obrother, good news that Mitsubishi is honoring your warranty! I'm interested in knowing the steps you finally went through. Tend to agree with kiev that the 12v battery is the first thing to check. Look at it this way, after all is said and done, you now have an electric car with a brand-new battery. When you get your i-MiEV home, do measure the battery capacity and let us know what it is - you might record that number and then check again after you've done a full recharge from below two bars, as the system will probably recalibrate.
