2019 Mazda CX5 2.2D Sport Nav + AWD Auto - 2019 Mazda CX5- engine issues - Patrick Dorrian

Just wondering if anyone has anything sensible to say about the later versions of these, has the issues with sump filling / DPF been resolved? Do the facelifted cars ( post2019) still report as having the same issues as the pre 2017 models?

Anyone got a 2019 2.2D CX5 in ^^^ spec and got anything positive / negative to say about it?

If buying new and being used in a manner which will keep DPF issues at bay, why not?. If buying used from someone you know has used it in a manner which will keep those DPF issues at bay, maybe but I'd still be wary.

Any other scenario?, you shouldn't go anywhere near it because you just don't know what is round the corner.

TBH, you should probably be wary of most modern diesels (except perhaps the Honda 1.6 DTEC), but the Mazda more than most.

Wouldn’t touch it, I notice our local Mazda dealer themselves won’t stock used diesel Mazda’s beyond the initial manufacturer warranty term, this tells me all I need to know regarding whether they’ve finally fixed the 2.2 skyactiv D motor. The 2.0 petrol may be lacking in torque but it’s reliable and quieter plus not that much worse on fuel. The reputation this engine has also guarantees heavier depreciation, the trade know how unreliable they can be and they price this risk in when bidding on them so expect to take a bath on it when you come to resell should you decide to jump in.

If the petrol is unsuitable due to needing to tow or you simply want more oomph then look at a Honda CRV 1.6 DTEC Twin turbo AWD or a Toyota RAV 4 2.5 Hybrid, good well cared for examples of either will easily outlast the Mazda diesel. Just check the towing weight of the hybrid if this is an issue.

Cheers both - that explains why most of the stock is private or independent. I did wonder wtf was up with that!

The RAV was on the original list although the spec I'd want is nudging 27k at the moment ... I'll park it until next year and buy what I originally test drove and liked. I think as an all round only car they are superb.

My 2017 Mazda 2.2d is super fun to drive , totally reliable and best car I've owned.

Nothing other than a mirror has had to be done.

Oil change twice a year, never interrupt a Regen , not too many short trips.

I'm sure that there must be many - a majority - of Mazda diesel owners who have had no problems.

However, as others have pointed out, the failures are a just a bit too common to ignore when buying second-hand and are expensive to fix. Mazda has never budged an inch when it comes to admitting there is a design fault with these engines, which it seems are less tolerant of certain driving habits than many other makes.

As others here must be bored with hearing, I am very satisfied indeed with my CX-5 petrol, though I admit the extra poke of a diesel engine would make it much more exciting to drive.

You mention that it’s important not to interrupt a regen.

How can I explain this to a friend who has one if these and has never noticed the car performing a regen ?

Several clues (and hence why it's a good idea to get to know a diesel car by what it does / how it responds) which I got from a quick interwebs serach (and me annotating it):

  • Engine note change (higher than usual for the conditions).
  • Cooling fans running (when you wouldn't normall expect them to).
  • A slight increase in fuel consumption (compared to usual - check via the trip computer).
  • Increased idle speed.
  • Deactivation of automatic Stop/Start.
  • A hot, acrid smell from the exhaust. This may also be felt if you open the door (coming from underneath the car) when you've pulled up to stop before switching the engine off either leave it on (idling) or keep driving until all of the above disappear.

Essentially the diesel engine is doing their sort-of equivalent of an 'Italian tune-up' via injecting some fuel into the DPF and burning it to burn off any residual particulates to clear the DPF.

If it gets interrupted, persumably some of the particules will stick and won't be able to be removed by future active regens, possibly only via a forced regen at the delership /specialist, and not awlays, hence why a reasonable amount of the time the who unit has to be replaced.

Unfortunately car manufacturers don't make it easy to determine if an active regen is in progress / has finished, as it apparently is for HGV drivers, who presumably have an indicator light.

It would have been nice for a relatively inexpensive system of that sort to be fitted to cars and vans, even better (if possible) for one also with some kind of coundown timer (to completion) or percentage complete display.

Quite riduculous that car makers haven't fitted even a warning light to let one know a regen is underway.

