2019 Alfa Romeo Giulia: check engine light

Filed Aug 27, 2026 · Fuel system · AZ

1. The fuel delivery/fuel pressure system is malfunctioning. The vehicle has experienced fuel-pressure related diagnostic trouble codes, loss of power, stalling, and limp mode. The fuel pressure sensor was replaced, but the same diagnostic codes and symptoms continued. The symptoms are consistent with the fuel delivery module/fuel pump defect described in the federal safety agency recall 25V586. The vehicle and affected components are available for inspection upon request. 2. The vehicle repeatedly enters limp mode and has experienced loss of power, stalling, and severe shifting problems, especially with low fuel. I have had to drive 20–30 miles on the freeway while unable to accelerate or shift normally, nearly causing multiple accidents around traffic and semi-trucks. I regularly transport my family and children, greatly increasing the safety risk from an unexpected loss of power or stalling. 3. No. The problem has not been reproduced or confirmed by a dealer or independent service center. However, the vehicle has experienced repeated loss of power, stalling, limp mode, and shifting problems, along with the same two fuel-pressure related diagnostic trouble codes. The fuel pressure sensor was replaced, but the codes and symptoms remained. 4. No. The vehicle has not been inspected by the manufacturer, police, or an insurance representative. 5. Yes. The check-engine light appeared with codes P018D and P018B. The vehicle subsequently experienced limp mode, loss of power, stalling, and severe shifting issues, especially with low fuel. Replacing the fuel pressure sensor did not resolve the codes or symptoms.

Twice now, my 2019 Giulia, which only has 27,100 miles, has flashed a check engine light and a "flash/lighting" symbol while driving at highway speeds. When this happened, the vehicle's throttle became unresponsive. This resulted in a sudden power loss--the accelerator would not respond to input, which creates a huge safety issue. I had it towed as I did not want to cause an accident. My trusted mechanic ran the diagnostic code (P008a) which indicated low pressure from the fuel pump. This is addressed in recall numbers 93C (Manufacturer) and 25V‑586 (the federal safety agency). However, the federal safety agency does not show any active recalls for my vehicle VIN. My local dealership indicated this is because Alfa Romeo has not distributed the correct parts to the dealerships. Alfa Romeo customer service said this is incorrect. I am stuck with an unsafe and unreliable vehicle due to the precise recall item that Alfa Romeo says does not apply to my vehicle.
