NHTSA Complaint #11533561 — 2014 DODGE DURANGO

Manifold bolts regularly break on Dodge Durango V8 vehicles. Mine are broken, which results in exhaust leak and interferes with the exhaust system, leading to engine check lights and potentially other performance or emissions issues. Symptoms include a loud ticking sound that comes from the engine bay at startup. FCA issued a service bulletin on this known problem and many customers have reported this issue on internet forums dedicated to this vehicle. Several customers have had these bolts break multiple times. The engine block and the manifold are different materials so they expand at different rates with increase in temperature. This places excess stress on small diameter bolts, which eventually fail due to this defect.
