mazda 6 2.2 sport - madza 6 engine failure under warranty - MikeyBan

I've a mazda 6 2010 without an engine too. I had the car 7 weeks when The oil light flickered on and off and after 3 miles I pulled over to dip the car for oil. It was full so I rang my mechanic who collected the car. He rang me an hour later to tell me there was serious engine damage. He dropped the sump to find the oil strainer blocked with carbon sludge and steel filings. The filings are from some major bearings somewhere in the engine. So what's the cause and who's fault is it? Either the injectors are leaking fuel into the engine, which in turn is mixing with the oil and changing the properties of the oil, it normally acts as a lubricant but also cools the engine. Now here is where I post an opinion of a former mazda technician who worked on many mazdas with this blocked sump strainer problem. Apparently when you get your car serviced with mazda they are told drop the sump and check the strainer as part of the service, this alone tells me that mazda know that there is a problem with there diesels. Every time the DPF filter regenerates it releases some diesel into the engine which again changes the oil and affects its properties, which means it can't keep the metal parts of the engine cool enough, so what happens with the heat and the friction is that the softest part of the engine gives way. This is usually the crank bearings, which is the metal filings that mix with the oil and finish up in the sump oil strainer. This in turn prevents the oil pump from picking up any oil which is a double whammy for the lubrication of the engine. This can cause failure of the engine and sometimes the turbo can also be seriously damaged. I hope someone out there will take mazda to court over this as for me I don't have the cash to risk on a big court case. Apparently this is not just a maxes problem plenty of Audi and Toyota landcrusers out there with similar problems too. I hope this helps explain the problem a bit more.

i have rang mazda and they don't want to know about it, and the dealer ( not a mazda dealer) refuses to repair or refund me so if i go the legal route, i cant afford to lose. any advice.

Hi.
You need to pursue a claim against the dealer who sold you the car in the small claims court.

Pay for an expert opinion on what caused the problem and use that to support your claim .

The court costs to you are in the region of £300 ,if you lose your not liable for the other sides costs .

You can download the SCC forms online .

Sound advice from tonyg as usual - just one small point about your remark about taking Mazda to court, -you can't because Mazda are not the vendor of the vehicle,even if you had bought it from a Mazda dealer and that's why all manufacturers sell through dealers. Not just cars, just about everything you can think of is sold through a dealer or a retailer. Even if it's advertised as a manufacturer selling direct, it'll be a separate company.

If the court find in your favour and they still don't pay up then take it to the high court and get a high court order to pay and send in the sheriffs.(Been watching the program on the BBC!)

It is indeed Tony: sometimes the advice has to be blunt and not what the questioner wants to hear - but as you show by your own posts, it can always be polite and as constructive as possible (Collos, please note). It's particularly useful to have your input from a dealer's perspective.

It's disappointing that this newer diesel Mazda is having engine problems (I'd thought it was older models than this), but as said above the claim has to be against the dealer with whom the buyer has had a contract, not Mazda even if they are to blame.

The advice surely has to be - don't buy a diesel Mazda. Indeed the longer I moderate this forum the more I think that people need to think very hard before they buy any used high-mileage diesel. Tony - is that too extreme a view?

If the car is still under the manufacturer's warranty, I would have thought that there would be a claim against them for failure to meet contractual obligations.

No, it isn't. The manufacturer may chip in with a contribution to rectification, up to 100% but the claim is against the supplier. If you you bought a kettle from Currys, made KettleKing plc, and it went wrong, where would you start your complaint? Currys!

As T says, the claim is against the dealer seeing as you've only had it 7 weeks. Is the dealer a main dealer? Not that it matters as you are covered by the SOG act. But I would also phone Mazda Customer Services to establish exactly why they "don't want to know". Is the car still under warranty and does it have a FSH? Get all the facts together and be polite with them, keeping only to the facts.

An independant engineers report will be enormously useful if you need to go through Small Claims Court.

I am going through very similar issues with my mazda 2010 CX7.

same issue - metal fileings. Whole story is on Caravantalk forum in the Towcar section under the 'Oh dear' thread.

