What stands out
Among the 6 model years of Cadillac CTS in our records for brakes problems, this one ranks #3 by owner-complaint volume.
No new NHTSA brakes complaint has been filed on this vehicle in over 15 years — the issue may be aging out of the active population.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering brakes on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
This Preliminary Information communication provides information to the technician about changing the tire and wheel size on vehicles. General Motors will only support a tire calibration for tires that have been sized, tested and designed for the vehicle in question and its applications. Technician should not use the information that is provided by the antilock braking system tire size selection.

The failure pattern owners describe
Owners report two dominant brake failure patterns in the 2005 CTS. The first is intermittent and evasive: during low-speed sharp turns—especially pulling into parking spots—the ABS system appears to engage abnormally, preventing the brakes from stopping the car. The pedal goes soft or to the floor. No dashboard warning lights appear, no diagnostic codes pull, and dealers cannot recreate the issue. This has happened repeatedly to owners over years of ownership, with some nearly hitting parked cars, garages, and guardrails.
The second pattern is corrosion. Brake lines rust through prematurely starting as early as 24,000 miles, causing fluid leaks and loss of braking pressure. Owners cite visible corrosion, puddles under the car, and hissing when braking. Some have had lines replaced twice; corrosion recurs within weeks. One case documented a hose-to-tube interface failure; another showed both front hoses rupturing at highway speed.
Several owners report brake pedal pushing back, rotor grinding into pads, and ABS activation on dry roads without warning. One owner's emergency brake does not hold the vehicle. Dealer responses range from inability to diagnose to stating brakes function as designed. Multiple owners note the issue appears across 2004–2007 CTS models and cite NHTSA recalls that do not include their vehicles.

Failure modes owners describe
ABS activation causing brake loss during low-speed sharp turns
During low-speed sharp turns—especially pulling into parking spots—the ABS system engages abnormally, causing the brakes to become unresponsive or require excessive force to stop. Owners report the car will not stop despite applying braking pressure. No diagnostic codes are pulled; brake indicator lights do not illuminate. Dealers and independent shops cannot diagnose the issue.
When: Low speeds (10 mph or less), sharp turns, parking lot maneuvers
Symptoms owners cite: Brake pedal goes to floor with no stopping force; Rough braking feel during sharp turns; Requires excessive pedal pressure to stop; ABS activates but does not pull diagnostic codes; No brake warning lights illuminate; Intermittent; cannot be recreated at dealer
Repairs/costs cited: Dealers unable to diagnose or reproduce; no permanent repair documented
Brake line corrosion and leakage
Brake lines corrode prematurely, leading to fluid leaks and complete loss of brake pressure. Corrosion occurs as early as 24,000 miles on some vehicles. Some owners have had brake lines replaced multiple times; corrosion recurs within weeks. Leaks are visible and occur near the fuel filter area in some cases.
When: 24,000–158,000 miles; some failures early in ownership
Symptoms owners cite: Brake fluid warning light illuminates; Visible brake fluid puddles under vehicle; Brake pedal travels to floor with no pressure; Excessive force required to stop; Hissing sound when depressing brake pedal; Complete loss of brakes at highway speed
Repairs/costs cited: Replacement of brake lines by dealership and independent mechanics; corrosion recurs despite repairs. Costs cited: $2,500 for dealer diagnostic attempts; hose-to-tube interface replacement needed.
Recalls/TSBs owners mention: NHTSA Campaign 10V105000 and 15V225000 cited; most owners' vehicles not included in recalls. Manufacturer refused remedy in at least one case.
Brake hose rupture at highway speed
Both front brake hoses rupture while vehicle is being operated at highway speeds, resulting in sudden loss of all braking capacity and fluid.
When: Highway speed operation; one case documented at ~55 mph
Symptoms owners cite: Both front brake hoses rupture simultaneously; Complete loss of brake fluid; Inability to stop vehicle; Brake pedal goes to floor
Repairs/costs cited: Brake hose replacement required
Brake system failure following impact or ABS sensor work
After minor curb contact or impact (or in one case after ABS/stability sensor replacement), the ABS/stability control system malfunctions, causing complete loss of brakes for several seconds. Brake pedal goes to floor; brakes then return after the warning clears.
When: Immediately after impact or sensor work
Symptoms owners cite: Stability control warning appears after impact; Brake pedal travels completely to floor; No braking force available; Brakes suddenly return after 3–4 seconds; Vehicle drifts or hard-steers due to brake loss
Repairs/costs cited: One case: stability sensor replaced; another case: GM repurchased vehicle
Recalls/TSBs owners mention: One case: GM repurchased vehicle but refused to cover damage caused by brake failure
Brake pedal pushback and abnormal ABS behavior
Brake pedal resists or pushes back against foot during braking, or ABS activates on dry road for brief periods without warning light. Dealers find no issue and advise brakes are functioning as designed.
When: Low speed, dry road conditions, early in ownership
Symptoms owners cite: Brake pedal pushes back against foot; Unexpected ABS activation on dry roads; Service Brake Assist message on screen; ABS/traction control lights illuminate
Repairs/costs cited: Dealers advise no problem found
Rotor-to-pad grinding and wear
Grinding noise from braking system for months; dealer cannot reproduce. Rotors eventually grind into brake pads, causing severe damage. Failure occurs early in ownership (24,000 miles).
When: Early ownership; detected at 24,000 miles
Symptoms owners cite: Grinding noise from brakes for ~8 months; Rotors grind into brake pads; Severe brake component damage
Repairs/costs cited: Severe damage to rotors and pads; manufacturer declined to assist
Recalls/TSBs owners mention: Manufacturer stated nothing could be done to assist
Emergency brake (parking brake) inoperative
Emergency brake pedal does not hold vehicle; vehicle rolls freely even when emergency brake is fully depressed.
When: At rest; timing not specified
Symptoms owners cite: Emergency brake pedal pressed to floor with no effect; Vehicle rolls despite engaged emergency brake; No holding force from emergency brake

The brakes will slip when applied. It seems it only happens when going a low rate of speed. In november of this year I had recall on bakes fixed. I thought that had fixed problem. Unfortunately the brakes started slipping again yesterday (dec. 29, 2010). I have had brakes checked several times in the past, no one can seem to find a problem. This is our family car and I am beginning to fear for…
Tl*the contact owns a 2005 Cadillac cts which was purchased in 2004. He heard a slight grinding noise coming from the vehicle for eight months. The dealer could not duplicate the problem. On a separate occasion, he heard a grinding noise coming from the braking system. Upon further investigation he found the rotors had ground into the brakes and pads which caused severe damage. The manufacturer…
When ever I make a slight turn at low speeds,ie. 10 MPH or less the ABS actuates and the car is unable to stop. This is very prevalent when pulling into a parking spot. I have had firestone auto, parker cadilac, and american tire and auto in my hometown look at this issue and all told me that they could not pull codes. I have been told that if any indicator dash warning light come on then it…
