Isuzu D-Max Problems

No car is perfect, but we've gathered everything relating to the Isuzu D-Max reliability here to help you decide if it's a smart buy.

Why doesn't the radio work in my 2016 Isuzu D-Max?

Answered by CarsGuide 24 Sep 2020

Blowing a major fuse suggests that your car has suffered a short-circuit somewhere within its kilometres of wiring. But a modern vehicle like your Isuzu will also have fuses protecting the various systems it needs to operate, so there’s a chance there’s a second fuse that protects the stereo system that has also blown when the problem occurred. Your owner’s manual should be able to identify the locations of the car’s various fuses. Don’t forget to replace them with a fuse of the correct amperage or you could cause more damage if the fuse ever needs to act as a circuit-breaker again (which is exactly the fuse’s role).

The other possibility is that the stereo unit itself has an internal fuse. Check around the rear of the unit (usually where the wiring for the speakers exits the stereo) and you might be able to locate the fuse in question. This is often the case in aftermarket stereo systems.

Is the Ford Ranger, Isuzu D-Max or VW Amarok best for towing a 2.8 tonne caravan?

Answered by CarsGuide 10 Sep 2020

Every all-new MY21 Isuzu D-Max and select current versions of the Amarok and Ranger offer a 3500kg towing capacity maximum - namely all Amarok V6 autos and all Rangers EXCEPT the 4x2 XL Single Cab Chassis Low-Rider 2.2 Diesel at the bottom of the Ford range, and the 4x4 Raptor Double Cab Pick-Up 2.0L Diesel at the very top (they're both 2500kg).

Least torquey is the D-Max at 450Nm, followed by the Ranger (2.2L 4-cyl: 385Nm, 3.2L 5-cyl: 470Nm and 2.0L twin-turbo 4-cyl: 500Nm) and Amarok (550Nm to 580Nm), meaning the Amarok will probably be the least challenged towing a 2.8-tonne caravan. But all three should suffice.

Please note, however, that Gross Combined Mass (GCM) tallies means that there are other weight factors that need to be considered before safely towing a 2.8-tonne caravan, even with a 3500kg ute. These include things like the ute's payload, heavy bull bars, sports bars and side steps, canopies and even the number of people travelling inside. And of course, a fully-equipped and laden caravan can easily exceed the stated tare mass.

We hope this helps.

Mitsubishi Triton 2016 or Isuzu D-Max 2015: Which one should I buy?

Answered by CarsGuide 16 May 2020

The D-Max is pretty well regarded in the trade for its ability to go the distance, but modern, common-rail diesel technology has shown that a vehicle with fewer kilometres is usually a better bet than one with more. Although they do an amazing job in terms of power, torque, towing and fuel economy, today’s turbo-diesels are pretty highly strung in some ways and really need their maintenance. And the older they get, the more attention they seem to need in terms of new injectors, filters and pumps.

A D-Max with those kilometres might be ready for a pretty big (and expensive) service, too, so make sure your first trip in it isn’t going to be to a workshop. Ultimately, price, condition and service history should steer your decision as they should in any second-hand vehicle purchase. I’d take a vehicle with 150,000km with a full service history over a 60,000km one with no service records.

What is the fuel economy like in the 2020 Isuzu D-Max?

Answered by CarsGuide 11 Apr 2020

The D-Max would be a pretty good choice of vehicle for this task. The three-litre engine is well regarded in the trade and because it’s a little larger (in capacity) than some of its competition, it also has a bit more torque which is great for towing. With a 3.5-tonne towing capacity, it’s also up with the best of them.

As far as fuel consumption goes, you need to bear in mind that even though it’s a four-cylinder diesel engine doing the work, you’re actually asking quite a lot of it when you’re towing a caravan at highway speeds. With that in mind, you can forget about the official combined figure of 7.8 litres per 100km. Bank on at least double that and maybe a bit more, especially if the caravan is a bigger one.

What car should I buy?

