Went to the closest dealer for my first complimentary service. It was not the same dealer I purchased from and will be the last time I go there. On the way home the car was providing a harsher ride than normal. I checked the tire pressure and all were at 39-41 psi. Pulled off at next exit, found a gas station and let some air out of all tires. Got them all to about 36 and headed home. Checked the worksheet I was provided and it indicated they filled tires 36 front and 38 rear (while still warm!) as per specs. Called the service department when I got home to ask why. Service manager said sticker in door is generic and is only for safety compliance (WTF) and then instructed me to check the PCM for the correct pressure for the size and type of tire on the car because that's what they rely on. Ok, checked that and it recommended 30 rear, 29 front for the 19 inch summer tire just as the door sticker indicates. Tire pressure requires basic knowledge and the fact they did not know and got it wrong for all the wrong reasons would make me cautious to go back there for something more complicated. I'll adjust pressures tomorrow when they are cold. Oil level was a little low but still in the correct range. Anyone in central-Florida area wanting details can pm me.
