Mustang Bumper Antenna Issue
Summary of the thread
A 2022 Ford Mustang owner is experiencing issues with the keyless entry system, which is intermittently failing and sometimes requiring the key in the ignition. The problem is suspected to be related to the bumper antenna, possibly due to a faulty cable or connector. After checking the connections and finding no visible damage, the issue was resolved by replacing the bumper antenna module's cable at a workshop.

Yep, dove into the wiring harness myself. Connectors look clean, no visible corrosion or damage. Radio reception seems normal, which is adding to the confusion. Did your radio signal go haywire too, or was it purely the keyless entry?

In my case, the radio was unaffected, which initially threw me off. It was solely the keyless entry and push-button start acting erratically. Considering you've already checked the connections, I'd suggest getting it scanned at a workshop. Could be a deeper issue with the antenna module itself.

Appreciate the insight! Dropped it off at the shop, and you were spot on. Turns out it was indeed the bumper antenna module's cable. 95€ later, and it's back to normal. Thanks again for the help!

Interesting. I've got a Mustang, though not a '22, and I experienced something similar with the keyless entry and remote start acting up. Did you check the antenna connections yourself? Any sign of corrosion or damage? Is your car radio signal also affected?
