Been taking my 2011 GMC I bought used a couple years ago to a dealer for service (oil changes, tire rotations). That dealership has numerous times failed to lube, top off fluids and even rotate the tires when required, even after I politely mention such things. So I took the truck to another GM dealership this evening for service. A-arms again were not lubed (service advisor even highlighted it on the write up) and tech wrote on the summary all points lubed. Makes me wonder if they actually perform the rest of the services they claim (and charge for). Is this how all dealerships are running their service departments these days? Only reason I take the truck in is because there is still a warranty on the truck, figured if anything were to go wrong I have proof a GM dealer has performed all work on the truck and they'd have a tougher time not honoring the warranty. I may have to go back to doing the work myself.
