I have some revealing, first-hand news which may affect all ND owners as the mileage accrues.

I have had TeeVee (OW15 TVV) for just over 3 months now. Purchased from BMW dealer, Sytners Coventry, it was in overall excellent condition with a fresh MOT and had covered 28,000 miles.

It was driven all the way home with hood down and the car sounded good and drove very well.

However, a few days later when I had my licence reinstated, I drove out with the hood up due to weather conditions and noted that the rear suspension had a slight, intermittent knock on rough road surfaces, which I hadn't heard on the way home from Coventry.

A cursory inspection revealed nothing untoward, so as it was only slight I lived with it for a bit, but it it was getting slightly worse. When it's four-yearly service was due two weeks ago at 31,000 miles I asked Vospers Mazda (Exeter) for a full inspection - and what they found was a real shock!

The bushes in the cast aluminium uprights (or hub carriers) were found to be worn and had excessive clearance causing the knocking I could hear. I asked if the bushes could be changed, but was told that they are not available separately and THE WHOLE CASTING HAD TO BE CHANGED BOTH SIDES AT A COST OF £1,372.60 !!!!! That's nearly £500 per side + 4 hours labour!!!!!

Remember this is a low mileage, 4 year-old car with full Mazda service history.

Once I had recovered from the shock, I went into full Kev5 attack on Mazda UK (again!) I told Vospers that this type of suspension failure is outrageous on such a low mileage vehicle and is totally unacceptable. I also told them that if Mazda UK will not contribute a substantial goodwill payment towards the cost of repair I will be talking to BBC Watchdog.

Vospers were very helpful at this point, after all it wasn't their fault, so they phoned Mazda UK there and then. Most surprisingly Mazda's response was uncommonly positive and without further ado they offered to contribute 80% of the total cost, despite the car being a whole year out of warranty.

This was far more than I expected from Mazda, who are normally recalcitrant, especially outside of the warranty period. I can only deduce from this that they are aware of a weakness in the rear suspension design and durability - maybe their obsession with lightness has gone a little too far with some of the ND componentry.

More worryingly Vospers did admit that my car is the second ND they have done recently, so I fear there will be more going down this onerous and expensive route as age and mileage accrue.

I do not wish to cause unnecessary alarm to ND owners here on 'life' but I feel I have a duty to bring this potential rear suspension design/durability failure to the attention of all you good ND folk.

I must also add that after the repairs, Vospers gave TeeVee a full 4-wheel alignment on their Hunter equipment and it now drives like new.

So it should!

Thanks for the 'Heads up' Kev. :thumbsup:

I'll be listening for any knocking from my behind o_Oo_O .....Everything seems okay at the moment, but mine has only just tipped over 17,000 miles.

Had a quick 'Google', but could only find issues relating to rear coil springs, (without plastic protectors fitted) and a brake caliper 'clunk'......

Cheers......

Yes mate, I too thought it was the coil spring top coils making contact, for which a worldwide TSB was issued. Since mid 2016 resin coil spring protectors have been fitted as standard, so Mazda obviously accepted that as a potential fault.

Mazda need to take a harder look at the various problems that have blighted the lightweight ND since it's launch. It is a fabulous driver's machine, no question, but I do not believe that the current Mk4 model will make such old bones as previous models.

Reminds me of Lotus in the '50s and '60s - fantastic driving machines, but would fall apart prematurely if given so much as a menacing stare! "Simplify, then add lightness" was their mantra, as some of us will remember.

Thanks for the worrying information there, Kev. ST is 3 &1/2 years young now with under 25,000 on the clock. I think an early trip up to my specialist is now on the cards.

LOTUS, wasn't it said, Lots Of Trouble, Usually Serious?

You were lucky Kev. My mum's 15 plate Renault Twingo is at the stealers today, having a new starter motor fitted, 2 months out of warranty and 17k miles and Renault UK have shown us two fingers. That's a £600 repair.....

Sorry to hear that, Brad - no vehicle should need a new starter at 17,000 miles. Does it have that bloody silly 'stop-start' system?

