UNKNOWN, The transmission slips,it wont drive now and my wheel barrings nearly snapped

2017 CADILLAC CT6

Filed Jan 29, 2026


The vehicle experiences harsh shifting, surging, and jerking forward during normal driving conditions. The behavior has occurred repeatedly over several years and has been confirmed by the dealership. Multiple repair attempts, including transmission-related work, have not resolved the issue. The vehicle has surged forward unexpectedly, creating near-miss accident situations. I no longer feel the vehicle is safe to operate.
