Very probably not. However, there has been an old rumor around the Tesla community about it, and random anecdotes given, some on these forums. Some of these rumors seem to support the aftermarket community wanting to sell sunshades. You'll have to judge for yourself the validity.
If it's beyond what you're comfortable with, but you still want solar relief, just pick one of the many shades available from Tesla or others. I think Tesla's is only like $100. The advantage of a shade is you could remove it in the winter months and enjoy the small amount of extra radiant heat.
