I've had my Acadia for almost a month now. The children and I have noticed that the rear (think second seat) controls for A/C, Heat and fan etc. sometimes get quite warm to the touch (not enough to burn, but enough to wonder if it is an issue). This does not happen on any of the controls on the dash or on the doors. It seems to only happen at night, but again, those controls up front remain cold to the touch. Have yet to ask the dealer about it, but wanted to find out if anyone else was experiencing this.
