I understand how frustrating and alarming this can be.

But don’t worry – I’m here to help you figure out why your car is shaking at high speeds and what you can do about it.

In this blog post, we’ll dive into the most common reasons why cars shake at high speeds, how to diagnose the problem, and the solutions to fix it.

Reasons Why a Car Shakes at High Speeds

There are several reasons why your car may be shaking at high speeds. Let’s take a closer look at the most common ones:

Wheel Alignment Issues:

One of the most common reasons for car shaking at high speeds is wheel alignment issues.

When your wheels are not properly aligned, it can cause your tires to wear unevenly and create vibrations when you drive at higher speeds. This can also affect your steering and handling.

Tire Problems:

Another common culprit for car shaking is tire problems. This can be due to unbalanced or damaged tires.

When your tires are unbalanced, it means that the weight is not evenly distributed around the tire, causing vibrations.

Damaged tires, on the other hand, can cause the tire to bulge or develop a flat spot, creating shaking when you drive.

Suspension Issues:

Worn-out shocks or struts in your car’s suspension system can also cause shaking at high speeds.

These parts are responsible for controlling the movement of your car’s wheels and absorbing shocks from the road.

When they are worn out, it can cause your car to bounce or shake on the road.

Braking Problems:

Warped brake rotors can also lead to car shaking. When you apply your brakes, the brake pads press against the rotors to slow down the car.

If the rotors are warped, it can cause the brake pads to pulsate against them, creating shaking.

Engine Problems:

Finally, engine problems such as misfiring or worn-out spark plugs can also cause shaking. When your engine is not firing on all cylinders, it can cause vibrations in your car, especially at high speeds.

Diagnosing the Problem

Now that you know the most common reasons why your car may be shaking at high speeds, let’s talk about how to diagnose the problem:

Check Your Tires:

Start by checking your tires for any signs of damage or wear. Make sure they are inflated to the recommended pressure and that they are not unbalanced.

If you notice any issues, take your car to a tire specialist for a closer inspection.

Check Your Brakes:

Next, check your brakes to see if they are functioning properly. Look for any signs of wear on the brake pads or rotors, and test the brakes to see if they are pulsating or making any unusual sounds.

Check Your Suspension:

Inspect your car’s suspension system for any signs of wear or damage. Look for leaks in the shocks or struts and check the suspension mounts for any signs of looseness.

Check Your Engine:

Finally, if none of the above seem to be the problem, check your engine for any error codes or misfiring issues. You can do this by using an OBD-II scanner or taking your car to a mechanic.

Solutions to Fix the Problem

Depending on the root cause of the shaking, there are several solutions you can try:

Wheel Alignment:

If your car’s shaking is due to wheel alignment issues, a wheel alignment service can help.

A qualified mechanic will adjust the angles of your wheels to ensure that they are properly aligned, which can eliminate vibrations and improve your car’s handling.

Tire Balancing:

For unbalanced tires, tire balancing is the solution. This involves adding small weights to the tire to evenly distribute the weight around the tire, reducing vibrations and improving overall performance.

Tire Replacement:

If your tires are damaged, worn out, or have flat spots, it may be time to replace them. A qualified tire specialist can help you choose the right tires for your car and install them properly.

Suspension Repair:

For worn-out suspension components, repair or replacement may be necessary. This can involve replacing shocks or struts, or repairing any damage to the suspension mounts.

Brake Repair:

If your brakes are causing the shaking, brake repair or replacement may be necessary. This can involve replacing the brake pads or rotors, or resurfacing the rotors to eliminate warping.

Engine Repair:

Finally, for engine problems, a qualified mechanic can help diagnose and repair any issues with your engine. This may involve replacing spark plugs, fixing misfires, or repairing any other issues with the engine.

How to Find a Trusted Local Mechanic

Finding a trusted local mechanic can be a challenge, especially if you’re new to an area or don’t have any personal recommendations to go on.

However, there are several steps you can take to find a reliable mechanic that you can trust with your car.

One of the first things you can do is ask for recommendations from friends, family, or coworkers who live in the area.

You can also check online reviews and ratings for local mechanics to get a sense of their reputation and customer satisfaction.

Additionally, you may want to consider factors such as their certifications and experience, the types of services they offer, and their pricing and warranty policies.

By taking the time to research and compare different options, you can find a mechanic that you feel comfortable with and confident in their ability to keep your car running smoothly.

What Does it Cost to Have a Mechanic Do a Diagnostic?

If you’re experiencing issues with your car and are considering taking it to a mechanic for a diagnostic, you may be wondering about the cost.

The price of a diagnostic can vary depending on several factors, including the mechanic’s experience, the type of vehicle you have, and the complexity of the problem.

On average, you can expect to pay anywhere from $50 to $200 for a diagnostic, with some mechanics offering a free diagnostic if you choose to have the repair work done with them.

It’s important to keep in mind that a diagnostic is just the first step in the repair process, and the actual cost of repairs can vary depending on the extent of the problem and the cost of replacement parts.

However, by investing in a diagnostic early on, you can catch problems before they become more serious and potentially more expensive to fix.

Ultimately, the cost of a diagnostic is a small price to pay for the peace of mind and safety that comes with having a reliable and well-maintained vehicle.


Shaking in your car can be a scary and frustrating experience, especially at high speeds.

However, by understanding the most common reasons why cars shake at high speeds and how to diagnose and fix the problem, you can get back on the road with confidence.

If you’re experiencing shaking in your car, don’t hesitate to take it to a qualified mechanic for a thorough inspection and repair.

With the right care and maintenance, your car can provide smooth, reliable performance for years to come.
