Land Rovers are almost always incredibly wonderful vehicles EXCEPT for when it comes to quality control. I bought a new 2014 Range Rover that had some basic stuff wrong at delivery - things like the hood wasn't latching properly. This was mostly stuff the dealership should have found as they were prepping it for delivery.
That was bad enough, but they also decided to go with a really stupid gimmick with the shifter dial (you turn a knob to select P, R, N, D) that was purely for show. When you turn the ignition off, the knob would retract into the center console and couldn't be operated until it popped back up. Yes, you all guessed it - it sometimes wouldn't pop up when you turned the ignition on. There was a recall for it, but I ultimately decided that I didn't want to risk being somewhere on a trip without cell phone service and be unable to drive because something basic like the shift knob wasn't operational. AFAIK, there was no workaround for it - if it didn't pop up, you were stuck.
There were other relatively minor announces such as the infotainment system being sluggish and requiring a lot of nested menus to do basic things. From the reviews I've seen of the new Defender, these issues still exist. The saving grace is that they now have CarPlay, so you can avoid some of the sluggishness, but there's still no avoiding it for things like adjusting heating controls and that sort of thing.
Fortunately demand for Range Rovers was through the roof at the time. Dealers rarely had any on the lot and IIRC it took about 4 months for the one I ordered to arrive. I traded it in after 6 months and didn't lose any money.
If Land Rover ever manages to figure out how to get their quality control to Toyota's level (or at least reasonably close), the result would be truly amazing because they really do check a lot of boxes for overall design, off road capability, and so on.
