Description of the Problem: While operating the vehicle, multiple warning lights illuminated including the Electronic Stability Control (ESC) warning light, the check engine light, and other unknown warning indicators. In addition, several warning messages were displayed, including “Service Engine Soon” and other unknown messages. When this occurs, the vehicle begins to overheat, the auto start/stop function becomes disabled, and the vehicle loses power and will not accelerate as expected. Component or System Failed / Malfunctioned: The exact component is unknown at this time. The failure appears to be related to the engine, powertrain, or electronic control systems. The vehicle and components are available for inspection upon request. Safety Risk: The vehicle’s failure to accelerate and overheating while in motion creates a serious safety hazard. This puts the driver and passengers at risk, especially if the loss of acceleration occurs in high-speed traffic, intersections, or on highways. Reproduction of the Problem: The issue has recurred multiple times. It has not yet been officially reproduced or confirmed by a dealer or independent service center. Inspections: At this time, the vehicle has not been formally inspected by the manufacturer, police, or insurance representatives. Warning Lamps, Messages, and Symptoms Prior to Failure: The problem is preceded by the illumination of the ESC light, the check engine light, and other unknown warning lights.

The car never showed signs of an issue, I got on the car with my two children, when I attempted to start the car. The engine started smoking and smelled like burned plastic. We got out of the car, the smoke went on for about 15-30 seconds. After that the car did not start. The engine's wiring was charred. I was informed by the dealer a ground strap failed. This ground strap is exposed to the elements at the bottom of the engine and it's prone to corrode, rendering it useless and causing the electrical wiring to overheat and potentially start a fire.

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.

I have had a sudden loss of coolant causing the engine to overheat. I have never had a leaking issue. But after research I’ve learned this is a common problem with this vehicle. My vehicle began to lose power causing the car to lose acceleration in traffic causing other vehicles to suddenly avoid hitting me and others. The problem has been confirmed.