One point alreday mentioned - small claims court is only up to £3000 which wont get a new engine for your Mazda 6 - next step is county court.

I'm in a qunadry as despite my solicitor telling me that I have a VERY good case there is 'always' a chance that you could loose.

I was on BBC yesterday talking about it. If you google BBC On Your Belhalf youll get it

mazda 6 2.2 sport - mazda 6 engine failure under warranty - tricky

Hi. My CX7 Dec2009 diesel 59540 miles, full Mazda serv history has just done the same on 14 feb on my way into work....oil light suddenly comes on.....and stays on. It has been recovered to Mazda dealers and is due to have sump removed on Monday or Tuesday for inspection.Oil level was correct. Mechanic who checke checked dipstick with me on forecourt tapped the engine cover badge and said there have been issues with this engine with the oil pickup strainer clogging up.

I would be interested to hear what Mazda's reaction was to your cx7 problem as they appeared to know the fault before the sump is removed and seem to imply some cleaning up is needed once pickup is removed. My impression is that my engine is already wrecked and despite 4 years of servicing by Mazda solely the car was never recalled whether in or out of warranty despite the manufacturer and dealer being aware.

Please do respond as I am deeply disappointed as I love my cx and had planned to keep it several more years. I am prepared to support current protestations etc and I will endeavour to get up to speed over the next few days with the links to bbc etc as provided here.

If there's a battle to be fought then you have just found another ally!

Check out the caravantalk towcar forum under the odear thread.

Rinty has been offered help from mazda, but still has to find around £2000.

Problem is the injector seals leaking, causing slug blocking the pickup strainer, and starving the engine of oil.

Presumably the present disasters are the result of progress and how the injectors are fitted, lots of different makes suffering the same fate, blow by carbonising the oil and, aided and abetted by starship mileage oil change intervals (there's a backwards step) we end up with these problems.

Why are injectors fitted like this now, it can't just be to make direct injection easier, this was never a problem with iDi engines.

As I've just posted there ...

This is the same as the issue which has been affecting Toyota's diesel engine. The injectors are in the oil in the head, so any seal leakage puts exhaust gases into the oil, which gradually sludges up - blocking the oil strainer.

I know it's no comfort, but Toyota have done a recall to replace the injector seals, and any cars showing signs of sludge get a new engine. I think up to 7 years/100,000 miles.

It did take a lot of campaigning from people who had an engine failure. In the early days they were facing much the same battles as you poor folks. I hope you get a sensible resolution with the dealer and Mazda.

Hi

I have the exact same problem, no resolution yet and a CX7 with an empy engine space and a dealer insisting I cover £960 of their costs to remove the engine from my CX7 so Mazda UK to be "sure" the failure is terminal. Of course it is.....and Mazda know this the simple evidence provided; clogged filter, carbonised injector, even the dealer new the score, they had another engine on the floor with the exact same problem. This together with all the threads on the symptoms of failure are well documented now

I see this as another discraceful stance to expolte their csutomers in time of extreme distress

Mazda UK have their heads in the sand and either they hope the issue will go away (as most of the cars failing are out (or just out) the Warranty and therby negating any responsibility on there part. or offering deals at 40/60% leaving customers paying out £2K-£4K. for the misfortune of buying one of the so called "Bullet Proof Reputation".

Well not any more

Why oh why dont hey include a simple check (even if it costs a little time and money) at service intervals ?. It took my technician 15minutes to remove the top cover and remove injectors and 15 minuts to uncover the sump.

No1 Injector covered in Carbon and the oil strainer more clogged than my Nans tea strainer.

Even an apprentice mechanic could have done this.

Can any successful owners of failed Mazda 2.2 Diesals that got a satiactory resolution please add to the tread.

A piece of advise to any Mazda 2.2 Diesal engined owners... GET YOUR ENGINE CHECKED NOW AS I CAN ASSURE YOU THERE IS NO WARNING OF THE IMPENDING DOOME !!. It occures on low milers like mine and those done average distances.

not necessary to remove the sump! When changing the oil and whilst the sump is empty, simply put an endoscope in through the plug hole to inspect the inside. Cheap endoscopes can be had off eBay for as little as £30 and most electrical wholsalers sell them aimed at electricians from about £100 upwards. No rocket science required!

