Tire Sidewall problems of the 2006 Mazda MAZDA5

The contact owns a 2006 Mazda 5. The vehicle has dunlop signature sport, size 205/50/r17 tires (na). While having the tires routinely serviced, the inspector noticed that the wires on all four tires were sticking out of the sidewalls. The Mazda dealer replaced two tires as a free remedy and the other two were repaired at the consumer's expense. Three months later, the front passenger side tire went entirely flat. He then took the vehicle back to the dealer and was informed that the sidewall had completely split and was not able to be repaired. The tire was replaced. The manufacturer stated that they were aware of the failure, but there were no recalls available. All five tires that were replaced on the vehicle were identical. The transmission type was unknown. The failure mileage was 15,000 and current mileage was 21,000.
