Mitsubishi Triton Problems

Mitsubishi quotes a combined average of 10.9 L/100 km for the 2.4-litre dual-cab Triton. Around town they claim 13.9 L/100 km and on the highway 9.1 L/100 km. It’s similar to other dual-cab utes.

From what we can see, that specific Triton carried an official combined fuel consumption figure of 10.9L/100km. 

In the real world, you can expect to achieve a similar number on a constant highway cruise, but be prepared for it to climb to something more like 15L/100km around town. So more like a six cylinder modern Falcon or Commodore than a Corolla or Mazda3. 

By how far did you miss the service? Was it by a 1000 kilometres or so, or did you miss it all together? If you missed the service by a few weeks or a few kilometres then I would not expect the engine to seize, but if you skipped the service completely I’m not surprised. I’m also guessing the warranty won’t be honoured because of the missed service, but depending on the circumstances surrounding the missed service you could try and negotiate with Mitsubishi for some cover.

You’re going to be hard-pressed to show that the problem was either a design or manufacturing problem, as it’s unlikely to be either. Even though the wiring loom just sits and doesn’t appear to be subjected to any stress it being subjected to all the bumps, vibrations and whatever else is happening through the vehicle in general. It could be a faulty connection; it could be any number of things. Pay up and get on with your retirement.

Any number of things could be exciting the passenger seat, the wheels and tyres, driveline, engine. It’s not likely to be the suspension/shocks, although they would be prime suspects when it comes to the hard ride. Take it to a suspension specialist and check out the options for springs, shocks and bushes.

The Brumby would have been a good choice 10 years ago, but finding one now that hasn’t been driven into the ground, beaten to death, or rusted away is nigh on impossible. Instead of buying a dodgy old your son a favour and buy him a decent car, one that doesn’t belong in a scrap yard, and will serve him well for some time into the future. I would go for a Hilux, Triton, or Bravo 2600.

You haven’t told us what model your Triton is, so we can only make general comments. Check the turbocharger, it’s not coming on as it should.

It sounds like it is going into limp mode, which means the computer is seeing something wrong, perhaps with a sensor. Being intermittent it’s hard for the dealer to fix. Persist with it and keep taking it back.

Next time it stops turn the ignition off and then attempt to restart it. It’s likely that it will start and you should be able to drive on.

The kerb weight of a 1999 Triton is 1485 kg, the gross vehicle mass is 2810 kg, the payload is 1345 kg, the towing capacity is 1500 kg with trailer brakes.
