Is the Accord's Pedestrian Protection Covered by Insurance Claims?

After the pedestrian protection device is triggered, you can file a claim with the insurance company. Additional information: 1. Pedestrian Protection Technology: Mainly involves the application of energy-absorbing materials on the vehicle body, such as energy-absorbing bumpers, soft hood materials, and headlights and accessories without sharp edges. Among these, the use of buffer structure design on the engine hood cross-section is a more common practice among domestic automakers. 2. Application of Collision Buffer Protection System: A typical model is the Honda Accord. The Accord is equipped with a movable hinge at the end of the hood lift. When a pedestrian is hit, the hinge causes the hood to sink, thereby achieving the effect of buffering and protecting the pedestrian. Additionally, the collision margin space reserved in the front fender and bumper also serves a buffering role.

Why is water dripping under the car?

Reasons for water dripping under the car: 1. The car windows were not tightly closed during rainy days; 2. Issues with the drainage outlets. If water still drips under the car cabin after eliminating human factors, the car's drainage outlets should be checked; 3. Long-term accumulation of debris blocking the drainage holes, especially in vehicles with sunroofs, as opening the sunroof makes it easier for debris to accumulate and cause leaks. Methods to handle car leaks: 1. Remove accumulated water inside the car using dry towels or water scooping tools; 2. Check which parts and components inside the car are damaged. If the damage is severe, timely repairs at a repair shop are necessary; 3. Identify the cause of the leak by checking the four common reasons mentioned above one by one.
