Service campaign N252528241-01

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Certain vehicles listed above may have a condition in which the vehicle experiences a reduction in deceleration during a low-speed ABS braking event when the road surface transitions from smooth to rough surfaces. Dealers are to reprogram the Brake System Control Module. Owners who have accepted applicable terms and conditions will have the opportunity to accept these software changes using wireless over-the-air (OTA) technology without having to bring their vehicle to a dealership. Alternatively, owners may have their vehicle serviced at a GM dealer to receive these software updates.
