NHTSA Complaint #11708555 — 2022 CADILLAC ESCALADE ESV

My 2022 Cadillac Escalade Diesel (3.0 LM2) is experiencing a failure of the engine coolant control valve, a known defect addressed by GM under Special Coverage bulletin N252508341. The failure causes: •Intermittent reduced engine power •High-speed radiator cooling fans running continuously •Check engine light •Emissions system malfunction As a result of this condition, the vehicle fails emissions/smog testing and cannot be registered or legally operated in my state when the fault is active. The reduced power condition occurs unpredictably during normal driving, creating a drivability and safety concern, especially during merging, highway driving, and traffic conditions. GM has acknowledged the defect through a Special Coverage program but has denied repair coverage due to salvage title branding, leaving the vehicle with an unresolved emissions-related defect that affects safe operation and compliance. This issue is unrelated to any prior damage and occurs during normal vehicle operation.
