Hi, I am also a U.K. member of a facebook group called Mitsubishi 4n14 problems. The balance shaft drive coupling failure is an extreemly common problem with this engine world wide. It is probable that ALL unmodified engines (Diesel 2.268cc MIVEC 130KW) of this type are effected to some extent but not all owners realise. Some who have contacted Mitsubishi dealers report that Mitsubishi claim they are not aware of any such fault. However it appears that the original replacement parts that were available do NOT cure the problem and the fault reoccurs and so now the original parts are now longer available. A new design of parts is now being supplied at great expense. The most obvious symptom is a loud ticking noise from the sump area at idle. This general dies down when the engine accelerates. The ticking is sever wear of the drive coupling of the balance shaft module and mating components. If no action is taken the gear driving the shaft may also suffer tooth failure which will cause sever immediate engine failure. I consider this is potentialy a dangerous fault. Many people have removed the sump to gain acces and then removed the drive shaft coupling to the balance module. The balance module is left in place but no longer rotates. If not already damaged the drive gear and shaft can be left in place. It is reported there are no sever engine vibrations as a result of removing the balance shaft. I have not yet removed my coupling and consider this is a Mitsubishi engine design fault and should be a recall due to the risk of dangerous engine failure. I would be interested to hear about others with this engine fault

Hi I have just joined today and have a 2013 plate having done 94000 miles with a full service history. I thought my timing belt was on its way out but the engine specialist garage I have put the car in says that our local Mitsubishi dealer tells him it will be the balance shaft that has gone and is a common fault .they can supply a modified repair kit at an exstorsionists cost of £2500 plus vat. Having looked on the internet it appears that cars all over the world have been suffering this problem with the 4n14 engine and I agree its a dangerous fault which appears to me should be a recall due to it being a design fault otherwise why supply a modified kit .Cars of all ages up to and including 18 plates are affected. I am thinking about contacting the BBC Watch Dog program to see if they can help highlight the problem and put some pressure on Mitsubishi to get this sorted, so if any other owners want to do the same lets see if we can get this problem rectified at Mitsubishi,s exspense.

Thanks for your information bobbet. Yes I to would like have this problem highlighted to all owners with 4n14 engines and I think a safety recall is required. About 2 years ago I received a safety recall for the windscreen wiper motor/ linkage fault and Mitsubishi were required ro replace free of charge because it was a safety issue. I belive it was a requirement in UK for this wiper recalled to be corrected prior to issuing that years MOT. It is possible to check for outsatanding safety recalls by logging on to

l had not finished replying when page crashed so my previous post continues below.
Safety recall can be checked at I www.gov.uk/check-vehicle-recall.. There is not one for this serious 4n14 engine fault and I wonder if there is a method of informing DVSA of safety issues that the Mitsubishi are not notifying them of. It is probable we do need somone like Watchdog to assist.

I've just joined today as the balance shaft has gone on my 2015 2.2 outlander. 90k miles on the clock. Quoted £3,300 for replacement kit and repair and Mitsubishi won't contribute anything as out of warranty and not dealer maintained grrrr. Is there any case to go to watch dog on this and if so what do I need to do. Tia.

I have a 2013 plate outlander with the balance shaft issue. Bought it second hand and the problem started within two weeks. Mitsubishi Australia will also not assist with anything. For such a known problem worldwide, it’s very disappointing that Mitsubishi aren’t even at least contributing to this inferior costly part and repair. Can’t even drive my car because now I have to save a crapload of money to fix it.

Did you buy from a dealer? How many Kms? Does it have Full service history?

Sadly, I bought privately. It has 143K on it and all services were done at a Mitsubishi dealer apart from the last 3. Been back and forth emailing MMA but they just keep making other excuses to get out of it. Just have to bite the bullet and get it fixed. Any idea on what it costs?

if it had Full dealer history it would have been more likely.

I have heard of people removing the drive coupler, this is the item that wears causing the noise.This means the balance shaft will not turn anymore and engine might feel rougher. i have never seen this done though.

Cost wise? I have heard around $4000 to replace.. but cannot confirm this is correct. it is about 8 hours labour to do.

parts needed are

Balance shaft assembly and 4 bolts
Drive coupler
crankshaft drive gear
drive adapter and bolts
timing cover
thrust washer
2x oil seal rings
threebond sealer for sump and timing cover
engine oil
sump washer
Rocker cover gasket
4 injector seals
4 return seals
8 injector bolt washers

Thank you so much for your expertise with this. F-me!! 4 grand!!. Better save up some more. Lol. Cheers again for the info. I work at another dealership and they will look after me so hopefully won’t be quite that much. Wishing now I had spent the extra and bought from a dealer because it would still be under the stat warranty. Oh well. Ya live and learn.

Hi, I have also just signed up for the same reason! I bought my 63 Outlander (61k) from a dealer and have maintained it's dealer only service record. The issue with the balance shaft was picked up during a free health check. I am a little disappointed that the car I bought for it's rugged reliability could leave my facing a bill worth several thousand pounds. What is worse is that this appears to be a reoccurring fault that could have impacted on my family and my personal safety.

The chap at the local dealership was a good enough guy with his advice and took a photocopy of my service record and was is contacting Mitsubishi on my behalf to see if they are willing to contribute towards the repairs. Depending on how Mitsubishi respond will determine whether I buy Mitsubishi again...

How has everyone gone about dealing with this situation? Has anyone else had help from Mitsubishi? Does anyone have any advice for me... Please!!!

