I have 2 complaints. #1 The transmission shifts extremely hard in and out of gear 1. This issue a known issue, but GM has no resolution. There is a bulletin. The problem is, my car is no shifting poorly in all gears and causing a serious safety issue at all speeds and gears. It won't go into gear causing safety concerns. I have reported the transmission issue multiple times while under warranty and it is now worse outside of warranty! #2 Adaptive cruise has also been reported multiple times and I have paid to get both front sensors replaced. Only to have the issue continue. The dash will show a car is in the path, but there is a 2-3 second delay before car starts to slow down. Often brakes do not engage and the alarms just go off. I have driven a loaner car of similar years and they do not operate the same. This car is an outlier.

The component that failed on my vehicle is the rear differential. My safety was put at risk by my vehicle hesitating on the highway where I lost speed and was almost rear ended. At that point I had to pull over onto a shoulder with grass to wait on the side of the highway for a tow. My vehicle has been with the dealer for the past 2 months. No warning lights or signals.

A known issue. -??Clutch slow to fill-?? is a defect of the 8 speed transmission that causes the vehicle to violently buck and surge at low speeds and is dangerous as it makes it unreliable when driving at low speeds since it can randomly lunge forward dangerously. Dealership replaced transmission valve body under warranty and flushed transmission twice but problem remains. Dealership claims it can be fixed with an -??update-?? but tried to charge over $300 for the -??update-?? when it is a defect that should have been fixed under warranty for free or have a recall.

When I accelerated the transmission felt like it got stuck and continued to rev when I attempted to accelerate and felt like I was not moving. RPM continued to go up but no power. Other times a vig bump is felt when I take foot off gas for a koment and when I place it back on to accelerate the big bump is felt. Have taken it to Cadillac sevice twice and both times transmission was reprogrammed but it did not dix the problem.

Car has just passed the warranty. Put the car in the shop for an oil change, when I got it back I could hear a yang yang noise like I had a bad tire, in the mean time on star sent a notice that the something was wrong with the brakes and stability control. The noise could be heard at any speed. So now I have to spend $4000 for car repairs for a car not quite 3 years old? need a break, discount or something. I'm still making payments on this car.
