Car shaking — when driving, idling or accelerating
The cause of vibration depends on when it happens. Shaking at idle usually points to the engine; shaking at a certain speed points to the wheels or suspension.
Possible causes
- Engine misfires (plugs, coils, injectors)
- Worn engine mounts
- Unbalanced wheels or a damaged tyre
- Worn suspension or driveshaft parts
What you can safely check yourself
- Whether it shakes at idle, when accelerating or at a certain speed
- Whether the Check Engine light is on or flashing
- Whether any tyre has visible bulges or damage
When to call a mechanic
If the Check Engine light flashes and the engine jerks, reduce load and don't drive far — it can damage the catalytic converter.
How MobilaisServiss can help
We check engine operation with computer diagnostics and inspect the suspension to find the cause and agree the repair.
This is a general guide, not a diagnosis. The exact cause can only be confirmed after inspecting the car.
