Whether it starts suddenly or gradually increases over time, Shaking in your vehicle isn't a problem that should be ignored. Shaking can indicate a serious issue with your car that needs to be addressed by an expert mechanic. Excess shaking may be due to a few different issues, ranging from clogged filters or loose parts to damage sustained in a car accident.

Engine

If the shaking in your car begins when you start it up, the engine might be causing the vibrations. The engine has a few parts that can lead to shaking or vibrating if they are damaged or otherwise not working properly. The engine contains parts called spark plugs that help the engine produce power. Most are designed to last around 80,000 to 100,000 miles, but your car's spark plugs may need to be changed more or less frequently. Faulty spark plugs may be accompanied by unusual sounds coming from the engine. The engine air filter, another essential part, can stifle the engine's oxygen levels if it gets too dirty, interrupting the engine's performance.

Brakes

When you step on the brakes, the car should come to a smooth and quick stop. If the brake pedal shakes when you press on it, the brakes might need attention. The brakes contain multiple parts that can wear out and lead to abnormal vibrations, including the rotors and pads. The rotors and pads will last about 50,000 miles or so. The brake pads have a cushion that generally keeps the rotors from hitting each other. If the brake pads wear out, the rotors produce heat and friction when they touch due to the metal-on-metal impact. Excessive or uneven wear might also cause shaking from the brakes.

Wheels

Wheels that become damaged, such as bent or dented, can lead to shaking in the car, too. Wheel-related shaking usually gets worse with acceleration and prolonged driving. Other parts in the wheels may also wear out over time with wear and tear, including the ball joints and wheel bearings. Wheels can also spin incorrectly and produce excessive shaking. Parts on the wheels can loosen and contribute to the shaking, too, including the lug nuts.

Axles

The axles have a few parts that can wear out, including the driveshaft and the CV joints. Those parts can cause your vehicle's shaking, and it usually worsens with acceleration. The axles might start shaking suddenly after an accident, which indicates that they may be damaged from the impact.

Tires

The tires on your car should be rotated about every 5,000 – 6,000 miles. If you don't have them inspected frequently, problems can arise that cause the vehicle to shake. Hitting potholes or having an accident can also cause tire damage. Uneven wear, tread loss, or low pressure can also cause shaking.
