I was at my Mazda dealer today getting my rear hatch struts replaced today and went back to the parts department to get some moly oil. The gentleman behind the counter noticed what I was in for and said the big hangup on getting replacement struts was because the shipping company Mazda used filed for bankruptcy a few months back and millions of dollars of parts were stuck on the docks until the case went through the courts. Toyota, Honda and others used the same company out of South Korea. Hanjin is the name I Believe.
