Speed Sensor problems of the 2011 Ford F-150

The most recent incident resulted in transmission having a harsh downshift to first gear causing vehicle to jerk and engine revs up. This has happened several times in the past including a few days before taking it in for the recall repair in 2019. ( recall 19v -075). This problem, according to Ford, is due to intermittent failure of the output speed sensor ( part of the molded leadframe in the transmission). Two latest incidents occurred on a city street. Have had at least one occasion on an expressway where vehicle had very jerky transmission shift while in cruise control. Have complained about this to Ford and took the vehicle in on two occasions ( see attached invoices). The problem has never been resolved and no warning messages or trouble codes have been found during the repairs. Ford issued an extended warranty coverage ( program # 19n01) on may 2019 and my vehicle still qualifies. I took the vehicle in this week to request they replace the molded leadframe since the problem is still present. They refuse to replace the part because they say no trouble codes are present. I have found others on Ford forums who say they have the same problem and they also have no trouble codes stored either. Ford needs to acknowledge that the lack of trouble codes does not ensure the problem is not present. I continue to have concerns that my family's safety and others is jeopardized by Ford not agreeing to take responsibility and making the necessary repairs. They themselves say in the recall notice that "this condition could result in a loss of vehicle control, increasing the risk of a crash. ".

I have had this happen twice but the speedometer doesn't work and won't come out of 1st or second gear. Luckily both times it was in my driveway after I started it. Codes p0720 and p0722 came up both times which is the speed sensor problem. There is or was a recall on this year and make, model and I need it fixed please. Thank you.

Molded lead frame and oss replacement. I was not notified of the molded lead frame recall 16n02. I experienced the electrical issue described in the recall in my driveway. My dashboard lit up like a christmas tree and would only drive in first gear. I drove to a mechanic that was closer than the Ford dealer and was off of back roads so I could drive in first gear. I paid for the repair. I recently received a recall notice 19s07 which is for programming the oss sensor. I asked to be reimbursed for my repair and I was told no by crescent Ford & trucks. They said 19s07 is for programming only. I believe Ford should reimburse me for the lead frame, connector, automatic transmission fluid, and the speed sensor.

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.

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 ?.

While driving my transmission changed gears speraticly from 1 to 2 to 5th back to first causing my rear end to lock up temporarily then service light came on. The meters showed that it was the output shaft speed control sensor. I was in waynesboro, ms on john perry mcmichael rd. This problem had occurred in many of the 6r80 transmissions of this same year.

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.

Driving on highway at 70mph, I saw my speedometer momentarily drop to 40mph. It did it again about 15 seconds later, and downshifted to about 4th gear momentarily. About a minute later, still at 70mph the speedometer dropped, and the transmission downshifted to 1st gear! my rear wheels locked up, and I lost control, and fishtailed for a few seconds. Luckily I had taken a half day vacation and was not in rush hour traffic. Still other cars had to swerve to keep from being hit. The dearlership was able to reproduce the problem, and replaced a moulded plastic module made by continental that I think contained the transmission speed sensor. So it appears that when the transmission speed sensor signal is lost, the failure mode is to downshift to 1st gear no matter the speed of the vehicle.
