Each bar shows the share of total complaints filed at that mileage range. Peak failure window highlighted. Some owners report problems earlier; some make it well past 150,000 miles symptom-free. Maintenance habits and driving conditions shift the curve as much as mileage alone.
What stands out
No new NHTSA brakes complaint has been filed on this vehicle in over 11 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 of 2005 Yukon models report premature, sudden brake-line failure caused by rust and corrosion. The problem strikes across a wide mileage range—one owner hit it at 62,000 miles, others between 118,000 and 127,000—and the failure is total: the pedal goes to the floor with no stopping power. Lines rupture at connection points where plastic clips hold them, along the line route near the ABS module, and at caliper connections. One owner's vehicle lost all four lines plus transmission cooler lines simultaneously. Brake fluid puddles form under the vehicle, and the aluminum ABS distribution box corrodes alongside the lines.
The failures happen in heavy traffic, at stop signs, and in parking lots—situations where a sudden loss of braking could cause serious wrecks. One owner with three children in the car went through two intersections before stopping safely; another hit the vehicle in front at 20–25 mph. Rust-belt owners (Indiana, upstate New York) report it frequently, but California owners have experienced it too. Repair costs exceed $3,000 when brake lines rupture and corrupt rotors. GM has denied warranty claims and recalls, citing out-of-warranty status, though owners cite NHTSA investigations and online reports of similar failures. One owner reports the problem recurring even after repair.

Failure modes owners describe
Premature brake-line corrosion and rupture
Steel brake lines rust through and burst without warning, causing total or near-total loss of braking pressure. The failure occurs at connection points (plastic retainer clips), along the line route (especially in front of ABS module), or at caliper connections. Multiple lines can fail in sequence or simultaneously. Owners report rust through at mileages as low as 62,000 miles; others at 118,000–127,000 miles. The issue appears concentrated in rust-belt climates (southern Indiana, upstate New York) but occurs in California as well.
When: 62,000–127,000 miles; one owner noted failure after ~6 months of ownership
Symptoms owners cite: Brake pedal goes to floor with little or no resistance; Complete brake failure during normal driving or deceleration; Puddles of brake fluid under vehicle; Visible rust and corrosion on brake lines; Aluminum ABS distribution box corroded
Repairs/costs cited: Owners report full brake-line replacement, ABS module replacement, rotor replacement (one owner cited $3K+ repair cost after brake-line failure corrupted rotors; rotors had been replaced 1 year prior with <1K mileage). Trans cooler lines also failed in at least two cases.
Recalls/TSBs owners mention: Owners cited NHTSA campaign 05V103000 (SERVICE BRAKES) and EA11001; one owner stated vehicle was not included in recall. GM corporate denied assistance on a 2014 complaint (vehicle past warranty), attributed issue to dealership responsibility, and claimed no knowledge of brake-line defect despite owner citations of online cases.
Brake grinding/slipping noise (unresolved)
Front-end grinding or slipping sensation during braking at normal speeds. Owner reported rear-brake and front-brake replacement by two shops with no resolution. Noise returned within a month after rear-brake service. Owner questioned whether issue was structural or design-related.
When: After ~6 months of ownership; recurring
Symptoms owners cite: Loud grinding or slipping feeling from front end during braking; Noise occurs when slowing to a stop or turning at normal highway/roadway speeds; Sensation felt and heard by driver
Repairs/costs cited: Rear brakes replaced; front brakes replaced. Noise persisted after both interventions.

I was driving on a divided highway and went to slow down to make a left hand turn and the brakes initially worked but at about 30 MPH there was a total failure and the pedal went all the way to the floor. I had to stand on the pedal, so to speak, to get the 2005 yukon to stop before hitting the traffic stopped in front of me. I had the truck towed home and upon inspection the break line had…
Lost brakes completely. The was a catastrophic failure in the cluster of brake lines in front of ABS module due to rust which left a puddle containing all of the brake fluid on the ground. Luckily the vehicle was in a church parking lot when it happened and a sudden stop was not needed from a higher speed. This could have been bad if that were the case. Too bad gm did to spend a few extra…
I was pulling up to a stop light, and the brakes went out. I ran into the truck in front of me while going between 20 to 25 MPH. The auto repair shop said my brake line was corroded and it snapped. *tr
When I went to pull the yukon into the driveway, the brake pedal went to the floor and I barely made it into the driveway and stopped. I had the vehicle towed to the gm dealership. I was called within a couple of hours and told that the brake lines had burst and had corrupted all of the rotors and the cost would be over $3k to repair/replace. Note: the rotors were replaced sep 2013 and had less…
