Known issues on the 2005 Avalanche 1500. Three recalls are recorded for the year. One involves the shift lever position indicator, which under certain starting conditions can show something other than the gear actually selected, so the truck may move in a direction the driver did not intend. Another describes the hydraulic brake booster's pressure accumulator cracking and separating from its assembly during normal use. The third concerns second-row center belt routing that lets the lap belt ride up onto the abdomen. Electrical complaints lead the year's 206 at 68, with the power train at 24.
