Front parking sensor issues
 

Hi all
Just purchased a 2021 Outlander, Had the optional front parking sensors installed, ( By Mitsubishi )
My problem is these sensors alarm even when in park ??
The rear sensors beep/activate normally, and stop beeping when when taken out of reverse, Also dont beep when starting car, where the front beep/screem in any gear even park ( if anything is in range )
so i am unable so idle the car in a parking space without a constant alarm ? ( if any one is parked near )
how can this be ??
I've argued with the dealership that this cant be right but they say its normal,
So is my Dealer Mechanic telling lies or is this a terrible design flaw ??

Since the day i bought my car my front parking sensors like to randomly beep uncontrollably. It sooo annoying. Ive taken it to 2 places who refuse to do anything but ask me to pay 130-160 for diagnostic. How do i stop the beeping? And why have a button if its still going to beep at u at every stop and while ur stoped.
