My 2015 f150 ecoboost has 100,000 miles on it. Over the past 10 days the truck has repeatedly lost power while driving in traffic on the highway. It happened while going up a hill on a cross-country trip, as well. The RPM drops down to 500 RPM, rough idle, no acceleration at all, hill assist light wrench light check engine light passenger air bag light and see owners manual pop up on the instrument panel (limp mode). Pulled off to side of road and had to stop and re-start the truck several times before we could continue our trip. I checked codes and logged a p2112. After some online research, I cleaned the throttle body. Looked online and youtube to discover this problem is not just me and frequently happens to others. This is a safety issue and could result in an accident. The truck should not enter limp mode for a minor issue like this. Luckily I was able to safely get over on the shoulder each time. I recently had my truck in for a recall and PCM software update. The rear differential went about a week after the update, and now the loss of power. (see https://youtu.be/hxqvxxejzqo)
2015 Ford F-150 engine complaints
Page 9 of 11: complaints 221 to 250 of 284, newest first, as owners wrote them.
Tl* the contact owns a 2015 ford f-150. While driving 75 MPH, a rattling noise was detected and the vehicle vibrated violently while decreasing in speed. The downhill descent control active warning indicator illuminated. The vehicle was taken to summerville ford (9700 dorchester rd, summerville, sc 29485, (877) 477-1434) where it was diagnosed that the throttle body needed to be replaced and reprogrammed. The vehicle was repaired. The manufacturer was made aware of the failure. The failure mileage was 100,000.
My 2015 f150 ecoboost has 79,156 miles on it. Over the past 3 days the truck has repeatedly lost power while driving in traffic on the highway. The RPM will drop down to 500 RPM, rough idle, no acceleration at all, hill assist light wrench light check engine light passenger air bag light and see owners manual pop up on the instrument panel. Took my truck into ford today and they replaced the throttle body under my extende warranty not their emissions warranty as stated in their owners manual of 8 years or 80,000 miles. Called ford and they don't know about an emissions warranty in their owners manual. Looked online and youtube to discover this problem is not just me and frequent with others. This can really cause a horrible accident. Luckily I'm a cdl driver and was able to safely get over on the shoulder this time. I'm not confident replacing the throttle body was a fix as it is a bandage to happen again at any point in time. This truck now is compromised and I wouldn't want any of my family using it or depending on it.
Tl* the contact owns a 2015 ford f-150. The contact stated that the vehicle lost power and stalled without warning. There had also been some difficulty shifting gears from drive into park and reverse because the gear would not fully shift in place. The vehicle was not included in the federal safety agency campaign numbers: 19v075000 (power train) and 18v894000 (engine). Apple ford lincoln of apple valley (7200 150th st w, apple valley, mn 55124, (952) 431-5900) was unable to diagnose or repair the vehicle after it had been taken back and forth more than once. The failure recurred with the vehicle stalling at any rate of speed and the vehicle was taken back to the dealer due to the potential risk of a crash. The vehicle was not included in the federal safety agency action number: rq17010 (power train). The manufacturer was notified of the failures. The approximate failure mileage was 3,000. *bf. Consumer replaced throttle body, both times vehicle lost all power other than idle @ roughly 60mph.
2015 f-150 3.5l ecoboost driving on highway at speeds 60-75mph went to "limp mode" losing all acceleration with warnings "service advance trac" "hill descent control fault" and "hill start assist not available" along with the service wrench light. Resulted having to pull over on interstate 10 with busy traffic, also while in the middle of a traffic light turning left. This has happened 6 times. Ford dealer has diagnosed this as a throttle body issue and will be replaced at my cost
A/c compressor and evaporator assembly failed on a 2015 truck with 50k miles! Just out of the blue the A/C compressor started making a loud noise and subsequently failed very shortly thereafter. Had to get it replaced. In connection with this problem, the evaporator assembly failed as well and was leaking freon into the cabin of the vehicle. Had to get that replaced. $2k worth of repairs - unbelievable. A simple google search shows this to be a common issue - this needs to be recalled!
Truck unexpectedly lost power while driving on state highway. Dash lit up with service advancetrac, hill descent fault, see manual, airbag fault, and the service wrench. Immediately went into limp mode. Turned engine off, restarted and continued driving.
