Question 1

What air-bags are in the 2019 Mitsubishi Triton GLX?

Accepted Answer

According to website howsafeisyourcar.com.au, this version of the Triton has side air-bags in both the front and rear seats. Fitting side airbags was a great move by ute makers and reflects the fact that these vehicles are being used both as family cars and as company cars where OH and S requirements require a high safety rating.

Question 2

Engine issues in a 2009 Mitsubishi Triton diesel

Accepted Answer

This sounds like a case of a split fuel pick-up pipe in the fuel tank. When the tank is full, the split in the pick-up is covered by fuel, so the pump works normally at supplying the injectors with fuel. But when the level in the tank falls, the split is exposed and the fuel pump suddenly finds it’s much easier to suck air rather than fuel. And engines don’t run too well on just air. This could be interpreted by a scan-tool as a fuel leak, so a check of the tank’s pick-up tube seems like a good place to start looking. Any actual fuel leak large enough to cause this problem would, presumably, be visible, but it’s worth a check of the fuel rail and return lines as well. Failing that, you could have a dud sensor that is telling the computer there’s a fuel shortage and sending the car into limp-home mode to protect the engine (which would also explain the loss of power). It would also be worth checking to see that the new Suction Control Valve (SCV) is working properly, even though it's brand new.

Question 3

My 2019 Mitsubishi Triton won't reverse up an incline

Accepted Answer

If you had a loss of drive in every gear, the suspicion would be that the transmission is low on fluid or the torque converter is not working properly. But if it’s only reverse gear that is playing up, the chances are that the bands or clutch pack that locks the transmission into Reverse is allowing the gears inside the transmission to spin without actually transferring torque to the output shaft (and thence to the wheels). That said, there could be other internal problems that could cause this, so a visit to a transmission specialist is the best advice. Don’t delay it either, as continuing to drive the vehicle in its current state could do more damage to the transmission.

Question 4

Headlight problems with a 2018 Mitsubishi Triton

Accepted Answer

Diagnosing electrical problems remotely is a hiding to nowhere, but conventional wisdom says the wiring, earths and related switches are the first place to start. But modern vehicles also rely on body computers to control some of these functions, so that's worth a check, too. I can only hope you raised and logged this issue with Mitsubishi when it first started happening. If you did, you have what's called a pre-existing condition under the factory warranty terms. If the problem first surfaced five years ago, that would place the flickering occurring from about 2019. Which means, as a 2018 vehicle, it would have been covered by the Mitsubishi warranty. Even if the car subsequently runs out of warranty, a pre-existing condition is still legally required to be fixed by the car's manufacturer.

Question 5

What causes the DPF light to come on in my 2018 Mitsubishi Triton?

Accepted Answer

DPF technology is fast becoming the bane of turbo-diesel owners. The filter is designed to trap some of the nasty exhaust emissions of a diesel engine and then automatically burn them off at high temperature periodically, emptying the filter in the process. But way too often, this isn’t happening according to the script and filters are either clogging up, requiring a manual clean-out or, in extreme cases, complete replacement. This is possibly what’s happened to your car and explains why both the DPF and check-engine light have illuminated. It’s the car’s way of telling you you need to act. While it’s generally true that vehicles like yours that do more highway kilometres than city running have fewer DPF problems, all turbo-diesel fitted with such a filter have the potential to give trouble. An electronic scan of the Triton should show whether the DPF and check-engine light are related.

Question 6

Does the diesel 2010 Mitsubishi Triton use a timing belt or chain?

Accepted Answer

The 2.5-litre turbo-diesel engine fitted to the 2010 Triton uses a toothed rubber timing-belt which requires periodic replacement. Most mechanics reckon the belt should be changed every 100,000km and because of the design of the engine, the belt that drives the engine’s balance shafts should also be replaced at the same time.

Question 7

While I was fitting new side rails to my 2020 MR Triton I noticed the leaf springs. They are sagging!

