What Causes the Noise When Starting a Car After It Has Been Parked for Several Days?

This situation occurs because the moisture between the brake pads and brake discs has not completely dried, causing them to adhere more tightly. The noise will disappear after driving for a while. If the noise persists, it is recommended to visit a repair facility. Below is additional information: Function of Brake Pads: To ensure better coordination between the brake pads and brake discs, maintain the proper operation of the braking system, and restore normal braking performance. Brake Disc Maintenance Methods: Develop good driving habits, avoid sudden braking, regularly inspect the brake pads and discs, check the thickness of the friction material, have a professional inspect the brake shoes, and use original equipment manufacturer (OEM) brake pads and discs when replacing them.
Once when I parked my car for a week during a business trip, I heard a squeaking noise upon starting. It's quite common—most likely the brake pads rusted and stuck to the rotors due to rain or moisture corroding the metal, causing friction and noise when moving. Tires can also deform if left stationary for too long, producing slight noises that usually disappear after a few minutes of driving. If the suspension bushings aren't properly lubricated, they may squeak when dry during startup. Additionally, sludge buildup in the engine can cause vibrations and noise upon acceleration. Before long-term parking, it's advisable to check the brake system and apply anti-rust lubricant. Taking short drives regularly or keeping the garage dry can prevent this issue—don't ignore it, as it affects driving safety.
Back when I was repairing cars, I encountered many such cases. The squeaking noise when starting after the car has been parked for a few days is usually caused by rusted brake pads sticking together. Dry or insufficiently lubricated suspension points can also produce squeaky sounds. Tire deformation isn't a major issue and usually corrects itself after driving a short distance. I recommend trying gentle throttle application when starting - if the noise persists, check for brake pad wear or loose chassis screws. Don't forget to lubricate suspension bushings and key points to prevent future issues. A quick safety check before hitting the road always brings peace of mind. This is a common and easily solvable problem, so no need to worry too much.
