The demonstrator I drove didn’t squeal and the cynical part of me thinks they clean the brakes on these cars often. When I first complained about it the dealer said there wasn’t anything they could do as the brakes are “ a bit hard on this model” but they had given them a good clean. Driving home there was no noise but it returned after 100 miles or so.
There is some travel on my brakes but I was ready for this as it’s mentioned in almost every review. However, there is no issue with stopping power and it’s something you get used to very quickly - a bit like when a new clutch bites.
