 I bought the Tiburon new. I started having trouble with the tires right away. Had to air them up within first month, and every 6-8 weeks after that. Took it back to the dealer four times. They said no apparent leak, maybe a problem with the seal. So added nitrogen. 8 weeks later, a tire low again. Deal will not replace tire. Hyundai customer service says Hyundai is not responsible for defective tires, the tire manufacturer is. I purchased road hazard and extended warranty. Neither will cover defective tires. I don't feel safe driving the car.
