2013 Chevrolet Sonic
At the end of last week, Chevrolet posted an official recall notice for all 2013 Sonic cars after it discovered a fault in the system responsible for detecting a blown turn signal bulb.
Under normal operation, the unit, called the Body Control Module (BCM) should detect when a turn signal lamp has broken, alerting the driver so it can be repaired.
However, during regular internal tests, GM engineers discovered that the ‘signal bulb outage detection’ feature was disabled on the BCM unit fitted to all 2013 Sonics.
With that particular feature disabled, the car will not alert the driver should a turn signal bulb fail, meaning owners may use their turn signals unaware that their intentions can not be seen by other road users, increasing the risk of a crash.
GM has said it will recall all 4,716 affected 2013 Sonics starting October 3.
It will then reprogram the faulty BCM units and the key fobs of each car free of charge.
Meanwhile, concerned Sonic owners can contact Chevrolet owner center at 1-866-694-6546 or visit their local Chevrolet dealer.
No other Chevrolet cars are affected by this issue.
