2020 Hyundai Venue Launch Control Problems, Symptoms, Causes and How to Fix

The 2020 Hyundai Venue has been reported to experience several control-related issues, primarily affecting its transmission and traction control systems. Owners have noted symptoms such as unexpected deceleration, difficulty in gear shifting, and the traction control light flashing without apparent cause. These problems are often attributed to failures in the transmission system or software glitches.

To address these issues, it is recommended to have the vehicle diagnosed at a certified Hyundai dealership. In some cases, a transmission replacement or software update may be necessary. Owners should also check if their vehicle is covered under warranty or any relevant recalls to potentially mitigate repair costs.

Symptoms

• Erratic RPM Fluctuations: RPMs revving up and down unexpectedly while maintaining constant pressure on the gas pedal.
• Difficulty Accelerating: Gradual loss of responsiveness from the gas pedal, leading to an inability to accelerate or maintain vehicle speed.
• Unexpected Vehicle Behavior: Car may lurch or shake unexpectedly, which can occur during acceleration or while maintaining speed.
• Transmission Issues: Potential for the transmission to fail, as indicated by sudden loss of power and inability to propel the car forward.
• No Warning Indicators: No service lights or warning indicators on the dashboard, despite the presence of significant mechanical issues.

Potential Causes

The causes of the 2020 Hyundai Venue launch control problems can be summarized as follows:

1. Transmission Issues: Problems with the continuously variable transmission (CVT), particularly when the vehicle is driven aggressively or used in conditions it’s not designed for, such as off-roading.
2. Software Glitches: Issues with the transmission control module or software that may affect the vehicle’s ability to shift gears or manage traction correctly.
3. Faulty Wheel Speed Sensors: These sensors can cause the traction control system to engage erratically or unexpectedly, especially noted during dry conditions.
4. Brake Fluid Leaks: Low or leaking brake fluid can impact the vehicle’s traction control system, leading to performance issues.
5. Aggressive Driving: Using the vehicle in a manner not suited to its design, like frequent hard accelerations or high-speed driving, can strain the transmission and other systems.

How to Diagnose Launch Control Issues in Your 2020 Hyundai Venue?

To diagnose launch control issues in your 2020 Hyundai Venue, follow these steps:

1. Check for Diagnostic Trouble Codes (DTCs): Use an OBD-II scanner to check for DTCs that may indicate specific transmission problems. Look for codes such as P0730, P0731, P0741, P0867, and P1603. If any of these codes are present, it suggests issues like incorrect gear ratios, torque converter problems, low transmission fluid pressure, or a TCU fault, which may necessitate transmission replacement.
2. Software Update: If DTCs are found, or if you’re experiencing transmission issues without a specific code, check for any available software updates for the transmission control unit (TCU). Hyundai has provided updates that may resolve existing issues.
3. Pressure Learning Procedure: After updating the TCU software or replacing the transmission, perform a pressure learning procedure. This step is critical to reset the adaptive values and ensure the transmission operates correctly after the repair.
4. Extended Test Drive: If no DTCs are present but issues persist, dealers may need to replicate the problem by driving the vehicle over an extended distance. Intermittent issues may not present an error code immediately and require longer driving periods to diagnose accurately.
5. Check for Other Symptoms: In addition to DTCs, pay attention to other symptoms such as erratic RPM fluctuations, difficulty accelerating, or unexpected vehicle behavior. These can provide clues to the underlying issue.
6. Consult Hyundai Dealership: If you’re unable to diagnose the issue yourself, or if the problem requires professional intervention, visit a certified Hyundai dealership. They have the necessary tools and expertise to diagnose and fix the problem, potentially under warranty.

How to Fix 2020 Hyundai Venue Launch Control Problems– Step by step

To fix the launch control problems in the 2020 Hyundai Venue, follow these step-by-step instructions based on Hyundai’s Technical Service Bulletin (TSB) 23-01-019H:

Step 1: Check Diagnostic Trouble Codes (DTCs)

• Use a diagnostic scanner to check for DTCs in the vehicle. Specifically, look for codes P0730, P0731, P0741, P0867, and P1603, which indicate issues with the transmission control unit (TCU) and the Intelligent Variable Transmission (IVT).

Step 2: Perform TCU Software Update

• Update the TCU software using the GDS Mobile software as per TSB 15-GI-001. This update is crucial to ensure the transmission operates correctly and may resolve existing error codes.

Step 3: Replace the IVT if Necessary

• If the DTCs persist after the software update, replace the IVT. Follow the vehicle shop manual for the correct replacement procedure. Ensure to use the specified parts and quantities as listed in the TSB, such as the correct model of IVT and the required transmission fluid.

Step 4: Perform IVT, TCU Pressure Learning

• After replacing the IVT or updating the TCU, perform the IVT, TCU Pressure Learning procedure. This step is critical to reset the transmission’s adaptive values and ensure it functions correctly. Follow the detailed steps in the TSB to complete this procedure accurately.

Step 5: Extended Test Drive

• Conduct an extended test drive to ensure that the issue is resolved. This is particularly important for intermittent issues that may not immediately trigger a DTC. The test drive should mimic the conditions under which the problem initially occurred.

Step 6: Verification

• After the test drive, recheck the system using the diagnostic scanner to ensure no new DTCs have appeared and that the previous codes have been cleared.

Step 7: Consult Hyundai Dealership

• If the problem persists or if you are unable to perform any of the steps, consult with a certified Hyundai dealership. They have the necessary expertise and equipment to diagnose and repair the issue effectively.
