Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering powertrain 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.
The automatic transmission warranty repair policy authorizes in-dealership repairs of the following components for both OEM (new) and remanufactured automatic transmissions:

The failure pattern owners describe
The 2010 Sonata's powertrain generates a broad list of complaints centered on transmission behavior and shifter control. Shift lock failures are prominent: owners report vehicles shifting out of Park without brake pedal depression, vehicles refusing to shift into Park, and inability to remove the ignition key when the shifter won't engage. One owner had recall #13V113000 performed—which addressed the stop lamp switch via OEM part 93810-4DR0A-QQH—yet the vehicle continued to shift out of Park without braking; Hyundai refused further warranty work due to vehicle age.
Manual transmission owners report stalling when disengaging the clutch from Reverse and First gear, along with clacking, squealing, or burning smells when trying to move forward. One clutch pedal sticks to the floor repeatedly, requiring a fourth master cylinder replacement with no explanation from the dealer.
Automatic transmission jerking is widespread. Owners describe abrupt downshifts at 20 MPH when cold, heavy jerking during braking, and daily jerking that persists across multiple dealer visits and transmission updates. One owner notes the dealer mentioned the vehicle may need a new transmission. Unintended acceleration also appears: vehicles lurch forward during shifts with minimal throttle input, accelerate in Reverse without pedal input, and lose power or exhibit loss-of-hold on inclines in Drive.
Dealer diagnosis is inconsistent—many shops cannot duplicate the failures or offer no root cause. Check Engine lights come and go without lasting resolution.

Failure modes owners describe
Shift Lock / Shifter Interlock Malfunction
Vehicle will not shift into Park or shifts out of Park without brake pedal depression. One owner reports recall #13V113000 was performed but the vehicle still shifts out of Park without braking. Another reports inability to shift into Park and key removal blocked unless shift lock button is manually overridden.
When: 3,500 miles to 90,640 miles
Symptoms owners cite: Vehicle shifts out of Park without brake pedal depression; Vehicle will not shift into Park; Key cannot be removed from ignition when shifter is not in Park; Vehicle rolls down incline when left in Drive with key removed
Repairs/costs cited: Recall #13V113000 replacement of stop lamp switch (OEM part 93810-4DR0A-QQH) did not resolve the issue in at least one case. Manual shift lock button override required in another case.
Recalls/TSBs owners mention: Recall #13V113000 performed; manufacturer refused further warranty service on vehicle over 10 years old, citing vehicle age.
Transmission Jerking / Harsh Downshift
Owners report abrupt, heavy jerking during downshift, particularly when cold or during deceleration. One owner attributes the issue to older model computer control equipment installed in 2010 Sonatas causing communication failure between transmission control module and solenoid.
When: As early as 809 miles; recurring at 20 MPH when cold; at 65,000 miles reported on daily basis
Symptoms owners cite: Abrupt downshift causing jerking motion when decelerating through 20 MPH in cold conditions; Harsh downshift when stopping or slowing down; Heavy jerking on daily basis; Check Engine light may appear initially then disappear while jerking persists
Codes mentioned: Check Engine light (lit then cleared)
Repairs/costs cited: One owner reports dealer reset computer control values and mentioned vehicle may need new transmission; not repaired.
Recalls/TSBs owners mention: Unknown recall for this issue per one owner's research; transmission updates performed on at least one vehicle without resolving failure.
Manual Transmission Stalling and Engagement Issues
Manual transmission stalls when disengaging clutch from reverse and first gear. Vehicle requires clutch dragging and aggressive accelerator use to move. Abnormal noises accompany the problem.
When: Since purchase at 809 miles; recurring at 1,794 miles
Symptoms owners cite: Stalling when disengaging clutch from Reverse and First gear; Clacking noise in front of car when dragging clutch to move vehicle; Squealing or rubbing sound with burning smell; Vehicle lurches forward during shift from First to Second gear with minimal throttle input
Repairs/costs cited: Dealer unable to duplicate the complaint despite two visits.
Transmission Shift Refusal and Stuck Shifter
Shifter becomes unresponsive and requires manual engagement of shift release mechanism to operate. Transmission fails to shift gears in some cases.
When: 88,000 miles and at 16,500 miles
Symptoms owners cite: Shifter requires engagement of shift release to operate; Transmission fails to shift gears; Check Engine light illuminated; Vehicle stalling
Codes mentioned: Check Engine light
Repairs/costs cited: Dealer unable to diagnose root cause.
Recalls/TSBs owners mention: Manufacturer notified; no assistance offered.
Clutch Pedal Sticking and Transmission Resistance
Clutch pedal goes to floor and becomes stuck, making gear changes difficult. Requires repeated replacement of master cylinder.
When: First failure at 8,000 miles; current mileage 67,000
Symptoms owners cite: Clutch pedal goes to floor; Clutch pedal stuck; Vehicle resistant when changing gears
Repairs/costs cited: Master cylinder replacement scheduled for fourth time; dealer provided no explanation for repeated failures.
Acceleration Delay / Transmission Control Module Programming
Transmission exhibits 2-3 second lag when shifting from 1st to 2nd gear. Suspected cause is transmission control module programming.
When: Not specified
Symptoms owners cite: 2-3 second delay in acceleration; Delays when shifting from 1st to 2nd gear
Vehicle Rollback on Incline in Drive
Vehicle rolls backward on inclines when in Drive. One owner describes freefall motion in the time it takes to move foot from brake to accelerator.
When: Not specified
Symptoms owners cite: Vehicle rolls backward on incline when in Drive; Loss of holding power during brake-to-accelerator transition
Repairs/costs cited: Dealer told owner this is how vehicle is designed.
Transmission Shake and Severe Vibration
Vehicle shakes violently when shifting from Park to Reverse. Instrument cluster gauges do not display readings during event.
When: At 30,000 miles
Symptoms owners cite: Violent shaking when shifting from Park to Reverse; Instrument gauges fail to display readings; Difficulty starting vehicle (takes several attempts)
Repairs/costs cited: Transmission updates performed four times; failure persisted.
Unintended Acceleration / Loss of Throttle Control
Vehicle accelerates without driver input or lurches forward unexpectedly during gear changes and maneuvers.
When: Not specified in most cases; one at 28,000 miles
Symptoms owners cite: Vehicle lurches forward during downshift with minimal throttle input; Vehicle accelerates without foot on gas pedal; Vehicle suddenly accelerates in reverse; Vehicle will not accelerate beyond 50 MPH then stalls; Violent jerking forward when depressing brake pedal to slow down
Repairs/costs cited: One owner advised transmission replacement needed; no repairs performed. One owner's computer reset with no lasting resolution.
