Message #6-Pre-collision assist not available. I thought if I shut the truck off it would reset. When I tried to restart the truck it did nothing. Had it towed to Archie Cochrane Ford in Billings, MT. They replaced the DEF wiring harness. 2nd incident on [XXX], drove through rain on way to Provo, UT. Service engine soon light came on with all the same messages + five other messages. Had it towed to Larry H Miller Ford in Provo, UT. They replaced the Battery Junction Box. Drove to Yuma, AZ without incident but had them look it over and they could not reproduce the issue. Drove to Dickinson, TX, encountered fog on 1/3/2025. Incident #3, drove to the gas station on [XXX], started the truck up and the same messages came up. Roads were dry, although it had rained the night before. Drove straight to McRee Ford where the technician observed the issue firsthand. While the vehicle was in park it was constantly surging. We researched online for the same problem and have found others that have had this same type of issue. We have had to rent cars when the truck was in the shop. We believe this is an engineering issue and Ford should fix the issues without charging. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORM
