Known issues on the 2016 CT6. Three recalls are on federal record for this model year. The first covers the rear seat assembly, where the inboard child-seat anchorage bars may carry excess structural adhesive that interferes with correctly attaching a child seat. The second covers the front seat belts, where a missing bolt at the seat anchor can let the webbing detach and fail to restrain the front passenger in a crash. The third covers the exterior lighting, where the park/position lights may run excessively bright and affect other drivers' vision, raising crash risk. Owners have filed 11 complaints for the year. The factory diagnostic and repair procedures behind each of those systems are here.
Whether you're tracing a seat belt anchor, checking a child seat mount, or servicing one of the three engine options, it keeps you on the OEM procedure and the correct specification for your specific 2016 CT6.
