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 the federal safety agency 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 the federal safety agency investigate this issue further and require the manufacturer to provide an immediate and effective remedy. Owners should not be placed in a position where they must operate an unsafe vehicle while waiting for a repair solution. Thank you for your attention to this matter.

It's well known by Alfa Romeo/Chrystler, Stelvio owners and certified Alfa Romeo mechanics that the O-ring in the oil send/receive/turbo lines is faulty. Spewing oil into the engine compartment and engine components and accessories i.e., belts, brake components creating a major liability for Alfa Romeo. The smoke from burning oil is overwhelming and visible inside the cabin throughout the interior of this car. THIS IS A MAJOR SAFETY HAZARD TO ALL ALFA ROMEO STELVIO OWNERS WITH THE 2018 MODEL.

My 2018 Alfa Romeo Stelvio experienced a complete electrical failure and will not start at all. The vehicle suddenly lost all functionality and remains fully inoperable. The dealership has had the vehicle for an extended period and has been unable to diagnose or repair the defect. This appears to be related to known electrical issues in 2018 Stelvio models, including BCM (Body Control Module) failures, wiring faults, and fuel system defects reported in recalls and TSBs. A no-start electrical failure is a serious safety concern because similar defects in this model have been linked to unexpected engine shut-offs. The vehicle has been out of service for over 30 days. This is a major safety and reliability issue. I am requesting that the federal safety agency review this defect, because the manufacturer has not provided a resolution.

I’m having fuel pump issues which it came to my knowledge there was a recall with no remedy

Filed Sep 24, 2025 · Electrical, Engine · MD

1. What component or system failed or malfunctioned, and is it available for inspection upon request? The low-pressure fuel pump (fuel delivery module) appears to be failing, consistent with Recall 25V‑586 / Alfa Romeo Campaign 93C. This causes fuel starvation and loss of motive power. 2. How was your safety or the safety of others put at risk? The vehicle has experienced loss of motive power (LOMP) while driving. At times it jerks or hesitates when accelerating from a stop, and while climbing a hill it suddenly lost power, displayed a Service Electronic Throttle warning, and went into limp mode. This created a risk of being unable to accelerate safely in traffic, increasing the chance of being rear-ended or unable to merge. 3. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. I described the symptoms to Alfa Romeo Service dept, and they told me it is related to the recall and that other customers have reported the same symptoms and warning lights. However, they advised that there is currently no remedy available, and I must wait for the fix before scheduling an appointment. 4. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Not yet. Alfa Romeo advised that no remedy is available at this time, so the vehicle has not been formally inspected by the dealer or manufacturer. Advised not to drive long distances until fix determined. 5. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? Yes. Check Engine Light and Service Electronic Throttle came on as car lost power and entered limp mode with code P0299. Alfa Romeo Service Dept tech said these warnings match the recall. Rep said this shows how loss of motive power from fuel starvation manifests electronically & ECU interprets fuel starvation as underboost, which then triggers limp mode.

Description of the Problem: While operating the vehicle, multiple warning lights illuminated including the Electronic Stability Control (ESC) warning light, the check engine light, and other unknown warning indicators. In addition, several warning messages were displayed, including “Service Engine Soon” and other unknown messages. When this occurs, the vehicle begins to overheat, the auto start/stop function becomes disabled, and the vehicle loses power and will not accelerate as expected. Component or System Failed / Malfunctioned: The exact component is unknown at this time. The failure appears to be related to the engine, powertrain, or electronic control systems. The vehicle and components are available for inspection upon request. Safety Risk: The vehicle’s failure to accelerate and overheating while in motion creates a serious safety hazard. This puts the driver and passengers at risk, especially if the loss of acceleration occurs in high-speed traffic, intersections, or on highways. Reproduction of the Problem: The issue has recurred multiple times. It has not yet been officially reproduced or confirmed by a dealer or independent service center. Inspections: At this time, the vehicle has not been formally inspected by the manufacturer, police, or insurance representatives. Warning Lamps, Messages, and Symptoms Prior to Failure: The problem is preceded by the illumination of the ESC light, the check engine light, and other unknown warning lights. The messages “Service Engine Soon” and others appear immediately prior to or during the failure. These warnings occur before the loss of acceleration and overheating. Additional Notes: The failures are ongoing and have occurred more than once, raising concerns about reliability and safety.

