2012 Mazda CX5 diesel engine head gasket
I have a 2012 Mazda CX-5 diesel engine with 148k in odo. My car was running fine untill i saw all the lights coming on dashboard and the car lost the power. I pulled over and towed it to my regular mechanic. He fixed it. And now the car is taking a lot of coolant. I had a engine recall. Took it for recall and told them the coolant is losing quickly and there is no any leak. They said they fixed the recall but didnt bother to check the coolant loss. Now i found out that its a head gasket blown. I talked to one of the mazda service near my home and they straight away denied to take my car in and told me to take it to where i had my recall done.
They also said that the car has a bad history in mazda service history.
Has anyone faced this problem of head gasket in diesel engines and i am worried if i have to get the engine replaced out of pocket, its going to be a big out of pocket.
Any suggestions please.

Unfortunately its a not too common problem with these engines.
Book it in with Mazda, inform them of the issue, inform them of your online research. If you get nowhere at the dealership, hit up Mazda Australia direct, and cry over the phone if necessary.
Depending on the service history, you many end up with a free engine.

Thanks. I own this car since 2017 and i have been servicing it with my own local mechanic (Ultratune) and one of the mazda repair from sydney told me that is a bad decision. Now i have not serviced the car in mazda since i owned, is there any possibility that i might get an engine replacement?
As per your understanding do you think the problem is a manufacturer’s defect?

Another 2012 CX-5 Diesel with the Dreaded Head Gasket issue
I've a 2012 CX-5 Diesel (NZ new) with approx 160,000km's. Had an issue in 2019 and the local Mazda dealer charged me approx $2k for the following (from their workshop report):
Anyway, given the history of this model and the obvious design fault leading to this problem, I'm taking civil action via the Disputes Tribunal. This is as much a matter of principle as anything else. I'd welcome any similar evidence/experiences from others on this thread to support my case. I also have an independent mechanic who has already replaced six engines on this model (Imports); so he's prepared to write a comprehensive report as 'expert evidence' .

Will need to book for DIA
Carried out diagnosis low oil pressure present. Checked valve chest for carbon build up – present
Removed under tray drained oil, removed sump inspected oil strainer – blocked. Removed injectors No3 nozzle leaking. Remove carbon build up on injector. Removed rocker and ancillary components. Removed pieces of carbon from valve chest. Clean injectors and bores with carbon cleaner. Extract nozzle washers (No3 jammed took 1 hour to remove. Clean all parts and replace those listed including return hose from fuel rail to fuel distributor (old one weeping and hard
Reassembled refitting injectors as per MFS. Partially remove oil pump and balancer unit to access obscured bolt on oil strainer. Replace strainer. Refit pump/balancer assy. Clean sump and mating surfaces. Refit sump replace oil filter. Refill engine oil. Charge battery refit start and run. Check for leaks o/k Road test till engine oil temp approx 90 degrees C Test oil pressure good approx 400kpa at 3000RPM Reset oil data. Updated PCM Cleared fault codes Run o/k"
Now, two years later - and after three services - it's now presented with a blown head gasket and Mazda N.Z. (through the local dealer) have refused to come to the party, saying that its because of the age and km's - which I just don't buy.Print out test plan

I am having Mazda CX5 2012 2.2L engine issues (currently sitting at the local dealer not starting, at least $8K to repair!) and wanting to gather a group of people to have a louder voice and hold Mazda NZ accountable.
How did you get on with civil action?
If you have Facebook, please join the group I have created on there so we can work together.
It would be great to hear from people who have current issues, who have had issues and Mazda hasn't come to the party, and people who had luck with Mazda being useful!

Any joy with Mazda NZ
Hi Tina
I've just been given a quote from local dealership of over $10k to repair head gasket and turbo on my 2014 cx5 diesel. The car has not overheated so can't understand how its blown a head gasket at only 125,000km. Have you had any joy with Mazda NZ with your repair??

Any advice??
Since my quote for over $10k to repair blown head gasket and replace turbocharger I've been back and forth with Mazda NZ who have now agreed to supply the parts for a basic head gasket repair and the control valve for the turbocharger (apparently this is the component that has failed and the turbocharger doesn't now need to be replaced) Mazda NZ said they had been in touch with the dealership and the previous estimate I received for labour, outwork and consumables was still accurate. I asked the dealership to confirm and they have now increased the price (extra 3 hours labour and extra $150 for outwork) so nearly 15% more, with no explanation. Does it take longer to replace a turbo control valve than replacing a turbocharger assembly?? Really unsure what to do as feel like I can't trust them

of two and a half months in my possession and then the head blew. What avenue did you get in touch with Mazda NZ through?
