Service 4WD
#4
Re:Avalanche
My 2006 5.7 limited 4WD was in the shop 22 times during the warranty period - mostly for the service 4WD message. The fixes included a pigtail on the rear differential as the original wiring was too short, new sensors front and rear, a new sensor/control of some sort they had to pull the console to get at from the top, and several flash attempts. The dealer finally got it I think - 6K...
