Mazda Problems

Small all-wheel drive hatchbacks are rare in Australia, as only a comparatively tiny number of people live in the sort of environments that require the added traction and surety that AWD provides.

Also, most Australian consumers seeking AWD tend to go for smaller SUVs, since they are easier to get in and out of, offer a higher seating position and generally enjoy better resale values. On the flipside, SUVs cost more to buy and run, are not as stable at increased speeds due to their higher centre of gravity and are larger to manoeuvre in tighter parking spots than a small hatchback.

The Subaru Impreza remains the least expensive small AWD hatchback you can buy new, as well as the sole mainstream-branded model starting at under $30,000.

However, while the latest-generation Impreza launched in 2016 it's a huge improvement over previous iterations (with service intervals finally extended  to 12 months/12,500km), there are a few more compelling alternatives in small crossovers – that is, the in-between segment between small cars and SUVs; they boast a few extra centimetres of ground clearance without the bulk. Note only a few crossovers offer AWD as an option.

A recent stint in the new Impreza-derived XV 2.0L Hybrid revealed it to be a powerful and economical crossover with excellent handling and road-holding capabilities. The same applies to the Mazda3-based CX-30 AWD, the Toyota C-HR 1.2L-turbo AWD and Volkswagen T-Roc 140TSI 4Motion - though none are as frugal as the Subaru.

If you're not sold on the idea of an crossover AWD and prefer a small AWD hatchback, then your only other option is to stretch to premium European hatchbacks like the Mercedes-Benz A250 4Matic, BMW M135i xDrive, Audi A3 quattro and Volkswagen Golf R. But all generally cost upwards of $60,000 drive-away - and that's before some of the more desirable options fitted.

Finally, unless you are travelling hundreds of kilometres ever week, there is probably no benefit choosing diesel over petrol, as the former fuel is dirtier for the environment and not as quiet and refined as the latter. Additionally, diesels are falling out of favour with buyers due to their harmful emissions, and most companies are switching to petrol/electric hybrids as a solution. Again, this means the Subaru XV Hybrid AWD.

A long response we know, Jan, but we hope this helps.

Clearly water is getting into the car and causing your problem, so the trick is to find where it’s getting in. For start, have a feel around the seats and carpets to see if you can feel a damp patch. That will help narrow down the entry point. So will locking the car up on a warm day and noting which windows fog up.

Once you’ve done that you can start looking closely at all the rubber seals around the windows and doors as these are a likely culprit. Believe it or not, even a simple leaf or twig stuck to the rubber sealing surface can allow rainwater in, and any little nick or tear in the rubber can do likewise. It might sound basic, but are all the windows closing properly? Does the car have a sunroof, as these are notorious for letting water in even when they’re closed?

If you can find a volunteer, have them sit in the car while you take a garden hose to it. If the leak is a bad one, they might be able to spot it. Other times, though, the car needs to be moving for the water to be forced or even sucked in.

You should also check the level of coolant in your radiator or overflow bottle. If the heater matrix inside the car is leaking coolant, you’ll get the same symptoms over time. The clue there is that if the heater is leaking, the level in the radiator will fall.

Thanks for getting in touch with us. Our first thought was for you to consider a Mazda 6 wagon from Japan, since it is one of the few new wagons left on offer within your price range, is economical and reliable, a pleasure to drive and low enough (at 1480mm) for your garage situation. But it doesn't quite meet all your requirements in that it hasn't much ground clearance (at just 125mm) and back-seat legroom isn't great. It's worth remembering that the 6 wagon is 80mm shorter in wheelbase - the distance between the front and rear wheels - than the corresponding sedan version. It's a bit tight in there.

Alternatively, you might want to consider the just-discontinued Holden ZB Commodore wagon or Ford Mondeo wagon, as both offer substantially more rear-seat legroom than the Mazda 6 wagon, as well as the choice of a turbo-petrol or turbo-diesel engines. These are European-sourced models (Germany and Spain respectively), with big boots and towing-friendly torquey engines. However, again, low ground clearances might be an issue here as well.

So, our advice is to measure your garage roof and see if either of the medium SUVs listed below can fit, because if they do, then these would be the absolutely ideal vehicles for your need.

The better of the two, for its overall quiet refinement, all-weather all-wheel-drive grip and excellent all-round vision is the Subaru Forester from Japan. It ticks all your boxes in terms of needs and suitability, while providing heaps of ground clearance at 220mm. Plus it offers excellent standard safety kit, economy, reliability and resale, as well as decent performance. Just know that it stands 1730mm tall. If that fits, then find yourself a demo at $35,000 and enjoy one of the best family-car buys at any price available today.

Then there our second favourite, the wildly-popular Toyota RAV4, also from Japan. Much of what we said about the Forester applies here too, except it is front-wheel drive rather than AWD at your price point. There is a RAV AWD but it is a hybrid AWD system that takes the price into the mid-$40,000 region, so that's out of contention. The base RAV4 2WD also has a smaller engine (at 2.0-litres) than the Subaru, but it is equally response and agile. Where the RAV4 eclipses the Forester from your perspective is height – it is shorter at 1685mm high, while still allowing 195mm ground clearance.

Both Japanese SUVs are huge inside, with loads of space to boot. If their height doesn't end up being a problem, then know that either will provide many years of faultless, reliable, economical and enjoyable service. Good luck, we hope this helps. 

Despite the Mazda 3 growing in size over the years (and gaining about 100kg depending on the model and specification) the boot size hasn’t improved in the 11 years between the models you’ve asked about.

