Alfa Romeo Giulia won't shift problems

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.

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.

The vehicle is experiencing multiple system malfunctions involving the engine performance, fuel system, and electronic throttle control, including engine shaking while idling, activation of the check engine light, a “start/stop unavailable” message, limp mode (inability to switch between driving modes), and illumination of the electronic throttle control warning light. One dealership suggested the issue may be related to an open fuel pump recall after noting that previously replaced spark plugs were heavily carbon-fouled, indicating excessive fuel combustion; however, another dealership diagnosed the engine as “scored” and recommended major repair. This diagnosis is disputed, as an independent mechanic performed a borescope inspection and reported no visible internal engine damage. The issue is intermittent—some days the vehicle operates normally, while other days it becomes undrivable. This creates a safety risk, as the vehicle may unexpectedly enter limp mode, limiting acceleration and drivability in situations such as merging or navigating traffic. I have not been involved in any accidents related to this issue and avoid driving the vehicle when symptoms are present. The vehicle has been inspected by both a dealership and an independent mechanic, but not by police or insurance representatives. Warning lights and symptoms, including the check engine light, electronic throttle control light, and start/stop warning, began appearing prior to the drivability failure and around the same time I received notice of the fuel pump recall. The vehicle is available for inspection upon request.

Car suddenly got p018c & p018b codes along with (setc) notification while on freeway and continuously would go in and out of limp mode when accelerating or breaking which nearly caused me to crash. when arriving home I check my fuel pump relay and it looked burnt or overheated, I tried replacing sensors as well as relays but the problem remains whenever accelerating or breaking at low speed now, just without the check engine light.

I am filing a complaint in regard to recall 93c for my 2017 Alfa Romeo. The dealership/manufacturer has failed to provide me with a fix, parts or even just a loaner car due to the safety hazard. My car has gone limp mode several times on the highway at speeds of 70mph. This is unacceptable.

While driving my Alfa Romeo, the vehicle experienced a significant malfunction involving the engine and power-train system. The vehicle will not accelerate properly and repeatedly goes into limp mode, resulting in a sudden and severe loss of power, especially while driving on the highway. The engine warning light is illuminated, and the vehicle hesitates, jerks, and fails to respond. This malfunction created a direct safety risk to me and other drivers on the road. The loss of acceleration occurred while traveling at highway speeds, making it difficult to merge, maintain traffic flow, or avoid surrounding vehicles. The problem has been reproduced multiple times, and the vehicle consistently enters limp mode when attempting to accelerate. The issue has been observed during normal driving conditions and does not appear to be a one-time event. The vehicle and its components are available for inspection by the manufacturer, dealer, insurance representative, or any required agency. At this time, the vehicle has not yet been formally inspected by the manufacturer, police, or insurance company, but I am prepared to provide access for evaluation. No warning lights and symptoms prior to the complete failure.
