2017 Cadillac CT6 Complaints

  • Suspension, power Train, wheels 05/14/2026

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

  • Power Train, vehicle Speed Control 06/15/2018

    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.

  • Fuel/propulsion System 10/07/2025

    My CT6 had a default engine light on,.Dealer reports broken EVAP line.Car has never been in an accident or damaged.Upon inquiry dealer reports no issues known to them with this problem.However ,this same vehicle had transmission issue when purchased new and the dealer stated same findings.Then recall was issued and transmission was repaired for a known problem and repaired under a recall notice.My concern is this may be similar situation with the fuel EVAP system.The vehicle is my primary car and a fuel vapor leak is a grave concern to me and I believe posses a risk, especially as the replacement parts are unavailable at this time.I have filed an inquiry with Cadillac/Gm #82543696 Steven Maffei(AI inquiry reveals known and past problems with Cadillac EVAP systems)

  • Vehicle Speed Control 04/02/2025

    My vehicles transmission has a buzzing noise coming from the transmission oil pan and a gear shifting problem I took vehicle to Cadillac dealer whom can’t find the issue they changed the oil pan and the transmission lines . My vehicle is a 2017 Cadillac ct6 with 72027 miles . I’ve been to 4 Cadillac certified dealers and none can locate to problem . Thank you . Also I would like to add that Cadillac open road In New Jersey has taken off my splash guards and would not return them . I have a video of the manager claiming the car doesn’t come with guards and another stating the job he did not require him to remove splash guard but that is not true .

  • Electrical System, structure 02/12/2025

    Water is getting into my trunk where the amp is and now my radio does not work only the back up camera. I cannot control the AC or turn on the air conditioner. Or is that how I would like it to blow
