Ford issued a recall for the Lead frame. Recall ID 19so7 & 16s19. My truck has experienced the issues associated with this recall. Last night it was more severe. The truck shifted from 5th to 1st gear unexpectedly. I have already tried to remedy this with ford. I made the appointment on their website to have this fixed in the beginning of spring this year. I was told when i brought it in that it wasnt covered anymore because its over 10 years old and over 150,000 miles. This should not matter when we are talking about a serious safety issue. The truck is in good shape and this is the only issue I've had. Now, im afraid to drive it at all. It never downshifted like thos before. The most it did was, all of a sudden, the "wrench symbol" would appear and my speedometer would stop working and it wouldnt shift properly. I'd pull over and it wouldnt go into first. If I restarted the truck it would reset and work again. But this would happen from time to time. Then yesterday it did exactly what the recall states it would do. Ford denied it was a recall to me and said it was a "customer satisfaction program" instead. But clearly its a recall and a huge safety issue.
The contact owns a 2011 Ford F-150. The contact stated that while driving at 60 MPH, the vehicle experienced a slight loss of motive power, and the transmission failed to shift in synchronization with the engine. The check engine warning light and the service vehicle soon warning light illuminated. A diagnostic scanner retrieved transmission code 6R80. A dealer was contacted; however, the vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The contact associated the failure with NHTSA Campaign Number: 19V075000 (Power Train). The failure mileage was 225,000.
The contact owns a 2011 Ford F-150. The contact stated that while driving at approximately 55 MPH, the transmission erroneously downshifted, causing the vehicle to abruptly reduce speed. The contact indicated during the incident that the transmission shifter switched from Drive (D) to the first gear independently. The contact was informed that the VIN was not included in NHTSA Campaign Number: 19V075000 (Power Train), which the contact associated with the failure. The failure mileage was 165,000.
My truck will just abruptly downshift no matter how fast im going and it's quite concerning
I was parking the vehicle and turned off the engine when the speakers gave out a loud noise. I turned the truck on to see if it would continue but there was no music and smoke began coming out around the radio. I moved the truck away from building and retrieved the fire extinguisher from the back seat. I noticed the "door ajar" warning was on even when the doors were closed. The smoke subsided and I did some quick research online. I was able to find a lot of information about the wire harness between the driver's side rear door and door frame being damaged, producing these symptoms. I disconnected the battery and removed the sheath from the wiring harness. Three wires were severed and several were frayed. (see attached photos) I contacted the local Ford dealership and they explained how it could be replaced at the wire connector in the door frame. Most trucks have a connector in the door frame, this truck does not so the Ford tech offered to solder the wires together. I am experienced in wiring and auto mechanics so I completed the repairs myself as he described.
I bought this truck used about one year ago. Since then I have not had much time to use it. In the last three months I have had some time to drive it. Three times in those months this issue has occurred. Luckily they all occurred on my property and no damage happened except to the truck. First time it happened an exterior mirror was knocked off, a running board was bent, scratches and dings to the to the paint, and a tailight was damaged. This all happened in reverse due to a gate opening I was going through. The motor all of a sudden had a massive spike in RPMs and a violent lunge and slide of the vehicle. I learned later that it was due to a flawed part in the transmission called a molded lead frame. Transmission is Fords 6R80 6-speed automatic. Last time it happened was on 09/16/2026. It has not been inspected by any entity because apparenty I live too far in the "boonies" for anyone to come this far but the vehicle is available for inspection upon request.

While driving at highway speed my f150 justdown shited to third gear after stoopping it wouldn't take off.Ihad to shut engine off to get back to first gear .
Made a complete stop and vehicle accelerated at a high rate of speed and could not stop.
I am having a lead frame issue. At various speeds, the vehicle will just down shift, locking the tires and causing a hazard for other drivers which could be a very dangerous situation. I was impacted from the rear due to this occurrence. It causes extreme jerkiness when doing this which is also injurious to my back and neck and shoulders.
What component or system failed or malfunctioned, and is it available for inspection upon request? “We lost power while driving, along with a weird downshift today, 5/16/2026. This is happen one other time, however not as bad.” How was your safety or the safety of others put at risk? “It could have been way worse, lucky there was a left turn lane that avoided us being rear ended by the vehicle behind us.” Has the problem been reproduced or confirmed by a dealer or independent service center? “Not for this time, but it will be going in first thing Monday. We did have it looked at back in April when it did a weird downshift while driving, but they couldn’t find an issue then.” Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? “No, but it will be after this incident.” Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? “No warning lights, just loss of power and an intense downshift. The first time the downshift thing happened was back in April, but nothing more. We had a mechanic look at it, but nothing happened for him then.”
