Fuel/propulsion system

32 reports
“Vehicle: 2018 Alfa Romeo Giulia, VIN [XXX] Recall: NHTSA 25V-586 (FCA/Stellantis Recall 93C): Fuel Delivery Module / fuel pump I received FCA's safety recall notice for recall 93C. It states the fuel pump can fail and cause a loss of drive power, which can cause a crash without warning. The notice tells me to schedule the free repair with an authorized Alfa Romeo dealer, but the remedy is not available to me in practice. I contacted every authorized dealer in my area, all 1.5 to 2+ hours from my home: •Livermore Alfa Romeo, Livermore, CA: 21 customers ahead of me, no date given. •Alfa Romeo of San Jose, San Jose, CA: 12 customers ahead, about a 4-month wait. •Alfa Romeo of Marin, San Rafael, CA: no parts available. I contacted Alfa Romeo Premium Care (case number [XXX]), and they referred me back to the dealers. FCA has offered no interim fix, no loaner or rental, and no firm repair date. I have to keep driving a vehicle with an acknowledged loss-of-power defect for up to 4 months. I am asking NHTSA to review whether FCA is supplying enough remedy parts and dealer capacity for recall 25V-586, and whether owners facing long delays should be given alternate transportation.”

“The contact owns a 2018 Alfa Romeo Giulia. The contact received notification of NHTSA Campaign Number: 25V586000 (Fuel System, Gasoline). The contact stated that while driving at various speeds on approximately five occasions, the vehicle went into LIMP Mode, lost motive power, and stalled on some occasions. The check engine warning light and the Electronic Throttle Control (ETC) warning light were illuminated twice. The contact stated that while attempting to accelerate, the vehicle failed to accelerate above 30 MPH. The vehicle was taken to an independent mechanic, where it was diagnosed and determined to have a Co pump module failure because the pressure was too high and the Co pump module needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 100,100.”

Electrical system

20 reports1 crash2 related recalls
“On October 13, 2026, while driving my 2018 Alfa Romeo Giulia Ti home from work at night in dry weather, the vehicle’s lights began flickering and then the headlights went out while the vehicle was moving. I suddenly could not see the road and nearly had an accident. The problem is intermittent, and the lights later resumed operating, but the vehicle is unsafe to drive at night. This vehicle has a history of electrical problems involving flickering lights and loss of power. Alfa Romeo and FIAT of Maple Shade previously replaced the Body Control Module (BCM) for the same original problem, but the problem continued. The dealership later kept the vehicle for more than one month. Repair Order 032539 states that the vehicle had been towed in with “no power” and “electrical issues” and that multiple communication codes between modules were found for low voltage. The dealership replaced an aftermarket battery with an OEM Alfa Romeo battery and performed a proxy alignment, but the electrical and lighting problem has returned. The dealership also advised me that water had been entering around the windshield and affecting the vehicle’s electrical system. The windshield…”

Power train

8 reports
“i have been waiting for months received a letter from Alfa Romeo sent them my details, for them to get in touch with me when the remedy for this potential dangerous fault to be rectified. Many crashes have taken place, as the car could potentially cut out whilst on the highways. For Alfa Romeo to leave me in a state where this car could cut out without warning at any stage is not unacceptable. I have to use my car for work, and I am having to resort to using other means with the fear this car could cut out on me on the freeways. They have failed to respond to my email or have they sent me a followup letter to get my car booked in and fixed.”
