problem #104

Jan 142017


  • 68,000 miles


In warm weather the truck suddenly shakes and downshifts to first gear no matter what speed you are going. The speedometer stops working, a wrench is displayed on dash sometimes. The speed after doing this does not exceed 20-25 mph. If we can safely get to the shoulder of the road and turn truck off and restart it everything resets. This happens atleast once daily, sometimes more than once daily. It always happens when truck is in motion. It does not matter what speed as it has happens at different speeds and on one occasion when I was in the process of stopping for a red light. The last occurrence happened today, but it has been happening for several months. When it is cold outside it does happen less, maybe once weekly instead of multiple times daily when the weather is warm outside.

Transmission downshifts down to 1st gear locking rear wheels and causing vehicle to go into a skid and loss of control. Vehicle was traveling 70 mph on interstate when this happened and was captured on video as to how the gauges responded.

The truck suddenly decelerated and a warning light came on. The first time I was on a residential street and went from 25 to 2 mph w/O any other traffic. The second time it was on a state highway and we went from 45 to 2 mph with traffic behind us. The dealer said the throttle body needed to be replaced because of a bad sensor. This is apparently a known issue on 2015/2016 model years, but not on 2012's. the dealer said it is the same problem and Ford has recalled newer trucks because of it.

The rpms then rapidly dropped down to 1,500. The vehicle was driven to a mechanic. The vehicle was diagnosed as a "P-1500". the vehicle was not repaired. The manufacturer was not notified. The approximate failure mileage was 77,000.

My F150 is constantly experiencing the exact dangerous malfunction that safety recall 16S19 describes. Ford is not providing any rental assistance and currently does not know when a solution will be available. My transmission will have issues shifting to the next gear, rev up way farther than necessary to shift and then stall. I have to turn off my truck and turn it back on several times to get rid of the issue just to get me to my destination. This occurs on 50% of my drives around the city. I will not dare take it further than 10 miles in fear that I might be stranded and forced to pay for towing. Ford has also told me I must prove something is wrong with my vehicle to even apply for a rental. My local Ford service is not able to find anything wrong besides the exact issue I'm describing. It's a pandora's box, built to put the consumer in the worst position risking injury or death driving a faulty vehicle or paying the bill for a rental.

20,484 miles on truck. 10/18/15 RPM's increase but doesnt shift into next gear. 10/19/15 roadside assistance towed to dealer. Dealer found no code, sent back to me. 11/17&11/22 driver seat lost memory. 11/28/15 RPM reved when brake was applied RPM's were still increasing. 12/2 brought to dealer no code on diagnosis, sent out again without troubleshooting 20,900 miles on truck. 12/8/15 RPM's reved didnt go into gear. 12/8/15 1hr after prior failure, tried to leave driveway and 2 attempts to engage drive it wouldnt move put truck in reverse then proceeded to put in drive, stuck in 1st gear for 2 blks. 12/10/15 my 5yr old granddaughter and I drove 4 blocks before truck shifted to 2nd gear. 12/11/15 truck did not seem to be running right heard a clunk upon leaving prk lot got across 4 lanes of traffic and truck failed to shift, wrench on dashed showed and went away, dash info had lines across instead of mpg and air bag light stayed on, dealer was on my way, this time code showed and was the torque converter. I ended up driving this vehicle 500 miles iwith the torque converter failing here and there until a code showed. This caused a very dangerous condition to all on the road and much unneeded stress. I am very concerned what other components have premature wear due to continuing to drive my truck in this condition. I purchased an extended vsc from dealer but unsure what it covers so Ford will not offer extended warrenty, only offering oil changes. I do not want anyone to go through this same dangerous situation. Please act on this before deaths start occuring. After reading up on the torque converter, the symtoms my truck experienced were exact along with the truck increasing RPM's although brake was applied. Instinct is you dont continue driving a vechile that doesnt shift even due to likelyhood of other components failing and dangerous conditions in traffic.

I purchased a new 2012 Ford F150 platinum 4X4 ecoboost truck in June 2012. Around 2014, I experienced a complete loss of power and major shaking or shuddering when I went to pass a vehicle in the highway. I thought it was a misfire issue and called the Ford dealer I purchased it from. They asked at the time if it was consistent and I said it was not. They advised that I should just keep an eye on this and that I had an extended warranty. I was told to bring it in if it continued. I have also done a good number of all maintenance related check ups and services with the Ford dealership I bought the vehicle from. It happened a few more times over a 1 year period. I changed the spark plugs as I thought it was a misfire but it continues to happen. The last episode nearly resulted in a collision. I took my vehicle to a Ford dealership near my home and they tested it. Computer reading says it is a P04300 - bad inner cooler. Fix is $1700 per dealer (new inner cooler, new catalytic converter, new boots, new plugs and adding a shield) but that since I am now at 88K, emission warranty ended at 80K and I have no financial support from Ford. I advised I was never told about an emissions warranty and that this is not my driving or mileage issue and that Ford acknowledges this is a design flaw in the charge air cooler and had a redesign. This is a major safety issue and if Ford recognizes this as their design flaw and is now happening to my Ford vehicle, I need them to help accept this as a warrantable item and accept the repair from the dealership. Please assist. Kindest regards.

