Mitsubishi ASX 2020 Q&As

Check out real-world situations relating to the Mitsubishi ASX here, particularly what our experts have to say about them.

• Oil problems with my 2016 Mitsubishi ASX

  This is a very common problem for owners of modern turbo-diesel cars who only do short, stop-start runs in city or suburban traffic. When the engine and exhaust can’t get hot enough for a DPF burn-off, the computer dumps extra fuel into the engine to get everything hot. If some of this excess fuel gets into the engine’s sump, it can force the level of the sump to rise, leading to the warning light you’ve just seen.

  In the worst-case scenario, this fuel in the sump will dilute the lubricating oil and that can lead to a damaged engine. But as you’ve found, even if that isn’t the case, there’s still a price to pay to manually force the DPF to burn off as well as change the oil for fresh, undiluted stuff.

  The solution is to make sure you drive the car for at least half an hour at freeway speeds once or twice a month. That will get things hot enough for a complete DPF burn and will keep you out of the workshop. Mind you, making this sort of effort might cost you more than the fuel savings you gain from owning a diesel car. This is just one reason a modern turbo-diesel is not ideal for every consumer.

• Why is the ASX Exceed not as punchy as the ASX GSR if the engines are the same size?

  Mechanically, there’s virtually nothing to separate these two versions of what is essentially the same car. Both have the same power and torque and the transmission is the same CVT. The only real difference that could make the GSR feel a bit frisker than your Exceed is that the former is about 40kg lighter.

  Perhaps it’s your perception that is the difference here. The Exceed is the more expensive variant so perhaps it has a little more sound deadening on board. That would help explain the extra mass but could also be making the vehicle sound a little more muted and, therefore, less perky. Don’t rule out the spectre of manufacturing tolerances, either. It’s far less common (and marked) these days, but it remains that some cars are just a bit more powerful than the car that came down the same production line either side of them.

  Ultimately, even higher tyre pressures can have an effect on acceleration, but if you can detect these small differences, you are indeed a very sensitive driver.

• Is it normal for the back of my 2022 Mitsubishi ASX to sway and bounce on bumpy roads?

  It all depends on what you call bouncing and how you define bumpy country roads. But one thing’s for sure, if the car really is leaping about more than it should, it has nothing to do with the fact that the engine is in the front. Don’t accept that sort of nonsense from anybody; a modern car should be balanced to drive and that’s that.

  There has to be a degree of movement over bumps – that’s why cars have suspension in the first place - otherwise, they’d be very uncomfortable to ride in. But excess movement means there’s either a problem with the suspension itself (bushes, ball-joints or maybe even the springs themselves) or the shock absorbers aren’t doing their job by controlling and arresting the normal movement over bumps.

  Again, though, it’s important to set parameters for what’s normal and what’s not. The parlous state of this nation’s country roads at the moment means it’s possible to encounter some truly momentous bumps and potholes, many of which are enough to damage a car’s suspension, not just test its limits. Meantime, start with a check of the shock absorbers and work from there. If they’re worn out or tired, they can certainly allow more movement than there should be.

• Having trouble selecting reverse in a 2023 Mitsubishi ASX

  Intermittent problems like this one can be very annoying as they rarely emerge when a mechanic is looking at them. However, you need to have the Mitsubishi dealership mechanic with you for a test drive as you try to make the problem occur, however long that takes. Perhaps you could video the car's behaviour next time it happens and show the workshop that way.

  Common causes for a manual car to refuse to select a gear are usually down to a worn, maladjusted or damaged clutch or a poorly adjusted gear linkage. If there's a horrible graunching noise when this happens, I'd suspect the clutch, if not, it could easily be a simple matter of adjusting the selectors. Either way, this shouldn't amount to rocket science in 2024.

  Just be sure not to take no for an answer; if the car has a problem, it's under warranty and it's Mitsubishi's problem, not yours.