Answered by CarsGuide 28 Mar 2020

Boy, there’s a big difference between a Toyota CH-R and an Isuzu MU-X, Kathy. Rarely would both those models make it to the same short-list. In any case, the problem you’ll face is that buying any brand-new car involves waving goodbye to a large chunk of its residual value the same day you drive it home for the first time.

Who is advising you to get rid of the Toyota? I’ve seen plenty of V6 Toyotas with more than 300,000km showing and still going strong. And if the mileage does worry you, what about finding a low-kilometre second-hand Aurion and pocketing the many thousands of dollars you’ve saved by not buying a brand-new car? You already know you love the way the Aurion drives (and its reliability is beyond question) it’s big enough for grand-kids and it’ll handle its share of dirt-road action.

If you can’t find an Aurion, a V6 Camry is a good alternative, offering a similar level of interior space, performance and lots of value for money. A later-model example will also have side-curtain air-bags to protect rear-seat passengers. And when the word honesty is used in the context of cars, a Toyota Camry is one of the first mental images to appear.

Isuzu D-Max 2020: Updates

Answered by CarsGuide 22 Feb 2020

Car-makers tend to like to keep information like this a bit of a secret until the vehicle is officially launched, Michael. And since I can’t even find out when in the next 12 months the new D-Max is due to hit showrooms, it’s a bit tricky to answer your question. Word around the campfire, though, is that the new D-Max will indeed have an electronically locking rear differential, where previous models didn’t even have a limited-slip rear diff. So that’s good news.

Generally, you can’t engage a rear diff lock without engaging four-wheel-drive, but when it comes to what happens with traction-control at that point, the various manufacturers tend to go their own ways. Some will leave the traction-control active with the rear diff locked, others don’t. The former arrangement is generally regarded as the superior system for off-road traction, but it does potentially place more stress on the driveline. But which way Isuzu intends to jump in this regard is still anybody’s guess.

What do you recommend for towing a horse trailer and large draft-horse?

Answered by CarsGuide 15 Feb 2020

None of the vehicles you’ve listed are exactly low-maintenance units. They all have complex all-wheel-drive drivelines (which will be appreciated when towing a heavy trailer across a wet showground) and they use the latest common-rail diesel technology which is fairly intolerant of poor servicing.

As for a power tailgate on a ute, I’m afraid you’re out of luck. But some of the wagon versions of these vehicles can be optioned with powered tailgates. The catch there is that these vehicles use coil sprung rear axles (as opposed to the leaf-sprung ute versions) so they’re not as adept at towing. The Toyota Fortuner, for instance can’t match the HiLux’s 3.5-tonne limit and makes do with 2800kg; not enough for your requirements. The Ford Everest (based on the Ranger) is a little better at 3000kg, but still trails the Ranger’s 3500kg towing capacity and is right on your self-imposed minimum.

Isuzu D-Max 2010: Do the front wheel bearings need repacking every 30,000 kms?

Answered by CarsGuide 21 Dec 2019

From experience, vehicles like the D-Max (and many others) are very hard on front wheel bearings. But you’re right, that’s really because the majority of them are all-wheel-drive while yours is rear-drive. So I would imagine wheel-bearing service intervals would be a lot longer than 30,000km.

The problem with four-wheel-drives is that the front wheels are being asked to do an awful lot. As well as steering the vehicle, they also have torque going to them from the engine. Also, since these vehicles tend to be used off-road, the wheels and bearings are routinely dunked in silty or even salty water. That shortens the lifespan of any components. The heavy turbo-diesel engine sitting over the front wheels also adds to wear in these cars, and could be part of the reason for such regular maintenance.

Or, it may simply be that Isuzu has made a blanket decision that all D-Maxes, regardless of driveline, have their wheel bearings repacked every 30,000km. It certainly won’t hurt to have the bearings inspected every 30,000km, but I’d be very surprised if they needed repacking every time. Some of these vehicles also use a sealed-for-life bearing and require replacement rather than repacking.

The difference would be if your vehicle was still under warranty (which, being a 2010 model, it’s not) at which point you’d need to stick with the factory service schedule to keep your warranty intact.
