What Owners Say
"I was operating the Ford truck on I 95 and a light came on telling me the truck was losing power and shut down. Had it towed to a Ford service center and was told the problem was caused by contaminated fuel. The fuel was checked and found not to be contaminated. Ford still refused to repair the truck under warranty. The cost of the repair was $8,000.00. I filed a claim with my insurance company the result was the cause of the problem was not the fuel, so they did not repair the truck. What I discovered was the high pressure fuel pump on 6.7 diesel engines will not hold up pulling heavy loads regularly and break down shredding metal thru the fuel system.. I am aware of others who have had the same problem with Ford on this same engine. I have pictures of the problems and did research of this problem with this engine fuel system. Ford is using contaminated fuel as an excuse to not repair their vehicles. My truck on had 33,000 miles on it when the problem happen. My friend had 25,000 miles when he had the same problem. I received a call from an individual in Texas telling about the same problem. I have posted on the web about the problem with Ford and the 6.7 diesel engine. This is something I would like to see CR look into. If you have any questions please contact me at 910-584-3452 or email: email@example.com."Walter V., NC (2016 Ford F-350 Lariat 6.7-L V8 diesel)

"Cold weather broke sensors. Took a week to diagnose and fix"Anonymous, NE (2016 Ford F-350 Lariat 6.7-L V8 diesel)

"Warnings that my speed would be limited to 50 MPH because of a loss of communication with a nitrogen sensor. First trip to the dealer replaced the sensor. Same problem, so 2nd trip they replaced the input module. Same problem occurred a 3rd time, so the dealer replaced with wire harness between the two. That finally fixed the issue. The on dash warnings were really annoying. I don't understand why Ford intentionally hobbles the engine for a loss of sensor. Why don't they just light the 'check engine' light and use the last known good value in any calculations?"Scott W., CT (2016 Ford F-350 Lariat 6.7-L V8 diesel)
