NHTSA Complaint #11692893 — 2023 CHEVROLET SILVERADO 1500

I am filing a complaint regarding a potential recurring safety defect related to Recall NHTSA 25V274 (GM N252494001). On July 29, 2025, my vehicle stalled while driving on the highway and was towed to Quality Chevrolet. The dealer diagnosed a failed starter and battery fuse link. During this visit, I authorized inspection for Recall 25V274, concerning possible crankshaft or connecting rod failure. I was told my vehicle was not affected but the dealer performed the recall remedy by changing the oil to 0W-40. On October 5, 2025, the vehicle developed a loud knocking noise from the engine. Quality Chevrolet diagnosed a connecting rod failure, the same issue identified in the recall. On October 10, 2025, I was advised that GM approved a full engine replacement due to internal damage. However, I was also told the new engine will use lower viscosity 0W-20 oil, contradicting the prior remedy intended to prevent this failure. This suggests the original recall fix was only a temporary measure, and the defect remains unresolved. I request that NHTSA investigate whether the current recall remedy adequately corrects this safety issue and whether GM’s use of 0W-20 oil could allow repeat failures. Additionally, I request assistance or reimbursement for vehicle payments, as my vehicle has been undrivable for an extended period due to a manufacturer defect. Thank you for your time and attention. I can provide all service records and diagnostic reports upon request.
