A significant [class-action lawsuit](https://www.carexplore.com.au/holden-class-action-lawsuit-are-you-affected/) has been launched against General Motors (GM) Australia and New Zealand, targeting transmission defects in several popular Holden models. 

With potentially “*hundreds of thousands*” of vehicles involved, this legal battle could impact Holden owners nationwide, spanning models like the **Holden Commodore VE**, **Holden VF Commodore**, **Holden Colorado**, and others.

## **The Allegations: Faulty Holden Transmissions**

Maurice Blackburn, the law firm leading the case, alleges that three automatic transmissions—**GM 6L45**, **6L50**, and **6L80**—are defective due to a design fault in the torque converter and torque converter clutch. These issues reportedly affect vehicles sold between *January 1, 2011*, and *December 24, 2024*.

According to Maurice Blackburn Principal Lawyer Kimi Nishimura:

> “Because of the alleged defect, car owners have experienced problems with their vehicles including intermittent transmission shudders, excessive vibrations, and harsh gear shifts.”

## **Reported Problems in Holden Vehicles**

The transmission issues have led to widespread complaints from affected Holden owners, including:

- **Transmission Shudder**: Frequent and intermittent vibrations during operation.
- **Fluid Leaks**: Reports of automatic transmission fluid leaking.
- **Component Wear**: Accelerated degradation of internal transmission parts.
- **Increased Servicing**: Owners have faced higher maintenance costs and requirements.

## **GM’s Statement**

General Motors has declined to comment on the ongoing litigation but reaffirmed its commitment to Holden customers. A spokesperson stated:

> “GM does not comment on ongoing litigation. GM stands by its commitment to achieving the best outcomes for Holden customers.”

## **Affected Holden Models**

The class action includes a wide range of **Holden Commodore** and **Holden Colorado** vehicles, along with derivatives like the **Holden Ute**, **Holden Calais**, and **Holden Caprice**. Affected vehicles span multiple model years and transmissions:

| **Model**                | **Model Year** | **Transmission** |
| ------------------------ | -------------- | ---------------- |
| **Colorado 7**           | MY12-MY16      | 6L50             |
| **Colorado**             | MY17-MY20      | 6L50             |

Other models such as the **Holden Calais**, **Holden Captiva**, and **Holden Rodeo** may also be impacted.

## **Historical Class Actions in Australia**

This is not the first time Australian automakers have faced lawsuits for vehicle defects:

- **Ford PowerShift Transmission**: In 2016, Ford Australia was ordered to compensate owners for defective dual-clutch transmissions.
- **Toyota DPF Class Action**: Toyota faced a class action in 2019 for defective Diesel Particulate Filters (DPFs), leading to compensation payouts to owners.

## **Your Rights and Next Steps**

If you owned or currently own a vehicle affected by the **Holden transmission class action lawsuit**, you may be entitled to compensation—even if you haven’t experienced any issues yet. Maurice Blackburn encourages all eligible parties to register for the lawsuit.

## **Why This Matters**

This lawsuit highlights the importance of consumer rights in Australia’s automotive industry. With popular models like the **Holden Commodore VE**, **VF Commodore**, and **Holden Colorado** involved, this case could lead to significant outcomes for owners across the country.
