So do you really want to buy a toyota ?

That would hurt.
And they also had another towards their Denso fuel pumps.

I think a lot of other companys will be worried as well. We might all end up with the magic button.

This poorly "engineered?" fix was always going to be an issue.
The moron that came up with it originally was obviously on contract and is long gone.
Other manufacturers SHOULD be worried, very worried.
A vehicle must be made to suit the purpose for which it was sold.
If you cant drive a car, like a car, under normal conditions.
It is not suitable for the purpose for which is was sold.
I foresee a lot more of these class actions and hopefully a functional solution.
Like an easily interchangeable/ replaceable filter sold for a reasonable price that can be swapped out when full.
Just like an oil filter or air filter.

Some trucks sold in europe already have filters that are removeable and can be cleaned and reused.

Exactly, there is no reason ( other than lazyness) that the same thing cant be done for any passenger vehicle.
Id willingly retrofit ( or have retrofitted) such a system, if it was available.

My understanding of the article is Toyota knew the DPF's were defective and cause unreasonable wear to the vehicles and additional cost to the owners.
All DPF's will eventually clog up and fail. This will occur more rapidly if the vehicle only does short runs.

Why? Noting the new Dmax, it does active burns every 200 - 300kms use, of which only take about 3kms of travel to complete, and doesn't seem to matter the speed.

Do a search on DPF clogging. Almost every site will state short suburban driving is the principal cause of a blocked DPF

As any who frequent this forum know, im very anal about this poorly engineered patch.
But recently i have been doing less long distance driving and more medium distance with some stop start driving thrown in.
One of my primary concerns was that even though most of my driving was at highway speed for hours at a time, my regen frequencies have been all over tge place.
But i think i have it figured now.
Long distance driving at 110 ( by the speedo) means the poor old engine is barely ticking over. Between 1400 and 1600 rpm.
But the last couple of months i have been doing somewhat shorter runs with tge engine revving comfortably up to 3500 from take off and through the gears.
The irregular regens have settled into a 500k regen cycle.
The revs must be blowing out some of the stuff that regens at 1400 rpm just isnt doing.
It still gets short regens on long runs, but methinks thats because of the low rev clogging things up.
It could, of course, be helped along with that stupid EGR system pumping exhaust gas into the engine when not under load.
But that should be cured once im out of warranty and i fix it.
Ill be doing a bit more "comfortable" revving more frequently from now on to clean it out a bit.
Still dont like the thing
Still think its a poorly engineered patch
But will have to live with it.

So are auto vehicles more prone to DPD/F issues? Most are driven in 'D' which means it will change up to the higher gears at earliest opportunity.

Possibly, What rev range does a manual have at 110 kph?
I'm a little concerned that when I start towing my van long distances I plan to drive at around 100kph.
This means that the revs will rarely get above 1200 rpm (idle range)
There is a possible offset though, the gears will change more frequently on hills, the exhaust will be hotter because of the extra effort required and it will probably hold lower gears longer on hills.

100Ks (speedo) is about 1600ish, so about [edit]1770 at 110.
