I just purchased a 2014 TL SHAWD with Tech, I have owned many Acuras, besides this Car we currently own a 2017 MDX Advance. This car seems to have a problem with the door lock or the custom settings. When set in lock at speed the doors make a locking sound every time I start for a stop. The rear door on the drivers side will not lock at all, not with the key fob or the button on the door or manually. When I try to lock the car from the outside it doesn't beep or flash the lights even though I have it set to do so. Other than that the car is fine , it only has a little over 25,000 miles and runs great. Any suggestion as to what is causing this problem?
