Anonymous, TX (2012 Ford F-250 Lariat 6.7-L V8 diesel)"CHECK ENGINE LIGHT CAME ON and IT TOOK FOREVER & EXPENSIVE REPAIRS TO GET IT OFF -FOR NO APPARENT REASON !!"
Mark G., TX (2012 Ford F-250 XLT 6.7-L V8 diesel)"TheEGR software shut my engine down - completely, along the side of the road leaving me stranded. It was discovered it was a software problem from Ford. Poorly engineered system"
Anonymous, KS (2012 Ford F-250 Lariat 6.7-L V8 diesel)"Sensors failed on the system. System did not fail--but sensors said they would fail. Ford replaced sensors. Truck is going in again this week for another sensor failure on the exhaust--another one what will shut engine down completely"
Jay N., OR (2012 Ford F-250 Lariat 6.7-L V8 diesel)"EGT sensor went bad. Computer commands engine shutdown after notifying you that you have 45 seconds to get to safety. This could get you killed if you were on a busy road with no way to get to the side"
Anonymous, TX (2012 Ford F-250 Lariat 6.7-L V8 diesel)"Message came up and said pull over immediately. Truck died and would not start again. Called AAA"

John C., OK (2012 Ford F-250 King Ranch 6.7-L V8 diesel)"I had a engine ex host temperature sensor go bad. Also the DEV sensor went bad"
Anonymous, CA (2012 Ford F-250 Lariat 6.7-L V8 diesel)"We have had 4 sensors on the exhaust system fail. The system didn't fail; the sensor did. 2 problems we encountered will shut down the engine--unacceptable safety feature when far from home and out of cell range!"

Anonymous, FL (2012 Ford F-250 Lariat 6.7-L V8 diesel)"EGT sensor maybe falsely signals too high of a temperature and the computer flashs a message STOP SAFELY NOW.

"I have had problems with this since I purchased the truck. Fortunately it was covered under warranty but I had to fight to get it paid for by Ford. This is a common problem."
