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 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)

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 .

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.

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 recognize any tire damage or issues. During our 5 hour drive to San Antonio, we started to see tire pressure issues again along with a noticeable sound from the tires. With this concern, we took vehicle to Firestone for diagnosis and to our surprise they found severe damage and cracks to the side walls of the tires. Firestone confirmed the tire damage was not safe to drive on and due to the location of the damages, we would need to replace all 4 tires. We were shocked to see such severe cracking damage and were at a loss for how this could occur. The tires were in very good condition and still had significant tire tread with even wear. After some research we discovered that this type of side wall tire cracking has been know to happen and even Pirelli has recalled tires for this issue. We did not see a specific recall to this size tire but did find that Pirelli had another recall on tires made in 2016 saying "THE PROBLEM WAS CAUSED BY A PRODUCTION ERROR (INCORRECT CARCASS COMPONENT), AND THE TIRES MAY SHOW SURFACE CRACKING IN THE LOWER SIDEWALL OF THE TIRE...". Please review this claim and confirm receipt. We are hoping to get some kind of reimbursement for the damages that we believe are a result of faulty or defective tires - this is what the Firestone technician also stated on video recording (I can provide video if needed).

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.