Accepted Answer

The first thing to do is to ascertain whether the suspension has sagged or not. This can be measured quite simply and the results will tell you if the springs have lost tension or not. A canopy fitted to the Triton shouldn’t really make any appreciable difference to its ride height, nor should the world’s biggest dog, but it must be factored in. Neither should towing a box trailer have any long-term effect on a vehicle rated to tow anything up to 3100kg. If the springs have sagged, then it’s back to Mitsubishi as you have a legitimate warranty claim. If they’re within specification and you want more rear spring, there are plenty of aftermarket companies that can supply a spring that will lift the vehicle to the height you require. Be aware, though, that there are different limits on how high you can lift a vehicle depending on what state or territory you’re in, and major modification in this department may require an engineer to sign off on the changes.

Question 8

I have issues with the gearbox in my 2011 Triton 4X4 manual diesel. I  can change up through gears first to fifth but can't go from fourth to third.

Accepted Answer

This sounds like a classic case of worn synchromesh rings inside the gearbox. These rings are designed to make smooth, easy shifts between gears but as they wear (or even break) they lose that ability and the gears become difficult to change. It’s also common for this problem to be worse on downshifts compared with upshifts which is why you can shift all the way up to fifth, but have trouble coming back down through the gears. My money is on third-gear synchromesh being your problem. By shifting from fourth back to second and then third, you’re effectively `borrowing’ the second-gear synchromesh to soften the shift into third. Unfortunately, the fix is a gearbox rebuild. But before that, it would be worth changing the oil in the gearbox and checking out a gearbox additive that helps with shifting feel and smoothness. If that makes a difference, great, but you may still ultimately be looking at a new or rebuilt transmission. The other thing to know is whether the gearbox is reluctant to select reverse gear with the engine running. If it is, you might instead be dealing with a worn clutch which is much cheaper to replace.

Question 9

I have a Mitsubishi Triton MB with around 80,000km and full service history, after it was towed to the Mitsubishi dealership, they told me there was an issue with engine oil sludge...

Accepted Answer

Sludge build-up in oil is definitely an engine killer. But with a full and correct service history, this really shouldn’t happen. That it does, is possibly down to long service intervals (driven by consumer demand for less maintenance and down time) and possibly even the way the vehicle is used. If it’s worked hard (towing, for instance) in high ambient or dusty temperatures, then sludge can build up as a natural result. The way a modern turbo-diesel recirculates some of its exhaust gasses also mean soot can combine with oil vapours from the crankcase to cause a build-up of black gunge, and that’s not good either. I’d be keen to see what the oil analysis shows. If the oil was lacking some of the additives it needs to keep a diesel engine clean, then that may show up. If you can prove the service history to Mitsubishi’s satisfaction, I’d be asking for some kind of help in the cost of repairs. Whether or not the company plays ball is debatable, but it would definitely be worth a try with low mileage like this and documentation of correct servicing for all of its (short) life. If the vehicle is still under the factory warranty and you have a full service record for it, then it’s pretty clear you have a valid warranty claim, barring any negligence or mis-use on your part.

Question 10

My manual Mitsubishi Triton 2004 V6 petrol 4WD is having trouble coming out of neutral and going into gear...

Accepted Answer

In many cases like this, the clutch is the culprit. The problem appears as though it’s the gearbox at fault, but the reality is that it’s the clutch not releasing properly that is preventing you shifting gears cleanly and easily. When the clutch is either worn or out of adjustment, it can remain partly engaged even when your foot is fully on the clutch pedal. When that happens, the gears can be very difficult to select. Try this: The next time a gear becomes hard to select, turn the engine off and try it again. If the gear suddenly slips into place easily, then you’re probably looking at a worn clutch or one that is out of adjustment. Poor adjustment can be the result of low clutch fluid levels (in a vehicle with a hydraulic clutch) or a cable or linkage that is poorly adjusted. Your vehicle has a hydraulic clutch, so a leak from either the master cylinder, slave cylinder or any of the plumbing could have allowed the fluid level to drop to the point where the clutch is no longer disengaging fully. This is precisely where I’d start looking in your case. Remember, however, that while a worn clutch might be the most likely cause, that doesn’t rule out a problem with the transmission internally or a problem in the gear selector mechanism.
