I was traveling on a local highway at the posted speed limit when I was caused to slow due to traffic. When I pressed the brake pedal the pedal went completely to the floor. Scared to death I almost engaged the emergency brake to ensure the vehicle would stop in time. Mind you I was traveling with three children and my spouse in the vehicle all of whose lives could have been affected not to…

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.
The failure pattern owners describe
Brake line corrosion is the dominant failure mode. Owners describe steel lines rusting and rupturing, causing sudden brake fluid loss and complete brake failure—brake pedal goes to the floor with zero resistance. Most concerning: many failures happen with no warning light until the pedal is already on the floor. One owner had three children in the vehicle when brakes failed at highway speed. Another nearly hit a tree. Owners in Virginia and Michigan report corrosion despite not driving in salt-belt conditions or limiting salt exposure. Repair bills run $1,500–$3,660, with some requiring body panel removal. One owner's dealer confirmed all brake lines were corroded and unable to hold pressure.
Beyond line failure, the ABS system engages uncontrollably at low speeds, causing brake grab and longer stopping distance. One owner disabled the ABS fuse after researching similar problems GM apparently recalled in Canada but not the US. Another owner brought the vehicle to a shop multiple times for intermittent brake failures the dealer could not reproduce. A master cylinder replacement did not fix recurring brake failure. Parking brake cables snap and fail repeatedly, even after being replaced with new correct parts. One owner also reports the dynamic brake system activating on its own, overheating rotors and causing tire blowouts. GM attributes corrosion to salt use, but owners are finding this isn't the cause in their cases.
Failure modes owners describe
Brake line corrosion and rupture
Steel brake lines corrode and rust, causing fluid leaks, loss of braking pressure, and complete brake failure. Multiple owners report lines failing despite vehicles not being driven in heavy salt conditions or only occasionally driven. Corrosion occurs in non-salt-belt states including Virginia and Michigan.
When: Various mileage and years of ownership, ranging from newer vehicles to those with 73,100 miles; some failures occur within first few years of ownership
Symptoms owners cite: Brake pedal goes to floor with no resistance; Gradual loss of brake pressure requiring increased foot pressure; Brake fluid pooling or dripping under vehicle; Visible rust and flaking on brake line components; Service brake warning light and dinging alerts (often only after complete failure)
Repairs/costs cited: One owner cited $1,500 for brake line replacement plus $300 for rear rotor and parking brake pad damage. Another reported $3,660 for lines, rotors, pads, fuel pump, backing plates, and level sensors. A third owner replaced a brake line at a shop but required dealer completion due to body panel removal needed.
Recalls/TSBs owners mention: Owner #2 states dealer confirmed all brake lines needed replacement as they would not hold pressure and were rusted. GM reportedly attributes corrosion to salt belt conditions despite vehicles being registered in non-salt areas. No recall issued; owners reference Canadian recalls for similar problems not implemented in the US.
ABS system malfunction with grabbing and loss of control
Anti-lock brake system engages intermittently during low-speed driving or on its own while vehicle is running, causing brake grab, shaking, loss of speed, and extended stopping distances. Display shows 'Service Stability' warnings. One owner disabled ABS by removing the fuse after researching similar issues.
When: Occurs intermittently; owner #6 documented increasing frequency (once in June, twice in July, multiple times in August)
Symptoms owners cite: ABS system grabs intermittently at low speeds (3-5 mph); Vehicle shakes and loses speed drastically; Extended stopping distance with ABS engaged; Service Stability message on display; Issue resolves temporarily after shutdown and restart
Repairs/costs cited: Owner #9 removed ABS fuse after research. Owner #6 states the vehicle had to be taken to a repair shop due to safety concerns.
Recalls/TSBs owners mention: Owner #9 notes GM has not recalled this in the US, though mentions a national recall to solve similar problems in Canada.
Master cylinder failure
Master cylinder fails to maintain brake pressure, resulting in complete brake failure. One owner reported master cylinder replacement by dealer did not resolve the issue; brakes failed on two additional occasions with dealer unable to locate the root cause.
When: Unknown; owner experienced multiple failures over unspecified time period
Symptoms owners cite: Brake pedal goes to floor; Complete loss of braking ability; Recurring failure even after master cylinder replacement
Repairs/costs cited: Service dealer replaced master cylinder; repair did not correct the issue.
Parking brake cable or component failure
Parking brake cable or connector snaps off under the dash, rendering the parking brake inoperative. One owner had the same component fixed two years prior and it failed again in the identical manner despite using new correct parts.
When: Repeated failure; first repair two years before complaint, then failed again
Symptoms owners cite: Parking brake inoperative; Cable or component snapped beneath dash
Repairs/costs cited: Owner paid Classic Chevrolet for repair two years prior; replacement used all new correct parts but failed identically.
Dynamic electronic brake system overheat and uncontrolled activation
Dynamic brake system activates intermittently during normal driving, causing excessive heating of rotors and rear components. Strong brake smell accompanies activation. Owner reports rear tires exploded on two occasions resulting in highway accident. Issue persists despite dealer replacement of brakes, ABS, and related components in 2005 and again in 2010.
When: Recurring throughout ownership; vehicle has 73,100 miles as of complaint; new in 2005
Symptoms owners cite: Dynamic electronic brake system turns on during driving without braking input; Rim and rear brake components heat excessively; Strong brake smell during activation; Rear tire blowouts (two occurrences); Vehicle shaking
Repairs/costs cited: Dealer replaced brakes, ABS, and related components in 2005 and 2010; issue remains unresolved.
Recalls/TSBs owners mention: Dealer stated they were not responsible for the problem.

What owners are reporting 2 most recent
Driving home, leaving our current locality the brakes failed to work. Were able to press brake to the floor without having the vehicle stop. Investigated the next day (after having to borrow a vehicle) and brake lines are flaking and leaking fluid. Took to repair shop after putting on "temporary" break line (which we found out will not work on our vehicle). Having it replaced but shop…

At what mileage does the brakes typically fail?
Across the 11 complaints that reported odometer mileage, most brakes failures cluster between 65,000 and 116,414 miles, with the median around 101,000.

What does it cost to fix?
Independent shops typically charge around $450 for brakes repairs on this vehicle. Dealer pricing tends to run 20-40% higher. The exact figure depends on the specific failure mode, parts availability, and your local labor rates. If you're outside factory warranty, an extended service contract often covers this category.
Are there any recalls related to brakes?
No active recalls currently cover brakes issues on this vehicle. The complaints filed represent owner-reported failures that haven't risen to the level of a manufacturer-issued recall — but they're still worth knowing about before you buy or budget for repairs.
