Complaint Summary
POWER TRAIN
Owner Narrative
My 2020 Subaru Ascent experienced a sudden failure of critical safety systems due to CVT fluid leaking through the transmission pressure switch into multiple electrical components. This fluid leak damaged several wire harnesses and the Engine Control Module (ECM). The check engine light came on and all Eyesight safety features disabled. Subaru has confirmed this will cost over $9,400 to repair. This issue appears to be related to known Subaru Technical Service Bulletins, including TSB 16-103-16R and TSB 02-170-17R, and matches the description in NHTSA Campaign WUV-07. Subaru of America has refused to fully cover the repair, even though my car is well maintained, has only 54,000 miles, and is just 4 months outside the powertrain warranty. This is not normal wearâitâs a serious defect that causes electronic failure and disables safety systems while driving.
