Known issues on the 2020 XT6. Four recalls are on federal record for this model year. The first covers the fuel pump, where a manufacturing burr can block the jet nozzle and starve the engine of fuel, causing a stall without warning. The second covers the roof-rail curtain air bag inflator, whose diffuser may not be properly crimped and can separate during deployment, degrading protection in a crash. The third covers the automatic transmission's start-stop accumulator endcap, which may ship with missing bolts and can leak transmission fluid, in the worst case leading to a loss of propulsion or a fire near an ignition source. The fourth covers the rearview camera, where improperly crimped coaxial cable connectors can cause the camera to fail or work intermittently, cutting into rear visibility. Owners have filed 36 complaints for the year. The factory diagnostic and repair procedures behind each of those systems are here.

Whether you're tracing a fuel delivery fault, inspecting the roof-rail air bag system, or servicing the start-stop transmission accumulator, this manual keeps you on the OEM procedure and correct specification for your 2020 XT6.
