You ask, we deliver. You've been asking (well, sending abusive emails) why have we stopped shining a light on the carmakers ripping off wood ducks.

But then like a bolt of lightning from the sky came reader Gordon from Queensland who, wait for it, has a problem with his 2019 Mazda CX-5 Diesel. Be still my beating heart.

As the 15 regular readers and one friend know, from September 2017 I have been warning the buying public not to drive or buy a Mazda CX-5 because of both safety (ie: you and your family could die) and cost issues.

Now before you send me more emails about the great experience you have had with your CX-5 let me just point out I currently race (unsuccessfully) a Mazda, have owned a Mazda BT50 which I loved and some of my best friends are Mazda owners. But the CX-5 has a drive shaft disengagement problems and oil accumulating in the sump issues.

Now Mazda first deal with any problems by telling their dealers to say: "We've never seen these problems before." Then, if you persist, the dealer will say: "Mazda are providing engine replacements outside warranty where there are problems like yours."

Then if you say that's not a solution, like reader Gordon did, the dealer will tell you: "Ring Mazda customer service." You will ring them and be told after two weeks that "the engine was running to specifications and your request for refund or replacement is denied."

Gordon takes up the story from here. "I then wrote to ACCC, who advised me that they only dealt with 'broad national issues', another way of saying that they have not bothered to read my complaint, which made clear that Mazda have been selling defective diesel engines since 2012 and fix them, as required by Australian consumer law, only when they have no other alternatives."

I have read many writers' views: that ACCC are "time-wasting navel-gazers", "lazy incompetents" and "have trouble aligning the buttons on their cardigans."

If then you contact a motoring writer for help the journalist will contact Mazda PR operative Sonia Singh who will say: "Mazda does not comment publicly on matters relating to its customers."

Over the past few years I have tried really hard to do something about this. Dealers tell me they are embarrassed by what head office tells them to do and service staff will often apologise to owners for Mazda's appalling behaviour.
