Well known 6R80 Transmission Molded Lead Frame defective, causing unexpected and dangerous downshift/loss of power, instrument gauges malfunction and both wrench light and engine light come on. Ford somehow avoided recall to save millions, instead issuing Customer Satisfaction Program 19N01, however replacement part is in short supply and dealerships weren't taking appointments then due to Covid pandemic. Following up recently with Ford dealer since symptoms have worsened, apparently program is now expired and they won't fix. We were nearly rear-ended twice attempting to merge onto freeway, so took it to a reputable local former Ford tech, but he can't obtain the part, which is back ordered everywhere, yet apparently Ford has. Putting everyone on notice and hoping it doesn't take a serious accident/avoidable lawsuit for Ford to do the right thing. Pls advise accordingly. Thank You. Desperate in NV...

The vehicle was being driven with the cruise control set. Upon approaching an intersection on a four lane divided roadway I tapped the brakes to deactivate the cruise control. When pressure was applied to the brake pedal the cruise control did not disengage but the vehicle accelerated instead. I released pressure to the brake pedal and the vehicle continued at the cruise control set speed. I again applied pressure to the brake pedal and the vehicle again accelerated. To avoid striking stopped traffic I moved into the right turn lane with the vehicle continuing to accelerate as I attempted to brake the vehicle. Upon entering the intersection my vehicle struck another pickup truck broadside. I believe speed at the point of impact was 60 plus miles per hour. My vehicle then continued on and struck two utility poles. Both vehicles were damaged beyond repair. There appears to be a problem with the speed control system as it would not disengage but caused the vehicle to accelerate. Googling the same problem with other Ford F-150's I found several reports of the exact problem. I ordered the vehicle new and it was maintained by the Ford dealership. There were no known problems. Mileage is 31,900. At this time the vehicle has not been inspected for a cause but is available for inspection. The vehicle is in the towing company lot. This accident could have very easily resulted in fatalities. This accident should have never happened!!!

I was driving with the cruise control engaged set at 60 mph. Approached an intersection with traffic light with traffic stopped in both westbound lanes. Tapped the brake to deactivate the cruise control. The cruise control did not turn off but instead tapping the brake caused the truck to accelerate. Released the brake pressure and reapplied brake pressure. This action again caused the truck to accelerate. To avoid hitting stopped traffic I moved to the right hand turn lane which was free of traffic. The truck continued to accelerate as I applied brake pressure. As my truck entered the intersection a collision occurred with a northbound vehicle. The collision severely damaged my vehicle and the struck vehicle with injuries to myself and the other driver. Crash speed had to be over 60 mph. This was all captured by a traffic camera. My F-150 had 31,900 on the odometer. It has been dealership maintained since new and has no known defects other than this incident. No lights, no warnings. The truck has not been Inspected since the incident. The truck has heavy damage. This incident could have easily caused the deaths of myself and the other driver. Searches online have turned up the same complaints from other F-150 owners. I have photos on my email but can not get them loaded to this form. You need to see them!

11 May 2022: Turned right into four lane traffic and accelerated. Truck refused to shift out of first gear. I had to make the first turn I could to get out of traffic. Turned truck off and re-started engine. Problem was resolved. Wednesday 18 May: Driving west on Hwy 7 at about 65 MPH. Truck lurched slightly and all speed/distance indicators on dash went blank. A single wrench was displayed. Speedometer dropped to Zero MPH.Truck seemed to drive just fine so I limped to a gas station a mile away. There I shut the truck off again and restarted the engine. Engine ran fine but no odometer readings still. Being 15 miles from the next town I decided to continue to drive slow. Shifting was normal and truck ran fine just no speedometer. I Drove straight to the first auto parts store (Advanced Auto) who read the fault code for me. It was something like Failed Speed Transmitter. Driving home that evening the truck seemed fine again. Normal start all displays working no wrench showing. I was driving 55 slowed to 45 for a speed zone. Then coasted to a stop for the red light. When the light turned green I drove. Instead of shifting up the truck stayed in first and even when I lifted my foot from the gas pedal the truck continued to accelerate to over 40 MPH. I Had to apply the brake to stop the acceleration. This was on HWY 7 four lanes of traffic. I had to get pulled off the road and re-start the truck again. The truck is now parked. All quotes I have to 'fix' this are beyond my ability to pay. And no-one (Even the Ford Dealer) will warranty any results other than a new sender unit and not any 'un-forseen' issues later.

Vehicle speedometer stopped working, the total mileage indicator read all dashes -€œ- - - - - --€œ and the transmission was shifting to the wrong gear. For example from a stop the truck would immediately be in fifth gear. The yellow wrench indicator came on briefly and then went away. I turned the truck off then on again and the problem went away and I made it home. Today I took the car to get the safety recall completed, and on my way home the car speedometer stopped working again and I was not able to accelerate while I was making a left turn. This left me stranded in the middle of the intersection and I had to restart the car and the problem went away. I asked the dealer if they would look into the lead frame extended warranty and they would not honor the coverage because I am at 155,000 miles and the coverage ends at 150,000 miles and because it is a 10 year coverage but my car was manufactured 10 years and 3 months ago. The recall did not fix my issue and the vehicle is not safe to drive. The issue is however intermittent and I am a college student who must commute 1hour away to attend the university. I don-€™t feel safe driving the vehicle, there was one point when the car down shifted rapidly and caused my car to jerk to a stop. I was only going 15 miles per hour so it was not too dangerous. Please help. The recall software update is all they were willing to help me with. Although the problem still persists.

Speed sensor stops communicating causing the truck to shift in first gear. This has caused the back wheels to lock up and could cause serious wreck. I need to have this fixed ASAP at no charge. This is a $40,000 truck and should not be having these dangerous issues. I hope this can be taken care of without contacting the news and my attorney

My transmission is downshifting on its on when driving home without changing gears. I have to shut it off and wait before I can drive it again. I was in the flow of traffic when this happens and it is very scary. And it continues so I'm unable to drive it because it's to dangerous.

I I took this vehicle to Ford of dalton, Georgia because there is a safety recall on the PCM and transmision that will suddenly downshift into 1st gear while going down the road. Customer service manager stated that it would cost me $140 dollars to diagnose the problem, and if the problem was the molded lead frame in the transmission that communicates with the output shaft sensor, that it would not be covered by the recall or warranty. This contradicts what the recall states. I shouldnt be charged $140 dollars for them to diagnose a recall..this is on a 2011 Ford F-150

After tapping the floor accelerator the engine went to full throttle and stayed there. Even after putting the vehicle in park the engine remained at 7000 RPM. Outside temp was -2F. Vehicle had been idling for 7 minutes prior to the incident. The event occurred while pulling into park at 10 mph. Almost hit a parked car and building but was able to brake and put the vehicle in park. After running at full throttle in park for at least 30 seconds the engine shut down. Also, the driver's side windshield wash spray stopped working a few days earlier.

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."

2011 Ford F150 starter problems. I've replaced starter on this vehicle multiple times and still have issue's. I turn ignition and all that happens is a screeching noise. After a couple tries it starts. Second issue is speed control issues. I was driving on city streets and all of a sudden my speedometer stopped working. My truck would not shift and had to manually shift gears.

Truck locked up on me on the highway doing 70+ mph & caused me to spin out & wreck. It's a recall for that issue that Ford will not fix for me because of mileage. Terrible customer service & endangered my life & others that day for a issue that they're responsible for.

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.
