Honda Accord Hybrid that dies

Our 2005 Accord Hybrid just dies now and then but always re-starts immediately. The dealer said the IMA battery overheated because we had to much stuff packed in the trunk. Anybody else have this problem?

What good is the trunk then?

I don’t know what a IMA is, but the trunk connection sure sounds wacky.

IMA stands for Integrated Motor Assist - the electric motor side of a hybrid.
