I have experienced no engine failure or symptoms to date. However, I am filing based on a documented pattern of L87 engine failures in 2025 and 2026 production vehicles, confirmed by multiple GM dealership technicians, which suggests that the manufacturing defect underlying NHTSA Recall 25V-274 may not have been fully resolved by GM's stated production improvements dated June 1, 2024.

GM excluded 2025 and 2026 model year vehicles based on a claimed manufacturing fix. …
