HYUNDAI i30 (2010–2012)
What the hazard is
In the event of ESC malfunction, the ESC system will not be able to stabilize the vehicle when it is out of control. The ESC system is part of the ABS system and the ESC malfunction will prevent the vehicle from stopping at its optimum designed capability. This malfunction would increase the risk of a vehicle crashing in the event of emergency braking or if the vehicle were out of control.
What to do
Return the vehicle to an authorised Hyundai dealership to have the ESC module replaced. Owners of affected vehicle will be notified by letter.
Defect
There is a risk of the ESC electronic control case being damaged in the process of assembly. The damage will result in a crack on the casing that may let moisture into the electronic components, which could lead to short circuit and ESC malfunction. If the defect occurs, a warning light will show on the dashboard and ESC function will disengage.
