It is not normal for the Sonata's temperature gauge to fluctuate. The temperature gauge displays the coolant temperature of the vehicle, helping the owner understand the car's condition. When the engine temperature is too high, the owner should stop the car and wait for the temperature to drop to a normal level before continuing to drive. The Sonata is a mid-size car under Hyundai, a South Korean automaker. In terms of body dimensions, it measures 4747mm in length, 1820mm in width, and 1440mm in height. In terms of power, the Sonata offers two engine options: a 2.0L inline-4 and a 2.7L V6. The 2.0L inline-4 engine belongs to Hyundai's B-series engines, capable of producing 137 horsepower and 180 Nm of torque, paired with a 4-speed automatic transmission.
