2015 tuscon se(non turbo)

[jamesmetairie]

2015 tuscon se. about 50,000 miles on it.
bought it a couple years ago from enterprise(rentals) car sales.
On long road trips the a/c will often stop blowing cool air and blow warm air.
After about 20 minutes it will be cool again.
I read elsewhere that is not an uncommon problem.
any advice will be appreciated.
Thanks

Get a gauge and check the refrigerant level.
