A car that shakes when you turn it on does not inspire confidence, yet it’s not uncommon to feel a slight (or perhaps not-so-slight) vibration after starting the ignition. Here are the top reasons a car might shake upon starting.
A troubled engine can lead to a heap of difficulties, a trembling car among them. Maybe it lacks enough air, fuel or spark to run efficiently. Dirty filters and faulty spark plugs can often start your engine on a downward path.
The crankshaft damper can also cause the engine to vibrate. Since this part’s primary function is to prevent shaking, a defective one can have an alarming effect. The longer you go without repairing the issue, the more intense the vibrations will become.
If you feel other symptoms of engine dysfunction, like a jerk upon acceleration or shaking after the car has run smoothly, see a professional right away. The engine is your car’s lifeline. You don’t want to risk it.
Warped brake rotors can make a car shake when it’s started. The rotor, a round, silver component of the brake system, can begin to lose its original shape with wear and tear. When this happens, it flattens and can cause intense vibrations in the car. Having a comprehensive brake check can help identify the problem and repair the issue.
Although many people assume tire trouble commonly makes a vehicle vibrate, it can also be the wheels. For instance, if clay or mud gets stuck to the wheels, it can cause imbalance and lead to vibration. Having tires and wheels cleaned regularly can prevent such buildup.
Most automobiles have two axels–one connecting to the front wheels and another to the back. If either becomes dented or bent (which can happen after a driving mishap or accident) it can cause vibrations. Generally, if an axel is to blame, the vibrations will intensify with acceleration.
If your car feels shaky following a collision, contact a mechanic right away.
Did you know frosty weather can make an engine vibrate more than normal? As chilly air causes the engine to operate below optimal levels, increased shaking is common. Luckily, no drastic measures should be taken; the issue will resolve itself once conditions warm up.
