2021 Mitsubishi Pajero Sport Pricing and Specs

By and large, a car should perform the same day in, day out without any huge (or even noticeable) changes in its performance. So I’d say, yes, something is wrong with your car. As for the cause, well, it could be anything from poor fuel to a faulty battery to a park-brake that is sticking on. It’s impossible to diagnose problems like this one remotely, so have it checked out at a workshop. Continuing to drive it with a fault is asking for more damage to be done.

This is a really common concern, Raj, especially among people like you who are considering their first diesel-powered vehicle. Modern diesels are very efficient and powerful (compared with old-school diesel engines) but those benefits come with some compromises including higher maintenance costs and potential glitches such as the DPF problems you’ve noted.

DPF problems are usually the result of the filter becoming clogged with the soot from the diesel’s exhaust. There’s not much you can do about a diesel engine producing soot (apart from making sure it’s tuned properly to minimise the soot) so the filter is designed to regenerate when it starts to get full. That process requires heat and that’s where the problems start. A vehicle that is only driven around the suburbs often won’t create enough heat in the exhaust system to allow this regeneration to take place. At that point, the filter becomes clogged and requires either manually cleaning or, in some cases, replacing. Neither is a cheap process.

So, what you need to do is to take the vehicle for a drive at highway speeds to allow things to get hot enough for DPF regeneration to take place. This drive needs to be at least about 20 minutes and it needs to happen at least once a month. So the answer to your question is not really how many kilometres you need to drive, but what sort of kilometres. Even if your four-times-a-week trip to work is, indeed, 50km, if it’s all done in stop-start, low-speed traffic, then it won’t be enough.

The bottom line is that a turbo-diesel isn’t really the right vehicle for a lot of urban-based people. The catch there, is that a lot of vehicles that were once available with a choice of petrol or diesel power are now diesel-only propositions. That includes the Pajero Sport, of course.

I’ve heard of a few Mitsubishis whose owners have experience creaks or knocks coming from the steering column, but yours is the first one I’ve heard of where the column has actually separated. The fact that it happened on the move is crazy and makes me wonder whether it was a one-off or whether this could develop into a trend. Like all modern vehicles, the Pajero Sport uses a collapsible steering column which is designed to collapse in a crash to avoid protruding any further into the cabin. Perhaps it’s this joint that has failed, but I really can’t say without looking at the vehicle.

Whether Mitsubishi will offer you your money back will probably be dependent on a few things, including whether the vehicle has been modified in any way and whether it believes those changes may have contributed to the failure.

As well as contacting the dealer – which you clearly have – the other piece of advice would be to contact Mitsubishi Australia’s Customer Service Department on 1300 131211 immediately and get the ball rolling towards a resolution.
