    If it's a different module why not disconnect it and see what happens?
    Seems that if you leave it noisy, you will also lose your rear cross traffic alert, since the parking sensors are always squawking when you're in reverse.

    "My car has the accessory package rear parking sensors, these were installed after the car was manufacturered, at the dealership when it was brand new.

    This accessory package does have a warranty period, but mine is already past warranty, it's shorter warranty than the car because it's an accessory part.*

    I realize they were installed by a dealer*but were they installed before the car was delivered to the original owner? If the answer is YES, then it would seem to fall under the warranty for accessories as shown below and be covered.

    Mazda notes that all Genuine Mazda Accessories, if installed by the Mazda Dealer prior to or at initial vehicle retail delivery, carry the same new-vehicle limited warranty as the vehicle.

    3-A silly question...is the cross traffic alert also a Mazda accessory and not a factory option? That kinda makes no sense to me that they use the same sensors, because my cross traffic alert uses the Blind Spot Monitoring sensors, and I don't have rear parking sensors.

    (What a goat rodeo.)
    1.) Correct, I get two warning symbols that pop up on the display and the car beeps differently enough over the constant beeping that I can tell the difference, it's a faster kind of beep, and it works just fine.

    2.) It's $600 for the kit, and then there would be labor on top of that, I didn't get a quote for the labor, at that point I just decided let's leave it alone for now.

    3.) The rear cross traffic alert is a standard feature for the Grand Touring model I think, not an added accessory. You might be right about that, about the sensors using the blind spot monitoring sensors and not the rear parking sensors. I wasn't 100% clear on that, but you are probably right. We concluded that it's best to just leave it as it is for now anyway. Honestly, the beeping isn't that annoying. It's not a big issue to me, and I didn't want them to take apart other things just to see if disconnecting it would disable anything else, best just to not take the chance IMO.

    I just didn't want to take the chance honestly, it would have meant taking parts of the car apart to get to it, and honestly it's just not a big enough issue to me to disable the beeping, the rear cross traffic alert works and I didn't want to take the chance of losing that feature.

    I don't know the answer to that honestly. I have no idea who the original owner is or what they did.

    At the end of the day, I'm ok with the results, if I ever want to in the future I can have it fixed properly, right now I need to just make my car payments

    I want to thank everyone for your interest and feedback, at least I'm now informed on the situation.
