2021 Alfa Romeo Stelvio Owner Complaints

The engine oil cooling system failed on my 2021 Alfa Romeo Stelvio 2.0T at approximately 45,000 miles. The failure caused engine oil to contaminate the engine coolant system, creating a brown/milky “milkshake” substance inside the coolant reservoir and throughout the cooling system. The dealership diagnosed the issue as an internal oil cooler/oil filter housing failure. The contamination affected multiple cooling system components, and the dealership estimated approximately $8,300 in repairs, including replacement of multiple cooling system parts. The manufacturer offered partial goodwill assistance toward the repair cost. Prior to diagnosis, the vehicle displayed low coolant and low oil symptoms. I had to add approximately one quart of engine oil. I am concerned this premature failure could create a safety risk due to possible overheating or engine failure while driving. The vehicle had been maintained normally and had not previously overheated. The issue was confirmed by an authorized Alfa Romeo dealership.

As I am merging onto the highway during high traffic, I hear what sounded like a shotgun/explosion. I immediately swerve to the side of the highway, scared, alarmed, and in fear of causing a major accident. As I inspected the car, I noticed no damage to the body but only to find my sunroof glass was shattered. According to the experts, they stated "there is no apparent impact zone, and if there was, it would show damage inconsistent to what actually occurred here." Looking at the images/videos taken from the incident, the sunroof appeared to have imploded outward, and nothing penetrated the glass from outside forces aka. a rock, a bird, debris, etc... The entire sides of the sunroof all broke outwards. The corporate people at Alfa Romeo said it was due to 'outside forces' but with no evidence of such. This is clearly a manufacturer problem, and if not addressed, can cause severe injuries and in worst case, fatalities. The car has less than 8k miles and is brand new. I am traumatized, concerned and frankly upset about this whole ordeal.
