2023 Volvo XC40 B4Recalls, problems, MPG & safety

“Liquid intrusion in the center console from a routine cup holder spill penetrated unshielded wiring harnesses. This caused progressive electrical failures, including loss of engine power and power steering, failure of the SRS passenger airbag occupant sensor, 12V battery drain, and uncommanded movement of the power driver's seat while driving—which surged forward and pinned the driver against the steering wheel. Dealer repairs are approximately $5,000 to date with active hazards remaining”

“The vehicle intermittently loses all audio output, including music/media, turn-signal sounds, lane-change/blind-spot warning tones, parking/reverse proximity sensor alerts, and other vehicle chimes. I have experienced this problem for more than one year, and it has become significantly more frequent/severe following the latest software update. When the failure occurs, visual displays and cameras may continue to function, but the associated audible safety warnings are completely absent. This creates a safety concern because the driver may not realize that important warning tones are unavailable, including while changing lanes or maneuvering near other vehicles or objects. The issue can temporarily be corrected by rebooting/resetting the vehicle's infotainment/head-unit system, but the problem returns. We have had to perform this reset at least 10 times in the past several months. The problem appears to involve the vehicle's electrical/infotainment audio system and affects multiple safety-related audible warning systems. The issue existed prior to the most recent software update but has worsened since the update. The vehicle is available for inspection if requested.”

“On August 25, 2026, with my family in the car, my 2023 Volvo XC40 Recharge issued a collision-avoidance warning when there was nothing in front of us. No crash, injuries, or damage resulted. I reported the event in writing to the selling dealer, Volvo Cars Danvers, on September 15, 2026. This was not an isolated event. On September 4, 2026, the system activated again while the car was sitting still in traffic, stopped a safe distance behind the cars ahead; that event was reported separately. Despite repeated written requests beginning in early October 2026 for the manufacturer's event reports for these events, the dealer has produced no report or account for either event. I am concerned that a driver-assistance system that warns without cause could cause a sudden, unexpected vehicle response in traffic.”
