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 describe a brake pedal that suddenly loses pressure and drops to the floor with no warning, leaving the vehicle unable to stop. One owner experienced this during normal turning and braking; the tow truck driver reproduced it on first attempt, yet two different dealerships could not verify the fault. Another owner reports the vehicle stalled without warning at 30,000 miles and refused to accelerate, accompanied by multiple dashboard warning lights and strange sounds.
The majority of complaints center on a recall issued in November 2020 for an electrical short in the ABS module creating a fire hazard. Hyundai instructed owners not to park vehicles indoors and told some to disconnect the battery and tow if the ABS light came on. The problem: the recall parts (a fuse kit and software update) remained unavailable for four months or longer. Owners report being told to call back in one to two weeks repeatedly, then learning parts wouldn't ship until Q1 or fall 2021. Dealerships placed owners on waiting lists with no clear completion dates.
Some owners experienced rear brake light circuit failures that recur even after bulb or harness replacement. Others report an emergency braking system that engages unpredictably, preventing acceleration—sometimes tied to door or seatbelt sensors, sometimes without clear cause.
The bulk of complaints are not about active brake failure but about recall handling: owners paying for cars they couldn't drive safely while waiting for unavailable parts, dealers prioritizing lot vehicles ahead of customer repairs, and Hyundai customer service unable to provide timelines or loaners.

Failure modes owners describe
Brake Pedal Loses Pressure / Drops to Floor
Brake pedal suddenly loses hydraulic pressure and sinks to the floor, rendering brakes inoperative. Occurs without warning during normal driving. Pressure sometimes returns after vehicle restart or after pump attempts.
When: At various speeds during normal driving; reported at around 30,000 miles in one instance
Symptoms owners cite: Brake pedal drops completely to floor with no resistance; Vehicle does not slow down or stop when brakes applied; Pedal remains flat even after multiple pump attempts; Pressure intermittently returns after vehicle shutdown/restart
Codes mentioned: 20V543000
Repairs/costs cited: Two dealerships unable to verify or diagnose the concern despite test drives and inspection lists. Issue reproducible by tow truck driver and owner but not replicated by dealer service.
Recalls/TSBs owners mention: No TSB or recall remedy documented for this specific symptom in the narratives; falls under NHTSA Campaign 20V543000 (Service Brakes, Hydraulic) but part availability was the stated barrier.
ABS System Electrical Short / Fire Hazard Recall (20V543000)
ABS module contains a corroded brake line or electrical short in the ABS system circuit that creates a fire hazard. Hyundai issued a safety recall requiring owners not to park vehicles indoors. Recall remedy involves installing a fuse kit and updating ABS software, but parts were chronically unavailable.
When: Recall issued November 2020; parts unavailable through at least Q1 2021 and beyond. Some owners report waiting from July 2020 onward.
Symptoms owners cite: ABS warning light may illuminate (per recall instructions if it comes on, disconnect battery and tow); Potential fire hazard from electrical short circuit; No actual brake failure reported by many owners under recall, but recall framed as urgent safety issue
Codes mentioned: 20V543000, Recall 195
Repairs/costs cited: Recall remedy: fuse kit installation and ABS software update. Parts backorder lasted 4+ months minimum; one dealer quoted availability in Q1 2021, another stated fall 2021. Multiple owners report dealer waiting lists with no clear timeframe.
Recalls/TSBs owners mention: Hyundai issued NHTSA Campaign 20V543000 (Service Brakes, Hydraulic) with fire hazard warning; parts distribution repeatedly failed; customer service offered loaner only if ABS light came on; case managers cited 3–5 business day response windows that did not materialize.
Rear Brake Light Circuit Failure
Rear brake light circuit intermittently fails to illuminate when brakes applied. Brake warning light on dash illuminates sporadically. Problem persists or recurs even after bulb replacement or harness repair by dealer.
When: Intermittent; occurs on and off without predictable pattern
Symptoms owners cite: Rear brake lights do not illuminate when pedal pressed; Brake warning light on dash comes on intermittently; Problem temporary after bulb replacement or harness repair, then recurs
Repairs/costs cited: Owner notes multiple solutions attempted: bulb replacement and harness replacement by dealership, neither providing permanent fix. Dealer refused to address issue on one vehicle because warning light did not appear during service visit.
Emergency Braking System Engages Unexpectedly / Vehicle Refuses to Accelerate
Vehicle's emergency or auto-braking system engages without driver command, causing vehicle to refuse acceleration. System trigger is inconsistent—sometimes door sensor, seatbelt sensor, or no clear cause. System remains engaged even when driver believes conditions (door closed, seatbelt fastened) are met.
When: Occurs at various times during normal driving and parking lot maneuvers
Symptoms owners cite: Alert in dashboard that emergency braking system has engaged; Vehicle refuses to accelerate despite driver input; Inconsistent trigger: sometimes door ajar sensor, sometimes seatbelt status, sometimes no clear cause; System may engage when driver is backing out and hasn't fastened seatbelt yet
Vehicle Stall and Loss of Acceleration with Multiple Warning Lights
Vehicle stalls and fails to accelerate while pedal is depressed. Multiple unknown warning lights intermittently illuminate. No single warning light consistently illuminated beforehand.
When: Approximately 30,000 miles
Symptoms owners cite: Vehicle stalls while driving; Fails to accelerate despite accelerator pedal depression; No warning light illuminated before failure; Multiple unknown warning lights intermittently illuminate during issue; Vehicle jerks forward; Abnormal odor and abnormal sound from vehicle
Codes mentioned: 20V543000
Repairs/costs cited: Vehicle diagnosed at owner's expense at local dealer; warranty deemed invalid; vehicle not repaired. Owner relates failure to NHTSA Campaign 20V543000.
Recalls/TSBs owners mention: Manufacturer was made aware; no remedy documented in narrative.
