The lead frame on my truck was experiencing issues. The truck would intermittently randomly downshift at high speeds or get stuck in one gear. I was going 65+ mph on the freeway and and my truck shifted to second gear with no warning causing me to swerve and slam on the brakes. Other times my truck did it on surface streets. There were no warning lights or anything to let me know it would happen. After it downshifted, the wrench popped up on the dash, my speedometer went to 0, and my odometer read blank. Forcing me to pull over, restart the truck, in order to get it out of limp mode to be able to make it home. I took my truck to Ford of Valencia California where they inspected the truck and confirmed it was the lead frame. The issue was that at the time the part was on an 8 month back order so my only option was to replace the entire Valve body instead of only the lead frame. My truck was no longer under the recall and I was forced to pay for this out of pocket less than a month of purchasing the truck from a used dealership. My truck was only inspected by Ford of Valencia and no other agencies. Since this truck was my only form on transportation, I could not wait the 8 months for the lead frame to come in and had to pay out of pocket for the new valve body.

Ford 150 2011 has had acceleration issues for the last 2 years. I heard there was a recall on this model of truck with the Eco boost but mine was not on the list but I am now having issues and mechanics are having a difficult time figuring out what has been happening. Code light doesn't specify a problem.

I was driving on the highway at 65 mph and the truck downshifted on it's own from 6th gear to 3rd gear causing the truck to loose power. This has happened twice while driving on the highway and the transmission recall has been updated prior to this.

This vehicle has an automatic transmission. It will not shift out of first gear in the drive setting and the speedometer registers 0 mph when moving in first gear. If I shift to the manual setting, I can shift up. I did not notice if the speedometer registered my speed at that point.

Truck transmission shifted into 1st dear from 4th while driving on a large 4-lane road in the middle of traffic while i was going approx 35 mph. When the downshift happened the tired locked up and the rear end slid sideways. I was able to regain control; however, as I stepped on the accellerator, the truck bogged down for a few seconds before reving to high RPMs and shifting roughly and then went into a mode that only allowed the truck to move between 3rd and 5th gears.

Driving down the expressway yesterday doing approximately 72 miles per hour and the vehicle does a HARD SLAM down to first gear and picks right back up to 6th. Now my concern is not only for the lead frame issue, but my transmission is being damaged every time this continues to happen. Since Ford was not able to even LOOK at my car until June 2023 (Its currently APril 28, 2023), I elected to take to a reputable 3rd party repair shop. At which I was told that the parts on are order and on an "undetermined time" for receiving and Im stuck driving my vehicle with these issues, that ford is aware of, that are becoming a bigger safety issue each time I drive it. Disappointing to say the least. Ford cant build quality trucks. They dont own up to their known safety issues. They cant even schedule to see them in a reasonable timeframe. They dont have adequate parts available. And us consumers are stuck footing the bill and inconvenience. Do better Ford. We are all disappointed.

Driving down the expressway, doing around 70 mph and the vehicle randomly jumps to first gear and brings the vehicle to a near halt in less than one second. It happened during rainy conditions and luckily there were no vehicles nearby or I may have struck one of them. At least once per day the vehicle does this at some capacity. No service lights or check engine lights are present.

My truck has been shifting hard..or taking a very long time to shift into gear. When I put the truck into reverse it doesn't indicate/light up the R-reverse light on dashboard which is dangerous not knowing what gear the truck is actually in..after quite some time it will slam or thud hard into reverse but still doesn't illuminate on the dash...then when switching into drive it slams very hard into gear. My acceleration has also been acting up and does not accelerate normal anymore. It's very sluggish and slow to get going which is very dangerous sometimes when entering a highway. I've also been going 40-50 mph and suddenly I lose power and my truck slows down and I have no control over it..hitting the gas only revs engine but does nothing. My reverse lights don't work sometimes either and my rear window has also quit working. I have contacted the locao ford dealer about these issues and the person was not only rude but was without doubt trying to rush me off the phone and told me they were booked up for many weeks and it'd be awhile before I could get the truck looked at...I bought thus truck in November 2019 and had taken it in for a recall that they had to do a quick reprogramming...come to find out there was also at the time a safety recall which "expired'" at 10 years or 150000 miles which is IMO total nonsense and unprofessional of Ford to not make this a real recall that they are required to fix knowing the many issues thousands of vehicles are having due to there negligence when they were built. It's not right to have there customers pay thousands out of there pockets to replace parts that are known to quit working properly and cause many safety issues for people driving the faulty vehicles. We are already paying monthly payments and the only thing the expired safety compliance/ not actual recall is doing for Ford is making them lose loyal customers. I truly worry about the unsafe occurrences that may happen with my child in my truck now and it's not right

I am getting a P0299 code truck and according to research, this is something to do with the Turbo. It is causing my truck to lose power while driving. I have had it parked since then.

While driving, the transmission will randomly down shift into 1st gear and the speedometer will die. The truck flashes a -€œwrench-€ icon. There is no pattern, the issue is intermittent. When the speedometer dies, the transmission will only shift in -€œmanual-€ mode, but will not shift above 3rd gear. The check engine light illuminates and throws codes P0720 and P0722. This indicates an output speed shaft sensor failure. Ford released a Customer Satisfaction Program 19N01 for this issue and offers full repairs. However the repairs were only valid if the truck was less than 10 years old or less than 150,000. My truck is now 11 years old (the issue first was present in May 2022) but I only have 73,000 miles. Ford is unwilling to help because I am outside the warranty by a few months. This is a definite safety concern because I-€™ve been driving on the freeway at 75 MPH in 6th gear only for the transmission to downshift to 1st gear, which causes a violent skid and potential rollover and accident. I live in a severe wintery area, and this issue makes the truck undriveable in the snow and ice. I would like for Ford to run a diagnostic scan, and replace the required components based off their previous CSP. Or, consider this a safety recall and allow me to trade my truck in with no penalties.

The contact owns a 2011 Ford F-150. The contact stated that while driving 10 MPH, the speedometer failed to properly show the speed after exceeding 10 MPH. The contact stated that the transmission failed to shift properly. Additionally, the vehicle was slow to accelerate. There were no warning lights illuminated. The vehicle was taken to the local dealer where it was diagnosed the molded lead frame needed to be replaced. The vehicle was not repaired. The contact stated the failure was related to NHTSA Campaign Number: 19V075000 (Power Train). The manufacturer was contacted and referred her to the NHTSA Hotline. The approximate failure mileage was 75,000.

My vehicle is experiencing the same issues that were identified under recall 16V-248 with the exact same year, make and model vehicle. Several times, while driving at high speeds, the vehicle will display a wrench logo (MIL) and the vehicle will either downshift to 1st gear or completely lose all power to the pedal. After turning the ignition off and back on, for a period of time the vehicle will only move in 1st gear, will not downshift and the speedometer will not move. The check engine light will illuminate for a period of a few days and will without reason turn back off until the downshifting happens again.
