Complaint Summary
FUEL/PROPULSION SYSTEM
Owner Narrative
On September 30, 2025, a 2016 Volvo XC90 T6 experienced sudden engine failure while driving westbound on I-75 (Alligator Alley) at highway speed. The vehicle abruptly went into reduced power mode (âturtle modeâ) without warning. This forced the driver to stop on the roadside, creating a serious safety hazard in fast-moving traffic. Component/system that failed: Engine / Power Train. An independent repair facility performed diagnostics on October 6, 2025, including a compression test. Results confirmed that one cylinder had lost compression due to a failed cylinder head. The mechanic attributed this to excessive oil consumption from defective piston rings, a condition documented in Volvo technical bulletins. Inspection: The vehicle was inspected by an independent service center. Photos and test results are available for inspection upon request. The manufacturer was contacted and denied assistance, citing mileage, despite known oil consumption defects in this engine family. Safety risk: The sudden loss of power at highway speed put the driver and other motorists at risk of collision. With no advance warning, the driver was left stranded on a dangerous stretch of interstate. Reproduction: The failure has been confirmed through diagnostic testing and inspection by the independent service center. Manufacturer/police/insurance inspection: The manufacturer has been notified, but no inspection by Volvo has occurred to date. No police or insurance inspection was performed. Warning messages or lamps: Prior to the breakdown, no warning lamps or messages indicated impending failure. The first and only symptom was the sudden loss of power on the highway. Incident cause assessment: Based on mechanicâs findings, the underlying cause is piston ring/oil consumption defect leading to cylinder head failure. This defect is widely reported in Volvo vehicles with this engine and represents a safety-related condition.