With my present truck every few months the warning light will come on and regen last for about 20 minutes, the exhaust temp raises a lot you can smell and feel the heat, couple of times i've had to cancel regen (switch on dash for this) for safety reasons, and a couple of times over the last nearly 5 years i've made minor diversions to allow the regen to complete.

It also has a static regen switch, only needs to be used in the event several regens were cancelled and the vehicle would request such an action in necessary...the idea being to park somewhere safe and the vehicle would self regenerate whilst parked, in practice this has never been needed.

Other makes of trucks have slightly different approaches, but all i've driven in recent years allow the driver to have some discretion.

None of this is hard to understand, why do car makers assume their customers are clueless, the only maker i know of in car world to have fitted something similar to that found in trucks is Toyota on their Landcruisers.

As for this thread, no i wouldn't trust the maker in question to have found the magic formula, have they offered an extention to the warranty up to 7 or more years? ...hold the front page maker puts money where mouth is!

Madness to buy an out of warranty diesel mazda

The local mazda dealership does not want them, even in part exchange they are sent straight to auction.

There are lots of alternative makes and models available, dont buy a mazda diesel

Perhaps because they are?

Indeed - most people barely do any research (other than what the cars look like or perhaps the performance).

One piece of advice I have used throughout my car-owning life that I got from here (either from a fellow Backroomer or via HJ himself one way or the other) is to never, ever buy a new car that has just changed design to a decent extent - wait a couple of years or so until the vast majority of design / production flaws have emerged and have been (hopefully) resolved.

I think that piece if sound advice is increasingly relevant today, given how many cars are R&Ded in a far shorter period than in the past and often incorporate a lot of new, highly complex technology - often relating to safety and emissions, and especially as regards electronics and software.

My dear old dad just parted with a significant amount of cash (especially compared to what he paid for the previous one and where he'll likely give up driving in 5 years or less, meaning he'll take a BIG depreciation hit, especially when accounting for the30%+ price bump in second hand values at the moment) for a car he did no research on (or any alternatives), a short test drive and now doesn't like (a LOT) and has found it very difficult to get used to.

His dealership just invited him to a 'sales event' where they presumably persuaded him to part with his old car rather than spend a small fraction (likely 10%) to fix the minor issues it had.

As regards issues like modern diesels in DPF, fuel dilution and turbo problems, I'd bet that most drivers have little to no knowledge or understanding of them, and the only reason they are currently dropping buying diesels in big numbers is because they are being told they likely will be legislated out or subsject to significant financial penalties for use such as in (present or future) ULEZs.

Of course, that means that huge amounts of likely otherwise decent cars will either be scrapped or disporportionally end up in areas not served by such measures, plus people getting rid of them for new(er) petrol / hybrid / EV cars will be seriously out of pocket and reasonably often (like my dad) not liking the ownership experience of the replacement, precisely because they've done little to no research before changing.

<< ...huge amounts of likely otherwise decent cars will either be sc***ped ... >>

That swear-filter really is a clumsy instrument ! It doesn't bother to distinguish between real words and bits of included words. Reminds me of a (early, about 1970) computer search my one-time boss did - it reported 'urea' in the American Bureau of Standards.

Very good advice to wait a year or two for a new model of car to sort out any issues.
This was very true with the VW Passat and rebadged Skoda Superb, most of the common issues where from models between 2015-17 when the Mark 3 was introduced, since then the issues have reduced.

Same is true of the latest Octavia, alot of the earlier issues are slowly being sorted for new cars although sadly too many still remain which suggests VAG are not doing their due diligence in terms of new tech.
Maybe worth considering an Octavia in 2024 when they have hopefully sorted out a few more of the common issues.

Of course none of this applies to Land Rover who make unreliable highly sought after vehicles and have no need to be reliable.

My FIL did the same many years ago. I suggested the '70s Austin Princess may suit him. He went and bought one! He'd have the seat at maximum height in it s most forward position, because he complained he couldn't see the front of the bonnet. Got rid of it after a few months and bought a Volvo 360 from the garage a few doors away.

I bought a Princess many years later to cater for my increasing brood, perfect for my time and circumstances.
