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.

This engine with aluminum heads blew out spark plug numbers 2 and 7. First occurrence on Aug 11 2015 and the next Jan 14, 2016. The first incident occurred driving down a highway and the next occurred starting from a stop light. There was a lag in power and then a loud banging noise and a strong odor of gas. This created an explosion hazard as well as put my safety in jeopardy as well as that of those around me. Since the air/fuel mixture is being blown out of the engine on the compression stroke and the coil firing normally this created a deadly situation. This problem is known to Ford and the company is refusing to do anything about it for all vehicles with these particular engines that are having these problems. This shouldn't even happen with an engine. It's a manufacture/design fault. It needs to be addressed and fixed. The mileage is not the issue as these occurrences are happening on the newer trucks/suvs as well with way fewer miles. That shows it's a manufacture/design flaw and a very serious one.
