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
The dominant issue across these 34 complaints is NHTSA recall 20V543000 for a defective ABS hydraulic control unit (HECU) that corrodes internally, causing electrical shorts and engine compartment fires. Most complaints—roughly 20 of them—simply report receiving the recall notice and finding parts unavailable at their dealership for extended periods. Owners were told to park vehicles outside their garages because fire risk exists even when the engine is off. Hyundai offered at least one buyback after a vehicle actually caught fire and was totaled.
Beyond the recall, owners report unrelated brake issues: brake light bulbs overheating and burning out repeatedly (driver's side and passenger's side both failing multiple times within weeks or months), with lead solder melting on the bulbs themselves. One owner mentions an unusually hard brake pedal when parked, preventing engine start until significant pressure is applied. Others describe actual brake failures—a pad breaking apart and causing loss of ABS function, brakes seizing at low speeds with grinding noise, and one accident where the pedal went to the floor and ABS did not engage. An ABS sensor and harness assembly also failed on at least one vehicle, with the dealer unable to source the replacement part.
The core frustration across complaints is parts scarcity: multiple owners report calling dealerships repeatedly over months with no resolution or estimated arrival date for recall repair parts.

Failure modes owners describe
ABS Module Corrosion & Electrical Short (HECU Defect)
The HECU (Hydraulic Electronic Control Unit) in the ABS system corrodes internally, causing wires to short and creating a fire risk in the engine compartment. Owners report being advised not to park vehicles in garages due to fire danger even when the vehicle is not running.
When: Reported across mileage range 19,000–100,000 miles; recall issued December 2020 and later
Symptoms owners cite: Burning odor while driving; White smoke from engine; ABS warning light illumination; Check engine light illumination; All warning lights illuminating together; Vehicle stalling; Engine compartment fire (in extreme cases)
Codes mentioned: NHTSA Campaign Number 20V543000 (Service Brakes, Hydraulic)
Repairs/costs cited: HECU replacement required; parts unavailable at time of reporting for most owners. One owner had engine replaced due to fire damage.
Recalls/TSBs owners mention: NHTSA Campaign 20V543000 issued; Hyundai offered buyback on at least one totaled vehicle; advised some owners to park outside and check for leaks; scheduled repairs delayed due to parts shortage
Brake Light Bulb Overheating & Premature Failure
Brake light bulbs on both sides of the vehicle burn out repeatedly in short intervals, with the bulbs overheating to the point of melting the lead solder. Auto parts stores report similar complaints from other Hyundai owners.
When: Reported starting late 2019 (bulbs failing within weeks to months of replacement)
Symptoms owners cite: Brake light bulb burnout on driver side; Brake light bulb burnout on passenger side; Bulbs overheating and melting lead; Repeated bulb failures (driver side failed multiple times, passenger side failed at least three times)
Repairs/costs cited: Bulb replacement attempted; suspect wiring harness issue noted by owner. Independent mechanic inspection was planned.
Hard Brake Pedal & Starting Difficulty
Brake pedal becomes very hard (rock solid) when vehicle is stationary, requiring excessive force to press for engine start via smart key procedure. If the brake pedal press is not detected, the engine will not start and the ignition stays in ACC or ON position.
When: Reported January 24, 2019
Symptoms owners cite: Brake pedal extremely hard/stiff when parked; Difficulty starting engine due to brake pedal resistance; Engine start failure until brake pedal is pressed with sufficient force; Ignition switch stuck in ACC or ON position
Repairs/costs cited: Dealership inspection scheduled for February 15, 2019 (significant delay from report date January 25)
ABS Sensor & Harness Failure
ABS sensor and tail harness/lamp assembly failures causing warning light illumination. Dealer diagnosed the need for replacement but parts were unavailable.
When: Reported at 28,223 miles
Symptoms owners cite: ABS warning light illumination while driving at 30 MPH
Repairs/costs cited: Tail harness, lamp assembly, and ABS sensor replacement needed; dealer awaiting parts arrival
Recalls/TSBs owners mention: Manufacturer notified
Brake Seizure & Grinding Noise
Brakes seize at low speeds accompanied by abnormal grinding noise. Issue resolves after vehicle is turned off and restarted.
When: Reported at 94,050 miles
Symptoms owners cite: Brakes seize at low speeds; Abnormal grinding noise during brake application
Repairs/costs cited: Vehicle not diagnosed or repaired
Brake Failure Under Load
Complete brake failure during driving, with pedal going to the floor and ABS not engaging, causing brake lockup and collision.
When: Reported at undisclosed mileage; one accident at 24,919 miles with undiagnosed brake failure
Symptoms owners cite: Brakes failed to work as intended; Brake pedal to the floor; ABS did not engage; Brakes locked up; Collision resulting from brake failure
Repairs/costs cited: One vehicle diagnosed but cause not determined; one vehicle not diagnosed
ABS Pad Breakage & Loss of ABS Function
ABS brake pad broke and separated from the caliper assembly, causing squealing noise and complete loss of ABS function.
When: Reported at undisclosed mileage
Symptoms owners cite: ABS sticking; ABS brake pad broke off; Squealing noise during driving; Metal debris found under vehicle; ABS brakes no longer functional
Repairs/costs cited: ABS brake pad replacement needed; repairs not yet completed
