2016 Ford F-150 Speed Control & Cruise Problems

Today I was driving my truck at 55mph on a local highway and all of the sudden I felt/heard/experienced a massive clunk out of nowhere - almost like the truck tried to downshift into 1st or something similarly jarring. It only lasted a second, and then I got a dash light on that said Service AdvanceTrac. Based on the service codes I'm seeing (two of them that are both UO100 codes which indicate loss of communication), I did some research and found out about the OSS sensor issue and think that's what is going on with my truck too. Unfortunately I'm not sure if I'm going to be able to get a Ford dealership to do anything about it since there isn't an official recall, and I'm afraid to keep driving it as this is likely going to keep happening - but fixing it myself is going to be expensive I think. It is available for inspection upon request. I felt that my safety was and continues to be at risk - downshifting into 1st gear, or whatever that was, while driving high speeds is dangerous and could potentially significantly damage my vehicle and myself. I have not taken it anywhere yet to be reproduced or confirmed - just plugged my scanner in and did a bit of research. No one has inspected it.

while driving at about 50 mph, the truck will go from 6th to 1st, and lock up the rear end briefly. I'm the mechanic filing this for my customer, seems to me, its the lead frame failing in the trans, and they have done nothing about it, customer says ford worked on this transmission, the only updated part i found was 1 extra magnet. old part number for the lead frame, and a known failing lead frame #, I'm pretty sure you guys have a open case for these trucks.

My transmission started down shifting on its own while driving one morning and the check engine light and wrench light illuminated. I took it to the dealership that afternoon and had the conductor board replaced. They said it was the speed sensor that malfunctioned.

Turn Signals, Speed Control Radio Functions, Windsheild Wipers STOPPED WORKING! It effects people in front ,back or side knowing what I am doing so they can react like turning in any direction , My vision is blocked during rain or snow and will cause an accident harming me or others . ' No warning lamps came on when problem happened ! ' Problem has been confirmed by a Qualified Mechanic !

When traveling at around 70-75 mph the vehicle will downshift to 5th gear and vehicle speed drops as well, without warning. This causes the vehicle to not want to excel until it comes to a complete stop or turns off and then turns back on.

The truck wrench symbol showed up. The second time it showed the truck didn’t seem to shift correctly. It hesitated to progress in speed like usual, creating a situation that I could have been hit by cross traffic because it was moving at a lot slower speed than expected for trying to accelerate. I had ford inspect my vehicle for what might be working incorrectly and they couldn’t diagnose the issue. It has not acted up since I had it looked at. As far as I know they couldn’t determine what created the shifting problem and no course of action to repair it was taken.

Unexpectedly shifting down to first gear during any speed

Driving down the expressway at 70 mph, vehicle gear light indicators started to flash between gears, and vehicle abruptly entered limp-home mode and downshifted to 3rd gear, causing the vehicle to aggressively decelerate to the point of the back wheels squealing. If another car was in standard following distance, it would have been a certain accident.

I was driving on [XXX] in the City of Chester, PA, at the merge with [XXX]; this is a high traffic, multi-lane, confusing merge for drivers unfamiliar with the road ( I know it well). My truck just shut down, and I had to put it in neutral to re-start it. I knew there was a problem, because it had previously shifted roughly at times. But I just had it inspected at the Garnet Ford dealership, told them about the problem, and they could not diagnose/fix it. It passed inspection, and I thought that it would iron out, but instead, I could have been in real trouble. I took it to another mechanic, and they told me it was something else. I paid $1,206 and the problem was still there. I finally think I figured it out by going on a chat with other Ford owners. I just made another appt. with Garnet to do the repair. This should be re-called. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The 6r80 transmission lead frame cause my truck to slam into first gear when going 55 miles an hour.

This has happened quiet a bit I'm driving on the highway going 75mph set my cruise control and I go to pass or up a hill and the truck engine and tranny light start flashing the truck losses power it won't go even when u push petal to floor it also spits and sputters if u turn of the cruise control put the car n neutral and shut it off then back on it stops this seems to b an constant thing there's no engine light or tranny lights on after it happens it

2016 Ford F150 Platinum 5.0L V8 with automatic 6R80 transmission. Erratic gear shifting while driving. Sometimes not getting out of/stuck in 3rd gear and sometimes not downshifting below 3rd gear. Orange wrench or illuminated MIL light came on followed by a solid check engine light. Took it to dealership - DTC P0720 and P0722 appeared. Dealership tech states that he reprogrammed the PCM and output shaft speed sensor, and that the next step is to drive it and see how it does and if it didn’t fix the problem then he will have to change the molded leadframe. This issue is exactly the same issue as the customer satisfaction program 19N01. The safety concern is I don’t want to drive it around, waiting for the leadframe to fail one day while I’m driving down the freeway with my family in 6th gear and have the truck shift abruptly to 3rd or 1st gear and lose control. This issue is exactly like the 19N01 with the same 6R80 transmission.

