Anyone on this forum ever owned an X5? My parents have one and whoever designed the coolant circulation system did not have longevity or stopping leaks in mind. So far since we bought it 6 years ago it has sprung a leak everywhere with regards to coolant. First it was just some random line between the reservoir and the radiator, then it was the valley pan gasket b/t the two banks of cylinders (its a V8) and another line, then it was a screw on top of the reservoir that was cheap plastic and blew, and now its the connection b/t a line for coolant overflow at the top and its leaking.

Is this a known problem with the X5 or BMWs in general? We used to have a 325is (E36) that ran like charm for 140,000 miles but this X5 is the most unreliable car we have ever owned. Any similar experiences?
