This is a follow up for complaint #11693742 issued on October 16, 2025. I picked up my car from the dealership (Jim Ellis Alfa Romeo Atlanta) after the nearly $5k repair that they stated was due to an Oil Pump failure not the Fuel Pump failure as indicated by the Stellantis Recall, only to find that they falsified information on the paperwork description. They left out the information that I gave them when I told them that the dashboard displayed the following warning lights: ETC, Auto Start-Stop Unavailable, and Check Engine. They wrote only the Check Engine light was reported. They falsely stated that only the Check Engine light was illuminated, when in reality all three of the aforementioned warning lights were displayed the very morning that I had the car loaded on the tow truck. Please investigate Stellantis/Alfa Romeo for possibly misleading and falsifying information in order to have consumers foot the bill for repair for a fix for power loss due to a Fuel Pump failure when in actually it is an Oil Pump failure, or an Oil Pump failure that they are falsely claiming a Fuel Pump issue. This repair cost me about as much as the cost of a used 2018 Alfa Romeo, and the company is making enough money of this repair such that when they do honor the recall repair, then it won't cost them anything. It seems easy to me that if they is a Fuel Pump failure that is resulting in a recall, then the easy fix (that Stellantis should cover the cost) is to replace the fuel pump.
On multiple occasions over last 3 years, vehicle has lost power while driving. Each repair service has credited it to batteries needing replacement and losing power. Have replaced batteries and kept them plugged in when car is parked at home. No longer driving car as it is not safe.
While driving 15-20mph, warning lights: Check Engine, Auto Start-Stop Unavailable, and ETC, all began to sequentially cycle. The car's ability to accelerate significantly decreased, even achieving 30-40mph was laborious. Once on the highway, the car was significantly slower and the power was obvious. The car took a long time to reach 55mph and was going over that speed. I had the car towed to dealership the next day, for I was afraid that it was the fuel pump failure and felt the car wouldn't make the 75mi drive. After a few days, the dealership said that the ETC Code wasn't the fuel pump, but the oil pump causing the power loss. They said that Alfa Romeo had many models have oil pump failures, and it requires engine tear down to replace the oil pump and cost about $5000. Alfa Romeo Customer Care stated there is no recall for this problem, so one has to pay the $5k for the repair. I think Alfa Romeo knows the true cause of the power loss problem and the remedy, and using the oil pump as a loophole to make the consumer pay for a problem that they should cover the cost of repair. My car is at Jim Ellis Alfa Romeo in Atlanta, Georgia.
There were several code error messages describing a fuel pump issue that also creates other engine components to fail. For my concern of the safety my life, I paid to tow my vehicle directly to the car dealership service department to be inspected and am currently waiting to be contacted of their findings. In order to be able to move my car from blocking traffic and out of harm's way, the error codes had to be erased. I took pictures of the error codes prior to erasing and provided them to the service department for their review. Warning lamps and messages flashed simultaneously when my vehicle ceased to function. While driving my 2018 Alfa Romeo Giulia Quadrifoglio September 16, 2025, the engine ceased to function under legal normal driving conditions for no apparent reason. The engine immediately turned itself off, and both the steering wheel and vehicle was locked in place (unable to move). This event jeopardized me, and other affected drivers' lives. It was only due to the quick reaction of defensive driving attentiveness that prevented the potential collision of multiple vehicles including loss of life/lives. I had taken my vehicle to the same service department previously in November 2024 for the exact same type of issue (ceased vehicle, locked in place steering wheel and vehicle). However, because error messages were erased, the service department would not be able to know what steps were needed to fix the problem and that I should bring back my vehicle with error codes intact should this occur again. I have this in writing on my invoice. No police report involved as no physical accident/damage occurred, and everyone who was involved including myself left without further incident, and very traumatized.
