Sometimes my doors when I walk away and sometimes they do not. I don't understand what causes them not to lock.
It's great that we're finally seeing Ioniq 5 topics not focused on scarce availability or exhorbitant pricing. Have you seen the Ioniq 5 Digital Owners Manual? I wasn't pleased when I tried to search for "lock" or when I searched for "door" because only the charging door comes up. I prefer searchable PDF owners manuals to interactive ones, but this one is pretty slick for second-best.
Here's another link to a protected PDF (I can't download the PDF file) Ioniq 5 Owner's Manual, but I couldn't find anything about walk-away door-locking, just automatic unlocking.
I've got the PDF downloaded but it's too big to upload. I opened it with Preview (MacBook) and printed it as a PDF and the size was reduced quite a bit but still 56.1MB is too big. ♂️ Page 228 speaks to auto locking while in the vehicle (removed from park or over 9mph/15kmh) but that's it when searching for "auto."
I notice automatic locking only after it has automatically UNlocked (walking past the car), and I then walk away (without having ever opened a door). This just happened this morning on my way past the I5 to get to my other car. John
So the no open re-lock many manufactures have been doing for years and Hyundai does as well. You could ask (chat) Peter, a content specialist in Canada, on his next or last (today) IONIQ 5 live stream your question in brief form. Peter can tell you if Hyundai ever has and possible try an IONIQ 5 out to see if it does. I honestly don't recall in any of his videos any Hyundai or KIA he is reviewing ever re-lock.
I believe that John is correct, it only locks when you walk up to the drivers door and it unlocks, then walk away without ever getting in. I was at a do it yourself car wash the other day and as I worked my way around the car it kept unlocking and re-locking! I finally put the key on a shelf to keep it from doing it.
As stated above, the Ioniq 5 automatically unlocks the doors when you walk by. If you walk away without opening a door, it will relock itself. If you don't want it to do this while you're washing your car (for example), just open then close a door manually. This will stop the auto unlocking until you manually lock the car (via the fob, door handle, or bluelink).
