I was notified by the Mazda dealership that an integral hydraulic engine mount was cracking and needed replacement. I was just past my car's warranty so I drove on it since they said it was safe. On November 8th 2013 during a service I was told the integral mount was about to break and needed immediate replacement. They said if the mount had broken while driving it could cause an accident, not to mention destroy the motor. I had them replace it but had to pay out of pocket since it was past warranty and not a recall. I researched online and found numerous complaints from other owners of the same series car and within adjacent years of the same motor mount cracking and needing replacement under 50,000 miles. Some complained about having to replace the replacement later after putting some more mileage on it. This is an obviously inherently defective part that should be recalled. Please look into this and force Mazda to recall this defect as it is a danger to public safety if one were to break while driving. Thank you so much for your time and service.
