2014 Hyundai Elantra

Engine complaints dominate the 2014 Elantra's complaint record, with owners frequently describing internal engine failures, often with little or no warning beforehand. A recurring pattern involves cylinder wall damage found during inspection, sometimes triggered by a knock sensor fault code, and owners report these failures occurring at relatively modest mileage with otherwise routine maintenance histories. Several complaints describe engine fires starting in a parked, switched-off vehicle, with no prior warning lights or symptoms. Brake complaints are the second most-reported area, where owners describe issues ranging from the parking brake not holding reliably to brake lights failing to function even after bulb replacement. A smaller cluster of electrical complaints rounds out the picture. The engine failure pattern, particularly cylinder scoring paired with a knock sensor alert, appears consistently enough across multiple reports to stand out as the clearest theme for this model year.
