Turbo, oil pump, oil dilation, timing chain, injectors, DPF, electrics, the list goes on. And on. And on.

Avoid diesel Mazda 6's like the plague if you value your sanity. I have had this car a few years and it is time for it to go, many amounts of money later, things still are not right with it!

Simply not worth it, I bought a looked after low mileage example, thinking I would fix a few things and it would be fine, but no - it was one thing after another.

Used dealer I bought the car from would not help as it was out of warranty when things started to go south. Main Mazda dealer didn't want to know either and I struggled to find any other independent garages or mechanics willing to work on this car. The engines still smokes and stinks of oil after all the work I have done! It does not compare to my old 2006 VW Passat which saw 200,000 miles before any major issues. Well this 2013 (first of the new shape) Mazda 6 only has about 90,000 miles on it now and it feels worthless.

Speaking of which, I have tried to sell it very cheap for spares and repairs and still no one wants it; all I have had is enquirers asking if I will break it up and sell it part by part. Someone really wants its nice alloy wheels! Speaking of which, that is the only good thing about this car - for a Japanese family car, it is very nice looking inside and out.

Performance and economy were actually good as well (when it was running right initially) and I enjoyed driving it. Shame really, could have been a nice car, so if you really want a Mazda 6 of this generation and are taken with its looks as I was, get a petrol one. Avoid the diesels. Avoid AVOID!

Other than the wear and tear expected of age and miles, basically nothing serious.

ABS sensor.

The climate control is a little hesitant to work.

Tiny rust patch on rear wheel arch; I am going to repair it before it gets worse.

General Comments:

"New" model for 2013 Mazda 6 is a very stylish and comfortable car. Mine is bright red.

I went for the 2.0 petrol engine which I was a little unsure of at first as most are diesel. But I am glad I did go for this - it is very smooth and refined and still manages around 40 mpg or more pretty easily. Good power also.

Very nice to be in, dark grey/black cloth interior has sporty seats and a comfortable position. Controls are nicely laid out, long motorway journeys are a pleasure. The SE-L model has plenty of equipment and nice alloy wheels.

Handles very well, gear-change is slick, interior is spacious.

Getting on a bit in age and miles, but still feels solid and modern, hope to keep it a long time. As with any car it should last if looked after.
