Pre-Purchase Guidance and Thinking Points

[Firn]

My 2025 Lariat ER has been at the dealership 3 times now due to them trying to get a brake controller to work. Ford says it won’t work but the dealer assured me they could do it. First trip they said they must have got a bad module from Ford (I don’t believe it) and the second time they “got a good module but the dash slider for the gain wasn’t good”. Now it’s back in for the third time and they still can’t make it work. I told them to forget it and put it back to factory settings and I’ll just get a Curt Bluetooth controller. Now they are having to work with Ford to get my computer back to factory settings. It has been an absolute nightmare.

I really want the OEM controller to be integrated into the truck but from all that I have read it just can’t be done without the Max Tow package…which is STUPID! Ford really started dropping the ball on needed features in 2024.

My thing is how can some random dude on the internet with FORSCAN make it work but an actual FORD dealer can’t? It’s just frustrating because I’m not going to go into the computer and poke around and potentially void my warranty. It’s just mind boggling.

I understand, but that doesnt change the fact that some dude with a computer HAS done it better than the dealer.

Fwiw there should be nothing about FORSCAN that voids the warranty. Forscan isnt "jailbreaking" the software, its just changing Fords own configuration file. Its how Ford changes the trucks to meet different markets, different configurations, or different features. You can go right to Fords website and download the configs.

Thanks for the heads up. I’ll hold out for the package. Sorry it’s not worked out for you too.
