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 2016 Sonata brake complaints fall into three main groups: spontaneous emergency braking, brake system failures, and ABS/sensor malfunctions.
Spontaneous emergency braking strikes without warning at speeds from 30 to 55 mph. Owners describe abrupt stops with no objects in the road ahead, no dashboard warnings, and sometimes a beep sound. One owner's vehicle braked so hard at highway speed the rear wheels locked up and caught fire. A forward collision warning system is oversensitive in normal traffic, triggering hard stops and nearly causing rear-end collisions. Owners report disabling the feature because it's unsafe in busy traffic.
Brake failures range from complete loss of stopping power to soft pedals requiring heavy pumping. One vehicle lost all brakes at 30 mph on a highway, forcing the driver to use the emergency brake; another caught fire after rear brakes locked up while accelerating. Several owners report brake pedals that feel sluggish or won't engage until released and reapplied. Dealers struggle to diagnose these—some replace the entire ABS system with no record, install new brake lines, or swap calipers without resolving the issue.
ABS and sensor problems generate warning lights for ABS, traction control, and brake system faults. Owners report rear brake calipers seizing, wheels locking at highway speed, and sensor diagnostics failing to read codes. Some vehicles show impossible sensor readings (rear wheels at 200 km/h while idle). Pressure source units and rear bearing sensors were replaced at dealership cost ranging from $1,500 to $4,000. One vehicle exhibited the brake failure at 5,000 miles on its first three months of ownership.
Hyundai issued a manufacturer campaign (TFF 2016 Sonata Electric Parking Brake Logic Update) after at least one incident, but owners report the company did not proactively notify buyers of the danger.

Failure modes owners describe
Spontaneous emergency braking
Automatic emergency braking system (AEB) engages without warning, bringing vehicle to an abrupt stop on clear roads at speeds ranging from 30–55 mph, with no dashboard warning and sometimes a beep sound. One incident involved rear wheels locking and catching fire. Forward collision protection system also triggers inappropriately during normal traffic braking.
When: Occurred at various mileages, one incident at 4,500 miles (3 months of ownership); another at 2,769 miles
Symptoms owners cite: Sudden vehicle stop with no obstruction ahead; No dashboard warning lights before event; Beeping sound sometimes present; High-pitched tone during AEB engagement; AEB system indicator illuminates after activation; Rear wheels locking up and heating to dangerous temperatures; Smoke and fire from overheated rear brakes
Repairs/costs cited: Dealerships tested vehicles overnight and found no defect; manufacturer issued campaign TFF 2016 Sonata Electric Parking Brake Logic Update after incidents
Recalls/TSBs owners mention: Manufacturer campaign TFF 2016 Sonata Electric Parking Brake Logic Update issued; however, owners report Hyundai did not proactively notify buyers of danger. Corporate denied claims when testing showed no defect.
Complete brake failure
Total loss of braking function while driving at highway or suburban speeds, forcing drivers to coast to stop or use emergency brake. One vehicle braked at 30 mph with no stopping power and caught fire. Another lost brakes at 30 mph on a highway. Brake pedals sometimes become unresponsive or mushy before total failure.
When: One incident at 5,000 miles (less than 3 months old); another at 91,000 miles; 30–40 mph speeds reported
Symptoms owners cite: Complete loss of braking power mid-drive; Vehicle unable to decelerate; Brake pedal unresponsive or extremely hard to press; Smoke and fire from engine/brake system; No warning lights before failure; Driver forced to use emergency brake to stop vehicle
Repairs/costs cited: One vehicle destroyed by fire; another coasted to 5 mph and stopped via forced emergency braking. Fire department responded to engine fire.
Brake booster failure
Brake booster requires replacement; vehicle unsafe to drive. Multiple dealers identified the need for brake booster replacement, but repairs were not completed. Contributes to soft or unresponsive brake pedal.
When: One reported at approximately 154,000 miles
Symptoms owners cite: Vehicle unsafe to drive per dealer assessment; Soft brake pedal; Brake booster malfunction
Repairs/costs cited: Independent mechanic and dealer both identified brake booster needing replacement; repairs not completed
Soft or intermittent brake pedal
Brake pedal feels soft or requires multiple pumps to fully engage, or refuses to engage until released and re-applied. Some vehicles exhibit sluggish braking (feeling like the parking brake is on) despite no warning lights. Owners report nearly avoiding accidents due to inability to stop quickly.
