The safety recall for my 2012 Ford F-150 that was to fix a sudden downshift on the truck did not work. From what I have read; the root cause for this random downshifting is identified by as this: a defective bulk head connector. When trans fluid leaks past the bulk head sealing rings it can disrupt the transmission's output speed sensor signal. When this happens the ECM automatically downshifts to second or first gear. to fix this issue Ford released a TSB that was comprised of a software update designed to prevent the ECM from automatically downshifting when the loss of signal occurs (I don't know what other conditions have to occur simultaneously). This fix is less labor intensive (thus cheaper) than replacing the actual bulk head connector assembly. Ford has released a revised part number for the bulkhead connector as well. The sudden downshift which has always been prevalent on this truck continues to happen, it-??s a safety concern that is going to cost me a lot of money to fix that they should be fixing instead of programming a software update that is a temporary fix.

The issue that is wrong with this vehicle matches a previous recall that Ford has put out for the same year, make, model. However, this vehicle was excluded from the recall. The recall is 19S07 for the other vehicles. This recall needs to be extended to more than just the 1.2 million vehicles that were recalled. This issue is common in this vehicle, even in ones that were not included in the call. This is a Ford issue, not a customer/owner issue. It caused my vehicle to lose control of the speedometer, it dropped to zero. It caused my vehicle to get stuck in a gear and not be able to move out of it. This causes a safety issue for not only myself but other vehicles around. It can cause car accidents due to the sudden jerking and decrease in speed. I have had this issue diagnosed by a Ford dealer AND independent transmission shop. The issue gives no warning and pops up randomly. People-??s lives are at risk. EXTEND THE RECALL!!!!!

The contact owns a 2012 Ford F-150. The contact stated while driving 55 MPH, the contact attempted to accelerate however, the vehicle failed to respond. The check engine warning light was illuminated. The contact pulled over and turned off and restarted the vehicle. The vehicle drove normally however, the check engine warning light remained illuminated. The vehicle was taken to the dealer where an unknown calibration was performed however, the failure recurred. The manufacturer was contacted and informed the contact that the vehicle was out of warranty. The contact was referred to the NHTSA for assistance. The failure mileage was 139,501.

Our truck suddenly went into "limp-mode, " for no reason. When we turned the truck off and back on, it was fine.

Brake Failure: The brake Vacuum Boost pump is failing which causes a loss of power assist brakes. This is a massive safety issue and can cause serious accidents. Oddly Fors no longer manufactures the Bracket to be able to replace the pump and there is no aftermarket alternative. My Dealer tells me their notes from ford say obtains from aftermarket but I have scoured the internet and nobody makes the bracket. IT's a terrible design and a huge safety issue that should be recalled completely. Ford watts to charge over $900 to fix it but cant even get the parts as described above. Transmission Lead Rail: Recently had the Transmission Lead rail fail whcih casued sudden downshiting at highway speeds and the shift indicator to not illuinate. THis again is a massive safetey issue that Ford issued sevral TSB on but never recalled. This almost got me killed on thehighway a few times. They charged me over $1500 to replace the LEAD rail when again this defcetive design and craftsmenship that is a massive safetey issue and should be fully recalled. Engine Stutter: My truck has almost always stuttered anytime you wne tover hal throtle, There are sveral TSB on this but FORD has not stepped up and taken care o fht eissue via recall. Apprnetly moisture build up in the inercooler and gets sucked into the intake due to poor design. Timing Chain Stretch: I now have Timing chain stretch, this also seems ot be quite common due to poor design. Rear Door Failure: I can no longer open my rear half door due to failure of internal plastic door components. You can research any o fhtese issues and find that htey are very common pronlems in F150 and other Ford vehicles due to their negligence in design and engineering and some are huge safetey issues that FORD has somehow been alloweed to ignore or issue insufficinet TSB instead of Recall.

My 2012 Ford F-150 has 98000 miles on it right now. Right about when it reached 90000 miles on it, it started having this loud rattling sound during startups, coming from the engine compartment. Everywhere I looked, it stated it was a -??timing chain-?? issue. I took it to 2 separate Ford dealerships, each numerous times, and neither would fix the issue, apparently because the issue did happened at the dealership. Note, the truck was still on the warranty at the time. Now, 8000 miles later, the issue has gotten worse. The noise is getting louder and last for almost 3-5 seconds. I don-??t know what to do. I don-??t feel I have to put out of my pocket to fix this problem.

I began to hear timing chain rattle upon cold start up around 100000miles. I had the motor replaced at 122,000miles and both turbos per dealer and extended warranty recommendation. Now after strictly following oil change intervals over the last 28,000miles I am in the same boat. I have horrible chain rattle upon cold engine crank on a new motor.

Vehicle shut off while driving approx 30 mph making a slight right hand turn. Thus losing all throttle, power steering and power brakes. Vehicle error message is low oil pressure but oil level is checked out to be good. Based on online research the culprit is an overheated fuel pump fuse and a very common issue.

