FUEL/PROPULSION SYSTEM
Vehicle Safety Complaint – 2021 Ford F-350 I am submitting this complaint regarding a safety-related failure involving my 2021 Ford F-350. While driving under normal conditions, the vehicle suddenly entered “limp mode,” resulting in a significant and immediate loss of power. Approximately 20 miles later, the vehicle completely shut down, leaving me stranded and requiring the truck to be towed to Gene Messer Ford for diagnosis and repair. The failure created a potentially dangerous situation, as the loss of power limited my ability to maintain safe speeds and respond to surrounding traffic conditions. After the vehicle was delivered to the dealership, it took approximately one week for inspection and an additional two weeks to complete repairs. During the repair process, I was informed that newly installed components—including the fuel rail and two fuel injectors—were defective and required replacement again. This raises concerns about whether the root cause of the failure was properly identified and whether contamination or systemic failure within the fuel system was present. I am also aware of widely reported issues involving high-pressure fuel pump (HPFP) failures in Ford diesel engines, which can result in catastrophic damage to the entire fuel system, including injectors, fuel rails, and lines. Given the nature of my vehicle’s failure and the components involved, I am concerned that this incident may be related to a broader, known defect. This type of failure—sudden loss of power followed by complete shutdown—poses a serious safety risk, particularly if it occurs at highway speeds or in high-traffic conditions. I am requesting that this complaint be reviewed as part of a broader investigation into potential fuel system defects in Ford diesel trucks. I believe this issue may warrant further scrutiny and possible recall action to prevent similar incidents.

ENGINE
Cold side intercooler boost tube cracked due to constant vibration impact from coolant overflow hose routed directly above and on top of it. Part and vehicle is available for inspection. The split in the boost hose caused me to loose power while attempting to merge onto a road, almost being hit by another vehicle. After research there are multiple other instances of complaints of the same thing happening to others and multiple aftermarket manufacturers producing replacement and upgraded parts with references and warnings of the same thing happening for the last 10 years. No warning lamps or symptoms prior to failure. After failure no warning lamps but could hear an audible hiss. The vehicle has not yet been inspected by the dealer or police. I was told by their parts people it is a regular failure and the part costs typically around $200 and they only sold it as a full part and not just the rubber replacement hose althought they are separate parts connected with hose clamps.

UNKNOWN OR OTHER
Back up camera screen goes blue when put in reverse. Then after 20 seconds says camera unavailable see dealer. I had dealer repair with a software reset. Worked for about 2 weeks then same symptoms. Noticed Ford has a recall for the same symptoms on other vehicles but for some reason F-350s are not a part of it. Would suspect the truck uses the same camera system as the other ford vehilces under the recall. Ford needs to step up and cover the F-350s

BACK OVER PREVENTION: REARVIEW SYSTEM BRAKING, LANE DEPARTURE: BLIND SPOT DETECTION, UNKNOWN OR OTHER
My Ford F350 is experiencing the recall deficiency issued by Ford in January 2025 after repeated calls Ford still is unable or unwilling to fix my vehicle. Ford motor company, and the local dealership have told me workarounds could be performed, but they would be done at my expense. A rearview camera on a pick up truck is used often and is a safety hazard when backing up Blind to low objects.
