NHTSA Complaint #11708737 — 2015 VOLVO XC60

Component/System that failed: The engine (T5 Drive-E) experienced sudden loss of propulsion and entered reduced engine performance mode. The vehicle is currently available for inspection and was towed to an authorized Volvo dealer following the incident. How safety was put at risk: On July 3, 2025, while driving approximately 75 mph on a crowded interstate highway in rural Ohio with cruise control engaged, the vehicle suddenly and without warning lost propulsion. Traffic included semi-trucks and other vehicles, with limited shoulder availability. The sudden loss of acceleration at highway speed created an immediate risk of rear-end collision and left the vehicle unsafe to operate. Confirmation or reproduction: Prior to the failure, in July 2024 at approximately 92,000 miles, I reported abnormal oil consumption to an authorized Volvo dealer and raised a known Volvo service advisory related to oil consumption in the T5 Drive-E engine. The dealer acknowledged the advisory but refused testing, stating the vehicle did not meet Volvo’s internal threshold. After the failure, a service agent acknowledged that this issue is known to occur in this model at approximately this mileage. Inspections: The vehicle was serviced at an authorized Volvo dealer in Bethesda, Maryland just days prior to the incident. Following the failure, the vehicle was towed to an authorized Volvo dealer in Columbus, Ohio. Volvo Cars USA has not repaired the vehicle and denied a goodwill request. Warnings or symptoms prior to failure: There were no warning lamps or messages prior to the loss of propulsion. The engine warning light and a “Reduced Engine Performance” message appeared only after power was lost.
