Certain pickup trucks may experience the permanent loss of brake lamp function or brake lamps that are illuminated at all times. The center high-mounted stop lamp (chmsl) is affected in both instances. Also, if equipped, the cruise control will become inoperative. Any trailer brake lamps which are connected to the vehicle's brake lamp wiring will mimic the vehicle's brake lamps when either condition occurs.
Dealers will replace the brake lamp switch assembly. The recall began on December 5, 2006. Owners may contact Chevrolet at 1-800-630-2438; GMC at 1-866-996-9463 or Isuzu at 1-800-255-6727.
