NHTSA complaint #11429152, filed 2021-08

“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. …”

NHTSA complaint #11667062, filed 2025-06

“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, just suddenly losing power while driving. …”

NHTSA complaint #11758666, filed 2026-08

“Just bought a 2020 Alfa Romeo Giulia from Carvana and two days later while driving the check engine light came on along with the electronic throttle light and the auto start/stop light. While driving the vehicle went into complete limp mode in a busy intersection and I had to pull off quickly to avoid being hit by other traffic. Engine codes came up fuel pressure related.”
