The contact owns a 2014 Ford F-150. The contact stated that while driving at an undisclosed speed, the check engine warning light, the wrench warning light, and the air bag warning light illuminated. In addition, the speedometer failed to function as intended. The speedometer indicated 0 MPH while driving. The contact pulled over to the side of the road and turned off the vehicle. After the vehicle was restarted, the wrench warning light was no longer illuminated. The contact continued to drive, and while driving at 45 MPH, the vehicle failed to accelerate as intended while depressing the accelerator pedal. The wrench warning light intermittently illuminated, and the air bag warning light illuminated. The contact stated that the vehicle failed to respond as needed while driving. The vehicle was taken to a collision center. The contact was provided the following codes: P1500-00, P0722-00, P0721-00, P0304-00, and P0151-00. The contact stated that the codes were cleared while at the collision center. The vehicle failed the emission test. The vehicle was taken to an independent mechanic who diagnosed that the steering wheel sensor had failed, and the sensor was replaced. The contact stated that on the drive back to the residence after leaving the independent mechanic, the check engine warning light, the wrench warning light, and the air bag warning light were illuminated. In addition, the speedometer failed to function as intended. The vehicle was taken back to the independent mechanic, who diagnosed that the transmission output shaft speed sensor and the powertrain control module had failed and needed to be replaced. The vehicle was not repaired. Most recently, the contact stated that while the vehicle was stopped at a traffic light, once the contact removed the foot from the brake pedal, the vehicle failed to move.

I had the OSS software recall completed a few months ago. Software fix is suppose to prevent automatic downshifting to 1st gear when traveling in higher gears. I am now having slipping/engine shudder when accelerating in higher gears. More than likely the lead frame will need to be replaced and my independent mechanic has said this should have been the fix initially, not just a software update. (Same models from 2011-2013 have had this recall implemented, but the 2014 has not been included for some reason.)

I experienced an abrupt downshift while driving ~60 mph and the speedometer/odometer quit working, an orange wrench light appeared, and the engine light came on. My vehicle had Ford recall 24S37 open, which relates to the OSS and a symptom is an abrupt downshift. I took the truck to the local Ford dealer. They indicated that there were no codes showing- which I am suspicious of given the issues I experienced and I had a private reader read the truck after the recall programming and it did show an O2 sensor code- P0131 and at one point a P0722 code. The Ford dealer performed only the programming as part of the recall. After the recall programming, the truck experienced additional abrupt downshifts. I had to take the truck in again and pay for them to read the code even though I had the codes. After reading the code they indicated that the lead frame needed to be replaced. I had this replaced out of pocket (~$1138.21) and the O2 sensor for a total invoice of $1521.85. I contacted Ford to express my concern and frustration- case #CXH05849514. It appears that the recall programming was not effective in eliminating the problem.

Took in my vehicle to my local Ford Dealership after I experineced sudden downshift of the transmission and getting stuck in 1st gear. I asked for a reantal vehicle or a loaner to which they said, it would depend whether or not there would be any PCM related codes that came back after connecting the car. According to them no codes came back, and explained to me that, that being the case that they would just need to reprogram my PCM. The next day I went and picked up my truck, and after just about roughly 7 miles into driving, I started experiencing sudden downshift again and my truck started slowing down rapidly almost causing an accident and getting rear ended. I was able to pull over and noticed this time my truck had gotten stuck in 4th gear. I was able to drive it back to the dealership and left it parked in the their parking lot as it was after hours at this point. The very next morning by 7:30AM I was at their service desk explaining what had happened the night before after picking up my truck from them. They refused to give me any further service as they said that they had already completed the service related to the 24S37 recall, and that if I continued to experience issues, that it was a completly unrelated issue and if I wanted to get it diagnose and repaired that it would be out of pocket. After doing more reserach online, I came to find out that on some of this recall issues related to 24S37, in some cases the dealership would have to replace the entire Lead Frame which holds the Transmission output shaft speed sensor which goes bad and causes the transmission to go crazy and thus the downshifting, and in other cases they don't have to replace this part. In my case, while there were no other codes that showed, they determined that only a reprogramming was necessary. However, given that I continue to experience the same sudden downshift issues, I suspect that it is a bad output shaft speed sensor which should be replaced under the current safety recall.

