NHTSA Complaint #11688214 — 2015 FORD F-250

Noted strange "thumping" sound in truck. Took to certified local mechanic who has worked on our vehicles since 2016. This truck has just over 117,000 miles, I am the original owner (ordered while stationed in Afghanistan) and there has never been an accident, there has been no reason for removal of the body from the frame unless the Ford dealership who repaired the missing wire harness when the truck was less than 90 days old had to remove the truck bed. Inspection of vehicle noted the bolts holding the body to the frame were missing. Vehicle is currently being repaired. The risk is the body could have come off the frame and potentially caused bodily or property damage. I contacted Ford but have not received any feedback other than the call center laughing at me for the situation. There were no warning lights on the dash nor codes given to my scanning tool by the vehicle. Mechanic stated this is the third F-Series of this generation they have seen this year with the exact same problem. Truck cannot be moved due to safety concerns, locked out/tagged out of service. Repairs will cost approximately $2,500 including time and materials.
