Tire Bulge problems of the 2013 Volkswagen Jetta

Toyo 225/45r-17xl 94v ultra z-900 all season bw, dot 73h8 2650116. 2013 Jetta tdi VIN 3vwll7aj4dm356942 two of these tires failed on my vehicle. In both cases the sidewall developed a bulge on the outer sidewall and had to be replaced. The first incident occured within 3400 miles. The next failure occurred within 22000 miles. These tires are rated for 65000 miles. In the first case les schwab replaced it at no charge. The second failure was replaced at a cost to me of $143. 93. Has there been a recall on these tires. Since 2 out of 5 tires failed in the same manner within 22,000 miles, I suspect there might be. Can you tell me if there is? thank you!.
