The contact owns a 2012 Ford F-150. The contact received a recall notice for NHTSA campaign number: 19V075000 (power train). The vehicle was taken to william mizell Ford (located at 330 us-25, waynesboro, ga 30830, (706) 554-2114) where the recall repair was performed. As soon as the contact left the dealer, the transmission started to jump when downshifting, and the engine stalled without warning. The vehicle was taken back to the dealer and test driven, but the failure could not be duplicated. The contact stated that he was not aware of the diagnostic testing, but was informed that he would need to drive the vehicle for a while for it to drive normally. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 91,000.

Tsb 15-0131 timing chain stretches and makes a loud rattle upon starting and eventually leads to loss of power and engine damage. The known cause of this is all the phasers, the intake and exhaust phasers. This is my main concern. Everyone I know who owns this vehicle has this problem. The other complaint is that I get 14 mpg.

I was driving on sr 71 North of columbus Ohio in the rain when I changed lanes and tried to accelerate but the engine just started shaking and my engine light started flashing. The truck would not accelerate and started to slow down. I managed to get out of traffic and got off the highway. After sitting a few minutes I tried to get back on the highway. When I tried to accelerate the truck started shaking and would not accelerate. After a 3rd attempt the truck finally got up to speed and I made it home. My engine light is still on. I began to read forums on the Ford F150 FX4 and discovered many many people are having this problem with moisture and the intercooler system.. I could've died today. This needs to be made right by Ford Motor Company.

When starting truck when hasn't been driven for several hours engine makes a loud growling noise for about 5 seconds before sounding normal. It had done it occasionally before 02/2019 but now does it daily. Some research on other forums that it is the tensioner on the timing belt. Truck with this low mileage should not be having these issues. Any input?

F-150

  • 52,905 miles
A ticking/knocking noise on passenger side of engine. Took to Ford dealer with 52,905 miles on 7/12/16 and stated fuel injector noise. Took to same Ford dealer on 11/7/18 for same noise, only louder, and dealer detected no unusual noise. Took to different dealer a 3rd time on 3/27/19 for the same problem and stated "noise found to be normal characteristics" and was given a copy of "special service message 47787 which addressed a "tick tap and/or typewriter noise at idle" issue. This problem was brought to the attention of Ford while it was still under manufactures warranty and the sound is only getting worse which is why I keep taking it to a Ford dealership. The sound is not heard when the vehicle is first started, only when it starts to warm up and is quite loud at an idle. If this engine were to blow up going down the highway or interstate could potentially cause an accident resulting in injury and/or fatal crash.

I bought it with @ 10,000 miles on the odometer. I have had nothing but [xxx] with it from day one. First off I put two new front rotors and brake pads all the way around and both idler pulleys were squealing so I replaced them. Then at @ 19,000 miles I had to replace both cvj half shafts. Now at 45,000 miles they are both shot again the cvj half shafts are. On the first of January this year I was driving down the road and the vehicle was running good suddenly it began to cut out and the power fell off on its face. I purchased an obd11 code reader to try and diagnose the problem. It tells me that random misfire detected and that cylinders 5 6 7 8 are misfiring. Let me just say that 4 months later after going thru everything from the plugs wires injectors and replacing the fuel pump module assembly it is still not running and I'm at my end of trying to get the peice of $*** running. There is no way in [xxx] at 45,000 miles on the vehicle that I should be having all the [xxx] with the vehicle. I live in New Mexico and we do have a lemon law here. I am beyond the shadow of a doubt sure that this truck is a [xxx] lemon.

My timing chain on my F1 50 was stretched and I paid over $8000 to have it fixed and here it is not even a year later and it is stretched again. With all of the supposedly new and updated parts Ford obviously doesn't care about what vehicles we buy because they clearly don't want us to buy theirs since I don't want to fix this problem the right way!

Truck currently has a recall on it due to it going into first gear unexpectedly. Took truck to closest dealership two weeks ago and had the recall service completed. Was told to expect my check engine light to be on for three or four days. When it stayed on a week I called them back to discuss the light still being on. Rescheduled a follow up appointment for April 12. On April 5 and April 7 the truck had the same problem that the recall was supposed to fix. Going approx 50mph when the truck went into first gear with wheel hop and some fish tailing. When this problem occurs the instrument panel will basically go to all zero's and it takes the truck being turned off for the computer to reset and allow truck to drive normally. Just wanted to document here since truck goes back to dealership tomorrow.

I was entering the interstate system by way of "on ramp". went to accelerate to highway speed (65 mph) and my truck began to shutter and loose power. I had to stay on the shoulder of the road to avoid getting hit by a semi truck. It eventually began to run normal.

2012 Ford king ranch 3.5 ecoboost F150 suddenly down shifts during acceleration. It is labored when accelerating, it gets to the 6th gear then suddenly down shifts.this happens when trying to merge on to the highway and also when coming from a complete stop after sitting at a light, then trying to accelerate. It has happened on the highway at 70mph trying to accelerate to 75 mph too. It seems like it loses power.

These trucks have now had 3 different tsb's on them for cam phasers and the timing chain stretching. When is there going to be a recall? tsb's I am referring to are: Tsb 16-0027, tsb 15-0131, and tsb 14-0194. This is completely out of hand. The fix does actually fix the problem with the improved parts, but these vehicles have failed and Ford is either replacing the engine or actually doing the work in the tsb. If a customer is out of warranty, they must pay for the work. This is not what Ford is suppose to be about and is a disservice to their loyal customer base. I have a 2012 F-150 3.5L ecoboost and I will never buy a Ford again unless they address this issue. It is a similar issue to the 3V 5.4L with phasers and the timing chain, which killed my 2004 F-150, so I have been effected by these issues twice now, directly.
