Definitive 2.2 D4d Head Gasket Stance By Toyota

[Ant-Rav]

I think the man want's his car to perform as it should, and go relatively well. Which is not a big ask, really. it's not that old. Prob a very nice car with the exception of the most important part - the engine. I have driven Toyota for many years and love them. Until recently I had the pleasure of owning a 2000 TD Avensis. Which gave me trouble free driving for many year's. Which is what we all want. We don't all have the money to buy new or nearly new motor's. And these age of cars are being bought by those of us with with a limited budget, so hurts the pocket a lot more when they go wrong. And considering Toyota's hard earned reliability reputation u don't expect them to go wrong.

& that is no doubt why Toyota extended the original warranty of 3 years or 60,000 miles to 7 years /112k miles foc.

Cars are only getting more & more complicated & therefore are likely to fail at an earlier age than previously.

I wouldn't recommend anyone to run a common rail turbo-diesel out of warranty, no matter the manufacturer.

Meaning we cannot buy diesel motors over 5 years old. Or whatever manufacturer warranty applies. What a shame. But I do see ur point. I love owning a diesel car and its economy and the diesel engine rattle believe it or not. Problem is so do a lot of people. Is car reliability being jeopardised by them being more complicated, yes it is. And that is a pity. When we buy used cars we should research its used car reliability from existing owners via the web. It is a great help. This forum being a perfect example.

On a Toyota you can extend the warranty up past 10 years as long as the mileage falls within the limits. Personally, for a private owner running an older car on a budget I think that there is a lot to be said for the 1.8 VVTi (post facelift) or the 1.8 Valvematic. Increased fuel consumption, yes, but the potential of expensive repairs much less (as long as you maintain) - no DMF, turbo, DPF etc..

I agree totally with you on using the internet & forums like this to check out common issues pre-purchase.

 

Mind you, car quality/reliability has improved overall over the years - I remember working for a blue-chip company as a rep in the 80s which changed their cars at 60,000 miles or 3 years, whichever came sooner. The Scottish cars were usually changed at 18-20 months & the Escorts that the trainees had fell apart even at that - they ended up giving them base Sierras in Scotland only ... ;)

Sadly, these days I find you really do have to do research into the specific car you're after - I don't think you can just rely on brand as much these days. For instance, modern Fords have come a long way in reliability (No doubt helped by their use of Mazda tech) while traditionally bullet-proof german manufacturers have taken a lot of hits for reliability over the years.

It's why I'd never buy a brand new car unless it'd had a long production run. Warranties are all well and good but after reading about people's experiences here, trying to overcome resistance to actually get major problems fixed under warranty, and/or having to risk thousands of pounds on e.g. having the engine taken out to be examined first, kinda puts a damper on that for me.

 

On the subject of diesel reliability, I do think diesels have become less reliable as time has gone on due to all the emissions control bodges they have bolted on; Old diesels were pretty much indestructible and the fact that you could run some of them on chip oil with no real problems is a testament to that.

The problem with diesels, especially modern ones, is they are work horses; They can't deal with just being used to pootle to the shops now and then because they need to be run hard and hot regularly to keep them in good shape. I think that is why my Yaris has had none of the problems all the diesel naysayers keep bringing up - I am using it the way it's supposed to be used!

The design flaw in the AD-series engines has been a recurring issue on this forum, but that's not a diesel problem, it was a design flaw. Even the petrol engines have had their share of problems; Snapped lift-bolts in Corolla VVTi's was a common subject in this forum when I first joined for instance, and the older 1.8's had a rep for burning a lot of oil as they aged.

You just gotta do the research; Forums and things like the Good/Bad bit of the Honest John website are invaluable and essential these days!

Not expecting for them to do anything!

No doubt all these problems with the diesels will start to happen in the petrol versions (all car makers) ranging from turbo;dmf;egr etc etc! All cheap manufacturered parts to keep costs down 🤔

[Cyker]

Sadly that is true; We've already had some people with EGR issues on petrols since they've started bolting those to petrols too, which is daft;
The EGR's sole purpose is to reduce NOx emissions - It makes everything worse including particulate emissions and reducing mpg, but that shouldn't be a problem on a petrol engine unless the fuel-air ratio mix has gone wrong and it's running lean!
With a good mix at the right ratio, and the low ignition temperature of petrol, there shouldn't be any significant amount of free oxygen to combine with nitrogen!

Good example is the Auris 1.2 Turbo which replaced the 1.6 Valvematic engine.