I had my radiator fail, lost all fluid and had to be towed. The car has 73,000 miles on it, is well maintained and garage kept. Alfa has sent the dealerships a Service Bulletin item about the issue, but never contacted the consumers about fixing it proactively. My son broke down on a highway, was able to limp the vehicle to a parking lot where the car had to be towed. The repair was done by Alfa and cost almost $3,000 No issues showed up prior.

The car never showed signs of an issue, I got on the car with my two children, when I attempted to start the car. The engine started smoking and smelled like burned plastic. We got out of the car, the smoke went on for about 15-30 seconds. After that the car did not start. The engine's wiring was charred. I was informed by the dealer a ground strap failed. This ground strap is exposed to the elements at the bottom of the engine and it's prone to corrode, rendering it useless and causing the electrical wiring to overheat and potentially start a fire.

My 2018 Alfa Romeo Stelvio was diagnosed by a certified Alfa Romeo dealer with a major engine defect involving coolant mixing with oil. The diagnosis revealed internal failure likely stemming from the oil cooler or head gasket, and the parts estimate alone was over $17,000 — not including labor. The dealer confirmed the issue but stated no recalls apply and denied warranty coverage. The car showed early signs like minor overheating and coolant loss, but no clear warning lamps or check engine lights until the issue escalated. This defect significantly increases the risk of engine failure, overheating, or loss of power while driving — posing a serious safety concern. I have since discovered multiple other owners reporting the exact same problem in Alfa Romeo forums and consumer complaint sites. The dealer has confirmed the issue but refused support. I believe this may reflect a broader design flaw affecting many vehicles and should be investigated for potential recall.

The engine has shut down in traffic on the following occasions: 1) July 2023 in The Woodlands, Texas. 2) Later that same day on [XXX] in Plantersville, Texas. 3) In August 2024, on [XXX] and 4) on [XXX] . My vehicle is available to the federal safety agency upon request. On each occasion, except one, I was fortunate to be in the right hand lane and was able to pull over onto the shoulder before any could hit me. On [XXX] , near Richards, there was no shoulder and I was stopped within the single lane of westbound traffic. I was fortunate that traffic was light at that time and that it was daylight. After the first two incidents in 2023, I took it to Northside Imports in Spring, Texas (XXX) They were unable to duplicate the problem or determine what was the cause. On [XXX], I took the car back to Northside Imports and they determined that it needed a new fuel pump, seal and control module. (I was informed on Friday, [XXX] that the parts have been received and can be installed on [XXX].) Between the time that the fault was identified and the time the parts were available the car has failed on the highway twice, once on [XXX] and once on [XXX] . The vehicle has not been inspected by anyone but Northside Imports in Spring, Texas. There were no warnings in advance of the shutdown. I was able to restart the vehicle after a short period of time after disconnecting the battery. Each time, it restarted in "limp" mode.

I was in the process of merging on the the express way when my vehicle threw a warning light, "service electronic throttle control" along with a "service engine" message and a check engine light. The vehicle went into a "limp" and had extremely poor acceleration, I was almost rear ended because the vehicle couldn't reach highways speeds fast enough. The vehicle has not yet been inspected my the manufacturer but I did some research on this issue and found it to be alarmingly common. There seems to be no clear answer to the reason for this and no sure repairs for the problem. This poses a safety risk to drivers as this problem seems to happen while accelerating. It can be dangerous if someone on the expressway is attempting to merge into 60mph traffic and hit "limp mode" at roughly 30. I believe an investigation need to be conducted regarding this followed by a recall of the affected part.

I have had several incidents with my Alfa Romero Stelvio losing power while driving, This problem has been going on for quite some time, i have had several parts changed out with the same results a few weeks or months later. I took the vehicle to Jim Ellis Alfa Romero for repairs and told them the vehicle was losing power while driving and was told that this problem has occurred on several Stelvios. I left my car with Jim Ellis and a few days later I was told all was good. I didn’t even get a mile away before I loss power again. I brought it back to Jim Ellis and left it again and a few hours later they called and said that the Stelvio needed a new turbocharger that would be $4000 plus installation fees. How is this possible if you told me you had taken care of the issue, and the car didn't even make it a mile.

Please see the following reoccurring problems with the 2018 Alfa Romeo Stelvio, Auto on/off failure has failed 3 times resulting in the check engine light coming on and the vehicle citing service engine. Additionally, the DNA selector doesn’t work when this occurs. The vehicle has been inspected by Southern Alfa Romeo of Norfolk. However, the system reset itself before they inspected. As such they found no evidence of failure. However, within a week the system is back in fault mode rendering the vehicle unsafe to drive. I’ve noticed on several blogs that others owners are having the same problems with no relief from their service provider. Request a the federal safety agency review of this problem with a solution for correction. Thank you!!!

