I have a CX5 2013 Diesel that has done 130000 kms with the exact same symptoms as the you tube video. I've had a number of mechanics confirm that its either a head gasket or crack in the head and the only option available is to replace it with a 2nd engine costing $9000 as the cost of a replacement head and fitting would cost even more.
I am not the original owner and although most of the services have been carried out by mazda I have done the last 2 myself so this probably wont help my case if I contact mazda but I wonder if there is a way of finding out if my engine is one of the batch that arewere effected by that defective head gasket issue?
If it is I would definitely be contacting them and worth the wait for them to diagnose and repair at no cost.
I've also read that there is a legal obligation for them to fix these types of issues even out of warranty due to a clause stating that the vehicle is 'not fit for purpose'.
Any help on this would be really appreciated.
Cheers.
Hi DJ,
fyi!
From 2017,mazda Taiwan has stopped selling CX-5 or Mazda6 model equiped with 2.2D Diesel engine due to there were hundreds of cases reported on Mazda CX-5/Mazda6 2.2D
having head gasket blown issue,the obvious symptom is overflowing/boilng coolant from sub-tank caused by overheating of the engine.
According to the RIDICULOUS announcement of Taiwan's Mazda(
https://www.mazda.com.tw/news/offers/20180906/), the Skyactiv-D 2.2-liter diesel engine model is easy to increase the combustion pressure and temperature inside the engine if it is driven at a high level on a 5% steep slope. The investigation found that if this driving mode is continued,
high-pressure combustion gas will enter the engine coolant line through the cylinder gasket, which may cause the coolant to overflow from the sub-tank cover.
To prevent this from happening, Mazda Taiwan is currently preparing to change the engine's internal combustion pressure and temperature without excessively increasing through the engine control program.
It seems that Mazda is trying to fix this HW design issue through changing the SW(uhm).
however Mazda cannot commit 100% to fix it.
further more, based on our statistical data, one-third of the CX-5/Mazda6 2.2D users could encounter this issue ,especially, when the milage is >100000 km
Currently in TW, regardless of whether the vehicle is still in the warranty or not, mazda would replace a new engine for free, a new engine with the same design flaw, that's why we have someone here driving his Mazda6 2.2d with it's fourth engine.
