CTS 8-cyl

  • 112,000 miles


I observed a large puddle of brake fluid around the front left tire. Upon removal of the wheel, I discovered a large brake fluid leak at the interface between the hard brake line going to caliper and the flexible line that goes to the body of the car. During removal, the interface completely failed. This is exactly the failure that was involved in recall: Report receipt date: Mar 17, 2010 NHTSA campaign number: 10V105000 component(s): Service brakes, hydraulic yet for some reason, this recall was limited to vehicles sold and registered in a certain number of states. This brake line obviously is failing on vehicles registered in other states. The part on my car was within several cycles of complete failure, which would have meant loss of braking and a crash. I have retained the failed part and can provide photos or make it available for analysis.

While entering a parking place, my brakes failed to engage. The ABS system warning appeared and also the traction control warning illuminated, as I struck a restraining post. This could have been tragic if a person had been infront of the vehicle. Less than 2 weeks prior to this I had a complete brake service and replacement of all worn equipment. Now I am concerned for anyone driving this vehicle or anyone walking in front of this vehicle. I took the car back into my local garage to have the brakes rechecked. They found no problem. My plan was to take the car to the GM dealership where I purchased the car, yet, I find that this is a common problem and GM refused to help others with the same problem. They, others with the same problem, spent lots of money and to no avail. The problem has not been repaired at the dealerships and have left the customers very dissatisfied.

Car would not stop at low rates of speed on multiple occasions. Have had to throw it into "park" gear to make it stop. Have changed brake sensors on all four wheels, ebscm system, and problem still occurs. "service brake assist" light came on after multiple episodes occurred. Have had it into Cadillac dealership on numerous occasions and continue with same problem. Aware this has occurred on many cars of same make/model and year via internet search.

TL-the contact owns a 2004 Cadillac Cts. While turning right at any speed with the brakes engaged the vehicle would not stop. The vehicle would not stop until the steering wheel was returned to a straightened position. The failure recurred intermittently while braking and making right turns. The failure recurred more frequently during rainy conditions. During the failures a brake assist light would also illuminate on the dashboard. The vehicle was not taken to have the failure diagnosed. The manufacturer was notified and the contact was told the vehicle was not included in the recall associated with NHTSA campaign id number 10V105000 (service brakes, hydraulic:foundation components:hoses, lines/piping, and fittings). The vehicle was not repaired. The failure mileage was 50,000 and the current mileage was 78,000. Sm.

I own a 2004 Cadillac Cts with no previous problems except for responding to several recalls. Several days ago, I was moving forward into a parking space at about 3 miles/hour. I pressed the brake pedal and suddenly the pedal went almost to the floor and I barely stopped inches from the car in front. I was not stepping on the accelerator at the same time. Immediately after the incident the brake pedal felt normal but two loud bursts of air, 2-3 seconds each, occurred. The Cadillac dealer finds nothing in computer checks, road tests, and visual inspections and does not know how to fix the problem. The edmunds.com townhall web site contains several reports of exactly the same problem with the Cadillac Cts.

ABS brakes would kick in when attempting to park the vehicle at about 5 mph. The only way I could stop the car was to throw it into park or hit the emergency brake. It was happening about 2 times every month or two. Very randomly. I kept brushing it off until one day I almost hit a person. The ABS and tc warning lights would come on the dash and then go away when restarting the vehicle. I then decided to take it to the Cadillac dealer and he told me that it was probably the ABS sensors. This was on Oct. 12, 2010. As it turned out, I had to replace the left front hub bearing assembly at a cost of $659.41. The name of the Cadillac dealerwhere I had it repaired is faulkner Cadillac, 298 stoke park road, bethlehem, pa..phone # 610-867-4177. My customer on the receipt is #73324, and the invoice # is 1007398. The mileage at that time was 50,590. The repair date was Oct. 12, 2010. Since I had it repaired, I haven't had any more problems. I'm sure that I'm not the only one having this problem and I think it should be looked into before someone gets seriously hurt. I realize it would be an expensive recall on GM's part but a necessary one. Thank you, james fazakas phone # 610-866-2238

Sporadic brake failures on a 2004 Cadillac Cts. Car has had front left hub/speed sensor assembly replaced 4 times per authorized dealership recommendation starting at <20K miles. Brake failure occurring every few days, typically at low speed but now starting at higher speeds. Nearly ran over pedestrian in parking lot. Accidents have been avoided thus far.
