At 45mph the right front wheel shudders. It only happens occasionally. I've checked it on very smooth roads to make sure it wasn't the conditon of the road causing the shudder. Sometimes, when the car shifts, it shifts very hard as if being bumped in the rear. I had it checked and I'm told it may be a transmission issue but not sure. The original tires are on the car and at 48 thousand miles they have worn even. I've had the front end checked for alignment and the front wheels balanced. That is not the issue.

It happened to me several times when turning into parking space or pulling out of parking space my 2006 cadillac cts 3.5 did not stop while braking the car in either direction. During that I felt a shudder sound coming out of front wheels and brake pedal traveled all the way to floor. At the same time a message ?service brakes assist? Appeared on the vehicle information display window and the ABS and traction control warning lights were turned on in the dash board. I took my car to more cadillac local dealer at chantilly, va. And get it checked in reference to recall # 09149, but he told me that is not the issue because the front brake hose fitting are not corroded and he could not replicate the issue. I contacted gm customer service on 11/06/2014 and explained the situation of the issue. They assigned me a reference # [xxx] and we had a conference call with the moore cadillac service advisor. It seems like the gm and moore dealer advisor are not admitting that is a manufacturer issue, but I have read several similar complaints on the www.safecar.gov site and fee like that it is a gm manufacturer issue and could cause a fatal accident. Currently, mileage on the car is only 59,200 and I noticed this issue at mileage 55,000. Information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6).

On 8/9/13 during a lane change on the highway under acceleration the car downshifted and the RPM went high and the car had no power and seemed to just coast. I let off the gas to let the engine rpms come back down and I checked the automatic shifter to make sure it was still in drive (and it was). When the engine rpms came down the power also came back to the wheels. I have experienced a random shudder in the car under light throttle when the automatic transmission is shifting (such as in traffic) both prior to and after this event. The dealer could not duplicate the problem during a test drive. On 5/3/14 I was backing up in a driveway upon starting the car and there were no power brakes. I pressed the brake pedal to the floor and did manage to stop the car. Once I lifted off of the brake pedal the power brakes seemed to work. This is another randomly occurring problem with this car. Upon driving the car immediately upon startup the power brakes do not seem to work for 30 seconds to a minute. I have had this problem randomly before this date (I noticed it before last winter) but it seems to be getting worse. Hopefully the dealer can duplicate this problem. On 5/6/14 I was driving on a side street and lost all engine power, power steering and power brakes. The dealer told me the engine seized up. The car had approx. 14,400 miles on it at the time of the 5/6/14 incident. The car is at the dealership now for repair. *tr updated 12/8/2014

I was driving a 2014 cadillac cts on 04/27/14, in fremont, ca. Vehicle configuration: 2014 cts 3.6l rwd performance. Vin, to the best of my knowledge: 1g6as5s39e0[xxx] the incident occurred at approximately 11am. The planned travel route was as follows: fremont cadillac, 5939 automall pkwy, fremont, ca ||| nw on boyce road ||| n on stevenson blvd ||| interstate-880s ||| exit automall pkwy ||| fremont cadillac. I traveled north on stevenson blvd and then headed for the onramp for interstate 880-south. When I approached the freeway onramp I noticed, all of a sudden, a delay between pedal application and power. I demonstrated this to my passenger twice over, by gently letting off the gas and applying it again... At which point the vehicle's check engine light came on, accompanied with a loss of traction control and stability control, reduced engine power, and shuddering during gear shifts. The vehicle was traveling approximately 40mph at the time. Aside from the aforementioned issues, no other problems with the vehicle were observed. I only traveled two miles before experiencing these issues. As this was a brand new car on a test drive, it obviously had very few miles on the odometer. Upon returning to the car dealership, the sales associates pulled the car back onto the sales lot, moved other new cars out of the way, and parked the car amongst other new vehicles for sale. The vehicle was most certainly not pulled into the service drive. Needless to say, this is unsettling news. I have no faith that the vehicle was properly inspected, nor do I have faith that the dealership will responsibly handle this matter. It is my recommendation that gm withdraws this vehicle from dealer inventory and performs an independent assessment of the vehicle. *js information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6)

I noticed that, when driving very slowly and turning sharply to left and braking car would shudder and feel like brakes not working. Finally, one day it would not stop and I almost hit a car. Took in to service center and ABS system in wheel had to be replaced. Now I am having similar experiences again and "check brake assist" and "ABS" warning lights on. When this car was 6 mos old, the ABS assembly had to be replaced. It seems that this is a design flaw in the car but cadillac does not acknowledge. Is intermittent problem and if I turn off the engine and start from straight drive, problem does not occur or register in warning system.