Just wanted to balance some of the gloom on here and despair with Mazda with some praise for their customer service and unexpected successful resolution to what seemed to be a fatal engine failure.

My 2009 Mazda6 2.2 diesel had been running great until 5 weeks ago, when it suddenly wouldn't start and then sounded like a tractor. Cue breakdown and recovery to my usual garage, who diagnosed cam chain slippage, oil pump failure and knackered valves and injectors = new engine or scrap value.

The car has full service history, Mazda up til 50,000m, indie garages thereafter, and being out of warranty and not a main dealer purchase, I wasn't expecting too much when I phoned Mazda customer services to see if they could offer any help.

Surprisingly, they suggested getting it to the nearest Mazda dealer to inspect, which I did, and called me a day later to say that there had been a cam chain recall a couple of years ago and they'd see what they could do.

Again, I wasn't holding out much hope, but after four weeks, numerous calls and the Mazda dealer being pressed by the customer services team to dismantle the engine, inspect all the damaged parts and provide a full report, I've had confirmation today that Mazda will cover most of the cost of repair to rebuild the engine, which will come back with a two year warranty.

Had a case manager at Mazda called Zoe Doyle, who has been superb at pushing the dealership to provide reports and pursue the case, and overall it has been great customer service. Based on the reports here, I wasn't expecting too much, but Mazda has come through on this one to get me back on the road and prevent a very expensive write off

How would we know though? You put a point and then said also on Radio 4. So that could mean that was your point and view and it had also been mentioned on Radio 4.

Maybe try and be clearer in what you are saying? And think it through before putting 'pen to paper' :-)

I tbelieve there is a significant cost to getting a winding-up order (based on what our solicitor told us about a company that failed to pay us when we won a case against them).

My Mazda 6 2.2 diesel is at the local Mazda dealer for after the oil light flickered on. '59 plate, 62,500 miles, FMSH. They tell me that the oil strainer is badly carbonised, but no signs of metal fragments, thank goodness. One of the fuel injector seals has failed, causing carbonisation.

The latest I have from them is that it in not going to be possible to clean the oil strainer, and it is not possible to replace it. They suggest the way forward is a replacement of the part of the engine which holds the filter. This is supposed to cost around £680, and will take six hours at £100 p/h. Plus the replacement of the injector, and some largely unnecessary diagnostic work they claim to have done.

I'm thinking that the strainer could be cleaned up if they could be bothered to do it, and that the repairs they suggest are going to be unnecessary.

Look forward to any comments. Many thanks.

Firstly, are we right to assume that your car is NOT still covered by a warranty?

I don't know the intricacies of your engine, but it sounds odd that it has a design where the oil strainer cannot be replaced, and cannot even be cleaned?!?

And "the part of the engine which holds the filter" costs £680 alone? What part is that?
When you say filter, do you mean the oil filter, or the strainer?

I'm also a little thrown by the term "carbonised". What, exactly, has blocked-up the strainer? Has excess diesel fuel reacted with the sump oil to form some sticky gunk?

To me, their message sounds peculiar. If there is any way to get a second opinion, I'd be trying to investigate that. If the strainer COULD be cleaned or cheaply replaced by some other garage, it might be worth paying to get the car towed to them.

Exact same has happened to me, 68000 miles, full Mazda service history. had the car for less than 3 months, before engine siezed. 6 months later, solicitors fees ever increasing and still no car. Through the small claims court anything less than £10000 you can not claim legal fees against the looser. No justice for the average person and the dealers know it. You have to weigh up the cost of it all and so far a £6000 car has cost me £10000! the real question is, once the oil system is contaminated with carbon, despite being flushed and the engine reconditioned, will the oil system be clear?

Im glad to have come across this post. Im in Australia with a 2009 Mazda 6 diesel with the same problem as everyone else on here. I haven't found much info on the issue here though. There's not too many Mazda 6 diesels getting around!

