Hi,

As you might of heard or maybe its already posted there seems to be some Navara chassis problems corroding cracking/breaking, I have been in contact with Nissan & we are in need of the below information.

Reg Numbers,
chassis Numbers
Mileages
Photo’s


Maybe you could set up post, or through a pm they could email us direct.
I do understand that not everyone wishes to post the data of vehicle online.

Kind Regards Dave
Email, engineering@billcar.co.uk
I would appreciate if the basic information is also shared here even if it is just vehicle age/mileage and some pictures.

Nice day for Waxoiling

With 4 litres of black Tetroseal I decided to fill the chassis rails. Thinned the jollop with white spirit to ensure it went through tube OK.
I bought six metres of nylon tube and fitted the ends that came with the short tube on the air under-seal gun.
I found that I could fiddle the tube right through the whole length of the chassis from the back to the front which meant I could do the whole job in one go on each side.

1. Under-seal gun and six metres of nylon tube

2. Back of chassis rail

3. Under the front of the truck where under-seal has dripped out

Will be repeating the process in a few weeks to make doubly sure.

Yes you can book it in just call local dealer.

And I do think it's a special paint and they are pressure washing all the **** out first as well. I think it's an auto paint system they are using but rest assured I will be asking and finding out when mine gets it done initial inspection booked for July 5 th with treatment asap after.

I would hope it's a bit more than 'paint'.
Not much good sealing in festering rust!
I think it is . I will be finding out exactly what it is when I get mine done. Some of the resin types of paint can actually speed up the rot by sealing in moisture I do know nissan have been researching it fully and I think we all know that the only way to stop rust is to not let it happen in the first place. Or cut it out but they are having a good go at it.
Don't get me wrong I do think they are only trying to delay the rot past the time that it should have lasted in the first place. Why would they build a product to last for ever. But I think they are trying to mend the situation and that is far better than anything others would have done. How long should a truck last any way? I do think they are being quite honerable about it all.

agree bit like bolting the stable door but at least they are chasing the damn horse, in all honesty how many of us have vehicles that have had the stipulated inspections and services in the warranty ? Nissan could really just deal with those but it would be a PR nightmare and unlike Lancia they haven't just fobbed it off and ignored the issue (showing my age now).

For sure the drive for all this is to maintain reputation and market share and reduce the potential for a serious accident due to the flaw, personally I dont think the steel is at issue or they would all do it (a la lancia) but rather the protection was probably very minimal and has been found wanting but at least they have taken/are taking steps to mitigate it.

Zakly the balance sheet is what's driving it.
And that is why they have got to do a half decent job at it ....to ensure we buy nissan again. They know that like I have said b4


They don't want to make them last forever why would they ......they need to sell us more
The spend level of a nissan customers is short . I.e. First owner buys car and services it but nissan spend on warranty . Generally 3-5 years. Then buys a new one
Second owner may use dealers and parts another 3-5 years but aspires to buy new "caching"
The third owner uses after market parts and never visits service department. So nissan don't care .

On top of that car manufacturers only have to support vehicles for 7 years after production stops. I.e. Supply parts. Also you will notice when a manufacturer brings out a new model they are basic as the production run continues and other manufacturers bring out new your older models get more toys to keep them selling and at the end they have everything. All the luxuarys. It's just a game.

Now if the product lasted for ever non of this would help them sell more......

Look at the position of nissan in the market of pick ups. Value is what they are trying to achieve. Majority sales. Not the most expensive or necessarily the best . Ford wild track expensive, vw anorak Toyota expensive Mitsubishi , fiat, issusu San Yong now nissan is good with all the toys and you can have a sunroof now . To me looks like a good package with the new rear suspension.
The nissan tows lots , has nice rear suspension , leather, toys and not the most expensive but a good over all package. Try getting a sunroof from the others and all the other toys.

So I ask again how long should it last. The 12 year warranty was to entice the third owners to buy to promote second sales and ultimately new.
My opinion only but I bet I am right.
Ok it went wrong let's look at the problem rust in a designed crumple area. Metal being stretched into a complicated shape and designed to bend in an accident. Then squeezed the manufacturer to build it to a price to maintain margin at nissan . I suspect the chassis manufacturer looked at saving a bit to maintain his margin as well possibly a cheaper steel or a missed rust preventative process or maybe it was further down the line . The steel manufacturer at the processing plant putting in a bit more scrap or not heating the scrap enough to burn out the impurities and it all added up to this mess.
Back in the late 50s Vauxhall suffered in this way . I knew the designer of the rust spots on the pa crester , velox and the f victor. They rust proofed the doors with lead based paint. Some of the lead came from old batteries and the acid wasn't burned off so the paint was a little acidic and it caused rusting. This want known at first by Vauxhall but they suffered the reputation of the cars rusting b4 they left the production line.

Look at other products apple for example taking the Mick out of date and not supported after 4 years


After thinking about all this how long should a pick up last and are they ever abused/ overloaded / not serviced?

Please don't think I am for nissan I am not I just get the drivers behind the actions. I have budgets and want success at my work and I have constraints. They are different to yours and the next bloke but we all want VALUE.

Despite being given all the all clear last October, my D40 was inspected at a local dealer last week where they found holes, photographed and sent them off.
(I'd found holes myself when looking for a jacking point, hence triggering the 2nd inspection)

So having watched that video is that it then , am I now awaiting a "commercial settlement" for certain?
Fate sealed etc. ?
(No-one has been in touch yet)

Sadly, S2E, yes it sounds like your Navara will be condemned.

as expected passed inspection no problem just awaiting re treatment now it seems in there wisdom Nissan failed to send the equipment and materials to retreat cars should be here by weekend, to be fair to the Garage they did offer to remount it and get it back to me Today but i dont need it so will let them keep it till its done

Do it yourself protection.....