As you say there was an element of luck for me, but I have to admit I did get a bit medieval when I was told the cost of my repair!

As soon as I mentioned BBC Watchdog and inherent design/durability faults resulting in goods which are not fit for purpose, things started to move.

That’s the first reported occurrence of that problem that I have seen, this thread may generate some extra traffic to Life in the short term...

Just wanted to share my experience of the issues highlighted here by Kevin...

Owner of a 66 plate mk4 mx5, done 44k since new, warranty expired in September.

During the final service whilst in-warranty we'd alerted the garage to knocking from the rear, although it was restricted to fairly slow speeds, whilst cornering over a rough surface... and nothing was identified as a specific cause at the time. But things got a lot worse quite quickly (no doubt helped by the awful road conditions in Moray), and the knocking became fairly regular at low speeds. Took it to local non-Mazda garage a couple of weeks ago, and both rear hub assemblies were identified as the cause. They had taken the liberty of discussing the issue with a local Mazda service, who said to bring it in and they'd approach Mazda UK...

... and now we've just been told that Mazda will meet 90% of the cost.

So, like Kevin, we didn't need to do any negotiating. I was armed with his experience, but thankfully didn't need it in the end.

Moral of the story - don't tolerate an occasional knock... get Mazda onto it, with a focus on the hub assemblies!

Thank you, Steve, for sharing that with us and adding 'grist to the mill' insofar as this rear hub carrier debacle being clearly a design and durability issue.

As I said in our PM, you did well to get 90% of the cost covered, which only adds to my suspicion that Mazda UK are obviously aware of the problem.

I have spoken to a local chap here in North Devon who has an immaculate 16 plate ND with only 25,000 miles on the 'clock' and his car is knocking so badly on our rough roads that he has become totally disillusioned with it, especially when I told him the full cost of repairs (nearly £1,400). He is looking to sell it in the Spring.

This is quite clearly a serious design and durability fault, not found on previous models (NA / NB / NC). Serious because such premature wear seriously affects the safe handling and stability of the car. I noted an immediate improvement in driveability after I had mine fixed.

This is absolutely NOT GOOD ENOUGH, MAZDA!!!

Took my ND for service four today, (50,000 mile) and came away with a couple of 'advisories'....

First on the list was corroding inner front and rear brake discs....Pads are on 5mm front and 6mm rear, advised to' replace discs when pads need replacing'.

.....no surprise really, given the car has done only 3,500 miles since I bought it 14 months ago.

Second was......(wait for it)....'Very slight' play in the rear hubs!! (no knocking noises or anything...Yet!)...

I mentioned to the service receptionist that speaking amongst other ND owners that the 'Hubs', were becoming something of an issue!

Her response was they will probably be okay for the next six months..... :unsure:

I assured her that should repairs become the case on a car with the mileage mine has (18,773) that Mazda will be footing the bill!!.....She appeared to have had this conversation before!! :nod:

So....We'll see how it goes in the next 6/12 months, :popcorn: .... like Kev, I'll add that the ND is a fantastic piece of kit, (yes, the best Mx yet!) but it may well be 'make or break' for me given this news......

Good luck with that, Chris :thumbsup:

It is the hub-carrier bushes that wear prematurely, rather than the "hubs" themselves, but I expect that's what they mean.

Squeeze as much as you can from Mazda, Chris - they are clearly very aware of this problem which will become more common as these cars age :nod:

Hi all. Apologies for reviving an aging thread but I thought this was worth adding to the archive for future readers. I've just made an account here after someone had linked this thread from miata.net - but I've had this exact issue on my ND and the information in this thread has been so helpful, so thank you to everyone for that.

After reading Kev5 and steve822's success in getting a goodwill payment from Mazda UK I tried the same trick and they have offered to cover 70% cost which is good enough for me after nearly fainting at the bill first time around, certainly takes the sting out at least. For reference My ND was registered September 2015 and has 42k miles on the clock, so I'm well out of warranty on that.

Hopefully Mazda have actually revised the part at fault so it doesn't reoccour in another 30-40k miles lol.
