Most Recent Complaints

#11714272 | SEAT BELTS | | N/A miles
2021 Subaru Ascent (VIN#***). Water found dripping down both second row seatbelts on multiple occasions during or following heavy rain, accumulated into mold growth on the carpet in front of second row seats to the front of the 3rd row seats (cargo area dry, front footwells dry). Authorized Subaru dealer technician report (dated 10/29/25 and 12/3/25 copy pasted into email) explicitly documents 'condensation build up on the interior of roof (seat belt area)' due to unlocated water intrusion. The dealer attributes this to 'leaf debris' in the front cowl area and rear hatch hinge despite the leak occurring at the rear C-pillar (and notably cargo area and front footwells showed no moisture making this physically impossible). Despite confirmed moisture exposure to critical passive restraint systems, the dealer relays that the manufacturer has issued a verbal-only warranty denial (stating no addl records exist aside from the initial technician report) and suggest the only repair be carpet replacement, with refusal of confirmation of the source of the leak and no proposal of replacing the 2nd-row seatbelt retractors nor provide a written safety guarantee. The vehicle is covered by an active 8yr/120,000-mile Subaru Gold Plus Added Security Plan (Agreement #*******, started on 8/2/21), yet the manufacturer is refusing to honor the contract for the defect or the resulting biohazard ('mold spouts' documented by their technicians on carpeting and into the foam). This unaddressed moisture creates an unreasonable risk of internal corrosion and failure of the seatbelt G-sensor/locking mechanisms on both sides. Also as an immunocompromised owner (due to medication for multiple sclerosis to such an extent that requires monthly IVIG infusions), the documented mold is a significant health hazard. Vehicle has only 15,166 miles. Correspondence with dealer and SoA as well as agreement# are available on request. Date of incident was when taken to dealership (events in summer/fall 2025)

#11712180 | ELECTRICAL SYSTEM | | N/A miles Fire
While driving my Subaru Ascent, a check engine warning light appeared on the dashboard. Shortly afterward, I noticed smoke coming from the engine compartment. I immediately pulled over and turned the vehicle off. Within moments, flames began coming from under the hood. The fire spread rapidly, and within 5-10 minutes the entire vehicle was fully engulfed in flames. The fire originated from the engine compartment. The vehicle was a total loss. Subaru of America was notified on 12/23/2025, but no follow-up or update on investigation has been responded. The vehicle was always serviced with Subaru. This sudden, traumatizing and catastrophic failure with no prior warning.