3 series of incidents involving the same problem. In january of 2018 I identified a problem where the engine just dies under acceleration and 3 different warnings appear 1) hill climb assist error 2) service advance trac system 3) service engine, see owners manual. On jan 10, 2018 dealer could not find problem. Situation happened again in early april of 2018 and this time they identified the throttle body. It was replaced and issue seemed to be resolved. Issue resurfaced again on dec 7th 2018 almost causing a serious traffic accident. Appointment scheduled with dealership on wed dec 12 2018. All 3 occurrences almost resulted in accidents one nearly a broadside as I turned left across traffic when the engine died. I'm very concerned that this could result in serious injury or even death and ford is aware of the issue according to the dealer service person. This was reported after earlier incident and the complaint number is 11083485
My f-150 has had 2 turbos in 1 year go bad on it, causing me to not be able to accelerate at highway speeds. Losing gas mileage and coolant also. My tire sensor has also gone bad on the truck and caused me to over inflate it.
I was on the highway and the hill start assist/traction control lights started coming on. A few hundred miles later, more dash lights started flashing and then all dash lights went off and the truck lost all power. I could no longer accelerate. After a moment, it started working again. After a few more miles, it did it again, and this time when it powered down, the ABS break system went on and created a terrible grinding noise and brought me to a stop on the side of the highway. I limped it on the side of the highway, trying to find an exit, and the truck repeatedly did the lights flashing/power down/breaks applied several more times at low speed. The nearest exit was about 10 miles, so I had to continue to do this for some time. Once I was at an exit, I disconnected the battery for about 20 minutes. When I re-connected the battery and started the truck, everything seemed fine, but now the check engine light was on. I decided to just risk it and keep driving, so that I could get home. About 100 miles later it started doing the same thing again. I was close enough to home to get off the highway and take back roads home. It did it a few more times and then quit doing it. This was a very dangerous situation, as my truck basically stopped while I was on the highway going 70 MPH, and could have caused a serious accident, and left me no option but to either be broken down on the side of the highway or drive at very low speeds on the shoulder. The ford dealer that I took the truck to told me that they can't replicate the issue and all diagnostics come back clean, so they are not able to fix anything. Others online that have had the same/similar issue have said that ford said that it is a damaged throttle body that needs to be replaced, but the dealership that I went to did not suggest that as the cause.
We had a throttle body issue this summer and had to have it replaced and towed. During driving, we lost all power, major safety issue! When I asked ford about it, they said they didn't know about the issue; however they issued several recalls regarding this. This truck isn't in the recall, which makes no sense. It is evident that ford has a major issue with their throttle bodies I have spoken with ford several times, they are not helpful and are refusing to pay for this.
While driving on the freeway the vehicle shuts down and the hill descent control light came on and then the engine light. This happened 3 times, I took it to autozone to be tested and the error code - p2112 throttle actuator control system- throttle body needs to be changed. After researching, I came to find out this is happening to thousands of ford vehicles. Ford had a recall on some vehicles for this, but if your make and model was not on there they will not cover the cost. Ford knows this is a dangerous problem, but will not issue a recall. It is only a matter of time (if not happened already) that there will be a fatality due to this body throttle issue. We as consumers should not have to worry about our vehicle randomly dying on the roads, worry about killing someone else or our own families just to commute. Ford should be ashamed of themselves.
Tl* the contact owns a 2015 ford f-150. While driving 30 MPH, the vehicle stalled and failed to accelerate. The contact stated that the failure also occurred while driving 60 MPH. The vehicle was taken to jim bass ford (4032 w houston harte expy, san angelo, tx 76901, (325) 949-4621) where it was diagnosed that the failure was due to the throttle body. The vehicle was not repaired. The manufacturer was contacted. The approximate failure mileage was 70,300. *tt
Tl* the contact owns a 2015 ford f-150. The contact took the vehicle to signature ford lincoln (1960 e main st, owosso, mi 48867, (800) 364-2868) for an oil change and was informed that there was an 80% leakage from the oil pan. There were also additional oil leaks coming from the front cover. The manufacturer offered only a partial refund of $500 for the repairs, but the total repair cost was over $1,800. The manufacturer later offered a $700 refund. The vehicle was repaired. The failure mileage was 77,918.
Engine abruptly dropped to a rough idle with no throttle response while in traffic. Display console reported 'service advancetrac' and other warnings. I managed to coast to the side of the road. I shut off and restarted the engine and was able to drive normally. The same symptom repeated the next day. This is a repeat of the same symptom that occurred at about 17000 miles. At that time the dealer replaced the throttle body under warranty. This time the vehicle was out of warranty, so I replaced the throttle body myself and fixed the problem. I subsequently disassembled the old throttle body to see if I could identify the root cause of the problem. As an experienced electronic engineer, I have a better shot at doing this than many. Upon disassembly, I noticed black discoloration on the connector to the motor that controls the throttle. The material of that connector appears to be tin or a tin alloy; the black is likely an oxide that can cause an open circuit. This looks like a phenomenon called 'fretting' that can occur in connectors when vibration is present. The usual fix is to change to gold plated contacts, and/or ensure continued lubrication of the contacts. I've attached an article on 'fretting' for reference. Based on the fact that this problem was not permanently fixed by the first replacement of the throttle body, it appears that ford has not implemented a design change to manage it. It's likely that the problem will recur and require repeated fixes. This is dangerous in traffic because it's not always possible to coast to a safe location with a non-functioning engine.
