There might be the odd exception, but in my experience, most newer LRs have issues somewhere. If it's not the engines then it's the electrical system, if those are ok it'll be the suspension system which gives trouble.
Don't forget that these vehicles are generally regarded is rugged, so uneducated owners tend to be rather inconsiderate to them, driving over speed humps without slowing down is a classic example. These vehicles are seriously heavy, so abuse like this takes a heavy toll on suspension components.
