Complaint Summary
POWER TRAIN
Owner Narrative
On 8/20/2025, my 2018 Volvo XC90 T8 suffered catastrophic failure of the Electric Rear Axle Drive (ERAD). The vehicle suddenly developed a loud whining noise from the rear and became undriveable. This ERAD had previously been replaced under warranty at Boston Volvo Cars. On 10/28/2025, Queens Volvo inspected the vehicle and confirmed the failure was caused by improper prior service. Their technician documented that the ERAD housing was likely not properly torqued, which led to transmission fluid leaking over time, sludge buildup, and internal damage to gears and motor. The failure was sudden, confirmed by an authorized Volvo dealer, and the ERAD is no longer serviceable. This created a safety risk by causing immediate loss of propulsion and stability. If it had occurred at highway speeds, the risk of crash would have been significant. The failed component remains available for inspection.
