why should a brand new car have to turn off the a/c unit during trip thru mountains?
during recent trip from Phoenix to Las Vegas, the car I was in a 2014 escape 1.6 ecoboost, a light came on instructing the driver to turn off a/c . the temp outside was about 110 . the car is about 4 months old. the road was hilly but not severe hills. is this common?
