qubo electrical issues

[qubo dave]

Hi all, just has my 14 year old Qubo for about 3 weeks, this one is emmaculate , its obviously done very little even with 74000 on the clock, it drives great but there are one or two electrical issues,whenever I do anything with the back seats , its a bugger to start , its like it trips out without even turning over, after disconnecting the battery a few times it will start and run ok, and sometimes it comes up with "Start,stop not available" do,nt know what I,m looking for, is it a quick fix??? thank in advance.
