IMA maintenance excluding the battery? - Honda CRZ Forum: Honda CR-Z Hybrid Car Forums

So I've been wondering what kind of maintenance there is for the IMA motor and such. Maybe the electric engine needs to be cleaned out, oiled, ect? I can't really find much on the topic with any Honda IMA car.

Nothing. Just let it ride. Your 12v battery will eventually start giving up and the symptoms will vary. Often times people think it's something else in the IMA system. The IMA system is good and lasts a very long time.

So 100% no maintenance on the hybrid system (minus battery) itself? That seems too easy; it has moving parts. I can't see an IMA system with 300 miles (gunk in the motor, grease dissolved, ect) being as efficient as a new system, let alone any preventive maintenance.

It has the same number of moving parts as a flywheel. Think of it as a magnetic flywheel. Sometimes it's used as a motor, sometimes used as a generator.

If you get 300,000 miles on it, and if you have the engine and tranny out and separated, you could probably clean it up and improve efficiency a little. It's not on the maintenance schedule though.

Keep it sealed and keep it happy.
