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 communicates to the dealer the process for downloading or updating operating software for the Tire Pressure Monitor, Active Fuel Injector tester, multi media tester, PICO Scope, GR8 starting/charging tester and Vehicle Data Recorder tools, giving website address and step by step instructions to complete the update.
full bulletin at NHTSA ↗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 describe a brake system riddled with distinct problems. The most recurring issue is brake pad backing plates that are too long to fit properly in the caliper carrier, causing pads to jam and wear unevenly—one side worn completely to metal while the opposite side shows almost no wear. Mechanics report needing to shorten the backing plate tabs to allow smooth movement, suggesting either a design flaw or caliper carrier deformation from repeated braking stress.
Brake fluid leaks from calipers appear after dealer service, with dealers initially dismissing squealing noise as dust rather than investigating. Dealerships consistently refuse to perform substantive repairs, instead applying lubrication per their standard procedure despite owners complaining on nearly a daily basis.
More serious failures include complete brake engagement loss, with one owner reporting an accident at 30 mph when brakes would not respond. Another owner experienced engine surge combined with brakes unable to stop the vehicle, resulting in a crash; mechanics attributed it to ABS triggering due to front wheel bearing deterioration. Brake line corrosion led to another accident. One vehicle's brakes seized completely, requiring an engine replacement. Throughout, GM has denied warranty assistance on these failures.

Failure modes owners describe
Brake pad jamming in carrier / uneven pad wear
Brake pad backing plate tabs too long to fit freely into the caliper carrier, causing pads to jam. Uneven wear develops—one pad wears completely while the opposite pad shows no wear, sometimes with a heavy rust ridge. Mechanics report needing to shorten the backing plate tabs to allow smooth movement. Issue appears on both driver and passenger sides but often worse on driver side.
When: Reported at 86,000 miles; also after dealer brake service (two years prior in one case)
Symptoms owners cite: Brake pads jammed in caliper carrier; Uneven brake pad wear; Pads difficult or impossible to remove by hand; Rotor scoring and rust ridge formation; One rotor shows metal-to-metal contact while opposite shows no wear
Repairs/costs cited: New brake pads also exhibit the same fit problem. Driver side backing plate tabs required more shortening than passenger side. Mechanics report the caliper carrier may be bent or twisted from repeated braking stresses, preventing proper pad insertion.
Recalls/TSBs owners mention: Dealer performed brake service without correcting the underlying design flaw; owner later paid out of pocket for rework.
Brake fluid leaks from caliper
Caliper develops leaks, losing brake fluid. Occurs after dealer brake service. Owner complains of noise and squeaking for months; dealer initially attributes to dust. Eventually diagnosed as broken caliper with fluid leak.
When: 6 months after dealer brake service
Symptoms owners cite: Brake fluid leaking from caliper; Squeaking and noise from brakes; Worn brake pads requiring replacement
Repairs/costs cited: Dealer estimate: $550 for caliper and pads; $1,000 for both rotors. Dealer deemed vehicle unsafe to drive.
Recalls/TSBs owners mention: No assistance offered; repair costs passed to owner.
Brake noise and dealer resistance to fix
Loud squealing noise from brakes reported multiple times to dealership. Dealer offers only lubrication as a fix, following their standard procedure, rather than diagnosing and correcting the root cause. Noise persists on a nearly daily basis.
When: During warranty period and beyond
Symptoms owners cite: Loud squealing brake noise; Noise occurs frequently, nearly daily
Repairs/costs cited: Dealership applied lubrication per their procedure but did not address underlying cause.
Recalls/TSBs owners mention: Dealer acknowledged noise issue but refused substantive repair; GM stated nothing could be done.
Brake engagement failure / unresponsive brakes
Brakes fail to engage or respond, leaving pedal at full floor with no stopping power. One owner experienced complete brake failure during attempted stop at low speed. Another report describes an incident where the engine surged uncontrollably and brakes were unable to stop the vehicle, resulting in a crash; mechanics attributed the problem to ABS triggering due to front wheel bearing deterioration.
When: During normal driving at stop signs and low-speed parking maneuvers; one incident at 30 mph; one during engine surge event
Symptoms owners cite: Brakes will not engage or respond; Brake pedal goes to floor with no stopping power; Engine surge with inability to stop vehicle; Crash resulted from brake failure
Repairs/costs cited: One owner reported mechanics said the surge/brake issue was an ongoing problem with no remedy. Another case involved ABS deterioration linked to worn front wheel bearing.
Recalls/TSBs owners mention: Manufacturer denied assistance with repairs.
Brake jerking and slipping at complete stop
Vehicle exhibits jerking or slipping sensation when coming to a complete stop. Problem occurs on nearly a daily basis. Dealership lubricates the system per procedure but does not correct the underlying mechanical cause.
When: During normal stopping, especially at stop signs and slow-speed maneuvers
Symptoms owners cite: Jerking or slipping motion when braking to complete stop; Problem occurs almost daily; RPMs increase and vehicle lunges during low-speed braking
Repairs/costs cited: Dealership lubrication applied per their standard procedure; no permanent fix undertaken.
Recalls/TSBs owners mention: Dealership refused substantive repair; owner believes GMC unwilling to spend money to fix the issue.
Brake line corrosion and failure
Brake line rusted, leading to brake system failure. Accident occurred at 30 mph. Brakes had been serviced the prior year, suggesting corrosion occurred relatively quickly after service.
When: Less than one year after brake service
Symptoms owners cite: Brake line rust and corrosion; Brakes failed, causing accident
Repairs/costs cited: Owner reports brakes were serviced the prior year.
Brake-related engine stall after seizing brakes
Brakes seized independently, causing the vehicle to stall. Dealer diagnosed that a new engine was required as a result of the incident.
When: At 100,000 miles
Symptoms owners cite: Brakes seized independently; Vehicle stalled
Repairs/costs cited: Dealer diagnosed new engine required.
Recalls/TSBs owners mention: Manufacturer notified but denied assistance with repairs.
Service stabilitrak and traction control malfunction triggered by brake sensor issues
Service StabiliTrak and traction control warning lights illuminate during driving. An independent mechanic previously replaced the brake sensor, fuses, solenoids, and other unknown parts, but the failure recurred.
When: At approximately 230,000 miles
Symptoms owners cite: Service StabiliTrak warning light illuminates; Traction control warning light illuminates
Repairs/costs cited: Independent mechanic replaced brake sensor, fuses, solenoids, and several other unknown parts; issue recurred.
