2020 Alfa Romeo Stelvio: check engine light

Filed Jul 13, 2026 · Engine · MA

Engine light came on. I was told by the first dealership that the coolant was mixing with the engine oil. There was also a vehicle at the shop there for the same issue. after doing some research online, it appears that this is a bigger issue. I bought the car at 20,000 miles and this began happening around 52000 miles. Given the low mileage, this is something that should not be happening to a newer car.

Back in December 2025 my engine light had come on, upon bringing it to the dealership I had found out that the engine oil and the coolant were mixing. A repair was done to stop this from happening three months later the same issue happened only the previous dealership was no longer servicing Alpha Romeos so I brought it to the only dealer left a mass. I was told that they botched the repair at the previous dealer. Now, three months later from then my engine light is back on again and the same thing is happening. but since neither truly actually repaired the issue now, I’m being told that there’s an issue with my engine. From the beginning when I first brought it to the dealership, this was not an issue. I was actually told that the engine was not misfiring at all, and the engine appeared to be good.My car was not the only one there for this issue so clearly this is a known issue. I also began looking online and realized that there are a lot of people that have this issue so I did bring it to Alfa Romeo‘s attention I feel like at this point the dealerships are making it worse because they’re not fixing the actual issue. I’m also being told this time around that, it was only a temporary fix which I was never told the first two times that they fixed it. No vehicle with 50,000 miles should be having these types of issues. I feel like there is a bigger issue that needs to be addressed within the manufacturer.

The vehicle suddenly loss power while I was driving on a busy interstate. I was almost rear-ended by the vehicle behind me. I had to coast my vehicle to the shoulder of the road crossing lanes of traffic without power! It was terrifying. I could have been wrecked our worse! The check engine lights flashed on saying: "Service Electronic Throttle Control" and "Start / Stop unavailable". I took the car to get it checked out and I was told that this is a common problem currently under recall for the 2018 models, but not my 2020. The mechanic says the scanner code is P008A, a fuel system problem which is likely a faulty fuel pump.
