I'm now on my 6th Range Rover, but they have all been old classic models, all of which have been,generally, trouble-free.
One had a transfer gearbox fail in France, after years of off-road abuse, and had to be ADAC'd home, and one had to be recovered, again in France, due to faulty after-market ignition leads. Strangely, both breakdowns occurred with my current car, owned for 7 years, and the one I've liked the best. Getting into it is a bit like putting on a favourite old coat!
I'd hardly call that unreliable, over a twenty-two year period, but I do accept that newer models are not so good.
I feel that LR have lost the plot, but they still sell every car they make.
