Sports Bronco 2021
I bought a Sports Bronco 2021. I bought it in December 2021. I stopped to put gas and when I proceeded to start car, it started to blink car overheating, service now in a red lined box and it wouldn’t start. Then it kept changing screens with yellow boxes like it was going through a check of different systems. Vehicle wouldn’t start so I called Perry Ford and stated they didn’t know what’s going on with it and to call roadside assistance. I waited a few minutes and attempted to start it again which worked. I drove it to the dealership and informed the main gateway module failed. I have to wait four days for part and didn’t offer a rental car to me. 😩

I’ve googled it and I can’t find any information on this happening to sport broncos. I’m really disappointed as I thought this would be a reliable vehicle while I’m in the military in San Diego.

Has anyone heard of this happening? I was informed this part controls transmission amongst other main components of Bronco. Looking to educate myself, if anyone can shed light on this issue. Thanks

Bummer. The GM is the "crossover" for the various CANs, so without it the separate systems (body, powertrain, displays) can't talk to each other. This is what warranty is for...

It’s a bummer that this happened to you but you have searched here and yours seems to be the only one so far. Things do fail, even new things. As said above, that is why you have a warranty. I think that dealers aren’t’ offering loaners because they don’t have any cars on their lots.

Gateway Module

NOTE:
The GWM communicates with the 4 controller area networks (CAN). The OBD DLC is fitted to the GWM and is the direct interface with the scan tool.

The GWM is mounted under the driver side instrument panel. The OBD connector is fitted to the GWM. The GWM acts as a central gateway to translate messages across all 4 vehicle controller area networks (CAN), and vice versa. The GWM is the only module on this vehicle with this ability. The GWM also serves as a termination module for each of the networks to which it is connected.

Now I understand so much better. Yes, hoping this doesn’t happen again.
