What owners say about the engine

Verbatim from NHTSA complaints, newest first
“I am reporting an authorized manufacturer franchise dealer for actively refusing to remedy a federal safety recall and unlawfully withholding my vehicle. My vehicle is a 2019 Alfa Romeo Stelvio (VIN: [Insert VIN]), which is subject to the active Fuel Pump Safety Recall (NHTSA Campaign 25V586000 / Manufacturer Recall Code 93C). The vehicle has been physically located at Southern Alfa Romeo of Norfolk ([XXX]) for approximately 18 months. The dealership service management has explicitly stated that they will not perform the mandatory safety recall remedy, nor will they release my vehicle to a flatbed towing company, until an unrelated $5,000 civil dispute involving a loaner car is paid out of pocket. By conditioning a federal safety mandate and the physical custody of my vehicle on a separate civil debt, this dealership is violating the National Traffic and Motor Vehicle Safety Act (49 U.S.C. Chapter 301). The 1.5-year delay also completely violates the federal requirement to provide a safety remedy within a reasonable timeframe. I request federal intervention to force compliance.”

“The contact owns a 2018 Alfa Romeo Stelvio. The contact received notification of NHTSA Campaign Number: 25V586000 (FUEL SYSTEM, GASOLINE); however, the part to do the recall repair was not yet available. The contact stated that while driving 45 MPH and merging onto the highway, the vehicle entered Low Power Mode, forcing the contact to pull over to the side of the road. The contact then drove to the residence, where the vehicle was turned off and restarted, and the messages "Service Engine" and "Service Throttle Control" were displayed. The vehicle was taken to the dealer, where the fuel system was bled. The dealer later informed the contact that the high-pressure fuel pump had failed and needed to be replaced. The vehicle was not repaired. The contact stated that the high-pressure fuel pump and the fuel delivery module (FDM) were replaced in July 2025. The contact related the failure to the recall. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the failure, but no assistance was provided. The failure mileage was approximately 62,000.”

“I am writing to formally file a complaint regarding serious engine issues I have experienced with my Alfa Romeo vehicle. The ongoing mechanical problems have created significant inconvenience, financial hardship, and concerns regarding the safety and reliability of the vehicle. Since owning the vehicle, I have experienced persistent engine-related problems including [loss of power/engine stalling/check engine light/oil consumption/rough idling/etc.]. Despite attempts to address the issue through repairs and maintenance, the problem continues to occur. These recurring issues have negatively impacted my ability to reliably use the vehicle for daily transportation. In addition, I am concerned that these issues may reflect a manufacturing defect or unresolved mechanical problem that has not been properly corrected. I have made efforts to have the vehicle inspected and repaired, yet the condition persists, resulting in continued frustration and unexpected expenses. I respectfully request the following: * reimbursement for repair costs related to the engine issue * Documentation regarding any recalls, technical service bulletins, or known engine defects associated…”

“I experienced an unexpected Loss of Motive Power (LOMP) event. Late afternoon traffic was fast, estimate 75-80 MPH. I attempted to change lanes get to the righthand shoulder and was very nearly involved in a high-speed collision with a semi-petroleum tank truck. He applied his brakes to avoid hitting me and started to jackknife, but regained control and continued. The truck missed by inches. At this point I had NO remaining power and was essentially coasting until I managed to cross the remaining two lanes of traffic to the shoulder emergency lane. I reset the error codes and continued home with no further occurrences. The incident produced the following warning lamps: Electronic Throttle Control Failure, Start/Stop System Failure and Check Engine, then a few seconds later the Limp Mode/LOMP event. I carry an OBD Scanning Tool with me to be able to clear the error codes when I encounter them. They are typically a cascading event that can result in LOMP. I have experienced a total of 26 of these error lamp events since 4/19/22 which have resulted in 3 LOMP's. The remaining 23 events I was able to reset before the inevitable LOMP. This is the first LOMP that…”

“November 26th my car went into LOMP mode. But then restored itself. December 3rd my car went into LOMP mode again and had not recovered along with a slew of ALARMS. I have been using uber and rental cars since this issue. Highly likely this is a fuel pump issue but unable to determine as the authorized shop is 2hours away and the car will not make it there. I need a remedy I have been out of a car for months now and the recall has no remedy!”

“Subject: Safety Complaint – Open Recall with No Remedy Available I am filing a safety complaint regarding my vehicle, which currently has an open recall with no available remedy. Manufacturer Recall Number: 93C NHTSA Recall Number: 25V-586 VIN: [XXX] After learning about this recall, I have experienced the exact issues described. When the vehicle is exposed to very hot or very cold temperatures, the Electronic Throttle Control (ETC) warning light illuminates, along with the check engine light and the auto stop-start warning light. When this occurs, the vehicle begins to sputter and loses power. It will not properly a-ccelerate and significantly reduces speed while driving. This creates a serious safety hazard, especially in traffic or at highway speeds. A sudden loss of power or inability to accelerate could easily result in a collision, potentially causing serious injury or death. There is currently no remedy available for this recall, yet the vehicle remains in operation on public roads. I do not feel the vehicle is safe to drive under these conditions. I am requesting that NHTSA investigate this issue further and require the manufacturer to provide an…”
