On Sunday October 12th, 2025, we were driving in Grand Rapids,MN when our truck (2002 Silverado [XXX] ) suddenly lost power. We were on a main highway without shoulders. The truck would not restart. The truck would not shift out of park to be rolled/pushed off the road. After about an hour, a tow truck arrived and towed the truck to our home ($200). We connected the ODB2 Code reader and found code P129F. After a bit of research, this code is related to a failed Fuel Pump Control Module (GM 13544060). The module is superseded with GM 13554821. We found this fuel control model is the subject of a recall (N252516900) on various GM vehicles that share a similar body design and year to this truck with this exact module. A semi-local dealer had the replacement part (GM 13554821 - $60) and we were able to replace it Monday morning to bring the vehicle back into service. I am requesting the following - Expand the recall to include any vehicles with this known-faulty Fuel pump control module INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

On January 16, 2025, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE25001 after receiving complaints and field reports concerning engine failures in MY2019-2024 GM’s full-size truck and SUV T1XX platform equipped with the L87 6.2L V8 engine. These complainants alleged engine bearing failures resulting in knocking and growling noises from the engine’s bottom end and in some cases more severe consequences such as broken connecting rods leading to engine damage, or engine failure. If the engine fails during vehicle operation, the vehicle will lose propulsion, increasing the risk of a crash. On April 24, 2025, GM issued recall 25V-274 to address the concern with L87 engines produced between March 1, 2021, and May 31, 2024. GM cited the root cause as a supplier manufacturing and quality issues. GM’s recall remedy will be either an oil change to an oil with a different viscosity or engine replacement depending on the results of the remedy inspection procedure. To date, ODI has received 1,157 allegations of engine bearing failure. GM submitted 55,464 reports in total, with 29,752 unique VINs. ODI continues to receive allegations of L87 engine failures which fall outside of the scope of recall 25V-274. Based on GM’s recall, ODI will close this PE. NHTSA will continue to investigate complaints of engine failure outside the scope of recall 25V-274 as part ofEngineering Analysis (EA25007).
