What stands out
No new NHTSA electrical complaint has been filed on this vehicle in over 11 years — the issue may be aging out of the active population.
The failure pattern owners describe
Buyer takeaway: Multiple owners report underhood electrical fires—some while driving, others while parked—that Hyundai has issued recalls for but not reliably fixed. Additional electrical gremlins (failed starters, dead lights/windows, weak horns, static shocks) suggest systemic wiring and power distribution problems across this model year.
Electrical fires dominate this complaint cluster. Two owners report flames erupting under the hood during operation—one driver experienced a loud bang, power loss, and smoke on a highway before the vehicle fully ignited and was totaled. Another fire happened while the vehicle sat parked in a driveway untouched for over 28 hours, occurring ten days after the dealer performed brake work.
Hyundai issued Recall 251 (NHTSA #23V651000) for electrical fire risk, but owners report the recall remedy remains incomplete or unaddressed months after notification. One owner was promised a rental to avoid parking the vehicle near structures and received none; another states the repair had not been done as of registration check.
Beyond fires, owners report widespread electrical dysfunction: engine cranks then freezes and won't start; headlights, windows, and remote unlock fail simultaneously then work again the next day; horn produces dangerously weak sound inaudible at highway speeds; key fob causes alarm to engage without intent; electric shock occurs when touching doors. One owner reports rodents chewed through soy-based wire insulation at under 15,000 miles, and Hyundai initially promised reimbursement, then refused. A dealer was unable to diagnose the static shock problem.
