2021 Volvo XC90 Electrical system Problems

“*with the bowers & wilkins sound system* twice within 1400 miles, there was a loud pop sound from the speakers followed by no sound from any portion of the vehicle. The pop sounded like a window or the sunroof shattered. All sound was lost: sensus feedback, turn signals, parking sensors, phone, etc. The only thing that worked was the bass. After the car was parked and off, and re-started, everything worked as normal. Oddly, there was the feeling of static electricity just prior to each pop. These pops were caught on dash cam for proof. There was static heard in the dash cam video too. …”

“The check engine light on our Volvo XC90 Plug-in Hybrid came on stating Hybrid System Failure Service Required . The vehicle would no longer accept a charge. A service appointment was made and the technician found that there was a fault with cell module A. A case was started but we were told the part was on backorder.”

“My 2021 Volvo XC90 Recharge has experienced multiple hybrid system failures under Volvo's factory 8-year/100,000-mile hybrid warranty, with fewer than 45,000 miles on the odometer.

Critically, my vehicle has suffered two actual battery module failures, not preemptive recall replacements. …”

“The infotainment system has locked up and has shut completely off while driving. When it shuts down (screen goes black) or glitches, the car actually loses power. Luckily it powered right back on but it was scary and could happen again and be much worse. The screen/ infotainment system has had this issue for awhile. We’ve even told Volvo of Tulsa about it when it was in for service but they said they couldn’t do anything about it because they couldn’t reproduce the issue. We have also had the brakes and rotors replaced twice at the dealership because they seem to be lemons or faulty. …”

“The contact owns a 2021 Volvo XC90. The contact stated that while driving at various speeds and depressing the accelerator or the brake pedal, the vehicle hesitated with the check engine warning light illuminated. The dealer was contacted. The vehicle was taken to the dealer to be diagnosed, and it was determined that the electric rear axle drive system had failed and needed to be replaced. The contact stated that the failure occurred each time the vehicle was driven. …”
