At 70K miles, my timing chain stretched causing me to have to have it replaced costing $3200. This is a known issue by Ford and there is an official technical service bulletin for this issue. This issue is dangerous and caused serious acceleration issues while driving almost causing a wreck as I tried to accelerate up hill.

- Bloomington, IN, USA

While driving, I noticed that I was having to push on the accelerator harder to get power. I came to a stop at a stop sign and waited for an opening to turn left at the intersection. When I started to turn left, the truck started to accelerate and then the engine sounded like it revved up but there was no power or speed increase and a simply coasted out into the middle of the road. The traffic coming from the left was coming up over a hill and I was very lucky that they were able to stop before hitting me. The truck was able to pick up speed down hill, but lost speed quickly going up hill. I could see this being a dangerous issue when crossing a busy intersection or trying to pass. I took the truck to the dealership and was told the timing chain stretched. The truck had only 74000 miles.

Loss of power while driving, depressing accelerator does not power the vehicle, speedometer needle not working. Once able to steer vehicle safely to side of road and turned off and back on, vehicle responds as expected. Happened twice already, on 8/24/2017 and 8/29/2017.

While driving on the highway I experienced severe reduced engine power during a acceleration for an attempted pass. An issue Ford was aware would happen without the deflector plate due to design flaw! no alert to the owners that it was a potential concern, bring the vehicle in for a check - no word at all! if there was a known problem with their turbo design leading to compounding premature failure, why wouldn't they let the owners know" the dealership would have had ample opportunity to inform me of the issue if that was their intention as I visit regularly

I have a 2012 Ford F 150 with 66,800 miles on it and have changed one of the turbos. About may of 2017 I noticed a shutter and shaking of the engine, then lose of power, failure to accelerate on hills, the vehicle would down shift for no reason or you had to put the gas peddle to the floor to even move then it would kick in and cause the wheels to spin. I took the vehicle to my local Ford dealer to diagnose the check engine light. I was told that one of the turbos needed replaced at a cost of $1800, well I had it replaced at my own personnel garage and after driving the vehicle 5 miles it had all the same issues. I called the Ford hot line 3 times asking what they will do to fix my truck, I was told the warranty ran out at 60000 miles, I explained the vehicle just started doing this and I did not haul anything and only drove it about 12000 miles a year, this should not be happening. This is very dangerous trying to drive a vehicle that losses power then accelerate without warning. Ford told me there were some recalls on the 3.5 L eco-boost engine but not on my truck. I have been a Ford man for over 40 years, I bought this truck brand new in 2012 and Ford will not do anything but charge me more money, I do not beat my truck I baby it, I take very good care of my vehicles, this is not my fault it is poor engine designee and Ford should fix this for me because as I said it is a safety hazard for me and anyone else on the road with this engine.

- Bonnerdale, AR, USA

When I start the truck the engine light is on, while driving the truck stalls and looses power and the tool sign comes on in read out window. I have to pull over and put the truck in park and restart it. This happens every 100 yards or so. I under stand this is an ongoing problem with the 2012 F150 Ford trucks. I can't understand why the want have a recall. I understand they need to add a deflector shield under the motor. It's very dangerous when a vehicle looses power while driving down the highway.

Engine rattle upon startup, 3.5L eco boost engine. Usually only when the vehicle has sat for some time.

- Michigan City, IN, USA

The contact owns a 2012 Ford F-150. While driving approximately 55 mph, the engine shuttered and the vehicle lost power. The vehicle was coasted to the side of the road, shut off, and restarted. The engine warning indicator illuminated and flickered occasionally. The vehicle was taken to the dealer (crossroads Ford in prince george, Virginia) who stated that nothing was wrong with the vehicle. The manufacturer was made aware of the failure and did not assist. The failure recurred and a popping noise was heard from the engine. The vehicle was pulled over to the side of the road. The contact looked underneath the vehicle and noticed oil dripping from the engine. The low pressure oil warning indicator also illuminated. The vehicle was towed to the dealer (sheehy Ford in ashland, Virginia) where the technician found pieces of metal from the engine and diagnosed that there was a hole in the engine. The failure was not repaired per the contact's order, pending a discussion with the manufacturer. The failure mileage was approximately 15,000.

