I have a 2012 Ford F250 king ranch 6.7 diesel. The radiator started leaking so I took it to the dealership only to find out I needed a new radiator. Since my bumper-to-bumper warranty ran out at 36K miles this repair was on my dime. In researching online forums and such, there have been known issues with the diesel radiator as far back as 2008. The entire premise behind a diesel engine is "compression-ignition" in which fuel is ignited due to compressed air at approximately 1000 degrees F. there is no scenario where the either the manufacturer of the radiator and/or Ford Motor Company themselves should not be required to fix this faulty part at their expense. The repair estimate was over $2,000 on a vehicle less than 3 years old. In no way should any new vehicle owner be required to pay for a new radiator much less for the labor to install it and that goes double for the owner of a diesel engine.

F-250 8-cyl Diesel

  • 18,000 miles
Red fluid found on garage floor. I took my truck in and Ford could not find any leak. Within a week later I took it back and showed them where it was leaking. Ford brought the master mechanic over and they determined that it was something loose on the right side up high they did not tell me what it was. Within a couple of weeks I took it back again and they determined the water pump was leaking they had the truck for 3 days. After picking up my truck within 200 feet from the Ford dealer the low power illuminated and the engine symbol lit up. They 1st told me they would have to take the top of the engine off to check it out. A hour passed and I got called and told it was the diesel fuel was gelling up and they would have to put a additive in the fuel and that I should add it again every other tank of fuel.

F-250 8-cyl Diesel

  • 450 miles


On 28 September 2012 I purchased a new 2012 Ford F250 diesel pickup from a Ford dealer. On/about 1 November 2012 while accelerating (from approximately 10 miles per hour speed) into an interstate traffic lane this vehicle suddenly went into an engine near stall/loss of power condition which lasted approximately three to five seconds and then regained normal engine power. This was a very alarming condition as I was entering into high speed traffic and needed capable acceleration while entering into traffic. The truck had approximately 450 miles on it when this first occurred. I took this truck back to the dealer when the truck had 551 miles on it and they could not find anything wrong. While driving the truck on 27 November 2013, this same engine near-stall event occurred under a similar highway ingress condition when the truck had approximately 5,100 miles on it. I called the Ford customer service hotline and was advised to take the truck to a Ford dealer for a second checkup. I then took the truck to a different Ford dealer on 6 January 2014 when the truck had 5,510 miles on it and they could not find the problem. Neither of the two Ford dealers that I've taken the truck to for diagnosis will provide me with a further course of action to fix this recurring engine malfunction. I want this malfunction fixed or a new pickup to replace it, it creates a personal safety hazard for me and my family and the problem has been in the truck from when it was only a month old and had 450 miles on it.

The truck engine will stall at low speed for one to five seconds, especially dangerous if you are trying to enter traffic. I have reported to northside Ford every time I have it serviced, they finally agreed that I have a problem, however they have failed to fix. I get the impression that Ford is aware of this problem, but for their own reasons do not want to fix it.
