What Causes a Car to Shake When Accelerating and Braking?
There are several reasons why a car may shake when accelerating or braking. It’s essential to identify the root cause of the problem to determine the best course of action. Here are some possible causes:
Worn or Loose Belts
A worn or loose serpentine belt can cause the engine to vibrate, leading to a shaking sensation when accelerating or braking. Over time, belts can wear out or become loose due to wear and tear, causing the engine to misfire or vibrate excessively.
Bad Wheel Bearings
Bad wheel bearings can also cause a car to shake when accelerating or braking. When the bearings wear out, they can cause the wheels to wobble or vibrate, leading to a shaking sensation.
Unbalanced Wheels
Unbalanced wheels can also cause a car to shake when accelerating or braking. When the wheels are not properly balanced, they can cause the vehicle to vibrate or shake, especially when driving at high speeds.
Clogged Air Filter
A clogged air filter can also cause a car to shake when accelerating or braking. When the air filter is clogged, it can restrict airflow to the engine, causing it to vibrate or misfire.
Low Tire Pressure
Low tire pressure can also cause a car to shake when accelerating or braking. When the tires are underinflated, they can cause the vehicle to vibrate or shake, especially when driving at high speeds.
What Are the Symptoms of a Car Shaking When Accelerating and Braking?

Unusual Noise
Another symptom of a car shaking when accelerating and braking is an unusual noise. This can include a grinding, whining, or screeching sound coming from the engine or wheels.
Difficulty Accelerating or Braking
Difficulty accelerating or braking can also be a symptom of a car shaking when accelerating and braking. This can include a hesitation or lag when pressing the accelerator or brake pedal.
How to Diagnose and Fix the Problem?
Diagnosing and fixing the problem of a car shaking when accelerating and braking requires a combination of observation, inspection, and testing. Here are some steps to follow:
Observe the Vehicle
The first step in diagnosing the problem is to observe the vehicle. Look for any signs of vibration or shaking, and take note of any unusual noises or difficulties with acceleration or braking.

Check the Air Filter
Check the air filter for any signs of clogging or damage. Look for any blockages or restrictions in the airflow, and check for any signs of damage or wear on the filter.
Consult a Mechanic
If you’re unable to diagnose the problem yourself, it’s a good idea to consult a mechanic. A professional mechanic can use specialized tools and equipment to diagnose the problem and recommend the necessary repairs.
Recap and Conclusion
In conclusion, a car shaking when accelerating and braking can be caused by a variety of factors, including worn or loose belts, bad wheel bearings, unbalanced wheels, clogged air filters, and low tire pressure. The symptoms of this problem can vary depending on the cause, but common symptoms include vibration or shaking sensations, unusual noises, and difficulty accelerating or braking. To diagnose and fix the problem, it’s essential to observe the vehicle, check the belts and hoses, check the wheel bearings, check the tires, check the air filter, and consult a mechanic if necessary. By following these steps, you can identify and fix the problem, and get back on the road with confidence.
