Knowing exactly when your vehicle is shaking can help narrow down the cause.
Why Is My Car Shaking While Driving?
If you’ve ever wondered “why is my car shaking while driving?”The answer is complicated. Here are the top causes of a car shaking while driving, broken down into categories:
1. Tire Issues
- Unbalanced tires: If your tires aren’t balanced properly, your car shakes at high speed or around 60-70 mph. This causes steering wheel vibration at high speeds.
- Worn-out or damaged tires: A flat spot or uneven wear can lead to your car shaking at high speeds.
- Tire alignment: Poor alignment can cause your vehicle to shake while driving.
- Tire pressure: Overinflated or underinflated tires can cause a car to feel wobbly.
✅ Fix: Rotate, balance, or replace your tires. Ensure proper alignment and inflation.
2. Brake Problems
- If your car shakes when braking from 60 to 80 mph, the most common cause is warped brake rotors.
- Worn-out brake pads or calipers can also cause vibration when driving at 60mph.
✅ Fix: Replace or resurface the brake rotors. Inspect the entire braking system.
3. Engine-Related Issues
If your engine is shaking at idle or your car shakes when starting, these could be signs of:
- Worn spark plugs
- Clogged air or fuel filters
- Poor fuel injection system
- Misfiring engine cylinders
- Engine mounts failure
These issues often result in car shaking when idle, or a car that vibrates when idle. In some cases, you may even experience a car shaking check engine light.
✅ Fix: Replace spark plugs, clean fuel injectors, and inspect engine mounts.
4. Low Engine Oil or Lack of Lubrication
Have you noticed your car shaking while driving, especially when your car with low oil started shaking? This could be due to:
- Inadequate lubrication, causing metal parts to grind
- Engine overheating, resulting in engine vibration at idle
✅ Fix: Check oil levels and top up if necessary. Regular oil changes prevent engine damage.
5. Axle or Driveshaft Problems
- A bent axle or damaged driveshaft can cause serious car shaking when accelerating, especially during high-speed driving.
- If your car vibrates under acceleration, it could be due to faulty CV joints or universal joints.
✅ Fix: Inspect and replace the driveshaft or CV joints if needed.
6. Transmission Troubles
If your car shakes when accelerating but not when coasting, the transmission might be struggling to deliver power.
✅ Fix: Check transmission fluid levels and consider a diagnostic scan.
7. Suspension and Steering System
Suspension issues can cause car shaking when I drive, especially over uneven roads or at higher speeds. Signs include:
- Loose tie rods
- Worn ball joints
- Damaged control arms
✅ Fix: Have your suspension system checked and repaired.
8. Exhaust System Failures
A leaking or broken exhaust system can also lead to engine vibration at idle or even a car shaking when parked.
✅ Fix: Get a mechanic to check for exhaust leaks or broken hangers.
