My 05 CRD KJ has been fine since I bought it in 2006. The only problems we had were a faulty sensor in the first year which seemed to think the bonnet(hood) was open at any speed over 40mph - solved easily by the dealer, and a heating fluid leak last May which took some tracking down! Turned out to be a very tiny split in a pipe, which could have happened to any make.
The only other problem was a fairly scary vibration - turned out to be caused by one of the OEM Goodyear tyres - it had a full-width defect on the inner tyre wall, so not visible until the dealer took all the wheels off to check the bearings.
