No problems for me that you have described although not driven it at 70 much and in 6 weeks only done 600 miles lol. Hill start is really smooth for me, I am shocked at how good it is.
Enjoying the car with no real issues so far. It's the most fun car I have had for many years and I love driving it, so much better than our 14 plate yaris whihc I now hate to drive.
