have a 2007 civic hybrid with 85k miles bought new and live in a hilly area. Bought a new Prius and getting ready to sell the civic when I noticed IMA issues on the dash volt meter. When it sat for a couple of days, guage showed 2-3 bars then green charge for maybe a mile and wham full guage then after couple of miles down to half or so ..few more miles down to 1-2 bars with charging and never get back to a full charge. So at this point think battery is going bad? No error codes or IMA light just erattic guage. Any ideas??? Of course here in Oregon warrenty is 8yrs or 80k miles
