Look at this thread posted here
a few years ago - this was what
was available from Pontiac:

Things haven’t changed.
Your vehicle was not engineered
and designed as a tow platform.
It does not a manufacturer tow
capacity I could find - no upgrade
for towing was offered - it has no
provision for electric trailer brakes.
Do a google search - I could not find
any receiver hitch offered for sale
for your application.
When I checked U-Haul
this warning popped up:
Contrary to what has been posted - you
cannot legally modify your vehicle and
turn it into a tow vehicle without consequences.
Your auto insurance is subject to
cancellation - if you are involved
in any type of accident - you are
likely personally legally liable
for all damages.
Because I am an actual business
I carry insurance - I comply with
the law(s).
