Known issues on the 2017 Yukon. Three recalls are on the federal record. One covers a vacuum pump whose output falls off with use, cutting brake assist and lengthening stopping distances. Another describes a wheel-speed sensor failure that trips the driveline protection system, which then brakes the opposite wheel and pulls the truck sideways without warning. The third concerns frontal air bags and belt pretensioners that may not deploy in a crash calling for them. Complaints total 196, with 45 on the power train, 44 on exterior lighting and 30 on the brakes, all covered by the diagnostics here.
