My wife is a staunch opponent of LR, despite never having owned one. Her only exposure was a brand new LR Discovery loaned to me one weekend by a dealer, in the hopes that I might buy one. I liked it except for one thing (which freaked the heck out of my wife): it would accelerate on its own. Coming to a stop at a light, pressing the brake, and the truck continued to accelerate. Brakes unresponsive as working against torque of the engine which was revving up on its own. Threw the transmission into neutral and hammered the brakes to avoid a collision. Truck revved to the top end of the tachometer, before settling down. Happened every time the truck got above a certain RPM limit. Called a flatbed to pick it up (this is a brand new Discovery). Dealer diagnosed it as a butterfly valve getting stuck in the throttle perhaps due to improper break-in. Asked me whether we'd like to try another one. My wife replied: "If it weren't for my husband we'd all have been involved in a serious car accident. I would never have thought to stick the car in neutral when coming to a stop to be able to use the brakes. We could've died. So... no." Admittedly, this was many years ago - before even BMW got their hands on LR.
Fast forward many years later and my brother bought a Range Rover Sport - which he loved. He summed up reliability as: "The truck was rock solid. Never had a single issue. Well...except for the air suspension raising and lowering itself at times. But that aside, it was great."
There's a reason Land Rover is at the bottom of virtually every reliability survey, even to this day. A friend who works for a large chain of luxury car dealerships in the UK (including Land Rover) recommended I stay away. He suggested the inside joke in the business is that people who buy Land Rovers are loyal for a reason: They don't trade in their old LR when they buy their new one, they keep the old one for one the new one is in the shop being repaired. He did also suggest that LR owners are extremely brand loyal and have a much higher tolerance for issues than virtually any other brand. I do understand that to a degree - it's a cool brand with a strong pedigree. Heck, despite the issues listed above, I've considered an LR4 a time or two. For emotional not rational reasons. But, reliability issues and now lack of a V8 (in the new models) killed it for me.
