Mitsubishi Triton Problems

The new car warranty was for five years or 130,000km, so while it still meets the time part of the deal it's beyond the kilometer limit. Any extended warranty you have would have come from the dealer rather than Mitsubishi, so you would have to read the warranty conditions to know if the turbo seals are covered. I would expect they are if they fail because of being faulty.

Without knowing more about the vibration you report it's hard to diagnose a cause, but we note that other Triton owners complain about a vibration on takeoff, which I suspect could be what you experienced. If it is I understand the problem has been referred to Mitsubishi in Japan for a fix, and that it could be a result of the changes made to the rear suspension on that model. We can't say it will get worse with age or when towing, but if you are concerned about it then you perhaps you shouldn't buy the car.

I reckon your mechanic is on the money with the injectors. Worn injectors are a common problem on common-rail diesels; it's something that affects most brands

You first need to decide the level of off-roading you will be doing because that will determine if you need a four-wheel drive or you only need an all-wheel drive SUV. From what you have told us I suspect that an SUV, such as a Kia Sorento, Toyota Kluger, or a Nissan X-Trail would be the best all-round vehicle for you. All of those would fit your budget, they will all go off-road to a reasonable degree, and they're all reliable. The Mitsubishi Triton is a hard-riding ute, which I don't think is what you want, but the Suzuki Grand Vitara is a good vehicle and would also fit your needs.

If the suction control valve is worn or there is contamination present the fuel pressure will be affected and so will the drivability as a consequence. The car will sometimes go into limp home mode when this happens. It is a relatively common complaint on common-rail diesels, and the only thing to do is to replace the valve.

Rust protection is usually a dealer option rather than a factory one, so you need to check the warranty document for the product to see what is covered. With regard to the clutch slave cylinder you need to establish how sand got into it. Was it because of a faulty or damaged seal etc.? Having done that you could have grounds to claim on the warranty, but before you know why the sand was able to get in you really don't anything to back up a warranty claim.

It could be a worn synchro, but I would suspect it’s more likely to be a worn clutch. Have a mechanic check it for you.

Driving through puddles is not a problem, but driving through a creek or river could be problematic depending on the depth of the water. This is a case of you say, they say. I would suggest you sit down with your dealer and ask him to show you evidence of the water ingress they claim has occurred. Then try and reach an agreement with them and the car company on what they might do for you.

We haven't had any other reports of the same problem. The only thing you can do at this stage is to work with the dealer in trying to a remedy for the problem. Press him to enlist the help of Mitsubishi head office.

The claimed average for the Triton diesel is 9.6 L/100 km, the claimed consumption for urban driving is 11.9 L/100 km, for highway/country driving it’s 8.3 L/100 km. That, of course, is the result of a laboratory test, not a real world one, so you have to allow for some variation.

You also have to allow for some variation due to loading, driving style, road conditions, tyres and the general state of the car. I’d recommend that you keep accurate records of the fuel used so you have the data to present to the dealer, and to Mitsubishi. If your data shows the car is not performing as they claim it should ask them to rectify it. Should they refuse approach the consumer affairs people with a claim that the vehicle as supplied to you is not what was represented to you.
