2006 Buick Terraza 6 cyl Front Wheel Drive Automatic 65000 miles
For reasons we cannot determine, our Terraza will randomly give us a " beep-beep" after we enter the car and close all the doors; and just as randomly as we are going down the road. This " beep-beep" (always 2 beeps) comes and goes; with days or weeks in between occurrences.
It's making us crazy! Can you help identify the source?
