LS 400 Mk4
Washer bottle float 'sunk' so light on in dash - can live with it, but there are easy fixes
Temperature illumination - both not illuminating - 1, then the other a while back, again can live with it
Rust forming on top edge on roof above front windscreen - both sides - window out and treat and respray should cure for a while
Brake discs warp quickly (genuine and blueprint) - replaced 1 set, now needs another - around 20,000 miles a set.
