Mitsubishi Problems

No car is perfect, but we've gathered everything relating to the Mitsubishi reliability here to help you decide if it's a smart buy.

Should the thermatic fan run constantly in a 2005 Mitsubishi Lancer?

Answered by CarsGuide 17 Sep 2020

A thermatic fan is designed to run only when it’s needed. As the name suggests, it should switch on when the engine attains a pre-set temperature and then turn off below that temperature. It’s a way of having the engine run at a more constant temperature as well as saving the power normally used to run a fan that isn’t needed the whole time. Sometimes, a second electric fan will cut in when you turn the air-conditioning on, but the short answer is no, a thematic fan should not run all the time.

What is causing my 2009 Mitsubishi Challenger to cut out?

Answered by CarsGuide 11 Sep 2020

If the engine runs when you apply some throttle but won’t idle, I’d be drawn to the idle stepper-motor which is a small electronic actuator that is designed to keep the engine at a stable, steady idle when no throttle is applied. It’s a pretty simple fix, but I’d also check things such as fuel delivery pressure and ensure that the ignition system is in good condition, also. Don’t forget air and fuel filters, either, they’re simple things but critical to how an engine behaves. Low battery voltage can also make an engine like the Challenger’s play up at idle, too. Also, have the throttle-position sensor checked. If this fails, it can leave the computer guessing about what the accelerator pedal is trying to tell it.

What is causing my 2014 Mitsubishi Pajero to blow black smoke, jolt through gears and only go 60km/h?

Answered by CarsGuide 11 Sep 2020

The Mitsubishi Pajero is actually regarded as a very reliable vehicle, so your experience is not typical. There are several potential causes for this, but the thing I’d check first would be the air filter. Is it possible this was overlooked during the recent service? A blocked or dirty air filter will certainly make an engine blow smoke and operate poorly.

I’m assuming your vehicle is a diesel, so it would be worth checking the suction-control valve on the back of the fuel pump, too. Also, a stuck injector that is pouring fuel into the engine can also potentially create these symptoms. I’ve also heard of the Pajero diesel suffering from a build-up of black gunk inside the intake system that can also cause symptoms like the ones you’ve described.

What is causing the squealing noise when I accelerate in my 2014 Mitsubishi Mirage?

Answered by CarsGuide 11 Sep 2020

The drive belts on the engines might be new, but what about the pulleys they run in? A pulley with a worn bearing can start to squeal when under load, such as when you start to accelerate and the belt has to speed up. Also, any coolant or oil on the belt can make it screech, too. When the belts had just been replaced, they were nice and clean, but after a few kilometres have passed and contaminants have been able to build up, you might be back to square one again with a screaming rubber belt.

Check the belts for coolant or oil (or anything else) on them as well as the pulleys and tensioners to make sure a small leak in the engine is not being spread all over the place by the belt. Check the belts for correct tension, too, as this can vary over time and is a classic cause of noisy operation. It does seem odd that both cars have started to make the noise in unison, but stranger things have happened.

What is causing my Mitsubishi Triton GLX auto to shudder?

Answered by CarsGuide 11 Sep 2020

When you say the suspension has been upgraded, did that, by any chance, involve raising the ride height? Problems centring around shuddering and vibrations, vague steering and the vehicle generally having a mind of its own are very common among owners who have paid good money to have the suspension hiked by anything from two to six inches.

Aside from the legal and insurance implications of this, raising these vehicles can throw the wheel-alignment settings (particularly the caster angle) out of whack and lead to the problems you’re experiencing. There are fixes including eccentric suspension bushes to return the angles back to normal, but it’s a specialist job.

Beyond that, a vibration at a particular speed can often be traced back to wheel balancing. The wheel and tyre combination on these vehicles is quite heavy, so making sure all the balance-weights are where they should be is critical.

What is included on the 2012 Mitsubishi Lancer InStyle?

Answered by CarsGuide 11 Sep 2020

We have no record or recollection of the Mitsubishi Lancer InStyle from any year sold in Australia, and nor are there any Intense or Basic models sold in this country in which to compare and contrast it to. It appears these may be European-specification grades.

Can the 2020 Mitsubishi Outlander tow a small caravan?

Answered by CarsGuide 11 Sep 2020

As most smaller caravans (two and four berth ones) weight between 800kg and 1300kg, you shouldn't have any problem towing one with a 2020 Outlander. The petrol-powered 2.0-litre and 2.4-litre models have a towing capacity of 1600kg, the diesel-powered ones can haul 2000kg and the PHEV plug-in electric vehicle version is limited to just 1500kg - so probably not that one if it's one of the heavier small caravans you're considering towing.

Please note that the towing capacity is the maximum the car can haul, which means if you have 300kg of luggage in the boot, and have a total of four people collectively weighing 300kg, you'll need to add 600kg to the weight of your caravan. Thus, with an Outlander 2.4L petrol, the maximum caravan weight including four people and luggage should not exceed 1000kg.

What is the best family SUV for around $20000?

Answered by CarsGuide 11 Sep 2020

While the Mitsubishi Outlander is spacious, reliable and easy to drive, our experience testing it against rival medium SUVs have found it to be noisy and a little too firm riding to be truly comfortable and relaxing. At your price point, there are better alternatives out there. 

Have you considered a Mazda CX-5? In petrol or diesel, we have found it to be a superior and more economical proposition, and is definitely quieter and more refined. Plus, the Mazda's all-wheel-drive system is more sophisticated and better at dealing with loose surfaces like sand.

A late-model (post 2014) S5-series Subaru Forester 2.5i petrol is far more economical than the earlier iterations, since it switched to a more efficient CVT continuously variable transmission. And there's also the 2.0D turbo-diesel which is economical. This, too, is a fine SUV on-road or for light off-road driving.

Finally, the Nissan X-Trail diesel is a roomy and capable choice, especially from 2017, when it received a 2.0-litre turbo-diesel to replace the older 1.6L unit.

Is something wrong with the acceleration in my 2016 Mitsubishi Pajero Sport?

Answered by CarsGuide 31 Aug 2020

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.

What four-wheel-drive should I buy?

Answered by CarsGuide 25 Jul 2020

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.
