Is it a Lemon??

I'm in procedure of buying a 2007 x5 3.0 and dealer sent me copy of service book and it looks like this:

Claim Number #745000 8/15/2007 6166 miles Reversing Camera Malfunction
Claim Number #745010 8/15/2007 6166 miles Transfer Box unable to move
Claim Number #745018 8/15/2007 6166 miles Core Credits-Automatic VIA IWS-Mt Olive PDC Valid for Repair Dates from 12/18/1997
Claim Number #756500 8/25/2007 6407 miles Transfer Box unable to move
Claim Number #797430 5/14/2008 13590 miles Microfilter Replacement, 1st Eng. Oil Service-Full Maintenance, Standard Operation MP



Should I be worried about that transfer box and other problems and has anyone had same problems? Please hurry, I'm very close to buying. Thanks