I've sent earlier not sure if it went through transmission dropingvout of gear at any time putting my. Life in danger, and family, hope I don't end up needing a lawyer if a major fatality happens
My vehicle has abrupt unintended downshifts straight down to first gear at fast speeds, which is causing rear-wheel lockage near heart attack and near-loss of control spinout. The sudden downshifting causes a loud violent high extreme RPM engine over rev. sounding as if it is about to blow up or an internal explosion. This is occurring at highway speeds up to 70 mph. At these speeds, is an immediate risk to me and others! Causing a fatal high-speed rollover or a multi-vehicle collision due to this malfunction! This was a recall 19S07 for my year of truck but my Vin was somehow was not on the list which I guess makes me not qualified unless I get into a crash and then have a lawsuit.
I contacted ford about my molded lead frame because my truck has a issue with the transmission and they denied my coverage to repair the problem and it’s is expired so the won’t fix the issue.
When taking off the vehicle will shift into 5th gear trying to take off then hard shift down to 1st then up to 3rd and violently jerk forward. When pressing the brake pedal at a stop light it will jerk forward. When going uphill the vehicle will struggle in 5th gear and then downshift to 4th and loose power and gain power and doesn’t move unless at high rpm’s ( 3000-4000). When on the interstate it will start to move and then loose power then gain power over and over. It will be moving fine then but when taking off it will be stuck in 1st gear and refusing to shift which will then cause dangerous situations with going through intersections
I am writing to formally report a dangerous safety failure on my Ford F-150 that persists after having the recommended recall service (19S07) performed. While traveling at highway speeds, my vehicle experienced an uncommanded downshift from 6th gear to 1st gear. This caused an immediate and violent deceleration, nearly resulting in a high-speed rear-end collision. This exact failure is the core safety issue addressed by Ford's powertrain control module (PCM) recall, yet the "fix" provided has failed to protect the vehicle from this life-threatening defect. I took the truck to Bolivar Ford in Tennessee for resolution. However, the dealership refused to perform any further repairs under the recall. They stated that because of my current mileage, the recall coverage has "expired." Furthermore, they diagnosed the issue as a faulty lead frame sensor—the very component linked to these downshift events—and quoted me $2,500 just to begin the repair process. A safety recall is intended to permanently rectify a defect that poses a risk to life and limb. The fact that the vehicle is still performing this dangerous maneuver after the recall was "accomplished" suggests the initial remedy was insufficient or the underlying hardware remains defective. I am requesting that Ford Motor Company intervene to ensure this vehicle is repaired at no cost to me. Given the severity of the safety risk, I do not believe mileage should disqualify a customer from having a documented, lethal defect corrected—especially when the first repair attempt failed. I look forward to your immediate response regarding how Ford intends to resolve this safety matter.
I was driving 70mph and my truck went from sixth gear down to first gear. I almost wrecked. The odometer went to zero and a little wrench showed up on the dash. I had to pull over and turn off the vehicle.
NHTSA’s Office of Defects Investigation opened these reviews into vehicles including this one.
The Office of Defects Investigation (ODI) opened an investigation based on consumer allegations of transmissions unexpectedly downshifting to a lower gear without input from the driver on model year (MY) 2011-2013 Ford F-150, Expedition and Navigator vehicles. ODI has received 455 unique reports related to the alleged problem that were not covered under a previous recall for this issue (16V-248).Expedition and Navigator complaint rates are lower than F-150 complaints. Of those 455 reports, 34.7% claimed that the rear wheels locked up when the transmission downshifted. There were 4 accident claims with no injuries. There are many instances where drivers report leaving their lane or the road because of this issue.In response to ODI's Information Request (IR) letter, Ford Motor Company (Ford) responded with 783 unique reports related to the alleged problem. There were 6 accident claims with 3 injuries. Ford also submitted 1206 warranty claims related to transmission downshifting failures. The failure can occur at any time, but typically at higher speed, and include symptoms such as sudden transmission downshifting, loss of speedometer, erratic shifting of transmission, and transmission stuck in one gear. The failures typically occur without warning and may result in the rear wheels momentarily locking up. The driver often had to fully stop the vehicle and restart it to get the vehicle to shift properly.On February 2nd, 2019 Ford notified ODI that it would conduct a safety recall (19V-075) to remedy transmission downshifting failures on all 2011-2013 F-150 vehicles. Ford will also offer extended warranties to 2011-2013 Expedition and Navigator vehicles with the same issue. Per Ford, some vehicles may experience an intermittent loss of Transmission Output Speed Sensor (OSS) signal to the Powertrain Control Module (PCM), potentially resulting in a temporary unintended downshift into first gear. Ford will reprogram the PCM with software that will prevent an unintended downshift into first gear and illuminate the Malfunction Indicator Light in the event of an intermittent OSS signal loss.The recall action initiated by the manufacturer appears to address the safety risks of concern to ODI.Accordingly, the investigation is closed.The ODI reports cited above can be reviewed at www-odi.nhtsa.dot.gov/owners/SearchNHTSAID under the identification (ODI) numbers found in the attached list.
