I am facing this issue since last 6 months, and I have shown this to my local mechanic as well as to Subaru dealer and no one find the issues or problem with it.
After every cold morning when I want to unlock my Subaru car I can only unlock driver side and all 3 passenger side doors remains lock. The only option is to unlock from inside manually.
This issue only happens in early morning when weather is cold but after that during day i can unlock all 4 doors without any issue I believe whether weather is warm.
I would like to mentioned that I got my battery replaced in Dec last year as I was told by dealer that battery is 35% efficient and that may be causing not to open up, but this has not been solved.
Hence putting this request on forum and hope some one had this issue earlier and got it resolved.
I am based in NSW Bankstown area .
