The Hyundai Dealer Said $5,000 — I Fixed It for $75

I picked up this 2014 Hyundai Sonata Hybrid Limited from a Hyundai dealer with 119,000 miles. Their diagnosis? A bad hybrid battery — over $5,000 to fix. I wasn't buying it. In my last video we pulled the hybrid battery and tested every single cell — they all came back good. The real culprit was a failed BMS module. In this video I install a $75 eBay replacement BMS, reinstall the hybrid battery, and fire this thing up for the first time. Then I take it out on the highway for 10 miles to prove it out. Total investment in this car: $525. Dealers don't want you to know this.
