Tire Blowout problems of the 2014 Infiniti Q50

I would like to complain about the tires on my Infiniti Q50. They are dunlop p245/40 rf19 dot u28t. I have 20,500 miles on my vehicle and have blown 6 tires. All tire failures have been cause by the sidewalls of the tires blowing out. The most recent event happened 6/4/2015 and the tire was in service since 4/18/2015. All four original tires failed and now two more have failed. Is there any recourse I have against the tire manufacturer and/or car manufacturer. These are obviously defective tires and should not be sold.

On may 28, 2014 purchased a new Infiniti Q50. 1 week later noticed a bump on the front driver side tire a dunlop 245/40r19. Contacted the dealer and they said it must be a warranty issue on the tire. A week later the tire blew up in that bump and I neither the dealer nor the dunlop dealer in pr acknowledged there was an issue with the tire. I had to replace the tire at a net cost of $530 each. About 7 weeks later another tire revealed a bump this time was the rear passenger side tire. The dunlop dealer indicated the bump will allow the use the tire until a road bump matches the exact location of the bump that will cause the tire to break and empty. On 10-04-14 that event happened and another tire got damaged. This again is a dunlop tire 240/40r19 which has engraved on it a number u28t atbr0914. According to the dealer and dunlop tire representative there is no formal recall on these tires, hence I had to replace the tire with a new one, so another $530 for a new tire. I am very concerned as a 3rd tire is now displaying a very small bump and I suspect it will develop into the same scenario of the previous 2 tires. The car only has about 7000 miles driven, to there must be a problem. The vehicle was purchased at ambar Infiniti in puerto rico. More details, pictures of the tires, and VIN # available upon request.
