Hello Ken and welcome to the forum. You can have your Mazda5 checked at any Mazda dealer you like (including the selling dealer), and that check and/or repair will be free of any charges IF...
1) there is no owner-caused damage causing the problem
2) there has been no modification to any part of the vehicle that could be causing the problem
3) No unauthorized repairs have been attempted that have caused the problem.
If those conditions do not apply, you get a free diagnosis and if needed, a free repair.
Go for it.
