This bulletin provides information related to a Transmission Control Unit (TCU) software update for some vehicles equipped with an 8-speed wet dual clutch transmission (8WDCT). The software update revises the touch point learning variation, improving drivability and judder symptoms. Some 8WDCTs (indicated by a new part number) received an updated clutch spring. The correct TCU software update must be matched with the correct corresponding 8WDCT hardware, otherwise, drivability concerns may occur. This service procedure should be performed prior to any 8WDCT replacements done for drivability/judder concerns.

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.
Some Santa Cruz (NXT), Santa Fe (TMA, MX5A), and Sonata (DN8A) models may require replacement of the 8-speed wet dual clutch transmission (8WDCT) when the vehicle sets one of the high pressure electric oil pump (HP EOP) DTCs listed below. This bulletin provides instructions to replace the 8WDCT.

The failure pattern owners describe
The 2022 Sonata is generating 22 powertrain complaints centered on transmission behavior and engine management. Owners report hard shifting on upshifts and downshifts, sometimes with physical jolts at 4-5K RPM; first-gear stutter that persists even after dealers claim to have performed a 2023 recall fix. Several owners describe complete loss of drive power while accelerating on highways or at traffic lights—the vehicle simply stops responding to the pedal and engine shuts down, forcing a restart or shift-to-Park cycle to restore function. One case involved a collision.
Shifter malfunction warnings prevent gear selection, immobilizing the car at intersections. Owners experience intermittent stalling without warning lights and hesitation during transmission shifts. Engine overheating warnings appear randomly and resolve seconds later; one hybrid owner at 83k miles faced a failed antifreeze valve ($2,659 out of warranty). Recall 22V746000 was issued for transmission oil pump problems, but many owner VINs fall outside the recall scope and parts remain on national backorder. Dealerships consistently cannot replicate these faults or reproduce them in diagnostics. One owner waited five months for a service appointment while the vehicle still exhibited the original symptom.

Failure modes owners describe
Transmission stutter and jerking on first-gear engagement
After transmission reprogramming recall (early 2023), owners report the vehicle still exhibits shuddering and hard shifting in first gear and upshifts. One owner's recall shows as repaired in the system despite ongoing symptoms.
When: Within 1 month of purchase (May 2022); recurring after July 2022 and through service attempts
Symptoms owners cite: First gear stutter; Jerking on upshift; Hard shifting to second gear from first
Repairs/costs cited: Dealership performed transmission reprogramming as recall fix; second owner (with 25k miles) reports hard shifting continues despite in-warranty status
Recalls/TSBs owners mention: Transmission recall addressed via reprogramming; parts remain on national backorder for some repairs
Delayed gear engagement and hard shift slam under downshift
When owner downshifted to slow descent, gear indicator showed 2nd but vehicle remained in higher gear. After 1-2 seconds, transmission slammed hard into target gear with engine revving to 4-5K RPM, physically jolting occupants. Transmission felt rough for weeks before and after incident.
When: After weeks of noticeably rough shifting
Symptoms owners cite: Delayed gear engagement after downshift command; Hard slam into gear; Unexpected high RPM rev-up; Rough shifting at low speeds in all gears except 4th
Repairs/costs cited: Owner unable to schedule dealership inspection (2+ month wait)
Complete loss of drive power while accelerating
Engine shuts down or transmission loses power while vehicle is in motion (highway passing, parking lot exit, intersection), no warning lights. Owners must shift to Park and back to Drive or restart engine to restore power. Some incidents tied to recall 22V746000 (transmission oil pump malfunction fail-safe mode).
When: Intermittent; one owner reports late 2022 and again 8/15/23; another on highway at 70 mph; another at intersection
Symptoms owners cite: No acceleration response despite pedal input; Engine shutdown or loss of drive power; Vehicle slows or stops in traffic; No tachometer response
Codes mentioned: 22V746000
Repairs/costs cited: Requires shutdown/restart or shift to Park then Drive to restore function
Recalls/TSBs owners mention: Recall 22V746000 issued for transmission oil pump malfunction; however, some owner VINs not included in recall scope
Shifter system malfunction preventing gear selection
Dashboard warning 'Shifter system malfunction service immediately' appears, preventing driver from shifting out of current gear. Vehicle becomes immobilized at traffic lights and intersections until engine is restarted multiple times. Error clears after restart.
When: Occurred 10+ times within one month period
Symptoms owners cite: Unable to shift out of gear; Dashboard warning message; Immobilization at traffic light
Codes mentioned: Shifter system malfunction
Repairs/costs cited: Dealership replaced Transmission shifter module (TCM) at no cost to owner under dealer warranty coverage (Hyundai declined coverage but dealership paid)
Recalls/TSBs owners mention: Hyundai declined to cover under warranty; dealership paid for repair out of goodwill

