Automatic Emergency Braking problems of the 2018 Subaru Forester

Starting up the car in the morning after a long day stuck in traffic (over 100 degree f weather), moved about 5 feet then the eyesight system stopped working, rear braking stopped, and power steering gave out - the car started and the engine ran normally. The car was abandoned as unsafe until diagnostics could be performed and a different car was used to get around . That evening the car started up fine, also the next morning to reproduce conditions. Tested the battery, which showed "good" (93% charge/40%healthy). I suspect that, in the morning the a/c, headlights, radio, backup lights, etc. . . Put a large draw on the electrical system resulting in a system wide shutdown of adaptive features - however loss of power steering is insane and can easily result in death if it happens while driving especially while making a turn if the driver is not prepared/strong enough to force it. The linking of non-critical system to help the driver to an essential system is just asking for trouble.

Component: eyesight camera motherboard failure due to cold weather (code b28b3). Possibly an improper conformal coating that is susceptible to cracking or building moisture which then freezes and cracks components of the camera system. Safety concern: it appears this is common in Subaru eyesight systems for all models years 2017-2019. A local mechanic shop (fairbanks, ak) has seen these systems fail repeatedly in our winter climate. I find this concerning that the system that has the ability to control steering and breaking is susceptible to what we consider normal winter climates. Subaru has been vague on the cause of this issue. Reproduced: yes, this is known and not uncommon per the Subaru dealer service center and an independent local shop. Inspected: yes the vehicle has been inspected by kendall Subaru of fairbanks ak. Warning lights: no warning before failure. Currently the display shows "eyesight" in bold indicating the eyesight system is non functional.

After ice storm and after car was cleaned of any ice, the emergency braking appeared to be confused by the ice on the road. I decided to not go forward once I was on the street as it seemed to slick and tried to back up to my house to get into my driveway which is on a slope. In reverse, the brakes kept slamming on after a foot or two and I would lose momentum and slide forward. I ended up having to drive forward around the block forward to get back to my house. The eyesight system seems to get confused very easily when there are icy reflections or snow on the road.
