NHTSA Complaint #11673784 — 2018 ALFA ROMEO STELVIO

My 2018 Alfa Romeo Stelvio was diagnosed by a certified Alfa Romeo dealer with a major engine defect involving coolant mixing with oil. The diagnosis revealed internal failure likely stemming from the oil cooler or head gasket, and the parts estimate alone was over $17,000 — not including labor. The dealer confirmed the issue but stated no recalls apply and denied warranty coverage. The car showed early signs like minor overheating and coolant loss, but no clear warning lamps or check engine lights until the issue escalated. This defect significantly increases the risk of engine failure, overheating, or loss of power while driving — posing a serious safety concern. I have since discovered multiple other owners reporting the exact same problem in Alfa Romeo forums and consumer complaint sites. The dealer has confirmed the issue but refused support. I believe this may reflect a broader design flaw affecting many vehicles and should be investigated for potential recall.
