Three problems related to check engine light on have been reported for the 2008 Ford F-350. The most recently reported issues are listed below.
Exhaust temperature sensor will cause a crash that may end up killing someone. This is what failed on my wife who was pulling a 28' horse trailer with her show horse inside worth over $30,000 dollars. She merged to a one lane road on interstate 68 in maryland heading down hill when the check engine light came one soon to follow with a message of pull over safely. 20 seconds later, the engine shutoff. This caused her to lose power steering on a one lane road going over a bridge down hill pulling a horse trailer with a gross weight of over 10,000 pounds. She had no where to pull over safely when the truck shutdown on her. She had to get out of the truck in order to move the barrels blocking the right lane in order to try and get the truck and trailer out of the open lane. She had to block an exit in order to make room for the other vehicles. The truck went to the Ford dealership in cumberland, MD where it was diagnosed that it was the exhaust temperature sensor. This is a safety issue on this vehicle. At no time should a vehicle shutdown on someone driving it. Believe it a vehicle going into a limp mode but at least you can still drive it so you can get to a safe place. There needs to be an investigation into why this occurs and enforce Ford to issue a recall to fix this problem before someone is injured or killed.
On September 30, 2014, my wife was on her way to columbus, ohio in her 2008 Ford f350 super duty turbo diesel truck (VIN# 1ftww31r68ea85755) with 44,000 miles. She’s pulling her 2014 26’ lakota two horse trailer with living quarters with her show horse in the back. The unexpected happen while she was on MD-51n near cumberland, maryland heading across a bridge with heavy traffic at 1230pm. The check engine light came on with the following message “pull over safely”. Twenty seconds (20 seconds) later, the truck completely shut down. Wife was traveling at 70 miles an hour when the truck shut down, which turned the power steering off. This is what I call unsafe for anyone, especially when pulling a 26’ horse trailer with an extra 1000lbs in the back with a horse. She was not able to get completely off the road which almost caused a major accident due to the vehicle shutting down on her. After sitting on the side of the road waiting for aaa to come tow the vehicle for over 1 ½ hours, the vehicle started back up and she drove it to Ford cumberland, 10335 mt savage road NW, cumberland, MD with the check engine light still on with a police escort since the sheriff of cumberland sat with my wife on MD-51n waiting on aaa. This is after she was almost hit by a fedex eighteen wheeler due to not being able to get to a safe location for a truck and horse trailer due to the vehicle shutting down on her. The dealership found the problem: exhaust sensor. They were able to repair it and she was able to continue on with her trip. How can this sensor go out on a truck with only 44,000 miles on it? how can they design a truck to shut down automatically without any warning? the dealership told my wife they have seen these sensors go out at 20,000 miles before. Needs to be address and recall issued before someone dies on the highway due to this problem. Hold Ford accountable.
Ford f350 with 6. 4l diesel had check engine light (cel) illuminate while driving. Engine immediately slowed to idle (800rpm) and would not respond to throttle inputs. Was not able to clear roadway and blocked traffic on busy urban road. Dealer was "not able to find anything wrong", yet "performed calibration update on pcm". I was informed "this needs to be done as vehicle ages and sensors wear. " reviewed owners manual and did not located maintenance interval for "calibration updates to pcm. " I am certain this is an inherent pcm software code error leading to complete loss of engine operation. A dangerous situation on congested roadways.
