NHTSA Complaint #11552464 — 2017 FORD F-350 SD

2017 Ford F350 Superduty 6.7L diesel will intermittently surge/buck while towing uphill under load causing loss of power and creating unsafe driving situation. When it happens I’ve also observed electrical power loss to OBD-II port where I have accessory guage installed to monitor critical truck systems like oil temp, trans temp, coolant temp, etc.. No DTC or fault codes are generated when this happens. I haven’t taken to dealer yet but I’ve researched and read lots of truck forums where multiple Ford owners have had the same issue. When they’ve taken their truck to the dealer they’ve been told this is “normal”. I don’t agree and believe this is a serious safety issue to a consumer that suddenly loses all power and must let off all acceleration while other cars are following/around vehicle when vehicle surges. This has now happened four different times and various speeds (30-60 mph).
