Issues with cross traffic sensors

[Bmac1955]

2019 expedition xlt issues with cross traffic and rear sensors for backing up. Reverse sensors will work on screen and not show hazards after about 20 seconds. Has anyone had similar issues. I would assume the next step would be into the dealership for service. Clean vehicle not dirt or mud interference. Southern Cali weather operated in. 44,000 miles on vehicle. I have a feeling it is the module but just looking for opinions. Thanks!

Know issue, your sensor connectors are corroded… if under warranty it’s free, if not it’s a easy job
