Honda Civic Hybrid Problem

Visitor, 2007 Honda Civic Hybrid, 53,000 mi
I have a Honda Civic 2007 (not hybrid). I just moved from Florida to Denver and started having this problem (hard brake when I first start the car but fine after that), so it makes sense that it's related to altitude. Taking it to a shop today to see how much it will cost to fix.
