What stands out
Owners have filed 31 brakes complaints with NHTSA against this vehicle, but no formal recall covers the issue — the federal record reflects what manufacturers have admitted, not everything owners are reporting.
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 bulletin describes the procedure to inspect and identify fluid which may appear around the brake caliper area.

The failure pattern owners describe
Owners of the 2011 Elantra describe serious, recurring brake problems. Brake lines corrode prematurely due to underbody coating failure, causing fluid leaks and total loss of braking at highway speeds. One owner lost all brakes at 30 mph and hit a stop sign; another crashed at 45 mph with a destroyed vehicle and back injury.
Rear brake pads separate from backing plates and wear drastically faster than front pads—one owner's pads deteriorated between 3,500-mile service intervals despite conservative driving. Rear rotors rust and seize internally. The issue is unusual on a front-wheel-drive vehicle, and Hyundai dealerships recommend 15K-mile rear brake lubrication as preventive maintenance, suggesting the manufacturer acknowledges a systemic problem.
Brake pedal problems occur at idle, especially when the A/C compressor cycles. The pedal sinks gradually or loses pressure, causing the car to creep forward while stopped. In severe cases, the pedal goes to the floor with zero stopping power.
Vacuum brake boosters fail from internal rot and perforation. The ABS control module has an electrical issue that can cause internal brake fluid leaks and engine compartment fire—a major recall (NHTSA Campaign 23V651000) was issued, but parts remain unavailable years later. One owner disconnected the battery due to fire risk.
Braking feels violent and jerky, and the vehicle pulls sharply to one side during stops. One owner noted a brake light switch failure preventing brake lights from illuminating.

Failure modes owners describe
Brake Line Corrosion/Failure
Brake lines rust out due to premature underbody coating failure, causing loss of brake fluid pressure and complete brake system failure. Owners report rust-compromised lines no longer holding fluid.
When: Variable mileage; one complaint at 30+ mph, one at unknown mileage
Symptoms owners cite: Loss of brake fluid; Brake pedal goes to floor with no braking; Visible brake fluid leaking from underbody; Brake lines completely rusty
Repairs/costs cited: Brake line replacement needed; one owner used hand brake to limp home after failure
Recalls/TSBs owners mention: NHTSA Campaign 23V651000 (Service Brakes, Hydraulic); underbody coating recall issued but no brake line replacement mentioned. Parts availability delayed on recall.
Rear Brake Pad/Rotor Premature Wear and Rust
Rear brake pads separate from backing plates and deteriorate prematurely despite conservative driving. Rear rotors rust internally and externally. Issue occurs much earlier than typical wear rates and disproportionately affects rear brakes on a FWD vehicle.
When: 3,500 miles between inspections (one case), 50,000 miles (highway driving), 1,300 miles in two years of storage
Symptoms owners cite: Inner rear pads flapping/separating from backing plates; Rear brake drag; Rear rotor rust and corrosion; Rear rotors require resurfacing or replacement
Repairs/costs cited: Rear pads and rotors replaced; dealers recommend rear brake lubrication at 15K miles as preventive maintenance (unusual for FWD vehicles)
Recalls/TSBs owners mention: Hyundai dealership recommends 15K-mile rear brake lubrication to avoid caliper/pad/rotor issues; not a formal recall or TSB in narratives
Brake Booster Failure (Vacuum-Assisted)
Vacuum brake booster canister fails due to internal rot and perforation, causing sudden loss of brake boost and brake pressure.
When: Unknown mileage
Symptoms owners cite: Brake booster canister rot; Brake perforation; Loss of power braking
Repairs/costs cited: Not specified in narrative
Brake Pedal Sinking/Loss of Pressure at Idle
Brake pedal gradually sinks or loses firmness while vehicle is stopped, especially when A/C compressor cycles on/off at idle. Pedal may travel to floor with no braking response. Brake pressure increases over several seconds of holding pedal down.
When: At stop lights/idle, particularly with A/C compressor cycling in summer
Symptoms owners cite: Brake pedal becomes soft or sinks when A/C cycles; Pedal creeps down over 5-10 seconds at idle; Vehicle slowly moves forward despite brake pressure; Brake pedal eventually reaches floor
Repairs/costs cited: Not specified
Complete Brake Failure During Driving
Brakes fail entirely while vehicle is moving, causing loss of all stopping power. Brake pedal goes completely to floor with no response. Owners involved in collisions unable to stop despite emergency braking effort.
When: At 10 mph in traffic (one crash), 30 mph at intersection (one failure), 33,000 miles (crash), 45 mph during deceleration (crash)
Symptoms owners cite: Brake pedal to floor with no stopping power; No brake response despite full pedal pressure; Brake fluid visible leaking at bottom of vehicle
Repairs/costs cited: One vehicle destroyed in crash; another used hand brake to limp home; crash victim sustained back injuries
Brake Pedal Soft/Spongy or Collapsing Sensation
Brake pedal feels soft, spongy, or develops a collapsing sensation under pressure. Pedal may not feel firm during normal stops and operator may need to apply excessive force.
When: Variable; one at 17K miles (dealership notice), ongoing issues reported
Symptoms owners cite: Brake pedal feels soft or spongy; Pedal develops abnormal give or collapse sensation; Excessive pressure required to stop vehicle
Repairs/costs cited: One owner replaced master cylinder but issue persisted; attributed to ABS system interference
ABS System Electrical Failure/Fire Risk
ABS control module or electrical system fails, creating risk of internal brake fluid leak and electrical short. Potential for engine compartment fire while parked or driving.
When: Unknown mileage; ABS warning light illuminated since vehicle ownership in one case
Symptoms owners cite: ABS warning light illuminated on dashboard; Abnormal noise from rear during driving; Vehicle stalling upon accelerator depression; Smoking from vehicle
Codes mentioned: ABS warning light
Repairs/costs cited: Not repaired in narratives; one owner disconnected battery due to fire risk
Recalls/TSBs owners mention: NHTSA Campaign 23V651000 (Service Brakes, Hydraulic) addresses ABS module leak and fire risk. Parts not yet available at time of complaints. Owners advised vehicle can still be driven but should not be parked near buildings.
Brake System Uneven or Pulling Behavior
Brakes cause vehicle to jerk violently or pull sharply to one side (usually right) when engaged. Vehicle dips and pulls into adjacent lane during hard braking.
When: At various speeds during normal driving and emergency stops
Symptoms owners cite: Violent jerking when brakes engaged; Abnormal noise when brake pedal depressed; Vehicle pulls sharply to right during braking; Vehicle dips and changes lanes during emergency stop
Repairs/costs cited: Dealer unable to diagnose; one owner told to avoid quick stops
Brake Light Switch Failure
Brake light switch fails to function, preventing brake lights from illuminating when brakes are applied.
When: Unknown mileage
Symptoms owners cite: Brake lights do not illuminate when brakes applied
Repairs/costs cited: Not specified
