Hi,
I have a 2012 Mazda CX5 (Diesel) that recently required an engine replacement.
It was outside of warranty, but as not 'fit for purpose', the engine was replaced by Mazda. It now has a 2 year warranty on the engine.
I've done 110,000kms on it.
I'm trying to determine whether it is more marketable now with this new motor and warranty, or if stating that would scare buyers off,
and I may as well just keep it with this 'new lease of life'?
Thanks
Mazda diesels…
That's about the 3rd I've heard of, and I don't sell Mazda
Yeah, apparently a "known problem", but with replacement, shouldn't recur.
you mean they fixed the defect on replacement engine / newer batch ?
@gabbo: @gabbo I've just had the same issue with my 2012 CX5 Diesel - engine failed (no oil pressure) and only done about 150k kms. How did you manage to get Mazda to agree to an engine replacement outside of warranty?
@robbov: Hi, this brings back memories.
Not sure, but it didn't take much convincing. I think i just used the right wording that implied I would take to VCAT etc as it was a known problem and that it didn't count as fit for purpose for 6 years use at the time. Might be a little trickier for you 11 years on though, but there may well be enough other info out there detailing the problem.
The front fell off.
There is a known problem with the 2012/13 CX-5 diesels, while Mazda didn't do a major recall on these models lots of engines were replaced in and out of warranty. There is a big thread on Whirlpool about it.
I'd hang on to it, I think a buyer would want to know more when you sell them a 2012 model with 2 years of warranty left on it.
Full Engine Replacement is actually a standard 'fix' for problems relating to many internal issues.
My local Mazda dealer has done many engine replacements on petrol Mazda 3s, for various problems, even though this is a simple car and engine. It is cheaper to ship a small box and do a full replacement than tear a modern engine down because the engines are 4 valve and many complexities which mean they seldom go back together as one might reasonably think. In short, maintaining the skills necessary to carry this out with a low enough failure rate on many engine types across many generations is not done in medium markets not just small ones like Oz.
Mazda aren't the only ones acting like this, but it goes to show how much of a commodity we accept cars are now/how they are considered an appliance with a finite life and 'too hard to fix'
Not sure if you are joking. Engines with 4 valves are too complex? Manufacturers like to just replace long engines? Not really on both counts. You aren't aussiecarguy on whirlpool are you?
Yep…keep it as resale would not be that good
So what component is failing in these things? I’m guessing the Turbo?
But you wouldn’t replace the whole donk just b/c the turbo failed, would you?
no. A bit of a google points to oil contamination
Oh? What’s that when it’s at home?
Edit; seems like Mazda had it so that diesel would get pumped into the particulate filter to aid in burn off of soot, but in some cases it would also leak into the sump oil and create dramas. Is that a case of bad design or is that something that would be difficult to foresee?
If Mazda fixed the underlying issue of oil dilution, I would keep the car. If they have replaced the engine with the same type and without a fix I would be tempted to sell the car and cut your losses.
Yep I believe oil dilution was the problem, sump oil mixing with diesel and depriving the engine of oil etc. We were worried our 2013 CX-5 might develop the problem but touchwood its been fine, its only done 80000 kms though.
Keep - good for probably another 110,000km then sell for low price if it's not ruined. This is if you dont need an upgrade/new car, why spend more.
Sell - if buyers do their research, then they should know of this problem, since it's fixed, it's a better deal
thanks for the response. It's exactly these competing ideas running through my mind that made me ask the internet for help, though. At least I can't be wrong either way.
I have the same problem now. First the exhaust pressure sensor was thought to be the problem and replaced ($750). Problem did not resolve. Now the issue is the turbo kit needs replacing to an estimate of $6k!!
Is it worth it in a 12.2012 CX5 that has done 130k km?
How much can you sell the car for with a blown turbo? Not very much. How much can you sell it for running? A lot more I'd guess.
What is that actual problem it has though? Does it have oil dilution issues like OP? If it does, the oil dilution can kill the turbo, as well as the engine. Can always get an oilsample done to check. Was your engine oil way above the full line?
My brither had a mazda 3 diesel after me saying don't buy it. Plenty on Google about them. The oil pick up sludges up. Maxda don't want to know about the cause they have no idea how to fix it.He isn't the type to fight for his rights sold it to a wrecker for $4000 eith a stuffed motor and bought a Corolla.. No oil goilg through equals no engine.

why engine fails at 110k ?