UNKNOWN, driving down a busy road and check engine light popped up and service electronic throttle system as well car stalled in the middle of the road and would not start when I tried to it would crank but not start. I noticed this incident was occurring in the past when I was close to half a tank of gas but now it’s occurring when I’m at 3/4 tank. I already addressed the possible issue of being a weak battery as I had to spend $250 on a new battery and the next day it happened again. After going through the forums and speaking with dealers they all have the same diagnosis that the fuel pump is going out. I would buy a fuel pump and replace it myself but you have to replace the module with it and have to have a very expensive scanner to sync the two together.
The contact owns a 2018 Alfa Romeo Giulia. The contact stated while driving at an undisclosed speed, the vehicle stalled with the check engine warning light illuminated. The vehicle was taken to an independent mechanic where it was diagnosed that the fuel pump module had failed and needed to be replaced. The vehicle was not repaired. The dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 50,000.
Mileage: 50,000
Fuel pump issues have caused my car to create unsafe driving. My etc system kicks on and off while driving which causes massive loss of power then accelerates to the point of red line. it's like I'm putting my pedal to the floor in traffic when trying to inch up. Fuel lump is on order for me but has been on back order for more than 3 months with no date of shipment. Dealership said car was OK to drive but could ultimately cut off and not start back up till this part is replaced.
My fuel pump has been failing multiple times over the last 4 months. It has left me stranded in the middle of intersections, freeways, and highways on multiple occasions that has cause back up traffic and areas of the road completely closed until I can move my car. I have had this car diagnosed twice with a certified mechanic shop and a master tech with these issues and it is confirmed both times that I need a new fuel pump. When contacted Alfa Romeo/ Mike Ward dealership for review, diagnostic scans, and part replacement they told me it could be a couple of weeks until my car can even be looked at. Both my shop and the dealership have told me that this part is on back order with no ETA and no possible way of getting that part so my car can be functional. These issues first appeared when I would accelerate from a complete stop and it would take a few seconds for my car to begin moving. This slowly progressed into my check engine light, auto start/ stop error light, electric throttle error light, and front crash detection light have all turned on and remained on for about 2 months until the car began dying in the middle of the street. This had come to be so servers that the car is now no longer drivable and each time it is driven it dies within a few minutes of driving.Again since there is no ETA there is no way for me to fix my car, this is my only mode of transportation and it has left me ain multiple dangerous situations and now with no transportation now that Alfa Romeo is refusing to make the parts needed for repair.
Service Engine" and "Service Electronic Throttle" lights came on. The car/engine started shaking/stuttering pretty violently, so I quickly turned off the car. I waited about 2 minutes and started the car again, and same thing. I waited another 10-15 minutes to start the car again. This time, the car started fine without "Service Electronic Throttle" light, but "Service Engine" light was still on and the drive mode was stuck on N
While driving on highway the Check Engine light illuminated along with a Service Electronic Throttle warning. Soon after engine died and the vehicle coasted to the side of the road. I was unable to restart. After tow to dealer vehicle would not start, awaiting dealer diagnosis. No safety issues were encountered with this incident.
When driving on a road, with speeds around 30mph, the car was failing to accelerate. The car had a warning "service electric throttle control". The car proceeded to have engine failure and stall at lower speeds when coming to a stop sign & when coming to a red light. This was a safety hazard, car turned off and was put in neutral when it should have stayed in drive. Other cars present on the road around, car could not accelerate in a busy intersection and was stalling in traffic.
The Electronic Throttle control and check engine lights came on suddenly, and then the car lost power. It would not turn off or turn on. The gear shifter did not work. It just stalled. Could not engage or disengage emergency brake. Steering wheel locked. I got it towed to Alfa Romeo of Glendale and they told me the fault was with a faulty fuel pressure sensor, which they replaced, telling me if the error recurred they would need to replace the fuel tank. The safety of everyone was put at risk because the car abruptly lost power and could not be moved off the road.
