I have a 2012 Hyundai Sonata Hybrid, warning light came on that said Hybrid battery low stop do not drive. So I replaced the battery and nothing... my car is completely DEAD... had towed to dealership and they said it's the power relay assembly kit. I am lot having them replace and fix because they want over 1,000.00... does anyone have any idea if this is really what is wrong???


It is the switch inhibitor. I had the same problem a year ago on my wife's 2013 sonata. It's a common issue with this model. It's a 30 dollar part from the dealer. Relatively simple part to switch out yourself. You'll need to pull out the intake manifold, battery, and the platform the battery sits on in order to access it.
