This is a warning to anyone looking to buy one of these vehicles. I just bought one a couple months ago and it makes a constant loud annoying humming sound around 80 mph. The sound actually starts at 70 and continually gets higher in pitch and louder up to 80 mpg. Honda refuses to do anything about this problem, they state that since the condition occurs outside the legal speed limit for my state, they are not obligated to fix the problem. So if you looking at buying the Hybrid, beware. Buying a car from Honda in general may not be the best idea if their policy is to refuse repair for conditions that only occur at higher than the posted speed limit. As for me, I will not be buying another Honda, nor will anyone in my family. There customer service for this issue has been pitiful and a bitter disappointment.
