I have a 2015 (purchased in Jan 2016) F-150, 2.7L ecoboost engine with auto start stop. came to a red light and engine would not restart right away. Had to put in park then try to start. Truck restarted and I turned off the auto start/stop feature to keep truck running. Light turned green and I went when I thought it safe enough to turn through the intersection...it started to sputter and lost power while turning, I almost got hit from the side, but the other driver blasted the horn and I coasted across the intersection. Came to a stop, put the truck in park and restarted the engine.

Drove straight to Five Star Ford who had just did routine oil change and throttle body cleaning. I have always had it serviced at dealership. There was not a single light on or any warning lights on the truck and dealer found no tags when checking PCM. The lead mechanic already left for the day and they advised me I could bring it back in the morning...It did it again leaving the dealership and finally the check engine light came on and I brought it back and said keep it here for in the morning to get it worked on. With the check engine light on the code was saying fuel pump and fuel rail system.

They called me the next day to say the fuel pump was covered under warranty 5/60,000 but the fuel rail system was not covered. Not a fan of a vehicle with less than 48,000 miles having a fuel pump and fuel rail system problem. DANGEROUS at best. Worst of all the fuel rail system is costing $488 to fix, which the service manager says is 2yr/ unlimited miles...shouldn't the one on the truck work at least 60,000 miles or 100,000 miles and be covered with the power train and engine?

This has left a mark on Ford and product...they might sell a lot of trucks, but if they have problems...people won't want them. Need a more dependable truck that isn't going to get me killed in an auto accident due to faulty fuel pump that should be a RECALL IMHO.

Will go into more detail once this problem is accepted. I lost 1/2 hr of inputting information when the system would not accept my comments

Update from Aug 19, 2017: Was in 4:30 PM rush hour westbound on I88 traffic just west of Farnsworth toll plaza on 8/11/2017 when my dash lit up and my speed dropped dramatically. The gas pedal was unresponsive. I had to get to the shoulder with vehicles roaring by. I did it and restarted the engine to get rid of the problem. I was surprised it happened when I was not towing my travel trailer. I had the same problem occur 3 times in a 10 mile trip the week before when towing my travel trailer. The message Service Advance Trac would come on, no hill assist, and a wrench with loss of throttle. I had to restart the engine to continue. But now I had the problem without towing. And why would Service Advance Trac be related to a throttle body problem?

A year earlier I had the Service Advance Trac light come on when I was towing and the only effect was a loss of cruise control. The original dealer was only able to partially trace the problem. He was pointing to the travel trailer as the problem. Because they are currently on strike, I had to go to Willowbrook Ford who fixed the problem 5-6 hrs after my bringing it in for my appointment. Kudos to them.

I hope the new throttle body assembly fixes the fuel problem as well as the Service Advance Trac. replace throttle body assembly bl3z 9e926 b

While you can disable Advance Trac , it automagically goes back on >40mph. But how does a stability function relate to a fuel function? Bizzare
