My hybrid battery has been slowly degrading. Now at 120k miles, it still works a little, but I only get maybe 34 mpg and the engine/IMA lights come on randomly. I would take it to the dealer but the lights don't stay on very long and besides I don't want to pay$$ for a new battery now. But here's the problem: lately I noticed a smell like hot glue melting whenever the IMA light comes on. Is my battery getting ready to catch fire??

 

What state was the 2007 Civic Hybrid purchased in?

 

Batteries in hybrids have a 10 year warranty I though? 7 maybe?

 

The warranty was 80k miles so that's all done with. Purchesed in MD so no protections.
