Exhaust manifold studs are breaking on the ecoboost V6 engines (Gen 1 and Gen 2 series trucks), causing exhaust fumes to enter passenger area of vehicle when the heater/AC is on. The exhaust studs are on the back of the engine and happen on both sides. Ford knows of the problem and refuses to recall to replace them.

Upon receiving vehicle from dealership in july 2012, ecoboost hesitates, then it takes off and goes faster than you want the vehicle to.this happened many times to pass vehicles or speed up to enter highway from on ramp. After starting and letting sit for more than 10 min., putting in drive or reverse, vehicle runs at high RPM & takes off on its own.upon stopping at light/ stop sign, vehicle will lunge forward.upon trying out ecoboost on vehicle one night, the engine would not disengage from ecoboost, pressed brakes,& wouldn't stop, ended up taking down a partial fence and ending up in a ditch.truck wouldn't get out of ditch, every time you pressed on gas to try to get out,even in 4x4, ecoboost kicks in & spins wheels.truck towed and damage fixed at dealership bought from.they repaired truck per my auto insurance coverage, but when asked to check brakes,ecoboost, they couldn't find any errors per computer and engine is performing correctly. But, engine is not as we have gone back with truck many times to complain about these issues and get the same answers.a computer is only as good as what humans put into it.there is an aftermarket computer chip available at expense of truck owner that will correct the hesitation when going into ecoboost, but nothing to fix the problem of the truck disengaging immediately from ecoboost when brakes are pressed. Ford should have put computer chip in engine before selling the vehicle and making sure the ecoboost disengages immediately upon braking. Also, exhaust fumes enter the cab when you put heat, defrost, A/C on. The recirculate button has to be on all the time to keep vehicle exhaust out of the cab interior. But, the dealership cannot find an answer for this problem either. Ford dealership or ford doesn't seem to be concerned w/ these problem.read on-line that many f150 ecoboost trucks built from 2/2012 to 5/2012 have problems.
