative at the dealership and they informed me that the same engine will be installed, with a new oil type. I'm writing this given this will diminish the value of the truck, and I have to be worried about the engine failure happening again. Next time it could happen on the interstate with loss of power. I can't trust that to happen.

On 5 Feb 2026 I was starting my 4-hour drive back home. 15 minutes into my drive my truck lost power, several lights and the engine light came on. Truck was sputtering and making harsh engine noises and shut off on me. I was forced to exit Loop 2 (a major highway). Once I was able to restate the truck I went straight to the dealership. This truck had the recall done 15 Oct 2025. However, this issues still occurred. The motor gave out. Truck is 83K in mileage. well under 100K. Cost estimate is $6.5K. The technician informed me that a lifter collapsed in cylinder 5. This is clearly still part of the GMC recall issue for the 6.2L engines. What is my next step in this process. If I knew there was a major issue with these Trucks, I probably would not have purchased it. All maintenance has been done with same dealership to keep all service records excess able.

The Office of Defects Investigation (ODI) has received 1,157 reports of engine bearing failure failures in the L87 6.2L engine produced by General Motors (GM). Of the 1,157 reports received, 173 are outside of the scope of recall 25V-274. These engines are installed in Model Years (MY) 2019–2024 Chevrolet Silverado 1500 and GMC Sierra 1500, and 2021-2024MY Chevrolet Suburban and Tahoe, GMC Yukon/Yukon XL, and Cadillac Escalade/Escalade ESV vehicles. The subject engine failures were investigated as part of a Preliminary Evaluation (PE25001). GM determined that these engine failures were due to multiple supplier manufacturing and quality issues. GM issued recall 25V-274 to address the supplier manufacturing and quality issues produced between March 1, 2021, and May 31, 2024. Based on the issuance of recall 25V-274, NHTSA has closed PE25001. ODI continues to receive a significant number of reports of engine failure in vehicles outside the scope of 25V-274. This presents a potential safety risk that warrants further investigation. ODI is opening this Engineering Analysis (EA) to further evaluate the scope and severity of the potential problem and to fully assess the potential safety-related issues of vehicles built outside the recall scope.
