Car Shakes When Accelerating

Car shaking when accelerating can be an unsettling and potentially dangerous situation. Diagnosing the cause is key to fixing the problem and restoring a smooth, comfortable driving experience. In this article, we will discuss some of the most common causes of car shaking during acceleration and provide solutions to address them.

Important Outline

There are several potential reasons why a car may shake when accelerating. Understanding the primary causes can help you diagnose the issue and take proper action to fix it. Here’s an outline of the main factors contributing to this problem:

1. Engine-related issues
2. Transmission problems
3. Tire and wheel imbalances
4. Drivetrain and suspension component issues
5. Brake system problems

1. Engine-Related Issues

A poorly functioning engine can lead to shaking during acceleration. Engine problems that could cause shaking include faulty spark plugs, worn-out engine mounts, and issues with the fuel or air intake systems. Regular maintenance, such as spark plug replacement and cleaning of the air and fuel filters, can help address these issues and prevent them from causing car shake.

2. Transmission Problems

An issue with the transmission can also lead to car shaking when accelerating. If there’s a problem with the transmission fluid or internal components, shifting gears may become challenging and lead to vibrations. Check the transmission fluid levels and consider a transmission fluid change to rule out transmission-related issues.

3. Tire and Wheel Imbalances

A common cause of car shaking during acceleration is imbalances in the tires and wheels. Tire issues, such as uneven wear, misalignment, or damage, can cause your car to shake as you pick up speed. Inspecting your tires regularly for signs of wear and imbalance and checking the tire pressure can help ensure a smoother driving experience.

4. Drivetrain and Suspension Component Issues

Issues with the drivetrain and suspension components can also create shaking during acceleration. Damaged or worn-out components, including CV joints, bearings, and suspension bushings, can contribute to an unstable driving experience. If you suspect any of these components are causing the shaking, consult a professional mechanic for a thorough inspection and repair.

5. Brake System Problems

Although less common, issues with the brake system can also lead to car shaking during acceleration. Warped brake rotors, sticky brake calipers, and malfunctioning brake components can all contribute to vibrations when speeding up. Regular brake maintenance, including replacement of worn components and brake fluid changes, can help keep your braking system in good working condition.


In summary, a car that shakes when accelerating can have many potential causes, ranging from engine and transmission issues to problems with the tires or brakes. Regular vehicle maintenance and inspections can help identify and address these issues before they become more serious concerns. If you’re unsure about the cause of your car’s shaking, it’s best to consult with a professional mechanic to diagnose and repair the problem.

Step by Step Guide

This section provides a step by step guide to address car shaking when accelerating. Follow these steps to diagnose and rectify the problem.

1. Inspect your engine: Check for any visible issues, such as damaged belts, hoses, or mounts. If you find any issues, replace the damaged components.

2. Check spark plugs: Inspect and clean the spark plugs, and replace them if they’re worn or damaged.

3. Test the engine’s air and fuel systems: Clean the air filter, fuel filter, and ensure there are no obstructions in the intake system.

4. Inspect the transmission: Check the transmission fluid levels and quality. Replace the fluid if necessary, and consult a mechanic if you suspect internal transmission issues.

5. Examine your tires: Check for tire damage or uneven wear, and ensure they’re properly balanced, aligned, and inflated.

6. Investigate drivetrain and suspension components: Inspect the CV joints, bearings, and suspension bushings. Replace worn or damaged parts as needed.

7. Analyze the brake system: Examine the brake rotors, calipers, and other brake components for signs of wear or damage.

Step by Step Guide With Bullet Points

– Inspect the engine for visible issues
– Check and replace spark plugs if needed
– Clean air and fuel filters and ensure no obstructions in the intake system
– Check transmission fluid levels and quality; replace if necessary
– Inspect tires for damage, balance, alignment, and pressure
– Examine drivetrain and suspension components for wear and damage
– Analyze brake system components for signs of wear or damage

Pros and Cons

– Maintaining your car regularly can prevent issues like car shaking
– Proper maintenance can prolong the life of your vehicle
– Following the step by step guide can save you money on mechanic fees
– Early diagnosis can prevent small issues from turning into expensive repairs

– Though the guide is comprehensive, you may still require a professional mechanic for some issues
– Not all car shaking issues can be addressed through these steps; additional troubleshooting may be needed
– Some vehicle owners may find the process time-consuming or challenging


Q: How often should I check my spark plugs?
A: Most manufacturers recommend checking your spark plugs every 30,000 miles, but this can vary depending on the specific make and model of your vehicle. Consult your vehicle owner’s manual for more specific guidance.

Q: What are the most common causes of tire imbalances?
A: The most common causes include uneven tire wear, worn suspension components, and incorrect tire pressure or alignment.

Q: Can I diagnose and fix transmission issues myself?
A: Checking transmission fluid levels and changing the fluid can be done by most vehicle owners. However, diagnosing and fixing internal transmission issues usually requires a professional mechanic.


Car shaking during acceleration can be caused by various factors, and following the outlined step by step guide can help you identify and address most of these issues. However, if you’re having trouble diagnosing the cause or if you believe the issue is more complex, it’s best to consult a professional mechanic. Regular vehicle maintenance and inspections can help prevent car shaking and ensure a smooth and comfortable driving experience.