Mazda have quoted me AUD$22,000 to fix the problem! The cars only worth about $15,000 so im left to search for reconditioned engine/parts and so on.

Mazda can't seem to give me a service report or a straight answer as to why the oil pressure dropped suddenly. They did however provide a list of parts it needs to be fixed (all in $AUD).

  1. Partial engine without injectors $10654.16
  2. Engine gasket set $592.22
  3. Turbo Charger $3374.62
  4. Holder Nozzle 4x $5273.31
  5. Washer Nozzle 4x $19.44
  6. Engine oil filter $20
  7. Engine oil $110.00
  8. Engine coolant $100.00

If and when my car has a new/recon engine, i will also say goodbye to the DPF and have it remapped/tuned for hopefully trouble free motoring!

A real shame they have this issue, such a great car otherwise.

Let me get this right. You bought a Mazda. It suffered engine failure. Mazda didn't want to know, so ...

you went and bought ANOTHER Mazda.

Which has suffered engine failure. And Mazda don't want to know.

Of course, you're not providing ANY real details at all. How old the cars were, if they'd been bought from Mazda, if they'd been serviced properly, if they were under warranty, etc, etc.

I suspect there's a lot more than the minimal details you've provided.

If not, then you're really responsible for your own troubles. "Once bitten, twice shy", really should apply.

Here is brief story. Both cars were bought after warranty.

First Mazda 6, bought it from trade dealer with 68k miles on clock. The car was 3 years old. I didn't service at Mazda dealer but done service regularly and I always care and look after my cars.

At 90k during driving on motorway back home I started hearing knocking noise under bonnet. Pull over, been towed home. Next day I went to local mechanic they took oil cover off- lots of metal bits in oil, "smog" ( oil suction blocked) means common problem with those engine 2.0 diesel and sounded like rod bearing.I was hit with quote for new engine!!! 4-5k pounds

I was shocked!!!!!

Decided to part exchange with Toyota Celica as I needed reliable car quick. Toyota offered 1k pounds so I lost about 3 thousand pounds!

After few years with trouble free Celica I had to buy family car. I thought I will give a try with Mazda again so in october 2013 I bought Cx7 2.2 diesel 2010 with 55k on clock from trade dealer. This car has good service history although was serviced every year but sometimes past 12.5k service schedule. Had 3 services done before I bought it: 07/04/2011 -13k miles,02/04/2012-30k miles, 29/01/2013 -45k miles. Two of them with Mazda dealer.

After purchase I went to Mazda dealer in Tamworth for service and good check up. I asked them to check timing chain and they said its fine. I drove for Christmas to Poland and all was good but there was one think I wasn’t sure about… Mazda put castrol magnatec oil instead dexelia dpf. I already knew about customer problems with dpf engines. I rung Mazda garage in Poland and they advised me to come and change it. So I went and after 20 min I been told that timing chain needs to be change!! From driving 1200 miles??? I wrote letter to Mazda customer service in UK about problem I got as well as RECAL for those engines with same problems. Mazda refused to cover the cost of 700 pounds and reason for that is the services weren’t done on time! It shouldn’t matter as this is ENGINE FAULT and mazda should cover it! Decided to go ahead and After paying 700 pounds I went back to Mazda Tamworth and hit them with bill and complain that they didn’t check properly my car. Mazda gave me 120 pounds back!! Joke!!!

I continued servicing my car in Poland at local Mazda dealer. Everything was fine for 10k miles until few days ago.

I was driving back from work on motorway and started hearing noise in engine, Sounded the same like in my old Mazda 6. I couldn’t believe it! I went to Mazda Tamworth and been told that is rod bearing and needs half an engine replaced!!!!! Quote 4,5-5k pounds!!! I asked mazda manager to speak to Mazda customer service to cover it as Its engine fault and since I bout it Id did service at Mazda dealer. MAZDA refused!!! I couldn't believe!! Why I'm bothering to pay more for dealer service as I get nothing back!!!

I got some quote from independent garages in Poland to get engine rebuild (if its not damaged completely) and they said could cost up to 1,5k pounds if of course engine still could be repaired. I I decided to ship my car to Poland at cost of 350 pounds.