On February 15, 2016, Ford Motor Company initiated Customer Satisfaction Program 15N05 to extend warranty coverage for the electric vacuum pump in certain model year (MY) 2011 through 2012 Ford F-150 pickup trucks equipped with 3.5L GTDI engines.The program extends coverage for up to 10 years of service or 150,000 miles from the warranty start date of the vehicle, all vehicles are eligible for the program through July 30, 2016 regardless of mileage.Ford's program covers all repairs related to electric vacuum pump (EVP) malfunctions including excessive noise, vibration, or change in brake pedal feel while applying the brakes at cold start. Ford states that the engine intake manifold is the primary source of vacuum for the brake booster and is fully compliant to motor vehicle safety standards without the supplemental vacuum supplied by the EVP.The company also contends that failure modes related to the EVP are progressive and provide warning to operators by way of noise and vibration before an operator to experience any temporary change in brake pedal feel.ODI's analysis of warranty data found that the majority of claims involved consumer concerns with EVP noise or vibration from the left front fender area when the vehicle is first started. Continued operation in this mode with pump motor noise will eventually result in the EVP seizing or becoming non-functional.Component failure analysis indicated that Ford and its supplier, Continental, identified a pump crank drive corrosion condition due to moisture entry through the vacuum intake.Corrosion damage to EVP internal components may eventually result in a blown fuse in the power distribution box and total loss of EVP function.Analysis of consumer complaints, field reports, and warranty data related to EVP failures found thatincidents predominantly occurred in driveways and parking lots in the periods immediately after cold engine starts.Many consumers operated their vehicle for some period of time with a blown EVP fuse without realizing that the pump had failed or that the vehicle had a brake system malfunction.Consumers who did experience braking performance issues reporteda temporary hard brake pedal condition at start-up followed by more consistent normal pedal feel after few seconds.On June 22, 2015, Ford developed a remedy procedure and issued TSB 15-0105 instructing dealers to replace the vacuum pump and install a new vacuum pump harness kit. In addition to reviewing test data submitted by Ford, ODI assessed safety risks associated with the alleged defect under various operating conditions, including: 1) baseline system performance with full engine and EVP vacuum available using exemplar parts, 2) disabled EVP and booster vacuum regulated to simulate worst case conditions for engine intake manifold vacuum supply to the brake booster (approximately 300 mbar); and 3) all source vacuum to the brake booster removed and Optimized Hydraulic Braking (OHB) mode active to represent complete loss of brake booster function (note: this condition is a more severe brake boost system failure mode than the alleged defect).ODI also analyzed all complaints and warranty claims to identify incidents alleging brake system performance concerns related to EVP failures.These analyses identified no brake performance issues or resulting changes in stopping distances either on highway or city traffic conditions.Two complaints alleging EVP malfunctions caused or contributed to rear-end collisions during attempted decelerations from road speeds are not believed to be related to the alleged defect.The EVP provides supplemental vacuum during initial start-up and idle
On June 22, 2015, the Office of Defects Investigations (ODI) opened Preliminary Evaluation PE15-026 to investigate incidents of increased brake pedal effort at cold start and extended stopping distance while driving in traffic, resulting from failures of the electric brake vacuum assist pump in model year (MY) 2011-2012 Ford F-150 pickup trucks equipped with 3.5L GTDI engines. In response to ODI's Information Request (IR) for PE15-026, Ford provided ODI with 396 complaints and field reports relating to incidents of increased brake pedal effort or malfunctions in the electric vacuum pump (EVP). ODI's analysis of the data provided by Ford identified 7 crashes and 1,851 warranty claims related to either a hard brake pedal condition or reduced brake effectiveness. Additionally, ODI identified one report in its database alleging an injury to an occupant of a vehicle struck in the rear by a subject F-150 vehicle with a failed EVP as documented in the police accident report referencing a dealer assessment of the pump.According to Ford, the subject vehicles utilize a traditional brake vacuum booster to provide power assist for braking and the EVP is intended to operate to maintain consistent brake pedal feel. The engine intake manifold is the primary source of vacuum for the booster and is fully compliant to motor vehicle safety standards without the EVP. Ford described the conditions related to a change in brake pedal feel as limited and temporary and provided component failure analysis showing evidence of water entry into the EVP which caused internal pump corrosion. Ford indicated that the EVP failure mode is progressive and provides warning to operators by way of noise and vibration before an operator is likely to experience any temporary change in brake pedal feel. Damage to the EVP motor bearing may eventually result in