I received this PM from Dave at Billcar looking for information

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.

i would be putting a list together and doing the watchdog thing again.... nissans response of its not an integral part of the vehicle is astonishing.. if that is nissans response then does that mean you can remove the chassis and drive the vehicle without it !!!! .... i saw the picture of the one that broke in half and its frightening as to what could happen..... publicity is the only way to get anything done these days

As in my other thread...

I have suffered from a rusty chassis on the fuel tank strap area causing my fuel tank to drop.

I have contacted Nissan about this, Is it worth me contacting BillCar too so they're aware of the issue?
Check the rest of your chassis carefully. That is what happened to my truck and was the first indication that the chassis was rusted and cracked.

As far as we are aware, it is the early D40s (55-57 plate) that are directly affected.

However, they all suffer from the lack of rust protection on the chassis, so it wouldn't be a bad idea to get yours done.

the way i see it, and i'm unaware of any chages to the manufacturing process is that it's purely 55-57 plate ones affected due to age. i would imaging they all would be affected at 8-10 years old?

you have plenty time to slow it down or erradicate the potential issue though.

So today i was going to service the truck... but i noticed a crack in my chassis.. To say the least, I'm obsoletely bummed out and the truck did not get serviced.. I came straight on here to you guys to do some reading..

So the crack is on the passenger side rear between the tub and the body near one of the mounts... After reading a lot of other peoples issues, I'm hoping mine is not too bad and is repairable without too much ball ache.. So any recommendations and or comments are welcome. Also if anybody is local to Oxfordshire/Buckinghamshire and fancies helping me take the tub off and plating her up, call out and name your price. Tools and welders are not an issue here. Biggest issue for me is that my MOT is next month and the thought of doing this job on my own is very daunting when its your own pride and joy!

Hopefully Pics will follow!

Hi, it really depends how bad the rust is.
also where you are.
I have done welding on another members Truck not too long ago,
started off with a small patch and ended with nearly the complete passengers side gone.

Looking at the second pic it looks like there is also some rust in the centre of the tub mount.
this was also the same spot as the one I done ended with most of it rotted.

I will have a look again to see what the rust is like on that mount... but i guess you won't fully know till the tub comes off and start poking about..

At the end of the day, if it needs a little bit of patching or a lot, it still needs doing.

Im not far from Oxford.
Would love to help you out but
I am laid up at the moment with a bad back.
Paul.

I had an inspection by Nissan ans was told that the rust on mine wasnt something they could repair under warrenty.

Now, the next step.
Where do I go from here?
Do I see a solicitor? inform news papers? etc?

Having the fuel tank almost fall off and Nissan deny any fault seems ridiculous to me.
They also told me that there was no one else that had complained about chassis rust on the d40?! which seems to be what everyone is told!

So much for a 12yr corrosion warrenty

Why not all get together, spread the cost and get some legal help in bringing an action against Nissan UK?
There are far too many otherwise viable vehicles being scrapped because of a rust problem, and for Nissan to pretend the chassis is not covered seems to have been misleading customers. These Nissan guys need to be finding other jobs. It seems to me that there is a generic fault with either the process, the materials, or both, that needs to brought to book, not to mention that Nissan seems to be lying about having no reports of problems - can the plaintiffs produce copies of letters and emails to Nissan on the subject? If so, you need lawyers, I'm afraid...

Deja vu?
Us poor D22 owners suffered Nissan's ignorant silence around 10 years ago, when our engines started exploding!
They denied all knowledge and responsibility then, despite all the evidence produced.
Funny thing was they did upgrade their engine components, coincidence?
'My ****'!
I wish all affected D40 owners the best of luck, sorting yet another Nissan generic defect out.
This sort of inbuilt, latent defect, just should NOT be happening these days!

a mate of mine work for a car testing company and see's navara every week, all come in with rust , some so severe that his finger went through the chasis near the passenger side. i bought my navara last week and it has plenty of surface rust from working in a quarry pit and near the sea, but my mate checked it and made me sand and wire brush it down then to spray it with plenty of this stuff http://www.autopaintsbrighton.co.uk/ham ... -911-p.asp. its a messy product but is brilliant also gives me back the night black look 4x 500ml cans at 7euro each

Great idea about all chipping in.
Though it would take someone to take it all on and do what needs to be done.

A cheaper way would be for everyone to contact newspapers/watchdog/rip off britain etc all at once with their stories, bombard their fb page with the complaints etc

I have been giving this generic defect affecting D40's a great deal of thought lately (even though I own a D22).
There have been D21's, D21 facelifts and D22's where there have been NO reports of mass rotting chassis', the D40 is the fourth generation of what is basically the same chassis, even sharing the YD25DDTi engine in another guise, yet this model suffers very frequent examples of terminal chassis rusting, sadly this problem can only be expected to get worse as time passes, with more and more D40's being affected.
To my mind, something has gone very badly wrong with the manufacture of the D40 chassis, as this is the only model affected, yet it is also the newest!
Surely this fact is proof that the manufacturing process has been detrimentally changed, thereby building in a latent generic defect!
This manufacturing change is clearly the responsibility of the manufacturer, and has absolutely NOTHING to do with the subsequent ownership or usage of the vehicles?

to be honest when you own a truck with a full rolling chassis and cant afford to store it in the garage, leaving it outside in the constant rainy UK weather, water will stay trapped all over the place and rot everything. the real problem would be if the truck was properly held in a garage and then show sings of rust. parking it outside, a chassis with so many holes for water to get trapped, no offence but you are just asking for it.
