The failure pattern owners describe
Owners of 2010 Hyundai Elantras report widespread electrical problems across multiple systems. The most severe involve spontaneous vehicle fires occurring while parked—several narratives describe fires that started in the engine compartment, with fire departments concluding electrical origin. One fire occurred after only 6 months of ownership; another happened within 15 minutes of parking. Owners report losing complete vehicle control during driving, including failed brakes, unresponsive steering, doors that won't unlock, and vehicles that will not stop or shift out of park.
Battery drain issues are common, with owners unable to start vehicles after overnight parking despite new batteries and successful alternator diagnostics. The alarm system activates randomly without triggering input, sometimes correlating with direct sunlight. Key fob functions fail intermittently. Door locks and window regulators stop responding to central switches, though manual switches sometimes work. Warning lights illuminate unexpectedly—airbag, ABS, service engine, TPMS—and remain on despite dealer visits. One owner reports the ignition key itself becomes hot and won't turn even after cylinder replacement. Accessory sockets (12V outlets) cause TPMS light illumination. One narrative describes visible wire damage with melted interior plastic and burning smells before fire occurred.
