P0920 on Hyundai by model: symptoms, diagnosis and fix
The 7-speed dual-clutch transmission (DCT) paired with the 1.6L turbo engine in Tucson models suffers from shuddering during low-speed maneuvers, hesitation from a stop, and jerky shifts. The dry clutch design is prone to premature wear. Hyundai addressed it with TCU software updates (including safety recall 16V-628 for delayed engagement on 2016 models and TSB 21-AT-014H for low-speed judder); clutch replacement falls under normal warranty coverage.
Common Symptoms
- Shuddering at low speed (1st-2nd gear)
- Hesitation when accelerating from stop
- Jerky gear changes
- Transmission warning light
- RPM flaring between shifts
How to Fix
Check for open recall 16V-628 (2016 models) and ask the dealer to apply TSB 21-AT-014H (judder inspection and TCU update); clutch replacement under this TSB is covered by normal warranty. A TCM software update can improve shift quality. If clutch is worn, the dual-clutch assembly replacement is needed (Hyundai part 41200-2D220). Dealer replacement costs $1,800-3,000. Some owners have had success with the software update alone.

Owner tips & cautions
- TipRequest the latest TCM software calibration from the dealer - newer versions significantly improve shift quality
- TipLet the DCT warm up for 2-3 minutes before driving aggressively - cold clutch engagement causes most shuddering
- WarningIf the transmission warning light comes on, get it inspected immediately - continued driving can damage the clutch beyond software repair

Sonatas equipped with the dual-clutch transmission can experience shuddering, hesitation, and jerky engagement at low speeds. The DCT can feel rough in stop-and-go traffic. This is a characteristic of the dry-clutch DCT design.
Common Symptoms
- Shudder at low speeds
- Hesitation from stop
- Jerky engagement
- Rough shifting in traffic
- Clunking when shifting
How to Fix
Have transmission software updated to latest calibration. DCT clutch actuator replacement may help in severe cases. Keep transmission cool - avoid heavy traffic in hot weather. Some owners have had clutch packs replaced.
Owner tips & cautions
- TipGet a proper diagnosis before replacing parts - similar symptoms can have different causes
- TipSearch Hyundai Sonata forums and owner groups for real-world experiences and DIY guides
- TipGet multiple quotes from independent mechanics - dealer prices can be 2-3x higher for the same repair

Kona models with the 1.6L turbo and 7-speed DCT experience shuddering during low-speed driving, delayed engagement from a stop, and lurching during parking maneuvers. The dry dual-clutch design struggles with heat and wear. Hyundai TSB 22-AT-007H (May 2022) covers low-speed DCT judder on 2018-2021 Kona 1.6T with a TCU software update and, if needed, double-clutch replacement.
Common Symptoms
- Shuddering in 1st-2nd gear
- Delayed response when pressing gas from stop
- Lurching in parking lots
- Transmission overheat warning
- Harsh shift from 2nd to 3rd
How to Fix
Request the latest TCM software calibration from the dealer (TSB 22-AT-007H covers 2018-2021 models). If clutch is worn, the entire dual-clutch assembly needs replacement (TSB 22-AT-007H includes a double-clutch replacement procedure). TCM update is free; clutch replacement is $1,500-2,800 out of warranty. Avoid riding the clutch in stop-and-go traffic.

Owner tips & cautions
- TipIn heavy stop-and-go traffic, shift to manual/sport mode to reduce DCT hunting between gears
- TipLet the car warm up for 1-2 minutes before driving - cold clutch engagement causes most of the shudder
- WarningDo not ignore the transmission overheat warning - pull over and let it cool for 15 minutes to prevent clutch damage

The 6-speed dry DCT offered with the non-turbo 1.6 GDI Veloster is prone to premature clutch wear and failure, often before 60,000 miles. Symptoms include slipping, shuddering, and complete loss of drive. The dry clutch design generates excessive heat in stop-and-go traffic. Hyundai addressed DCT drivability with TCM software updates (e.g., TSB 14-AT-011 on 2012 cars); no DCT-specific warranty extension was found.
Common Symptoms
- Slipping in higher gears
- Shuddering from stop
- Loss of drive in traffic
- RPM surging without acceleration
- Burning clutch smell
How to Fix
Check whether the car is still within Hyundai's 10-year/100,000-mile original-owner powertrain warranty. Clutch assembly replacement is needed when worn (Hyundai part 41200-2A001). Cost is $1,500-2,500 out of pocket. TCM software update helps but does not prevent eventual failure.

Owner tips & cautions
- TipIf buying a used Veloster Turbo, strongly consider the manual transmission version - the DCT is the single biggest reliability concern
- TipIn stop-and-go traffic, shift to neutral at red lights to reduce heat on the DCT clutch
- WarningIf you smell burning clutch, stop driving immediately - continued driving can damage the flywheel and increase repair cost by $500+

Frequently asked questions
What does P0920 mean on a Hyundai?
P0920 stands for "Gear Shift Forward Actuator Circuit/Open." P0920 indicates an open circuit in the gear shift forward actuator circuit. In transmissions that use electronic shift actuators, this actuator helps engage forward gear ranges; an 'open' means the control module isn't seeing a complete electrical circuit to that actuator. The code is treated as serious because it can prevent the transmission from shifting or engaging gears properly. Symptoms may include inability to select or stay in a forward gear, harsh or no engagement, a transmission warning light, or limp-mode behavior. On Hyundai it is documented across 4 models: Tucson, Sonata, Kona, Veloster.
What are the most common causes of P0920?
The most common causes of P0920 are: Open or broken wiring in the actuator circuit, Faulty gear shift forward actuator, Corroded, loose, or disconnected connector, Moisture or corrosion on circuit contacts, Damaged wiring harness near the transmission, Poor ground or open power feed to the actuator, Faulty transmission control module (less common). The specific cause varies by vehicle.
How much does it cost to fix P0920 on a Hyundai?
Repair costs vary widely with the root cause and Hyundai model; each issue on this page carries its own estimate where one is published.
