Known issues on the 2021 XT6. Two recalls are on federal record for this model year. The first covers the fuel supply lines, which may be improperly attached and seated, potentially loosening or separating and causing a fuel leak with an increased risk of fire. The second covers the rearview camera on vehicles equipped with the optional Surround Vision feature: coaxial cable connectors that were crimped improperly can cause the camera to fail or function intermittently, reducing the driver's rear visibility. Owners have filed 18 complaints for the year, and no technical service bulletins are logged. The factory diagnostic and repair procedures behind each of those systems are here.
From tracing a fuel-line leak to troubleshooting a dropped rearview camera feed, it keeps you on the OEM procedure and the correct specification for your specific 2021 XT6.
