Hi, I'd quite like one of these but the following issues in HJ review really worrying. How widespread are these issues and how disasterous (costly) if they occur? ( I have googled electrical issues and not found much info...) Thanks!

18-6-2014: Stress cracks across the windscreens are becoming increasingly common because the edges of the glass are exposed at the screen pillars where they are vulnerable to stone chips. These then turn into cracks right across the screen, same as on a Mazda 5.

3-9-2014: June 2014 Mazda CX-5 plagued with persistent electrical gremlins that the dealer has been unable to rectify.
