There are 3 owner-reported fuel system complaints for the 2020 Alfa Romeo Giuliain NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
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.
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. After a few short seconds, I felt the RPMs drop completely to zero and I felt a loss of the power steering as well because the engine had shut down completely in the middle of highway traffic. As I was driving on the left lane of a two lane highway, I had to immediately pull over to the right side shoulder, nearly being hit by vehicles behind me as the Alfa Romeo Giulia stalled and immediately cut my speed. I was parked on the right shoulder of the highway with my hazard lights on and put the vehicle into Park. When I tried to restart the engine, it just cranked over for a long time before finally turning on. The same error codes popped up on the dashboard indicating the problem was still there. I tried to continue driving down the highway but the engine kept on shutting itself off and the issue persisted. Eventually I had to call a local friend who has a trailer to help me tow my vehicle back home. The vehicle, when scanned, released the code P008A which indicates a low pressure fuel system error. I have read that this issue is currently being investigated by the NHTSA and would like to clarify and state that this is indeed a very dangerous safety issue and it should be dealt with accordingly.
