Hi, I am very seriously looking at buying a phev to replace my current car. I have read most of this forum to see what problems, if any, people are having. I am looking at getting a used phev with around 30000 miles. I am concerned about the battery and how long it would last so was pleased to see a 8 year 100000 miles guarantee available. But having read this link I am confused about if this guarantee covers pre update (Sep/Oct 2015). If earlier cars are covered the phev would be more in my price range.can someone please clear up my confusion. Thanks.
