Engine Stall problems of the 2015 Ford F-150

Engine has stalled and gone into �limp� mode at highway speeds 4 times in the past few months. Have to pull over and turn truck off and then on to resume normal function. Got error codes about hill assist not working when turning the truck back on. Took to the Ford dealership and they could not replicate the issue. After researching online found numerous other people having exact same issue and it the resolution was replacing the throttle body. Called dealership and they said that might be it but didn't want to diagnosis it as that until they could replicate. Again voiced concern to them that if the vehicle goes into limp mode in the middle of the freeway that could be extremely dangerous. They said there were no recalls for my vehicle but appears multiple other models and years have had this recall already done.

Engine lost power suddenly and stalled, I had a wrench lamp come up with the following faults: service advancetrac/ hill descent control fault. This happened on a bridge on a highway when I was driving with my family. I pressed the throttle but the engine went into "limp" mode, no response from the throttle whatsoever. Almost got hit by a semi truck from the rear. Took it to Ford, for 2 weeks they had no idea what's wrong with it. They performed a software update and said it's good to go. The same problem happened again 2 days later when I was close to work. Stopped by a local automotive shop since I didn't want to drive it back to the dealership. We read the code and it showed a "p2112 throttle actuator control system stuck closed". I got a new throttle body installed for 376$, and never had the problem again. Apparently it's a common problem with Ford f150s made in specific dates. Did some digging, Ford issued a techincal bulletin TSB 16-0139 with this known problem. This problem is very similar to recall 13n03 � throttle body extended coverage � 2009-2013 Ford & Mercury I took the old throttle body apart, there was a lot of oil buildup inside that interfered with the motor controlling the butterfly valve.

The vct solenoid has been listed as a problem on a large number of Ford engines but Ford will not recall. The issue causes the engine to drop in idle and stall. My mechanic said he has changed hundreds in Ford engines. This is a safety issue when a vehicle stalls without waning.

Engine stalls at idle in park and at stop lights. Sometimes it's bad and sometimes not as much or can go days without doing it.

On Friday 10/28 while driving down the interstate at about 55 miles/hour at approximately 6:30pm with vehicles ahead of and behind my truck, the vehicle began to give a number of check engine alerts, at which time the engine rpms dropped to very low levels and began to stall and the accelerator no longer responded. Had truck towed to the nearest dealership within the hour. I was very lucky in this situation, for had I been in a construction area or on a bridge, the situation could have been much worse. This same situation occurred on the evening of 10/2 while driving 40mph down a state road near my home and according to the dealer who attended to the issue, the brake module had failed which caused the symptoms to arise. In that instance, the accelerate failed to respond and the engine began to stall, which it did when I pulled to the side of the road. They replaced the module a few days later. In addition, the driver side door vibrates and does not latch properly. Two dealers have failed to resolve this issue to date and I believe it is a safety concern that has largely been dismissed by the service technicians and dealerships involved. Despite numerous documented attempts to resolve this issue with Ford customer service, they have ignored this concern, have failed to respond to me in a timely manner, and declined a buyback request. I am submitting lemon law documentation for the vehicle during the week of October 31. I have spent hundreds of dollars on rental vehicles during attempted repairs to the doors and the brake module since Ford claims they will not cover the cost of rental vehicles during warranty repairs. Repair documentation attached pertains to repairs for 10/2 occurrence since the dealership has not yet had an opportunity to inspect my vehicle since it was dropped off yesterday evening. I will gladly provide info once received.

The issues started around mid July 2016 with about 11-12k miles. I was turning onto a side road where doing maybe 10 mph and the engine stalled, it restarted while in motion and I continued. The hill start assist and advance trac warning lights came on. Later that week it happened repeatedly. The dealership here in town (not where I bought it) looked at it for a few days, they thought it was because of, "all the after market stuff (radio etc) I had (professionally) installed". They believed it was the power converter so they replaced the converter when it came in (the 110v converter) I got my stereo stuff reconnected and kept driving it. Then the engine would not stall, but the warning lights would flash advance trac and hill assist. After a few days, it began to stall again, almost getting me hit pulling onto a road with 50mph traffic. The truck died, and wouldn't "restart" itself. So here I am parked on a two multilane 50mph roadway trying to start my truck without getting killed. It also happened again while pulling off this same road into a side street with a big ass RV coming at me, I was able to coast into the side street and then restart the truck. I brought the truck back in and they said that it might be the throttle body. So, I got my truck back today with the throttle body replaced. I go to drive away and my head unit/ display will not illuminate properly. I thought it was dimmed, but it wasn't. So I drive in a circle to bring it back and it illuminates like it should. So I leave and I drive back down the main 50 mph road and while accelerating away from a stop light there, the advance trac and hill assist lights flash on again. I take it right back and it is now there getting looked at again.

The throttle body failed while traveling on I-94 in a single lane construction zone during a severe rainstorm. The throttle body is a part that controls the air intake on the engine and when it fails the engine loses power and cannot pull a trailer. The engine does not stall, but it does shudder enough to shake the vehicle. I turned the vehicle off and upon restart could move out of traffic. This occurred two more times till I could make it to a dealership. This is a known problem and the part is backordered due to demand. When this part fails it could put the driver and other vehicles in a life situation as I was without an area to pull off and semis on the road with poor visibility. I have been waiting at a dealership for 3 days for the part stuck in my trailer and no known timeframe for when the part will arrive. Learned this morning that the part was shipping was canada, but no delivery timeframe.

Windshield cowl panels leak rain water into top of the engine where the two cowl pieces meet in the middle. I suspect looking at other 2015 and 2016 f150 models they have or will have the issue of leaking water onto the engine. Besides possible corrosion or damage to engine, this could cause the engine to stall and maybe a safety problem.

The first time I noticed the problem was when I went to pass another vehicle. I did a hard acceleration to pass and my 2015 f150 3. 5 ecoboost engine stalled in the passing lane on a 2 lane highway. I was doing 45 mph. I immediately got back into my lane behind the vehicle I was passing. After that incident I have occasionally accelerated hard to see if the engine would stall. Sometimes it would stall and sometimes it would not. I took it back to the Ford dealer and they replaced the throttle pack but it still stalls. They are at a loss on what is causing this erratic acceleration problem. They say they have not had any service bulletins from Ford relating to this. This happened not long after I purchased the vehicle with less than 2000 miles on it. I now have 18000 miles on it and this problem has been ongoing since I bought it. The dealer and I have been waiting to see if Ford will offer a solution but so far they have done nothing.

Truck shudders as transmission torque converter clutch attempts to lock up in third and fifth gear at light throttle position when shifting upward. This vehicle has the 2. 7l engine with the auto stop/start feature. With this feature disabled the engine attempts to stall after stopping as if the feature is trying to override the off switch. After coming to a rolling stop and then trying to accelerate into traffic the engine will bog down and then a split second later feel as if it is going to full throttle without me depressing the throttle further. The engine speed surges when attempting to lightly accelerate and maintain speed with the flow of traffic. -Ford needs to give owners the option to turn off the auto stop/start permanently. I was not informed this feature could not be removed when I purchased this vehicle. The dealer attempted to shut it off and only succeeded in disabling the remote start feature. I will never buy another vehicle with the auto stop/start annoyance.
