Schepel Buick? I thought I was at Schepel Cadillac. Anyway, something went wrong with one of my rear bumper safety sensors on my 2015 Cadillac SRX. It took two visits to diagnose and repair the faulty sensor. The replacement part was in stock on the first visit, but it needed to be painted to match the bumper color. The second visit was to install the new painted sensor. Thanks to the great GM warranty, there was no cost to me. I am a loyal GM customer, but I sure do miss Pontiac.
