Hi,

I’m considering purchasing a face lift RRS 2018 onwards and wondered if the v6 diesel crank issues ever got resolved throughout MYs?

Thanks

If you mean the small number of snapped crankshafts, then no, the crankshaft wasn't changed over the years.

It's worth remembering that, although a horrible thing to have happen, when one thinks of how many 3.0 V6 diesels that LR sold (across the Discovery, RRS and FFRR), the number of failures is thankfully pretty small and the risk likewise.

If it's a big worry but you still want a RRS, how about the V8 diesel? Lots of lovely grunt and still decent fuel economy on a run. 2012 SDV6 - it's missing a couple of cylinders
2008 TDV8 - it was a labour of love and is much missed

Thanks for the response.
Unfortunately due to the car allowance scheme I have through work, I need to keep to under 210g/km and 3.0 or under for engine size. So it’s between the sdv6 and p400e

My 2018 snapped it's crank . I have just bought extended warranty in case it happens again . Before buying the warranty I enquired as to whether it would cover a crank failure as it's a know manufacturer's defect with a bulletin issued . The warranty company said it would as all replacement engines have an upgraded crank and thus it wouldn't be a manufacturer's defect if it went again . Whether that is true or not I don't know but either way at least I won't have to pay for repair . MY24 Dynamic SE,MY21 HSE Silver, MY20 SQ7, MY 18 RRS HSE Dynamic , MY 16 RRS Autobiography now gone & MY 2005 Discovery 3 HSE that I will be buried in !

Most manufacturers have their own problems, for instance Porsche had bore score on 997 and most others will have some problem. If you don’t want one then don’t buy one…..simple really Joined the X5 45e club

Not to mention the 997 infamous IMS bearing that was modelled on a washing machine bearing - only worse (don't ask me how I know)!

the issue with the cheese cranks is that JLR wash their hands off the problem, and most people affected then end up with massive repair bills.

had JLR stepped up and just replaced the engines, then it wouldn't have been such a major issue. --

I have purchased one, a late 2017 RRS. I don’t see where you get off on minimising the issue. I’m still sat on this chair waiting to find out about other engines that the crank snaps on.

At least if you're sat on that chair you won't be driving your RRS and risking the crank snapping.  2012 SDV6 - it's missing a couple of cylinders

Isn't the issue that it's not their engine - it's a Ford / PSA engine adapted for Land Rover's use and produced in Ford's factory. I guess they could have paid Ford to redesign the crank and then take the future breakages of the old version on the chin, but the question is - how many have actually failed?
It has been suggested hereabouts by a couple of LR indies that the crank failures are usually associated with low oil levels. Not helped by the engine not giving a low oil warning, of course.

Didn't JLR take over the production of these engines in 2012? --

You may say it's a small number of snapped crankshafts. However, name me another engine which is known for snapped crankshafts, that has been a continuing fault for over 12 years? I'll pull up a chair as I know it's going to be a long wait.

A lovely example by Ford.


There is no such thing as the perfect engine by any manufacturer. Engines are literally trying to tear themselves apart with the forces exerted on them with each rotation. Joe
