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.

Electrical System · reported Nov 21, 2024
These vehicles have an issue tbat GM is aware of, with their 8 speed automatic transmissions which are used in multiple GM vehicles and these cause safety issues because for instance my vehicle switches gears randomly almost causing a wreck, and shuttering, and even slipping and when this happens the cars traction control light is engaged shutting it off, active steering is also shut off due to these on going issues.
