2005 Hybrid with recurrent engine/IMA lights

This is driving me to the poorhouse!:shakehead

I have a 2005 Honda Civic Hybrid with about 120,000 on the clock. For the last several months, I've had a recurrent problem with the "Check Engine" and the "IMA" lights coming on, either together or one at a time.

So far, I've had the catalytic converter, the plugs, the air filters and the sensors replaced. It keeps happening anyway. The mileage drops off from the mid 40's to the mid-upper 30's when these lights go on. I must have dropped $1,500 in this car for this problem since it started. :eek7:

The trouble codes are the same as the last several times.

Anyone have any ideas on what is causing this? I'm tired of taking taking it back to Honda. :disappoin

Contacted a Honda mechanic offline who tells me that it's probably a secondary O2 sensor and the main battery pack. I am not amused. That's a $3K bill all by itself and I bought the car as a Honda Certified Used Car. I'm still paying for it.

If he's right and we can't work out something with the dealer, this will be the last Honda I buy.
