Engine Exhaust System problems of the 2016 Ford Mustang

Shelby gt350 5. 2l exhaust infiltration into passenger compartment. Moderate to high rpm operation causes exhaust smell to enter into passenger area. Worse with air conditioner off than on.

Lost power in insanely busy irving/dallas intersection near major highway - could have been a huge accident! 5400 plus miles. Ford 2016 Mustang, v6 from a standing position, second car in line at red light. Light changes, traffic starts to move, I stepped on gas and nothing! had to creep across two lanes of busy traffic and limp up onto a sidewalk as that there was no breakdown shoulder. Than god the curb was about 2 to 3 inches high. Wrench icon on dash: "see manual". Turned engine off and back on - rpms surged to the red and then dropped to below 1000. Tried the off/on thing about 3 times - same results. Engine was chugging, missing, even exhaust was chugging like some old jalopy! checked the electronic gauge readings - everything was normal except the vacuum pressure - it was between 5 and 0! after several calls to dealership, Ford roadside assist and tow company; turned car off again - 30 seconds to a minute later, restarted it - and it was running perfect - engine light however was on. Vacuum level was running between 17 and 20. Towed to dealership; it's a week now and I have just learned from them that it's the throttle body. Was told that "Ford had a bad batch of these" on this engine size (v6). The part is on back order. The dealership service rep stated it's taken as long as a "couple of months" but Ford is getting faster at getting the part out, so it could be a week to two weeks to get it in. I have seen reports of this same issue on carcomplaints. Com for explorers - from Jun 5th 2016 - stating that Ford had 7000 throttle bodies on back order! this is an exceptionally dangerous situation with these things losing power like this on highways and in major traffic. Ford needs to issue a recall on this throttle body!.