F-150 4WD 6-cyl

  • 55,000 miles
When there was snow and ice on the highways I put my truck in 4 wheel drive and when turned back into 2 wheel drive I began to notice a grinding and vibration noise that occurred when turning. Then couple weeks later the noise started when backing out causing truck to shake and lose power to barely back out. This noise continued and has gotten worse. Was taken to dealership and looked over. Updates were made as well as oil change but days later noise came back. Since 2/12/15 my truck has been in the service department four times and has performed recommendations by Ford but days later noise comes back. The last time my truck was in I was told by the owner and service manager my truck is not fixable as they were informed other 2012 F150's are having same issues and an investigation is being done. Since this my truck is shaking more backing up, jerking the vehicle on the highway as if losing power than will gain power and jolt forward, I hear this grinding noise all the time when driving at different speeds from 30-60 mph, turns, and backing up. The other issue is when truck gets to 60 mph or higher it does not shift down unless I let up on pedal and then push it again. I am feeling unsafe in this vehicle as twice now I have heard a popping noise while driving with this noise. The dealership has told me there is nothing more they can do. The issue has been reported to Ford and they have done nothing for me. I want to get rid of this truck as I do not feel safe driving it like this.

Multiple occasions go to step on the gas and the truck just doesn't accelerate, feels like a misfire or almost about to stall, this usually happens when at a complete stop at a light and light turns green, has also happened when rolling in traffic or trying to get onto highway at the on ramp. Another time driving on highway, stepped on gas and truck lurched forward as if someone hit me from behind and RPM kept accelerating even though I was not stepping on the gas. Have brought this to dealer and they claim they can't find anything wrong. I believe these are particularly dangerous because I'm expecting the truck to move so I can go along with flow of traffic and it just hangs on me putting me in a bad situation or it launches forward making me momentarily jerk the wheel and lose control. Possible known issue? (www.usatoday.com/story/money/cars/2013/05/28/Ford-F150-ecoboost-government-probe/2367197/) thanks

I was with my family on the way to church. I was making a right turn out of our neighborhood onto the highway when all of the sudden there was a complete loss in power and was unable to resume acceleration. The highway also has a moderate incline in slope which caused the vehicle to slow dramatically. We were almost rear-ended from the car heading in the same direction which was originally a substantial distance away. Luckily the car that was approaching from behind was able to slow down fast enough considering we had a 1 year and 4 year old son in the back seat. I called the local dealership and the earliest appointment they could offer to check the problem was on Wednesday 10/10/2014. This is over 3 days after the incident occurred. The truck only has 40,000 miles on it so I began researching this issue. I discovered that there are more than a substantial amount of complaints and it seems Ford is aware of the issue and is even attempting to modify the air induction system and re flash the PCM. With issues like the millions of vehicles being recalled for airbags that have led to serious injury or death, far beyond the manufacture originally becoming aware of the issues. How long is the issue regarding the 2011-2013 Ford F150 ecoboost going to remain shoved under the rug? how many lives have to be lost before Ford takes accountability for putting the public at risk. In their report to this specific issue (on the NHTSA website), it is more than obvious they have identified a defect in the 2012 Ford F150 and the ecoboost engines within the trucks. Can you help me understand how and why they are not being held accountable for risking the lives of many people. Also, why is the NHTSA allowing Ford to shrug this off and close this investigation" there is a clear defect present that has the potential of leading to loss of life. Is this not pure negligence"

When you press the throttle pedal to pass the vehicle has a slight acceleration and then shakes, shudders and will not accelerate. I need to coast for several hundred yards before the system recovers and the truck accelerates. This happens all summer long pretty much every time I need to pass. My Ford dealer says they have applied the service bulletins but that does not correct the problem. In your investigation of this matter it is stated that Ford says you can still accelerate I can tell you that is absolutely not true with my truck. I should note that most of the time I am pulling an 18' fishing boat that weights about 3000 lbs. On at least six different occasions now while on vacation I have been in a long string of traffic behind either motor homes or logging trucks that could not go highway speed, I pull out to pass them step on the gas, it shakes, shudders and there I sit in the oncoming traffic lane, meanwhile the string of vehicles behind me have closed the gap, I cannot pull back into the right lane and I cannot accelerate to get in front of them. I end up just slowly moving back to the right hoping the other vehicles will back off and move out of the way, then comes the blasting of their horns and shaking of their fists when they eventually pass me. I cannot imagine how this is not considered a safety issue. Ford specifically markets this ecoboost engine based on it's torque for towing to people that need a truck for towing but you cannot use any of that torque all summer long and I am pulling a boat that is only at one third of the towing capacity.

While getting on the highway and accelerating, my truck began to shake and lose power. I took it in to the shop afterwards and they had to replace all spark plugs and 1 ignition coil. After researching this, I found out this has been an issue on several 2011 - 2013 model eco boost. Please force a recall, as I do not feel I need to pay for something Ford is responsible for.

F-150 4WD 6-cyl

  • 48,963 miles
For the fourth time, my 2012 Ford F150 ecoboosted engine stalled or shuttered when hauling a load (trailer or heavy bed load) in a high humidity environment. I was pulling a U-haul trailer behind my truck and it was raining heavily. When I punched the accelerator to pass a slower vehicle, the engine stalled, sputtered, and nearly shut down. The "check engine" light came on for about a minute, then turned off once the engine had cleared what felt like condensation, and returned to normal operating mode. When I took the vehicle to the dealership to complain (for the 4th time), they told me that they were of aware of a design problem with the intercooler on 2011-2013 turbocharged vehicles, but since they could not verify the defect "code, " Ford would not reimburse them for the service fix. This is clearly a safety and environmental issue as the service bulletin that Ford issued to correct the problem, requires replacement of the catalytic converter as well. Frustrated!

While traveling at 55mph, up a slight incline on the highway, I pulled out to pass another vehicle. As I pressed on the accelerator I had no engine power and the F150, lariat, eco boost began to slow. The check engine light came on and flashed. I let off of the accelerator and then pressed it down again. This time I had power. I pulled back into the lane and everything appeared to be in working order.
