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.

Cruise control will randomly turn off and will be unavailable for a few days then come back. Engine seized up out of nowhere while driving down the road and nearly caused an accident due to it locking up while moving.

I had adaptive cruise on, was at a stop light, so adaptive stopped, the truck in front of me moved because the light turned green, so to engage the cruise I gently gave it gas and I felt the cruise kick so I moved my foot and then the car lunged into the trailer hitch of the truck in front of me. I had no time to react, the crash warning did not flash nor did the braking assist engage. Luckily the guy I hit was not affected the hitch prevented damage to his truck but my car took all the damage. I was so shook that before I could apply brakes my car still was trying to move forward even though it had hit the hitch. This was on a highway just as it was merging to a street. I contacted cadillac/gm and sent them pictures and 2 days later they called and said I had no case, they did not even send me to a dealer to check out the system by a professional.

Went to pull into a parking spot, hit the brake, the car sped up hitting another parked car. I had a problem yesterday, put car in cruise control(50 MPH) on the highway, went to brake to turn, cruise control would not disconnect, had to shut the system off manually. Similar periodic problems in the past.

I own a 2007 cadillac cts. On monday, march 17th, at 5:45am, I was driving south bound on I-75. While driving with the cruise control on, traveling around 77 MPH, at about mile marker 88, I heard a large thud noise like something hit the underbody of the vehicle. I then heard a loud metallic ringing noise and felt a vibration through the vehicle floor and steering wheel. I put my turn signal on to get over to the shoulder of the road. As I turned my head to the right to see if it was clear to get over, I noticed a large cloud of black smoke emitting from the back of the vehicle and could see an orange reflection of flames in the driver's door of the vehicle to the right of me. I got over to the shoulder at mile marker 87. I inspected the vehicle to see what was going on, I looked at the left side and didn't notice anything, then walked over to the right side of the vehicle (I was standing about 10 ft behind the vehicle on the right side) and noticed flames shooting out from under the engine compartment. I walked back about 50 feet and called 911 and reported the vehicle fire. The independence township sheriff's office responded about 5 minutes later and was going to attempt to put the fire out, but by that time the flames were shooting out of hood of the vehicle. The flames were about 4 to 5 ft at that time and the officer decided not to attempt to put the fire out. Fire department showed up about 10 minutes after the sheriff was there and put the fire out. I had the vehicle towed to randy weiss gm dealer in fenton, michigan. Vehicle mileage 74,665 miles. Vehicle maintained either by lasco ford in fenton michigan or al sierra in grand blanc michigan.

Had my cruise control set at 70 MPH for highway driving when I heard a psshhh sound and cruise control broke violently and smelled burnt rubber with smoke coming from back end of car. Pulled over immediately and car smoke from back end and smell only increased. Thought for sure I had a tire blowout. Walked around car and nothing wrong with tires. Had car towed to an auto repair place and am told that the rear differential went out. I have since investigated and found many, many forums about this issue. There are no recalls for this particular model but a certain recall for 2005 models. This situation could have been deadly and I feel both fortunate and upset with gm that such a problem has been so commonly noted but with no "real" resolve. The auto repair place has called around and this is a special part that is not available in my state and a new one costs an estimated $1,200. With so many issues with models 2004-2006 how come there is no recall for 2004 and only a lesser degree of a recall for 2005?

I purchased this vehicle in november 2011 with approx. 97,000 miles showing on the odometer. During a thanksgiving holiday trip of some 1600 miles, consisting mostly of highway driving with the cruise control engaged, and for no apparent reason, the asc (automatic stability control) would disengage the cruise control, "tug" the vehicle to the left or right slightly, seemed to have a slight braking effect (although it may have been the sudden deceleration that caused the sense of braking) and would display " stability control engaged". This occurred numerous times. Also, on this same trip, the "traction control" would engage, without warning or need, and disengage the cruise control causing sudden, unexpected, deceleration. This too happened numerous times. Although I did notice that the "traction control" seemed to engage when in a curve on rough or bumpy roads. I concluded that this was the result of a sudden "wheel hop" or "spin" as a result of losing traction from the "bounce" when hitting a bump or rough spot. I've run the "onboard diagnostic system" several times and no codes pertaining to these events are displayed.