Transmission will down shift to first while driving on highway. Code come up for transmission speed sensor short. Same as in the 2011 to 2013 models. That tab should be extended to later models. It is unsafe and could cause an accident/ death in high speed driving.

The contact owns a 2016 Ford F-150. The contact stated that while approaching a stop, the brake pedal was depressed, but the vehicle accelerated to unknown speeds. The driver continuously depressed the brake pedal, but it failed to respond. The driver crashed into a mailbox, brick decorations, a stop sign, a golf cart, a gas line, and a tree. The driver pulled the emergency brake, and the vehicle stopped.  There were no warning lights illuminated. The vehicle was towed to a collision center. The contact sustained injuries to her hip, but medical attention was not provided. A police report was filed. There was no reported fire or air bag deployment. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 30,000.

Driving up a hill on interstate 70MPH when an engine light with Hill Climb Assist disabled error came on. Accellerater shut down and had to coast to side of road. I shut vehicle off and started back up and was able to proceed till I got off highway and proceeded up another hill and same thing happened stalled and came to a stop. I found dozens of other F150 owners having the same problem stalling in the highway. All the posts indicate they had a bad "Throttle Body". Ford has had similar problems on other models but doesn't aknowledge this one.

Transmission refused to down shift from 5th gear or go over 55 mph. Truck began to shutter and the powertrain wrench error code appeared on the dash. Truck also began to have a clanking sound. The truck jerked violently at 50 mph causing the safety of myself and 3 other passengers at risk. The Marshal Mize Ford dealer in Hixson, TN confirmed the transmission lead frame was faulty, just like the Ford recall for the 2011-2013 F150 truck.

The contact owns a 2016 Ford F-150. The contact stated while driving 55-60 MPH, the vehicle went into LIMP Mode and lost motive power. There was no warning light illuminated. The contact was able to veer to the side of the road. The contact turned off the vehicle and restarted the vehicle after a while. The contact continued driving; however, the failure recurred several times while driving. The contact was able to drive to the residence. The vehicle was towed to the dealer, where unknown repairs were performed. Additionally, the contact stated while driving 20 MPH on a slight incline and depressing the accelerator pedal, the vehicle failed to respond. The message "Hill Assist Not Working" was displayed. The contact stated that she reversed at 3 MPH to her residence. The contact stated that the failure recurred several times while driving on a level road. The contact veered to the side of the road and shifted into Sport(S) mode, and was able to drive 30-35 MPH. The vehicle was taken to Rocky Mountain Yeti Pinedale Jeep RAM (153 S Entertainment Ln, Pinedale, WY 82941), where it was diagnosed that the throttle body had failed and needed to be replaced. The vehicle was repaired. Additionally, the contact stated that the windshield wipers failed to disengage and remained on slow intermittent mode. The dealer reset the windshield wipers setting; however, the failure persisted. The vehicle was not repaired. The manufacturer was notified of the failure and informed the contact that the VIN was not included in a recall. The failure mileage was approximately 90,000.

Downshifting while I was driving happened without warning. Besides the gear switch, I noticed problems with the speedometer, erratic gear shifting, and the transmission stuck in one gear. I could have caused a major accident by the vehicle as I was at moderately high speed in motion when the vehicle began to fail. I did also bang my head on the steering wheel when the truck began to decelerate on its own! Mechanics told me it was a problem with the OOS (Output Speed Shaft Sensor). I could have got in a major accident had I not had a quick reaction to the truck automatically downshifting while at a high rate of speed. There is currently NO recalls for the 2016 F-150 model however, I did research and found that there are issues recalls for this VERY same problem for older F-150 models. This is an incredibly dangerous problem. My truck at this time only has 66,000 miles. Not very many miles on it for a 2016 to have this type of issue. Major research needed to get this resolved asap! People’s lives are at stake with this truck!

I was following behind my sister driving the vehicle. While on the interstate behind a big rig in the fast lane, he was driving in the lane without passing anyone. I thought my sister was tired of following behind the rig and decided to pass him in the right lane. After watching her apply the brakes several times, she moved (to the next only and right) lane and the truck kept accelerating to high speeds 70, 75, 80, 85, 90 and then to 95 miles per hour, all along she is trying to apply the brake and it is not helping but you could see the taillights lighting up. Finally about a mile down the road she was able to get the truck back in control and pulled over into the median. We are all lucky the interstate was not congested at this area at this point of time, especially my sister.

When accelerating to merge on to a major highway, my truck lost power and went into “limp mode”. This caused rapid deceleration and I was nearly rear-ended by a semi-truck with my family in my truck. I had to slow to a stop on the shoulder and shut the engine off and back on to clear the faults and drive away. Error codes: hill start assist not available, hill descent control fault, and the service wrench and “see manual”. I also received the P2112 engine error code for throttle body stuck shut. This entire sequence repeated approximately 15 times before I could get it to the dealer and I was significantly reduced in my ability to accelerate (at all speeds) until it was fixed. This is a major safety issue and needs to be recalled immediately. Throttle bodies should not fail at 60k miles. Ford replaced my throttle body and the issue was corrected.
