HANKOOK Tires Optimo H-426

ANYONE had problems with these tires exploding?

Trip from Miami-St. Petersburg, Fla July 18,2017
July 18, 2015 returning from a 350 mile trip to Miami from St. Petersburg, Fla. On I-75N, experienced a harrowing driver side rear TIRE EXPLOSION IN ALLIGATOR ALLEY about 11:30am. Hyundai Elantra has NO spare tire on a leased car. Tires are Hankook Omnipro H-426. Multiple complaints filed about these particular tires after researching. Mileage is less than 10K miles and car is only 2 yrs. old and was leased brand new.
Have “Hyundai Roadside Assistance that only tows to nearest dealership”, per CSR after call to report,requiring a trip back 30 miles. After explaining ordeal, tire explosion, rear bumper torn off, back light damage from tire being completely ripped apart and major backside damage from said incident, Davie Florida Hyundai dealership did change and replace tire that I had to purchase.
They assured us that car was safe to drive. Receipt showed multi-point inspection provided as well as wheel balance and alignment. Back on road at approx. 3:30pm, I-75N almost to same spot, (Alligator Alley) second tire explodes on driver side front making car inoperable; waited for 2nd tow(8pm) all the way home, arrived about 12 midnight. I am currently terrified of driving with other two tires on passenger side. Waiting to hear from Hyundai Customer Care about resolution, reimbursement, compensation? exchanging other tires.
