Picking up on Marlot's post about Toyota injector copper seals.
At one time Diesel injectors were screwed or clamped into the outside of the cyl head, just like an equivalent spark plug, there is no earthly reason i can see why that still isn't the case, any leaks of fuel or blow by become obvious long before they can destroy an engine unseen from the inside.

Toyota Safety System. This ADAS is touted as a safety benefit, but is very unreliable in some models, and verging on hazardous. It is affected by low sun, and brings up a flashing bright warning sign in the dashboard, and ceases functioning until the engine is turned off and then on again. In the rain, in cold weather and sometimes for no obvious reason, the useful automatic headlamp main beam system switches off, despite the windscreen being clean. Can be switched to manual, which required the selector to be turned through "off" whereupon all lamps extinguish. Dipped beam only when you need (and can use) main beam is not a strong selling point on unlit rural roads. Warning signs flashing up time and again are distracting.
It seems to be a problem with Auris and Avensis. Later designs, Prius 4 and CHR have a better basis (millimetric radar) apparently.
Toyota are struggling to solve this: there are a lot of examples.

All the gubbins to make a diesel cleaner and less polluting. It's an extremely old design that still operates the same as it did years ago. It highlights the fact that it is a dinosaur as far as modern life is concerned, trying to collect all the soot, stop the vibration reaching the drivers feet, clever electronics and high precision injectors to try to smooth the combustion, and although you might not feel the vibration from a diesel, it's still there under the bonnet putting a lot of stress on the electrical components and connections, which chafe and wear out quickly.
Non of it is durable as the car gets older - as we have been finding out.

Currently - my award goes to Nissan for their Navarra pick-up chassis that literally falls in half.
I didn't realise it was so widespread until I googled for it.

There's ten screens of the problem on the Yaris website: www.toyotaownersclub.com/forums/topic/171123-toyot.../

Indeed. And 17 on the German Auris site - tinyurl.com/gv44wkc

Thanks fo all your replies.
Surprised not to find the BMW 2 Litre engine mentioned with the chain cam at the rear of the engine which apparently can catch on the bell housing.
Can someone elaborate.

Chain cams aren't a problem.
The problem comes with BMWs extended service intervals, which can see the oil in there for 20k miles at a time, by which point it's utterly useless. A few years down the line, all that additional wear caused by the oil being knackered causes the chain to fail. The chain is also lubricated by fine jets of oil being sprayed onto it. So, again, degradation/contamination of the oil leads to those fine nozzles getting clogged up, and the chain snaps.
The extended service interval was brought in for the fleet market to reduce ownership costs in the first 3 years. For no other reason. Once all that engine wear becomes a problem, the fleets have long sold the car.
It's highly noticeable that makers who stayed with short service intervals, even if they have chain cams, have far fewer problems.
Of course, the problem is largely eliminated if you use cambelts, rather than chains, but you then get additional maintenance costs that way instead.
The best way of avoiding the problems is by cutting the BMW oil change interval in half. So, instead of every 18-20k miles, get it done every 10k miles, or annually, whichever comes first.

Renault Megane II headlight bulb change, needing to go through the wheel arch.
On Jaguar S type the V6 gets misfires because the three spark plugs on the bulkhead side corrode from water running off the scuttle and into the bores, and the inlet manifold has to be removed to change them.

Another cracker from the French...
MK I Citroen Picasso. To change the battery you need to unbolt the front passenger seat because some communist twit decided it would be clever to put the b***** thing under it and that it would be funny not to fit any sort of release system for the seat!

Dacia another French owned company imported right hand drive versions of the Duster from India and the rust was showing through the White paintwork within six months of purchase.
But what's going on with the Nissan Navara ? These cars have been around for a long time. Is this a new phenomenon or does it affect older rusty cars.
|
It's mainly with the D40 that came out in 2005, I believe.
Most likely a combination of factors. Lack of factory rustproofing, lack of chassis care and maintenance over the years, and heavily laden vehicles.
The oldest ones are now 12 years old, and yet people are expecting them to still pull and lug weights that they did when new.

I don't think that is a valid excuse RobJp.
A cut/paste from a Navarra owner's forum 2015 here:-
Finally got a reply from Nissan GB Customer services. Their spokeswoman told me that the chassis is not considered to be an integral part of the vehicle so they would not honour the 12 year anti corrosion warranty.
So for Navara D40 owners with rusted chassis rails , your wonderful 12 year anti corrosion warranty is not worth the paper it's printed on.
My chassis is so badly rusted , the garage are unable to weld it as there is nothing left to weld too. The corrossion from the inside out has spread over most of the rear chassis rails.

