Finally got my rear window replaced on 2/21/20, we'll see how long it stays dry. Dealership I have been dealing with is a HUGE dealer with extremely subpar service consultants! Wasn't contacted when window arrived, had to stop by and learn it had been there for weeks. Dropped truck off and was taken great care of and request for a service loaner was quickly fulfilled. Was told it would be at least a day possibly day and a half as they had to do the oil lines, recalls, and window. Next day I waited until 1500 to call and check on truck and was told my service adviser was gone today but appears my truck was done in the AM and no one called. Picked up truck and noticed muddy footprints on back seat headrest, all over the back of my front passenger seat and console, and all over the floor. I understand the floor but damn, could they not look over the truck and put 5 minutes of effort to clean it and make the customer feel they care? When I walked up to the service consultant he looked at me, picked up his things, and then proceeded to leave for the day without saying a word to me. GREAT CUSTOMER SERVICE! Speaking of service, the oil lines were also replaced which the recall states is to be done with an oil change and new filter. Checked the oil level and it was barely on the dipstick. Spoke to the service manager who said "Warranty work only pays for 8 qts of oil". Really, as a huge dealership your only going to put the minimal amount of oil versus filling it. Absolutely amazes me how poorly GM treats the customer. Hopefully the window remains leak free.