Automatic transmission hesitates or hesitation when shifting. Vehicle loses power and stalls completely in middle of traffic maneuver without warning. Dealership cannot replicate. Owner reports open recall on same make/model but VIN not included.
When: Multiple occasions; complete stall while turning
Symptoms owners cite: Acceleration hesitation; Transmission shift lag; Complete engine shutdown while driving; No warning lights
Repairs/costs cited: Dealership unable to replicate; no repairs performed
Recalls/TSBs owners mention: Recall on same model exists but owner's VIN not included; Hyundai case manager unable to resolve
Engine overheating and limp mode triggering
Dashboard displays engine overheating warning; vehicle enters limp mode and limits power. Within seconds, warning clears and vehicle resumes normal operation. Also occurs with intermittent ITMS (Integrated Transmission Management System) failures showing false overtemp alerts. One case involved antifreeze valve failure causing white smoke from exhaust and actual overheating risk.
When: Intermittent; ITMS failures occurred 5+ times; white smoke incident at 83k miles on hybrid
Symptoms owners cite: Engine overheating warning on dash; Limp mode activation; Loss of acceleration during warning state; False overtemp alerts; White smoke from exhaust (hybrid); High oil temperature; Constant fan operation

Recalls/TSBs owners mention: Recall repair parts on backorder; dealer unable to diagnose ITMS issues despite multiple service visits and service records from other owners
Hard shifting and rough transmission engagement
Transmission shifts noticeably rough during normal driving, particularly on upshifts and downshifts at low speeds. Hard downshift on deceleration more pronounced than hard upshift.
When: Ongoing; vehicle with 25k miles still in warranty
Symptoms owners cite: Hard upshift from 1st to 2nd gear; Hard downshift when slowing; Rough shifting in all gears below 4th
Air conditioning intermittent failure
AC stops working randomly. In one case, vehicle shut down completely while owner was driving and had to be towed. Dealership initially blamed fuel injector, then claimed fuel pump failure. After repair and return, same symptoms (no AC, failure to start) recurred within 8 hours. Dealership unable to diagnose root cause; attempted to blame external factors (smell from old gas can). Problem persists on intermittent basis.
When: Last month of narrative; recurring after dealership service
Symptoms owners cite: AC stops working randomly; Vehicle shutdown while driving; Vehicle won't turn over after shutdown; No AC operation
Repairs/costs cited: Dealership performed fuel pump replacement; problem not resolved. No diagnosis provided on paperwork.

Shifter system malfunction service immediately was displayed on my dash 10+ times which caused me to not be able to shift my car out of drive or whatever gear I was in when this occurred. I was at an intersection and when I was coming to a stop the car displayed this error code and wouldn’t allow me to go until I turned the car off and on twice till it was able to reset back to park then…
Car sometimes does not accelerate appropriately. Car needs to be shut off and restarted when this happens. Dealerships around me say they don’t see anything wrong with the car. It happens randomly and shouldn’t happen with a brand new car. I feel unsafe when it doesn’t accelerate correctly.
When driving down a hill, I downshifted to slow my descent and to not have to use the brakes as much. I downshifted once or twice making sure the engine didn't go far above 3000 RPM. The gear indicator showed 2nd gear but I knew that wasn't accurate because the car had yet to change gear and the RPM was too low for 2nd gear, I was still in 3rd or 4th gear. About a second or two goes by until the…
On multiple occasions, the car has intermittent acceleration issues and hesitates when the automatic transmission is shifting to the next gear. Without warning, the car completely turned off - engine failed - while driving and in the middle of making a turn, and luckily oncoming traffic stopped in time before we were in an accident. The local dealer has been unable to replicate the problem;…