a blown EVP fuse and total loss of EVP function. Ford provided test data showing the brake pedal forces and pedal travel curves over time for 0.3g decelerations to a stop from 80kph (50mph) for: 1) normal system (full engine and EVP vacuum available); 2) Ford's approximation of worst case booster performance with EVP failure (EVP disabled and booster vacuum regulated to 300mbar to simulate cold start, all accessory loads on, and starting at 0 vacuum); and 3) with all source vacuum to the brake booster removed and Hydraulic Boost Compensation (HBC) active to represent complete loss of brake booster function. The Ford tests showed that the brake pedal forces required for achieving the 0.3g decelerations were relatively low for the normal condition, 35-40 N (8-9 lbf), increased by approximately 2-3 times normal when the EVP is disabled, 75-115 N (17-26 lbf), and increased by about 5-6 times normal for the complete brake booster failure condition, 205-215 N (46-48 lbf). This Preliminary Evaluation has been upgraded to Engineering Analysis (EA15-006) to test for EVP malfunctions under other vehicle operating conditions (e.g., low-speed driveway braking after cold-start with failed EVP), potential human factors contributions and to further assess the scope, frequency, and safety-related consequences of the alleged defect.The VOQs associated with the opening of this investigation are:10565994, 10575987, 10598351, 10604687, 10605701, 10607811, 10610491, 10615536, 10617828, 10619545, 10643075, 10650578, 10662151, 10664415, 10666988, 10668069, 10678844, 10695537, 10700874, 10706217, 10706271, 10712465, 10723033, 10723792, 10726960, 10730549, 10730721, 10730735, 10730837, 10730909, 10731008, 10731135, 10731157, 10731165, 10731395, 10731758, 10732609, 10732878, 10733375, 10733804, 10734558, 10734613, 10743859, 10744214, 10
On May 22, 2013, the Office of Defects Investigation (ODI) opened PE13-018 to investigate 95 complaints alleging incidents of reduced engine power during hard accelerations in model year (MY) 2011 through 2013 Ford F-150 trucks.ODI was aware of three technical service bulletins (TSBs) issued by Ford for a condition that was related to moisture accumulation in the Charge Air Cooler (CAC) for the turbochargers.A Preliminary Evaluation was opened to gather information to assess whether the subject vehicles contain a safety related defect.The subject vehicles are powered by Ford?s 3.5L EcoBoost engine which uses twin turbochargers to obtain a balance of fuel economy and engine power based on the driver?s demand.When the driver requests more power from the engine, as in accelerating to pass, merge, ascend hills or haul a load the two turbochargers will spin up compressing the air which is then used to increase the power created by the combustion in the engine.The compressed air, which gains heat by the compression process, is passed through a Charge Air Cooler (CAC) which is designed to lower the temperature of the air in order to make the combustion process even more efficient (Figures 1 and 2).In response to ODI?s Information Request letter, Ford indicated that a misfire condition could occur after steady-speed operation under significantly humid and rainy conditions.Ford?s analysis found that under those conditions, condensation could form and accumulate on the inside of the CAC tubes which could then be ingested into the engine during particularly hard acceleration near wide-open throttle.An engine misfire of up to three cylinders could occur if the amount of condensed water released from the CAC exceeded the engine?s operating threshold for water ingestion.Ford noted that due to regulations set by the EPA, the powertrain software would disable up to two of the misfiring cylinders for no more than 30 seconds and until the driver tips out the throttle in order to protect the catalytic converter from damage. Ford?s testing of this condition on the subject vehicles showed that a vehicle experiencing such a condition would continue to maintain its speed as well as accelerate, albeit at a lower rate than expected by the driver.Similar results were obtained in testing done by NHTSA?s Vehicle Research and Testing Center in East Liberty, Ohio (Figure 6).In an ongoing process to address the problem Ford issued a series of TSBs where a deflector shield was installed onto the CAC (Figures 3, 4 and 5).In January 2014 Ford indicated that its data shows that the TSBs have been effective in resolving the problem, that for the MY 2013 vehicles their remedy is 100% effective and the latest TSBs for MY 2011 ? 2012 are 95% effective.The 525 complaints to ODI and the total 4,120 unique VIN complaints listed in the Failure Report are incidents of alleged reduced power or driveability symptoms and not all are necessarily related to the condition created by water ingestion.Reduced power conditions can occur for a variety of reasons including faults with ignition coils, spark plugs, a catalytic converter, the throttle body, turbocharger, fuel pump/filter, powertrain control module (hardware or software) or transmission shifting problems.Ford also noted that in a large number of warranty claims on the subject vehicles, the CAC was replaced or a TSB procedure was performed when the symptoms exhibited were inconsistent with a CAC water ingestion related issue.Given these circumstances, further use of the agency resources in this matter does not appear to be warranted.Accordingly, this investigation is closed.The closing of
