What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2021 Alfa Romeo Giulia, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

Each component in detail
What the reports in each category say, in the owners' own words
Electrical
Reports naming the electrical system — wiring, battery, charging, control modules, infotainment and electrical accessories.
From owner reports, verbatim
fuel line and fuel pump and module replacement.
In Feb 2025, I was involved in an accident where a driver damaged my driver's side door. I brought my car to the Fix Auto Downtown LA location for repairs. Cosmetically the door was repaired, but over the next year my latch would temporarily lock, preventing access and requiring me to enter through my passenger side door/climb over the center console. In Feb 2026, the latch permanently closed. In Jan 2026, I hit debris on the freeway, which required a repair of my front bumper and undercarriage. I had moved from LA to Orange County, and went to the Fix Auto Yorba Linda location to remediate the door repair and address the new damage. The date of repair for both items was April 15, 2026, as I was unable to make time for an immediate appointment. I received the car back on May 5, 2026, and noticed the front collision error light was turned on, the parking collision mode worked only intermittently, and I had difficulty one time the next day with my door opening (was stuck partially latched/open and my gas cap would not open). The door and gas cap worked after the incident, but, due to both repair shops' lack of quality work, I'm skeptical that the initial problem was remediated. I would like to request both the Fix Auto Downtown Los Angeles and Yorba Linda locations be investigated for returning my vehicle in an unsafe condition. The repetition in the state of repairs indicates potential negligence from Fix Auto.