While I was driving the car suddenly stopped sending gas when pressing the gas pedal and put the can a neutral mode. This was the second time this happened. Luckily the first time I was in my neighborhood going slow. The second time was in the middle of the night pitch black on a busy road. I was stranding the middle of the road and almost got hit. I was so fortunate a cop was driving by an helped. This has been extremely unsettling as I have a 1 year old. Luckily he was in the car but I can’t imagine if I was driving with him on a highway. The first time this happened I went to the gas station to fill a gas station to fill up a gas tank and added it my car. The car said I had a quarter tank when it stalled, but when I added the gas I was nearly empty. I was able to drive it to Alfa and they said I didn’t need a need a new fuel pump but don’t run it under 1/4 tank. I bought the car with 30k miles and apparently the fuel pump was already replaced under warranty. The second time this happened was in Dec 2023 and my car won’t get looked at until Jan 30th, 2024. I read up and there are other complaints of the same issue. This has to be corrected or someone will secretly injured. I’m scared to drive the car and will ultimately sell it because it is NOT safe.

Was driving home with my fourteen year old daughter and started to smell a burning smell and began to lose power in the vehicle. Warning light came on that oil level was low. Pulled over as safely as I could on a busy four lane road and opened the hood and saw engine oil and coolant mixed and sprayed all over the engine. Car had never leaked any type of fluids prior to this incident. Had the car towed to one repair shop and was told it would need a new engine. Had it towed to an Alfa Romeo dealer two hours away and was told it needed a new engine too. Initial quote from dealer for a new engine and labor was $22,000. This car is barely worth $20,000. Third party warranty (I bought car used from a dealer) will only pay for gaskets. After weeks of warranty company asking for tear downs of engine and other things, price has risen to $35,000! While reasearching engine malfunctions on Alfa Romeo Stelvios, I have come across many people with similar sitations as mine. Engine replacements at 30,000, 40,000, 50,000 miles. My car has 39,000 miles. This should never happen to car with such low mileage. Called Alfa Romeo customer care and was told that previous owner was not compliant with maintenance and warranty was voided. How do they know that for sure? Just because you don't get your vehicle serviced at the dealership, your noncompliant? I believe that this needs to be looked at from a safety perspective that Alfa Romeo is not doing. During loss of power on busy road and only being able to go 10 mph, we could have easily been rear ended. This total abuse of negligence from Alfa Romeo to recall these engines and fix them, to the warranty company not paying for the engine replacement/repairs, and to the dealer that is charging this extreme amount of money for this. Car insurance will not pay for this as this is mechanical and was not involved in a collision.

The car will shut off in traffic out of no where. While driving the cars speed randomly will decrease to 15 miles and hour on the interstate almost causing a crash. When the cars speeds decreases randomly it does not all you to accelerate. Therefore the car is just going 15 miles an hour on a highway of no less than 65 miles. This has happened multiple times in the last 2 months. I see there was a recall of the same vehicles for the same issue a few years ago but this vehicle wasn’t listed yet it is experiencing the same issues.

I orchard my car used, but still under warranty. Within a week it has shut down with a service engine error. I was told it was the power control module (PCM) both times. There's no logical reason, I know of for a car with only 40K miles on it to have an engine failure such as the PCM. Both times both dealerships stated that the game was coming from the solenoids and having a misfire caused by the PCM.

Alfa romeo USA is in my opinion hiding a constant problem they have with stelvios. The oil turbo line has a faulty oring and leaks oil onto engine which causes smoke that can not be healthy to breathe in. I have talked to severa alfa dealers in service depts and they confirm to me that they have fixed numerous stelvios with this problem. This should be a national recall for repair at no cost to the consumer. I tusually happens close to warranties expiration near 50k miles or shortly after.

There was a issue with my vehicle turning on fine then once I got down the road it started to not go it completely stopped in mid drive on me and the engine light and oil light going crazy. It started sounding bad this has happened 3 times it shouldn't be happening on a 2018 that's been up to date on maintenance. I take the care home park it for a day then never day crank it up it cranks right up as if it did nothing the day before sounds normal runs fine no lights on at all but it did this 3 times in 3 months. Something is definitely malfunctioning. I also got in a alfa romeo group and 75 percent of the people has had the same issue with their vehicle rather it be the car or SUV or year they all had the same engine type.
