One problem related to engine exhaust system has been reported for the 2005 Ford F-250. The most recently reported issues are listed below.
I have a 2005 Ford f250, 6. 0l diesel. This power plant is used on several Ford model vehicles and has an inherent problem with it's egr system. When the egr system fails, the vehicles looses all throttle response. Resend 03/05/10. On November 25th, 2009, I was stop at an intersection waiting to merge onto a very busy highway. When the time came to merge onto the highway, my vehicle fail to accelerate, it crept into the path of on coming traffic and I had to perform an advasive maneuver (immediately pull off the highway) to protect me and others from a potential accident. This situation has happen to me on more then one occasion and is intermittent. When I reported this to my dealership, they performed a procedure to clean out the carbon buildup within the intake system and told me that this was considered routine maintenance, this is not mentioned anywhere in the operators manual. I believe this is a public safety issue that Ford should recognize and provide a fix.
