Constant AC fan noise
Since new, my EX has had a fluttering noise that increases as the fan is turned up. The dealer kept it awhile to put another new Insight next to it and found they both are noisy. the tech admitted there was another Insight that had the same problem. No remedy until the company acknowledges the problem and allows a recall or fix of some sort. If there is anyone else with this issue, please call American Honda at 800-999-1009 to get them to address the problem.
As for mileage, at 9k, I've meeting consistently getting only 44-46mpg, very disappointing, no matter how good a hybrid driver I am.
