3.0d can also suffer snapped crankshafts. JLR keep saying the issue has now gone away, until it hasn't (again).

Is that the same problem that the 2.7 doesn't suffer from

Thats the very one. 

The RR & RRS forums are full of unhappy V6 owners with low mileage vehicles with crankshaft woes steer clear.

I've also read about plenty which JLR won't cover under their own extended warranty programme because its a known fault. 

. 

But people still keep buying them , absolutely crazy ! They come on the forum & are warned about them buy one & then are on tenterhooks about the crankshaft issues, you simply can't help some people..😄

You know that other cars have similarly major problems? Like BMWs 2.0l diesels timing chain failures at sub 10k mileage(the lowest I moved hadn't reached 5k) that when you get them back to the dealer they ask you to put it over there with the others? Or the escaping conrods on M3s? How about Mitsubishi's four cylinders that snap off the front of the crank? ZF gearboxes as used by Jag and BMW, not that Mercedes own was much better?


The biggest difference between those that are moaned about everywhere - like Jags - and those that aren't - mostly German - is marketing.

The Mercedes 722.6 is pretty bombproof, and what issues it can have are readily fixed on the drive (a lift obviously makes it easier).

BMWs shortcomings largely stem from making most of the engine ancillaries out of the least heat and oil resistant plastic they could find and a VAG approach to component design.

At least, being a Toyota, the Z4 should be pretty reliable

I have the 3.0d V6, admittedly in a saloon where it has less stress, but never even think about crankshaft issues.  Now I've said that, I'm sure my next thread will be "How do I superglue my crankshaft back together "


But then every V6 Omega has a head gasket failure, you know, when the garage sees oil in the coolant....

Bit tricky to misdiagnose a snapped crank though

JLR are crap at that.  Remember all that media attention at one of the British Grand Prix events, where some Range Rovers were filmed stuck in a field (due to the incompetence of the drivers, thinking max throttle on road tyres was the solution until the cars nearly buried themselves)?

JLR contacted all the owners they could identify, and offered them a freebie off road training event, to teach them how to drive.  But never made a sound to the media about it.

You clearly don't use many JLR dealers for servicing

It was* running rough, but the alternator light was on, the aircon suddenly stopped working and none of the pullies at the front were spinning.

*before it bound itself up with a really horrible graunching noise.

I will concede that even factory level diagnosis won't give a fault code for that

[Doctor Gollum]

Re the offroad courses, surely they should offer that for customers when they buy them

No Jaguar owner would know how to open the bonnet.  Thats what franchised dealers are for

I think at one point they did for the original purchaser. Not sure if that's still the case.

In the case of that Silverstone incident, they contacted all owners they could identify, irrespective of if they were the original owners.

A reasonable gesture, but as you say, the Marketing department obviously needs better interns

In order:


in the real world, the gearboxes lose all drive. The only realistic fix is a replacement gearbox, and doing that on the drive is not for the fainthearted. Assuming you could even find one, as demand was high which meant the prices were too.


I wouldn't call the timing chain an ancillary. But you are right about the plastics, which also affect Porsche.


Do you really think that BMW, who recently used The value of perfect engineering as a slogan, feel humble enough to learn from Toyota whose speciality is mass-producing boringly reliable stuff that's also affordable throughout its life. Although they did make the Supra even uglier than the Z4, which is quite an achievement

I did the off-road training at Oakham about 17 years ago a really good day out & learnt an awful lot of the capabilities of these vehicles didn't cost a great deal then around £150 if my memory serves me correctly.

Most Mercedes owners wouldn't be aware that the bonnet can be opened. The car is magically transported from the dealer's premises to an alternate universe where it is worked upon by fantastic and superior beings, which is why the huge costs are so accepted.

Gearbox servicing is preventative maintenance, and as an example, trans fluid wicking up the loom is readily fixed with a £13 part and an hour.

People don't bother with preventative maintenance though, mostly due to 'sealed for life' marketing wank, and then wonder why things fail.

Put another way, I am less worried about my gearbox failing than I am about the weather. On the moon.
