Px2 Rangers becoming faulty?

[BradZ]

So recently I've seen an alarming number of people bashing Px2's for being faulty and having a number of problems. At first I thought " surely not, they're selling incredibly well and Px1's are great utes "
But the more I look, the more of this I see.

I have seen a lot of injector failure complaints and the odd zf problem. But I heard just today that apparently there has been a case of one becoming a runaway. And by that i mean the thing you expect from million kilometre truck motors.

For those who don't know what a runaway diesel is, I'll do my best to explain to the best of my knowledge.

It's when they get so much blow by they get enough oily residue/fumes/mist back through the intake via the pcv ( i think) that they dont need the diesel to run and they begin to run off their own fumes per say.

As they begin to pick up rpm, more blow by is pumped into them which in turn increases rpm and so on. Once it begins, the engine will just keep climbing in rpm untill catastrophic failure. Hitting the key wont save you as the engine is already running without diesel and there's no ignition source to kill either.
I believe the only way to stop them is jamming the engine somehow or smothering the air intake, although you need to do it fast or its too late.

That's basically how it works, I'm sure someone will be able to explain futher or correct me.

So why is this happening?
My theory is now that they're so popular they're rivaling the Hilux that perhaps they are being rushed and built too quickly?
As far as I'm aware, Px1 are rock solid.

I'm worried this will become the norm and the Px2 will get the reputation of being this generations Yd25 (Navara) or Zd30 (Patrol).

I'm looking to buy a Px in the near future and as much as the 2's look fantastic, I was considering a series 1 just because of price, but now hearing these horror stories has swayed me.

So, what do you all think? What have you heard? I'd like to hear your thoughts.

Where did you see this alarming number of people bashing px2s. The pub, a toyota forum..... Everyone I know first hand talks highly of them. I'm only 12,000km in so can't really comment on longevity. No complaints in terms of build quality so far. Especially after coming from a jeep and a ba falcon before that. I know five other farmers around here with PX2s and no problems at all. Unlike me they work them hard too, towing grain bins and fuel back from town. Some have over 100,000km and no drama at all. I bought my px2 to hang on for a long time. If it turns out to be a turd it will get traded on a mustang near the end of the warranty. Then back to a nissan for the next ute probably.

Yep, seeing more and more complaints about them.


Built as cheap as possible with the lowest cost wages etc. all the car companies do it now. Quality is out the window.

[BradZ]

BPXR6T, few stories from mechanics fixing them, few from forums, Facebook groups etc.

Dont get me wrong I'm not bashing them. I'd kill to own one. Price was already scaring me away let alone hearing all this.

Im glad yours is going great, seems there's a few lemons starting to show their heads.

I'm amazed by the runaway story though, only ever seen it in very tired old truck and tractor motors. Have no evidence to sight that shows it actually happened, so who knows.

Pretty much all of the ones Rio bought, are no longer on the road. They barely lasted 2 years.

I know mine roads and access roads are pretty rough on a vehicle, but I think it's as good a gauge of a vehicles quality.

I was a huge fan of the Ranger and also the Amarok, both the best dual cab 4wds on the road according to the motoring journalists, but up here in the Pilbara they have and are failing.

I've heard of one PX1 that had a runaway diesel. I hadn't even heard of the term till today but my dad was telling me ages ago about a bloke he knows had an engine revving on it's own till it blew up. Then today I saw a video on facebook of a brand new ranger revving it's guts out, smoke pouring everywhere. By the sounds of it, it's not a common occurrence, but it can happen.

That video sounds exactly like what I was told about. I didnt know where to find it though...

Sounds like Patrol and Cruiser territory

Why do some new vehicles break down? well any make and model is known to do so!

Don't think the PX ranger is renown for injectors failure or runaway engines, sure a couple might have suffered this but for the amount sold no way!

Oh here is a link of one doing engine runaway ........https://www.youtube.com/watch?v=Yg-id-mb0JA

No they're obviously not renown for either, I'm hoping it stays that way. I just hope this isn't the start of it

Same engine and same auto (BTW they're not a zf). But the px was more reliable then the px2? Doubt it.

and people knock my Captiva !!

90% of diesel runaway is by turbo failure, around 2% is natural build up oil in the intercooler (that should be drained at 6 monthly intervals)..
rarely is it blow by.

[RHR]

And a catch can would prevent this?

[Smoke Pursuit]

I'd love to know where all these lemons are?? Most of my clients run them with no problem.

The biggest downfall is when you mod them it seems or don't maintain them.

Agree. Im coming up to three years with mine since buy new and the only issue I've had was the input shaft seal in the transfer case was leaking. Fixed under warranty no big deal. With the amount of them on the road id be pretty confident that this sort of incident is out of the norm.

How does a turbo failure cause runaway or uncontrollabe over revving.Over revving stuff ups I have heard about have been caused by accidently filling up with petrol

They are in the top sales chart every month, there are a lot around so yes we will hear of more issues compared to smaller sellers.
Plus they are the type of vehicle people heavily mod, drive hard and talk about online.

[mick74GT]

We've done 30000k in ours and haven't had any problems. It's been great.

For what it's worth

Pretty sure it would be from a turbo seal leaking allowing engine oil that lubes the bearings to enter the intake manifold.

Big truck engines blow turbo seals sometimes......Side of road remove and replace jobs.

seals fail in the turbo, oil pressure from the feed line they drink..

yes but not necessary, as the intercooler is the catch can.
simply drain the intercooler.

Those videos are pretty scary. Some other videos showed the only way to stop it in an auto is to block off the air intake before the engine destroys itself.
Do rangers come with a sort of air kill switch by chance? Or can one be installed?

install aftermarket..

yes; Maitland diesel, Berrima diesel, Detroit, cummins, cat, mack, Volvo, will have these air shut off..

What do you think happens every time you turn the key off all modern diesels have a butterfly valve in the intake manifold to strangle the air supply when switched off .To answer your question they already have one.

don't know about that,, i see them all over the Rio sites still, yes some have fallen apart and Rio had to get suspension/off road upgrades from when they arrived on sites, but they are still buying them and using them

This.

They have their issues but then so do all vehicles. My fathers PX has had a leaking rear main and is on a second gearbox. Mine has been faultless.
