Six problems related to engine exhaust system have been reported for the 2015 Ford F-250. The most recently reported issues are listed below.
The truck has 87,000 miles and I was driving 45 mph, engine light came on the truck jurked like back fire, no brakes no acceleration . Went to the nearest dealer they said the exhaust valve stuck and through the rod through the piston and cylinder wall. Ford says sorry need new engine 10,000. 00.
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.
I have a 2015 Ford F-250 super duty with a 6. 7l diesel. I started having this problem intermittently and only noticed it on hot days while at slow speeds, but it has continued to get worse to the point that it happened with every re-gen, at any outside temperature and almost any speed. It all starts with the notification on the screen of clearing the exhaust filter and has an ok in the corner of the screen. Not sure why the ok, since you have no choice on whether to start the process or not. During the re-gen process the engine suddenly and without any notification, looses power, starts to shake and shutter so violently that it shakes the whole truck. The only way to stop it is to put the throttle to the floor. If I let off the throttle it starts over again. The two safety concerns that it causes are the sudden loss of power and my truck suddenly slowing down without any brake lights to warn drivers behind me (I was almost rear-ended last time it happened in town) and secondly, having to keep the throttle on the floor to stop the problem and the speed the truck obtains when doing so. There are times when I cannot step on the throttle because of the speed limit, traffic or road conditions, and am forced to pull over if there is an area to so, if not I keep chugging along holding up traffic until I can. I have not pulled a trailer as of yet, but quite frankly an afraid to do so with this problem for fear of being rear-ended. It occurs at speeds from 30 to 70 mph. It has happened in town on rural roads and on the highway. It has been into Ford several times and they have not been able to fix the problem. The last time it was at Ford, the service manager told me Ford is aware of the problem and will be coming out with a software revision, but not until April of 2016. The truck is unsafe to drive until then.
Exhaust region caused extreme rough running engine and loss of power when towing up hill and passing a semi. This caused the semi to almost hit the back of my trailer. This continues to occur with every exhaust regeneration on the 6. 7 powerstroke diesel.
Exhaust regeneration causes engine shake and loss of power. The last incident occurred when towing uphill and a semi almost took out the back of my trailer. Ford indicates this is normal, however, it did not do this when new. It occurred after approximately 6,000 miles and continues to happen. The dealer indicated they have not seen this before, so I don't believe "normal" applies here. If this is "normal," then Ford engineers need to go back to school.
While driving down the high the dash display indicated it was start a exhaust clean cycle (regen mode). Within a minute the vehicle began stuttering, loss of power and the engine began knocking. The vehicle lost 15 mph in a blink of an eye. A very dangerous situation while towing an RV. This lasted for about a minute. Then the engine began to operate normally. This has happened multiple times since the first event. The last occurance was on August 16th. The vehicle has been taken to Ford service for an evulation.
