Consumer Description

SEVERAL OF THE EXHAUST MANIFOLD BOLTS HAVE SNAPPED/SHEARED CAUSING EXHAUST LEAKS BETWEEN THE EXHAUST MANIFOLD AND EXHAUST PORT ON THE CYLINDER HEAD. I'M LEARNING THAT THIS IS A COMMON ISSUE THAT HAS GONE UNADDRESSED BY THE MANUFACTURER, BUT IS CLEARLY AN EMISSIONS AND FUNCTIONALITY ISSUE. PLEASE HELP IN HOLDING THE MANUFACTURER ACCOUNTABLE FOR THIS APPARENT MECHANICAL DEFECT. AS OF NOW, THEY OFFER NO ASSISTANCE IN REPAIRING THE ISSUE.
