I was playing GT5 a lot when I had one of my motor go bad, since late 2013 I have been playing mostly AC and Race07 before that, and, touch wood, no more motor issue.
I also have to say that I am monitoring the temperature of my wheel with a Temp gauge and lowers the FFB at the wheel as soon as it reaches over 29 Celsius.
Better be safe than sorry, It all might be for nothing, as I truly wish "The VP" is right about the "new batch", but I do not think so.
In any case checking the temperature gives me peace of mind and almost adds to the immersion, as it is a little like checking water temp in a real car.
I agree GT5 generates a lot of heat from the motors, a little bit of a non sense as it is also the FFB with the less details, mostly only weight transfer.
All that said I am totally enjoying my Elite wheel and recommend to anyone in search of a great wheel to go ahead with a CSW. It is, in my book, totally worth the possible technical issues. No fatal injuries reported so far.
I might enjoy it even more when I install my mod kit from eKretz that I received last week.