While driving in traffic, the engine abruptly cut to a rough idle and throttle became unresponsive. Warnings to service advancetrac and hill start assist popped up. I coasted to a stop, which was dangerous in traffic. I turned the engine off, then restarted twice and vehicle then behaved normally. The same problem recurred the following day. This is a repeat of a problem that occurred early in the life of the truck and that was fixed by the dealer under warranty by replacing the throttle body. This time I bought and replaced the throttle body myself and have fixed the problem. Loss of engine power in traffic is a dangerous event. The fact that this is the second failure of the throttle body in my vehicle suggests that the problem is not under control by the manufacturer.
While driving my truck (typically at moderate speeds - 20 - 30mph) it will suddenly reduce rpms to about 500 and the speed will drop to around 5 MPH. Simultaneously with that occurring I will receive the following warning indicators "hill start assist not available" then another warning "hill descent control fault" then another warning "service advancetrac" then "see manual". This happens typically while accelerating and has occurred on city streets as well as while merging on a highway on ramp (bad situation). The resolution is to turn the car off an let it sit for a second then start it and drive slowly. This is widely documented across the internet with no identified cause and constitutes a severe safety hazard.
2015 ford f-150 ecoboost, bought april 2018 with approx. 67,000 miles, currently at approx. 75,000 miles. I am reporting the sudden loss of accelerating power as the vehicle shudders and stalls both when moving with traffic or accelerating to enter or move with traffic. Multiple warning messages including the wrench light flash in the dash message area as the engine slows to idle with no ability to accelerate and comes to a stuttering stop. The first occurrence was three weeks ago and has happened no less than six time since - twice while accelerating onto the freeway (very busy, very fast traffic) and twice while crossing or turning in multi-lane intersections from stopped. Four of the six times resulted in my vehicle dying in and obstructing traffic with and me barely getting to the side of the road without an accident. I now shift to neutral to let momentum move the vehicle as I worm through traffic to the side of the road. Shutting off and restarting the engine clears or resets the message and sometimes "downhill assist not available" with the check engine light comes on. The check engine light has both stayed on or shut off on restart. I can then drive on the vehicle's own power, though the problem has repeated as soon as two minutes later, or not for days. I have not had to be towed and no accidents have occurred. The north carolina consumer's council filed a lawsuit against ford in 2015 which was settled with ford offering an extended warranty only on the etb (electronic throttle body) of certain model vehicles - all with the ecoboost engine, and multiple customer service actions (csa's) that have since expired. A few minutes on the ford forums online and it is apparent that this is a widespread problem with the ecoboost engine, and ford has offered several bandaids, but none until after the etb has failed and lives been endangered.

While driving there is rattling inside of the steering column that started a few months back. Now my alternator seems to not be working properly and the truck will only crank when I have all extras off (radio, AC, etc.) I also have to pump the gas for some reason for it to turn over completely. Otherwise it just dies. Never had a problem until last week when it wouldn't turn over at all. My battery is pulling 13.9 v and I have checked the connections. For a truck to be 3 years old and already need a new alternator appalls me. There is something else going on and the rattling in the steering column is somehow related to me having problems cranking the truck.
Throttle body problem at 36,999 miles. Went into "limp" mode with no warning while driving normally in a 45 MPH street with busy traffic. I was very lucky it did not cause an accident.
2015 f150 2.7l ecoboost 31,908 miles... Upon merging into traffic truck suddenly surges, followed by audible bang then abruptly loses all power "no driving conditions out of the ordinary, not under hard acceleration." warning lights on the dash light up and I have no control of vehicle. Luckily I was fortunate to not have much traffic around me at the time and promptly coasted into a deserted parking lot to call my dealership. I am afraid to drive my truck now for fear of causing an accident due to mechanical/electrical failure, I don't want to die and don't want to put anyone it that position either. Dealer replaced the throttle body and says its ok to drive yet the throttle body they used as a replacement is no different then the one that failed how can that be safe? I'd like them to trust a truck that ceased all essential operations (brakes, acceleration, power steering) with a wife and kids in the vehicle during morning rush hour in the fourth largest city in the united states with speeding drivers who don't pay attention to the road in front of them, then we will talk. This is a huge safety concern and a known problem with many other ford vehicles!!! Fix it before someone gets hurt or dies as a result! Do the right thing and hold the manufactures responsible its why we have the federal safety agency. How is there not a massive recall with the eco boost engines in regards to the faulty throttle body, anything less is unacceptable. Does someone have to die first?
