2013 Hyundai Elantra tires problems

My daughter has a hyundai elantra 2013 with 6700 miles, she was driving at 60MPH on a freeway and her passenger front tire blew out. She lost control and ran into the concrete barrier on the freeway. She has frame and body damage to her front end. Thank god she is ok except for her collar bone area being bruised from her seat belt. She did not hit anything before the blow out. She could have been seriously hurt. No tire with only 6700miles should have a blow out like this one did. The car has nexen cp671 tires.

The tires that came with my elantra ((hankook h426 215/45 17) had to be replaced in less than 18 months as the side wall was bulging dangerously. My son who has a 2010 elantra with hankook tires had a blow-out while driving. I think these hankook tires are dangerously unreliable. Thank you.