After starting the vehicle and putting it into drive, the vehicle would not shift out of 1st gear. RPS revved nearly to red-line and even when I removed my foot from the gas pedal, the revs remained high. Even when underway, the speedometer registered 0 MPH and the odometer was showing only dashes "-------------". After a short time, the wrench symbol appeared on the display and the airbag warning icon was illuminated. I pulled over and turned the truck off and back on and it operated normally. No error codes were stored and my service shop will not work on it since it is not happening all the time. On a different occasion about a week ago, I was driving up a residential street incline and the truck was not shifting from 2nd gear. I pressed the accelerator more and all of sudden the truck shifted extremely rough jerking myself and my passenger unsafely. After this the truck stuck in gear, displayed the wrench symbol and illuminated the air bag warning icon. This looks to be highly related to Ford Safety Recall 19S07 but my truck is not covered by this recall.

In June of 2018 I purchased my 2012 F150 5.0 with 16,250 miles. I now have 40,650. Back in Oct of 2020 I began having issues with the trucks engine sputtering, chugging, etc.. when accelerating in day to day to traffic. The engine would run very rough while I sat on the side of the road or in the middle of traffic waiting for the truck to "work through it" or completely die. I'd wait a few minutes, start it back up and be on my way. I can be sitting at a light, it turns green and I take off and it'll act up or even when I'm traveling down the road a car in front of me slows down to turn and after they turn I press the accelerator and it acts up. It throws no codes but I'm a sitting duck out there when this happens due to the extreme quick loss of power. In most cases of this happening I usually don't have enough momentum to get out of the way of traffic causing unsafe conditions for all. Its very random and unpredictable evident by it occurring several times in a week or not at all for several weeks. As soon as this issue began I had the throttle body replaced by my mechanic but it still continued. My mechanic even kept my truck to drive around at different times during two sperate weeks to "re-enact" the issue, but it never happened. Within a day or two of getting it back from him it would happen again. I've been to Ford and if your vehicle doesn't throw a code they don't have time for you, "but if there's anything else they can do for you just let them know". this is a hassle, unsafe situation that I've been dealing with for several months now with no one able to give me any answers to fix this. Yes, I've seen and heard the list of everything it could possible be from bumper to bumper. I need a resolution because I've extinguished all other avenues.

The contact owns a 2012 Ford F-150 the contact stated while driving approximately 60 to 80 mph, the vehicle downshifted to first gear. The contact stated that the failure occurred on numerous occasions. The check engine warning light illuminated and the instrument panel darkened during the failure. The contact moved onto the road shoulder, shifted into neutral, turned off the vehicle and opened the door to reset the computer. The contact then unlocked the door, restarted the vehicle and the vehicle resumed normal operation. The contact performed a self diagnostic test on the vehicle and retrieved dtc codes: P0722, P1500, T0720 which confirmed a loss of communication between the speed sensor within the transmission. The vehicle was taken to don rich Ford company Inc (221 E montgomery St, villa rica, ga 30180, (770) 459-5132) to be diagnosed. The dealer declined to re-flash the computer as requested by the contact. The manufacturer was contacted. The vehicle was not repaired. The approximate failure mileage was 139,000.

I was driving down a hill on a main street with my kids when my F150 2012 suddenly shifted into first gear. I almost lost control into on coming traffic and the vehicles behind me had to slam on their brakes to avoid rear ending me also. I had to put the truck in park before I was able to get it to shift out of first gear and make my way to my house. I told my wife what happened and she mentioned that something similar happened to her. I immediately called the local Ford dealership and they said there was a recall to solve the issue and could fix it in approximately six days. After picking the truck up the same incident happened on the drive home. It dropped into first gear from 3rd or 4th and almost locked up the tires on a busy road. I was extremely upset with Ford for returning an unsafe vehicle stating they had fixed the problem without testing it to be sure and putting my family in danger. I called them back and they said that was the only fix on the recall. I hope Ford is not getting off that easy by doing a software fix when obviously the problem is bigger. They must be held to a safe standard and accountable to ensure the safety of not only their customers but other people on the roads. The fact that the mechanics are now telling me that this is a common problem and they know the fix but want us the consumers to pay to fix their wide spread issues is frustrating and scary imaging how many people wont be able to or want to fix the issue and sell the vehicles passing the safety hazard on.

The 2011-2013 Ford F-150 eco boost is known to have timing chain stretch issues causing possible total engine failure. 25 months ago we spent $3,700 having cams and phasers and all chains repaired by a Ford certified dealer with Ford motor craft parts. Less than 1 month following the warranty of the work the secondary timing chain has failed leaving the vehicle useable while my wife was traveling down a gravel road and we are looking at another $3,700 repair plus a tow and inconvenience for a known and repeated problem and Ford will not stand behind these issues.

I was backing out of my driveway when as soon as I got out my truck suddenly locked up and then the engine light came on with the service light and also the wrench light and as I was driving my speedometer wouldn't go past 0 but would still accelerate. This was happening while driving down the road going about 15mph.

My truck was 10,000 miles out of its extended warranty when on cold start up the engine would rattle on startup. I took it to the Ford dealer in my area and was told the timing chain and cam phasers would need to be replaced. The dealer had my truck for 2 months. With parts on back order. With the transmission service I had done the total bill was $3,085.51. The truck was regularly serviced every 5,000 miles by a Ford dealer. The cause of the problem was not lack of maintenance it was an engineering flaw from the manufacturer. Due to this I feel like I shouldn't be financially responsible.