3.5 ecoboost engine 75,000 miles, engine noise on startup and check engine light registering a P0016 crankshaft/camshaft position sensor, and goes into "limp mode" with loss of power and poor acceleration. Dealership states this is a recognized issue with the timing chain and tsb 14-0194 addresses the issue. Dealership states this is a $ 1,500- $ 2,000 repair and is not covered by Ford. Timing chains should last longer than shock absorbers.

The truck will automatically downshift by itself while driving. It is experiencing the exact same issue that is a part of recall 16V248000 but our specific VIN isn't a part of it at this time. It is not safe to drive as at any speed above 45 it downshifts.

- Portage, MI, USA

Noticed small amount of coolant on the ground. Started to notice over the next couple days larger amounts of coolant after driving. Took truck into dealer and the water pump had already gone bad. Was under warranty so it was replaced for free.

Ecoboost engine in this model is known to have functioning problems when it warms up and you are on the highway at highway speeds. The truck will start to lose power and almost feel like it will stall at highway speeds. It is a known problem with Ford and well described on many auto forums on the web. I took my truck in and they are charging me for a "fix". this is a documented problem which Ford even has as an internal service bulletin about. I have never been charged by any other auto company when they come out with a service bulletin except for this company. More importantly I had to explain what is on the web about this to the service tech at the Ford dealership--like a patient explaining to his surgeon what the problem is and how to operate on him to fix it---very odd and concerning. Either way, it is very possible to get into an accident on the highway---and maybe it has already happened. My son primarily drives this vehicle and has been mentioning it to me for months. I passed it off as bad gas or the way he was driving. We had taken it to a Firestone dealer for an oil change and they recommended we take it to the dealer.

My 2012 F150 ecoboost 3.5 studders severely, hesitates, and will not accelerate when trying to pass on the highway. The dealer has bulletins addressing this. I have been told multiple repairs that now are not under warranty including cac cooler deflector, spark plugs, catalytic converter, cam phasers, timing belt, and many others. The truck started this problem and may now require the turbos be replaced. This is a very common problem with this motor and Ford is well aware of the issue. This defect should be covered by Ford.

- Temperance, MI, USA

When starting my 2012 F150 I turn the key and there is a delay and then it starts don't think that is right I get 15.6 miles per gal on my 3.5 eco-boost and kicking in the passing gear I loose power and eng. Light comes on 3 times this has happen all times I pull over and shut truck off and restart light goes out.

- Parkman, ME, USA

Already had timing belt replaced at 84,000 miles. Now at 85,600 miles I was on ramp merging onto hwy. When a blinking engine light came on, loss of power, and truck shook like crazy. I felt like it was a poltergeist. Took next exit off and came to a complete stop. Engine light went off and truck acted normally again. Damp conditions. Not liking all the complaints I have read and certainly not liking the sporatic unknown. I think I'll be trading this $50,000 lariat in for something else. Ford needs to react, that was a scary situation on the freeway with trucks bearing down on me.

The ses, service engine soon, light came on. I noticed my truck lacking power and taking longer to shift gears when accelerating. It become less of a smooth shift and more jerky. When traveling on the highway at ~70 mph, the engine would not hold 6th gear. It would drop to 5th and 4th gear, until I gave it more gas. It would reach 3500 RPM's at times before shifting which was not normal. I also noticed starting in the fall of 2016 a short loud abnormal noise at cold start. After researching these issues, this led me to tsb 14-0194, code P0016, dealing with the 3.5L ecoboost engine. I took my truck to my local dealer and this was the issue. I have been the only owner of less than 5 years and was at 75,500 miles, out of the 60,000 mile warranty. I just had the repair done, costing me $3600. The repair included parts listed in tsb 14-0194 as well as timing belts, additional gaskets, seals, guides, tensioner, cam, sprocket, gear crankshaft, among others. I question how this known issue of timing chain stretch with the tsb is not a recall. This problem can cause an accident when accelerating on to a freeway. It can also cause an accident by suddenly downshifting while driving. I am glad my truck is fixed, however did not like the price tag. I fear that this known issue will lead to a deathly accident and it is unfortunate that a recall has not been issued yet. I hope this post helps make a change, saving consumers a costly repair and even someones life from a future accident.

After my Ford F150 with the eco-boost engine is out in the rain, when I accelerate on the road the truck sputters and shakes and there is a lose of power. This has happened since I bought the truck new.
