2020 Volvo XC60 problems

“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.”

“Vehicle with 34,000 miles has started to have surging of rotors when applying brakes at 33,000. Vehicle has had brake disc kit replaced due to warping at 13,058 miles. Vehicle had brake disc kits and front and rear brake rotors replaced due to high spots for pad engagement at 22,996 miles. The vehicle has a continuous problem with brake/rotor system!”

“Good Morning: I've attached a letter that I've written to Volvo USA regarding their security lug bolts on the wheels of their vehicles and the adapter that they provide to remove this. I found out after incurring a flat tire that these adapters are often non-functional and that the dealer is well aware of this. I think this is an issue that Volvo should address for all current and past owners. Also, during this incident I experienced what I think is a flaw in their tire pressure monitoring system - it illuminated a yellow caution which, I've seen happen when one tire was not at the same pressure as the others. In this instance the tire was flat. Shouldn't that warrant a different indication? Thank you for your attention to this.”

“Severe oil leak coming from the engine. I had it in the Volvo Dealership, they claimed it was due to a loose oil filter. When I drove the vehicle home and parked in my driveway, It started to stain the driveway with a fresh oil leak.”

“The seal on my 2020 Volvo XC60 moonroof allowed water to leak under the floorboards. My car is only 6 years old. We had a lot of rain over a short period and I noticed the sound of water sloshing around under the floor. Nothing was wet inside the car. My Check Engine light came on as well. I took it to the Volvo service dept. They are now saying wires are corroded and that it will cost me over $11,000 to fix this problem. Again - my car is only 6 years old, and less than 70K miles. With my previous Volvo, that I had for 18 years, I never had this problem.”
