You needing a re-flash wouldn’t have anything to do with the chip shortage, was likely just a bad version of code that got shipped out on a subset of trucks or something and they needed to get it updated.In April 2021 I ordered a new 2021 F-150 XLT Sport SuperCab. Surprisingly it was delivered to my dealer in 8 weeks. Everything was perfect and the truck was delivered to me on June 8, 2021.
I like all the technologies that are available on new vehicles. Ii added the new truck to my FordPass app on my phone. Immediately I received a FSA (Field Service Alert) concerning the Gateway Module re-flash.
I mentioned this to the service department and assumed it had something to do with the "chip shortage."
4 weeks later, I received a letter from Ford telling me to schedule an appointment for the re-flash.
Meanwhile my truck was operating as advertised with no issues. After the completion of the service I saw no change in how the truck performed.
I did have to delete the vehicle from FordPass, do a complete system reset, add the new vehicle and reprogram all my person preferences.
I was told the change is how the ECU data is made available to Ford.
