I finally took in our 2016 Buick Enclave because for the last two winters once the temperature got below zero the power liftgate would not work, I had to open and close it manually. I found out today that there is a bulletin out form GM that the liftgate is only designed to work between zero and 120 or 130 degrees. What the hell kind of design is this. So do they tell everyone who is buying a GM that the power lift gate will not work if the temperature is below zero???? For a $50k vehicle this seems like BS, actually it would be BS if it was any vehicle. I have always been a GM man but I have to say this is really a poor design. We live in Wisconsin and to know power accessories on the vehicle may not work if it below zero is ridiculous. They shouldn't sell these in clod weather climates.
