Mk4 / ND Gearbox problems

Yes its the same gearbox and will have the same issues.

The fault you describe is more likely to be the synchro issue that affects the gearbox rather than the tooth fatigue failure. This was resolved with version 4 of the gearbox.

A 1.5 car is just as likely to suffer from the synchro problem as is a 2.0, however unless it is driven very hard it is quite possible that a 1.5 may not suffer gear tooth failure as this is due to fatigue and is related to tooth loads.

To help with building a picture of these failure can you advise on when the car was registered, the mileage and the VIN, particularly since yours is the first 1.5 car that has been reported on this forum.

Thanks

hi i had my 1.5 gearbox changed about 9 months ago
cheers Martin

 

Martin, what were the circumstances, mileage etc?

I have always had trouble getting the gearbox into first and
and second. mileage at replacement was 8500 miles

 

Thanks Martin, that helps with building a profile of the failures.

No problem Paul, car was registered on 08/03/2016, current mileage is 37868, and vin is JMZND6EA610111118. 

 

Mine is definitely just a difficulty in engaging 1st and an occasional crunch/stiffness into 2nd - which TSB should i quote to the dealer? As like i say they are not worried about it and say its just how the car is - i want to go back to them before the warranty expires and get them to submit it down to Mazda UK - i have this car for at least another 42 months on PCP! I’m gonna be putting 12k a year on it too.

The document you need to quote is Mazda Repair Guidance R083/16B, see link below:

This is applicable to VIN range 100001 - 120215 so covers your car.

Others have had no problems in getting Mazda UK to authorise a new gearbox so press the dealer further.

Thanks, I’m going to go back to my dealer again with this, as at the moment I am getting fobbed off big time and my car is actually stored for winter.  I’ve been getting a consistent whine from the gearbox under hard acceleration, stiffness into 1st & 2nd, as well as the occasional crunch from 2nd to 3rd. Dealer and Mazda UK are fobbing me off completely.

So would it be wise to stay clear of 2nd  hand ND’s in this Vin range unless they have paperwork to say they have been fixed? Its why  Fiat opted to use the NC gear box in new Spider as they suspected  the ND couldnt handle the mid range torque of the turbo.If Mazda are on their 4th gen gearbox in 2yrs then thats as good of an addmitance that the 1st 3 are not fit for purpose.Should be recalling all effected for perminent fix,not fobbing customers off.

 

So, the fact that I have never ragged my car in 1st and 2nd gear, hardly ever changed down from second to first whilst above walking pace, rev match whenever I can, all resulting in general reduced wear and tear means my car is now is perceived to be of less value compared to others, who’s owners thrash their cars with a resulting general increase in wear and tear but have had their gearboxes replaced. That’s great! 

P.S. Apologies in advance to owners of ND’s who have not wragged their cars but have had failures.

Some - but not all - cars have had problems. That is undeniable . But on the basis of everything I have read it is a minority - so just like Porsche Boxster and Ford Ecoboost engine problems then .But , as the owner of an early ND, I almost feel I should apologise for not having had problems.FOMO and all that …

I really could do without people doing their best to make my car depreciate faster .

 

It’ll all pass over John.

Plenty folks still keep the faith and still buy them new.

Witness how it’s recently reported my 2002 potential rot-box shed of a Mk2 (Mk2.5) is now judged the fastest appreciating future classic at 8.9% per year.

People may not forget, but we enthusiasts know how to forgive. And, a sorted car is just that…sorted.

Wife’s car is booked in next week for a rattle/vibration so will bring up my gearbox issue again with them - quoting the aforementioned TSB - if they still don’t bite is there anyone i can contact at Mazda UK who can potentially do something to sort it for me and liase with the dealer? I am certainly not going to be paying for a new gearbox out of warranty thats for sure!Ā 

Ā 

I adore my car i really do but these MK4s do have some teething issues don’t they! I’m on my 2nd now (downgraded engine due to being a daily) and BOTH have had new roofs, both have squeaky windows, paint work is thin as holy hell (already re-sprayed front end of the black one!) and now looks like I have a gearbox issue… but despite all these annoyances - i still love the car so bloody much!Ā 

Ā 

As said above we are enthusiasts of the MX5 or we wouldnt be here - yes there are some owners who don’t have the same passion as us and love for these little cars, and things like the above would make them leave the fold quickly - all iterations of the MX5 have had issues - mostly rust - yet we still love them and throw money at them - there are times though you do want to lamp Mazda as a brand as their customer service is sometimes truly atrocious!Ā 

Ā 

John, it is never going to depreciate as fast as a Fiata.

I am also confident if that the gearbox fails out of warranty Mazda will replace it. If you trade your car in in the future and the dealer says ā€œUum, you have an early car with the original gearbox, therefore we will not give you as much for itā€ then the reply is ā€œSo you sold me a substandard car in the first place!ā€

 

 

unfortunately having worked for Mazda, they are not usually reticent to paying for ANYTHING outside of warrranty even for known issues (google the Mazda 6 and CX5 Diesel engine issue) so i cant see that changing for the gearbox issue. I would advise any owners nearing the end of warranty who have these issues get themselves down to a dealer asap! 

 

Exactly the same for me John, so I agree totally!

 

  

Tim, am I right in thinking that you meant to put ā€œthey are unusually reticentā€ instead of ā€œthey are not usually reticentā€ then it would mean they won’t pay up outside warranty which is what the rest of your post suggests.

I’m wondering if a lot of the difficulty in getting warranty problems sorted is with the particular dealer rather than Mazda UK. My dealer of choice (Nunns at Cleethorpes) is not the closest to me but they have a great reputations and I have found them to be most trustworthy. In general conversation with the service department I was told that Mazda UK tend to be good with out of warranty repairs using a sliding scale of contributions. If the vehicle has a full Mazda service history and the problem occurs soon after the warranty expires this would almost always be a 100% contribution. I’m not saying this is true, just what I have been told.

When people here are reporting a known issue with a TSB released by Mazda and the dealer is not prepared to do anything about it then I would be questioning whether this dealer was worthy of my custom.

Lots of reports on this thread and others saying ā€˜my dealer doesn’t want to know’ and others saying ā€˜my car is booked in for gearbox replacement’ without any names being mentioned. If you have posted anything similar to this then maybe you could edit your post and name the dealer in question. Would be great to know which dealers were on our side rather than approaching one of the no hope ones.

 

ha ha yes sorry that is what i meant to put - can you tell I’m tired today!
