2013 JX35 loses power, won't start - scanner codes

My 2013 JX35 was running well then started losing power while driving (AC stopped, "IBA Off" light flashed on dash). We pulled over and couldn't get it restarted so we installed a new battery and drove home without any issues on the new battery.

A few days later we drove about 30 kms on the new battery then it lost power again and broke down on the side of the highway again. We had it towed to the mechanic who said it had fired up without any issue, said the battery and alternator were fine. He scanned and thought it was a crank shaft sensor and replaced it (one of four).

We brought it back home (drove fine) and now it doesn't want to start. We ran a scanner and got the attached codes.

At this time when I try to start I get "BSW Malfunction see owners manual" as well as the following lights: battery, check engine, PS, IBA Off, brake warning light (exclamation mark) and master warning light ( ⚠) - see attached photo.

Anyone have any experience with anything like this? Any ideas?? Thank you so much!
