NHTSA Complaint #11701998 — 2021 VOLVO S60

2021 Volvo S60 T8 AWD, VIN [XXX] , ~71k miles Component: SUNROOF / DRAINAGE SYSTEM / ELECTRICAL SYSTEM Summary: Water entered the passenger compartment through clogged sunroof drain hoses and accumulated under the front passenger seat, causing catastrophic failure of wide angle module (WAM) and related electronic components (incl. front camera and wipers). Description: After moderate rain, a large amount of water was discovered under the front passenger seat. The vehicle began displaying multiple warning messages (camera faults, wiper faults). The authorized Volvo retailer diagnosed failure of the WAM and other modules due to water intrusion originating from the sunroof drainage system. This is a known, recurring defect acknowledged by Volvo in multiple Technical Service Bulletins: - TJ 31372-2 (Water leakage via sunroof drain hoses) - TJ 35382 (Updated drain hoses - new part number) - TJ 29322-3 (Water ingress passenger footwell / CEM area) The original drain hoses are too narrow and prone to clogging, causing water to overflow into the passenger compartment instead of exiting the vehicle. This creates a serious safety risk: - Potential failure of SRS airbag system - Loss of electronic stability control and ABS - Loss of 360 camera and blind-spot monitoring - Risk of electrical fire or short-circuit - Failure of wipers (mine stopped working when I was driving under the rain) Repair estimate: $17,825 Repair is going to be delayed over 2 months awaiting parts from Sweden. Vehicle was properly maintained; 70,000-mile service performed at authorized Volvo retailer on 9/24/25 - no drainage issues were noted or addresses at that time. This identical failure has been reported by hundreds of owners of 2019-2024 SPA-platform Volvos (S60, V60, XC60, XC90) on NHTSA complaints, Volvo forums, and in ongoing litigation. Despite multiple TSBs and redesigned parts, Volvo has not issued a recall or notified owners of the need for preventive maintenance.
