Cylinder 2 had a stored code for misfire and oil and coolant mixture leaking from block. With the F150 raised up on the lift I removed the lower splash shields and continued inspection. Oil was found predominantly on passenger side with a mixture of oil and coolant leaking out drivers side. Using my lab scope I was able to locate the damage in the block. A large crack split down in a Y pattern. This split is located on cylinder #2 location. I would say #2 connecting rod has impacted block due to internal failure.

The problem with this vehicle is the body control module has gone out. It controls everything from the safety functions to back up cameras and engine function and starting. My truck first, lost its back up camera within the first year of purchase, then the driver side, turn signals, stopped working, the battery drains overnight, and the latest issue is that the truck will turn off while driving down the road. Three months ago, the engine cut off and all systems locked up while I was driving 45 mph in town. There are no issues with any other system in the truck. Mechanics have tested everything and state. It is only the body control module. I am unable to purchase a body control module from Ford and my mechanic, the Ford mechanics, the Ford distributor for this region, nor Carmax, where I bought the car can get the part because Ford says that all of their shelf held parts for this vehicle type are defective. They state is a known issue and there is no date for resolution at all. The date on the shelf hold is zero month zero day zero year meaning no date. The body control module in this series of Ford F1 50s is a -??known issue-?? to Ford. Due to their semi conductor manufacturer contract that has lapsed for this older technology, they state that the 4000 vehicle-??s that currently require this part are not they-??re greatest concern. They stated that there is an indefinite -??shelf hold-?? on this part due to their only being less than 50 of them available for anyone to purchase. Those parts that are being held are also suspect of defect. Since I have only owned this vehicle for two years and it is under the extended warranty, I purchased with it having only 19,000 miles on it that I have put on it, it seems that they should at least allow me to buy one of the shelf, held pieces to replace mine. Please help the 4000 of us. Please encourage them to do what-??s right for all of us. I still owe $17k on a non-running vehicle Carmax or Ford wont buy back.

3.5L ecoboost timing chain failure at only 58,000 miles (code P0016 possible turbo problems TBD Front suspension springs are broken. All of these are common threads on many forums. Ford should be held accountable even though mine is 10 years old, the mileage is the issue. FWIW, they completely redesigned the engine a few years later, but never notified anyone to watch out for these common problems or offer a recall

Illuminated wrench light followed by malfunctioning speedometer, cruise control, & turn signal cancellation. Delayed and no gear shifting including an unexpected transmission downshift to 1st gear occurring at 40 mph: rear wheels locked up, engine revved to redline, had to put hazard flashers on and shut engine down in heavy moving traffic. Finally Check Engine/Malfunction Indicator Light (MIL); later reading P0720 code.

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!!!!!

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 -€œtiming 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.