There was a sudden downshift at 50mph and a wrench icon showed up on my truck. I used on OBDII scanner and the codes p0706 and p0707 showed up. My safety was put at risk because I could have been hit in the rear and my rear tire locked up. I got the repairs done for a leadframe install. Is there any way I can get reimbursed for the repairs made, because this was once a recalled issue.

2RQ24005 · Unintended Transmission Downshift
Opened Mar 27, 2024 · Closed Jul 29, 2024
Status: closed (inferred from source dates) · Power Train:automatic Transmission:control Module (tcm/pcm/tecm)
In September 2016, Ford Motor Company (Ford) issued safety recall 16V-248 which included certain model year (MY) 2011-2012 Ford F-150 vehicles equipped with 6-speed (6R80) automatic transmissions. This recall was in response to allegations of unintended, unexpected vehicle transmission downshifting to a lower gear without warning, often accompanied by temporary rear wheel lock-up, increasing the risk of a crash and/or injury, and included approximately 153,581 vehicles. Ford identified the root cause of the unintended, unexpected vehicle transmission downshifting to a lower gear to be intermittent signal loss from the transmission’s Output Shaft Speed (OSS) sensor due to solder joint cracks on the OSS circuit board as a result of manufacturing process issues. The OSS sensor is mounted onto the molded lead frame and transmits changes in transmission shaft speed to the Powertrain Control Module (PCM). The remedy program described in safety recall 16V-248 involved reprogramming of the PCM to prevent unintended vehicle transmission downshifting from occurring. In December 2017, the Office of Defects Investigation (ODI) opened a Recall Query (RQ17-010) to assess the scope and remedy effectiveness of safety recall 16V-248. As a result of this ODI investigation, Ford issued safety recall 19V-075 to expand the scope of 16V-248 to include MY 2011-2013 Ford F-150 vehicles equipped with 6-speed (6R80) automatic transmissions and included approximately 1,263,051 vehicles. The remedy program described in safety recall 19V-075 involved reprogramming of the PCM to prevent unintended vehicle transmission downshifting from occurring. In June 2019, Ford issued safety recall 19V-433 as the remedy program used to service MY 2013 Ford F-150 5.0L and 6.2L vehicles in accordance with safety recall 19V-075 did not contain the necessary updates to prevent unintended vehicle transmission downshifting from occurring and included approximately 107,857 vehicles. On March 27, 2024, ODI opened this Recall Query (RQ24-005) to investigate the scope of the above-described safety recalls. At the time that this investigation was opened, ODI had received 86 Vehicle Owner Questionnaires (VOQs) reporting allegations of unintended, unexpected vehicle transmission downshifting to a lower gear without warning, often accompanied by temporary rear wheel lock-up, in MY 2014 Ford F-150 vehicles. As a result of this Recall Query, Ford filled safety recall 24V-444 on June 14, 2024, to include MY 2014 Ford F-150 vehicles and expand the scope of safety recalls 16V-248, 19V-075 and 19V-433. The remedy program described in safety recall 24V-444 involved reprogramming of the PCM to prevent unintended vehicle transmission downshifting from occurring and included approximately 552,188 vehicles. In its May 2024 response to ODI’s information request, Ford concluded that a predominant root cause for the intermittent OSS signal loss has not been identified outside of the original safety recall (16V-248). Ford’s investigation also concluded that the primary causes of the defect in MY 2014 F-150 vehicles were related to the molded lead frame and the control assembly transmission main. In the May 2024 response, Ford identified 2,184 total reports that described unintended vehicle transmission downshifting and rear wheel lock-up events; 1,441 warranty claims and 743 reports from consumer complaints, field reports, consumer surveys, and lawsuits/legal claims. Note that the values presented here and in the table above represent the total number of reports which can include a single consumer with multiple reports of the same event as well as a consumer with reports of multiple distinct events. Of the 1,441 warranty claims, 551 warranty claims involved repair of the molded lead frame (38%) and 509 warranty claims involved repair of the control assembly transmission main (35%).

