Defective Radiators in 2015’s

Just curious to how many people have had a defective radiator. Contemplating on purchasing aftermarket radiator because my local dealer says the defective Radiators are not uncommon on the new RZRs.

Just in case anyone else if having the same issue, this is what was happening to me.
I purchased a new 2015 HLE and it overheated since the day I got it under no load and nothing clogging the radiator either. Dealer is replacing the radiator under warranty due to all the cold spots they found in the radiator, but radiator is on backorder and the dealer told me that they have seen several of their brand new RZRs with the same issue.
