I own a 2021 Volvo XC40 Recharge (pure electric). At 49,030 miles, while slowly driving in a parking lot, the vehicle suddenly began shuddering and jerking as if driving over rumble strips. A warning message appeared stating “Propulsion System Failure” and indicated the vehicle would reduce speed. The vehicle lost propulsion and came to a stop. After stopping, the vehicle would not re-enter Drive or Reverse and could not be driven. It was stuck in position in the parking lot but not in a parking space. The instrument cluster and infotainment systems still powered on, but the vehicle repeatedly displayed messages such as “Vehicle system check. Wait” and would not enter a ready-to-drive state. The vehicle had to be towed to the dealership with a dolly. It took 4 hours to move it because the first tow truck could not safely move it with the wheels stuck in place. This failure occurred without prior mechanical warning or other preceding symptoms. Dealer diagnosis identified an internal failure of the front axle inverter high-voltage assembly (IHFA). Service records document a 400A fuse failure, welded battery disconnect unit (BDU) contactor relays (R1 and R2), and overheating/damage to high-voltage battery disconnect components. Repair required replacement of the IHFA, BDU contactors, and high-voltage fuse. The dealership stated this was not a normal wear-and-tear issue. I have since found reports from other Volvo Recharge owners describing similar propulsion failures involving inverter and high-voltage battery disconnect components. My safety concern is the sudden loss of propulsion while the vehicle was in motion, with no warning and complete vehicle immobilization. Had this occurred at highway speed or in traffic, it could have created a serious collision hazard. The dealership service person agreed that my only chance to get the vehicle to a safe location was to coast. After that, it'd be stuck. I was unaware of this, which is itself an issue of concern.

I was sitting in the car with my daughter with the car in park, but the engine was on. Suddenly the engine started revving, and I thought her foot hit the peddle but it wasn't the case, and she had to turn the car off. I then got into the driver's seat and started the car again, and it did the same thing. I turned the car off and had to Uber home.

The contact owns a 2021 Volvo XC40. The contact stated that while driving approximately 30 MPH, the vehicle unintendedly decelerated. The contact was able to pull into a nearby parking lot where the vehicle stalled. The vehicle was towed to the dealer, who diagnosed the cause of the failure and repaired the vehicle. The contact believed that the battery and drive train were repaired. Approximately 2 to 3 years later, while driving approximately 20 MPH, the vehicle started shaking, lost motive power, and stalled. Law Enforcement arrived on the scene, and while assisting with moving the vehicle from the middle of the road became aware that coolant was leaking underneath the vehicle. The vehicle was towed to the dealer, who diagnosed the vehicle with coolant intrusion into the engine. The contact was informed that the inverter drive system and wiring harness had caused a catastrophic drive failure. The vehicle was not repaired. The manufacturer was made aware of the failure, and a case was opened. The failure mileage was approximately 10,000.

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.

Ever since I bought the vehicle new in 2021 I have had perpetual problems with the software and technology. The cruise control system has gone out completely, all electrical fails in the vehicle, apple car play regularly goes out. What is even more of a safety concern is multiple times my car has been automatically braking and suddenly accelerates nearly causing me to rear end the vehicle in front of me. Several times I have been traveling down the road straight ahead with the cruise control system enabled and the vehicle will suddenly automatically turn sharply throwing me towards oncoming traffic or towards the side of the road. Fortunately I have been able to prevent an accident every time because of quick action but this is deeply concerning and an extreme safety concern for me and others on the road.

Back up camera consistently does not turn off. Audio system, including turning signals and reverse alert do not activate. This continues to be a safety risk despite numerous software updates that have allegedly fixed the issues.

The supposed software fix for the rearview camera not being available did not solve the problem. I’m still getting “Camera is temporarily unavailable.” When shifting into reverse. Vehicle was updated to software version 3.7 and this issue persists.
