The vehicle check engine light came on and a message displayed "Reduced acceleration. Drive with care." My acceleration was very slow but that was the only symptom, although I was driving speeds under 55 MPH. I took the vehicle to GM with CEL Code P078 and they replaced the high pressure fuel rail. Two days later the CEL came on again with code P228B. I was driving on the highway when the message came on and I could not accelerate the vehicle. If I tried to push the gas pedal more than halfway, I would lose both speed and power. I could not maintain my highway speed very well and could only accelerate if I slightly pressed the gas pedal. This is a serious safety concern because it may cause an accident if I am not able to maintain speed on the freeway. Additionally, this is of concern because I rely on my vehicle to pull a camper, and with this condition, I would be a "sitting duck" with my family in the vehicle. GM continues to diagnosis the issue but has failed to respond in a timeline and satisfactory manner.

Vehicle started making an odd noise and was immediately taken to the dealer. Engine light did come on after the noise started. Dealer confirmed that there was an issue with the camshaft/lifters and that they have had to perform this repairs to 8 other trucks with the same 6.2L engine. (Original repair bill is attached). Dealer performs the repairs, takes the truck for a test drive and within a few miles the engine completely seizes up stranding the truck in the middle of the road. They believe it was a separate issue that caused the engine to seize up and now after 12k of repairs I will also need to purchase a completely new engine. Currently waiting on the price and availability of a new engine but was told I may have to wait a long time since this is such a common issue there aren’t many available. Would be more than happy to share additional Info as it becomes available.

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.
