Note when it happens
Why does my car shake?
A shake or vibration is your car pointing at something out of balance or worn. The most useful clue is when it happens. A shimmy at highway speed often means the tires, a shudder only when braking often means the rotors, and a rough shake at idle can point at the engine.
Most likely causes
Ranked from most to least common.
- 1Unbalanced, worn, or damaged tires (common at highway speed)
- 2Warped brake rotors (a shudder felt through the pedal when braking)
- 3A worn wheel bearing or a bent wheel
- 4An engine misfire from worn spark plugs or coils (rough at idle)
- 5Worn suspension or a failing CV axle
What you can check
Safe, simple things to look at yourself.
- Notice the speed or situation where the shake appears
- Does it come through the steering wheel, the seat, or the brake pedal?
- Check the tires for uneven wear or a visible bulge
- See whether a check-engine light is on, which points toward a misfire
What to do next
Match the timing of the shake to the likely area, then have that system checked. A tire balance or a rotor service resolves a large share of these.

Common questions
Why does my car shake?
A shake or vibration is your car pointing at something out of balance or worn. The most useful clue is when it happens. A shimmy at highway speed often means the tires, a shudder only when braking often means the rotors, and a rough shake at idle can point at the engine.What is the most common cause?
The single most common cause is unbalanced, worn, or damaged tires (common at highway speed). Also worth ruling out: warped brake rotors (a shudder felt through the pedal when braking), and a worn wheel bearing or a bent wheel. Match the timing of the shake to the likely area, then have that system checked. A tire balance or a rotor service resolves a large share of these.What can I check myself first?
Start with the safe checks: notice the speed or situation where the shake appears. Then does it come through the steering wheel, the seat, or the brake pedal?. Anything beyond that is worth leaving to a shop.
You deserve a fair fix.
