Potential for Class Action -faulty Coolant system 2017-18 LRD Full Size

[Blueboy]

I'm curious to know, too. I take a different approach. My policy is to drive nothing but Land Rovers that are beyond the warranty period. My D1 and LR3 each have > 180,000 miles on them and are running beautifully. As has already been observed, proper care and maintenance are essential to longevity (as is having Tillery on speed dial). Which is not to say that bad shit can't happen or that there are no design flaws.* But if you treat your Rover right and drive it attentively, you can enjoy many years of reliable ownership.

* I feel bad for folks driving the 5.0 who either have to deal with or live in fear of the timing chain guides and coolant crossover pipes. And I have respect for the people who keep P38s going - that whole model was a design flaw, but in an oddly lovable way.

Great to hear your D1 is still running strong and you’re enjoying the LR3. My D1 just turned 118k miles and driven daily albeit just around the local area. The ‘94 Rangie just turned 132k miles which includes many miles while we had it in Europe. Both were purchased WAY out of warranty!
Totally agree if one cares and maintains a Rover properly you’ll have a reliable Rover. Of course the same can be said for any vehicle. And why I wouldn’t hesitate to get in any of my vehicles the newest being 2004 and drive to Cali.

The OP needs to backup his statement.

I really don't think you will get very far with this and LRNA. There are numerous failures with the coolant system on the D5 with the SCV6 that can be found on various forums but most seem to happen out of warranty. Also look at the later LR4s that share the same engine as they have encountered the issue as well. Now I am saying this as I am waiting for final word on my 17D5 and its engine failure at 80k. Insurnace company called Friday and said it is not worth the money for a new engine. Early D5 values have tanked in the past few months and that does not help. I have seen D5s going for less than some LR4s here lately.
Not my first LR that is for sure. I bought the D5 right after selling my D2 and then having my LR4 hit hard along the side and not knowing if it was repairable (it was thank god). I knew what I was getting into with the SCV6 (also owning a 5.0 LR4), since this was the latter part of covid time frame getting a new one was hard to find. Mine was purchased with 40k on the clock and the first thing I did when I got it home was change out all the coolant parts (radiator, cross over pipes, thermostat, hoses,, etc) just as a precaution. Zero issues since then for me until a bad tank of gas tore it up.
If you have not check landroverforums.com as they seem to have the most information on the D5 and its issues. I guess the best part of this is now I can finally get that 130 V8 I have been eyeballing for some time.

especially given my 15-year loyalty to the brand.

Let me bring it up again, since it was never addressed.

Anyone who's owned a Classic, D1, D2, or P38A, knows to watch the temperature gauge at all times and check the floor for coolant drops.
I caught our LR4 almost losing it by smell only - took it to the shop to have the crossover pipes replaced around 105kmi.
My daughter's D5 was in the shop for a classic passenger side oil leak from under the valve cover and onto the alternator (something that made me replace the alternator in my LR4 one chilly winter morning at a parking lot in Utah) - and the shop discovered the crossover pipes almost crumbling at barely over 60k miles. My WAG is the hot supercharger covering the pipes does not make things better - so the 55-60k mi should be a "service maintenance" interval to replace them.
Not cheap, but far cheaper than looking for a new engine.

From what I’ve dug up, the crossover pipe leaks (and instances of catastrophic failure) are more prevalent with 2018 and older models with the old two piece design of the crossover pipes. These were the same style pipes used on RR/RRS/LR4 as well. A one piece plastic pipe was introduced for 2019+ on the SCV6 and seems to have far less issues, seemingly zero cases of complete failure. At the least they are seeing higher mileage before they do begin to (slowly) leak. LR has now released an OEM one piece aluminum in addition to several aftermarket options too.

My daughter's D5 is late 2019.
That reminds me of a story that in 2011 or 2012 or 2013 Land Rover redesigned the timing chain guides on 5.0.
But all of them fail, including later 5.0 and SCV6.
In the U.S., we were largely spared the clusterfuck of 2.7/3.0 TDV6 breaking crankshafts. There were also multiple stories of "oh that's why it was happening" and Land Rover supposedly changing the technology, but all years were affected.

But seriously, if you've been loyal to the brand for this long then you are aware of cooling system problems on just about every Land Rover model produced since...[checks notes]...1948

On the contrary. At some point those clowns decided to make half the cooling system out of crappy plastic that crumbles after some unreasonably short amount of time. Apart from water pumps every 25 or so years, my 60yo Series trucks have zero cooling problems. Same cannot be said of my LR3, or evidently anything more modern.

I hate to hear that about a late 19’ (being I have a 20’). Did the pipes crumble under the supercharger at the inlet/outlet to the engine?

Kory, unfortunately nearly every OEM has gone to the crappy plastic bits in the cooling system. Even the vaunted Toyota V8’s have well documented leaks with plastic bits in the cooling system, some even at similar mileage to the aforementioned on Rovers

I assume so.

In general, I am trying to remember an instance when Land Rover replaced a shitty component with something better and the problem went away.
Did it ever happen?

I know, but doesn’t mean I have to like it! I feel like the manufacturers are double dipping. First they save some money using crappy plastic, then they charge folks out of warranty to repair the inevitable damage.