Fuel pump seems to go out intermittently. I get the electronic throttle control warning light and auto start not available warning light and then the car cannot be turned back on. After towing it home and letting it sit for a couple of days it will start again. It shut down once on a highway entrance ramp and I had to quickly pull over to avoid getting hit. Has occured 3 times since I bought it three years ago. A dealer did read the code for fuel pump. Could not reproduce at the service center. Car has not been inspected by manufacturer or police. Warning lights and messages do appear and the car does not accelerate properly and sometimes turns off.
Head Gasket blew/failed well before it should have. This caused oil to leak under the car and in the entire engine, creating a safety hazard and environmental hazards. Engine is subject to overheating. (Engine needs full replacement due to this faulty equipment).
While driving on the interstate, the car triggered a check engine light, reported that start/stop was unavailable, and ETC throttle needed servicing. Error codes report a turbocharger underboost. This is a known issue experienced by Alfa Romeo Giulia owners involving the turbo wastegate actuator. The actuator arm gets worn at the linkage to the wastegate, introducing play and reducing turbo pressure. There was no prior warning that this would happen, dealer did not confirm this issue until the second time the car was serviced for this issue, and the only stated solution is to pay for and replace the entire turbocharger.
My son was driving the vehicle on I75 at 68-70 MPH yesterday around 5:45 pM. The car started stalling.I was driving my other vehicle Volvo XC 90 right behind. I noticed his vehicle slowed downs drastically and within 4 seconds he was on left shoulder and stalled completely and would not stop. The vehicle went from 70-40-20-0 all in 4 seconds. Something very similar happened back in May of 2022. The Alfa Romeo dealer replaced the fuel pump in September/October of 2022. Stalling happened again yesterday. This is a very dangerous and known issue and Alfa Romeo manufacturer is not doing any recall or addressing this issue. Yesterday’s incident would have custard an accident which would have lead to injuries or even worse fatality When I called Alfa Romeo manufacturer’s customer service all they had to say was that the vehicle is not under warranty and they won’t cover the repairs. Please do a major recall on Alfa Romeo vehicles and make the manufacturers be responsible for the issue and make them to do a recall & repair. This is a very serious issue with Alfa Romeo cars. Stalls in the middle of the road.
When driving on the I-10 the ATV light came on the christmas tree lights cycled and the car rapidly came to a stop and shut off.
Vehicle presenting significant life-threatening system-wide failures while driving. These catastrophic system failures result in the vehicle becoming immediately undrivable without warning placing passengers at significant risk, particularly when traveling at high speeds (e.g., interstates). The following summarizes system-wide failures in the 2018 Giulia and failed attempts to correct this defect by Alfa Romeo and dealer: •11/30/20: One (1) day of service after complete multi-system failure while driving locally. Returned same day by service department but failed to repair (see following service report). •11/30/20 – 12/4/20: Five (5) days of service. Vehicle presented to dealer service department immediately after pick-up from aforementioned service to correct 2nd systemic failure which subsequently occurred promptly after departing the dealership. Resulting system failure produced highly dangerous operating conditions in which vehicle became immediately and unexpectedly incapacitated while attempting to merge into interstate traffic at accelerating speed. •1/25/21 – 2/5/21: Twelve (12) days of service following 3rd system failure. As per dealer service reps, an Alfa Romeo service agent stated there was a defect in in the molds used for creating engine / engine blocks in the Giulia and the resulting defects can cause an oil leak while in operation which, based on its location, can result in entire operating system collapsing unexpectedly when said leak occurs. As documented in the service record, metal shavings were found in the oil and oil pump of vehicle and per the guidance of the Alfa Romeo service agent, dealer replaced the entire engine •12/10/21: On 12/10/21, the 4th catastrophic system failure occurred during interstate travel in the rain while attempting to accelerate and pass a slow moving vehicle. Vehicle became unexpectedly incapacitated causing seriously life-threatening conditions. Vehicle available for inspection currently.
SERVICE ELECTRONIC THROTTLE CONTROL AND CHECK ENGINE WARNING LIGHTS CAME ON. CAR DIED IN THE MIDDLE OF THE ROAD AND TOOK SEVERALLY ATTEMPT TO RESTART CAR. *TR
