Investigating Unusual Car Vibrations and Solutions

The “Chevy Shake” refers to a problem some Chevrolet owners face—a noticeable vibration while driving at speeds typically between 35 and 70 mph.

This isn’t just an annoyance; it’s a concern that could impact the way you control your vehicle and its overall reliability.

The issue is most commonly reported in certain General Motors models, including the Chevrolet Silverado and Cadillac Escalade. The Chevy Shake has not only led to a flurry of owner complaints but has also been the subject of technical scrutiny and legal challenges.

In this blog, we’ll go through what causes the Chevy Shake, which models are most affected, and what you can do if your vehicle has this problem.

What is the Chevy Shake?

The Chevy Shake is primarily identified by a persistent vibration that occurs when driving at moderate speeds, usually between 35 and 70 mph.

If you own a Chevrolet and have experienced this, you’re likely feeling vibrations through the steering wheel or the seat, which can be quite unnerving and may raise concerns about the safety and integrity of your vehicle.

This issue predominantly affects a range of General Motors vehicles, including the Chevrolet Silverado, GMC Sierra, and Cadillac Escalade, particularly models produced between 2014 and 2019.

Owners of these vehicles have frequently reported the problem, which has become a well-recognized issue within the Chevrolet community.

Affected Models and Scope

The Chevy Shake is a significant issue that affects a variety of General Motors vehicles, particularly impacting some of the most popular models. Here’s a breakdown of the models most commonly associated with this problem:

  • Chevrolet Silverado: Reports of the Chevy Shake are especially prevalent in Silverado trucks, affecting multiple model years from 2014 to 2019.
  • GMC Sierra: Similar to the Silverado, the Sierra has also been affected, with owners reporting the same unsettling vibrations during operation.
  • Cadillac Escalade: Luxury meets discomfort as this high-end SUV has not been spared from the Chevy Shake, especially in models from the same time period.

The vibration issues in these models are typically experienced under specific driving conditions, such as when accelerating or maintaining speeds on the highway. The problem often manifests more noticeably at speeds between 35 and 70 mph.

Possible Causes of the Chevy Shake

Now, you should understand the root causes of the Chevy Shake to address and resolve the issue effectively. Here are the primary factors believed to contribute to this pervasive problem:

  • Driveshaft Concerns: The aluminum driveshafts used in these vehicles are often cited as a central cause. These components may not adequately absorb vibrations or may themselves produce resonances at high speeds, leading to the characteristic shaking.
  • Transmission Issues: The eight-speed automatic transmissions in these models have been problematic. Issues with the transmission’s design, such as hydraulic system faults, can cause improper torque conversion and lead to vibrations that drivers feel while operating the vehicle.
  • Improper Vehicle Alignment and Balance: Sometimes, the Chevy Shake can be exacerbated or caused by poor alignment or balancing of the vehicle. This includes improperly balanced tires or wheels that can magnify any existing vibrations from the drivetrain.
  • Wear and Tear on Suspension Components: Worn suspension components can also contribute to the severity of the shaking, as they fail to dampen the vibrations effectively.

Manufacturers’ Acknowledgment and Actions on Chevy Shake

General Motors (GM) has recognized the Chevy Shake issue, albeit with varying degrees of responsiveness and transparency over the years. Here’s how the manufacturer has addressed the problem:

Technical Service Bulletins (TSBs)

GM has issued several TSBs with potential fixes like updating software and changing transmission fluids. These are aimed at reducing the vibrations that drivers experience.

Communication with Owners

The feedback from vehicle owners about GM’s communication has been mixed. Some owners are satisfied with the dealership’s response, where attempts are made to fix the issues under warranty.

However, others are frustrated by the lack of effective solutions or by GM’s portrayal of the shake as a normal characteristic of these models.

Engineering Changes and Updates

In response to the complaints, GM has modified the engineering of newer models. These changes are supposed to improve the drivetrain and suspension systems to minimize vibrations.

Public Statements and Media Response

GM’s public statements often describe the Chevy Shake as a characteristic of certain models and not as a defect. This approach has not been well received by everyone, leading to demands for more transparent and effective solutions from GM.

If you own a used GM vehicle that’s shaking, knowing your rights under lemon law for used cars can be crucial. These laws might provide you with a way to address chronic problems with your used vehicle, potentially leading to compensation or other remedies.

Legal Actions and Recourse You Can Take on Chevy Shake

As the Chevy Shake issue persists in severity, many vehicle owners have taken legal steps to address their grievances. Here’s an overview of the legal actions being pursued:

Class Action Lawsuits

Numerous class action lawsuits have targeted General Motors, claiming that the Chevy Shake drastically reduces the usability, safety, and resale value of the vehicles. If you are dealing with this issue, it’s wise to consult with Lemon Law Assist to understand your rights and options within these class actions.

Individual Legal Claims

Apart from class actions, some owners have filed individual lawsuits under lemon laws and other consumer protection statutes. These personal legal claims detail the owners’ repeated failed attempts to fix the vibrations and often demand remedies such as vehicle replacement or full refunds.

Arbitration and Settlements

For quicker resolution, some owners choose arbitration, which can be less cumbersome than court trials. There have been instances where GM has settled these disputes out of court, offering varying levels of compensation to the vehicle owners.

Consumer Advocacy

Additionally, affected owners have rallied through consumer advocacy groups and online forums to share their experiences and unite their voices. This collective action has been crucial in increasing public pressure on GM to address the issue more effectively.

Conclusion

The Chevy Shake issue affects numerous General Motors vehicles, causing significant vibrations that raise concerns about comfort and safety. This problem is especially common in models like the Chevrolet Silverado and Cadillac Escalade from the years 2014 to 2019.

Despite GM’s efforts, including technical service bulletins and vehicle modifications, many owners believe the problem persists. As a result, class action lawsuits have been filed seeking justice and compensation.

If your vehicle is affected, it’s important to keep detailed records and consider consulting with a Lemon Law Attorney to understand your options for recourse. This proactive approach can help you secure a fair resolution.
