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.

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 2005 Tahoe has a systemic brake line corrosion problem. Owners report steel brake lines rusting through and rupturing without warning, often near where lines contact the frame or the rear axle. Failures occur as early as 48,000 miles on vehicles only 7–8 years old. When a line ruptures, brake fluid leaks out completely and the pedal drops to the floor with zero stopping power. No warning lights illuminate beforehand in most cases, and owners describe no prior fluid drips to alert them. Several owners lost brakes while driving at highway speed or during routine stops, relying on parking brakes and transmission downshift to stop safely.
Dealerships and independent mechanics report seeing this frequently on Chevy trucks in this generation. Owners who had brake work done recently (pads, rotors, calipers) confirm those components were not the cause. One mechanic noted the stainless steel lines were failing and recommended non-rusting materials going forward. Repair costs range from $506 for rear lines alone to $1,700 if all lines need replacement. Owners also report a frayed EBCM power wire near the firewall causing repeated ABS and stability control warnings that clear when the vehicle dries, suggesting moisture-driven electrical corrosion. One rear hub assembly failure caused loud grinding and risked wheel separation.

Steel brake lines corrode internally and externally due to road salt and moisture exposure, causing them to rupture without warning. The corrosion affects both front and rear lines, with ruptures occurring at various points including where lines contact the frame and near the rear axle.
When: Mileage ranging from 48,000 to 100,000 miles; vehicle ages 7–8 years old
Symptoms owners cite: Brake pedal goes to the floor with no braking pressure; Complete loss of brake fluid from ruptured line; Brake warning light may or may not illuminate before failure; No advance warning signs (no prior fluid drips observed); Loss of brakes while driving at highway speed or during normal operation
Repairs/costs cited: Replacement of rear brake lines costs $506–$1,700 depending on whether front lines also need replacement. Owners report mechanics recommend using stainless steel or rust-resistant materials instead of standard steel lines.
Electronic brake control module (EBCM) failure accompanied by frayed wiring near the firewall. The wire insulation deteriorates, likely due to abrasion and corrosion from road salt, causing intermittent electrical faults that trigger multiple warning lights when the vehicle is wet or just after washing.
When: Reported around February 2012 on vehicle that was regularly used
Symptoms owners cite: Service Stability warning message on display; ABS warning light; Traction control light; Brake failure light; Lights appear after washing or during rain; Warnings disappear when vehicle dries
Repairs/costs cited: EBCM module replacement did not resolve the issue. Root cause identified as frayed wire near firewall powering the EBCM; wire replacement resolved the problem.
Rear wheel hub assembly deteriorated, causing metal-on-metal grinding noise and posing a serious safety risk of wheel separation during operation.
When: Failure occurred during normal highway driving
Symptoms owners cite: ABS and traction control lights come on; Loud metal-on-metal grinding noise from rear; Risk of wheel detachment
Repairs/costs cited: Hub assembly and brake pads replaced. Owner noted they were fortunate the wheel did not separate.
Center high-mounted stop lamp (CHMSL) LED panel requires replacement.
When: Not specified in narrative
Symptoms owners cite: Inoperative third brake light
Repairs/costs cited: Replacement cost listed as approximately $300.
Synthesized from 17 NHTSA owner complaints — unverified consumer allegations, summarized for patterns. The verbatim filings appear below.
It's a documented issue but not catastrophic. 17 complaints have been filed. Repairs average $450 and most owners catch it before it causes a breakdown.
Across the 16 complaints that reported odometer mileage, most brakes failures cluster between 67,000 and 110,000 miles, with the median around 96,000. A quarter of owners report trouble before 67,000; a quarter make it past 110,000. Maintenance history matters more than the odometer alone — this is the reported failure window, not a guarantee.
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.
