Engine Recalls

Large-8119-2014Sonata

In close coordination with the National Highway Traffic Safety Administration (NHTSA), Hyundai has conducted several recalls to address manufacturing issues that could lead to engine failure and in certain circumstances an engine fire. While the majority of incidents among affected vehicles are limited to engine knocking, there have been instances of stalling, meaning the engine may stop running while the vehicle is being driven. Importantly, drivers in this situation can maintain control of the vehicle as brakes, steering and safety devices like airbags remain operational.

Typically, as an engine becomes inoperable, drivers will be alerted by warning lights and sounds, and while the engine may experience some hesitation, drivers should have time to safely move the vehicle off the road.

Engine Oil Pressure

  • A knocking noise from the engine that increases in frequency as the engine rpm increases.
  • Reduced power and/or hesitation and vibration.
  • Illumination of the “check engine” light in the instrument cluster.
  • Illumination of the “engine oil pressure” warning lamp.

Technical Overview

Among the affected vehicle population, vehicle stalling may be triggered by premature engine bearing wear. Indications of a worn bearing are outlined above. If the vehicle continues to be driven with a worn bearing, the bearing can fail, and the vehicle could stall. In some instances, engine stalling can lead to the fracture of a connecting rod. When a connecting rod fractures, it is possible for it to damage the engine block, allowing oil to escape and contact hot engine surfaces, which can lead to a fire.
