My 2000 insight with 110k miles has been flawless the last few years but today I woke up with no regen brakes or assit and a engine light and a IMA light on. The IMA shows almost a full charge. The car starts and runs fine aside from less acceleration due to no assist. Honda dealer says code P1449 means IMA battery needs replacing, IMA motor control module and IMA motor control module all need replacing. Estimate $5,436.91 I don't understand how this could all just happen at once. I bought the car a few years back with 60k miles and a recently updated factory battery pack. Fuel mileage is averaging 49 which is only down a bit from before. Anybody with suggestions?
