Warning problems of the 2017 Subaru Forester

Two incidents happened first battery died, we replaced the battery. Then battery died again, we replaced the alternator on June 5, 2025. Then on Saturday September 13, 2025; all system lights came on at once on the dashboard then the battery died again. Car locks up and is stalled out. Cannot restart car, has to be towed. We replaced the battery cable and cleaned the terminals. Three months later, December 1, 2025; the battery light came on then all system lights came on at once, the battery died again. This happened on interstate 95, it could easily have caused a crash. Car locks up again and is stalled out again. Cannot restart car again, has to be towed again. Something in the electrical is causing this, we do not know what.

My 2017 Subaru Forester touring (VIN: [xxx] , 118,200 mi) has a recurring eyesight failure where the system becomes disabled and will not complete camera registration or calibration. Subaru of sterling (va) diagnosed active code b28a0 “vehicle model judgment” and noted that the eyesight stereo camera would not accept vehicle model registration. The technician documented: “error for camera adjustment incomplete. When attempting to relearn ui for eyesight camera, system is not taking vehicle registration; suggests camera replacement and perform recalibration. ” this occurred after a confirmed dcm/starlink parasitic draw had caused repeated low?voltage conditions until the dealer reset the dcm to factory mode (per the “no further draw present at this time”), suggesting eyesight registration may have failed due to prior voltage instability rather than true hardware failure. Subaru's service flow for b28a0 indicates this code can occur when the model write/registration is incomplete, interrupted, or mismatched—not necessarily when a camera has failed. Subaru lists causes such can communication issues, incorrect model registration, incomplete write due to ignition timing, or power/fuse issues during aiming (eyesight diagnostic manuals). I am reporting this to NHTSA because eyesight is a safety-critical system that governs adaptive cruise, lane keep assist, and pre-collision braking. My dealer is recommending camera replacement without documenting that Subaru’s required pre?replacement steps (model registration inspection, can/lan re-scan, voltage and fuse verification, genuine-part verification, etc. ) have been completed. I request odi review because eyesight should not fail to register unless hardware is defective or a procedural/voltage issue exists. I want this documented in case this represents a broader pattern of eyesight registration/calibration failures on Forester models using the same stereo camera platform.
