Owner report 11704490 · 2025-12-11 (December 11, 2025)
I was traveling along the San Francisco Oakland Bay Bridge on a normal commute day when the brakes started sticking early on after that point, by the time I reached the Caldecott tunnel after the incident on the Bay Bridge, the brakes locked up completely, forcing me to coast without using any brakes and subsequently the brakes started smoking. I had to exit the nearest exit to stop the car and tun it off. I had to have my car towed to the repair shop the following day. My car is now unusable for the past two weeks until I can get a resolution…

Owner report 11567541 · 2024-01-24 (January 24, 2024)
Around January 30, 2023 (need to verify the exact date). My vehicle went on limp mode, the engine light went on plus an additional warning light. I was driving on highway 99 when my car started to stall. It felt like the car put itself in neutral mode. It was frightening as it happens randomly & suddenly after being able to drive 60+ mph. It wouldn’t pick up speed. Driving 5 mph. It was frightening as I was far from the exit & the vehicles behind were honking and 1 swerved, thankfully the driver was able to change lanes. I tried my best to move…

Owner report 11667062 · 2025-06-16 (June 16, 2025)
Let me start by stating that this incident is just one of many occurrences that has happened to me with this vehicle. I was driving down a straight highway that was pretty heavily congested with traffic of other vehicles, when all of a sudden I felt a loss of power with the vehicle and some error codes came up on the dashboard indicating the engine needed to be serviced, start & stop was unavailable, and to service electronic throttle control. I also noticed that the vehicle driving mode had switched by itself from Dynamic to Natural mode. Aft…

Owner report 11758666 · 2026-08-21 (August 21, 2026)
My fuel pump started to fail. I am open to having it inspected, the problem is I already replaced it myself because I wasn’t aware of the fuel pump recall for the 2017-2019 models. I know my vehicle is a 2020 but it was manufactured in 2019. It happened twice, I was driving on the highway when my car suddenly lost power. I couldn’t accelerate and I had to merge through multiple lanes to try and pull over safely. I took it to the Alfa Romeo dealership and they were the ones to tell me my fuel pump was failing. No warning lamps, or messages, …
