Car juddering or shaking: decide when to stop
Last reviewed · OBDCode UK editorial
Do not keep driving to diagnose a severe or worsening shake.
ungraded — treat as general guidance
Can you keep driving?
Stop safely for a flashing engine-management light, damaged tyre, violent steering movement, brake-related shake, overheating, smoke or loss of power. A mild, stable shake with normal steering, braking and tyres permits only a short, low-speed trip to a nearby garage.
Checks you can make without dismantling anything
- Record whether the shake occurs at idle, while accelerating, at one road speed, while braking, or while steering.
- From outside the parked car, look for a visibly damaged or low tyre.
- Photograph warning lamps and note whether the engine runs unevenly.
- Do not perform high-speed, heavy-braking or repeated-acceleration tests on public roads.
Stop and arrange recovery when
- The engine-management light flashes or the engine runs very roughly.
- A tyre is bulged, cut, losing pressure or rubbing.
- Steering or braking is affected.
- The vibration is severe, rapidly worsening, or accompanied by smoke or overheating.
What to tell the garage
Give the garage the speed, gear, engine temperature, throttle or braking condition, warning lamps and a video if safely recorded while stationary.
