Thanks so much for the awesome feedback guys - Gives me a lot more confidence and thanks for the recommendation on Rick's in Nerang @scarry been looking for a good LR specialist on the GC.
Very excited to get the car now, been a dream of mine for years. Gonna take it to Rick asap to do a "make sure all is OK service" whilst still under Stat warranty.
Keep the comments/recommendations coming!
Agree it's extremely difficult to work out and only JLR know the real figures. The rest is just guess work. People can speculate, but no more. I read South Africa admitted to 1.3% crank/bearing engine failure, but who knows if that's accurate (in response to a law suit) and government of Korea seems to be taking their own action. For all we know it's 5%.
Aren't the 3L and 2.7L crank failures are the same/related? 3L being a modification of the 2.7?
I tried to do a reliability poll on a FB group - numbers minuscule so meaningless but this was result:
Petrol - 4.4 V8 (seemed to be overall reliability winner too but petrol and diesel too different to lump together)
Diesel 2.7 - D4 2012
Diesel TDV6 3.0 - no result
Diesel SDV6 3.0 - no result
Even at low percentage I still can't get my head around the lottery that each time I turn the key it might be a 30k event. Would I swim in the ocean if there was 2% chance of being attacked by a shark? I would have to think very carefully.
Dying in a car in au- 5.4/100,000 = 0.0054
Being attacked by a shark in au - 1/16000 = 0.00625
Would really like a diesel but struggling with this aspect.
I don’t own one but been looking into them for a while. Prevention tips I know of:
- change transmission oil and filter every 80-100k
- change timing belts (both) 7 years or 180 on the 3.0 I think (160 on 2.7)
- engine cover can cut through (coolant?) pipes. Cut the cover so it doesn’t rub
- change the upper coolant housing T as they tend to split - someones makes an aluminum one.. but pretty exy
- plastic intake manifolds can split but not sure what best preventative is for this
- service every 10k (half what LR say)
Easy. Drive it home via the bottle shop and pick up a carton. Park car in driveway, pull up deckchair and consume carton while admiring car. They look great and can't break if they're not running.Quote:

Do take the time to sink a few coldies while admiring it though. They are lovely to look at.
The more you drive and admire, the more you will appreciate it whilst it depreciates in value anyway. So enjoy and if it fails - you can still look and admire how good it looks. [emoji3]
In all seriousness, if really worried (but you want to keep), then don’t sit on high revs for extended periods of time, try to avoid going over 3000 rpm if you don’t have to, and any vibration investigate why. One theory is vibration from the transmission adds to the harmonic stress on the crank but because the cars NHV levels are so good it is hard to notice a problem.
It is a design fault that seems to affect maybe 1% of engines and if these odds are too unfavourable then get a Petrol instead or good extended warranty insurance.
The number of failures in South Africa does sound higher than what has been experienced here in Australia - but one observation made is in South Africa you are more likely to spend a lot of time sitting on 130-160kph once you get out of the cities. High revs, high temps/thin oil, combined with insufficient undercut radius on the crank can’t be a good combination if it is a fatigue related failure or a bearing issue.
This is not to say it is the only reason it fails.

Mine went two weeks ago on a MY15 with 86k on the clock, longest service interval before I had it was 20k, I purchased in Feb 2020 at 80k and have since serviced again, plus oil changes in TC & gearbox. Crank snapped whilst idling at lights.
Sorry to hear about that - what a nightmare.Quote:

If you own one of these you have to accept this... in the end comes down to your attitude... if you're able to be relaxed and casual about it then could work for you... if you can't, like me, it's going to be difficult.

High milage, service history looking sketchy (no log books produced as yet), trans oil never changed, ride height suspension not currently working. What do you reckon?Quote:
