The failure pattern owners describe
Owners of the 2015 Kia Sportage describe a range of electrical and engine failures, with fire the most serious recurring complaint. Several owners report the vehicle catching fire—either while driving or parked—preceded by burning smells, electrical system lockups, and smoke. One fire occurred in the rear near a newly installed trailer hitch involving the wiring harness "black box"; another happened at 2,000 miles with total loss of power steering and braking. Two additional owners report engine fires during highway driving.
Beyond fires, owners report persistent engine knocking (sometimes relating to HECU failure per Recall 22V051), chronic stalling at idle and highway speeds, and intermittent no-start conditions despite battery and fob replacement. Electrical gremlins include infotainment screens that won't shut off and drain the battery, USB and radio failures, false ignition warnings, and complete dashboard light shutdowns after water exposure followed by burning wire smells.
Dealership response is inconsistent: some can't replicate issues despite multiple visits; others refuse warranty claims once mileage exceeds 100,000 miles, even for safety recalls. One owner reports the vehicle parked in a medical center parking lot caught fire unattended, totaling the car. Owners express fear of driving and question whether repairs genuinely fix the problem, citing news coverage of post-repair fires in other Kia vehicles.
