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.

What stands out
Powertrain accounts for 34% of every owner complaint on file for this vehicle — the dominant problem area across 5 categories tracked.
Owners have filed 25 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.
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.
Certain Santa Cruz (NXT) vehicles equipped with 8-speed dual clutch transmissions (8DCT) may set one of the high pressure electric oil pump (HP EOP) DTCs listed below. This bulletin provides the service procedure to update the Transmission Control Unit (TCU) with improved logic to address these DTCs and enhance operation of the 8DCT.
full bulletin at NHTSA ↗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 2023 Hyundai Santa Cruz powertrain problems cluster around two critical failure modes: transmission limp mode and clutch slip, both causing sudden loss of acceleration.
Loss of Power in Limp Mode is the dominant complaint. Owners describe the vehicle entering limp mode—capped at 20–45 mph—without warning, often while accelerating from a stop or merging into traffic. Engine revs climb to 3,000–7,000 rpm but the vehicle refuses to respond. Some owners report the transmission stays stuck in a high gear and won't downshift; others say it refuses to upshift from 2nd or gets locked in 8th. The issue typically resolves after shutdown and restart, sometimes not. Diagnostic codes cited include P1C2D03, P193B79, and P087501. Dealers have diagnosed transmission oil pump faults, performed software updates, and in some cases replaced entire transmissions.
Clutch Slip and Judder during 1st-to-2nd gear acceleration causes the vehicle to shake and lose power momentarily. It happens randomly, roughly once per week for some owners, with no warning lights.
Secondary issues include engine rough starts or misfires on cold start, fuel injector defects (one dealer unable to obtain parts for 30+ days), and one case of engine stall while driving.
Critically, owners note Recall 22V746000 addressed transmission oil pump malfunction in 2022 Santa Cruz models but has not been extended to the 2023 model despite identical failures. Many dealers cannot reproduce the failures, refuse to repair without confirmed codes, or leave vehicles unrepaired for weeks. Safety concerns are pronounced: multiple owners describe near-accidents or incidents on highways where sudden power loss put them at risk of collision.

Transmission failed to transfer adequate power to the wheels when the accelerator was pressed from a full stop at the entry point of an intersection. This led to the the vehicle slowly entering the intersection for 2 feet over w seconds. Transmission then transferred full power to wheels. Vehicle was then driven to the entrance of the nearest parking lot, which required a left turn. Vehicle again…

On 3 separate occasions this has occurred . When accelerating, the engine or power train completely loses all propulsion. Twice I was starting a left hand turn and crossing oncoming traffic. On one occasion I was turning right onto a 50 MPH highway and quickly veered off the road onto the berm. The only item on dash board flashing on the third incident was the cruise control preset and it was…
