Car pressure loss indicates insufficient tire pressure, which is a warning given by the tire pressure monitoring system. After receiving this alert, it is essential to identify which tire has low pressure and then inflate and adjust it accordingly. Tires are a crucial component of a car, as they directly affect the vehicle's driving stability and safety. Tire pressure is of great importance to the tires themselves. The tire pressure should neither be too high nor too low. If the pressure is too low, the tires may experience wave-like deformation during high-speed driving, increasing the risk of a blowout and reducing the tire's lifespan. If the pressure is too high, the contact area between the tire and the ground decreases, leading to reduced tire grip, which can negatively impact the car's handling and driving stability.

Recently, my car also experienced a sudden drop in tire pressure, which I found quite strange. There could be several possible reasons: first, the tire might have a small puncture or leak from running over something sharp unnoticed while driving; second, the valve core might be aging or loose, causing air to slowly leak out; third, the pressure might naturally drop due to colder temperatures, especially noticeable in winter; fourth, the tire pressure monitoring system might have falsely reported a fault; fifth, the tire itself might be severely worn, leading to poor sealing. When low pressure is detected, it's essential to check immediately, as it can affect handling, such as unstable turning, increased risk of a blowout on highways, and higher fuel consumption. I recommend regularly checking with a simple tire pressure gauge and visiting a repair shop for patching or replacing parts if the pressure continues to drop. The tire pressure monitoring system is a great helper, and regular calibration can reduce false alarms.

How ABS Works?

The Anti-lock Braking System (ABS) operates as follows: During braking, ABS rapidly determines the wheel lock-up state based on speed signals from each wheel speed sensor. It closes the normally open input solenoid valve on the wheel that begins to lock, maintaining constant braking force. If the wheel continues to lock, it opens the normally closed output solenoid valve, causing the braking pressure on that wheel to rapidly decrease as it connects directly to the brake fluid reservoir, preventing complete wheel lock-up due to excessive braking force. This keeps the braking state at the optimal point (with a slip ratio S of 20%), achieving the best braking effect and maximum driving safety. The brake fluid in the front chamber of the master cylinder is under dynamic pressure, pushing the reaction sleeve to the right, which in turn pushes the booster piston, moving the brake pedal push rod to the right. Therefore, when ABS is active, the driver can feel vibrations in the pedal and hear some noise. After the vehicle decelerates, once the ABS computer detects that the wheel lock-up state has disappeared, it closes the main control valve, returning the system to normal braking operation. If the accumulator pressure drops below the safety limit, the red brake fault indicator and amber ABS fault indicator light up. In this case, the driver must apply greater force with a deep pedal press to achieve effective braking on both front and rear wheels. ABS Classification: ABS can be categorized by manufacturer or by control channel. The following mainly introduces the channel classification method. In ABS, a brake pipeline capable of independent brake pressure regulation is called a control channel. ABS devices are classified into four-channel, three-channel, two-channel, and one-channel systems. Performance Characteristics: The anti-lock braking system enhances safety during emergency braking. In other words, vehicles without ABS may experience wheel lock-up during emergency braking, rendering the steering wheel immobile, thereby increasing the risk of severe consequences. Advantages: When a wheel is about to reach the next lock-up point, the brake fluid pressure causes the system to repeat its action, operating 60–120 times per second, akin to continuous braking and releasing, similar to mechanical "cadence braking." Thus, ABS prevents loss of steering control and wheel skidding during emergency braking, ensuring wheels do not lock up and preventing tires from rubbing against the ground at a single point, thereby increasing friction and achieving over 90% braking efficiency. It also reduces brake wear, doubling the lifespan of brake drums, discs, and tires. Vehicles equipped with ABS achieve slip resistance performance of 80%–90% on dry asphalt, 10%–30% in rain, and 15%–20% in snow. Limitations: ABS itself has limitations and cannot defy certain physical laws. In two scenarios, ABS does not provide the shortest braking distance: first, on smooth dry roads when braking is performed by an experienced driver; second, on loose gravel, soil, or deep snow surfaces. Additionally, on dry surfaces, the latest ABS systems can control the slip ratio within 5%–20%, but not all ABS systems operate at the same rate or degree. Although four-wheel ABS can brake the vehicle in the shortest possible distance, if braking is initiated too late to stop completely before colliding with an obstacle, it cannot prevent the accident.

Who is Responsible for Car Damage During Rental?

During car rental, the responsibility for car damage lies with either the renter or the rental company. The specific details are as follows: Scenario 1: If the car was originally in good condition and the damage was caused by the renter during driving, the renter should bear the responsibility. Scenario 2: If it is found that the car had pre-existing issues and the renter did not operate it improperly, the rental company should bear the responsibility. Scenario 3: If the car had pre-existing issues and the renter also operated it improperly during driving, both parties should share the responsibility. Here are ways to avoid being held responsible for car damage during rental: Rent from a reputable car rental company. Since cars are valuable and prone to various issues during use, reputable rental companies offer better guarantees in terms of vehicle performance, safety, insurance, and service. Carefully review the rental contract terms before signing. Typically, car rental companies provide a pre-drafted contract for signing. Always read such standard terms carefully before signing, especially the clauses on how to handle malfunctions during use. Inspect the car thoroughly during the handover process. For any special features or usage methods of the car, consult the rental company for clarification.

How to Get Compensation for a Vehicle Recall?

Vehicle recalls typically involve compensation measures such as extended warranties, coupons, or gifts, which generally do not impose significant impacts on 4S stores. Below are some common faults that often lead to vehicle recalls: Steering Assembly: Component failures in the steering assembly and braking assembly, which, under normal circumstances, can lead to reduced braking performance during regular driving. Fuel Assembly: Component failures in the fuel assembly, such as sudden engine shutdowns during driving or leakage of unidentified fluids like engine oil or gasoline under the chassis. Engine Assembly: Issues in the engine assembly mainly involve abnormal engine noises and stuck accelerator pedals. Abnormal engine noises are particularly critical—minor cases may involve clogged intake systems, while severe cases could result in damage to piston rods or crankshafts. Quality Issues: Tire cracking, cracks, or bulging within 80,000 kilometers or three years are considered quality issues. Similarly, pungent odors from seatbacks or interior materials that persist for a long time also fall under quality issues.

Where to Check Car Fuel Consumption?

You can directly observe the data calculated by the car's onboard computer, which is displayed on the dashboard or manually calculated by yourself. Below are the relevant introductions about onboard computer calculation and manual calculation: Onboard Computer Calculation: For better-looking data, the fuel consumption calculated by the onboard computer is generally slightly lower than the actual fuel consumption because the computer defaults to zero fuel consumption when the car is idling. Therefore, the onboard computer's fuel consumption data can only serve as a reference and is not 100% accurate. Manual Calculation: Car fuel consumption = fuel consumed / distance traveled, with the unit being L/km. For example, if you add 300 yuan worth of gasoline to an empty tank and drive 500 kilometers, and assuming gasoline costs 7 yuan per liter, the average fuel consumption of the car would be 8.5L/km.
