Mitsubishi Triton Problems

My general rule of thumb is 160,000km but if it’s been well maintained the higher figure should be fine for something like a Triton.

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.

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.

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.

The rear springs have sagged, which is common on the Triton and some other Mitsubishi models. It could well be the cause of your problem. Most owners choose to fit uprated springs to their vehicles, particularly if they're carrying loads.

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.
