2017 Cadillac CT6 Problems, complaints & recalls

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

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.

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...

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 .

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

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.

Transmission - Jerks and studders (hesitation) in the course of normal driving. Brakes - Makes a squealing noise which has gotten louder over time.

The car is equipped with an 8-Speed Automatic Transmission which is frequently very hard shifting from 1st to 2nd gear. The car has been to my local Cadillac Dealer twice for this problem; they reply this is a know problem, and a normal condition, but the problem is getting worse. I'm concerned for the future and afraid of an accident because of a transmission failure.

SIDEWALL CRACKING ISSUE WITH ALL FOR TIRES - PIRELLI P ZERO NERO 245/40/R20 While traveling out of town (Dallas to San Antonio) we experienced some tire issues which led to us needing to replace all 4 tires. Several weeks prior, we began to noticed a very slight loss of tire pressure and had the tires checked twice for any objects or other damage - Nothing found. We also had the tires rotated to trouble shoot and rule out any issues with sensors - none. Both times, the service shops did not mention or...

I was driving the vehicle heading to the interstate, and my speed was about 15 MPH, as I merge onto the highway and accelerated I felt the transmission shudder, and lag with a humming noise. It felt like the transmission mission was slipping and shaking with no acceleration power. I had to keep hitting the gas pedal to try and make the transmission engage. Very Dangerous! The transmission would also throw you back and jerk when accelerating violently. The transmission lunges forward and jerks into gears when starting from 0 mph.

While driving the vehicle with auto stop engaged, the auto stop was malfunctioning. When I get to a red light or stop sign vehicle would engage auto stop, once I let my feet off the gas pedal and accelerate, the vehicle would jerk out of gear then slip /drag then engage with a loud hit as if someone rear-ended me. The problem was duplicated and confirmed by the dealership. There has been no outside inspection other than the dealership. No warning lights messages prior to failure. In addition, the Auto-stop working with a week of this complaint shortly therafter.

My 2017 cadillac ct6 3.0 Tt premium luxury has had this issue since I purchased it. Dealership state that this is normal and I should live with it. If I knew this before I purchase this $98,000 vehicle I would have gone mercedes-benz. The issues with the 8-speed 8l90 gm transmission are two-fold. First, the transmission shudders frequently. Secondly, the shifts are very harsh between first to second, and then second down to first, especially when accelerating and the transmission is upshifting or decelerating...

On more than three occasions, this vehicle has lost substantial or all propulsion due to engineering design defects with the gas/hybrid electric transmission system. All but one of these situations occurred on a high speed freeway causing potentially life threatening conditions when the vehicle substantially slowed or stopped. This is a known issue as is evidenced by other owners of this vehicle reporting the same issue and the manufacturer failing to have a viable permanent remedy. As of today's date, 3/4/2020, the vehicle has been in the shop for the past 62 of 92 days and is still awaiting repairs. This first occurred when the vehicle had less than 10,000 miles.

Transmission has a signification clunk/hesitation/delay shifting up from 1st-2nd gear and down from 2nd-1st gear. In the upshift, the car violently lunges forward once the acceleration rev from the push of the pedal catches up with the gear shifting, no matter how delicately you might push the pedal. Feels like the vehicle has been hit from behind once it catches. In the downshift, upon braking to come to a stop, the car pulsates and lunges forward as well which has caused me to nearly hit the car in front of me...

I have had issues with my vehicle that involves hard shifting at times and also, the vehicle sometimes will lurch quite abruptly. It actually feels as if the vehicle was rear ended. I have taken the vehicle to the dealership on 4 occasions and they were only able to "replicate" the problem one time. This hard shift/lurching occurs usually when at a stand still and, once you remove your foot from the brake, vehicle may shift hard. It doesn't matte where I am; whether on streets or on the freeway. If vehicle is...
