Hi Experts,
All parking sensors on my Tucson 2018 stopped working.
Seems that the warranty will not cover it for the reason that a small rock hit one of the sensors .
My actually concern is that if one of the sensors will go faulty o believe that only part of the sensors will stop working (in my case front ), but the rear should not be affected .
Anybody knows if that is the case ?

Thank you!

 

I don't have a wiring diagram handy to check the circuitry, but Most sensors usually need a voltage supply to operate. If the damage caused the sensor to short internally , it might be a good idea to check all the fuses. Your owner's manual should tell you in the fuse /relay section which fuse protects the parking aid section.
Now,,, if you find a blown fuse and replace it , without correcting the cause for it to open , it will just blow the replacement fuse. If you do find a blown fuse , consider disconnecting the damaged sensor , replace the fuse and see what you get.
