I purchased a 2017 Pacifica Limited just after Thanksgiving and I have the identical problem you are experiencing.
All I do is touch the Driver Temp Control Up or Down button and the temp will go to one degree up or down (depending on which button I press) from my normally set AUTO & SYNC Temp which is 70 degrees. As soon as I do this, everything resets to normal ops. If I don't use remote start, I start the vehicle and both sides and rear are at 70 degrees.
By coincidence, I just called the dealer and they advised that they had not heard of this issue.
This ONLY happens with remote start.
I have tried resetting the position 1 & 2 memories and remote transmitters, but no change. I will have the dealer look at this at some point.
The only other issues I've had is one occurrence where I could not change SXM channels from the touch screen and the steering wheel. I stopped the car, turned off the engine, locked the car, then unlocked and restarted and all normal. Again, only one time.
The other issue which happened yesterday for the first time; I selected Media to listen to music on my iPhone and it displayed iPhone Unknown. I went into settings, selected my wife's phone, then back to mine and all normal.
Other than these issues, I could not be more impressed or happy with this purchase thus far.
