The recall only affects those 2012 Buick Regals built from February 22, 2011, through February 22, 2012.
There are some 3,633 units thought to be in existence in the U.S. alone.
The issue stems from a software error affecting the parking light units in the Regal’s headlights. In certain cases, the parking light units fail to activate when either the parking light or headlight function are switched on.
The consequence is that inadequate lighting may reduce the visibility of the driver, thus increasing the risk of a crash.
Owners of the affected vehicles should take their cars to their nearest Buick dealer, which will reprogram the body control module free of charge.