Vehicle suddenly lost power while driving in traffic. Display slowed traction control malfunction, hill assist malfunction and engine trouble light illuminated. Loss of power steering and brakes. Once vehicle was shut off it then restarted a minute later as if nothing happened.
Brakes went out while driving. Brake fluid keeps disappearing. Brake fluid has leaked into the intake and caused massive amounts of smoke from the exhaust, the master cylinder failed at only 42k miles.
At times my 2015 f150 loses all power and go to a low power/ "limp mode" setting. Cautions received are (1) service advance trac, (2) hill descent control fault, (3) hill start assist not avail, (4) traaction control fault light. When this occurs, the vehicle goes to a very low forward power setting (<5mph), runs extremely rough to the point where the vehicle shakes aggressively. This problem is intermittent in nature, and yesterday was the final straw. This suddent oss of power occurred on a busy road and I nearly got rear ended. I immediately limped off the road and was able to get the vehicle towed to the dealership in castle rock, co. Currently I'm standing by for the mechanics diagnosis. Of note, I do see several similar write-ups of this problem on the federal safety agency site regarding the 2015 f150. Ironically, a similar occurrence (ref. Nhstsa id#11083485) happened right up the road from me in castle rock, co (4/5/18). I hope ford is aware of this extremely dangerous, recurring problem within its f150 fleet.
Something attached to the crankshaft cracked and now the entire engine is being replaced
Tl* the contact owns a 2015 ford f-150. While driving unknown speeds, the vehicle stalled. When the vehicle was restarted, it operated normally. The failure occurred multiple times. The vehicle was taken to billion auto ford of clear lake (3101 willow creek ct, clear lake, ia 50428, (641) 903-2299) where it was diagnosed that the throttle body and motor assembly failed. The vehicle was not repaired. The manufacturer was informed of the failure. The failure mileage was 84,129.

No hill assist flashed first, then traction control, then flashed check engine warning. Engine stayed on but in idle only with no throttle control, lost power steering too. Got to side of road. Pumped throttle. No response. Turned off. Restarted and cranked little longer than normal and started but idling rough. Turned off again. Restarted. Smooth that time. Dropped in gear and drove 4 hours home in sport mode at 75 MPH. No more issues last week till yesterday morning. Drove wife to dr on our 45 mile back country roads. Issue came back. This time ran rough when restarted. Then smoothed out. Did it 3 more times on way there. Which was 6 miles. On way home, reoccurred multiple times never getting it above 40 miles per hour before happening again. Called 3 tow companies, all were 2 hours out. Limped it home with flashers at 25 MPH. Had towed today to diffee ford in el reno. They said yes a tsb, but no ford not covering the cost of repair 61,340 multiple law suits have been filed complaints on the throttle body defective needing replaced leaving driver stranded.
Truck stalls due to throttle body actuator sticking. Vehicle becomes disabled/stalled and applies the brakes. Occurs without notice at any speed. Occurs on highway, city streets, and dirt roads. Requires throttle body replacement. Similar recalls did occur for the ford throttle body for other models and years (e.g. 13n03 program). Dealer indicates it is not covered under powertrain warranty (although it should be) and costs $600 to replace.
On freeway when lost acceleration. Indicator on dash said up hill assist not available and after clinking okay it then read service advance trac with the mechanic wrench showing. I'm on the shoulder of freeway, in park, and engine running rough as if on only two cylinders. I went ahead and put it back in drive and there was not throttle and trans would not kick in. Turned key off ready to call tow truck but went ahead and restarted the truck and issue cleared itself so we moved down the road. There is still an underlying issue, as I am told by my ford service writer, the etb needs to be replaced and from what I see online this is not an uncommon issue with the etb and f150. This is a major concern and I was fortunate I was not towing my travel trailer at time which could have had major issue getting to side of freeway safely without power, if not rear ended. Shouldn't there be a recall because of safety? Ford is selling f150 eb as quality tow vehicle although this could get someone hurt or even worse. Don't get me wrong, I am very pleased with the f150 eco boost and its performance but this issue needs to be addressed by ford! And not at customer expense!
