Does anyone know how to replace the backup sensors on the sedan? I've been having issues lately where my backup sensors stop working one day and work fine the next. I'm pretty sure it's one of the sensors but not sure. They're pretty cheap, so if it's easy to replace I'd like to try it out.
Thanks!

Have you checked to make sure they are clean with no obstruction/debris/grime?

Yeah, I completely cleaned the car, and still wasn't working, then a day later they started working again. I never had this problem even when they were dirty.

At least you tried the obvious and you gave it an attempt. Much more than some others who hang out here, and I thank you for that!

Anyone have a how-to on this. I am also having this problem. They are not operable more often than they are. I cleaned mine also.
