Had this identical issue with my 24 XLT PB at 5000 miles (3 months ago). Yup, the Gear Shift Module (GSM) is the culprit and a known issue. Should have been an easy fix, but the part wasn’t available….drove a courtesy vehicle for 6 weeks while they waited on the part. Super frustrating, but at least all the miles I drove went on the courtesy vehicle!Got this message on my 2024 powerboost with 6700 miles . Took it to the dealer, they cleared it , I picked it up and an hour later it came back on . Back in the shop . Very unhappy
Glad to hear you're getting good service. Hopefully, your part comes in soon and you're back on the road soon. It may be a stretch, but I'm getting a sense dealerships may be improving their service. Fingers crossedFinally got a call they are ordering a GSM . They ordered on Monday possibly on Friday, said they should get it today 8-12 . Not holding my breath. I think the dealership was trying to pencil whip it . I brought up I did research and fellow F150 owners have had problems with this GSM .
