Well, I guess everyone's mileage varies but the RX1 and RXRII that I owned never had an issue in the many years that I shot them. If anything was an issue it was probably the clumsy eyepiece for the RX1RII that I eventually lost and had to replace.
I drive a Range Rover too and I've grown weary of people telling me how unreliable my vehicle is even though after having owned several I've never suffered the problems that others seem to suffer. My point being that ALL systems and things have issues and you're either lucky or not, or perhaps your use of the product is different such that you don't run into these issues.
I know how that goes, because I've never had anywhere near the number of the issues with my Audis over the years that others apparently have had with theirs. My Cayman, on the other hand, went through a bad case of the 100,000 mile blues, first blowing up the clutch and after I fixed that, comprehensively destroying its engine a few thousand miles later. Now the headliner has failed, drooping from the roof onto my head and covering my eyes, and it won't pass emissions, either, because the fuel tank vapor recovery system has failed as well.
But whenever I drive it, all is forgiven and the same has been (mostly) true when it comes to taking photos with my RX1s, too!
And btw, I do understand the unreliable camera issues. My Leica M8/M9 & various lenses being out of calibration with each other was a total PIA until I stopped dealing with Leica and instead worked with a Leica repair specialist (DAG).
Fortunately, I do almost all of my maintenance and repairs myself, be it my cars, my cameras, my house or what have you. Right now, I'm wrestling with finding and fixing all the leaks in the 30-year old sprinkler system in my backyard ...
grrrr.