Rich

Mitsubishi Australia did not assist me at all. Even with a full service history. Pretty disgusting that this has never been a recalled part because if it fully went while doing 110kph on the highway, it could be very dangerous. Anyway. Mine is sorted now but it set me back $3300. And I was lucky enough to get the parts at cost price through work. I’d imagine retail repair cost being upward of $4000. I actually have a little video of what causes the problem. Will see if I can upload it. Good luck everyone. Mitsubishi...... you should be very ashamed of this. Most people don’t have this sort of money just laying around to fix something that is obviously an inferior part and a danger to those who trusted in your brand.

Thanks for the reply although I was really hoping for some positive news! Definitely makes me consider selling this car back to mitsubishi and buying something else... at least the problem will then be their issue to deal with. Will wait and see what Mitsubishi say first.

Hopefully because your vehicle has lower mileage, they will assist in some way. None of us should have had to pay for this though. Keep hounding them. Don’t give up if they say no the first time. Best of luck.

Hi . I started this discussion thread approx 4 months ago. Shortly after my first post I removed the sump to check the rattling noise was the worn coupling. As it was the cause I removed it. To do this you need to remove the Sump , oil pick up and the four bolts from the balance shaft module. This allows the coupling th be removed. It has a slot on one face and a tongue on the opposite face . Both showed wear and hence the rattle. Also wear on the mating surfaces. Althogh the rattle is very annoying, in itself it is unlikely to cause engine failure. However the forces causing the wear also act on the drive gear teeth and there are many cases of tooth failure. If a broken tooth meshes with the rotating tooth of the mating gear it may force the shafts apart and break the shaft housing. Thats going to be even more expensive and could be dangerous. When I removed my coupling. I went a step further and removed the two bolts holding the input drive shaft so I could remove my gear and inspect. Fortunately in my case the engine has ony done around 55,000 miles and the gear teeth were ok so I replace the gear. I am aware from others. that there are. many cases where teeth are damaged. If the teeth are ok and the coupling is remove the teeth have no significant load as shaft is idling. If the teeth are broken you have a bigger problem. If you remove the gearshaft completly there is a risk of reducing the engine oil pressure as the feed will not be restricted by the shaft. You need to find a way of blanking the oil feed. If my gear had been broken. I had considered turning away all the remaining teeth and re fitting the shaft. In any case you should refit the balance module without the worn coupling cube. If you do not replace the balance weight module, the oil feed to the module is left open and will reduce engine oil pressure. When refitting the sump take care to examine the engine flange at the clutch end. The flange has a cut out for bolts and you must run the sealant bead so the bead misses these cut outs. It will be obvious what I mean if you look. I am aware others having leaks due to not observing this point. On my engine there is only a small increase in vibration and not a problem. The engine has run well for the last 4 months and there is no longer a risk of the teeth breaking on the balance shaft gear. I am aware of many others who have removed the balance coupling without any problems. I can only advise what I did, you have to make your own decision on best repair method. The work involved is not difficult but just requires care. Good luck. Try looking on facebook for, Mitsubishi 4n14 problems Good Luck

I've just been told by Mitsubishi that my car (Outlander 2.2 diesel 2014) has this issue.. £3300 to fix but then said £2200 as I've taken it there since new etc. I'm not sure about getting it fixed as it's always sounded agricultural and the service department didn't think it would be a major problem just that it would become more noisy as it wears but this forum makes it sound more dangerous..so not sure what to believe.

I'm guessing you have to get it fixed at a main dealer if you need the new parts that fix it permanently rather than a Mitsubishi specialist?

I like the car and have had it from new but does anyone have an opinion if this could be the start of more problems if it's not reliable?

Hi,
I had the same problem on my car and at around 50,000 miles I removed the sump to check. The drive coupling was worn as expected. My engine had been making a loud ticking noise that was very loud at tick over speed and reduced as the engine speeded up. If the noise was the only Issue I would have left it. However as I have researched this problem elswhere on Youtube and Facebook 4N14problems, it was obvious the problem was much more serious than just a loud ticking noise. The same forces that cause the wear on the coupling also act on the teeth of the drive gear and its always the same teeth. There are many examples of the teeth breaking. It is iresponsible of Mitsubishi not to accept this is part of the same problem. and tell you its not serious. I suggest you collect further evidence of broken gears and tell them about it. So your problem is then to have a very expensive repair due to their design fault. In my case I decided on an alternative solution at my own risk that Mitsubishi are unlikely to accept or carry out for you.
As many other have done I decided to remove the coupling. This part is a cube with a tonge on one face and a slot on the opposite face. To do this you need to remove the oil pick up (2 bolts), remove the balance shaft module (4 bolts). As the module is removed the coupling is released for removal. I also removed the bearing housing for the drive shaft at the input end(2 bolts) This allows the shaft and gear to be removed for inspection. In my case, as milage is relatively low, the teeth were unbroken and so I replace the gear and balance shaft module but WITHOUT the coupling. As the gear no longer drives the module and therefore has extreemly low tooth forces I expect the geat to last without damage. Changing the coupling alone is not a good solution, the mating parts are also worn. This is why the repair is so expensive. Mitsubishi are supposed to have redesigned the parts for later engines. Mine is 2012 In the UK. I understand the same problem is present on much later models so I am not sure Mitsubishi have cured the fault. My engine is now running well with no loud ticking noise and only a very slight increase in engine vibration and no risk of the gear breaking. I suggest you do as much research as possible and present your findings to Mitsubishi. From what I found many engines with balance shafts in different makes of cars also have similar problems. Please post what happens to your car.
