Fraught with problems?

Load of BS. The only reason they didn't come to the USA was because Mazda couldn't get the performance they wanted and meet the US emissions requirements at the same time. So unlike VW they didn't cheat.

None of which is relevant to the situation for the OP who is in Australia. And, living in a country area, would no doubt have been doing plenty of highway kilometres as well. Which would mitigate against any of those oil dilution issues.

I'm on my second CX5 diesel here without any significant engine related issues at all. A very very small number of people had the much hyped issues that have been reported.

To the OP - Take it to a Mazda dealer or a diesel specialist.

Your symptoms, which suggest the car is running fine with no nasty noises, except lacking power under load, sound very much like clogged diesel fuel filters. Regrettably, not an uncommon problem.

In fact that's more than a likely scenario especially in country areas, especially if you've filled up at a smaller fuel station where they don't put thru big volumes. And even with larger fuel stations, occasionally there is a contaminated batch, it's not uncommon to hear about them.

Probably you've picked up a bad batch of fuel, a new set of filters and possibly drain the tank out is likely to sort it. First step - tell them the symptoms and that you suspect a possible bad batch of fuel, and they will no doubt want to check your fuel flow rates and pressure.

Let us know how you go.

Wow! You sure called that one right Moonlighter. I guess my post was a load of BS like you said. Thanks for the keen insight into the reliability of this engine!

God forbid that I might try to offer some help and assistance based on my personal experience owning and driving CX5 diesels for about 4 years now.

How much experience driving one of them do you have??

We still dont know what the hell happened as the OP has not said why/what/ etc. All very vague indeed. We still dont seem to have anything close to the full story. And at the time of my post, we knew even less.

The CX5 continues to be one of the best selling mid size crossovers in this country, and is rated very highly by motoring organisations and motoring media.

Which it clearly wouldnt be if the diesel engine was "fraught with problems" as you stated.

Your comment still smells just as bad as when i originally called it.

What in terms of the full story do you think I am withholding? I can only give feedback on what I know of as facts.

To your previous questions asked about this

Mazda CX-5 Diesel: oil dilution/contamination

For Mazda CX-5 models with 2.2-litre 'SkyActiv-D' turbo-diesel engines, particulate matter could accumulate in the diesel particulate filter (DPF) if the vehicle was frequently used for short runs (due to insufficient heat being generated to burn the particulate matter). To stop the filter becoming clogged, diesel fuel could be discharged during the exhaust stroke to raise engine temperatures, but some diesel fuel could enter the oil sump and dilute/contaminate the engine oil. As a result, the oil level appeared to increase and Mazda issued a warning to owners that they should check the oil level every 1000 km or monthly.

Did you do that?

If the oil was diluted, the driver would receive warnings via:
The Master Warning Light (red triangle with exclamation mark);
The Check Engine Light; and/or
The Oil Light.

For engines that suffered damage due to diesel fuel contaminating the engine oil, the engines were replaced under warranty.

I had a issue with the engine early after purchase. The engine started but blew a massive amount of white smoke and all the above mentioned warning lights came on. I had it immediately towed to the dealer, and I was told it was an there was a fault in the particle filter in the exhaust sensor (something like that), the engine was not replaced. The matter was rectified and no further problems with that. I also recall mentioning that hiccup in my earlier posts somewhere?

Yes, I regularly (and have done in the past) check the oil level, not had a problem in that area either. I also know about the regular freeway driving needed to keep that particle filter working properly. I live rural and am on the freeway more than I wish to be so my car gets a get regular clean out.

I can't fill in the blanks If I don't have the information.

I do know this; I was told "the engine is gone", I was told "mazda will cover all the costs of a new engine". That's all the information I have at this stage until the paper work comes through, and If I'm left asking questions after that, than I'll call Mazda Australia for clarity.

@Moonlighter - if there are more questions you'd like to ask or to seek clarification on, then by all means ask away. If i don't know, I'll find out.

Well, Its good to hear its been taken care of.

Surely at some stage you might have asked the Mazda dealer questions along the following lines

- what exactly was the problem? "Engine is gone" would not be a satisfactory answer if it was my car.
- could it have been prevented?
- how could a catastrophic failure have been diagnosed just by a quick look and a mention of coolant spraying?
- And what was the cause or contributing factors, so as the owner you can take any necessary precautions in future?
- Has the underlying issue/fault been addressed through some change to the replacement engine? Or could it happen again?


Basically, what caused the failure and what could have been done to prevent it. Wouldnt you want to understand that?

The CX5 continues to be one of the best selling mid size crossovers in this country, and is rated very highly by motoring organisations and motoring media.

----------------------------

In Australia or in general? Because Mazda is a small automaker, and issues with cx5 have been well documented.

I see a lot more Ford/Toyota/Nissan CUVs in America.

I've also found most "reviews" are junk. CR, motortrend, whatever...they review brand new cars. Of course any brand new car will be pretty good. They mostly talk about gas mileage and fancy new tech options - Which is pretty useless to a car buyer, imo. Maybe useful if you lease and are not concerned with things like resale and reliability.

Sounds like you have a very good situation and will be taken care of in true Mazda fashion. Why would you be skeptical? Have you had a bad experience with this mechanic or dealership? ED

I said "in this country". Australia. Actually, i should have said that CX5 is THE best selling SUV in Australia, as you can see from the list below there are no other SUV's above it.

Here are the top 10 selling cars in Australia in 2016 from official VFACTS figures. (In brackets are comparison figures for all of 2015.)

Toyota HiLux – 42,104 (up from 35,161)
