Stay away from Diesel Skyactive engines - They crack!
Added: 7th of January 2019
From personal experience point of view I would stay away from any Skyactive engine in the Mazda CX-5, Mazda 6 or Mazda 3. My engine block cracked after only 72,000km’s! with No overheating alarm. Note the Mazda doesn’t have a gauge but just a warning light that’s goes through a sequence of flashes if there is a problem but by the time that happens you’re already too late. The cost of repair was over 6,500EUR and not long out of warrantee I reached out to Mazda Ireland and Mazda UK and they refused to engage in any helpful discussions as to what could have been the root cause or any compensation. I’ve since learnt from getting the engine fixed it’s a common problem with the Skyactive engine that Mazda is just ignoring. I’ll be going for a car maker with longer warrantee next time. i.e. Not Mazda
