Volvo XC90 stalling problems

Filed Sep 23, 2026 · Electrical, Fuel system · PA

Vehicle has exhibited lagging and stalling while driving in "Pure" (electric-only) mode since approximately April 2026, at approximately 85,000 miles, accompanied by an illuminated check engine light. This has occurred repeatedly at red lights, intersections, stop signs, and in stop-and-go traffic, creating a risk of sudden loss of propulsion in live traffic situations, including at intersections where an unexpected stall could result in a collision. The dealership (Volvo Cars of Fort Washington) has diagnosed this as originating from multiple hybrid drivetrain components over several repair visits: the High Voltage Coolant Heater (replaced per a referenced Volvo Technical Service Bulletin), the Inverter Electric Rear Axle Drive Module (IEM) — diagnostic data showed one internal transistor (phase W) reaching 135°C, a severe outlier compared to the other two phases reading approximately 25°C — the A/C refrigerant shutoff valve, and most recently the Electronic Rear Axle Drive (ERAD) transmission, where diagnostic monitoring showed the ERAD clutch slipping during test drives. Volvo's own internal case management system has classified this case as a "Repeat Repair." Despite multiple repair attempts, the underlying drivability defect (lagging/stalling) has recurred each time, including almost immediately after the vehicle was returned following the initial repair, with minimal intervening use. This pattern indicates a persistent, unresolved defect in the vehicle's hybrid drive system that presents a safety risk due to unpredictable loss of power while driving.

The contact owns a 2019 Volvo XC90. The contact stated that while driving at various highway speeds, the vehicle suddenly entered LIMP mode and decelerated before stalling. The failure had occurred on two separate occasions. On one occasion, the vehicle did not restart and was towed to the dealer. During the second occurrence, the vehicle was restarted moments later and was driven to the residence. The vehicle was later towed to the local dealer, where the contact was informed that diagnostic trouble codes for fuel delivery system malfunction and low fuel pressure were retrieved; however, the exact cause of the failure was not determined, and the vehicle was not repaired. The contact stated that the fuel tank was half-full during the failures. The manufacturer was notified of the failure. The failure mileage was 79,900.

The contact owns a 2020 Volvo XC90. The contact stated that while driving 35-40 MPH, the message "Vehicle Not in Park" was displayed intermittently, and the vehicle stalled. The contact was able to pull over to the side of the road. The vehicle was restarted after several attempts and was driven to the residence. The vehicle was then taken to the dealer, where the contact was informed that no failure was found. The vehicle was not diagnosed or repaired. While investigating the failure online, the contact became aware that it was a common failure, and that the dealers were unable to duplicate the failure. The manufacturer was not notified of the failure. The failure mileage was approximately 79,000.

I am reporting a failure of the fuel pump system in my Volvo vehicle, which currently has approximately 60,000 miles. The failed component is available for inspection upon request. The issue was confirmed by an authorized Volvo dealership, which diagnosed the fuel pump as defective and requiring replacement. This appears to be a premature failure given the mileage and proper maintenance of the vehicle. This failure presents a serious safety risk. A faulty fuel pump can cause the vehicle to stall unexpectedly while driving, increasing the risk of a crash, especially at highway speeds or in traffic. Loss of engine power without warning places not only the driver and passengers at risk, but also other motorists on the road. Prior to the failure, the vehicle experienced symptoms consistent with fuel system issues, including difficulty starting and intermittent performance irregularities. These symptoms escalated until the vehicle became unreliable to operate. The problem has been confirmed by the manufacturer’s authorized service center, and the vehicle has been inspected accordingly. No external factors or misuse contributed to this failure. It is my understanding that Volvo has issued recalls and/or acknowledged similar fuel pump defects in other vehicles of comparable models and years. Based on the nature of this failure and its alignment with known issues, I believe this vehicle should be evaluated for inclusion under an existing recall or be subject to further investigation. Given the safety implications of fuel system failures, I respectfully request that this issue be formally reviewed to determine whether a broader defect trend exists that could impact other vehicles. The failure occurred at relatively low mileage and under normal operating conditions, raising concern of a systemic defect rather than normal wear and tear.

The vehicle’s Start/Stop system began displaying warning messages and malfunctioning prior to the expiration of the factory warranty. The issue first appeared before 50,000 miles and reappeared at 49,997 miles, when a warning was displayed on the dashboard. The vehicle was taken to an authorized dealer for inspection. A diagnostic review confirmed the need to replace the Start/Stop auxiliary battery and repair the Park Assist system. A diagnostic fee was charged, and both system failures were documented. The Start/Stop system’s failure raises a potential safety concern because the vehicle may not reliably restart after automatically stopping at intersections or in traffic. This could lead to dangerous situations if the vehicle stalls unexpectedly or fails to re-engage power at a critical moment. Although the issue has not caused a crash or injury, it introduces unpredictable behavior that could compromise safe operation. The Park Assist system also failed, triggering system warnings and disabling parking assistance features. If a driver is relying on these systems during low-speed maneuvers, a sudden or silent failure may increase the risk of collision with objects, pedestrians, or other vehicles. The dealership confirmed the problem through inspection and diagnostic testing. The manufacturer was contacted and declined to cover the repairs under warranty, despite the vehicle being within the mileage limit when the issue was first documented and presented for service.

Vehicle started experiencing stalling and when trying to accelerate it would not pick up on speed, I have been quoted by Volvo that the supercharger is bad on a car that is only 6 years old. That repair for this is $2,000 as the engine valve also has to get cleaned out. The vehicle started having issue with AC after 2 years and now the front evaporator has gone bad and with summer Time is when I realized of this defect. $5,000 repair for the evaporator.

I am reporting multiple critical component failures on my 2017 Volvo XC90, which I believe represent potential design or manufacturing defects related to vehicle safety and reliability. At approximately 93,000 miles, my Volvo XC90 experienced a battery failure, thermostat failure, which did not resolve the vehicle's engine issues. Subsequently, the dealership diagnosed a failed Engine Control Module (ECM), requiring complete replacement at a cost of over $5,000. The ECM is a critical motherboard component responsible for engine control and vehicle safety operations. Its failure risks sudden engine malfunction, stalling, or loss of power while driving, which could cause unsafe conditions. I am concerned that multiple major component failures, especially in a premium brand vehicle under 100,000 miles and less than 10 years old, represent a systemic reliability issue. These failures occurred despite regular maintenance and responsible usage. I respectfully request that the federal safety agency investigate whether similar cases exist for 2016–2018 Volvo XC90 models involving premature ECM or engine cooling, electrical, short circuit system failures. I am available to provide service records and additional documentation as needed.

The instrument panel just stopped working. Our safety and the safety of others was/is put at risk because you are unable to see how fast you are going in the car. It also doesn’t let us know how much gas we have left in the gas tank so if the car just stalled out on a highway, it could cause a major safety issue. This is also where cruise control is run from. It’s also the panel where any and all vehicle warnings would show up so if there’s another issue in the car, we are unable to see it.

Instrument panel shuts down while driving on street. I believe it is the central electronic module that fails. It has happened numerous times and it is unsafe to drive without a speedometer, tachometer, odometer fuel gauge, and temperature gauge. It has now stopped altogether. Gauges just sit there and bounce
