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 NHTSA 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.

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!

Vehicle lost power and flashed 3 warning messages. 1) hill start assist not available. 2) see manual. 3) service advance trac. In addition the service engine light stays on. All of this happened while I was making a left turn in traffic almost causing a collision. This is the second time it has happened. After first time dealer was contacted and service department reported no problems found. Appointment currently scheduled to look at it again.

While driving my truck it began to sputter and then the engine stopped completely. I was just shy of a busy intersection and had no power. The error message was "driver hill assist not available" which did not correlate to the problem at all. The engine light was also illuminated. After getting the truck to the Ford service center they found the electronic throttle body (etb) had failed. I have 50,000 miles on the vehicle. The shop said that they normally do not stock many parts but this was one they always keep in stock. The technician claimed he had seen 20+ failures in the fast year. Research on line indicated that there is more than 60,000 complaints in Ford vehicles regarding the failure of this etb. There was action initiated by the nhts and a recall was waived provided that Ford extend warranty for this part. That did not happen in my case. My bill was $604.92 more importantly I could have lost power in the middle of that intersection or during a long drive home where no cell reception was possible. I was lucky to have broken down in a town with a Ford service center before my 3.5 hour trip back to denver. Fyi, I called Ford customer care and they said that I was not part of a "customer satisfaction program"... interesting choice of words, because I didn't feel like I was part of anything at Ford nor were they concerned about this issue. In fact, they claimed it was not a significant problem.

Sadly, we feel we have purchased a lemon occasionally engine or transmission squeals/grinds, if accelerate too quickly/power up.,and now, on cold days [temps low 40S & under] hear rubbing/grinding whirring at left front tire" gets louder when depress brake, and can feel in brake pedal. Sound occurs during slow forward speed 2-40 mph, on gravel driveway or paved road. Scheduled service today for noise; they were more interested in fixing recall item [locks - rpr time 3+hrs], if they had parts in stock. Recall srvc completed [under 1 hr], and "no noise was heard." I requested further look for cause of noise, service advisor said quick lane would check suspension?. 2 hrs later, nothing seen, nothing heard, nothing repaired. As I pulled away from dealership, having signed off on service, the truck immediately began making the noise [funny serv advsr didn't hear when he brought truck around?]. I drove less than 1/10 mile back to dealership, took the service advisor for ride; at which point he acknowledged he heard noise, but tried to assure me it's a 'tire issue.' My husband and I believe otherwise - this is not tire noise, the noise never crescendos or changes pitch with increase or decrease speed, on gravel or asphalt, and we have never felt 'tire noise' in brake pedal. This noise/friction merely ceases after you've driven a few minutes [for now]. service advisor assured me I was not doing any further damage to truck, continuing to drive it without resolution to the problem. I asked him if I needed new tires, he said indeed not, mine are in great shape [original tires] with 63,000 miles on them [but it's a tire issue"]. something's up [similar concerns have been raised in forums on the internet- along with dealer dismissal/failure to resolve. We want our truck repaired [resolution of these mechanical failures] while it's under warranty, or we want a new vehicle.

While driving on the highway at 75 mph the truck shuttered violently and the engine shut down. Immediately it flashed a warning that the "hill climb assist" malfunctioned followed immediately by a wrench symbol notifying that service was needed then another warning about the advance trac system then back to the hill climb assist symbol. All of this happening while the car behind me is almost sideways trying to avoid me. I eventually made it to the right shoulder of the highway. As I read the various warnings it said to refer to the owners manual with regards to the hill climb assist. I turned the ignition off, pulled out the owners manual only to find a description of the hill climb assist feature. After waiting for about 5 minutes I decided to turn on the ignition. The truck started without issue and I continued home cautiously in the far right lane.

I would like to highlight safety concern on Ford F-150 intake throttle failures. I believe there has been a recall on this part for a different S/N range of Ford F-150. This VIN was not in the list. When this fails, you lose all power and truck goes into neutral. Was towing loaded trailer in 4 lanes of high speed interstate city driving. Almost was in serious accident. Ford customer service did nothing or indicate that they were going to look at S/N range impacted. I am a chief engineer at caterpillar. I understand the business of effective S/N and what is included in mandatory recalls. Their lack of action is a concern.

I have a 2015 F150 king ranch with the 3.5L ecoboost. It has 41,000 miles and never had an issue until yesterday morning and today around lunch. This was from yesterday 10/23/17: Hill descent control fault service advancetrac hill start assist not available I was pulling out onto a highway and the truck began shaking violently, moving very slow with no acceleration, power steering was lost, and the dashboard was showing all the above errors. Luckily there were no vehicles coming when I entered the highway and there was a place to safely pull off the highway. The truck continues to idle rough and shake violently. And today 10/24/17: I was driving down the interstate at 70 mph when the truck did the same thing as yesterday morning. I was able to pull off the side of the highway and shut off the motor. Once I restarted the engine, I was able to get it to the local Ford dealership. They say they have no idea why it would be doing this and have not heard anything from Ford or seen this in other F150's they have serviced. Update: The dealership claims the fix is in a faulty electronic throttle body and they replaced it at a whopping price of $770. A simple google search shows Ford has issues with etb's across vehicles of all classes and knows about it. In fact, some consumers seem to be involved in lawsuits against Ford because of their unwillingness to issue a recall before someone is fatally injured. These were scary, scary situations with my vehicle and thank god my wife and kids were not with me. There is obviously an issue and Ford needs to correct it at their expense.

Defective electronic throttle body causing "limp home" mode. I was driving home pulling my camper up a large bridge in Michigan during heavy traffic condition and the truck went into limp mode causing loss or power to tow the camper up and over the bridge. I alsmost created a serious accident with people slamming brakes behind my when I went from 70 mph to 0 in less then 150 ft. It has since happened several more times. I took it to a dealer and they knew exactly what the issue was and charged me $200 for deductible on the repair. I see all over the web that this is a known issue and Ford is doing nothing about it. When this occurs you feel a little lag in the performance when you press on the gas pedal for a second or two. The the hill decent warning will light up followed by the traction control fail light. The vehicle will then slow down to under 5mph and engine will re running very rough. You can shut the vehicle off and restart to get you further down the road but as times goes on this will continue to get worse and then happen every mile or so. Here is a great video someone did on the issue to capture the problem. Https://www.youtube.com/watch?V=cfdenhjmq84