When: Reported across various mileages; one case at 62,000 miles over 4 months of service attempts
Symptoms owners cite: Soft brake pedal requiring multiple pumps; Pedal gives resistance and won't fully engage until released and pressed again; Sluggish braking sensation (parking brake-like feel); Vehicle lurches while braking; Steering wheel shakes after braking above 45 mph; Uneven rear brake application; No warning lights
Repairs/costs cited: Dealers replaced entire ABS system (with no record), installed new brake lines, and replaced calipers without resolving issue. One vehicle kept at dealership for 4 months with no successful resolution.
Rear brake caliper seizure
Rear brake caliper locks up without driver input, sometimes repeatedly, causing wheel lock-up and dragging of vehicle. Occurred at very low mileage on a new vehicle. No warning lights present.
When: At 8,020 miles (near-new vehicle); occurred three times before final lock-up incident on 4/8/2019
Symptoms owners cite: Right rear brake caliper seized; Rear wheel locked up during forward motion at 30 mph; Vehicle dragged with three tires spinning; No warning indicator lights; Caliper self-corrected initially, then permanently seized
Repairs/costs cited: New rear brake caliper installed; diagnostic codes could not be read by dealer
Recalls/TSBs owners mention: Manufacturer was notified of failure
ABS and sensor malfunction
ABS system failures accompanied by erroneous sensor readings or non-responsive diagnostics. Symptoms include illuminated ABS, traction control, and TPMS warning lights. Diagnostic equipment sometimes fails to read fault codes. One instance showed rear wheels reading over 200 km/h while vehicle was idle—an impossible reading indicating sensor or module failure.
When: One reported at 50,000 miles; another at under 40,000 miles and recurring at 79,000 miles
Symptoms owners cite: ABS light illuminated; Traction control light illuminated; TPMS warning light illuminated; Brake system warning lights; Diagnostic equipment unable to read codes; Erroneous sensor readings (rear wheels at 200 km/h while idle); ABS system failure diagnosed but not repaired
Codes mentioned: P1326 (reported in one complaint involving engine/oil issue, but listed alongside brake complaints)
Repairs/costs cited: Pressure source unit replacement costs $1,500–$4,000; rear bearing sensors $1,500; ABS control module replacement; new brake lines. One dealership overcharged ($289/hr labor vs. $190 at competing dealer; $2,159 for pressure source unit vs. $1,900 elsewhere).
Recalls/TSBs owners mention: Hyundai campaign TFF 2016 Sonata Electric Parking Brake Logic Update; one owner received no response from manufacturer regarding ABS module failure
Electric parking brake unintended engagement
Electronic parking brake activates suddenly while vehicle is moving at speed, locking rear wheels without driver input. Occurs at highway speeds (over 55 mph) and causes severe braking, wheel lock, and potential fire hazard.
When: One incident at over 55 mph acceleration; vehicle had 5,002 miles and was 3 months old at time of incident (purchased 3/5/2016, occurred before 8/23/2016)
Symptoms owners cite: Electronic parking brake activates without warning at speed; Violent brake system pulsing; Rear wheels lock completely while vehicle accelerating; Wheels too hot to touch; Smoke/fire risk from overheated brakes; No warning lights before activation; Multiple sensor systems failed simultaneously
Repairs/costs cited: Entire rear braking system destroyed; owner had to pour water on brakes to prevent fire
Recalls/TSBs owners mention: Hyundai issued manufacturer campaign TFF 2016 Sonata Electric Parking Brake Logic Update; company claims redundant sensors and check sensors should prevent such failure; Hyundai did not proactively alert owners to the danger
Brake pedal positioning/interference hazard
Fuse box mounted above gas and brake pedals sits too close, causing foot to occasionally brush it during normal pedal operation, creating split-second delay in transitioning from accelerator to brake.
When: Ongoing hazard during normal driving
Symptoms owners cite: Foot brushes fuse box while operating pedals; Split-second delay transitioning from gas to brake; Unsafe for drivers with shoe size 10.5 (reported by owner)
Repairs/costs cited: Service dealer stated nothing can be done; owner notes 2011 Sonata model had better foot room
Brake warning light failures / missing indicators
Safety-critical brake system failures occur without any dashboard warning lights illuminating beforehand, leaving drivers unaware of dangerous conditions. One owner reported uneven brake application with no lights.
When: Across multiple incidents from 5,000 miles to 154,000 miles
Symptoms owners cite: No brake warning lights before system failure; No ABS light, traction control light, or check engine light despite serious brake malfunction; No indicator lights for parking brake engagement (Hybrid model); Uneven rear brake application with no warning