Started my own rusttreatment today. ( Chassi is okay now but rust is on its way ) On top of this there will be Noxudol 300 and 700 allover. I left the truck and paid for cleaning and rustprotection inside the frame. And the outside i will do myself.

I bought this product from the rustprotectionguys. 50 Euro for the can! Some kind of expoxy thats turns brown rust black.
Chemical magic aparently...

Will post more pics as the job gets along.

D40 new chassis protection process all years

Hi all you might have gathered there is a problem with D40 chassis snapping. You will have read in the press on face book and any one who knows anything is asking questions so I am going to post my experience that way Nissan get to recover some of there name and or get slated.

I first got my D40 oabout a year ago when the snapping was just making the news. I have learned a lot more since so I have thankfully been looking for this problem and checked out loads prior to buying mine. This was when it was supposedly just a few now we know it's all that are at risk.

Mine is very good on the outside so I wax oiled it when I got it intentionally leaving the inside as was. I queried nissan and had a token inspection from my local dealer ( I am a customer with a 64 quashqui) because I noticed a shed load of flex in the chassis when I lifted the car to wax oil it on a two post ramp.
I contacted nissan as well.

Obviously all the common faults have developed and now the clutch at 77k miles don't start me off again .

Well nissan have tried to passive me regarding a list as long as your arm of faults I have had in 10 k miles "they all do that sir."

Any way
Was one of the first to book it in on the day the video was leaked but my local dealer had no booking space for A month . That's normal any way it's in on the 5th July for the all year chassis inspection with the load bed/ tub removed.

There are loads of roumours that they cannot cope with the demand and there are no new bolts available to re attach the bed after. So I have phoned my dealer last Friday evening to see if it's still ok to bring in the truck 5 days later and it is
So game on .

My dealer does not have a body shop so they will strip, inspect and reassemble to book in later with a nominated body shop which is local .

Well that is tomorrow afternoon at 2pm . Will let you know what happens
I am interested in the next process i.e. What are they going to paint it with ?

Its an 8yo Nav you are going to have issues, quite often low use vehicles have more issues than those in hard work as they tend to be maintained better . Its difficult enough to get Nissan to take any notice on new cars let alone your age ones.I got them to look at the weight carrying issue in the NP300 when I called in there one day as I was passing HQ.The chassis to be honest if they find corrosion I wouldnt want it treated as it is damn near impossible to stop ,and im sure Nissan will absolve themselves by having it done we have 4 we are waiting to come on the list 12-14 plates our dealer says they will when they catch up with up to 12 reg ones. If I was nissan I would do it the other way round and move backwards so potentially saving a higher number from corrosion in the first place.

I know what you mean regarding maintaince that is why mine is over serviced. When in my care and why I am probably moaning because it's hard keeping the old girl on the road compaiered with other cars owned.

With regard to the chassis I feel nissan are trying to do something , yes it's an after thought and yes you can't stop rust when it starts but at least they are trying damage limitation. I mean trying to save reputation. I do feel that if they were other manufacturers they could have walked away. Saying that the trucks have been left covered in mud, or abused or worse.
All vehicle manufacturers design in rust spots and component failure. To keep you buying new. It's a fine ballence between profit and failure. But you see it in every thing. It's a away of the world I am afraid.

Nissan have been ok with me overall I am never going to win. I am afraid loyalty does not count for anything any more you have to be a tart to get the best deal nowadays and buy what you decide is best value for yourself. Just look at insurance cheep deals to get you hooked and then bang expensive rental hoping you will be too lazy to change providers.

Like I say you have to go with the best deal you can get. And so far in recent times nissan have tried to keep me or pacifie me.

So the big question would I buy nissan again ? My answere possibly but they will have to give me the product I want and be doing a deal to win my business against the competition and I will be building in a factor for unrealiability and future potential problems based on my experience.

The idea of this tread was not to bash nissan but give an account of what nissan are doing to rectifie the chassis issues.

So far they have traveled a long way from the problem surfacing,
Denial
Mounting customer pressure
Investigation
Damage limitation in buy backs
Learning the problem is a biggy
Finding out it's a whole production run
Acceptance
Realising customers have a voice
Coming up with a more longer term solution
Passification of customers.


You know what I hope is coming next. Ouch that cost us so we won't do that again to that extent and what can we do to not let it happen again.

So the new product and the next generation will be better. And I do believe that is happening in that new np 300s have plates and a shed load of wax added now. But don't think for a Minuit you will win because nissan will find another way of retaining profit margin. Prices will rise and other areas will take the hit.


Now I wonder why the paint on new Nissan's is so soft??????

As I said in another thread - it's not just Nissan with paint issues, it's all manufacturers.
Everything has a price with regard to greenhouse gas emissions and weight.

Those combined = we are where we are.

To save weight - less paint.
Save weight = easier emissions testing and less fuel usage.
Greenhouse gas saving - paint manufacture = where we are now.

Not what I or anyone wants to hear, but it is what it is.

same issue they are waiting on body mount bolts apparently they are stretch bolts and are not to be reused but they have managed to tell me both lower ball joints and a track rod are worn which is weird as it passed its MOT 300 miles ago, not worth the paper, anyway have asked for a price and put some mattresses on the floor to cushion my Jaw think my local boys will be getting that tbh
 
#859 ·
Wow just WOW got my quote from Nissan christ almighty, nearside balljoint ÂŁ549, offside Balljoint ÂŁ487, Trackrod end ÂŁ378 all plus Vat! thats a grand for 2 balljoints and a track rod, thinking it was a massive labour Bill I got the parts prices off them ns Balljoint ÂŁ327, I stopped Her at that point, I can get all Three done by my local guys and tracked for less than the cost of just that part.
