after tlaking to peoplea t work, i think i need a second opinion. i am going to have them fix the engine mount and then take it somewhere else.
First, your car is in warranty. Second, the mount is a warrantable repair regardless. Third, your clutch can be warranted, too!!! Do a search herein and you will come up with a growing number of individuals who had their clutches replaced beyond the 12/12 period that the dealers and Mazda try to adhere to. I had mine done recently at 45K miles!!! That is good news for you because now there is a precedence that makes it hard for them to deny you this repair withing the 4/50 period!
P.S. Chain of command at your dealership on this will be: Service Manager, General Manager, Mazda Rep, Mazda CR. Work them over and use this site for reference. Good luck!!!
