BMW 640i Gran Coupe Car is shaking or vibrating Inspection at your home or office.

Common reasons for this to happen:

• Tire issues: The most frequent causes of a vehicle shaking while driving stem from tire issues. Tires begin to behave differently when worn or out of balance. Tire replacement, realignment, and rebalancing are common solutions.


• Engine firing issues: When one or more of your spark plugs isn’t firing correctly, it can cause your car to vibrate. Typically, this problem will also cause your check engine light to illuminate. If a misfire is responsible, a loss of power or “hesitation” will usually accompany the vibration.


• Brake system issues: If the vibration or steering-wheel shake only occurs when you apply the brakes, it’s likely time to have your brake pads and rotors checked. As rotors are subjected to heat, puddles, and stress, the metal tends to deform. A warped rotor can occur at anytime, but may also indicate the need for your brake pads to be replaced.

• Engine mount issues: The motor mount connects the engine to your vehicle’s chassis, and is designed to isolate engine noise and vibration from the passenger compartment. As mounts wear over time, the vibration may be more pronounced at idle while in gear, and may change when the vehicle is placed in neutral or park. Broken motor mounts can lead to larger problems in the driveline, and should be promptly addressed.

• Suspension issues: Issues with your front suspension can also cause your vehicle to shake or vibrate. When this is the case, your car will act normally when stopped, but will begin vibrating during changes in speed or when traveling over bumps. Suspension problems may also be accompanied by odd noises like periodic clunks, squeals, and squeaks.
