I had filed a complaint last year after a recall was put in place for 2011 F150 for the power control module and lead frame speed sensor and was told that my vehicle was not in the date range. I had the Ford dealership repair this at my expense and was told that I would be reimbursed by Ford if a recall was announced for my date of manufacture. Now that my vehicle is included in the recall, I asked the dealership to submit the paperwork so that I could be reimbursed and got a call back saying that Ford was not going to reimburse me for my expense. Can you assist with this matter ?

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.

On Monday January 6th I started my vehicle and let it warm up then when I tried to put my truck into reverse and when I put the shift lever in reverse the electronic transmission prndl display did not indicate the letter R for reverse and the backup lamps did not operate. After that I tried each gear and none of them were working so I put it into park and then back into drive it slammed into gear and then I was able to drive. The day before I got into my vehicle after it warmed up then put it into perverse and it did not go into reverse at all or drive. As a result I took it to midas in my town and they told me that there was a safety recall on my vehicle due to the codes and behavior so they advised me to take it to Ford dealership for it to be fixed for free. I did so and I asked about a recall and they reported to me that there is no recall and they want me to pay full charges this is a safety concern that can be taken care of by the dealership and I am missing work and out of the vehicle due to this delay and I'm still making payments on my vehicle that is not safe to drive.

2011 F-150 pick up has had 3 episodes of suddenly downshifting to first gear in highway speed & in town. Nearly caused an accident. Exactly as described in recall (16V248000), it has been towed to the dealer; absolutely unsafe to drive. Ford customer service told me it would not be included in the recall. Dealer wants $1400 to "fix" the problem.

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 contact owns a 2011 Ford F-150. While driving approximately 35 mph, the vehicle downshifted to first gear on its own. The contact pulled over and shut the vehicle off for approximately two minutes. Once restarted, the vehicle operated normally. The failure occurred seven times last week. The vehicle was taken to empire Ford of new bedford (395 mt pleasant street, new bedford, MA 02746) where it was diagnosed that the output speed sensor was defective and forced the vehicle to downshift to first gear. The manufacturer was notified of the failure. The vehicle was not repaired. The approximate failure mileage was 150,000.

The truck almost stalls or remains at idle regarding of gas pedal input. An intermittent "wrench" icon may appear in the instrument panel. Recycling the engine will temporarily clear the issue. This occurred each time after being stopped at idle at a traffic light. This is an extremely dangerous situation! I don't understand how this is allowed. The Ford dealer I called said the throttle body should be cleaned every 30,000 miles.

As I push hard on the gas pedal to accelerate, the engine misfires with a "clunk" feel and sound eld/heard in the cab. The engine continues for a bit and then happens again, and again until I release the gas pedal. This has nearly caused two accidents as I went to accelerate on the highway to 1) get out of the way of a driver who was ignorantly moving into my lane and 2) went to accelerate around an obstacle in the roadway and had to cut into oncoming traffic.

The speed odometer jumps around and the gears change sporadically. After having this check by my mechanic, they feel that it is the power train control module and speed sensor. They found a recall for this model F150 but it did not include the date of build on my vehicle. Recall 16S19. It is dangerous because you don't have any notice as to when it might act up and you loose power without any warning. It happens when driving on whywayans side streets, high and low speeds. It feels as if the gear is dropped from 5th to 1st and back.

Transmission jumps in and out of gear with no apparent relation to vehicles speed or throttle position. If the transmission decides to drop into 1st at sufficient speed to lock the drive wheels this is terrifying and inherently dangerous. Ford knows this condition exists on 6R80 transmissions but seems unwilling to widen the recall. Maybe someone needs to die before they address this. Its a miracle this hasn't lead to a loss of life incident yet.

2011 Ford F150 traveling at 65 mph straight down the highway the transmission seemed to slip out of gear and then down shifted to first gear causing the wheels locked up and loss control of the truck and ran off the road into a dry ditch. Research show a safety recall for this exact problem. Safety recall notice16S19/NHTSA recall16V-248. Ford Motor Company say my vehicle is not covered in this recall. Also Ford info for this recall states that 2011 F150 built at dearborn plant between the dates of February 11 2011 to September 8 2012 are covered in this recall. My vehicle falls into this category but is not covered. If I were to have been on a heavily traveled road this could have cause a serious accident

Output speed sensor (oss) failure (recall: 16N02). I was driving down a city street at approximately 45 mph, when the vehicle suddenly down shifted from fifth gear to first gear and then shifted back into fifth gear after approximately 10-15 seconds. Later that day, I was accelerating from a stop light when the vehicle felt like it had lost power and began to jerk when I pressed the gas. The speedometer stopped working, the info center displayed all dashes, the RPM's increased and the service advanced trac message displayed and the engine light illuminated. I had the codes from the engine light read and it came up as P0720 fault. My vehicle is experiencing all of the signs listed in the recall, but is not included. My truck was manufactured in the dearborn plant within the time frame of the recall dates. I have contacted Ford and the dealership and they could not explain why. I have attached a pdf of the recall.

The speedometer begins swinging erratically then the truck automatically downshifts from 6th gear to 1st gear at full highway speed (70 mph) causing the back tires to lock up and skid down the road. Extremely dangerous. Contacted Ford and they said they were aware of the problem and there is actually a recall on this very problem, but not for my truck since it was not within the recall dates by a few months. Took the truck to two different Ford dealerships and they said they don't know what is wrong with it, but could do the work outlined in the recall as long as I paid for it. See attached recall notice from Ford's website- Ford issues safety recall and customer satisfaction program for certain 2011-2012 Ford F-150, and 2012 Ford Expedition, Ford mustang and Lincoln Navigator vehicles in North America to update powertrain control module software and inspect for certain diagnostic trouble codes Ford is issuing a safety recall for approximately 202,000 2011-2012 Ford F-150, and 2012 Ford Expedition, Ford mustang and Lincoln Navigator vehicles for a potential issue with the output speed sensor on the vehicle's transmission lead frame. Under certain conditions, the transmission controls could force a temporary downshift into first gear. Depending on the speed of the vehicle at the time of the downshift, the driver could experience an abrupt speed reduction that could cause the rear tires to slide or lock up. This condition could result in loss of vehicle control, increasing the risk of a crash. Ford is aware of three reports of accidents and no injuries related to this condition.
