Truck was driving at 35 MPH when all of the sudden lost compression. Coasted off the roadway. Vehicle had broken valve spring which dropped valve causing hole in top of piston. This truck is in new condition with oil changes regularly no warning lights on the dash or knocks. Zero indications prior to this happening. We own four fords and believe this to be a faulty part. Thousands of dollars to repair. Only 92000 miles on it all highway.

Exhaust cleaning cycle causes extremely rough running conditions. Severe engine knocking seems as though a piston will fly through the hood soon. Significant loss of power at any speed during this time. Brand new truck purchased from dealership and this has happened from purchase point all the way through 27500 miles so far. In reading I have found thousands of others that experienced the exact same issue.

During regen cycle for diesel motor, vehicle begins to making a knocking noise and then begins to shake, and finally give feeling of losing power. Because of this, fearful the vehicle could encounter this situation at times where it could pose great danger. This occurs at various speeds and driving conditions. Issue was previously "addressed" in a bulletin from manufacturer; however, there is more to this condition. What vehicles don't idle or drive at highway speeds for a period of time or don't make short trips? Most recent occurrence happened on 8/15/16, but has been occurring for the two months-- is getting progressively worse in lei ration and force. Have taken to a dealership and they said they could find nothing wrong-- they didn't even act like they knew anything about the issue occurring and they definitely did not mention the precious manufacture bulletin tsb 15-0088. Have begun to research this issue and it appears an update was to occur in march 2016, but have not been notified of any issues? Needs to be looked at closely to ensure it is not a design flaw or worse.

Re: 2015 f250 sold to [xxx] VIN #[xxx] a few months after purchasing a new 2015 f250 diesel, I began to experience something wrong. When traveling at a constant speed, the engine began to knock loudly and the entire truck began to vibrate. After taking my foot off the gas pedal and coasting for a short period (there is no power to accelerate during this time), the truck seemed to function normal again. There were no warning lights or messages on the dash. The problem is getting worse and more frequent; lasting longer and loss of ability to accelerate interrupts flow of traffic behind me. I held up traffic going up ms river bridge, and this past incident lasted for a 15 mile stretch. It is extremely unsafe.......

When the vehicle is performing a regeneration, and you are going up an incline, the engine can shake and valve knocking can be violent accompanied by a loss of speed and power. The first violent incident that happened was going up a narrow mountain road and fortunately no one was injured. The vehicle has been taken to the ford dealership and contacted ford corporate multiple times and they are unable to correct the issue and unwilling to spend enough time to witness the issue themselves. The loss of power occurs unexpectedly and could cause someone to lose power while merging onto a highway which is unsafe or cause the vehicle behind you to rear end your vehicle when the power loss occurs going up hill.
