Truck had had a recall on the issues that we are having. Now we have been told that recall no long exist and that it was taken off of recall. We are having trouble with the transmission range senor circuit. Code P705 and it's hoing to cost almost $600 to fix. Is there still at recall on this?

While driving down the highway the fault code for timing chain P0016 came on and engine seized in the middle of the highway. I lost all power steering and brake power which caused me to almost collide with other vehicles trying to get off the highway with no power. After finally getting truck on the off ramp it took all I had to get it to stop at the intersection putting my life and the driver of the SUV at the intersection life in danger.

My check engine light came on, code scanned was P0016. The code scanner states it's an issue with the timing chain loosening over time. The truck has a very prominent rattle sound for about 2-3 seconds upon an initial start up in the cold weather. The other day I went to pass someone, and lost power in the engine and my truck would not accelerate past the car. Ford is aware of the issue, as people all over the country and Canada are having the same issue with 2011-2012 Ford F150 with the ecoboost engine. To me this seems like an obvious safety issue that Ford should take care of. Seems like an engineering flaw to me. The timing chain coming loose, and engine rattling like it's coming apart has to be causing damage as time goes on. The problem I had while trying to pass the car was on a lane 55mph road.

Engine completely turns off or dies and all instruments also turn off. Not able to steer or navigate the vehicle at all. It's completely dead. Also transmission lurches forward with no warning at low speeds causing you to slam on brakes or hit whatever is in front of you.

Truck will have severe intermittent stumble/misfiring on acceleration from 45mph+ in humid, wet or damp conditions. The vehicle shudders violently, bogs down, and check engine light flashes eventually becoming a solid engine light. This involves the engine shuddering when there is acceleration at highway speeds; this is very dangerous when trying to pass vehicles at highway speeds. Have my spark plugs and coils replaced after the following happened in damp and wet weather conditions. Make years seem to involve 2011-14 ecoboost trucks. From thousands of Ford forum posts, the trucks have an intercooler condensation problem that is causing poor performance and spark plugs/coils to fail early. Water and oil vapor/residue condensation is being sucked into the engine. People have had to take it upon themselves to find a solution by drilling a 1/16' hole in the low point of the intercooler driver's side to drain oil/water condensation/residue or install a $400-$500 oil catch can separator which Ford should be offering to owners with this problem. Ford should own this problem and issue an appropriate fix like the oil catch can installation or confirm with its owners that it is ok to drill a weep hole in the intercooler. Not the cheap fixes I have seen like tsb 13-8-1.

The contact owns a 2011 Ford F-150. When the accelerator pedal was depressed, there was a sudden loss of engine power and the vehicle hesitated to the point that it could stall without warning. Capital Ford (3660 S carson St, carson city, nv 89701, (775) 882-5353) was made aware of the failure and advised the contact to schedule a diagnostic appointment. The vehicle hesitated while at a stop, during acceleration, and while making a turn, which caused the contact to have to downshift. Customer service campaign program number: 15N05 (electric vacuum pump recall) was referenced as a possible cause of the failure. The manufacturer was notified of the failure. The approximate failure mileage was 110,000.

Bad transmission leadframe assembly as previously identified by Ford in a recall causing vehicle to lose power at 65mph requiring vehicle to be stopped and restarted; Ford has identified issue as 16V-248 but told me that my vehicle missed the campaign as my vehicle build date was 11 days prior to their recall dates; however, my vehicle was built at same plant (dearborn) and had same identical error codes for problem; Ford rep at 866-436-7332 told me that although problem seems the same nothing can be covered; to resolve cost me $751.27. Always occurred while vehicle in motion.

While driving my 2011 F150 I got of I99 at the tyrone exit. While slowing to a stop at about 35 mph the truck shifted from 5thgear to 1st which cause the wheels to squawk and slide almost causing me to lose control, I pulled over in the bk parking lot shut it off an restarted once I put it in gear to drive it showed I was in 5th gear so I shut it off again waited a few minutes S td started it again and this time it was in 3rd so I repeated. The next time it was in first so I drove home the back roads to be safe as I got up to speed it started to act up again the speedometer show I was going 0mph but I was going 25mph again the truck slammed in an out of gear I took it to my local Ford deal they diagnosed it as a lead frame hope this fixes the problem as I'm scared to drive my truck. I do have videos of when its acting up but I cant figure out how to upload them.

Vehicle downshifts while driving abruptly and without cause. This has occurred at highway and city speeds as well as with and without a trailer in tow. The front end still is all over the road, following tire replacement, brake replacement and alignment.

The truck looses power while driving down the road. Most of the time I have been driving as a slow rate of speed 20-35 mph. The engine continues to run and the wrench light comes on the dash. The transmission receives no power and the truck will only coast forward. Immediate solution is to pull over, shut the engine off and restart. The truck then has power. The problem may repeat itself within miles or it may not repeat for days/weeks. This happen 18 months ago, 4 months ago, and 2 days ago.

Had complete brake failure. Was able to get the truck stopped. Saw it was 2 pints low on fluid. Added fluid, drove towards my auto shop, had to stop to fill the brake fluid again (the light went on this time). Did this a few times. Just before I got to the stop, the truck blew out some smoke, chugged, and the motor seized up. Towed the truck to the shop, they found out the master cylinder leaked and the vacuum lines sucked the brake fluid out of the master cylinder and dumped it into the cylinders in the motor and this blew my motor. I hear there is a recall for this on 2014 F-150S but not on the 2011. Terrible design. A brake problem should not blow up my motor.

My truck is having the issues outlined in the NHTSA investgation PE13018. In some cases in rainy or humid conditions the engine misfires (sometimes without any codes) and loses power when accelerating. The engine sometimes than won't shift out of a lower gear until it is shut off and restarted. The Ford tsb (12-10-19) and related Q&a provided to the NHTSA has a fix but because the dealership has not repeated the issues (it hasn't been humid out and they aren't doing it under highway or open throttle speeds). We have given dates, experiences and codes to the dealership (including ones in the tsb). But as they can't recreate it in the service bay, they won't make the fix.

The contact owns a 2011 Ford F-150. While driving approximately 10 mph, the contact heard a loud bang sound from the engine compartment. The contact pulled the vehicle over to the side of the road to find that coolant was leaking onto the ground. The vehicle was towed to an independent mechanic and it was determined that the coolant was leaking into the oil and there were also metal shavings in the mixture. The dealer and manufacturer were not notified of the failure. The vehicle was not repaired. The approximate failure mileage was 94,000.

Driving 70 mph when 2011 Ford F-150 while driving in cruise control with A/C on lost all power..........and a tool displayed on dash. I was able to pull over on-side of interstate luckily.......turned off vehicle waited a few minutes and re-started with no further issues. I'm concerned this is similar to other issues Ford products have been having. Need answers before your vehicle hurts my family!!!
