What causes the engine to shake in a Kia Ceed?

My Kia Ceed's engine has started shaking when I reach high speeds. Is this a sign of a serious problem and what should I do about it?

It's possible that your engine mounts are worn out and need to be replaced. This is a common issue in Kia Ceeds and can cause shaking at high speeds. I would recommend taking your car to a mechanic for an inspection.

Another potential cause could be a misfiring engine. This can happen when the spark plugs are worn out or the fuel injectors are clogged. I suggest getting a tune-up to address these issues.

If your car is also making unusual noises or producing black smoke from the exhaust, it could indicate a problem with the engine's cylinders. In this case, it's important to visit a mechanic as soon as possible.
