2018 Alfa Romeo Stelvio transmission problems

Filed Jul 6, 2026 · Electrical, Fuel system · FL

My vehicle has been subject of multiple recalls, however the current recall is a significant one and has been pending for months with no end in sight. I am concerned The manufacturer and dealers are not taking this seriously and the delay is causing additional damage to my vehicle. Additionally quickly googling my vehicle will show that it has fuel pump and acceleration jerking and lag issues that are extremely, extremely, common and troubling. I am also still having the service engine soon issues described in recalls and other forums related to throttle cable. Either none of this has been addressed by the manufacturer or the repairs so far have not been sufficient if it is still so common. On behalf of all Stelvio owners I demand these recalls and issues be addressed in a timely manner. This is going to cost us additional grief, safety issues, and repair costs. The biggest being my safety and my family's safety when we are riding in this vehicle, the acceleration issues are very noticeable and are getting worse. The symptoms are -exactly-what is described online and also as part of the recall. I don't even have the option to get it fixed there is no parts to fix available. This is a very nice vehicle, but this is getting old not having repairs done and the dealers running out of parts etc. Waiting months and months for repairs. - Fiat, Alfa Romeo and their dealerships do not seem to be taking this seriously - at all, they should have pride in their products like the owners do when we buy them. I want my Stelvio to be the best it can be, fully safe, and fully functional.

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 several incidents with my Alfa Romero Stelvio losing power while driving, This problem has been going on for quite some time, i have had several parts changed out with the same results a few weeks or months later. I took the vehicle to Jim Ellis Alfa Romero for repairs and told them the vehicle was losing power while driving and was told that this problem has occurred on several Stelvios. I left my car with Jim Ellis and a few days later I was told all was good. I didn’t even get a mile away before I loss power again. I brought it back to Jim Ellis and left it again and a few hours later they called and said that the Stelvio needed a new turbocharger that would be $4000 plus installation fees. How is this possible if you told me you had taken care of the issue, and the car didn't even make it a mile.

My car has had numerous issues/errors and drivabilty concerns over the last 3 years with the automatic torque vectoring (ATV) system. The vehicle has unstable/unusual driving when the system is malfunctioning and the system does not store any error codes when the car is turned off. The vehicle has been to 2 different dealers more than 6 times and they are unable to find the root cause. I have to drive straight to a dealer to have the codes read as soon as there is a malfunction because it all gets erased when the car is shut off. This is a safety issue that the manufacturer cannot figure out how to fix on my car.

While on a hiway, with cruse on, stopped for a red light. While stopped the engine shut off. I pushed the stop-start disable buttion. The car acclerated into the intersaction before I braked it to a stop. Luckely there was no one infront of me and no cross traffic or we would have wrecked. The car then went back to idle and has been fine since.

There's a problem called etc error. It has happened 5 times since 9500 mileage. And now car has 15900 mileage. Every time it happened when I was on highway trying to accelarate. When that problem occured, I suddenly lost power and had to pull over in the middle of traffic. Then I needed to shut down the engine and restarted, after this action power was back on with engine check light on, too. And car was driveable with auto start/stop and remote start unavailable. I went to dealships 3 times. First dealship can't not locate the problem and just reset computer. Second dealship found one problem and replaced a part. But after a couple thousands of miles, the problem happened again. I have two videos, but they are too big to upload.
