Hyundai Elantra engine shuts off while driving on the highway on Hyundai Elantra

Some Hyundai Elantra owners report experiencing engine shutdowns while driving on the highway, which can pose serious safety risks. Common causes include fuel system issues, such as a faulty fuel pump or a clogged fuel filter that restricts fuel flow, leading to engine stalling. Additionally, electrical problems like failing sensors or wiring harness issues may result in unexpected engine shutoffs. Some owners also note that dirty oil can clog CVVT solenoids, causing timing problems that lead to engine shutdowns, particularly during deceleration. Other reported symptoms include warning lights on the dashboard, difficulty restarting the engine, unusual noises or vibrations, and decreased engine performance. It is crucial for owners facing these issues to seek prompt assistance from a qualified mechanic or Hyundai service center to ensure their safety and the vehicle's proper functioning.
