oh ok Rolls,
Im not trying to score any brownie points with my post, you have an 06 with 42k miles thats the problem, get back to me when your closer to 100K and well see if you feel the same way, and yes the hoses were replaced at 138K FYI, so dont even think for one second they could 159K miles before being changed, lol that would be miraculous, When you have to get your CV Boots done and at 42K they should just be starting to crack if not already lets how that warranty works out for you...
They point being for a high end luxury vehicle two major rating firms both have bmw's dropping in Quality control in a big way, not just on the X5 but models across the board, Any car is great the first few years, mine was to, never had to get the engine replaced or tranny rebuilt, but Im just giving you a heads up if you plan on keeping it for more than say 5yrs, you will feel the burn in our wallet, hey but if you can get a new one every few years then more power to you, you wont ever have to worry about reliability, thats why BMW leases so many vehicles, because people dont want to deal with maintenance bud, but please dont try and convince anyone they are the most reliable vehicles JD POWER 2.5 stars probably knows a thing or two and as an owner I can definitely second that 2.5 rating.
But the one area I do give it 5 stars is safety, you feel safe sourrounded by 6000lbs of steel and airbags in every corner
