Well the new shutter system solved our problems. Car made the journey back to Central California with no overheating message even over the three large passes you have to drive over. As a side note, the A/C works really well again.

So it appears that the dealer here in Glendale AZ might have found the issue related to our problem with high coolant temp. They found what remains of either a mouse/rat or bird carcus inside the shutter system preventing it from opening. This would cut off air flow through the radiator. I am glad that they at least looked at the issue differently than the other two time we took it in to the dealer in CA. Will report back after we get the car back and test it on the highway going up a grade. brad

THanks for the reply. Last week when the family drove out there from the Central Coast, the car got hot on all four passes/hills getting down there. The car still has power but we have to drop the rpms and off with the a/c till it starts to go downhill to the flat area, then the temp gauge goes back to the middle. Going to give a dealer in AZ a chance to fix it or I will just get rid of the car when I get there next week. It’s a shame because aside from this problem, it is a fantastic car, I just don’t trust the car, especially when my daughter needs to drive back for school in another month. The dealer we have brought it to in CA two times for this issue said they couldn’t duplicate the problem. I guess that means it must not exist? Maybe i have been dealing with a crappy service dept? I really don’t want to deal with this anymore.

Did you ever get this resolved? I have the same exact problem with my 2015. Only going uphills with ac on. We have had to turn off ac and turn up heater to resolve issue until we get to the top of hill and can coast. Weird only on uphills when the temp is above 88 or so degrees. Our dealer said they tested the fans, coolent level and for leaks, all came back as normal? Problem just popped up when we moved to Az last week. Dont really know what to do since they cannot duplicate the issue, then it must be fine? Any luck?
