What stands out
Owners have filed 28 powertrain 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.
No new NHTSA powertrain complaint has been filed on this vehicle in over 5 years — the issue may be aging out of the active population.
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
Owners consistently describe a transmission that slips, hesitates, and jerks, with most problems appearing between 31,000 and 85,000 miles. The car feels like it drops into neutral on acceleration, RPMs climb to 5,000–6,000 before shifting, and gears engage with rough, forcible jerks that can delay 5–30 seconds. Highway merging becomes dangerous when the transmission won't downshift fast enough.
The parking brake safety issue is severe: multiple owners report the transmission fails to hold the vehicle in park on inclines. Cars roll backward with repetitive banging and clicking while parked and unoccupied. The gear shift indicator frequently lies—showing park while the car acts as if it's in neutral. Owners resort to using the emergency brake as a workaround.
The shifter itself gets stuck between positions and sometimes won't move into park, reverse, or neutral at all. Engine stalling while driving at low speed has occurred without warning; the malfunction lamp illuminates only after the stall. One owner reported unexpected acceleration while inching into a garage.
Dealers acknowledge seeing this transmission problem and mention needing replacements, but no recall has been issued. Transmission shops find no error codes, and mechanics have been unable to fix the jerk and slip issues with fluid and filter changes alone. One owner's TCM connector loosening was traced and repaired, but this remains an isolated fix.

Failure modes owners describe
Transmission slipping and delayed/hesitant shifting
Transmission fails to shift smoothly or on time; owners report the car slips into neutral, RPMs climb without power delivery, or gear changes are delayed. Symptoms worsen as mileage accumulates and become more frequent.
When: 31,000 to 85,000 miles; some owners report onset around 25,000–40,000 miles; worsens over time and occurs during city driving, highway merging, and hill climbs
Symptoms owners cite: RPMs climb to 5,000–6,000 before transmission shifts; Transmission hesitates or jerks when shifting between gears, especially 2nd to 3rd; Vehicle feels as if it slips into neutral when accelerating, with no power reaching wheels; Delayed or absent downshift when accelerating to enter highway; Rough, forcible engagement when gear finally engages; 5–30 second delays before transmission responds
Codes mentioned: U0101 (TCM communication error, reported in one case after loose connector found)
Repairs/costs cited: Dealers diagnosed internal transmission failure and recommended or performed transmission replacement. Some owners report fluid and filter changes initially recommended but did not resolve the issue. Repair costs not specified in narratives.
Recalls/TSBs owners mention: No recalls or TSBs mentioned by Hyundai in the complaint narratives. One owner noted NHTSA Action DP21003 (Vehicle Speed Control) but dealer provided no assistance. Hyundai reportedly acknowledged seeing the issue (one dealer mentioned replacing transmissions in affected cars) but no formal recall issued.
Park/Neutral safety defect—transmission fails to hold vehicle in park
Transmission will not hold the vehicle in park on inclines or flat surfaces. Vehicle rolls away while parked and unoccupied, or rolls despite brake pedal engagement. Gear indicator does not match actual gear position.
When: On inclines or parked on driveways; affects low-mileage and higher-mileage vehicles
Symptoms owners cite: Vehicle rolls backward or forward while in park and unoccupied; Transmission makes repetitive banging and clicking sounds during rolling; Gear shift indicator displays park but vehicle behaves as though in neutral; Transmission fails to hold vehicle even with brake pedal depressed; Vehicle rolls despite being shifted to park multiple times
Repairs/costs cited: One owner reported dealer mentioned needing transmission replacement. Owners report having to use emergency brake as workaround to prevent rolling. One owner showed dealer the car rolled in park 2 out of 3 times on a slight incline.
Recalls/TSBs owners mention: Dealer acknowledged seeing this issue before and needing to replace transmissions; however, no official recall issued. Owners report this is an ongoing issue in 2007–2010 model years per online forums.
Gear shifter malfunction and misalignment
Gear shifter gets stuck between positions, requires force to move, and gear indicator on dash does not match actual transmission gear. Can fail to shift into park, reverse, or neutral.
When: Intermittent; affects vehicles at various mileages
Symptoms owners cite: Shifter becomes stuck and requires difficulty/force to move between positions; Gear indicator fails to register actual gear (e.g., dash shows park but car in neutral or drive); Unable to shift into park, reverse, or neutral; only drive shown on indicator; Intermittent failure—sometimes works correctly, sometimes does not
Codes mentioned: U0101 (loose TCM connector/pin issue identified in one case)
Repairs/costs cited: One owner had TCM reconnected at auto repair shop and shifter function returned to normal after pins and connectors were examined. No parts costs mentioned.
Engine stalling while driving
Engine cuts out unexpectedly during normal driving at low speeds with no warning signs until malfunction indicator lamp illuminates. Vehicle remains in gear but loses propulsion.
When: While coasting at slow speeds, not accelerating; reported at various mileages including 33,000 miles
Symptoms owners cite: Engine shuts off silently while driving at slow speeds; No jerking or noise before stall; Malfunction indicator lamp illuminates after stall; Complete loss of acceleration power; Electrical systems (lights, radio, fan) continue to operate; Engine restarts immediately when shifted to neutral and key cycled
Repairs/costs cited: One owner reported being given diagnostic fee estimate by dealer but did not proceed with diagnosis. Another owner disposed of vehicle because problem worsened. No repair costs specified.
Recalls/TSBs owners mention: Manufacturer contacted but no assistance provided in one case. Vehicle related to NHTSA DP21003 (Vehicle Speed Control) per one owner, but no manufacturer response documented.
Unexpected acceleration
Vehicle accelerates without driver input while maneuvering at low speed in parking or garage.
When: While inching into garage with foot off gas pedal
Symptoms owners cite: Sudden unexpected acceleration while foot not on gas pedal; Vehicle collided with garage wall before driver could brake
Transmission engagement jerking and hard shifts
Transmission engages with noticeable jerking or lurching motions, especially when shifting into reverse or during gear changes. Vehicle lunges forward when gears engage.
When: Intermittent; one case at 37,400 miles
Symptoms owners cite: Transmission jerks when shifting between gears; Hard, sudden jerky engagement when putting car in reverse; Vehicle lurches or lunges forward when shifting gears; Clunking noise during hard stops
Repairs/costs cited: One owner had transmission replaced at dealer. Another owner was misled by dealership sales representative (falsely told car had CVT transmission that 'always jerks'). Transmission shops found no diagnostic codes when scanning.
No-start condition with no clicking
Vehicle fails to start or make clicking noise when key is turned, suggesting electrical issue, but battery is not dead. Problem intermittent and resolves after repeated start attempts.
When: Intermittent; sometimes requires repeated on/off cycles before starting
Symptoms owners cite: No engine start on first key turn; No clicking noise from starter; Intermittent failure that eventually resolves after cycling key multiple times; No battery drain evident

What owners are reporting 2 most recent
Vehicle has 85,000 miles and the transmission slips in 2nd and 3rd gears. Does not matter if the weather is warm or cold or if engine is warm or cold. Reoccurring problem for several months.
December 4, 2021 while driving to San Diego, CA, interstate 8W, Hyundai started jerking and pulling very hesitant. I took the car to my mechanic on December 13th and he informed me that the transmission had a slippage problem! Shifting from 1st to 2nd and then again from 4th gear! Bottom line, I needed another Transmission! I called NHTSA at 888-327-4236 to report this issue, but only a written…
