CT6 3.6 LUX 3.6L

  • Automatic transmission
  • 5,000 miles

Purchased this car in May of 2017. It was back in the dealership within a week due to a broken seat (no I'm not fat). Less than a month later we took it back due to the lane departure, pedestrian warning and transmission. The problems include: hard shifting, long delay from neutral to reverse, warning lights that someone is in the road when no person or car anywhere around us, car not moving when accelerator is pressed etc.

Once we took it back because when I hit the gas, the car did not move for about 5 seconds and then when it did, the tach was over 5k. I didn't let off because it did this as I was pulling out onto a busy street. The car would throw you back when shifting from 1st to 2nd gear. The car would surge when sitting at traffic lights. The car would pulsate when coming to a stop. The list goes on and on.

We took the car back to the dealership 12 times. Every time my wife took it, the service manager blamed her for aggressive driving. when I took it, he blamed her for aggressive driving. needless to say, after he accused her for the 6th or 7th time I had enough and spoke exactly how I felt. Finally after the 12th time in the shop, I decided it was time to let it go.

I traded it in at a huge loss! We paid $68,000 for the car and just 17 months later, with only 21,000 miles on it, we got $39,000 trade in. This was our first and last Cadillac.

CT6 3.0tt

  • Automatic transmission
  • 10,000 miles

This transmission in this car is terrible, it reminds me of my Lexus GS 300 that was recalled. I was given a settlement for the car that will jumps, jerk, and take off without your control. This is a big problem and I hate this car. Cadillac need to fixtures problem..Maybe this is part of the reason why they are getting rid of this car in their lineup. I think they need to give me the new CT six the sport for free.

Update from Jan 23, 2019: After the shifting problems, I took the car for service. The car is driving better but shift hard out of first gear from slow start. The car is awesome with all the bells and whistles. My original complaint was felled with frustration. I’m happy with the car over all and service took care of problem. You want go wrong with this car. A head turner. And fast.

CT6 Luxury V6

  • Automatic transmission
  • 2,100 miles

The 8L transmission on the 2017 Cadillac CT6 has proven to be the vehicle's weakness and its performance makes it an extremely unpleasant car to drive. Shift points become corrupted, shifts between 1 and 2 can be violent and downshifts cause the vehicle to pulsate as it coasts to a stop.
