The automatic engine start-stop system, designed to save fuel, has been reported to occasionally cause delays o r failures, such as hesitation in restarting o r increased battery drain. In Pakistan’s stop-and-go traffic and hot weather, these problems might be more noticeable. Some owners also report sensor o r battery-related issues affecting the system’s smooth operation. Hyundai dealerships recommend regular battery health checks and software updates to improve start-stop system reliability.
