NHTSA Complaint #11687959 — 2018 ALFA ROMEO STELVIO

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 messages “Service Engine Soon” and others appear immediately prior to or during the failure. These warnings occur before the loss of acceleration and overheating. Additional Notes: The failures are ongoing and have occurred more than once, raising concerns about reliability and safety.
