If you’ve ever noticed your car shaking when you step on the accelerator pedal, you know how unsettling and potentially dangerous it can be.

This issue can lead to damage to different components of the engine such as the gearbox, suspension system, wheel axle, and a few components related to the combustion system, if left unaddressed.

Let’s discuss common causes of a car shaking when accelerating and provide you with practical solutions to get your vehicle back on track.

Common Causes of Car Shaking When Accelerating

Here we go:

1. Misaligned Wheels

Misaligned wheels can lead to uneven tire wear and cause your car to shake when accelerating. When your wheels are not properly aligned, they can pull in different directions, creating vibrations as you accelerate.

Solution: Visit a reputable auto shop to have your wheels professionally aligned. Regular wheel alignments can also extend the life of your tires.

2. Suspension Problems

A compromised suspension system, such as worn-out shocks or struts, can lead to a bumpy and shaky ride, especially when accelerating or driving over rough terrain.

Solution: If you suspect suspension issues, consult a professional mechanic to assess and replace any worn-out components.

3. Combustion Problems

Issues like engine misfires, faulty spark plugs, or clogged fuel injectors can cause your car to shake when accelerating. These problems disrupt the smooth combustion process.

Solution: Have your vehicle’s engine checked by a qualified mechanic. Replacing spark plugs and addressing any misfires or fuel injector problems can often resolve this issue.

4. Exhaust System Concerns

A damaged or clogged exhaust system can disrupt the flow of exhaust gases, affecting engine performance and causing vibrations.

Solution: Inspect your exhaust system for damage, leaks, or blockages. Repair or replace damaged components to restore proper exhaust flow.

5. Wheel Hub or Bearing Issues

Worn-out wheel hubs or bearings can create excessive play in the wheel assembly, leading to vibrations when you accelerate. This issue can also generate unusual noises, such as grinding or humming.

Solution: If you suspect wheel hub or bearing problems, have them inspected and replaced as needed by a professional mechanic.

6. Brake Problems

Brake issues, like warped brake rotors or brake pad irregularities, can result in shaking sensations, especially when braking and accelerating simultaneously. The uneven braking force can cause the car to shake.

Solution: Have your brakes inspected, and replace worn-out brake components to ensure even braking and a smoother ride.

7. Transmission Troubles

Problems with the transmission, such as a malfunctioning torque converter and low transmission fluid can lead to vibrations during acceleration, particularly in automatic transmissions.

Solution: Consult a transmission specialist to diagnose and repair any transmission-related issues.

8. Axle Shaft Problems

A damaged or bent axle shaft can disrupt the rotation of the wheels, causing your car to shake when accelerating. This issue may also manifest as a clicking or clunking sound during turns.

Solution: Replace a damaged axle shaft to restore proper wheel rotation and eliminate vibrations.

How to Fix the Problem

  1. Regular Maintenance: Stay on top of routine vehicle maintenance, including oil changes, air filter replacements, and fluid checks. Proper maintenance can prevent many of the issues that lead to shaking during acceleration.
  2. Wheel Balancing: If you feel vibrations in the steering wheel, consider having your wheels balanced. Balanced wheels ensure even weight distribution and a smoother ride.
  3. Check Engine Light: If your check engine light is on, don’t ignore it. Visit an auto repair shop to diagnose and address any underlying engine issues promptly.
  4. Professional Inspection: If you can’t pinpoint the problem or if the shaking persists, consult a professional mechanic. They have the expertise and equipment to diagnose and repair complex issues.
  5. Tire Replacement: If your tires are excessively worn or damaged, it may be time for a replacement. Invest in quality tires and ensure proper alignment and rotation.


Remember that diagnosing the exact cause of your car’s shaking when accelerating may require professional expertise.

If you’re unsure about what exactly causing this issue in your car, you must consult a qualified auto mechanic who can conduct a detailed inspection and suggest repairs to get your vehicle back to smooth and safe driving on the roads.