On May 23, 2016, Ford Motor Company (Ford) submitted a Defect Information Report (DIR) to NHTSA regarding a master cylinder defect that could result in loss of the front brake circuit in approximately 225,012 model year 2013 through 2014 Ford F-150 vehicles equipped with 3.5-liter GTDI engines and built at the Dearborn Truck Plant from August 1, 2013 through August 22, 2014; and the Kansas City Assembly Plant from August 1, 2013 through August 31, 2014 (NHTSA Recall #16V-345, Ford Recall #16S24).Ford indicated that the rearmost cup seal in the brake master cylinder may roll, resulting in leakage from the brake fluid reservoir to the brake booster.According to Ford's DIR, Depending on the amount of brake fluid loss from the brake master cylinder into the brake booster, the driver will experience an audible chime, message center alert, red brake warning light in the instrument cluster and may begin to experience a change in brake pedal travel and feel.In the event that a loss of brake fluid is substantial enough to reduce brake function to the front wheels, the driver may experience longer pedal travel, increased pedal effort, and extended stopping distance, increasing the risk of a crash.Full braking function would remain in the rear wheel brake circuit.Ford's recall will replace the master cylinder and, if the master cylinder is leaking, also replace the brake booster.Seventy-three (73) of the complaints received by ODI contained vehicle identification number (VIN) information required to determine date of build and recall applicability.ODI's analysis found that 66 complaints to ODI and 278 complaints to Ford involving vehicles built in the range covered by 16V-345, resulting in an overall complaint rate of 152.9 incidents per 100,000 vehicles.Twelve (12) crash incidents were reported, including 11 with VIN information.All 11 crash incidents with VIN information reported involve vehicles covered by Ford's recall.ODI's analysis identified 7 ODI complaints and 36 Ford complaints in the 194,139 subject vehicles built outside of the build range for 16V-345, resulting in a complaint rate of 22.1 incidents per 100,000 vehicles.Ford indicated that warranty return analyses identified issues with minor internal leakage between circuits due to internal contamination caused by supplier assembly plant cleanliness concerns in these vehicles.Ford assessed the internal leak condition as an early-life condition with minimal safety risk that does not result in loss of fluid or circuit failure.ODI will continue to monitor complaints in subject vehicles not included in 16V-345.No complaints have been identified in MY 2013 through 2014 Ford F-150 vehicles equipped with other engine options.The recall action initiated by the manufacturer appears to address the safety risks identified by this investigation.This preliminary evaluation is closed.The ODI reports cited above can be reviewed at http://www-odi.nhtsa.dot.gov/owners/SearchSafetylssues under the following identification numbers:10870768, 10870747, 10870511, 10870395, 10870055, 10869981, 10865843, 10865521, 10865342, 10865043, 10864862, 10864714, 10864360, 10863982, 10863527, 10862333, 10862047, 10861735, 10861190, 10860378, 10860118, 10855381, 10855356, 10854785, 10853751, 10853295, 10853012, 10852349, 10852134, 10852037, 10851317, 10851268, 10851109, 10850015, 10849862, 10846488, 10846335, 10846193, 10846006, 10840414, 10840377, 10839994, 10839985, 10839981, 10839833, 10839825, 10839816, 10838782, 10838510, 10818273, 10817706, 10809601, 10788886, 10788369, 10785526, 10779854, 10776834, 10766291, 10762034, 10761412, 10760663, 10758997, 10750065, 10749886, 107
