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. Im in a cadillac group and hundreds of us have similar issues.
