We were driving south on [XXX] near Ashland, Oh. We heard a knocking that got very loud and bad quickly. There was a loud metal on metal BANG. The entire dash lit up for a few seconds, I braked quickly pulling off the interstate as safely as I could. Shut the car off and called for a tow. We had it towed to Mikes Auto in Barberton, Oh. Thats where still is. The mechanic diagnosed the issue as GRENADING. The lower end of the engine blew up. It EXPLODED!!! No warning lites whatsver before the explosion. How ds that happen? Do you realize how bad that could’ve been? $300 tow and a $6700 bill for a new engine. I will have put $15000.00 In this PC O [XXX] in less than one year. We have been Honda owners since 1992. Now I know how a F O R D owner feels like. My bought our first Mazda yesterday. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
