Air bag error light was on and caused by setting iPhone on front passenger seat per GM bulliten.
DVD player worked intermittently. Would play some dvds but not others. Dealer replaced DVD Nav system. Everything works fine now.
After may trip to dealer for servicing, the low tire indicator would not identify the correct tire. It seems they failed to reset it properly after rotating the tires.
From time to time heater would stay or come on during hot weather and could not be turned off. "Control Head" replaced.
So far so good.
It seems the connector for the cooling fan lost contact and the coolant overheated and was released thru' the safety valve. System was recharged and is now cooling, but still turning on and off. Another vist is likely required. Update: just unplugged.
A/C blower making noise. Remove and replaced A/C Blower assembly.
Door latch not registering door open/closed, so not turning off stereo on vehicle exit, or turning on interior lights on door open.
Several occasions- "Service Park Assist" message on dash. Quick software update corrected issue.
Park Assists Always worked though.