As usual in these things, the devil is in the detail, however.
To start with, Nissan commercial vehicles - and the Navara is classed as such - are covered by a 6 year perforation corrosion warranty. Not 12. That comes straight from the warranty handbook, which is online. It also specifically states that the corrosion warranty 'covers body sheet metal panels'.
The warranty also states that the vehicle must be "inspected, and repaired if necessary, by an authorised Nissan dealer. Inspection and repair is required 3 years after the warranty start date and annually thereafter."
Finally, the warranty handbook quite clearly states that they belong to ADR (alternative dispute resolution), and that "If we are not able to resolve a dispute, we will refer you to Motor codes, a Chartered Trading Standards Institute ADR provider".
So all those people bleating on about Nissan not covering them for their chassis rails failing, I'll lay a pound to a penny that the annual inspections have never been carried out AND that the vehicles are well over 6 years old, or had been grossly overloaded. Because if they had done the inspections, then they owners be quite willing to go to Motor Codes, and Nissan would be told to carry out the work.

I think you should contact this firm of solicitors RobJP.
www.attwoodsolicitors.co.uk/helping-nissan-pick-up.../
I'm sure they would value your knowledge and opinion on the subject - it might save them from undertaking a unecessary court case.

Regards the parasitic website ... erm, I mean solicitors website ... it's very notable what they do and do not say, and the very weasel words they use. It's also very noticeable that all their 'work' is on a no-win, no-fee basis, and they are 'investigating' whether people would have claims or not. Hell, if it was that obvious then they'd just be going for the throat.
I suspect that they're just trying to drum up noise - hey, it's free publicity.
They're also probably the most (in)-famous of the particular parasite ambluancus-chaserus-spivus. They have links up on their website for VW claims, the Emissions Scandal (their word, not mine, and a different one from the VW claims), Aerotoxic Syndrome claims (I'd never even heard of that one before I read their website), and lots of others.
If there was a real issue with vehicle safety, then VOSA would have done a recall. There have been 15 recalls over the years involving the Navara (both generations) however none of those include rust.
Here's one of the cases of an 'indignant' owner. 2005 Navara, owned from new. In September 2015 it failed. It had covered 22,000 miles a year in the intervening 10 years. The owner had to find his nearest Nissan dealership, as he had no idea where it was, due to the original one having closed down in the intervening decade. That tells you a lot ...
On the website where he ranted about it, others did the same .
2006 vehicle, 230k miles.
2006 vehicle, 158k miles.

We appreciate that you don't like solicitors RobJp but consider:-
If there wan't a problem with the product, merely with the users of the product, why are so many of this model year reported as failing?
Firstly, you said it was the way the product was used and not cared for by users.
Then you launched a rant against solicitors - yes, very fashionable is that.
No one likes solicitors- until they need one.
I expect that you have a solicitor on speed dial RobJp-just in case any of your stock strays on to a road and causes an accident.
But, there are literally hundreds,possibly thousands of this model failing, in of all places - Australia.
No salt, very little rain -hot climate- explain that away if you can.
I've done my time on the warranty desk for for a major manufacturer in the past, some failures are defensible, neglect, lack of maintenance, lack of dealer service history etc - I wrote the book of "100 reasons to reject manufacturer's warranty for warranty engineers" as did a lot of other warranty engineers!
But this this kind of failure is in no way defensible-period.

>>Their spokeswoman told me that the chassis is not considered to be an integral part of the vehicle
Can't see them winning that one in court. It would however need somebody to call their bluff.

Do remember to open the drivers window first as when the new battery is connected it auto locks the doors.

Renault Megane II headlight bulb change, needing to go through the wheel arch.
Even worse on the Renault Modus - the complete front bumper has to be removed in order that the headlight units can be removed to access the bulbs. I eventually got this down to a 15 minute job - I had plenty of practice!

Merc autos are so good almost sacriledge to spec manual, how did you fare selling a proper Merc (with correct wheel drive) with a gearlever.:-)
Should have put the gearbox designer in charge of the whole company, it obviously didn't happen because Merc automated manual boxes in their lorries are...words fail me.

We got the odd poverty spec 190 or C class in with a manual box which ruined an otherwise nice car with its clunky slow witted change, long travel clutch and of course daft foot operated parking brake that you couldn't gradually disengage like a normal handbrake, you pulled the lever and had to be ready to catch it on the clutch on hills.
