Ha ha, OK OK consumer report you got me.... Again nothing is always reported, and I concede this is a minor issue compared to main drive battery capacity degradation and 12v lead acid battery draining sporadically. My 2015 was within the free 3G upgrade so I can't complain about that. I had it upgraded but they tried to charge me. I had to educate them.
Yes the body is pretty solid and there are no rattles or things coming loose....
However these handle covers do break loose... it is NOT uncommon.
So there I win! It happens and there are a few threads on it. Also I called Nissan. See my "However to Nissan's credit" comment below. They know it is an issue and replace them under warranty all the time. Bottom line a 2015 Leaf SV should not shed it's door handle; it is annoying as hell, because you deal with it every-time you get in.
With that said a cheap DIY fix is easy with glue. If you want to avoid breaking handle outer shell loose, curl your fingers to the back of handle to pull, don't pull on chrome (plastic) cover.
However to Nissan's credit.... and much gratitude from me, Nissan offered to fix my 2015 (just) out of warranty. THANKS NISSAN... I have to pay for repair, and they will reimburse me. Part cost was $71 and Labor $93, total $164 with tax. Dealer cut me a small discount on part & labor. I'll send Nissan the bill, and they'll reimburse me. (This is the kind of thing that builds good will and loyalty. This is my first Nissan and happy with it. My previous brands Chevy, Mazda, Subaru, Acura/Honda, VW.)
FYI : If you want to DIY replace handle (verses a glue or tape fix) you DO have to take interior panel off to get at handle. There is a youtube video. It seems straight forward, less than 30 minute job. So you can fix it for $71 if you install it. Also the LHS and RHS handles are identical, same part number, but it says RHS....
