A Hyundai Dealer Dumped This $400 Sonata Hybrid at Auction — Their $8,000 Fix Was Wrong

A 2013 Hyundai Sonata Hybrid showed up at auction — sent there by the Hyundai dealership themselves because they didn't want to deal with it. Their diagnosis? It needs a new hybrid battery pack. Their quote? $8,000. So they dumped it at auction instead of fixing it. I bought it for $400. Monkey Wrench Mike and I got to work diagnosing this thing ourselves. We checked the battery pack, the modules, and the relay. The dealer was wrong — this car doesn't need an $8,000 hybrid battery pack. We found the real problem and ordered a $150 part from eBay to fix it. Did the $150 eBay part work? Not quite. After further diagnosis we determined the real culprit is the BMS — the Battery Management System — which is now on order. The dealership gave up on this car for $8,000. We're not giving up for a fraction of that. Stay tuned for Part 2. 🔧 Check out Monkey Wrench Mike: https://www.youtube.com/@MonkeyWrenchMike 🛍️ Auto Auction Rebuilds Merch: https://randy-shear-shop.fourthwall.com/collections/all 🚗 Find the true history of your car here (with pics): https://tinyurl.com/y3xx7rjv 💰 Get your $5.99 CarFax or AutoCheck here: http://www.autovhr.com/deal ⚡ Get up to $2,500 off a new Tesla: https://ts.la/randy96972 📘 Follow on Facebook: https://www.facebook.com/autoauctionrebuilds/ 📸 Follow on Instagram: https://www.instagram.com/autoauctionrebuilds/ 📧 Email: [email protected] #HyundaiSonata #HybridBattery #AutoAuctionRebuilds
