NHTSA Complaint #11536787 — 2015 FORD EXPLORER

The rear backup camera on our 2015 Ford Explorer began glitching, reversing the image, or going completely blank in autumn of 2022. We took it to a local Ford dealership on November 17, 2022 for service and was told the camera needed to be replaced. We waited days, then weeks for a replacement, and finally gave up after contacting a different dealership which had the same problem obtaining replacement cameras. We have heard about Ford recalls for this problem and searched online for information. It appears there was an NHTSA recall a few years back covering model years 2019-2020, and now there is a similar recall for model years 2020-2023. I have read of MANY similar complaints from vehicle owners of models 2014 to present. WHY AREN'T MORE MODELS YEARS COVERED BY THESE RECALLS? It appears to be the same problem?
