NHTSA Complaint #11516646 — 2016 FORD F-150

2016 Ford F-150 3.5L LH Exhaust Manifold Failure. Resulting in the potential release of exhaust fumes into the passenger cab. Recently experienced severe flutter noise and loud exhaust noise from the Left Hand Side of my engine. After diagnosing the flutter noise upon start up and acceleration was coming from the LH turbo charger "Waste Gate" the turbo was removed and prior to replacement it was found that the two aft exhaust manifold studs were also sheared off. After several attempts to remove the two studs failed, and some internet investigation (including this NHTSA website) it was decided it was best to remove and replace the complete exhaust manifold and studs. Fortunately FORD found it in their favor to increase the number of rear port studs from 2 to 3. After installation of the new exhaust manifold, gaskets, studs and turbo charger for a total cost of approximately $3,000 the truck runs exceptionally well once again.
