There are 6 owner-reported fuel system complaints for the 2021 Volvo XC40in NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
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.
When attempting to park the vehicle, at low speed, the vehicle performed an unintended acceleration leading the vehicle to crash.
I was driving this car on Highway 99 on 7/11/2025. The dashboard flashed the message " Stop safely The vehicle will stop Propulsion system failure." I cut the lane and stopped my car on the Highway 99 shoulder. Just right, my car stopped on the Highway shoulder; it disabled itself and couldn't move at all. The gear shift can't shift to neutral (N). From the first message appearing on the dashboard to the car being disabled takes just a couple of seconds. When it happened, it was about 6:30 pm, rush hour. If I had not had a chance to drive the car immediately to the highway shoulder, the vehicle would have stopped in the lane, and I would have been crashed into by the cars behind me. This could lead to a catastrophic traffic accident. I want to mention that when the message appears on the dashboard, there is no sound alert. When people drive on the highway, their eyes are most likely focused on the road. Without a sound alert, people may not be aware of the message present. I contacted to the manufacturer on the 7/13, Sunday, they said they will open the case to investigation. As I report this incident, I have not heard from them yet. I uploaded the message photo that appears on the dashboard when the incident happened. Let me know if you need any information from me. Thank you!
In approximately May of 2023, my vehicle experienced "propulsion system failure" per a dash board light, and would not drive. I had it towed to Volvo and they told me that it was a known defect that required a software upgrade. They upgraded the software. In May of 2024, the car had a second propulsion system failure. The Volvo dealer found the error code and light on the dash, followed diagnostic procedures and saw that the software is up to date. They opened a case with Volvo and Volvo informed them that they are aware that propulsion system failures are occurring even with the updated software installed. They are planning an upgrade but have not yet completed it or made it available. Thus, Volvo knows that the propulsion system can fail, including when the car is in driving, and has not advised consumers or corrected the problem.
Very frequently (4-5 times a week) the charging cable will not release from the vehicle. Pushing release button resolves to flashing yellow, red, or green lights, but does not release. Sometimes will release from console, but not always. Locking and unlocking the vehicle, repeating all the above several times will eventually release the cable. This may be related to the erratic charging process where the car may or may not charge after being driven or left overnight. Dashboard may show initializing, or show that it is not charging when it is charging, or vice versa. Dealer stated could not duplicate, but software update would fix it. No code, no problem as they say in Sweden. Driving the 15 minutes home from the dealer resulted in the car failing to charge, and the cable refusing to release. This problem has been duplicated using a home Chargepoint charging system cable, and the supplied Volvo charging cable on two different 50amp outlets in the garage. The inability to remove the charging cable quickly in an emergency may lead to serious or even fatal consequences. A quick Google search shows that this is a known problem. There are other erratic system problems in the vehicle which by themselves may not be serious or fatal, but lead to increased driver distraction which could be serious or fatal.
Complete power failure of the vehicle. Inability to start or move the car. Car cannot be locked, wheels are locked, no power to the vehicle
