Rear brake calipers are the main problem. Owners report calipers seizing during normal driving between 20,000 and 115,000 miles, leaving the brake pedal spongy and traveling toward the floor when pressed, with noticeable loss of stopping power. One owner replaced both calipers only to have them stick again one month later, damaging the rotors in the process. Another owner found metal shavings on the garage floor from corroded, rusted rotors at 48,500 miles.
Two owners report unintended acceleration incidents—one during low-speed parking that resolved only after shifting to neutral and killing the engine, and another at 40,000 miles that ended in a crash into a brick wall with injuries. The second vehicle had already been serviced under a brake campaign recall.
Hyundai recall campaign 10V613000 addresses rear caliper failures in Santa Fes built between late September and November 25, 2010. Multiple owners say their vehicles fall within that build window and show identical symptoms, but their VINs were excluded from the recall and dealers refused to perform repairs. At least one owner also received notice of a faulty brake switch campaign recall. These are unverified consumer allegations; actual defect rates and root causes require investigation.
Failure modes owners describe
Rear Caliper Seizure
Rear brake calipers seize during driving, causing spongy brake pedal feel and loss of braking power. Multiple owners report the pedal traveling to the floorboard when applied. Seizure recurs shortly after replacement in at least one case.
When: 20,000 to 115,000 miles
Symptoms owners cite: Spongy or soft brake pedal; Brake pedal travels to floorboard; Reduced braking power; Calipers stick to rotors; No warning lights in some cases
Repairs/costs cited: Master cylinder, brake pads, and rear calipers require replacement. One owner replaced both calipers; caliper stuck again one month later, wearing brakes and rotor.
Recalls/TSBs owners mention: NHTSA Campaign 10V613000 (Service Brakes, Hydraulic) covers rear caliper failures on some 2011 Santa Fe models manufactured between late September and November 25, 2010. Multiple owners report their VINs were excluded from recall despite identical symptoms and manufacture dates within the recall window.
Brake Fluid Warning Indicator with Caliper Failure
Brake fluid warning light illuminates on instrument panel, later diagnosed as rear brake caliper failure requiring replacement.
When: 97,000 miles
Symptoms owners cite: Brake fluid warning indicator illuminates
Repairs/costs cited: Rear brake calipers require replacement.
Recalls/TSBs owners mention: NHTSA Campaign 10V613000; owner's VIN not included in campaign.
Brake Rotor Corrosion and Rust
Rotors corrode and rust excessively, leaving metal debris on garage floor, indicating accelerated corrosion failure.
When: 48,512 miles
Symptoms owners cite: Pieces of metal on garage floor; Rotor corrosion and rust
Repairs/costs cited: None reported; vehicle not repaired.
Recalls/TSBs owners mention: Manufacturer made aware; no action taken.
Abnormal Noise from Brake Area
Abnormal noise from passenger-side brake area during reversing, undiagnosed.
When: 74,759 miles
Symptoms owners cite: Abnormal noise from passenger side during reverse
Repairs/costs cited: Not diagnosed or repaired.
Faulty Brake Switch
Brake switch failure, with owner suspecting involvement in a crash. Dealer performed switch replacement under campaign recall.
When: Unknown
Symptoms owners cite: Suspected brake switch failure prior to crash
Repairs/costs cited: Brake switch replaced by dealer.
Recalls/TSBs owners mention: Campaign recall for faulty brake switch; owner notified by dealer and switch was replaced.
Sudden Unintended Acceleration with Brake Fade
Motor races at full throttle during low-speed parking maneuver with foot on brake pedal. Brakes fade under increased engine RPM. Engine continues racing after shifting to neutral with no foot on pedals. Resolved only by shutting engine off.
When: Unknown
Symptoms owners cite: Sudden unintended acceleration; Brake fade under motor RPM; Engine continues racing in neutral
Repairs/costs cited: None performed; vehicle started normally after incident.
Unintended Acceleration with Brake Failure Leading to Crash
Vehicle experienced unintended acceleration after brake pedal depression, resulting in crash into brick wall at 40,000 miles. Vehicle was destroyed. Prior repair under NHTSA Campaign 13V113000 (Exterior Lighting, Service Brakes, Hydraulic) had been completed.
When: 40,000 miles
Symptoms owners cite: Unintended acceleration after depressing brake pedal; Crash into obstacle
Repairs/costs cited: Vehicle destroyed; owner sustained air bag burns and neck injury requiring medical attention.
Recalls/TSBs owners mention: NHTSA Campaign 13V113000 (Exterior Lighting, Service Brakes, Hydraulic) completed prior to failure.
