Brakes fail when making sharp turns. I contacted GM and they claim to have never heard of the problem, I've had it fixed last year and it is starting to happen again.

My back center brake light no longer works and since this was pointed out to me earlier this month, I have noticed at least four other Cts cars with the same issue. They range from my year ('06) to at least 2009. And when quoted a price ($600+!) I balked at having it replaced. Anyone else notice this or have this issue?

May '15 noticed small pink puddle of fluid on the garage floor under front passenger side. New set of brakes put on in Jan '15 so drove to my mechanic. When I did a hard left into the parking spot at 2-5 mph the car brake pedal shuttered, went to the floor and I was barely able to stop. Mechanic had it for 3 hrs trying to figure out the problem/test driving it many times. They could not find anything wrong. Two weeks ago the "service brake assist" dash message came on. I looked it up on the computer. I found over 75+ complaints of other Cadillac Cts owners with the same problem. All of them had their mechanic or dealer look at the problem. Most of those failed to find any problem or repaired things that did not fix the problem. Almost everyone said GM should do something or at least let owners know. The situation is very dangerous. I also came across the way to fix the problem from a complaint forum poster : "it is a wiring harness problem - have your mechanic check the wiring harness for sources of inductive voltage. Eventually, an intelligent mechanic fabricated a new harness with new terminal grounds from the ebcm to the left wheel speed sensor and rerouted the harness away from any possible sources of inductive voltage. Once that was complete, we have not had a problem. The mechanic (works for dealership) said to us that anecdotally he has run into this problem more than once and that there seems to be a failure in the design /workmanship in some of the wiring harnesses connecting the ebcm to the speed sensors that causes the brakes to fail. Separately, he recommended the next time we buy a car, we not buy a Cadillac, because he felt that the fix -- rerouting the harness -- was not a time or money intensive fix, but that GM didn't seem interested in letting car owners know that, despite the potential and obvious dangers. More but out of room.

While very slowly turning into a parking spot my 2006 Cadillac Cts acted as though the ABS was engaging and would not stop. I had to manually put the transmission into park to stop. This has now happened 4 times under similar scenarios. Each time this happens 'service brake assist' appears on the driver display and the T/C and ABS lights come on. After the car has been shut off and then restarted the display is normal, dash light S are out and things work normal, until it does it again. I am in Canada, but after researching this problem have found many, many similar incidences and felt adding to the list may help to engage GM to issue a recall.

The contact owns a 2006 Cadillac Cts. While reversing out of a parking space at approximately 2 mph, the brake pedal was depressed but the vehicle did not stop. The contact observed that the brake hose had ruptured and the check brake fluid level warning indicator illuminated. The vehicle was not taken to a dealer or diagnosed. The manufacturer was made aware of the failure and stated that the VIN was not included in NHTSA campaign number: 10V105000 (service brakes, hydraulic). The failure mileage was 110,000.

While making a right turn pulling into a parking spot the vehicle failed to stop until it hit the curb. Since then it has happened several other occasions very sporadic but the situation is the same while pulling in to a parking spot brakes fail to engage as if I have no brake assist. Today it happen again this time I hit a gate causing damage to my front bumper as well as the gate. I understand that this is a on going problem and GMC has failed to acknowledge. Please help us before it causes someone's life because of a fatal accident caused by this problem.

The car will not stop when turning into parking spaces, coming up to stop lights or going down hills. When this started happening, I thought I just needed new brakes. I went to the mechanic and replaced my brakes and got new tires, but the issue continued. In order to stop, I have to put the car in park while it is rolling. I pump the brakes, but that does not help. I have almost rear-ended vehicles while coming to stop lights. I have almost ran into light poles while parking my car. I have rolled out into the street on numerous occasions because the vehicle will not stop. All of these examples happen sporadically but often. My traction light and ABS light come on and I receive a warning on my dash stating "service brake assist". I have been very lucky so far that I have not been in or caused an accident, but I am extremely fearful that eventually this will happen.

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).

I had just exited the highway and waited at the end of the ramp for the traffic signal to change. I was proceeding into the intersection after waiting for light to change. I began to accelerate and another car ran the light and hit my car on passenger side. The responders said I was T-boned. When I got hit the car steering wheel locked up, the car came out of gear, the gear mechanism inside the car came apart, the brakes didn't work. I had no control of the car, it shut down. The only thing that stopped me from hitting the metal guardrail was the car ended up on the curb on left of road in the bushes. The passenger window shattered and windshield on passenger side was damaged. The passenger door was pushed into the car and neither of the airbags deployed. The responder's commented that they were surprised that the airbags didn't deploy as hard as I was hit. The vehicle has been deemed a total loss as the damage is extensive. Previously on a few days have had to jiggle the steering wheel and the keys in ignition to turn so that I could start my car. I had previously checked the GM site and entered my VIN because I had times when the ignition switch in my car would not work. There was no recall for my vehicle.

Several times I have experienced that when turning right into a parking space my car does not want to come to a stop, my brakes become hard and to come to a stop I have to keep pumping the brakes.I am very scared to even go into a parking space.dont know if my car is gonna stop or keep going.the first time this happened to me is when first purchased the car, but being that U can use this car as stick or standard I thought maybe I did something wrong, I almost went into my apartment building.I am afraid that I might get into an accident with my grandchildren in the car or even hit someone walking.
