Other Fuel System Related Problems of the 2020 Volvo XC60

Other Fuel System problem

On July 28, 2026, while driving my 2020 Volvo Xc60 t8 polestar engineered, the vehicle repeatedly displayed “hybrid system failure – service required,” together with the check-engine light and hybrid/battery warning indicators. The warning repeatedly reappeared while the vehicle was being driven. I brought the vehicle to an authorized Volvo dealer, north point Volvo, on July 30, 2026. The dealer diagnosed a fault in high-voltage battery cell module “b” and documented that the module requires replacement. Repair order #522934 states that the replacement parts are on order with “no estimated time of arrival. ” the dealer advised me that the vehicle was mechanically safe to drive as long as I did not charge it. Because the hybrid-system failure warning repeatedly appeared while driving and the diagnosed fault involves the high-voltage traction battery, I did not consider continued operation appropriate. The vehicle remains unrepaired at the Volvo dealer. I am reporting this because the failure involves the high-voltage propulsion battery and occurred while driving. I am not aware of any crash, fire, injury, or loss of propulsion associated with my incident.
