Haven't had luck with any videos, forums, repair shops, etc. Decided to see if anyone here had a similar problem with a solution. Car: 2013 Ford C-Max Hybrid May 2019: Started making popping sounds randomly through the speakers even when stereo was turned off. When stereo was turned on and the popping happened, the sound would immediately stop working. Display still worked, buttons still worked, just no sound. This was quickly fixed by turning off the car and turning it back on. December 2019: Popping sound got worse. It was like a constant stream of pops at this point. The radio pretty much never worked at this point. Display and buttons still worked. January 2020: Popping stopped completely, but now the display doesn't respond to the buttons. Time and date are still on, but the stereo screen doesn't appear when I push the button. When I push the button a second time, there's this little animation that the screen would normally show when the stereo was being turned off. The rear parking sensor alert sound has also stopped working. I'm curious if this is a speaker issue... I've taken apart the system but haven't seen anything unusual or out of place. All fuses are working properly, too. The dealer hasn't been much help, and a couple independent repairs shops have said the model is "too unique" to know for sure if they can fix it. ? Please let me know if anyone has any ideas!

I've used parking assist 100s of times before, and I love it. I've never had an issue with the technology and it's performed flawlessly when parallel parking into even the tightest of spots on either side of the street. Until today. Today was different.... I was backing into a (pretty darn big, relatively speaking) spot behind a lifted truck of some description, possibly an F150. My warning beeps never got beyond the 2nd phase (of the 4 phases - slow, fast, faster, flatline) so I kept on backing in slowly slowly... until the passenger side fender, all of a sudden, dinked the rear driver-side bumper of the truck. The resulting dent isn't huge, but the paint did crack so I've got a feeling my bill is going to be pretty darn high! Now, yes I was pretty close to the truck but the parking assist has backed me into some curiously small spots in the past without issue, so I just assumed it would do the same thing here. So, here's my question... do the proximity sensors only detect objects that are directly in front of them? Or say, 180° around them, in a straight line? For example, in this scenario, did they only detect the rear tires of the truck and not the rear fender 'cos it was lifted? Any insights would be much appreciated!