I understand that this thread is about cars under warranty but I think people should be aware about how bad those engines are!

The thread has expanded over time to include cars which aren't under warranty. There is also plenty of evidence about problems about Mazda diesel engines in the car-by-car reviews section of this site (click on Mazda, then scroll down to the 2008-2012 Mazda 6).

The jury seems still to be out on whether the new (2013 - ) Mazda diesels are any better: on the other hand we get very few comments about problems with petrol-engined Mazdas.

Personally I still wouldn't buy a Mazda as the last one I looked at (the CX-3) doesn't offer a space-saver spare wheel or even anywhere to put one.

I couldn't believe Mazda have done that as well - that and the CX-3 being over-priced (in my view) will seriously turn-off customers, especially in the second-hand market where I think resale values will drop sharply once the word has gotten out about the 'bottle of goo only' policy. Its bad enough being asked to shell out for £400 for a space-saver on the 3 after already spending close to £20k for a car.

I'm keeping my 3 unless and until it gets expensive to keep on the road or Mazda and others change their policies on equipment & trim options and (less so) ensure their diesels are actually reliable. Too many compromises made for my liking at present. Glad I didn't go for the 1.6D version (I have a1.6 petrol version) when I had the choice back in 2006 (it was touch and go on the costs as I was doing about 15k miles at the time) and had to endure all the problems that followed with their diesel engines - more by luck than judgement/foresight.

Hi everyone I have a 2011 mazda 6 2.2D and when I bought it from another person it already had timing chain replacement and dpf issues at 55k miles. I regret buying mazda now as Im afraid of the upcoming services costs if the engine fails. Im on 62k miles now out of warranty and as I noticed my oil quickly reached the "x" point on the oil dip stick after an oil change. As I understand the best way to protect the engine would be to remove dpf, remap, change O rings on the fuel injectors, clean/change the oil pump mesh(filter or whatever that is) and change the oil again? And then just replace the O rings every few thousand miles and you would be safe?

Are there any mechanics to confirm that as I love my mazda and dont want to sell it and put someone else in trouble? Also heard that low-ash oil would help that oil pump running.

Nobody posted here for more than 6 months. Any news from mazda?

Illegal to remove DPF, isn't it? Your proposed fixes may prevent problems, but do you feel lucky, given the known history of this Mazda diesel engine?

Obviously me and the rest of us here didnt check what problems this engine have before buying the car and its not our fault that Mazda failed. If there is a way to keep these engines running then why not?

The best advice we can give you is to flog it before you get expensive trouble.

If you like your Mazda 6 apart from the catastrophic diesel engine, try to part-exchange it for a petrol 6. These have an excellent reputation for reliability.

The best way to keep a turbo-diesel engine running reliably is to do a decent amount of miles p.a. and very few short trips - that's what they're primarly designed for (as well as load-handling), especially for larger cars that aren't specifically designed for load-carrying.

It staggers me to this day how many wallies still buy (higher-priced than petrols) diesel-engined cars when doing not just under 20,000 (25k+ really) miles p.a., but often well under 10k miles p.a. for just local driving/short journeys, 'just' because they believe its 'cheaper' to run because of the 'far higher' mpg.

Diesels take far longer than petrol-engined cars to get to their optimum running temperature, and thus don't achieve anywhere near the mpg quoted even for urban driving if all you do is pop down to the shops/take the kids to the local school every day. That and clogging up the engines which rapidly ruins them. Same goes for those idiots (I see them occasionally at my local Mazda dealership when I get my car serviced) who buy rotary-engined cars for the same usage pattern. Not so bad for older diesel engines without all the three-lettered acronymn components (or turbos).

The problem with buying a second-hand diesel is that, unless you can guarantee how the car was driven (type of trips - length/how often), which presumably means you need to known/trust the previous owner, you cannot tell whether it has been driven for lots of short journeys or not, and therefore it may be being off-loaded now because the previous owner now knows it'll soon go kaput in a big/expensive way within a relatively short space of time.
