2021 Volvo XC40 Problems: 7 Known Issues

On the 2021-2025 Volvo XC40, the XC40 Recharge (fully electric) has widespread reports of 12V auxiliary battery drain, resulting in a completely dead vehicle that cannot be unlocked, started, or charged. The 12V battery powers the vehicle's computers, door locks, and charging system initialization. The drain is caused by multiple control modules failing to enter sleep mode properly, continuously drawing power from the 12V battery. Cold weather exacerbates the drain. Volvo has released multiple OTA software updates to address module sleep behavior, but the issue persists for many owners, especially if the vehicle sits unused for more than 3-5 days.

On the 2021-2022 Volvo XC40 Recharge BEV twin motor (78 kWh pack), in the XC40 Recharge BEV the Battery Energy Control Module (BECM) supervises the traction pack contactors. A microprocessor fault causes the BECM to reset while driving; on reset it opens the high-voltage contactors as a fail-safe, instantly disconnecting the traction battery from the drive units. The result is an abrupt, total loss of propulsion at speed with no warning — the car coasts, power steering and brake assist remain but regen and drive are gone. This is distinct from the well-known 12V accessory-battery no-start: here the 12V system is fine and the vehicle is already moving. NHTSA campaign 21V109000 covers 2021-2022 XC40 Recharge.

On the 2019-2024 Volvo XC40, the Sensus infotainment system in the XC40 is prone to screen freezes, random reboots, and unresponsive touch inputs. The vertical 9-inch touchscreen can go black for 30-60 seconds before restarting, temporarily disabling climate controls, navigation, and backup camera. The issue is linked to software memory leaks and insufficient RAM allocation. Volvo has released multiple over-the-air (OTA) software updates, but the fundamental hardware limitation persists. The 2024+ models with Google Built-In (Android Automotive OS) have different but still present software stability issues.

On the 2021-2025 Volvo XC40, a long-running software defect in the XC40's camera/display chain leaves the center screen blank, frozen on the previous view, or showing only guidelines when reverse is selected. This is a FMVSS 111 non-compliance, not a cosmetic glitch, and it is separate from general infotainment reboots — the rest of the system can be working normally while the reverse image never appears. Volvo issued recall 25V282000 covering 2021-2025 XC40 and related models, then superseded it with 25V908000 after the first remedy proved insufficient, which is why some owners saw the fault return after being told it was fixed.

On the 2019-2025 Volvo XC40, the wiring harness that passes through the tailgate hinge breaks from repeated flexing, causing the rear camera, wiper, defogger, or power tailgate to stop working. This is a common Volvo platform issue across multiple models.

On the 2021 Volvo XC40, the front seat belt retractors have an automatic locking retractor (ALR) mode that is engaged by pulling the belt fully out — the mechanism parents rely on to cinch a forward-facing child seat or booster tightly to the seat. On affected XC40s the ALR releases back to emergency-locking mode prematurely, so the belt pays out again and the child restraint is left loose on its base. The seat feels tight at installation and works loose over subsequent drives, which makes the defect easy to miss. NHTSA campaign 21V682000.

On the 2019-2025 Volvo XC40, the fuel pump control module fails, causing the engine to stall, not start, or lose power while driving. Volvo issued a recall for some VINs. The module is located near the fuel tank and is susceptible to corrosion and vibration damage.
