Nothing wrong with LR5, it just looks too much like a Toyota, i.e., ****.
No, it's the 3.0L S/TDV6 that is cranky.
Well, it does - the crossover coolant pipe, which is sandwiched between the engine and the supercharger. Not only does this location mean that the rubber tends to crack/perish over time, which can lead to a catastrophic meltdown, but it also has a stupid 3-prong connection, which again, tends to crack after a while.
I just had the pipe and water pump replaced on my RRS as a preventative measure (100,000km), and that cost R12k. Small price to pay every 100,000km imho.
