Ford Focus · 2012–2018
The DPS6 PowerShift 6-speed dual-clutch automated transmission fitted to 2012-2018 Ford Focus (and 2011-2019 Fiesta) is widely considered one of the worst transmission designs in modern automotive history. The dry dual-clutch design was fundamentally unsuited for stop-and-go driving, producing violent shuddering during low-speed acceleration, hesitation when pulling away from stops, unexpected surging, and abrupt harsh shifts. Ford knew of the defects from the start but concealed them and continued selling vehicles. Multiple class action lawsuits resulted in settlements covering 2012-2016 models (expanded to 2017-2018). Ford issued dozens of TSBs and software reflashes that repeatedly failed to fix the underlying mechanical problem. The TCM (Transmission Control Module) failures are a distinct but related issue. Repair options include clutch replacement (temporary fix), TCM reprogramming, or complete transmission replacement.
Common Symptoms
- Violent shuddering or juddering when accelerating from a stop
- Transmission hesitates or refuses to move in Drive for 1-3 seconds
- Unexpected lurch forward when releasing brakes at low speed
- Grinding or clunking between gear changes
- Transmission surging and jerking during low-speed driving
- Vehicle bucks and shakes at 15-35 mph (clutch slip zone)
- Transmission warning light or "Transmission Fault" message
- Loss of drive in one or both gears
- Delayed engagement from Park to Drive
How to Fix
Check fordtransmissionsettlement.com for class action settlement eligibility. Ford's warranty extended to cover repeated repairs. Updated clutch service parts: Focus uses F1FZ-7B546-B clutch (replaces BV6Z-7B546-F). TCM repair/replacement per TSB 16-0109. Software recalibration via IDS tool at dealer. For definitive fix: remanufactured DPS6 transmission. Many owners chose to pursue buyback via state Lemon Laws. Latest settlements include 2017-2018 models under separate class action.

Hyundai Tucson · 2016–2021
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 extended the DCT warranty to 10 years/100,000 miles under a settlement.
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 if vehicle is covered under Hyundai DCT warranty extension (10yr/100k miles). A TCM software update can improve shift quality. If clutch is worn, the dual-clutch assembly replacement is needed (Hyundai part 41200-2D100). 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

Hyundai Kona · 2018–2023
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 extended DCT warranty to 10 years/100,000 miles after class-action pressure.
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. If clutch is worn, the entire dual-clutch assembly needs replacement (covered under extended warranty if applicable). 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

Frequently asked questions
What does P0920 mean?
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.
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?
Repair costs for P0920 range from $500 to $20,000, depending on the vehicle and root cause.
