ESC Light Issue in Mercedes-Benz Vehicles

The Electronic Stability Control (ESC) system in Mercedes-Benz vehicles, such as the 2010 GLK 350, helps maintain stability and course control, especially during sudden maneuvers. If the ESC light is on, it may indicate a problem with the clock spring or Steering Angle Sensor (SAS), or an alignment issue, particularly if the vehicle pulls to one side.

Recent repairs, like new shocks and struts or steering wheel removal, can also affect the ESC system. A DIY steering angle calibration or an OBD-II reader can be used to check for error codes and determine the cause. The National Highway Traffic Safety Administration (NHTSA) recommends addressing ESC issues to ensure safety on the road.

According to Mercedes-Benz, the ESC system is an essential safety feature, and any issues should be inspected and diagnosed by a qualified technician to ensure proper repair and maintenance.
