2014 Ford F-150: shudder or vibration when accelerating

Filed Dec 9, 2025 · Transmission · TX

I had the OSS software recall completed a few months ago. Software fix is suppose to prevent automatic downshifting to 1st gear when traveling in higher gears. I am now having slipping/engine shudder when accelerating in higher gears. More than likely the lead frame will need to be replaced and my independent mechanic has said this should have been the fix initially, not just a software update. (Same models from 2011-2013 have had this recall implemented, but the 2014 has not been included for some reason.)

Truck has 46665 miles. When driving first 10 minutes (city driving) vehicle shudders, shows wrench indicator and goes into limp home mode (no accelerator). Have to pull over, turn off ignition and restart engine. Problem code shows p2112 (throttle actuator control system...stuck closed). This may happen 3 times in first 15 minutes of driving, but then goes away when car warms up. I have also noticed abnormal exhaust smoke and bad gas mileage. Having truck go into limp home mode in middle of traffic is very dangerous.

I was driving down the highway when my truck lossed all throttle power. A wrench icon came up on my screen and I had to pull off the highway onto the shoulder. When I stopped the truck was shuddering really bad and wouldn't move. I turned it off and restarted it. The wrench went away and it would move again. I took it to a shop and they told me the electronic throttle body was stuck in the open position. This is the second time I'll be replacing the same part. First time was under warranty this time won't be. But when this part fails it is very dangerous. If it had failed while I was crossing lanes of traffic I could've been in a accident. You lose all throttle control when it sticks.

This has truck has a shudder or vibration from starting out from 1 to 10 miles an hour and additionally when passing and driving on the highway. There is also an acceleration delay at all speeds. This truck is equipped with the 3.5l eco boost engine. These issues are especially more noticeable when there is a load on the truck such as a topper and luggage, etc.

As I was passing a truck the engine cut out, lost power the tach dropped from 4000 RPM to below 1000 and the engine shuddered violently. This has happened before and the dealer keeps telling me everything is working correctly. This time I took video of the instruments to prove it. The engine check light flashed all the time this was happening and then went out when the engine began operating properly.this starts after you try to pass a vehicle and it puts you in a dangerous position of being in the passing area and have no power to get by, this could lead to a major problem. I am a certified accident investigator and have been a police officer for 45 years. I am also a master mechanic, this has to be corrected by ford soon.

Vehicle exhibits a shudder/vibration/shake when starting from a stop. Problem is more apparent with weight on the truck. With approx. 400-500 lbs. Or more problem is most apparent. At 300 miles, the problem became very noticeable. Informed dealer, set appointment. Vehicle had 800 miles at servicing, 2/23/2015. Dealer removed rear driveline and drove the truck with just the front driveline and shudder did not occur. Dealer replaced entire rear driveline and problem persists. After 8 days at the dealer service shop, customer was told the problem is normal, especially with any type of load. 400lb is a load???? What happens when I attach a tow unit to this vehicle? Is this safe? After acknowledging a problem and replacing the driveline, dealer now says this is normal and has something to do with the shocks and computer. But rest assured this is normal. Waiting for ford factory representative to investigate. Problem is disturbing and one has to wonder what the long term consequences of this shudder is to the vehicle, vehicle driveline, etc. I was told numerous things by people at the dealer; salesperson said it was probably in need of a transmission reflash, shop foreman originally said maybe there was not enough grease on the driveline splines. Now it's the computer and the shocks? I asked the service mgr. Why they replaced the driveline if its a normal situation. He responded that they didn't notice the weight (400-500lbs under the tonneau cover) until after they replaced the driveline. One has to wonder about dealer competency when they apparently know a problems exist with weight on the truck, yet fail to check for weight on the vehicle. Also, is this not some sort of acknowledgement that there is a problem? As of 3/2/2015, the truck is still at the dealer. I've spent less than one week in the truck and over one week in a ram 1500 rental truck. No new car joy here.

2014 f150 ecoboost v6 - engine shudders and stalls upon rapid acceleration; issue has been addressed with "deflector shield" but this shield is already in place in my vehicle but the vehicle continues to have this issue - I feel the vehicle is unsafe but ford offers no assistance with resolution of the issue.

Was traveling behind two vehicle doing approximately 50 MPH in a 75. Went to pass and pressed the accelerator, and nothing happened. The vehicle starting shuddering, and stalled as I pulled along side the first vehicle. I let off the accelerator and attempted it again, still nothing. With loss of power, I had to move towards the shoulder since over taking the vehicle was impossible. The lasted for approximately 10 seconds, during which the check engine was flashing. Approximately 2 months prior, it happened while driving to dallas, but not to this extent. Weather condition for both incident was heavy rain, and I had been driving in rain for several hours. Engine code showed p0306 for cyl 6 misfire.