The 2007 Mazda 3 sedan had a boot measuring 416 litres, while its 2018 opposite number could fit eight litres less with a total of 408 litres. The 2018 hatchback had even less luggage capacity with just 308 litres.

As an aside, when comparing boot sizes, it’s important to know the exact method the manufacturer has used to arrive at the figure in the brochure. There are different methods and they have a huge effect on the outcome. Presumably, Mazda hasn’t changed its measurement method over the years, so the comparison in this case stands.

We contacted Mazda specifically on your behalf, and its response is that only some grades have an engine cover. Ones that do not are the base XT, while the XTR and GT versions do have a cover. We hope this helps.

The symptoms you’re experiencing all sound like they have something to do with the body computer(s) on the car. So it’s conceivable that a bad batch of computers on Mazda’s production line could affect more than one car. And if that’s the case, you’ve just been unlucky. That said, Mazda is not exactly a stranger to body computer glitches, and Mazda 3 built between 2015 and 2017 were, in fact, recalled to fix just such a problem that was affecting the operation of the windscreen wipers.

If you’re unhappy with Mazda’s approach, you can contact the ACCC to try to organise a resolution. But if the second car is only throwing up bogus tyre-pressure alerts and hasn’t started having other problems yet, then you should give Mazda the chance to put it right. The other problems may never develop, but if they do, I reckon you’d have a decent moral case for getting your money back. That said, Australia doesn’t have the `lemon laws’ that, say, the USA, has so getting a refund is not a simple matter.

The Mazda 2 is a great choice. It has always been towards the front of the small hatchbacks when it comes to safety and is definitely one of the better littlies to actually drive, too.

Mazda facelifted the 2 in 2017 and took the opportunity to add blind-spot monitoring and rear-cross traffic alert to the vehicle at that point in time. The catch is that the safety tech was only standard on the more expensive models and both the Neo and Maxx versions missed out. You could option that package when you ordered a Neo or Maxx, but it cost extra, and some people didn’t see the value in it.

So, if you’re shopping for a second-hand Mazda 2 Neo or Maxx, make sure you check carefully that the options you want are fitted. If you’re buying brand-new, no problem, because the most recent upgrade to the 2 saw rear-cross traffic alert and blind-sport monitoring become standard across the range. Lane-departure warning and lane-keep assist also became standard at that time. Significantly, autonomous emergency braking was standard on all Mazda 2s built after the 2017 facelift, making the car a very safe package.

As for alternatives, the world is your oyster with $30,000 in your pocket. There are lots of really good, safe cars out there in that price bracket, but, again, the Mazda 2 should definitely be on your short-list.

US-based Bose is certainly working on a system that will cancel out noise in cars. At the moment, though, it’s not available and will probably only be fitted to brand-new cars as standard equipment. At first anyway, because tech like this has a habit of tricking down to the aftermarket. However, that’s not much help to you right now.

Wearing noise-cancelling headphones is not practical (or sensible, or legal) so you need to look at an old-school solution such as the tyres you mentioned or stripping the car’s interior and fitting a noise-suppressing matting under the carpet and inside the doors. If it’s any consolation, it’s not your imagination; Mazdas for the last 20 years have been harshly criticised for their interior noise levels when the competition seems to do it better.

Ironically, active noise cancellation technology as proposed by Bose is not to tame mechanically noisy cars, but to remove wind and road noise from electric cars which are otherwise so quiet, these secondary noises become a big nuisance.

You’ll almost certainly cause the dashboard to present you with a `check engine’ warning light, Brett, as blocking off the Exhaust Gas Recirculation (EGR) valve is an intrinsic part of the vehicle’s emission controls. Having the vehicle go into limp-home mode is a very real possibility as well.

But perhaps more financially damaging would be the consequences of being caught driving the vehicle with a blocked-off EGR. The government takes a very dim view of anybody disabling any part of a car’s emission controls and the fines for doing so can be huge.

However, I know this is a real issue for many owners of modern turbo-diesels. The problem is that soot from the exhaust gas is mixed with oily fumes from the crankcase and then ingested by the engine as part of keeping emissions down. But the mixture of oil and soot can form a black gunge that can block the intake system. Really, though, blocking the EGR is a fairly clumsy way of getting around this. My advice would be to fit an oil separator which should keep the oily mist from the crankcase ventilation out of the equation.

If you’re happy with the Mazda 6 wagon – and it sounds like you are - then there’s a good case for sticking with the Mazda brand. And if that’s the case, the next thing to consider is which model and body style. Given your requirement for a car that is easier to get in and out of, I reckon a mid-sized SUV might make the most sense since it’s footprint will be similar to the Mazda 6 you have now, but it sits you higher and more upright. On that basis, the Mazda CX-5 seems the natural choice.

If you go for the petrol-engined Touring model, you’ll get all-wheel-drive for extra grip and safety as well as keyless entry and start where you can open the vehicle and start the engine without even taking the key from your pocket. Very convenient. If you can afford a little more, the GT model gets you the powered front seats you need and these even have a memory function that will automatically adjust them to either your or your husband’s preferred settings as a one-button job. Again, very convenient. The GT model also get a powered tailgate which was also on your must-have list. About the only thing missing is the full-sized spare wheel, and all Mazda CX-5s use a space-saver spare. But be honest, are you going to change a flat tyre yourself, or call roadside assistance? And when was the last time you experienced a flat tyre anyway?
