Upon depression of the brake pedal, the brake pedal depressed to the floorboard, and the braking system failed to operate as needed.

Upon exiting the vehicle, the contact saw brake fluid leaking underneath the passenger's side of the vehicle. Due to the failure, the vehicle was towed to the dealer; the contact was informed that the hydraulic braking system had failed and needed to be 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 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. …
NHTSA #25V-586 Recall #93C 2017-2019 ALFA ROMEO GIULIA, 2018-2019 ALFA ROMEO The vehicle has been experiencing inconsistent fuel readings, an electronic throttle control fault, and a service engine warning. When the electronic throttle control fault occurs, the vehicle loses power, stalls, and struggles to accelerate, which raises concerns about its suitability for commuting. On several occasions, while driving on highways, my vehicle has experienced loss of power, resulting in a significant reduction in speed. This has necessitated extended commute times on streets due to the apprehension of causing accidents. Consequently, I have had to miss several workdays in an attempt to address this issue. Initially, I resorted to using rental vehicles out of pocket until a solution for this recall was found. …
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. …
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. …
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.
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.
