When accelerating or decelerating, the clunking noise in the chassis can be caused by the following reasons: Suspension System: The noise heard when starting the vehicle is usually due to a fault in the suspension system, which may be caused by loose or damaged engine mounts. Steering and Suspension Systems: The noise heard when turning the vehicle may be due to faults in the steering and suspension systems, as the vehicle tilts during turning, causing the suspension system to deform and participate in the movement. Braking System Components: The noise heard when driving on good road conditions may be due to faults in the braking system components, such as loose or worn parts, out-of-round brake drums, or uneven brake discs. Bearing System: It could also be an issue with the bearings that connect moving and stationary parts of the vehicle. If it's a bearing problem, the driver can identify it by applying slight brakes. If the noise remains unchanged when braking at a constant speed, then the issue is with the bearings.

Why was the Geely Vision X3 discontinued?

Reasons for the discontinuation of the Geely Vision X3: 1. Prolonged market downturn: Due to the market slump caused by outdated standards, the Vision X3 is gradually being phased out. However, not all models in the Vision series have been discontinued; the Vision X6 is still being retained. 2. The Vision X6 offers great value for money: As a compact SUV, the Vision X6 has gained consumer favor with its affordable pricing, similar to that of small SUVs, and its sales have entered the top 20 in the domestic SUV sales rankings. Additionally, the newly added 1.4T 6AT powertrain has further enhanced its market competitiveness. This is precisely why the Vision X6 has been retained in the market competition for new products. 3. The strong rise of new models: The new model replacing the Vision series, codenamed SS11, is positioned as an entry-level compact sedan or small car. Its competitive advantages will focus on aspects such as cost-performance ratio and size, aiming to capture market share from AO-class sedans.

Will High Tire Pressure Trigger an Alarm?

The high tire pressure warning light will illuminate, indicating the need for tire inspection and pressure adjustment. According to the international GBT2978-2008 standard, the recommended tire pressures for different types are as follows: Standard tires: 2.4-2.5bar; Reinforced tires: 2.8-2.9bar; Maximum pressure: should not exceed 3.5bar. Hazards of excessive tire pressure: Reduced tire friction and adhesion, affecting braking performance; Causes steering wheel vibration and deviation, reducing driving comfort; Accelerates uneven wear on the central tread pattern, shortening tire lifespan; Increases vehicle vibration, indirectly affecting the lifespan of other components; Overextends tire cords, reducing elasticity and increasing load during driving; Decreases puncture resistance. Sharp objects like nails or glass can easily penetrate, causing internal cracks or blowouts.

Can the Car Door Be Left Open for a Long Time?

The car door should not be left open for a long time. There is a sensor probe on the edge of the door frame. When the door is closed, the probe is in a closed state and disconnected from power. When the door is opened, the probe activates and remains powered. Keeping the door open for an extended period can lead to battery drain. Below are specific details about the car battery: 1. Function: The battery provides power for starting the car and operating electronic devices inside the vehicle. If the car battery is drained, it may prevent the car from starting normally. If the battery voltage is too low, it can cause difficulty in starting the car or even make it impossible to start. 2. Charging: If the battery runs out of power, it is best to remove it and charge it using a battery charger. In emergency situations, jump-starting can be used to charge the battery. Jump-starting requires a rescue vehicle and two charging cables, which should be prepared beforehand.
