Isuzu Problems

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

Does the 2014 Isuzu D-Max have a DPF filter in the exhaust system?

Answered by CarsGuide 7 Dec 2021

Isuzu switched to a new, Euro 5-compliant engine for the D-Max ute in 2017. To meet the stricter Euro 5 emissions requirements, a DPF was fitted. But D-Maxes before that time do not have a DPF fitted. On that basis, your car will not have a DPF.

Given the problems experienced by owners of DPF-equipped vehicles (not just Isuzus) this is one of the things that has made the older D-Max such a popular second-hand buy.

Will a 2006 Isuzu nudge bar fit on my new 2021 Isuzu D-Max.

Answered by CarsGuide 3 Nov 2021

Almost certainly not. Unless there’s some strange quirk of manufacturing that allows the mounting points to magically line up, the current Isuzu D-Max is an all-new design, compared even to the most recent predecessor, let alone the model from 2006. The 2006 D-Max shared a lot of its architecture and engineering with the Holden Rodeo and later Colorado, while the new D-Max is a joint venture with Mazda and forms the basis of that company’s BT-50 range of utes.

You may be able to engineer a set of adaptors to mount the early nudge-bar to the later vehicle, but at some point it’ll get messy and simply not worth the time and money investment compared with buying a nudge-bar designed specifically for a 2021 D-Max. There’s also the issue of whether the old nudge-bar design would be compatible with the air-bag system of the new Isuzu. Again, almost certainly not is the short answer.

What car should I get to tow a 22-foot caravan around Australia?

Answered by CarsGuide 22 Sep 2021

I wouldn’t be concerned about the cylinder configuration of a particular engine. What’s more important is how much power and torque that engine makes, and how towing-friendly that power delivery is. By which we mean how smooth and flexible is the delivery. What you don’t want is a peaky engine that needs to be revved before it delivers the good as that puts a strain on everything and make the vehicle tricky and unpleasant to drive.

The good news is that all the vehicles you’ve nominated have good, solid powerplants that are well suited to towing a caravan. Modern turbo-diesels – especially with an automatic transmission – are ideal for this task.

What you should go for, however, is the vehicle with the highest towing rating. In this case, that’s any of the Grand Cherokee, MU-X or older Discovery, all of which have variants that can handle a towed load of 3.5 tonnes. The Everest is almost as good with 3.1 tonne, but only almost. The problem is that the van you’ve nominated can easily weigh between 2.2 and 2.8 tonnes which, with a 3.1-tonne limit, leaves you very little headroom for water tanks and camping gear. You’d be amazed at how much a fully loaded caravan weighs, so don’t rely on the brochure, load the van and take it to a weighbridge to make sure the vehicle you have can legally tow it.

What can I do after the engine cover arms of my 2019 Isuzu D-Max broke after being serviced?

Answered by CarsGuide 8 Sep 2021

Warranty or not, if the workshop that serviced the car broke the cover, surely it’s up to that business to fix it. Separate to that is the fact that the car is still well and truly under warranty, so that makes the problem Isuzu’s to some extent, also.

To be honest, these plastic covers are one of the more useless additions to modern cars and really only serve to make the underbonnet area look a bit neater when you open the bonnet. In fact, they allow packaging engineers to be a bit lazy as they can cover a messy layout. The best advice is to get hold of a new cover under Isuzu’s warranty and store it in the shed. Then, when you’re ready to sell the car, fit the still-new cover so it looks neat and tidy for would-be buyers. The vehicle will run fine without the cover.

What 4WD should I buy for towing?

Answered by CarsGuide 23 Jul 2021

To get a vehicle with meaningful (as opposed to a theoretical) towing ability of 2.5 tonnes, you really need to shop for a relatively late-model dual-cab 4X4 ute. The reason for that is that many vehicles that claim a 2.5-tonne limit in the brochure fail to explain that there’s also a Gross Vehicle Combination Mass in play and, by the time you’ve added passengers, gear and a full tank of fuel to the towing vehicle, there might not be much of that GCM to devote to a towed load.

Going for a vehicle with 3000kg or even 35000kg towing capacity in the first place is a good way to ensure you do accidentally start driving around in an overloaded vehicle with all the legal and insurance connotations that involves.

