Mitsubishi Triton Problems

Sorry. Clutches, like brakes and tyres, are always regarded as wear-and-tear items. It's the same for new cars. Without doubting your driving, many people are very hard on their cars.

It would seem that there is an electronic issue with your car; the challenge for the dealer is to find the cause so it can be fixed. The car is still in warranty so you should be pressing the dealer and Mitsubishi to fix it, and fast. Go back to the dealer and find out when the Mitsubishi rep will be checking your car. If you get no satisfaction from the dealer, go directly to Mitsubishi's customer assistance people (Ph: 1300 13 12 11) and explain your problem to them.

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 would be looking at the fuel supply, the filters, fuel pump, and the fuel itself. If the performance generally has dropped off I would also be looking at the turbocharger.

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.

There have been other reports of rust in the Triton. When Mitsubishi was approached with a similar problem in 2015, the company offered the owner a full inspection and a Mitsubishi representative present and the promise that it would be rectified in line with the company's warranty. On that basis I would suggest you contact Mitsubishi headquarters direct and request similar action on your vehicle.

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.

You don't say if it's two-door cab-chassis, dual-cab ute, diesel, V6, GLX etc. so it will be a rough guide only. $7500 to $10,000 is about the best we could give you.

I would be looking at the injectors first. Worn injectors are common in modern common-rail diesel engines; it could also be a sticking injector. You could also check the low and high-pressure fuel systems.
