Powertrain complaints dominate owner reports for the 2016 CT6. Owners most often describe transmission-related symptoms: rough or abrupt shifting when moving from park into reverse or drive, unexpected jolts during gear changes at low to moderate speeds, and general drivability issues including persistent shaking. A few owners also report fluid leaking from underneath the vehicle while parked. On the engine side, a small number of reports describe recurring power or boost problems, with at least one owner noting that cylinder-specific issues returned after a repair attempt. Two airbag complaints exist in the data, including one involving non-deployment during a collision, but with only two reports, this cannot be characterized as a pattern. The transmission shifting and drivability concerns are what show up consistently across multiple owner accounts.