A lot of the current shape dual-cab utes fall within your budget on a second-hand basis, but there are caveats. Make sure you only buy a ute with a full service history. Some of these vehicles were worked hard by their original owners, so be very careful before handing over the cash. Avoid ex-mine fleet vehicles and don’t be afraid to buy a base-model vehicle if it offers better value. Even a single-cab version of these utes will be a lot cheaper than the dual-cab and, if you don’t need the rear seat, are often a more practical solution. Makes and models include the Ford Ranger, Toyota HiLux, Mazda BT50, Mitsubishi Triton and Isuzu D-Max. For real value for money, vehicles like the Ssangyong Musso can tow 3.5 tonnes, are well equipped and can be had for less than $35,000 drive-away, brand-new. That also gets you a seven-year factory warranty. All of these options are available with the automatic transmission you want and, indeed, this is the best option for a tow vehicle.

Why doesn't my Android connect via Bluetooth in my 2017 Isuzu D-Max?

Answered by CarsGuide 8 Jul 2021

This topic has been a red-hot one for many years now. It seems a lot of car-makers can’t seem to get it right when it comes to specifying a Bluetooth system that will work for Australian customers. Toyota had all sorts of crazy issues with the Bluetooth in its vehicles of a few years ago, although recent experience suggests that is now sorted.

I’ve not heard of the Isuzu D-Max as a problem child specifically, but it doesn’t surprise me to hear that you’re having difficulties. There’s a theory that some Bluetooth systems simply don’t play well with some makes and models of phones, and that could be what’s happening to you. A quick check would be to find a friend with an iPhone and see if that will work better in your car. That would at least rule out a blanket problem with the unit in your car.

Is it worth waiting for the new Isuzu MU-X?

Answered by CarsGuide 15 Apr 2021

When the new D-Max arrived in 2020, the big improvements included a step up in standard equipment and a big leap forward in refinement and ride quality. The engine and driveline, however, was carried over from the previous model, so performance and driveability were similar.

With that in mind, you can probably expect the all-new MU-X to offer a similar hike in standard equipment terms. But unlike the D-Max with its rear leaf springs, the MU-X already features coil springs all around, so there may not be quite the same boost to refinement or ride quality. That said, it’s unlikely Isuzu would go backwards in this department. If you can live without the creature comforts, then a run-out deal on the old model seems like a pretty good idea. It really all depends on how much importance you place on having the latest and greatest.

Why wont the RPM of my 2015 Isuzu D-Max go higher than 2500?

Answered by CarsGuide 9 Oct 2020

The first thought here is that you’re dealing with a dodgy throttle-position sensor or some other sensor that is giving the on-board computer a reason not to exceed 2500rpm. Or tricking the computer into thinking that the engine is spinning faster than it really is. Have you had the vehicle scanned? It’s a cheap way of reducing a lot of the guesswork in a case like this.

Like any engine, of course, a turbo-diesel won’t rev beyond the speed that the fuel supply can support. You say you’ve changed the fuel filter, but have you checked the pump pressure and the fuel-delivery rate? A problem with the pump or fuel lines could easily produce the symptoms you have. You could even have a blocked fuel pick-up in the tank.

The other problem with modern turbo-diesels is that they are prone to clogging their intake systems with a black gunk that is a by-product of soot and oil mist from the vehicle’s exhaust-gas recirculation and crankcase-ventilation systems respectively. This black, ooze can sometimes almost completely block the intake path for air entering the engine and will cause all sorts of dramas, including the one you’re seeing.

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.

Why is my 2017 Isuzu MU-X struggling to make power?

Answered by CarsGuide 16 Sep 2020

If the new clutch helped the vehicle climb hills, then I dare say that was money well spent. As for noises from the engine under load, I’m afraid that’s a job for somebody on the spot who can listen to the vehicle and make an assessment. The noise could be major internal problems or it could be something as simple as a loose heat shield under the car. Even a loose or worn engine mount can create all sorts of mysterious and expensive-sounding noises and rattles.

Don’t forget, your vehicle came with a five-year factory warranty, so a major failure that is not the result of mis-use or general wear and tear (provided the vehicle has travelled less than 130,000km) is still covered by Isuzu.
