2021 Volvo XC40: sudden loss of power

Filed Jan 2, 2026 · Fuel system · CA

The vehicle experienced a complete loss of propulsion, causing it to freeze and become unable to move. The first occurrence happened during the original factory warranty period and required towing to a dealership, but the root cause was not identified at that time. The same loss-of-propulsion failure has since recurred, rendering the vehicle inoperable. A dealership has now diagnosed a failure of an electric vehicle propulsion/inverter component. The vehicle is currently in the dealership’s possession and available for inspection. Loss of propulsion presents a safety risk, particularly if it occurs while driving or in traffic, as it can result in sudden loss of power and inability to move the vehicle out of hazardous situations. The failure has been confirmed by the servicing dealership. There is also concern that a related cooling system component may be involved, but that has not yet been confirmed, as the primary propulsion failure must be addressed first. As of the date of this complaint, the vehicle remains inoperable and has been at the dealership since mid-November awaiting repair authorization.

An abrupt warning appeared on my vehicle, stating that there was a propulsion system failure. A turtle light then pulled up, warning that the vehicle was slowing down. Confused by these alerts, I pulled into a parking spot to shut the vehicle off and back on. Since the car does not have a power button, I had to step outside and re-enter the vehicle. The warnings immediately reappeared. I attempted to reverse out of the parking spot; the car abruptly braked itself and completely lost power. This all happened quickly. Seconds after the initial warning, the car slowed itself down, and within approximately 1-2 minutes of the initial warning, the vehicle completely lost power and the ability to drive. A tow truck came to pick up the vehicle to take it to the nearest dealership, where it is being looked at. We are incredibly lucky not to have been on the interstate or a shoulder-less stretch of road when this occurred. This would have otherwise been an incredibly dangerous and life-or-death situation—for the driver, the passengers, and anyone who happens to be in their proximity on the road.

On October 12, 2021 the above described car had a catastrophic failure of the power system. All functions ceased and the car was dead towed on a flatbed truck. Because the tow mode could not be engaged due to loss of all power the vehicle was dragged onto the flatbed. The repair indicated the cause was a The Battery Energy Control Module (BECM). This is noted in recall R10078. This car was sent for service in April where a request for a software update was made. At that service, no recall was noted and no update was given for this condition. There has been no attempt to recall this vehicle for this problem and it is not noted as a recall for this vehicle. The failure of the energy module caused a complete loss of all power and an inability to move the car.

The 2021 XC 40 vehicle will periodically not restart - may be something to do with the safety key or some other electrical malfunction. The dashboard shows the battery symbol when the car will not restart as if the vehicle is dead (no electrical connection). Also, when the start button is depressed the dashboard illuminates with the dead battery signal, but otherwise, it seems the button is not connected to the vehicle in that the engine does not respond. Also, we had an issue where the vehicle, while we were beginning to stop at a stop sign, went dead and was not responsive. The “Start/Stop” function, although engaged in the center console, is often not operational and will show in the dashboard that it is not operational, but then, randomly (not consistent with the reasons itemized in the Volvo manual for why the start/stop function may not work), will work on a few stops for that particular drive and then revert back to not being operational on the next trip, although it is engaged to be “on” in the center console. Again, this appears to be a sign or symptom of some sort of electrical malfunction. Now, most recently, my wife and daughter were driving the vehicle, and it lost power and shut off in the middle of the road, horrifying these two individuals and greatly upsetting me that a vehicle sold by Volvo would perform so poorly and create a significant hazard to driver and passengers of the vehicle (not to mention others on the roadway). Again, and clearly, there appears to be some sort of electrical malfunction. Clearly, what we first reported to Volvo on or about May 17, 2021 was an electrical problem that Volvo had an idea or knowledge (knew or should have known) that was or may be similar to the problem they had already issued a recall for on the XC 40 recharge.
