The failure pattern owners describe
Buyer takeaway: This model has genuine electrical system problems that dealerships struggle to diagnose and repair. Battery drain, junction box faults, and control system failures can leave you stranded or unsafe, with some cases dragging on for months without resolution.
Owners report a range of electrical problems in 2022 Hyundai Sonatas, with battery drain and electrical system faults dominating the complaints. Several owners describe dead or deeply discharged 12V batteries after only three to five days of non-use, persisting even after the battery itself was replaced under warranty. One owner reports the vehicle shut down completely while driving multiple times, creating a safety hazard; another experienced total power loss stranding them out of state.
Door control and mirror electrical faults appear in multiple reports. One owner describes the driver-side door panel buttons intermittently unresponsive with flickering lights, accompanied by side mirrors moving randomly during driving. Another reports inability to lock the car, operate signal lights, open the fuel door, or unlock the trunk—traced by the dealer to the junction box, a component that was recalled in earlier Sonata model years.
Infotainment and safety system malfunctions are also cited. Owners report voice command failures affecting navigation and messaging; one owner received 15 stored diagnostic trouble codes involving Lane Keep Assist, Electronic Stability Control, Smart Cruise Control, and tire pressure monitoring—some appearing before purchase or within 1,000 miles. Another reports the blower fan failed without warning.
One owner had their vehicle kept at a dealership for 90 days with multiple unresolved recalls; Hyundai approved a buyback but has not completed it. Dealerships generally report inability to diagnose or reproduce faults during test drives.
